Background

[0001] Many types of medical devices are provided for home use and home therapy. Examples of such medical devices includes respiratory machines, homecare beds, wheelchairs, etc. One type of respiratory machine provided to users is an oxygen concentrator. Oxygen concentrator systems provide elevated concentrations of oxygen to assist users in breathing.

[0002] Such systems are known to be either stationary, transportable, or portable. Stationary systems are intended to remain in one location such as, for example, a user’s home, bedroom or living room. Transportable systems are intended to be moved from location to location and often include wheels or other mechanisms to facilitate movement. Portable systems are intended to be carried with the user such as, for example, via a shoulder strap or similar accessory.

[0003] These and other medical devices are located near the user such as, for example, in the same room or may be located in another room. Even when in the same room, the medical device may be located some distance away from the user. This may be because that is where the nearest electrical outlet is located or because the medical device may create a level of noise during operation. This situation requires the user to get up and walk to the medical device when turning the device on and off and/or making adjustments. However, most user’s requiring medical devices such as oxygen concentrators, for example, have reduced strength and/or stamina and such movement may be difficult. Further yet, emergencies and/or medical incidents may occur in the user’s home. It is desirable to address these and other aspects of providing medical care at home and/or a care facility. Summary

[0004] Systems and methods are provided remotely controlling a medical device. In some embodiments, systems and methods are also provided for remote medical monitoring. This includes, for example, emergency/panic notifications/functions, medical event recording, compliance monitoring, sleep timer and environmental controls, two-way communication, and other functions such as, for example, emergency telephony/communication in various forms. In other embodiments, systems and methods for managing a remote control of a medical device are provided. This includes, for example, two-way communication for assisting in locating the remote, power management including sleep mode and wireless charging, and master remote/key functionality. The remote can be handheld or wearable and may include, for example, audio, visual, haptic, input, communication, and sensor (including biosensor) functionality. Other embodiments are disclosed as well. In this manner, the remote control can not only control the medical device, but also provides the user with extended functionality for emergency and non-emergency communication and tasks. The remote can also provide locally available information to the user when the user is not close enough to the controlled unit or medical device to get such information as alarms, status, conditions, settings, dosage, usage, etc. The remote can provide information and feedback to its user visually, with audio cues, haptic or other sensory feedback.

Description

[0018] Embodiments of the present inventions provide, for example, systems and methods for remote control and communication with a medical device and/or a (remote) network or system. The systems and methods can include, for example, a remote control that can be handheld and/or wearable. Wearable embodiments include, for example, pendant and wrist wearable remote controls. As will be described in more detail, the remote control can include, for example, a processor, memory and input and output devices such as buttons, lights, visual displays, audio speaker(s) and microphone(s), tactile or vibration device(s), communication modem(s) and radio(s), biosensor(s), accelerometer(s), gyroscope(s), light sensor(s), etc. and combinations of the foregoing.

[0019] In one embodiment, a system and method use a remote control having functionality for controlling the medical device and functionality for emergency and/or distress situations. Emergency and/or distress functions can include telephony or other network communication (wired or wireless) to provide audio, video, email, mobile app notifications, and/or text messages to local emergency services (i.e. , 911 calls), medical provider and/or private call service, one or more family members, one or more friends, etc. and combinations of the foregoing. In another embodiment, the emergency and/or distress functions can include, for example, “man down” alarms that detect falls and/or impacts to a person. The “man down” alarms can include an audible local alert signal and be with or without telephony or other network communication distress messaging as described herein. In yet another embodiment, the emergency and/or panic functions can include a GPS-based distress signal emitted via very high radio frequency (VHF) or other type of powerful radio signal allowing emergency services to pick up the signal and locate its sender within a wider geographic area. In yet another embodiment, the emergency and/or panic functions can include sending a distress signal to a nursing and/or aide’s station within a medical (or other care facility) and/or senior-living facility or community. In yet another embodiment, the emergency and/or panic functions can interface with a medical alert system already existing within the user’s home, care, and/or living facility or community. By way of these examples and embodiments, the systems and methods can use a remote control, whether in combination with or without the medical device itself, to generate signals, data and information indicating an emergency and/or distress situation is present.

[0020] In another embodiment, the systems and methods use a remote control for indicating one or more medical events have occurred. For example, a user can create an input on the remote control to indicate one or more medical event(s) have occurred. This can, for example, create data indicating a time-stamp (e.g., date and time) of the medical event(s). The medical event can be any medical event experienced by the user such as, for example, a respiratory event (e.g., breathing difficulty, asthma, coughing, congestion, etc.), cardiac event (e.g., irregular heartbeat, slow heartbeat, fast heartbeat, angina, etc.), fever, headache, sinus pain, etc. In other embodiments, the medical event data can further include biosensor data along with the time and date data. Biosensor data can include, for example, body temperature, EKG, heart beat/rate/variability, blood pressure, blood oxygen concentration, breathing rate, activity level, respiratory flow rate, respiratory volume, etc. In a further embodiment, the data also include medical device settings and diagnostic information such as, for example, flow settings, pressure settings, configuration settings, device usage (days, hours, minutes, seconds), device identification information, etc. [0021] In another embodiment, the systems and methods use a remote control for inputting compliance monitoring information. For example, the systems and methods may prompt a user to provide input on a remote control during certain time intervals to confirm use and/or compliance with the therapy (e.g., oxygen therapy). The remote control can provide a cue or signal (e.g., a prompt) to the user indicating an input is required to confirm compliance. The cue or signal can include, for example, one or more of audio, visual, and/or tactile signals presented to the user. Upon such a prompt, the user can, for example, provide the compliance input by pressing or depressing a button on the remote control device indicating compliance with the therapy. In a further embodiment, the remote control device can include one or more prompts reminding the user that treatment or therapy should be begin. The prompt can be based or initiated on a timer indicating the device has not been used for a certain time period (e.g., hours, etc.) or a timer based on a particular time (e.g., time of day, week, etc.) indicating therapy or treatment should begin. In such a case, the remote control would generate a prompt to initiate treatment or therapy.

[0022] In yet another embodiment, systems and methods use a remote control for providing sleep timer signals for the medical device and/or controlling devices in the user’s environment such as, for example, lights, thermostats, door locks, garage doors, televisions, radios, and other devices. The remote control can include sleep timer functionality for turning the associated medical device(s) off and/or on at the expiration of a set timer. For example, a remote control can set a time or sleep timer for turning off an oxygen concentrator medical device in, for example, 5, 10, 15, 20, etc. minutes. The remote control can also set a time or timer for turning on the medical device at a particular time or at the expiration of a timer. The logic for turning the medical device on and off based on time and timer data can be located either in the remote control or in the medical device itself. And, the remote control can transmit the time/timer data and/or on and off signals to the medical device to accomplish these functions. In some embodiments, the medical device will include the logic for receiving the time and/or timer data and configure itself to be turned on and/or off based on that data without further input from the remote control. In other embodiments, the remote control can directly turn the medical device on and/or off through transmission of such signals to the medical device based on the time and/or timer input by the user.

[0023] In yet further embodiments described herein, systems and methods are provided for locating a lost remote control, power and/or energy management of a remote control, charging the power source of a remote control, matching a paired remote control to a medical device within a warehouse setting, awakening from sleep mode a medical device stored in a warehouse upon receiving a signal from its paired remote control, and/or using a remote control as a master remote control that can communicate or be paired with any and/or all associated medical devices, including when a original remote control is lost for any one medical device.

[0024] Referring now to Figure 1, one embodiment 100 of a system and method for a remote control and a medical device is illustrated. A medical device 102 and a remote control 104 therefore is provided. Medical device 102 can be, for example, any medical device suitable for remote control including respiratory machines (oxygen concentrators, nebulizers, CPAP’s, ventilators, etc.), homecare/hospital beds, etc. The present embodiments illustrate an oxygen concentrator device as medical device 102 but the disclosure herein is not limited to such a device. Oxygen concentrators provide elevated concentrations of oxygen to assist users in breathing. Oxygen concentrating systems and methods are disclosed in, for example, U.S. Pat. Nos. 4,449,990, 5,906,672, 5,917,135,

5,988,165, 7,294,170, 7,455,717, 7,722,700, 7,875,105, 8,062,003, 8,070,853,

8,668,767, 9,132,377, 9,266,053, and 10,010,696 which are commonly assigned to Invacare Corporation of Elyria, Ohio and fully incorporated herein by reference.

[0025] Remote control 104 can be in any form including, for example, wearable 106 and 108 and handheld 110. Wearable forms include a wrist wearable 106 and/or a pendant wearable 108. Other forms are also possible. Remote control 104 can include, for example, a processor, memory and input and output devices such as buttons, lights, visual displays, audio speaker(s) and microphone(s), tactile or vibration device(s), communication modem(s) and radio(s), biosensor(s), accelerometer(s), gyroscope(s), light sensor(s), etc. and combinations of the foregoing. (See also, Fig. 13 and related description). Remote control 104 wirelessly communicates 112 with medical device 102 to accomplish a range of functions and processes, as described herein. The wireless communication can be, for example, optical (infrared), radio-frequency (Bluetooth, Wi-Fi, VFIF, etc.), etc.

[0026] In one embodiment, the medical device 102 includes hardware and logic/software for sending data/information to a cloud network 116, which can include one or more remote servers, telephones, smart phones, computers, tablets, etc.) Medical device 102 communicates with the cloud network 116 via a wireless and/or wired communication 114. This can include for example, cellular, Bluetooth, Wi-Fi, VFIF, LAN, ethernet, fiber optic, etc. communication. The data/information can include, for example, text messages 118, email messages 120, video 122, audio/voice 124, etc. (See also, Fig. 14 and related description).

[0027] Remote control 104 includes software and logic for controlling medical device 102. This includes, for example, on/off functions and/or operational settings. In the case of an oxygen concentrator, this can include on/off, modality (e.g., continuous or pulsed flow), oxygen flowrate settings (e.g., 0-5 liters per minute), sleep timer, wake timer, silence alarm(s), reset, etc. Remote control 104 includes one or more input devices such as, for example, buttons and/or a touchscreen, for receiving inputs from the user and transmitting them to the medical device for control thereof.

[0028] In one embodiment, remote control 104 includes emergency and/or distress communication and functionality. Remote control 104 includes one or more buttons or inputs the user can press when an emergency or distress situation occurs. This can be any medical situation including, for example, cardiac, pulmonary, circulatory, muscle, skeletal, neurological, psychological, mobility (e.g., falls or impacts to the body), etc. situations experienced by the user where the user is in some form of distress or in need of emergency assistance.

[0029] In one embodiment as shown in Fig. 1, remote control 104 transmits 112 the emergency or distress signal to medical device 102. Medical device 102 can then transmit 114 the emergency or distress signal via any one or more of its outputs including text messages 118, email messages 120, video messages 122, and/or audio or voice messages 124. These messages can be transmitted to any one or more of local emergency responders, medical providers, medical alert call service, family members, and/or friends. These messages can include any one or more of the following types of information including, for example, location, username and address, type of medical situation and/or distress and/or emergency, etc.

[0030] Medical device 102 can further include visual and audible distress indicators to further assist in the transmission and awareness of the emergency/distress signal. In a related embodiment, medical device 102 may only generate visual and/or audible distress indicators if cloud or network connectivity is not provided. The visual distress indicators can include, for example, one or more lights or displays flashing and/or providing visual cues, icons, or messages. The audible distress indicators can include, for example, buzzing, alarm, and/or chirp sounds indicative of an emergency and/or distressful situation.

[0031] Referring now to Figure 2, another embodiment 200 of a system and method for a remote control and medical device having emergency communication and functionality is illustrated. In this embodiment, a GPS-based distress signal 202 is generated. The signal includes GPS data/information to help locate the user in distress. The GPS-based distress signal 202 can be transmitted 204 wirelessly including, for example, via any radio-frequency (e.g., Bluetooth, Wi-Fi, VFIF, UHF, etc.) In one embodiment, GPS-based distress signal 202 can be generated and transmitted 204 by remote device 104 upon user initiation (e.g., pressing a distress button, initiating a distress function) or automatically generated upon predetermined conditions (e.g., the user fell down, the user has stopped moving for a significant period of time, the users vital functions are low or at critical levels, etc.) In a related embodiment, the GPS-based distress signal 202 can be generated and transmitted 206 by medical device 102 in response to the user transmitting a distress or emergency situation via remote control 104 or any of the aforementioned conditions. Medical device 102 can also generate a distress signal and transmit 114 it to the cloud network 116. The GPS-based distress signal 202 has the advantage of providing the GPS location of the user to assist local emergency responders, medical providers, medical alert call services, family members, and/or friends in locating the user.

[0032] Figure 3 illustrates an embodiment 300 of a system and method for remote control and medical device having emergency communication and functionality within an assisted living or medical care environment. In this embodiment, an emergency/distress signal is generated and can be transmitted 302 by a remote 104 to a nursing/aide’s station 304. The user can generate the emergency/distress signal by, for example, any of the methods or conditions previously described. The distress/emergency signal can include, for example, information identifying the patient and/or their location within the facility or environment.

[0033] The nursing/aide’s station 304 (and/or receiver) can also include logic for prioritizing the emergency/distress signal within other alarms integrated or otherwise generated at the nursing/aide’s station by other systems. For example, the emergency/distress signal can be prioritized to have low, medium, or high priority (e.g., see bar icons/displays 306 (low), 308 (medium), 310 (high)). A high priority can place the emergency/distress signal above, for example, a general assistance or similar signal that may be received by the nursing/aide’s station 304. A low or medium priority can place the emergency/distress signal below, for example, a trauma or other similar signal at the station.

[0034] The nursing/aide’s station 304 can include a receiver having one or more alarms 312 and/or 314. Alarm 312 can include, for example, a visual alarm such as a message, display, and/or indicator light. The visual alarm 312 can also be colorized for priority. For example, yellow can indicate a low priority. Orange can indicate a medium priority. And, red can indicate a high priority. Other colors and indicators/cues including blinking or flashing may also be used alone or in combination with the foregoing.

[0035] Alarm 314 can include one or more audio, visual, haptic and/or other sensory feedback. Examples include an audio alarm such as a buzzer, tone, a plurality of tones, and/or voice. Audio alarm 314 can also include priority cues including slow repeat rate tone(s) for low priority alarms, a medium repeat rate tone(s) for medium priority alarms, and a high repeat rate tone(s) for high priority alarms. Audio alarm 314 can further include escalating volume, intensity, and/or duration for any of the above conditions. Other examples include haptic cues such as vibrations and/or pattern of vibrations or haptic pulses. For example, the patterns of vibrations or haptic pulses can be sequenced to designate certain information. A single pulse or vibration can represent patient 1 , room 1 , or alarm level 1 , two pulses or vibrations can represent patient 2, room 2, or alarm level 2, etc. Similarly, the sequence an include long and/or short vibrations or haptic pulses. A long pulse, followed by a short pulse, followed by another long pulse, can represent patient 101 , room 101 , or alarm level 101 , etc. The use of haptic feedback provides a discreet notification option. In these ways, a nurse or aide can see, hear, and/or feel the priority of the alarms and emergency/distress signals from remote device 104 and decide what is the appropriate action needed based on the information represented by the sensory feedback. [0036] As previously described in connection with Figure 2, medical device 102 can be triggered by remote device 104 to generate and transmit 316 an emergency/distress signal to nurse/aide’s station 304. Medical device 102 can also transmit the signal to the cloud network 116. In this manner, the emergency/distress signal can be transmitted to multiple places for assistance or attention.

[0037] Figure 4 illustrates an embodiment 400 of a system and method for remote control and medical device having emergency communication and functionality that communicates with a medical alert system 404. A medical alert system includes, for example, an alarm system that can generate a signal indicating the presence of a hazard or emergency requiring immediate attention and can call and/or message emergency medical personal, an emergency service, family members and/or friends. Remote device 404 can generate and transmit 404 an emergency/distress signal to medical alert system 404 according to any of the previously described methods and means. Also, medical device 102 can generate and transmit 406 an emergency/distress signal to medical alert system 404 either on its own or based on receipt of such a signal from medical device 104. This is accomplished by pairing remote device 104 and/or medical device 102 to medical alert system 404 so they can communicate with each other. In this manner, medical alert system 404 can be triggered to call and/or message for help or assistance using its own services.

[0038] Referring now to Figure 5, one embodiment 500 a system and method for medical event recording is illustrated. Medical event information 502 is generated by remote device 104 to indicate a medical event has occurred. Medical event information 502 can be transmitted 112 to a receiving device 506 that can be, for example, medical device 102, nurse/aide’s station 304, medical alert system 404, smart phone/tablet 508, etc. In a further embodiment, the receiving device 506 can transmit 114 the medical event information 502 to cloud network 116 or save it to internal memory for later retrieval, transmission, and/or analysis. [0039] In one embodiment, the medical event information 502 can include a timestamp of when the medical event occurred. This information can include, for example, year, month, day, hour, minute, and/or second of occurrence. In other embodiments, this information can further include biosensor data such as for example electrocardiogram (EKG), blood pressure, blood oxygen level, heart rate (and other cardiac measurements), breathing rate and airway occlusions (including partial) (and other pulmonary measurements), etc. One or more of these sensors are either part of remote device 104 or communicate with remote device 104 to provide the sensor data information (see e.g., Figure 13, biosensors 1324). Therefore, medical event information 502 can include timestamp and sensor data/information.

[0040] In operation, the user can provide an input such as, for example, depressing a button or other input, on remote device 104 to indicate a medical event has occurred. Examples of medical events include breathing issues (e.g., asthma, shortness of breath, difficulty breathing, etc.), cardiac issues (e.g., pain in the chest, fast heartbeat, slow heartbeat, heart attack, etc.), headaches, dizziness, etc. In one example, the user may depress a “medical event” button on remote device 104 each time the user experiences a cardiac issue. Logic within remote device 104 creates a timestamp of the event and, as described previously, may further record some or all of the associated biosensor data/information. In another example, the user may depress the “medical event” button on remote device 104 each time the user experiences a pulmonary or breathing issue. This medical event information 502 can then be transmitted to, for example, medical device 102, nurse/aide’s station 304, medical alert system 404, smart phone/tablet 508, etc. and then further to cloud network 116 where a medical service provider, physician’s office, hospital, etc. can receive the information for use in the care of the user.

[0041] Figure 6 illustrates one embodiment 600 of a system and method for monitoring user compliance in, for example, use of the medical device or therapy provided by the medical device. Remote device 104 can include a compliance input such as, for example, a button, that the user must press during a time interval to indicate compliance in using the medical device 102 or the therapy provided thereby. For example, if the medical device 102 is an oxygen concentrator and the therapy is breathing with elevated oxygen concentration levels, the user may be required to press the “compliance” button, or submit a blood oxygen saturation measurement via a sensor or paired sensing device, during certain time intervals 604 (e.g., every 30 minutes) to signal or indicate compliance with the therapy. Logic 602 can be provided that generates an audio 608 and/or visual 606 cue to the user that it is time 604 to provide a compliance input (e.g., by for example pressing a compliance button or other input on remote device 104). Thus, for example, 3 hours of therapy can require 6 compliance inputs by the user (e.g., one compliance input on cue every 30 minutes). Other time intervals 604 can also be chosen.

[0042] Visual cues 606 can include, for example, a display, message, illuminated or flashing input or button, etc. Audio cues 608 can include, for example, a buzzer, tone, tones, and/or voice sounds indicating a compliance input is required. A compliance input by the user shuts off the visual/audio cue until the next time interval 604 expires and the user is prompted by the cues to provide a compliance input. Logic 602 also generates and collects compliance data 610 in regard to the user input. For example, compliance data 610 can include the total amount of therapy time indicated by user compliance inputs. If the compliance interval is, for example, every 30 minutes, then each user input will add 30 minutes of compliance time to the total.

[0043] In other embodiments, compliance data can further include date and/or time information such as, for example, year, month, day, hour, minute, and/or second. This allows the compliance data 610 to indicate with detail the compliance usage including duration and pattern of usage (monthly, weekly, time of day/night, etc.) Compliance data 610 can be transmitted 112 to medical device 102 for storage or further transmission (including bulk user compliance data 612) to cloud network 116 where a provider, insurer, physician’s office, hospital, etc. can receive the information for assessment and care of the user.

[0044] Compliance logic 602 can reside either in remote device 104 or medical device 102. In the case of medical device 102, a signal can be transmitted 112 to remote device 104 to cue the user to provide a compliance input that would generate a signal back to medical device 102 that a compliance input has been made. In other embodiments, logic 602 and the compliance input may reside on the medical device 102 itself in the same manner as if presented on remote device 104. In yet other embodiments, both devices may include the logic to allow the user full flexibility in providing the compliance input on whichever device is physically closest to the user.

[0045] Figure 7 illustrates one embodiment 700 of a system and method for power management. In this embodiment, logic 702 can provide for one or more sleep timers 704 and associated on/off functions 706. Sleep timer 704 can be used to set a timer for how long medical device 102 operates before automatically shutting down/off. In one embodiment, sleep timer 704 has several possible durations (e.g., 30 minutes, one hour, two hours, etc.) that are input on remote device 104. The input can be via, for example, a sleep timer button that is repeatedly pressed to change the duration of the sleep timer 704. Remote device 104 transmits the sleep timer duration/setting 708 to medical device 102. The sleep timer settings can include a value entered by the user on remote device 104 (which value may also be changed in the same manner) of the duration of the timer after which the medical device 102 will either start or stop operation. Medical device 102 can include similar logic 710 for receiving and implementing the received sleep timer duration/setting 708. Medical device 102 can itself include a similar sleep timer input/button for setting the sleep timer duration without use of remote device 104. In this manner, a user may remotely and/or locally set a sleep timer for medical device 102, which conserves energy and component wear and tear. [0046] Still referring to Figure 7, one embodiment 700 of a system and method for environmental control is illustrated. Remote device 104 includes logic 712 for controlling one or more devices 714 in the environment (e.g., house, room, etc.) of the user. These devices 714 can include, for example, articulating beds (raise, lower, etc.), telephones (answering, dialing, hanging up, etc.), televisions and radios (on/off, channel and volume control, etc.), doors and windows (open, close, lock, etc.), lighting (on, off, dim, etc.), heating/air conditioning (on, off, temperature, etc.), computers/tablets (click, select, enter, mouse control, etc.) and small appliances (on, off, etc.) Remote device 104 can include one or more selector input(s) and logic for selecting which device(s) is to be controlled and one or more additional inputs and logic for controlling the selected device(s) by generating any of the example aforementioned control functions or signals. These inputs can be in the form of, for example, buttons and/or touchscreen menus and inputs. Depressing one or more of these inputs on remote device 104, the logic 712 generates and transmits 716 signals to control device(s) 714. These signals include on/off, increase/decrease, and any of the one or more functions noted above with respect to the example devices listed. In one embodiment, environmental devices 714 have an interface/receiver unit electrically and/or physically connected thereto for receiving the remote control 104 signals and translating them into physical or electrical functions associated with the environmental devices 714. This unit may take form of a wired or wireless receiver having logic to decode the input signal into a target device to control and a control signal. The unit can include relay-type outputs for providing a power control signal and/or digital outputs for providing digital control signals to the target device. This allows the user to control their environmental devices 714 and/or medical devices 102 from a single remote device.

[0047] Figure 8 illustrates one embodiment 800 of a system and method for locating a remote device 104. Remote device 104 can include logic 802 receiving and transmitting lost and found signals 804. In one embodiment, a locating device 810 is used to emit a signal 812 that remote device 104 recognizes as a lost and found search signal. Upon receiving signal 812, logic 802 can generate and respond with audio 806 and/or visual 808 signals in order to assist in physically locating remote device 104. The audio 806 signal can be beep(s), tone(s) or any other audio. The visual signal 808 can be any illuminated display including, for example, flashing, strobing, color, etc. displays. Further yet, logic 802 can generate and transmit an acknowledgment signal 814 indicating remote device 104 has received the lost and found signal 812 from locating device 802. In one embodiment, acknowledgement signal 814 can include GPS information to assist in finding remote device 104. In this manner, when remote device 104 is lost, it can be located.

[0048] Referring now to Figure 9, another embodiment 900 of a system and method for power management is illustrated. Remote device 104 can include logic 902 for conserving battery power. This includes timer logic 904, which sets a timer for putting remote device 104 into a sleep or energy saver mode. Sleep or energy saver mode suspends all nonessential processes/logic within remote device 104 (e.g. biosensor monitoring, GPS updating, user activity/fall sensing (e.g., accelerometer monitoring), etc.)

[0049] Flowever, for example, sleep or energy saver mode does not suspend processes/logic for lost and found (e.g., logic 802, Figure 8), input scanning to “wake” (e.g., such as a random button press to “wake” remote device 104 from sleep or energy mode), and emergency distress signal inputs (e.g., Figs. 1-4), etc. Therefore, remote device 104 does not have to be “awoken” for the lost and found functionality/logic (e.g., Fig. 8) and/or emergency/distress signal logic (e.g., Figs. 1- 4) to be operational. That logic can, but does not have to be, deemed essential so as to not be suspended during sleep or energy saver mode. Other logic too can be deemed essential based on the user’s preferences so as to not be suspended.

[0050] Timer logic 904 can be a repeating background process with a fixed time interval that resets upon any input (e.g., a button depression) provided by the user to remote device 104. For example, the fixed time interval may be 5 minutes (or any other time interval) and is reset each time the user depresses a button or other input on remote device 104. If there is no user input within the 5 minute time interval, logic 904 causes remote device 104 to enter sleep or energy saver mode whereby nonessential processes (e.g., as described above) are suspended.

[0051] Logic 902 can also include sleep logic 906 that allows the user to designate a time period within which remote device 104 will automatically enter sleep or energy saver mode at the expiration thereof. The time period can be any time period such as, for example, 10, 15, 20, 25, 30, etc. minutes. The user can initiate logic 902 upon depression (and/or multiple depression) of a designated button or other input. As described above, when in sleep or energy saver mode, nonessential functions/processes are suspended while others are not. And, as also described above, remote device 104 can be awoken by any user input (e.g., user depression of a button or other input). Hence, logic 902 can conserve and prolong the battery power/source of remote device 104.

[0052] Figure 10 illustrates one embodiment 1000 of a system and method for wirelessly charging remote device 104. Remote device 104 includes, for example, a charging circuit and logic 1002. Charging circuit and logic 1002 include a rechargeable power source 1004 such as, for example, a lithium ion (or similar) battery and a charging coil circuit 1006. Charging coil circuit 1006 uses a coil to convert an electric field into an electric current for charging the power source 1004.

[0053] Medical device 102 also includes a charging coil circuit 1008 for generating an electric field to be received and used by remote device 104 in the wireless charging process. Charging coil circuit 1008 uses a coil to generate an electric field that can be received by charging coil circuit 1006 of remote device 104. Charging coil circuit 1008 obtains power from the power source of medical device 102, which can be either a wall source (e.g., AC) or battery power (e.g., DC) source. The electric field generated by charging coil circuit 1008 induces a current (or flow of electricity) in the charging coil circuit 1006, which is used to charge power source 1004. In this manner, the charging coil of remote 104 and the charging coil of medical device 102 are inductively coupled together allowing transfer of power between the two devices for recharging power sources such as, for example, batteries.

[0054] The system and method 1000 can also include a magnetic coupling arrangement in order to maintain remote device 104 in the proper physical charging position and orientation with respect to the wireless charging location on the external housing of medical device 102. In one embodiment, remote device 104 includes within its housing a metallic (or magnetic) component 1012. Medical device 102 can include within its housing a magnet (or electromagnet) 1010. In operation, as remote device 104 is brought closer to the location of the wireless charging area on the housing of medical device 102, metallic component 1012 will be drawn to magnet 1010 thereby allowing the respective charging coils of each device to be properly aligned and oriented for the wireless charging process. Magnet 1010 can be any shape including circular, segmented (e.g., segmented circle, ellipse, polygon, etc.) linear, etc. Metallic component 1012 can also be of any shape but preferably of complementary shape to magnet 1010. Moreover, the physical charging location on the housing of medical device 102 can be anywhere but preferably in a convenient location easily reachable by the user. This includes, for example, near the control panel (e.g., above, below, to the side thereof, etc.) of medical device 102. On example location is on the top surface of the housing of medical device 102. Further, indicia or markings can be provided thereon to indicate to the user where is the location of the wireless charging station on medical device 102. Further, the wireless charging location on the housing of remote device 104 can be in any location, but preferably in the reverse or backside of the housing to allow close physical contact or proximity with the wireless charging station/location on the housing of medical device 102. In a further embodiment, the charging location can be a pocket formed in the housing that would allow at least partial insertion of the remote device 104 to properly position it for wireless or wired (via a quick connect/disconnect port) charging. The pocket can be located at any convenient location on the housing including front, top and sides thereof.

[0055] Remote device 104 and medical device 102 can further include, for example, circuitry and logic (e.g., 1002) for detecting the presence of a device or electric field suitable for wireless charging purposes and initiating the charging process to the rechargeable power source (e.g., 1004). Further circuitry and logic can be included therein, for example, to monitor and display the progress of the recharging process including displaying the estimated charge of the power source (e.g., percent charged) and to discontinue the recharging process when capacity has been reached in order to not damage the rechargeable power source. This can be displayed on the display(s) of the remote device 104 and/or medical device 102.

[0056] Referring now to Figure 11 , one embodiment of a system and method 1100 for awakening or identifying a medical device 102 is shown. In a warehouse environment, there may be many medical devices 102 stored. And, the respective remote devices 104 may have become physically separated from their respective medical devices. Medical device(s) 102 include logic and circuitry 1104 for awakening when its remote device 104 sends signal 1102. In this manner, a signal from remote device 104 can be used to waken and thereby identify which medical device 102 is associated therewith and the two units can be physically associated again.

[0057] In one embodiment, medical device 102 includes a power source (e.g., battery) 1106, sleep logic 1108, and wake logic 1110. Battery 1106 allows medical device 102 to run in low power mode whereby sleep logic 1108 and wake logic 1110 are active but all other non-essential functions and processes are off. Thus, sleep logic 1108 can be active even though medical device 102 is unplugged for a wall source of power such as when, for example, medical device 102 is at a warehouse. Sleep logic 1108 powers down the medical device 102 into a sleep state, which is not a completely off or powered down state. In one embodiment, sleep logic 1108 monitors for an off signal received either through remote device 104, input on the control panel of medical device 102, or internal sleep timer. When such a signal is received, sleep logic 1108 powers down all non-essential functions and processes as previously described herein.

[0058] Awake logic 1110 is not powered down, but instead repeatedly or continually monitors for receipt of a signal from the remote device 104 that is paired with the medical device 102. Upon receipt of such a signal, awake logic can, for example, light or flash an indicator lamp and/or generate an audio signal identifying which medical device 102, out of a plurality of medical devices 102, are controlled by that particular remote device 104. In other embodiments, awake logic 1110 can fully power on medical device 102 in order to identify medical device 102 from a plurality of such devices. In yet other embodiments, awake logic 1110 can await the receipt of a unique “awake and identify” signal from remote device 104 instead of any input signal. The unique “awake and identify” signal can be generated by a special input (e.g., a uniquely designated button or other input) on remote device 104 if so desired.

[0059] So arranged, a remote device 104 can be used to identify its associated medical device 102 in, for example, a warehouse or storage environment containing a plurality of medical devices 102 (and even a plurality of remote devices) where the remote device may have become physically separated or otherwise unidentifiable with its associated medical device. Each medical device 102 in the plurality in the warehouse can include its own logic and circuitry 1104 for awakening when its remote device 104 sends signal 1102. This allows the two components to be physically associated again without having to replace or re-connect (e.g., pair) a new or different remote device 102 to the medical device 104 to make up for the lost one. [0060] Figure 12 illustrates one embodiment 1200 of a system and method for a remote device 104 acting as a master remote that can communicate with any one or more medical device(s) 104. There may be many situations where a remote device 104 may be lost from its associated medical device 102. In such situations, it may be helpful for a remote device 104 to be able to perform as a master remote device capable of communicating with the medical device whose own remote was lost. In other situations, it may be helpful to have a master remote device 104 capable of communication with any one or more medical device(s) 102. This eliminates the need for having to use each individual remote device for each medical device.

[0061] Still referring to Figure 12, remote device 104 can act as a master remote device communicating 112 with one or more medical devices 1202. Example scenarios where this may be useful include at the manufacturing facility, provider warehouse, institutions (e.g., hospitals, assisted care/living, nursing, etc. facilities.) In these facilities, large numbers of medical devices 1202 may be present and the use of master remote device 104 by medical, technical and/or service professionals can promote efficiency (versus having to locate and use each individual remote device for each individual medical device).

[0062] In one embodiment, remote device 104 includes master logic 1202 that can include, for example, a master key or code. The master key or code can be transmitted 112 to one or more medical devices 102. Logic 1204 within each medical device 102 includes one or more corresponding master codes or keys stored in memory. When a master remote device 104 transmits 112 the master key or code to a medical device 102, medical device 102 compares the key or code to those in its memory. If they match, medical device 102 recognizes master remote device 104 and further receives input, instructions, and/or commands therefrom. Master remote device 104 can include a user input (e.g., button or other input) by which to activate the master key or code function. [0063] In a further embodiment, the master remote device 104 may be programmed to respond to the user that it has detected a corresponding medical device 102 after transmitting a key or master key/code. In the case where the remote device 104 is searching among multiple physical areas (e.g., within a house, medical care facility, warehouse, etc.), or in an area with poor visibility to its contents, or where other occupants are intended to be left undisturbed, the remote device 104 will receive back a confirmation key, code, or message from medical device 102 that it has received the key or code and is present or near. The remote device 104 can then generate a signal or prompt that may be in the from visual, audio, tactile or other forms of feedback to the user of the remote device 104 indicating a medical device 102 has responded and is in the area.

[0064] Further, master remote device 104 can include a selector input that allows the user (e.g., a technician or service person) to select which of the plurality of medical devices 102 are to be controlled by the master remote device. Master remote device 104 can also be a standalone remote device not primarily intended for the user, but for technical and/or service personnel. In other embodiments, master remote device 104 includes the ability to pair with a plurality of medical devices 102 by exchanging pairing codes to valid their communication connection. These unique pairings can be saved in the memory of the master remote device 104 and then, through the selector input described above, any one of such paired medical device(s) can be selected for control. Thus, by any one of a plurality of embodiments, a remote device having a master key or code can be used to control one or more medical devices.

[0065] Figure 13 illustrates one embodiment of a block diagram of a remote device 104. Remote device 104 includes a processing circuit 1302 having a microprocessor capable of executing instructions. A memory or storage circuit 1304 is provided for holding software logic, instructions and data which can be read and stored to by the processing circuit 1302. Remote device 104 can include, but does not need to, one or more sensors 1306 for providing information to the processing unit 1302.

Other sensor devices are intended to fall within the scope of the disclosure according the functions disclosed by the embodiments.

[0068] Figure 14 illustrates one embodiment of a block diagram of a medical device 102. Medical device 102 includes a processing circuit 1404 having a microprocessor capable of executing instructions. A memory or storage circuit 1406 is provided for holding software logic, instructions and data which can be read and stored to by the processing circuit 1404. Medical device 102 also includes one or more input/output devices 1408 and a power/battery circuit 1410 (including components and circuitry for wireless charging and sleep and awake functions as previously disclosed.) Medical device 102 also includes medical device components 1402 for providing therapy or treatment to the user that is under control of processing circuit 1404. In the case of a medical oxygen concentrator, device components 1402 include a gas separation system that separates nitrogen from oxygen and provides the oxygen to a user. Examples of such systems have been described above and incorporated by reference. A medical oxygen concentrator is just one example and other medical device(s) are intended to fall within the scope of the disclosure including, for example, motorized/adjustable beds, CPAP devices, ventilators, etc.

[0069] As previously described herein, one or more input/output devices 1408 can be used by medical device 102.

This listing is not intended to be exhaustive but only illustrative of input/output devices that can be used to accomplish the functions disclosed by the embodiments herein.
