TECHNICAL FIELD

The invention relates to a programmable automatic drainage aspiration system comprising a programmable microprocessor, a specially designed PLC, a vacuum motor, a touch screen, a software, a collection container and an incision silicone tube, designed to aspirate the incision related discharges that may occur in the patient after the surgery with a negative pressure system.

BACKGROUND

Drainages in prior art include a silicone reservoir and a silicone or pernous drain tube. These drainage reservoirs are able to exert negative pressure from the incision as a result of compression of the silicon reservoir and provide a qualitative aspiration. This prevents the control of whether there is sufficient negative pressure in the incision line and whether the transfer of the current to the silicon reservoir is provided in sufficient quantity and to make a quantitative observation. Since the pressure exerted by the silicone reservoir on the incision bed is qualitatively adjusted, it is not possible to monitor whether the patient has aspiration at the desired level. Briefly, in the prior art, no quantitative value can be monitored other than the reservoir capacity of the negative pressure incision resistors. Failure to perform these monitoring may cause the patient's length of hospital stay to increase and become infected. Problems may occur in processes such as service density, lack of nurse staff, and non-compliance of the patient with treatment.

BRIEF DESCRIPTION OF THE INVENTION

The invention relates to a programmable automatic drainage aspiration system comprising a programmable vacuum motor, a touch screen, a software, a collection container and an incision silicone tube, designed to aspirate the incision related discharges that may occur in the patient after the surgery with a negative pressure system.

Our device, which is the subject of the invention, can make quantitative negative pressure adjustment and monitoring on the touch screen it comprises. The micro controller system runs the negative pressure motor comprised in the device at the desired level, in a way to ensure that the quantitatively entered negative pressure value is kept constant and shows the value instantly on the device screen. Thanks to the microcontroller system and the negative pressure sensor, the pressure applied to the incision bed can be quantitatively indicated.

The invention shows parameters such as the negative pressure value of the incision line, the amount of incoming exudate flow due to the presence of measurement in the collection container and the treatment time applied via the software, the microcontroller and the negative pressure sensor. The ability to automatically monitor these parameters with software can help shorten the length of hospital stay of the patient and prevent the development of an infection.

DETAILED DESCRIPTION OF THE INVENTION

The invention relates to a programmable automatic drainage aspiration system designed to aspirate the incision related discharges that may occur in the patient after the surgery with a negative pressure system.

The functions of the parts of our invention are listed below.

The Touch screen (1 ): It performs the function of entering the usage parameters and the general use of the device and monitoring the instant operation during the procedures. The parameters entered/edited by the user via the touch screen (1 ) (e.g., negative pressure setting of the device, negative pressure application period, etc.) are transmitted to a microprocessor or the relevant unit. Notifications about the device are shown on this screen.

The Device Jack Input (2): It allows the device to be charged and to connect to electricity.

The On/Off Button (3): It allows the device to be turned on and off.

The Collection Container Slot (4): On the lower part of a front cover (5), it functions as a slot that enables a collection container (13) to be attached to the device and provides a support to the bottom of the collection container (13). The collecting container slot (4) and the collecting container tab (11 ) are attached to each other by a tight fit method. Thus, the probability of the collection container (13) coming off during use is reduced. The Front Cover (5): This part, which forms the front of the device, is made of ABS plastic as a single piece. It further comprises a gap (18.1 ) so that the ultrasonic liquid detection sensor (18) can detect the collected liquid inside the collection container (13). Thanks to this gap, the ultrasonic liquid detection sensor (18) is able to measure the liquid collected in the collection container (13). Thanks to the attachment of the collection container tab (11 ) to the collection container slot (4), the front cover (5) and the collection container (13) are attached to each other by the tight fit method. Thus, the possibility of dislocation of the collection container (13) during use is reduced.

The Collection Container Filter Tab (6): It is the part that provides the filter (21 ) to be mounted on the collecting container (13) fits properly and the surface is perfectly flat.

The Collection Container Placement Sensor (8): It is the sensor that detects whether the collection container (13) is attached by the user's command to run the device. In case the collection container (13) is attached, the circuit is completed by the aforementioned collection container placement sensor (8) (working as a switch) on the collection container (13), and the collection container placement sensor (8) is enabled to detect that the collection container (13) is attached. Thus, thanks to the completed circuit, the device subject to the invention can be operated.

Specially Designed Base (9): As can be seen in Figure 3, the specially designed base (9) of the device is in a "L" form. The purpose of being produced in this form is to minimize the possibility of falling, as there will always be a liquid in the invention. By maximizing the area of the specially designed base (9), the stability is increased and it is ensured that the invention remains in a vertical position even while running. Thus, the user's rate of experiencing problems for this reason is reduced.

A PLC Control Board: PLC control board allows parametric negative pressure sensor calibration thanks to embedded software. Thanks to the pwm control applied to the negative pressure motor, it keeps the pressure range constant with minimal potential difference. PLC embedded software is specially designed to provide electronic communication with touch screen.

The Software: The invention comprises a microprocessor that further comprises the software. The software, within our invention, performs the functions of operating the standard drainage mode and the drainage plus mode and detection of whether the device is disconnected from the patient, whether there is any deformation, tear or breakage on the silicone drainage pipe, the filling rate of the collection container and whether the motor works depending on the battery level.

The Collection Container Tab (11): This part sits to the front cover (5) by means of a tight fit method and acts as a lock.

The Collection Container (13): As a result of negative pressure, the flow coming from the incision line are collected here.

The Collection Container Filter Connection (14): It is a special luerlock connector designed connection point that allows the connection of the filter (22), which serves to prevent the liquid or any substance drawn from the user from escaping into the vacuum pump (22) when it is filled into the collection container (13) thanks to the negative pressure generated by the vacuum pump (22). The feature of this design is that it comprises threads in female form and allows tight fit. The male form on the filter (21 ) fits the mentioned female forms perfectly. Thus, the filter (21 ) is prevented from being displaced involuntarily.

The Silicone Drainage Pipe: It is a medical transfer pipe made of biocompatible material that extends from the silicone drainage pipe outlet port (20) to the user. It is the part that transfers the exudate discharge to the collection container (13) thanks to the negative pressure generated by the vacuum pump (22).

The Negative Pressure Sensor (17): It measures the instantaneous pressure applied by the vacuum pump (22). The data obtained from this is controlled by the software to ensure that the vacuum pump (22) operates continuously at the same negative pressure.

The Ultrasonic Liquid Detection Sensor (18): It qualitatively measures the discharge fill level of the collection container (13). When the level of discharge filled into the collection container (13) reaches the level of the ultrasonic liquid detection sensor (18), it transmits the necessary information to the software and ensures that the process is stopped.

The Ven Valve (19): It is used to connect the vacuum pump (22) to the collection container (13). The mentioned valve allows one-way flow. Thus, the aspirated fluid is not allowed to go back again.

The device, which is the subject of our invention, is brought to the “on” position from the on/off button (3) and started to operate. The touch screen of the device switches to the device control menu and displays the main menu for the operator to make the necessary settings. The device has the feature of working in two different modes.

1. Standard Drainage

2. Drainage Plus

1. Standard Drainage Mode

The vacuum value can be increased by using the up arrow on the touch screen (1 ) comprised in our invention. The vacuum value is also reduced by the down arrow. By selecting these options, the power at which the software will operate the vacuum pump (22) is determined. After the desired value is set, the drainage is activated by pressing the "start drainage" button. Thanks to the touch screen (1 ), the values entered are processed by the microprocessor, and the vacuum pump (22) electronically keeps the negative pressure constant with the data coming from the negative pressure sensor (17). The activated drainage continues to operate the vacuum pump (22) in line with the values from the negative pressure sensor (17) under the control of the microprocessor. When the collection container (13) is full, the ultrasonic liquid detection sensor (18) automatically stops drainage and gives the notification "change the collection container" on the touch screen (1 ).

2. Drainage Plus Mode

The up arrow on the touch screen (1 ) increases the vacuum value. The down arrow reduces the vacuum value. Unlike the standard Drain Mode, waiting times can also be entered in this mode. After setting the desired value by entering the running and waiting times, the drainage is activated by pressing the start drainage button. The value entered via the touch screen (1 ) is processed by the microprocessor to control the operating speed of the vacuum pump (22) and to keep the negative pressure constant thanks to the data from the negative pressure sensor (17). It operates the system by controlling the desired running and waiting times. The activated drainage continues to operate the vacuum motor (22) in line with the values from the negative pressure sensor (17) and under the control of the microprocessor during the running and waiting times entered in the setting menu. When the collection container (13) is full or the container is separated from the device for any reason, the ultrasonic liquid detection sensor (18) or the collection container settling sensor (8) automatically stops drainage and (1 ) displays a "change collection container" notification or a "check collection container" notification on the touch screen.

The charging status of the device is controlled by the microprocessor. When the charge value drops below 10% or if there is no charge left, the user is notified via the touch screen (1 ). The device does not take any action until it is re-plugged into charge or fully charged. This blocking process is provided by the microprocessor in the form of not activating the motor until the required percentage of charge is read.

If the collection container (13) is dislocated, the collection cup placement sensor (8) gives an alert on the touch screen (1) and stops the operation of the device via the microprocessor. The microprocessor prevents the motor from being activated until the collection container (13) is placed.

The invention is connected to the user by a silicone drainage pipe. During use, it has been seen that this silicone drainage pipe is dislocated, deformed, pierced or even broken. For this reason, our invention aims to prevent such incidents that will prevent the device from performing its function. The stable negative pressure that the device provides during normal operation is possible if the silicone drainage pipe is connected to the user. Because if a hole or tear is formed on the silicone drainage pipe or it is separated from the user's body, our invention cannot find an area where the desired negative pressure will be applied. For this reason, negative pressure that cannot be kept constant and applied indicates that there is a problem in the working environment. At this point, the software, based on the data it receives from the negative pressure sensor (17), starts to control the pressure continuously at 1 -minute intervals due to the negative pressure cannot be kept constant or the normal pressure course is disturbed. This control is to check whether the data from the negative pressure sensor (17) begins to normalize. When the continuity of the pressure loss is detected, it notifies the user via the touch screen (1 ) to check the silicone drainage pipe.

When the collection container (13) is full, the ultrasonic liquid detection sensor (18) transmits the necessary information to the microprocessor, automatically stops the drainage and gives the “replace collection container” warning on the touch screen (1 )-
