CROSS-REFERENCE TO RELATED APPLICATION

[0001] The present application claims priority to United States Provisional Application Serial No. 63/338,677, entitled “Actuator Actuated Valves for Maintaining Multi-Lumen Patency and Method for Pulsatile Flow Lumen Flushing”, filed May 5, 2022, the entire disclosure of which is hereby incorporated by reference in its entirety.

BACKGROUND

1. Field

[0002] The present disclosure relates generally to a fluid delivery and, in some nonlimiting embodiments or aspects, to actuator actuated valves for maintaining multilumen patency and/or a method for pulsatile flow IV line flushing.

2. Technical Considerations

[0003] There is an increasing clinical need for patients to have dual or triple lumen IV catheters. These multi-lumen catheters are used to deliver multiple IV medication infusions to a patient at the same time in situations where the medications cannot be mixed together until the medications are in the blood stream of the patient. These multi-lumen IV catheters are often kept in-dwelling in the patient for weeks or months. During this in-dwelling time, the multiple medication infusions may only be delivered periodically for relatively short durations. For the remainder of the in-dwelling time, only a single IV medication infusion (or no medication infusion) may be delivered. However, for these times when only a single medication infusion (or no medication infusion) is being delivered, there is a challenge in keeping the unused catheter lumens patent (e.g., open, etc.) because catheter lines may tend to occlude (e.g., become block, etc.) due to various biological responses in the patient over long periods of time between active flow in the lumens. Existing solutions for this challenge are not ideal because a clinician has to flush the unused lumen(s) with saline and/or multiple IV drip bags, even if the patient is already receiving the one IV medication infusion.

[00153] For purposes of the description hereinafter, the terms “upper”, “lower”, “right”, “left”, “vertical”, “horizontal”, “top”, “bottom”, “lateral”, “longitudinal”, and derivatives thereof shall relate to the invention as it is oriented in the drawing figures. However, it is to be understood that the invention may assume various alternative variations, except where expressly specified to the contrary. It is also to be understood that the specific devices illustrated in the attached drawings, and described in the following specification, are simply exemplary aspects of the invention. Hence, specific dimensions and other physical characteristics related to the aspects disclosed herein are not to be considered as limiting. All numbers and ranges used in the specification and claims are to be understood as being modified in all instances by the term “about”. By “about” is meant plus or minus twenty-five percent of the stated value, such as plus or minus ten percent of the stated value. However, this should not be considered as limiting to any analysis of the values under the doctrine of equivalents.

[00154] Unless otherwise indicated, all ranges or ratios disclosed herein are to be understood to encompass the beginning and ending values and any and all subranges or sub-ratios subsumed therein. For example, a stated range or ratio of “1 to 10” should be considered to include any and all subranges or sub-ratios between (and inclusive of) the minimum value of 1 and the maximum value of 10; that is, all subranges or sub-ratios beginning with a minimum value of 1 or more and ending with a maximum value of 10 or less. The ranges and/or ratios disclosed herein represent the average values over the specified range and/or ratio.

[00155] The terms “first”, “second”, and the like are not intended to refer to any particular order or chronology, but refer to different conditions, properties, or elements. [00156] No aspect, component, element, structure, act, step, function, instruction, and/or the like used herein should be construed as critical or essential unless explicitly described as such. Also, as used herein, the articles “a” and “an” are intended to include one or more items, and may be used interchangeably with “one or more” and “at least one.” Furthermore, as used herein, the term “set” is intended to include one or more items (e.g., related items, unrelated items, a combination of related and unrelated items, etc.) and may be used interchangeably with “one or more” or “at least one.” Where only one item is intended, the term “one” or similar language is used. Also, as used herein, the terms “has,” “have,” “having,” or the like are intended to be open-ended terms.

Thus, the operation and behavior of the systems and/or methods are described herein without reference to specific software code, it being understood that software and hardware can be designed to implement the systems and/or methods based on the description herein.

[00159] Some non-limiting embodiments or aspects are described herein in connection with thresholds. As used herein, satisfying a threshold may refer to a value being greater than the threshold, more than the threshold, higher than the threshold, greater than or equal to the threshold, less than the threshold, fewer than the threshold, lower than the threshold, less than or equal to the threshold, equal to the threshold, etc.

[00160] As used herein, the term “computing device” or “computer device” may refer to one or more electronic devices that are configured to directly or indirectly communicate with or over one or more networks. The computing device may be a mobile device, a desktop computer, or the like. Furthermore, the term “computer” may refer to any computing device that includes the necessary components to receive, process, and output data, and normally includes a display, a processor, a memory, an input device, and a network interface. An “application” or “application program interface” (API) refers to computer code or other data sorted on a computer-readable medium that may be executed by a processor to facilitate the interaction between software components, such as a client-side front-end and/or server-side back-end for receiving data from the client. An “interface” refers to a generated display, such as one or more graphical user interfaces (GUIs) with which a user may interact, either directly or indirectly (e.g., through a keyboard, mouse, touchscreen, etc.).

[00161] Non-limiting embodiments or aspects of the present disclosure may provide a rotary actuator (e.g., a servo, etc.) and/or a linear actuator actuated valve for maintaining multi-lumen IV catheter patency that improves multi-lumen IV catheter patency during Keep Vein Open (KVO) saline infusion and/or single medication and/or lumen infusion applications. Non-limiting embodiments or aspects of the present disclosure may enable diverting saline and/or medication flow from a single input (e.g., an IV Bag, an IV pump, a syringe, etc.) to two or more IV Catheter lumens by using a servo actuated fluid diverter manifold configured to switch incoming fluid flow to two or more output ports, which enables a clinician to ensure that each catheter lumen is receiving flow, which may be necessary to maintain patency, without additional flushing or IV maintenance. Non-limiting embodiments or aspects of the present disclosure may enable diverting saline and/or medication flow from a plurality of inputs to a single output of a plurality of outputs, which likewise enables a clinician to individually ensure that each catheter lumen is receiving flow, while avoiding a scenario in which a fluid flow is not equally distributed between multiple flow channels due to a higher flow being directed to a lumen with the least restriction.

[00162] Referring to FIGS. 1 A-1 G, actuator actuated valve 100 (e.g., a rotary actuator actuated diverter valve, etc.) for maintaining multi-lumen patency may include valve manifold 102, valve spool 108, actuator 1 10 (e.g., a rotary actuator, etc.), and/or housing 120.

[00163] Valve manifold 102 may include an input port 104, a first output port 106a, and/or a second output port 106b. [00164] Valve spool 108 may extend within the valve manifold. Valve spool 108 may define first valve passageway 103a and second valve passageway 103b. Valve spool 108 may be rotatable relative to valve manifold 102 between a first position in which input port 104 and first output port 106a are in fluid communication via first valve passageway 103a (e.g., as shown in FIG. 1 B) and a second position in which the input port 104 and second output port 106b are in fluid communication via second valve passageway 103b (e.g., as shown in FIG. 1 C).

[00165] Rotary actuator 1 10 may be configured to rotate valve spool 108 relative to valve manifold 102 between the first position and the second position. For example, rotary actuator 110 may include a servomotor. As an example, an end of valve spool 108 may include an actuator interface 1 1 1 configured to interface with rotatory actuator 1 10 (e.g., a complementary mechanical mating, etc.).

[00166] In some non-limiting embodiments or aspects, when valve spool 108 is between the first position and the second position, input port 104 is not in fluid communication with first output port 106a and second output port 106b. For example, when valve spool 108 is transitioning in-between positions, valve spool 108 may block fluid flow (e.g., break before make, etc.) from first output port 106a and second output port 106b.

[00167] In some non-limiting embodiments or aspects, when valve spool 108 is between the first position and the second position, input port 104 is in fluid communication with each of first output port 106a and second output port 106b. For example, when valve spool 108 is transitioning in-between positions, valve spool 108 may allow fluid flow (e.g., make before break, etc.) from first output port 106a and second output port 106b.

[00168] In some non-limiting embodiments or aspects, valve spool 108 is rotatable relative to valve manifold 102 between the first position, the second position, and a third position in which input port 104 is not in fluid communication with first output port 106a and second output port 106b.

[00169] In some non-limiting embodiments or aspects, when valve spool 108 is in the first position, input port 104 is not in fluid communication with second output port 106b, and, when valve spool 108 is in the second position, input port 104 is not in fluid communication with first output port 106a. [00170] In some non-limiting embodiments or aspects, valve manifold 102 further includes at least one further output port 106n, valve spool 108 further defines at least one further valve passageway 103n, valve spool 108 is further rotatable relative to valve manifold 102 between the first position, the second position, and at least one further position in which in input port 104 and the at least one further output port 106n are in fluid communication via the at least one further valve passageway 103n (e.g., as shown in FIGS. 1 E-1 G). For example, valve spool 108 may be rotatable between a plurality of positions, wherein, in the plurality of positions, (i) a single output port of the plurality of output ports 106a, 106b, 106n is in fluid communication with input port 104 via a single valve passageway and (ii) the other output ports of the plurality of output ports 106a, 106b, and 106n are not in fluid communication with the input port 104 via the other valve passageways.

[00171] In some non-limiting embodiments or aspects, a first check valve is integrated with and/or connected to first output port 106a, and a second check valve is integrated with second output port 106b. For example, one or more check valves may be integrated with and/or connected to one or more output ports of valve manifold 102.

[00172] In some non-limiting embodiments or aspects, input port 104 is removably connected to a fluid output of fluid reservoir 150. In some non-limiting embodiments or aspects, input port 104 is integrated with a fluid output of fluid reservoir 150 (e.g., as shown in FIGS. 1 E and 1 F). For example, input port 104, valve manifold 102, and/or output ports 106a, 106b, 106n may be integrated with (e.g., permanently connected to, molded as a single piece with, etc.) fluid reservoir 150 (e.g., with a tip of a syringe, etc.).

[00173] As shown in FIG. 1 D, housing 120 may include actuator 1 10, controller 122, communication device 124, user feedback device 126, power source 128, and/or memory 130. For example, housing 120 may be attached to (e.g., removably attached to, integrated with, etc.) valve spool 108. In some non-limiting embodiments or aspects, housing 120 (and/or its included components) is a reusable housing that is configured to be attached to and used with a first valve manifold 102 and valve spool 108 combination, removed from the first valve manifold 102 and valve spool 108 combination after use, and subsequently attached to and used with a different valve manifold 102 and valve spool 108 combination. In some non-limiting embodiments or aspects, housing 12 (and/or its included components) may be a disposable housing that is configured to be disposed of with valve manifold 102 and valve spool 108 combination after a single use. In some non-limiting embodiments or aspects, housing 120 may include a housing of an infusion pump.

[00174] Controller 122 may be programmed and/or configured to control, based on control data, rotary actuator 1 10 to rotate valve spool 108 relative to valve manifold 102 between the first position and the second position. In some non-limiting embodiments or aspects, processor 124 may include a low power microcontroller unit (MCU). Controller 122 may store information associated with a position of valve spool 108 in memory 130.

[00175] Communication device 124 may be configured to communicate with an external computing device (e.g., infusion pump 202, etc.). For example, communication device 124 may be configured to receive control data from the external computing device, the control data including program instructions, which when executed by controller 122, cause controller 122 to control rotary actuator 1 10 in accordance with the program instructions. In some non-limiting embodiments or aspects, communication device 124 may include a wired communication configured to receive the control data from the external computing device via a wired connection.

[00179] Referring now to FIGS. 6A and 6B, and still referring to FIG. 1 D, an actuator actuated valve 600 for maintaining multi-lumen patency may include valve body 602, a plurality of flexible membranes 605a, 605b, 605n, actuator 610 (e.g., a linear actuator, etc.), and/or housing 620.

[00180] Valve body 602 may include a plurality of valve passageways 603a, 603b, 603n extending between a plurality of input ports 604a, 604b, 604n, a plurality of output ports 606a, 606b, 606n.

[00181] The plurality of flexible membranes 605a, 605b, 605n may define a portion of the plurality of valve passageways 603a, 603b, 603n. Each flexible membrane of the plurality of flexible membranes 605a, 605b, 605n (i) may include a first face that faces a valve passageway of the plurality of valve passageways 603a, 603b, 603n and a second face opposite the first face and (ii) may be configured for movement with respect to the valve passageway in response to a force applied to the second face of that flexible membrane to form a barrier against a flow of fluid in the valve passageway. For example, and referring specifically toe FIG. 6B, flexible membrane 605b may be configured to move inward toward an opposite wall of fluid passageway 603b and/or toward output port 604b (e.g., in a fluid passageway structure in an ‘L’ shape or right angle as shown in FIG. 6B, to contact or form a seal with the opposite wall of fluid passageway 603b and/or to plug output port 604b to form a barrier against the flow of fluid in valve passageway 603b.

[00182] Linear actuator 610 may be configured to apply a force to the second face of each flexible membrane of the plurality of flexible membranes 605a, 605b, 605n to form the barrier against the flow of fluid in the valve passageway of that flexible membrane.

[00183] As shown in FIG. 1 D, housing 620 may include the same or similar component as housing 120 (e.g., controller 122, communication device 124, user feedback device 126, power source 128, memory 130, etc.) and actuator 610 (e.g., a linear actuator, etc.) instead of actuator 1 10. A discussion of the same or similar components and their functions is not repeated in the interest of brevity. In such an example, communication device 124 may be configured to receive control data from an external computing device, and/or controller 122 may be configured to control, based on the control data, linear actuator 610 between a plurality of positions in which the force is applied to one or more flexible membranes of the plurality of flexible membranes 605a, 605b, 605n to form the barrier against the flow of fluid in one or more valve passageways of the plurality of valve passageways 603a, 603b, 603n. In some non-limiting embodiments or aspects, housing 620 may include a housing of an infusion pump.

[00184] In some non-limiting embodiments or aspects, in the plurality of positions, (i) linear actuator 610 does not apply the force to the second face of a single flexible membrane of the plurality of flexible membranes 605a, 605b, 605n to allow the flow of fluid in a single fluid passageway of the plurality of fluid passageways 603a, 603b, 603n and/or (ii) the linear actuator applies the force to the second face of the other flexible membranes of the plurality of flexible membranes 605a, 605b, 605n to form the barrier against the flow of fluid in the other valve passageways of the plurality of valve passageways 603a, 603b, 603n. For example, if controller 122 controls linear actuator 610 to not apply the force to the second face of flexible membrane 605b to allow the flow of fluid in fluid in valve passageway 603b, controller 122 may control linear actuator 610 to apply the force to the second faces of flexible membranes 605a and 605n to form the barrier against the flow of fluid in valve passageways 603a and 603n, thereby enabling fluid flow from a plurality of inputs to a single output of a plurality of outputs while avoiding a scenario in which a fluid flow is not equally distributed between multiple flow channels due to a higher flow being directed to a lumen with the least restriction.

[00185] In some non-limiting embodiments or aspects, a plurality of check valves is connected to and/or integrated with the plurality of output ports 606a, 606b, 606n.

In some non-limiting embodiments or aspects, the plurality of input ports 604a, 604b, 604n is integrated with (e.g., permanently connected to, formed or molded as a single piece with, etc.) a plurality of fluid outputs of fluid reservoir 650 (e.g. an IV bag, an infusion pump, a syringe, etc.). For example, fluid reservoir 650 may include a syringe, and the plurality of input ports 604a, 604b, 604n may be removably connected to or integrated with a plurality of tips of the syringe. In some non-limiting embodiments or aspects, a multilumen catheter including a plurality of lumens is connected to the plurality of output ports 606a, 606b, 606n.

[00187] Referring now to FIGS. 7A-7C, and still referring to FIG. 1 D, an actuator actuated valve 700 for maintaining multi-lumen patency may include plate 702 (e.g., a rigid plate, a base, etc.), a plurality of flexible tubes 707a, 707b, 707n, cam shaft 705, actuator 710 (e.g., a rotary actuator, etc.), and/or housing 720.

[00188] The plurality of flexible tubes 707a, 707b, 707n may include a plurality of valve passageways 703a, 703b, 703n extending between a plurality of input ports 704a, 704b, 704n and a plurality of output ports 706a, 706b, 706n. The plurality of input ports 704a, 704b, 704n may be configured to be connected to a plurality of fluid outputs of fluid reservoir 750. For example, the plurality of input ports 704a, 704b, 704n may removably connected to the plurality of fluid outputs of fluid reservoir 750. As an example, the plurality of input ports 704a, 704b, 704n may be integrated with the plurality of fluid outputs of the fluid reservoir.

[00189] Plate 702 may include a plurality of guide walls 709 spaced apart from each other and extending from plate 702.

For example, the plurality of flexible tubes 707a, 707b, 707n may be press fit in the plurality of guide tracks between the pairs of the plurality of guide walls 709.

[00190] Cam shaft 705 may include a plurality of cams 708a, 708b, 708n.

[00191] In some non-limiting embodiments or aspects, in the plurality of positions, (i) a single cam of the plurality of cams 708a, 708b, 708n does not pinch a single flexible tube of the plurality of flexible tubes 707a, 707b, 707n against plate 702 to allow the flow of fluid in a single fluid passageway of the plurality of fluid passageways 703a, 703b, 703n and (ii) the other cams of the plurality of cams 708a, 708b, 708n press the other flexible tubes of the plurality of flexible tubes 707a, 707b, 707n against plate 702 to form barriers against the flow of fluid in the other fluid passageways of the plurality of fluid passageways 703a, 703b, 703n. For example, when cam 708n does not pinch flexible tube 707n against plate 702 to allow the flow of fluid in fluid passageway 703a, cams 708a and 708b may press flexible tubes 707a and 707b against plate 702 to form barriers against the flow of fluid in fluid passageways 703a and 703b, thereby enabling fluid flow from a plurality of inputs to a single output of a plurality of outputs while avoiding a scenario in which a fluid flow is not equally distributed between multiple flow channels due to a higher flow being directed to a lumen with the least restriction.

For example, and referring specifically to FIG. 7C, a sidewall of the housing of the infusion pump 720 may include plate 702 including the plurality of guide walls 709 defining the plurality of guide tracks. In such an example, infusion pump may include a rotary actuator mechanism (e.g., actuator 710 and cam shaft 705, etc.) and/or a linear actuator (e.g., actuator 610, etc.) configured to pinch one or more flexible tubes of the plurality of flexible tubes 707a, 707b, 707n at least one of against plate 702 and against the guide walls 709 to form a barrier against a flow of fluid in one or more fluid passageways of the plurality of fluid passageways 703a, 703b, 703n

[00195] In some non-limiting embodiments or aspects, the plurality of input ports 704a, 704b, 704n is removably connected to a plurality of fluid outputs of fluid reservoir 750 (e.g. an IV bag, an infusion pump, a syringe, etc.). In some non-limiting embodiments or aspects, the plurality of input ports 704a, 704b, 704n is integrated with (e.g., permanently connected to, formed or molded as a single piece with, etc.) a plurality of fluid outputs of fluid reservoir 750 (e.g. an IV bag, an infusion pump, a syringe, etc.). For example, fluid reservoir 750 may include a syringe, and the plurality of input ports 704a, 704b, 704n may be removably connected to or integrated with a plurality of tips of the syringe. In some non-limiting embodiments or aspects, a multilumen catheter including a plurality of lumens is connected to the plurality of output ports 706a, 706b, 706n.

As shown in FIG. 2, environment 200 may include infusion pump 202, actuator actuated valve 100, 600, and/or 700, and/or catheter 204 (e.g., a single lumen catheter, a multi-lumen catheter, etc.). For example, a system for maintaining multi-lumen patency may include infusion pump 202, actuator actuated valve 100, 600, and/or 700, and/or catheter 204. As an example, catheter 204 may include a multilumen catheter, and the multi-lumen catheter may include two or more lumens connected at first ends to two or more output ports 106a, 106b of valve manifold 102 (e.g., a first lumen connected to first output port 106a, a second lumen connected to the second output port 106b, etc.), to two or more output ports 606a, 606b, 606n of valve body 602, and/or two or more output ports 706a, 706b, 706n of flexible tubes 707a, 707b, 707n, and connected at seconds ends to a patient.

[00198] Referring now to FIG. 3, FIG. 3 is a diagram of example components of a device 300. Device 300 can correspond to one or more devices of housing 120, 620, and/or 702 and/or one or more devices of infusion pump 202. In some non-limiting embodiments or aspects, one or more devices of housing 120, 620, and/or 720 and/or one or more devices of infusion pump 202 can include at least one device 300 and/or at least one component of device 300.

[00199] Bus 302 includes a component that permits communication among the components of device 300. In some non-limiting embodiments or aspects, processor 304 is implemented in hardware, firmware, or a combination of hardware and software. For example, processor 304 includes a processor (e.g., a central processing unit (CPU), a graphics processing unit (GPU), an accelerated processing unit (APU), etc.), a microprocessor, a digital signal processor (DSP), and/or any processing component (e.g., a field-programmable gate array (FPGA), an application-specific integrated circuit (ASIC), etc.) that can be programmed to perform a function.

For example, communication interface 314 includes an Ethernet interface, an optical interface, a coaxial interface, an infrared interface, a radio frequency (RF) interface, a universal serial bus (USB) interface, a Wi-Fi interface, a cellular network interface, and/or the like.

[00203] Device 300 can perform one or more processes described herein. Device 300 can perform these processes based on processor 304 executing software instructions stored by a computer-readable medium, such as memory 306 and/or storage component 308.

Additionally, or alternatively, hardwired circuitry can be used in place of or in combination with software instructions to perform one or more processes described herein. Thus, embodiments described herein are not limited to any specific combination of hardware circuitry and software.

[00205] The number and arrangement of components shown in FIG. 3 are provided as an example. In some non-limiting embodiments or aspects, device 300 includes additional components, fewer components, different components, or differently arranged components than those shown in FIG. 3. Additionally, or alternatively, a set of components (e.g., one or more components) of device 300 can perform one or more functions described as being performed by another set of components of device 300. [00206] Referring now to FIG. 4, FIG. 4 is a flowchart of non-limiting embodiments or aspects of a process 400 for pulsatile flow IV line flushing. In some non-limiting embodiments or aspects, one or more of the steps of process 300 may be performed (e.g., completely, partially, etc.) by infusion pump 202 (e.g., one or more devices of a system of infusion pump 202, etc.). In some non-limiting embodiments or aspects, one or more of the steps of process 300 may be performed (e.g., completely, partially, etc.) by another device or a group of devices separate from or including infusion pump 202, such as an computing system in communication with infusion pump 202 (e.g., one or more devices of a computing system in communication with infusion pump 202).

[00207] As shown in FIG. 4, at step 402, process 400 includes measuring a baseline fluid pressure. For example, infusion pump 202 may measure a baseline fluid pressure of an IV catheter line (e.g., an IV catheter line or lumen of catheter 204, etc.) connected to infusion pump 202 and a patient. As an example, infusion pump 202 may measure the baseline fluid pressure when a flow rate of a fluid through the IV catheter line is zero. For example, infusion pump 202 may measure and store a fluid pressure value from of the IV catheter line (e.g., typically 1.5 psi, etc.), using a fluid pressure sensing device that is incorporated in infusion pump 202, when infusion pump 202 is not flowing or pumping fluid through the IV catheter line. In such an example, infusion pump 202 may be primed and connected to the IV catheter line of catheter 204 before measuring the baseline fluid pressure of the IV catheter line.

[00208] In some non-limiting embodiments or aspects, if the measured baseline fluid pressure is measured as greater than a threshold baseline fluid pressure, infusion pump 202 sets a value of the measured baseline fluid pressure as the threshold baseline fluid pressure for determining a predetermined delta pressure setting above the measured baseline fluid pressure. For example, infusion pump 202 may limit the baseline fluid pressure to a maximum safety pressure (e.g., 2.0 psi, etc.).

[00209] As shown in FIG. 4, at step 404, process 400 includes increasing a flow rate until a current fluid pressure is a predetermined delta above a baseline fluid pressure. For example, and referring also to FIG. 5, which is a graph 500 illustrating steps of stages of non-limiting embodiments or aspects of process 400 for pulsatile flow IV line flushing, infusion pump 202 may increase the flow rate of the fluid through the IV catheter line until a current pressure of the IV catheter line satisfies a predetermined delta pressure setting (e.g., 3.0 psi, etc.) above the measured baseline fluid pressure (e.g., a sum of the predetermined delta pressure setting and the measured baseline fluid pressure, etc.).

[00210] In some non-limiting embodiments or aspects, infusion pump 202 linearly increases the flow rate of the fluid through the IV catheter line until the current pressure of the IV catheter line satisfies the predetermined delta pressure setting above the measured baseline fluid pressure.

[00211] In some non-limiting embodiments or aspects, infusion pump 202 controls the flow rate of the fluid through the IV catheter line to remain at or below a safety threshold flow rate. For example, if the flow rate, which may be measured by a flow sensor of infusion pump 202 or an external flow sensor inline and/or attached to catheter 204, reaches a predetermined safety limit (e.g., 2 mL/s for a pulsatile flow, etc.), infusion pump 202 may not further increase the flow rate beyond the predetermined safety limit (e.g., even if the current pressure of the IV catheter line does not satisfy the predetermined delta pressure setting above the measured baseline fluid pressure, etc.).

[00212] As shown in FIG. 4, at step 406, process 400 includes controlling a flow rate to maintain a current fluid pressure at a predetermined delta above a baseline fluid pressure until a predetermined pulsatile flow volume is infused. For example, and referring also to FIG. 5, in response to the current pressure of the IV catheter line satisfying the predetermined delta pressure setting above the measured baseline fluid pressure, infusion pump 202 may control, based on the current pressure of the IV catheter line, the flow rate of the fluid through the IV catheter line to maintain the current pressure of the IV catheter line at the predetermined delta pressure setting above the baseline fluid pressure until a predetermined pulsatile flow volume (e.g., 1 ml for a pulsatile flow, etc.) is infused through the IV catheter line. As an example, infusion pump 202 may adjust the flow rate of the fluid through the IV catheter line via a closed loop control process (e.g., based on the measured flow rate and/or pressure, etc.) to maintain the current pressure in the IV catheter line at the predetermined delta pressure setting above the measured baseline fluid pressure until the predetermined pulsatile flow volume is infused through the IV catheter line. [00213] As shown in FIG. 4, at step 408, process 400 includes decreasing a flow rate of a fluid until the flow rate is zero. For example, and referring also to FIG. 5, in response to the predetermined pulsatile flow volume being infused into the IV catheter line, infusion pump 202 may decrease the flow rate of the fluid through the IV catheter line until the flow rate is zero.

[00214] In some non-limiting embodiments or aspects, infusion pump 202 linearly decreases the flow rate of the fluid through the IV catheter line until the flow rate is zero.

[00215] As shown in FIG. 4, at step 410, process 400 includes maintaining a flow rate of a fluid at zero for a predetermined period of time. For example, and referring also to FIG. 5, in response to decreasing the flow rate of the fluid through the IV catheter line to zero, infusion pump 202 may maintain the flow rate of the fluid through the IV catheter line at zero for a predetermined period of time (e.g., 0.5 s for a pulsatile flow, etc.).

[00216] As shown in FIG. 4, at step 412, process 400 includes determining whether a predetermined total flush volume is infused. For example, infusion pump 202 may determine whether a predetermined total flush volume is infused. As an example, infusion pump 202 may determine, using the measured flow rate and time and/or a measured volume delivered, whether a predetermined total flush volume has been infused through the IV catheter line.

[00217] In response to determining in step 412 that the predetermined total flush volume is infused in step 412, process 400 may return to step 404. For example, and referring also to FIG. 5, in response to determining in step 412 that the predetermined total flush volume is infused, infusion pump 202 may return processing to step 404 and increase the flow rate of the fluid through the IV catheter line until a current pressure of the IV catheter line satisfies a predetermined delta pressure setting above the measured baseline fluid pressure.

[00218] In response to determining in step 412 that the predetermined total flush volume is infused, the process 400 for pulsatile flow IV line flushing may end. For example, in response to determining in step 412 that the predetermined total flush volume is not infused, infusion pump 202 may end the process 400 for pulsatile flow IV line flushing.
