Description

Technical Field

[0001] This application claims priority to U.S. Provisional Application No. 63 / 417,267, filed on October 18, 2022, entitled "AN INFUSION DEVICE HAVING MULTIPLE PUMPING SEGMENTS CONNECTED TO A COMMON FLUID SOURCE AND CONFIGURED TO OPERATE IN PARALLEL WITH EACH OTHER TO PUMP A FLUID FROM THE COMMON FLUID SOURCE".

[0002] The present disclosure generally relates to medical fluid dispensing systems, and more particularly to multiple hand pumps for dispensing medical fluid from an IV bag.

Background Art

[0003] Medical procedures often involve injecting a patient with a medical fluid (e.g., saline or a drug) from an intravenous (IV) bag using an infusion pump. When an infusion pump is not available, medical personnel use their hands to compress or otherwise squeeze the IV bag to administer the medical fluid. Manual compression of the IV bag causes hand fatigue and can be a significant inconvenience to medical personnel.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Therefore, there is a need for a device and method of using the same that can dispense medical fluid from an intravenous (IV) bag to a patient without fatiguing medical personnel.

Means for Solving the Problems

[0005] The subject matter disclosed relates to a plurality of hand pumps for use with an IV set. In a particular implementation, a plurality of hand pumps for use with an IV set is disclosed, the plurality of hand pumps comprising at least two deformable bodies defining an inlet, an outlet, and the volume of a deformable body that fluidly communicates with the inlet and outlet. Each deformable body can be compressed to increase the flow rate of fluid in the IV set.

[0006] In some implementations, an infusion device is disclosed having multiple pumping segments connected to a common fluid source and configured to operate in parallel with each other to pump fluid from the common fluid source. The infusion device includes a first deformable body fluid-coupled between the fluid source and an IV set, the first deformable body being configured to be compressed by the user by hand, and when compressed, to guide a first portion of fluid from the fluid source through the first deformable body to the outlet of the IV set in order to administer fluid to the patient at a first flow rate. The infusion device also includes a second deformable body fluid-coupled between the fluid source and the IV set in parallel with the first deformable body, the second deformable body being configured to be compressed by the user by hand, and when compressed, to guide a second portion of fluid from the fluid source through the second deformable body to the outlet of the IV set in order to administer fluid to the patient at a second flow rate. Multiple pumping segments are configured such that, when compressed according to their respective staggered timing patterns, the first portion of the fluid from the fluid source is delivered from the first pumping segment to the IV set while the second pumping segment is filled with the second portion of the fluid from the fluid source, and the second portion of the fluid from the fluid source is delivered from the second pumping segment to the IV set while the first pumping segment is being filled with the fluid. Examples of multiple hand pumps are described below with reference to Figures 3A to 4C.

[0007] In some implementations, the first deformable body is fluid-connected between the fluid source and the IV set via a first inlet, and the second deformable body is fluid-connected between the fluid source and the IV set via a second inlet. In some implementations, the first and / or second deformable bodies are compressed simultaneously. Alternatively, in some implementations, the first and / or second deformable bodies are compressed in an alternating order. In some implementations, the flow rates of the first and second bodies are the same.

[0008] In some implementations, the injection device further includes one or more filters fluid-coupled to the first and / or second deformable bodies. Each of the filters captures particles from the respective fluids flowing from the first and / or second deformable bodies. In some implementations, when the first and / or second deformable bodies are compressed, the backflow from the first and / or second deformable bodies is directed through one or more filters to agitate the particles captured within the filters. In some implementations, each of the filters is positioned adjacent to the first and / or second inlets of the first and second deformable bodies. In some implementations, each of the filters is positioned within the first and / or second inlets of the first and second deformable bodies. Examples of each of the filters are described below with reference to Figures 3A to 4C.

[0009] In some implementations, the first and second deformable bodies include an elastic material so that they return to an incompressible state. In some implementations, the first and second deformable bodies include a transparent or translucent material. In some implementations, the first and second deformable bodies include a substantially cylindrical shape.

[0010] In a particular implementation, an infusion system is disclosed having multiple pressurizing segments connected to a common fluid source and configured to operate in parallel with each other to pressurize fluid from the common fluid source. The infusion system includes a first portion of a tube, a second portion of a tube, and multiple pressurizing segments configured to operate in parallel. The multiple pressurizing segments include a first deformable body fluid-connected to the first portion of the tube, and a second deformable body fluid-connected to the first portion of the tube. The first deformable body is configured to be compressed by the user by hand, and when compressed, is configured to guide a first portion of fluid from the fluid source from the first deformable body to a fluid-connected outlet in the second portion of the tube to administer fluid to the patient at a first flow rate. The second deformable body is configured to be compressed by the user by hand, and when compressed, is configured to guide a second portion of fluid from the fluid source from the second deformable body to a fluid-connected outlet in the second portion of the tube to administer fluid to the patient at a second flow rate. Multiple pumping segments are configured such that, when compressed according to their respective staggered timing patterns, the first portion of the fluid from the fluid source is delivered from the first pumping segment to the IV set while the second pumping segment is filled with the second portion of the fluid from the fluid source, and the second portion of the fluid from the fluid source is delivered from the second pumping segment to the IV set while the first pumping segment is being filled with the fluid.

[0011] In some implementations, the first and / or second deformable bodies are compressed simultaneously. In some implementations, the first and / or second deformable bodies are compressed in an alternating order. In some implementations, the flow rates of the first and second bodies are the same. In some implementations, the first and second deformable bodies contain elastic material so that they can be restored to an uncompressible state.

[0012] In some implementations, the IV set further includes one or more filters fluid-coupled to the first and / or second deformable body. The one or more filters capture particles from the fluid supplied from the first and / or second deformable body.

[0013] A method is disclosed for forming a device for accelerating fluid from a fluid source to a patient, depending on a particular implementation. The method includes connecting a first deformable body, configured to be compressed by a user by hand, between a first union connector configured to fluidize an upstream infusion line for receiving fluid from a fluid source, and a second union connector located downstream of the first union connector and configured to connect to a downstream infusion line for supplying fluid to an IV set. When compressed, the first deformable body guides a first portion of the fluid from the first deformable body to the IV set to administer a first portion of the fluid to the patient at a first accelerated flow rate. The method includes connecting a second deformable body in parallel with the first deformable body between the first union connector and the second union connector. The second deformable body is configured to be compressed by a user by hand and, when compressed, is configured to guide a second portion of the fluid from the second deformable body to the IV set to administer the fluid to the patient at a second accelerated flow rate. The first and second deformable bodies are configured to work together to deliver fluid from the fluid source to the patient at a flow rate greater than the first and second default flow rates and the default flow rate of the fluid source, by delivering the first portion of the fluid from the first pressurized segment to the IV set while the second pressurized segment is being filled with the second portion of the fluid from the fluid source, and by delivering the second portion of the fluid from the second pressurized segment to the IV set while the first pressurized segment is being filled with the first portion of the fluid from the fluid source, when compressed according to their respective staggered timing patterns.

[0014] In some implementations, the method includes connecting a drip chamber configured to provide a visual indication of the default flow rate of a fluid source upstream of a first coupling connector.

Best Mode for Carrying Out the Invention

[0018] According to convention, the various features shown in the drawings are not drawn to scale. Thus, the dimensions of the various features may be arbitrarily enlarged or reduced for clarity. Additionally, some of the drawings may not illustrate all of the components of a given system, method, or device. Finally, throughout this specification and the drawings, like reference numerals represent like features.

[0019] Many details are set forth in this specification in order to provide a thorough understanding of the exemplary implementations shown in the accompanying drawings. However, some implementations may be practiced without many of the specific details, and the scope of the claims is limited only by the features and aspects specifically recited in the claims. Further, well-known processes, components, and materials have not been described in exhaustive detail in order to avoid obscuring the relevant aspects of the implementations described herein.

[0020] The disclosed plurality of hand pumps are fluidly connected to an IV bag and are configured to accelerate the flow of fluid from the IV bag to a patient for treatment. Specifically, each hand pump of the plurality of hand pumps is configured to deform when compressed (or squeezed). When one of the plurality of hand pumps is compressed, the flow of fluid from the IV bag to the patient increases. Further, the plurality of hand pumps reduces the fatigue felt by a clinician when compressing a hand pump incorporated in a conventional IV set.

[0021] FIG. 1 illustrates an IV pump for administering a medical fluid to a patient. The IV pump 30 includes a controller 32 and one or more pump modules 34. The IV set 20 is connected between a container 36 (e.g., an IV bag) of the medical fluid and the patient 5. During operation, the IV pump 30 delivers the medical fluid to the patient 5. The IV pump 30 is configured to administer the medical fluid to the patient at a predetermined uniform rate. In some implementations, the IV set 20 is utilized to further accelerate the flow of the medical fluid from the container 36 (or the IV pump 30) to the patient. For example, as shown and described below with reference to FIGS. 3A-4C, the IV set 20 can include a plurality of hand pumps that can be used to further accelerate the flow of the medical fluid. Additionally, in some implementations, the plurality of hand pumps are used to agitate any particles trapped within one or more filters (of the IV set 20 and / or the IV pump 30) and increase the flow passing through the filters and the IV set 20. During operation (i.e., during administration of the medical fluid to the patient), the filter can become clogged with particles, potentially reducing the flow through the IV set 20. The filter is configured to prevent the transmission of bacteria, microorganisms, and / or other pathogens. The plurality of hand pumps, as described below with reference to FIGS. 3A-4C, accelerate the flow of the medical fluid and / or agitate any particles trapped within one or more filters by applying a force to the plurality of hand pumps (e.g., squeezing the plurality of hand pumps).

[0022] Figure 2 illustrates a conventional IV set 200. The IV set 200 includes one or more connectors 202, one or more clamps 204 and 208, tubing 206, an infusion chamber 210, a hand pump 220, an infusion site 230, and an outlet port 232. As described above with reference to Figure 1, the IV set 200 delivers fluid from a fluid source, such as a container 36, to the patient 5 via tubing 206. More specifically, the fluid from the fluid source is introduced into a first portion 206-a of the tubing in the IV set 200 and delivered to the patient 5 (e.g., via the flow generated by the IV pump 30 (Figure 1) and / or the hand pump 220). The connector 202 facilitates connection and / or fluid communication between the first portion 206-a of the tubing and the fluid source (e.g., one or more containers 36). More specifically, the connector 202 fluidly connects a first portion 206-a of the tube to one or more containers 36. In some implementations, the connector 202 can be a connector spike that penetrates the membrane of the container 36 to allow fluid communication from the container 36 to the tube 206. Alternatively, in some implementations, the connector 202 can be a needleless connector to avoid accidentally penetrating the membrane when fluidly connecting the first portion 206-a of the tube to the fluid source. In some implementations, the needleless connector can include a no-trip feature to prevent leakage or surface contamination. In some implementations, the needleless connector can further include a Luer lock to prevent accidental discharge. In some implementations, the needleless connector engages with a fluid container that includes a mating connector.

[0023] In some implementations, the second portion 206-b of the tube is connected to the patient 5 via the outlet port 232. Additional medical fluids or treatments may be introduced to the patient via the IV set 200. In some implementations, additional medical fluids or treatments may be introduced into the IV set 200 via the injection site 230. In some implementations, the fluid container allows for the collection of aliquots of blood for analysis.

[0024] Clamps 204 and 208 are configured to control the fluid flow through tube 206 of IV set 200. For example, clamps 204 and 208 can block the fluid flow through tube 206 so that no fluid is distributed to patient 5. Alternatively, clamps 204 and 208 can partially block the fluid flow through tube 206 so that the fluid flow distributed to patient 5 is reduced. Clamps 204 and 208 can be roller clamps, pinch clamps, slide clamps, and / or other clamps known in the art.

[0025] In some implementations, the infusion chamber 210 is formed of a transparent or translucent material to provide a visual indication of the flow rate of the medical fluid passing through it. The infusion chamber 210 is configured so that a clinician and / or other healthcare professional can monitor and adjust the flow rate of the medical fluid based on the visual indication provided by the infusion chamber 210 (e.g., counting the number of drops per second). During operation, the medical fluid can drip or otherwise flow through the chamber volume of the infusion chamber 210. The medical fluid can enter the infusion chamber 210 through an upper or inlet 212 defined within the infusion chamber 210. The inlet 212 is in fluid communication with a first portion 206-a of the tube. The fluid flow exits the infusion chamber 210 through a lower or outlet 214. The outlet 214 can be in fluid communication with a second portion 206-b of the tube. In some implementations, the infusion chamber 210 can equalize the pressure difference between the chamber volume and the environment during operation. In some implementations, the infusion chamber 210 can be formed from an elastic material so that it can be compressed or compressed to draw in medical fluid for priming the IV system. In some implementations, the infusion chamber 210 draws in medical fluid to prime the IV system. As can be understood, during the priming operation, the infusion chamber 210 can be filled with a desired amount of medical fluid.

[0026] In some implementations, the infusion chamber 210 includes a filter for filtering the medical fluid passing through it. In some implementations, the filter 213 is located inside the infusion chamber 210. In some implementations, the filter 213 is located inside the inlet 212 or outlet 214 of the infusion chamber 210. Alternatively, in some implementations, the filter 213 is located within the chamber volume of the infusion chamber 210. In some implementations, the filter 213 is an integrated part of the infusion chamber 210. During operation, the fluid can flow through the inlet 212 of the infusion chamber 210, through the filter 213, and out to the outlet 214 of the infusion chamber 210. As the medical fluid flows through the infusion chamber 210, the fluid can be filtered before flowing out of the infusion chamber 210 and through the second portion 206-b of the tubing. As described above with reference to Figure 1, the fluid in the chamber volume of the infusion chamber 210 passes through the filter 213 to prevent the transmission of bacteria, microorganisms, and / or other pathogens to the patient. As can be understood, a positive pressure difference can guide the fluid flow through the filter 213. As described herein, the filter 213 can selectively filter the flow passing through the infusion chamber 210. The filter 213 may have an average filter opening in the range of 15 to 200 microns. In some implementations, the average filter opening may be in the range of 180 to 200 microns. Optionally, the filter 213 may have pores of different sizes. In some implementations, the filter 213 may be formed from a nonwoven filter material.

[0027] During operation, filter 213 may become clogged with particles, limiting filtration efficiency and flow rate through filter 213. Conventional IV sets 200 may include a hand pump 220 for removing sediment or particles embedded in filter 213, thereby extending the life of filter 213 and increasing flow rate through filter 213. The hand pump 220 can induce backflow or back pressure through filter 213 to remove particles embedded in filter 266. In the illustrated example, a clinician can operate the hand pump 220 to generate backflow through filter 213.

[0028] Figures 3A to 3C illustrate an injection device having multiple pump segments connected to a common fluid source in several implementation configurations. The multiple pump segments of the injection device 300 (e.g., a first deformable body 320-a and a second deformable body 320-b) are configured to operate in parallel with each other to pump fluid from a common fluid source. More specifically, the multiple pump segments are configured to pump a first portion of fluid from the fluid source through the first pump segment to the IV set while the second pump segment is filled with a second portion of fluid from the fluid source, as they are compressed according to their respective staggered timing patterns, and to pump a second portion of fluid from the fluid source through the second pump segment to the IV set while the first pump segment is being filled with fluid. In some implementation configurations, the injection device 300 includes one or more of the features described above with reference to Figure 2. For example, the infusion device 300 includes one or more connectors 202, one or more clamps 204 and 208, a tube 206, an infusion chamber 210, an infusion site 230, and an outlet port 232. The infusion device 300 distributes medical fluid to the patient as described above with reference to Figure 2. The infusion device 300 further includes at least two deformable bodies 320-a and 320-b to accelerate the delivery of fluid to the patient 5 (Figure 1) (i.e., increase the fluid flow) and reduce fatigue of the clinician (or other healthcare worker), thereby enabling the infusion device 300 to be used for extended periods.

[0029] In some implementations, each of the at least two deformable bodies 320-a and 320-b is formed of a transparent or translucent material to provide a visual indication of the flow rate of the fluid passing through it. A clinician (or healthcare professional) can monitor and adjust the fluid flow rate based on the visual indication provided by the at least two deformable bodies 320-a and 320-b. In some implementations, the first deformable body 320-a is fluid-connected between a fluid source (e.g., a container 36, Figure 1) and an IV set or a part thereof (e.g., one or more clamps 208, a tube 206, an injection site 230, and / or an outlet port 232), and the second deformable body 320-b is fluid-connected between the fluid source and the IV set (or a part thereof) in parallel with the first deformable body 320-a. Specifically, the first deformable body 320-a is connected between a first coupling connector 311 configured to fluidize an upstream injection line (e.g., a first portion of the tube 206-a) for receiving fluid from a fluid source, and a second coupling connector 313 located downstream of the first coupling connector 311 and configured to connect to a downstream injection line (e.g., a second portion of the tube 206-b) for supplying fluid to the IV set.

[0030] During operation, the fluid can drip or otherwise flow through the respective deformable volumes 322-a and 322-b of at least two deformable bodies 320-a and 320-b. The fluid can enter at least two deformable bodies 320-a and 320-b through the upper or inlet sections 324-a and 324-b defined by the respective deformable bodies 320-a and 320-b. The inlet sections 324-a and 324-b are in fluid communication with the first section 206-a of the tube. The fluid flow can exit the deformable volumes 322-a and 322-b of at least two deformable bodies 320-a and 320-b through the respective lower or outlet sections 326-a and 326-b. When the respective deformable bodies 320-a and 320-b are not compressed, the fluid, once flow is permitted, exits the deformable body volumes 322-a and 322-b at the first and second default flow rates (e.g., flow rates not accelerated by the compression of the respective deformable bodies). The outlets 326-a and 326-b can be in fluid communication with the second portion 206-b of the tube.

[0031] In some implementations, each of the at least two deformable bodies 320-a and 320-b can be formed from an elastic or deformable material so that at least two deformable bodies 320-a and 320-b can be compressed to draw fluid for priming of the IV system. In addition, in some implementations, each of the at least two deformable bodies 320-a and 320-b is actuated (e.g., compressed) to accelerate the fluid from the deformable body volumes 322-a and / or 322-b to the second portion 206-b of the tube. For example, the first deformable body 320-a is configured to be compressed by the user by hand and, when compressed, is configured to guide a first portion of fluid from a fluid source from the first deformable body to the outlet of the IV set in order to administer the fluid to the patient at a first accelerated flow rate. Similarly, the second deformable body 320-b is configured to be compressed by the user by hand, and when compressed, is configured to guide a second portion of the fluid from the fluid source to the outlet of the IV set from the second deformable body in order to administer the fluid to the patient at a second accelerated flow rate. Those skilled in the art will understand, by reading the description provided herein, that the first deformable body 320-a and the second deformable body 320-b enable the administration of the respective portions of the fluid at first and second flow rates, respectively, without the need for compression (for example, when the fluid is flowing out of the fluid source). Compression of the first deformable body 320-a and the second deformable body 320-b allows the user to adjust the fluid flow rate as needed. In some implementations, the elastic or deformable material includes silicone, rubber, thermoplastic elastomers, plastics, polyurethane, and / or other flexible materials that can be compressed and returned to a stationary state.

[0032] In some implementations, at least two deformable bodies 320-a and 320-b equalize the pressure difference between the deformable body volumes 322-a and 322-b and the environment during operation. In some implementations, the fluid within the deformable body volumes 322-a and / or 322-b is pressurized by reducing the deformable body volumes 322-a and / or 322-b. The pressurized fluid within the deformable body volumes 322-a and / or 322-b is accelerated so that the fluid can be distributed to the user at a faster rate. In some implementations, at least two deformable bodies 320-a and 320-b draw in fluid to prime the IV system. For example, the deformable body volumes 322-a and 322-b can be filled with a desired volume of fluid during the priming operation. Advantageously, the deformable body volumes 322-a and / or 322-b allow at least two deformable bodies 320-a and 320-b to rapidly improve flow through the infusion device 300 while reducing the burden and fatigue of the clinician (or healthcare professional).

[0033] As shown in Figures 3B and 3C, these figures illustrate the compression of at least two deformable bodies 320-a and 320-b. Specifically, Figure 3B illustrates the compression of the first deformable body 320-a, and Figure 3C illustrates the compression of the second deformable body 320-a. In some implementations, at least two deformable bodies 320-a and 320-b are compressed simultaneously. Alternatively, in some implementations, at least two deformable bodies 320-a and 320-b are compressed in an alternating order (for example, the first deformable body 320-a is compressed before the second deformable body 320-a, and vice versa). In some implementations, the flow rates out of each of the at least two deformable bodies 320-a and 320-b are the same (for example, during compression or when no compressive force is applied). Alternatively, in some implementations, the flow rates exiting each of the at least two deformable bodies 320-a and 320-b are different. In some implementations, the flow rates exiting each of the at least two deformable bodies 320-a and 320-b are at least partially based on one or more of the following factors: the material of the at least two deformable bodies 320-a and 320-b, the compressive force applied by the user, the amount of fluid in the deformable body volumes 322-a and 322-b, the pressure in the at least two deformable bodies 320-a and 320-b, and / or other factors.

[0034] In some implementations, each deformable body 320 of at least two deformable bodies 320-a and 320-b contains a filter similar to the filter 213 described above with reference to Figure 2. More specifically, similar to the drip chamber 210, the filters in at least two deformable bodies 320-a and 320-b enable filtration of the fluid passing through them. In some implementations, at least two deformable bodies 320-a and 320-b have built-in filters. In some implementations, due to the larger size and volume of at least two deformable bodies 320-a and 320-b, the filters placed within at least two deformable bodies 320-a and 320-b are larger and have a larger surface area than the filter 213 used in the drip chamber 210. In some implementations, the filters can be of any suitable size. In some implementations, at least two deformable bodies 320-a and 320-b containing filters can be used in place of the filter 213 in the drip chamber 210. Alternatively, in some implementations, at least two deformable bodies 320-a and 320-b, including filters, can be used instead of the infusion chamber 210 (i.e., eliminating the need for additional components of the IV system).

[0035] In some implementations, as the fluid flows through at least two deformable bodies 320-a and 320-b during operation, the fluid is filtered before flowing out of the at least two deformable bodies 320-a and 320-b and into the second portion 206-b of the tube. As described above, the filter prevents the transmission of bacteria, microorganisms, and / or other pathogens to the patient. In some implementations, the filter has an average filter opening in the range of 15 to 200 microns. In some implementations, the average filter opening is in the range of 180 to 200 microns. Optionally, the filter may have pores of different sizes. In some implementations, the filter may be formed from a nonwoven filter material.

[0036] In addition to accelerating the fluid flow, the pressurized fluid in the deformable body volumes 322-a and / or 322-b forces backflow through the filters (similar to the filter 213 described above with reference to Figure 2) of at least two deformable bodies 320-a and 320-b when one of the deformable bodies is operated or compressed, thereby moving or removing particles from the filters. Advantageously, the deformable body volumes 322-a and / or 322-b allow at least two deformable bodies 320-a and 320-b to rapidly improve the flow through the infusion device 300 while reducing the burden and fatigue of the clinician (or healthcare worker).

[0037] Figures 4A to 4C illustrate another infusion device having multiple pressurizing segments connected to a common fluid source, in several implementation configurations. The multiple pressurizing segments of the infusion device 400 (e.g., a first deformable valve body 405-a and a second deformable valve body 405-b connected between a first coupling connector 311 and a second coupling connector 313) are configured to operate in parallel with each other to pressurize fluid from a common fluid source. The infusion device 400 includes one or more features described above with reference to Figures 3A to 3C. For example, the infusion device 400 includes one or more connectors 202, one or more clamps 204 and 208, a tube 206, an infusion chamber 210, an infusion site 230, and an outlet port 232. The infusion device 400 distributes medical fluid to the patient as described above with reference to Figures 3A to 3C. The infusion device 400 further includes at least two deformable valve bodies 405-a and 405-b to accelerate the delivery of fluid to the patient 5 (Figure 1) (i.e., increase fluid flow) and reduce fatigue of the clinician (or other healthcare worker), thereby enabling the infusion device 400 to be used for extended periods. In some implementations, each of the at least two deformable valve bodies 405-a and 405-b includes an inlet 410 that fluid-communicates with a first portion 206-a of the tube, a deformable valve body volume section 430, and an outlet 440 that fluid-communicates with a second portion 206-b of the tube. In some implementations, the first deformable valve body 405-a is fluidly connected between a fluid source (e.g., a container 36, Figure 1) and an IV set or part thereof (e.g., one or more clamps 208, a tube 206, an injection site 230, and / or an outlet port 232), and the second deformable valve body 405-b is fluidly connected between the fluid source and the IV set (or part thereof) in parallel with the first deformable valve body 405-a.

[0038] In some implementations, at least two deformable valve bodies 405-a and 405-b each include a filter 420. In some implementations, at least two deformable valve bodies 405-a and 405-b, including filters, can be used in place of the drip chamber 210. At least two deformable valve bodies 405-a and 405-b are configured to perform similar functions to at least two deformable bodies 220-a and 220-b described with reference to Figures 3A to 3C.

[0039] Each of the at least two deformable valve bodies 405-a and 405-b can generate a higher flow rate (compared to the hand pump 220, Figure 2) when compressed or operated. Furthermore, each of the at least two deformable valve bodies 405-a and 405-b has an ergonomic shape that further reduces clinician fatigue and allows for longer-term use.

[0040] Figures 4B and 4C show the compression of at least two deformable valve bodies 405-a and 405-b. Specifically, Figure 4B shows the compression of the first deformable valve body 405-a, and Figure 4C shows the compression of the second deformable valve body 405-b. In some implementations, at least two deformable valve bodies 405-a and 405-b are compressed simultaneously. Alternatively, in some implementations, at least two deformable valve bodies 405-a and 405-b are compressed in an alternating order (for example, the first deformable valve body 405-a is compressed before the second valve body 405-a, and vice versa). In some implementations, the flow rates exiting each valve body pump of at least two deformable valve bodies 405-a and 405-b are the same (for example, during compression, or when no compressive force is applied). Alternatively, in some implementations, the flow rates exiting each of the at least two deformable valve bodies 405-a and 405-b are different. In some implementations, the flow rates exiting each of the at least two deformable valve bodies 405-a and 405-b are at least partially based on one or more of the following factors: the material of the at least two deformable valve bodies 405-a and 405-b, the compressive force applied by the user, the amount of fluid in the deformable valve body volume 430, the pressure in the at least two deformable valve bodies 405-a and 405-b, and / or other factors.

[0041] Figure 5 is a flowchart showing Method 500 for forming a device for accelerating fluid from a fluid source to a patient in several implementation configurations. Method 500 can be used to form an infusion device including multiple pumping segments, as described above with reference to Figures 3A to 4C. Methods conforming to this disclosure may include at least some, but not all, of the operations shown in Method 500, performed in a different order. Furthermore, methods conforming to this disclosure may include at least two or more steps that are performed temporally overlapping or substantially simultaneously, as in Method 500.

[0042] Method 500 includes the step (502) of connecting a first deformable body (e.g., a first deformable body 320-a or a deformable valve body 405-a, Figures 3A-4C), configured to be compressed by the user by hand, between a first coupling connector 311 (Figures 3A-4C) configured to fluidize an upstream infusion line (e.g., a first portion of a tube 206-a) for receiving fluid from a fluid source, and a second coupling connector 313 (Figures 3A-4C), located downstream of the first coupling connector 311 and configured to connect to a downstream infusion line (e.g., a second portion of a tube 206-b) for supplying fluid to an IV set. The first deformable body, when compressed, is configured to guide a first portion of fluid from the first deformable body to the IV set in order to administer a first portion of fluid to the patient at a first accelerated flow rate. The method further includes the step of connecting a second deformable body (e.g., a second deformable body 320-b or a deformable valve body 405-b, Figures 3A-4C) in parallel with the first deformable body between the first coupling connector 311 and the second coupling connector 313. The second deformable body is configured to be compressed by the user by hand, and when compressed, is configured to guide a second portion of the fluid from the second deformable body to the IV set in order to administer the fluid to the patient at a second accelerated flow rate. Further examples of the first and second deformable bodies are provided above with reference to Figures 3A-4C.

[0043] The first and second deformable bodies are configured to work together to deliver fluid from the fluid source when compressed according to their respective staggered timing patterns, so that fluid is delivered from the fluid source to the patient at a flow rate greater than the first and second default flow rates and the default flow rate of the fluid source (530). In other words, the compression of the first and / or second deformable bodies causes the fluid from the fluid source to flow at a faster rate than when the deformable bodies are uncompressed. Delivering fluid from the fluid source includes delivering a first portion of the fluid from the first pressurized segment (e.g., the first deformable body) to the IV set while the second pressurized segment (e.g., the second deformable body) is filled with a second portion of the fluid from the fluid source (540), and delivering a second portion of the fluid from the second pressurized segment to the IV set while the first pressurized segment is filled with a first portion of the fluid from the fluid source (550). In some implementations, method 500 includes the step of connecting a drip chamber 210 (e.g., Figures 3A–4C) configured to provide a visual indication of the default flow rate of a fluid source upstream of the first coupling connector 311.

[0044] Figure 6 is a conceptual diagram showing an exemplary electronic system 600 for controlling a pump according to an aspect of the present technology. The electronic system 600 may include, but is not limited to, a controller 32 for the IV pump 30, and may be a computing device specifically configured to run software related to the components and processes provided in Figures 1 to 5. The electronic system 600 may be a representative system combined with the disclosures relating to Figures 1 to 5.

[0045] The electronic system 600 may include various types of computer-readable media and interfaces for various other types of computer-readable media. In the illustrated example, the electronic system 600 includes a bus 608, a processing unit 612, system memory 604, read-only memory (ROM) 610, persistent storage device 602, input device interface 614, output device interface 606, and one or more network interfaces 616. In some implementations, the electronic system 600 may include or be integrated with other computing devices or circuits for the operation of the various components and processes described above.

[0046] Bus 608 collectively represents all system buses, peripheral buses, and chipset buses that communicate with numerous internal devices of the electronic system 600. For example, bus 608 communicates with the processing unit 612, the ROM 610, the system memory 604, and the persistent storage device 602.

[0047] The processing unit 612 retrieves instructions to be executed and data to be processed from these various memory units in order to carry out the process of this disclosure. In different implementations, the processing unit may be a single processor or a multi-core processor.

[0048] ROM 610 stores static data and instructions required by processing unit 612 and other modules of the electronic system. On the other hand, persistent storage device 602 is a read / write memory device. This device is a non-volatile memory unit that stores instructions and data even when the electronic system 600 is off. Some implementations of this disclosure use a mass storage device (such as a magnetic disk or optical disk and its corresponding disk drive) as persistent storage device 602.

[0049] Other implementations use a removable storage device (such as a flexible disk, flash drive, and its corresponding disk drive) as the persistent storage device 602. Similar to the persistent storage device 602, the system memory 604 is a read-write memory device. However, unlike the storage device 602, the system memory 604 is volatile read-write memory, such as random-access memory. The system memory 604 stores some of the instructions and data required by the processor at runtime. In some implementations, the process of this disclosure is stored in the system memory 604, the persistent storage device 602, and / or the ROM 610. From these various memory units, the processing unit 612 retrieves the instructions to be executed and the data to be processed in order to execute the process in some implementations. Such storage devices 602 and / or memory devices 604 may be representative of the memory of the controller 32.

[0050] Bus 608 also connects to an input device interface 614 and an output device interface 606. The input device interface 614 allows the user to communicate information and selected commands to the electronic system. Input devices used with the input device interface 614 include, for example, an alphanumeric keyboard and a pointing device (also called a "cursor control device"), such as the one shown in controller 32 in Figure 1. The output device interface 606 (shown as a display in controller 60 in Figure 1, for example) allows the display of images generated by the electronic system 600, for example. Output devices used with the output device interface 606 include, for example, a printer and a display device such as a cathode ray tube (CRT) or liquid crystal display (LCD). Some implementations include devices such as touch screens that function as both input and output devices.

[0051] Furthermore, as shown in Figure 6, bus 608 also connects the electronic system 600 to a network (not shown) via a network interface 616. The network interface 616 may include, for example, a wireless access point (e.g., Bluetooth® or WiFi®) or a wireless circuit for connecting to a wireless access point. The network interface 616 may also include hardware (e.g., Ethernet® hardware) for connecting a computer to a network of computers such as a local area network ("LAN"), a wide area network ("WAN"), a wireless LAN, or an intranet, or a network of networks such as the Internet. Any or all components of the electronic system 600 can be used in conjunction with this disclosure.

[0052] These functions may be implemented in computer software, firmware, or hardware. This technique can be implemented using one or more computer program products. Programmable processors and computers can be included in or packaged as mobile devices. Processes and logic flows can be executed by one or more programmable processors and one or more programmable logic circuits. General-purpose and dedicated computing devices and storage devices can be interconnected via communication networks.

[0053] Some implementations involve electronic components such as microprocessors, storage, and memory that store computer program instructions on machine-readable or computer-readable media (also called computer-readable storage media, machine-readable media, or machine-readable storage media). Some examples of such computer-readable media include RAM, ROM, read-only compact discs (CD-ROM), recordable compact discs (CD-R), rewritable compact discs (CD-RW), read-only digital versatile discs (e.g., DVD-ROM, dual-layer DVD-ROM), various recordable / rewritable DVDs (e.g., DVD-RAM, DVD-RW, DVD+RW, etc.), flash memory (e.g., SD cards, mini-SD cards, micro-SD cards, etc.), magnetic and / or solid-state hard drives, read-only and recordable Blu-ray® discs, ultra-high-density optical discs, any other optical or magnetic media, and flexible discs. Computer-readable media can store computer programs that are executable by at least one processing unit and contain instruction sets for performing various operations. Examples of computer programs or computer code include machine code, such as that generated by a compiler, and files containing high-level code that is executed by a computer, electronic component, or microprocessor using an interpreter.

[0054] The above description primarily refers to microprocessors or multicore processors that run software, but some implementations are performed by one or more integrated circuits, such as application-specific integrated circuits (ASICs) or field-programmable gate arrays (FPGAs). In some implementations, such integrated circuits execute instructions stored within the circuit itself.

[0055] As used herein and in any of the claims, the terms “computer,” “server,” “processor,” and “memory” all refer to specially configured electronic or other technical devices. These terms exclude persons or groups of persons. For the purposes of this specification, the terms “display” or “displaying” mean displaying on an electronic device. As used herein and in any of the claims, the terms “computer-readable medium” and “computer-readable media” are strictly limited to tangible physical objects that store information in a format readable by a computer. These terms exclude wireless signals, wired download signals, and any other transient signals.

[0056] To provide user interaction, the implementations of the subject matter described herein may be implemented on a computer having a display device for displaying information to the user, such as a CRT (cathode ray tube) or LCD (liquid crystal display) monitor, and a keyboard and pointing device, such as a mouse or trackball, on which the user can provide input to the computer. Other types of devices may also be used to provide user interaction; for example, the feedback provided to the user may be any form of sensory feedback, such as visual feedback, auditory feedback, or tactile feedback, and input from the user may be received in any form, including acoustic input, voice input, or tactile input. Furthermore, the computer may interact with the user by sending and receiving documents to and from devices used by the user, for example, by sending a web page to a web browser on the user's client device in response to a request received from a web browser.

[0057] The implementations of the subject matter described herein may be implemented in a computing system that includes back-end components, such as a data server, or middleware components, such as an application server, or front-end components, such as a client computer having a graphical user interface or web browser on which a user can interact with the implementations of the subject matter described herein, or any combination of one or more such back-end components, middleware components, or front-end components. The components of the system may be interconnected by any form or medium of digital data communication, such as a communication network. Examples of communication networks include local area networks ("LANs") and wide area networks ("WANs"), internetworks (e.g., the Internet), and peer-to-peer networks (e.g., ad-hoc peer-to-peer networks).

[0058] A computing system can include clients and servers. Clients and servers are generally geographically separated and may interact via a communication network. The client-server relationship arises from computer programs running on each computer that have a client-server relationship with each other. In some implementations, the server sends data (e.g., an HTML page) to the client device (for example, to display data to a user interacting with the client device and to receive user input from that user). Data generated on the client device (e.g., the results of user interaction) can be received by the server from the client device.

[0059] Those skilled in the art will understand that the various exemplary blocks, modules, elements, components, methods, and algorithms described herein may be implemented as electronic hardware, computer software, or a combination of both. To illustrate this compatibility between hardware and software, various exemplary blocks, modules, elements, components, methods, and algorithms have been generally described above in terms of their functionality. Whether such functionality is implemented as hardware or software depends on the specific application and design constraints imposed on the overall system. The described functionality may be implemented in various ways for each specific application. Without departing entirely from the scope of this art, the various components and blocks may be configured differently (for example, in different orders or divided in different ways).
