Description

Technical Field

[0001] The present disclosure relates generally to intravenous (IV) sets and, more particularly, to syringe couplings and reusable drivers for rapid infusion via an IV set. Background Art

[0002] Medical treatments often include infusing medical fluids (e.g., medications, saline solutions) into a patient using an IV catheter that is connected to a fluid source, such as an IV bag, by an arrangement of flexible tubing and fittings commonly referred to as an "IV set." During surgery, it may be necessary to quickly replenish medical fluids and additional medications at a substantially increased flow rate, as shortening medical treatment time is often associated with reducing the risk of death in trauma patients. In addition, some medical fluids may be highly viscous, making it difficult to add the medical fluid to the IV set at the time of use. A typical IV set uses a syringe, in which case the plunger is pressed harder or faster by hand to increase the fluid flow rate, which can result in muscle fatigue and / or insufficient increase in fluid flow rate.

[0003] For these reasons, it is desirable to provide an IV set having a syringe engagement member that is driven via a reusable mechanized actuator to minimize muscle fatigue and quickly increase the volume of fluid pushed through the IV set and / or effectively push highly viscous fluids through the IV set.

[0020] The detailed description set forth below describes various configurations of the subject technology and is not intended to represent the only configuration that can practice the subject technology. The specific implementation includes specific details for the purpose of providing a thorough understanding of the subject technology. Therefore, the dimensions about certain aspects are provided as non-limiting examples. However, it is clear to those skilled in the art that the subject technology can be implemented without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid blurring the concept of the subject technology.

[0021] It should be understood that the present disclosure includes examples of subject technology and does not limit the scope of the appended claims. The following will illustrate various aspects of the subject technology according to specific but non-limiting examples. The various embodiments described in this disclosure can be implemented in different ways and variations and according to the intended application and implementation.

[0022] Referring now in more detail to the drawings, in which like reference numerals designate identical or corresponding elements throughout the several views, Figure 12 shows a patient care system 20 having four infusion pumps 22, 24, 26, and 28, each of which is fluidly connected to an upstream fluid line 30, 32, 34, and 36, respectively. Each of the four infusion pumps 22, 24, 26, and 28 is also fluidly connected to a downstream fluid line 31, 33, 35, and 37, respectively. The fluid lines can be any type of fluid conduit through which fluid can flow, such as an IV administration set. It should be understood that any of a variety of pump mechanisms can be used, including a syringe pump.

[0023] Fluid supplies 38, 40, 42, and 44 can take a variety of forms, but in this case are shown as bottles that are inverted and suspended above the pump. Fluid supplies can also take the form of bags or other types of containers including syringes. Patient care system 20 and fluid supplies 38, 40, 42, and 44 are mounted on a roller stand, IV pole 46, a countertop, etc.

[0024] Individual infusion pumps 22, 24, 26 and 28 are used to infuse each fluid from a fluid supply source into a patient. An infusion pump is a flow control device that acts on a corresponding fluid line to move fluid from a fluid supply source through the fluid line to a patient 48. Since independent pumps are used, each pump can be individually set to infuse a specific medical fluid from a corresponding fluid supply source into a patient at a specific rate specified by a clinician for that fluid to a desired pumping or operating parameter. Such medical fluids may include medications or nutrients or other fluids. Infusion pumps 22, 24, 26 and 28 are controlled by a pump control unit 60.

[0025] Fluid supplies 38, 40, 42 and 44 are each coupled to an electronic data tag 81, 83, 85 and 87, respectively, or to an electronic transmitter.Any device or component associated with the infusion system may be equipped with an electronic data tag, reader or transmitter.

[0026] Typical infusion sets can also be gravity sets that do not require the use of an infusion pump. For example, any one of the fluid supply sources 38, 40, 42, and 44 can be directly connected to the patient 48 via a gravity IV set, wherein gravity causes the fluid to flow through the infusion set and into the patient 48 without the aid of a pump.

[0027] Typically, a medical fluid administration kit has Figure 1 More parts shown, such as Figure 2Parts shown. The IV set can be formed of any combination of infusion components and tubing. Typically, the infusion components and tubing are disposable products that are discarded after a single use. The infusion components and tubing can be formed of any suitable material (e.g., plastic, silicone, rubber), many or all of which are transparent or translucent so that the fluid flow or liquid level inside can be seen.

[0028] like Figure 2 As shown, the IV set 120 may include a drip chamber 130, a syringe 140, and a roller clamp 150 connected together by tubing 160. The IV set 120 may also include a Y-shaped component 170 having a Y-shaped connector with a needleless connector 175, and a Luer lock connector 180 located at the end of the IV set 120. For example, the Luer lock connector 180 can be used to connect to a catheter inserted into a patient. The IV set 120 may include additional infusion components and may be formed from any combination of components and tubing 160.

[0029] In use, the IV set 120 is connected to an IV fluid bag (e.g., a saline solution bag) via the drip chamber 130, while the Luer lock connector 180 is connected to a catheter placed in a patient's vein. Thus, fluid flows from the fluid bag through the drip chamber 130, through the rest of the IV set 120, and out of the Luer lock connector 180. When the plunger 142 of the syringe 140 is depressed, a volume of fluid (e.g., medication, medical fluid) contained within the syringe body 144 is squeezed out of the outlet port 146 and downstream through the IV set 120. When the syringe 140 is released (e.g., the plunger stops being pushed), the flow of fluid from the syringe 140 into the IV set 120 stops. This syringe cycle can be repeated by disconnecting the used syringe 140 and connecting to another syringe 140 with additional fluid to move fluid from one or more syringes 140 into the patient as quickly as possible.

[0030] The syringe body 144 is a typical rigid cylinder with a rigid plunger 142, which the user continuously pushes or presses with one hand until the desired amount of medical fluid in the syringe 140 is dispensed. However, the smooth cylindrical shape of the syringe body 144 and the rigid feel of the syringe 140 provide an ergonomic shape and texture for the hand to hold, and there are no additional features to facilitate the dispensing of fluid downstream from the syringe 140. Therefore, the cylindrical geometry of the syringe 140 and the rigid texture of the syringe body 144 and plunger 142 are generally uncomfortable for prolonged use and may quickly cause hand fatigue in the user. In addition, depending on the viscosity of the medical fluid to be dispensed by the syringe 140, it may take a long time to manually depress the plunger 142 and / or require additional manual strength to depress the plunger 142.

[0031] Often need to deliver intravenous fluid and / or medicine quickly. The subject technology promotes the rapid infusion of fluid / medicine to the patient by including a syringe joint on a disposable IV kit. The syringe joint can be engaged with a power driver (e.g., a reusable driver) that rotates a threaded shaft to press a plunger and deliver fluid from a syringe. The syringe joint and the driver can be configured to achieve a desired target flow rate of the fluid from the syringe.

[0032] In aspects of the present disclosure, disposable syringe couplings are integrated into the IV kit. The syringe coupling can be engaged by a power driver, which provides a rotational input to the syringe coupling, which is converted into a slidable motion of the plunger in the body of the syringe. Then, the syringe delivers fluid from the syringe to the remaining IV kits to reach the patient at a rapidly increasing flow rate. This reduces or eliminates the hand fatigue caused by the user manually pushing the fluid from the syringe (e.g., with syringe 140), and rapidly accelerates the infusion rate of the new fluid being delivered to the patient. In addition, different from the manual operation of syringe 140, the syringe coupling and the power driver provide an increased fluid distribution rate by rotating the driver interface faster rather than having to push the plunger into the syringe body faster by hand, and provide a more continuous fluid distribution, which is opposite to the distribution rate that varies based on different users, the strength of the hand, the fatigue of the hand, etc.

[0033] In aspects of the present disclosure, the syringe engagement piece can be configured to be driven by any suitable drive shaft (e.g., a hexagonal shaft similar to a power screw driver). For example, the syringe engagement piece can be driven by an intraosseous driver available from Becton Dickinson & Company. In this article, a disposable syringe engagement piece can be configured to engage with the intraosseous driver. In aspects of the present disclosure, a disposable engagement piece key can be included in the IV kit, which disposable engagement piece key is configured to work with one or more specific power drivers. In aspects of the present disclosure, any suitable syringe can be used.

[0034] like Figure 3 As shown, an IV set 200 including a syringe coupling 210 is provided according to aspects of the present disclosure. For example, the IV set 200 can include all of the components of the IV set 120, with the addition of the syringe coupling 210. The IV set 200 can include additional infusion components and can be formed from any combination of components and tubing 160.

[0035] The syringe interface 210 can be formed of any suitable material (e.g., polymer, rubber, plastic) that is configured to contact a syringe containing a medical fluid (e.g., saline solution, medication). The material of the syringe interface 210 can be flexible or non-flexible and can be any single material or combination of materials selected or designed to provide the desired amount of flexibility / non-flexibility and service life cycle.

[0036] like Figure 4 As shown, in aspects of the present disclosure, the syringe interface 210 may include a housing 212, an outlet port 214, a drive engagement coupling 216, and a drive engagement 218. The outlet port 214 may be configured to receive an outlet port (e.g., outlet port 146) of a syringe (e.g., syringe 140), and the drive engagement 218 may rotatably abut the drive engagement coupling 216. For example, the drive engagement coupling 216 may be a threaded edge of the housing 212 or a threaded profile (e.g., semicircular) of the housing 212. The syringe interface 210 may be added to an existing IV set (e.g., IV set 120) by connecting the housing 212 to a syringe port (e.g., needleless port 175 of Y-connector 170). For example, the housing 212 may be snap-fit ​​onto the needleless port 175 such that one end of the needleless port 175 extends through the outlet port 214 and into the housing 212. As another example, the outlet port 214 can be threaded, and the housing 212 can be screwed onto the threads of the needleless port 175 such that one end of the needleless port 175 extends through the outlet port 214 and into the housing 212. In yet another example, the housing 212 can be secured to the needleless port 175 by any suitable operation (e.g., gluing, welding, clamping) such that one end of the needleless port 175 extends through the outlet port 214 and into the housing 212.

[0037] In use, a syringe 140 containing a medical fluid may be inserted into the syringe interface 210 by coupling the outlet port 146 of the filled syringe 140 to the needle-free port 175 (e.g., screwing the threaded outlet port 146 into the threaded needle-free port 175). As an example, both the outlet port 146 and the end portion of the needle-free port 175 may be disposed within the outlet port 214. As another example, the end portion of the needle-free port 175 may extend into the housing 212 such that the coupling between the outlet port 146 and the needle-free port 175 is located within the housing 212. In yet another example, the outlet port 146 of the syringe 140 may extend through the outlet port 214 of the housing 212 such that the coupling between the outlet port 146 and the needle-free port 175 is located outside the housing 212.

[0038] In addition, the plunger 142 of the syringe 140 can be engaged or coupled with the drive engagement member 218. For example, the drive engagement member 218 can be internally threaded into the housing 212 to engage the plunger 142. As another example, the plunger 142 can be slidably moved into or out of the syringe body 144 to contact the drive engagement member 218. In yet another example, the drive engagement member 218 may not contact the plunger 142 (e.g., a gap is provided between the drive engagement member 218 and the plunger 142) until the syringe 140 is required to be operated.

[0039] Figure 5 A syringe engagement member 210 is shown having a loaded syringe 140 and a driver 250 coupled to a drive shaft 254 via a driver interface 252. In this context, the drive shaft 254 may be a threaded shaft configured to couple with threads of a drive engagement member 218. For example, operating the driver 250 causes the drive shaft 254 to rotate, which causes the coupled threaded drive engagement member 218 to rotate against the threaded drive engagement coupling 216, which in turn causes the drive engagement member 218 to move laterally toward the syringe body 144 to engage the plunger 142 and / or to slide the plunger into the syringe body 144. In aspects of the present disclosure, the drive shaft 254 may be configured to be held against the drive engagement member 218 by a user force on the driver 250. In aspects of the present disclosure, the drive shaft 254 may be configured to be received by the housing 212 such that the threads of the drive shaft 254 engage with the threads of the drive engagement member 218.

[0040] like Figure 6As shown, in aspects of the present disclosure, the syringe coupling 210a can include a housing 212a, an outlet port 214a, a drive engagement coupling 216a, and a drive engagement 218a. The outlet port 214a can be configured to receive an outlet port (e.g., outlet port 146) of a syringe (e.g., syringe 140), and the drive engagement coupling 218a can be rotatably engaged to the drive engagement coupling 216a. For example, the drive engagement coupling 216a can be a threaded hole or opening of the housing 212a. The syringe coupling 210a can be added to an existing IV kit (e.g., IV kit 120) by connecting the housing 212a to a syringe port (e.g., a needleless port 175 of a Y-shaped connector 170). For example, the housing 212a can be snap-fitted onto the needleless port 175 so that one end of the needleless port 175 extends through the outlet port 214 and into the housing 212a. As another example, the outlet port 214a can be threaded, and the housing 212a can be screwed onto the threads of the needleless port 175 such that one end of the needleless port 175 extends through the outlet port 214a and into the housing 212a. In yet another example, the housing 212a can be secured to the needleless port 175 by any suitable operation (e.g., gluing, welding, clamping) such that one end of the needleless port 175 extends through the outlet port 214a and into the housing 212a.

[0041] In use, a syringe 140 containing a medical fluid may be inserted into the syringe interface 210a by coupling the outlet port 146 of the filled syringe 140 to the needleless port 175 (e.g., screwing the threaded outlet port 146 into the threaded needleless port 175). As an example, both the outlet port 146 and the end portion of the needleless port 175 may be disposed within the outlet port 214a. As another example, the end portion of the needleless port 175 may extend into the housing 212a such that the coupling between the outlet port 146 and the needleless port 175 is located within the housing 212a. In yet another example, the outlet port 146 of the syringe 140 may extend through the outlet port 214a of the housing 212 such that the coupling between the outlet port 146 and the needleless port 175 is located outside the housing 212a.

[0042] In addition, the plunger 142 of the syringe 140 can be engaged or coupled with the drive engagement member 218a. For example, the drive engagement member 218a can pass through the drive engagement coupling portion 216a to engage the plunger 142. As another example, the plunger 142 can slide into or out of the syringe body 144 to contact the drive engagement member 218a. In yet another example, the drive engagement member 218a may not contact the plunger 142 (e.g., a gap is provided between the drive engagement member 218a and the plunger 142) until the syringe 140 needs to be operated.

[0043] Figure 7 A syringe engagement member 210a is shown having a loaded syringe 140 and a driver 250 coupled to a drive engagement member 218a via a driver interface 252. Herein, the drive engagement member 218a may have an end portion that is sized and shaped to be received by the driver interface 252. For example, operating the driver 250 causes the threaded drive engagement member 218 to rotate within the threaded drive engagement coupling 216a, which in turn causes the drive engagement member 218a to move laterally toward the syringe body 144 to engage the plunger 142 and / or slideably push the plunger into the syringe body 144. In aspects of the present disclosure, the drive engagement member 218 may be assembled with the syringe engagement member 210 and configured to quickly connect (e.g., snap fit to) the driver interface 252 of the driver 250. In aspects of the present disclosure, the drive engagement member 218 may be assembled with the driver 250 and configured to quickly connect (e.g., threaded to) the threaded drive engagement coupling 216a.

[0044] In aspects of the present disclosure, syringe interface 210, 210a can be discarded with IV set 200 when use and / or life of IV set 200 or any component of IV set 200 is complete. For example, syringe interface 210, 210a can be manufactured and / or used as a low-cost disposable component.

[0045] The drive engagement member 218, 218a can be sized and shaped to include any suitable end (e.g., a flat edge end, a shaped end) that is received by a corresponding end surface of the plunger 142. For example, the drive engagement member 218 or the drive engagement member 218a can be configured to engage an end of the plunger 142, such as Figure 4 The syringe coupling member 210 and Figure 6 The other end of the drive coupling 218 can be engaged by the drive shaft 254 of the driver 250 (see Figure 5 ), and the other end of the drive engagement member 218a can be engaged by the drive interface 252 of the driver 250 (see Figure 7 ).

[0046] In aspects of the present disclosure, the drive engagement member 218, 218a can be coupled to the housing 212, 212a as an integral part of the syringe engagement member 210, 210a during manufacture / assembly of the IV set 200. In aspects of the present disclosure, the drive engagement member 218, 218a can be coupled to the housing 212, 212a before the IV set 200 is put into use. In aspects of the present disclosure, the drive engagement member 218, 218a can be coupled to the housing 212, 212a as needed only after the IV set 200 is put into use. For example, one end of the drive coupling 218, 218a can be connected to the drive shaft 254 and the drive interface 252 of the driver 250, and the other end of the drive coupling 218, 218a can be engaged with the plunger 142 of the syringe 140 only when a high fluid dispensing rate and / or a high viscosity fluid is dispensed from the syringe 140, while the drive coupling 218, 218a can be disengaged from the drive shaft 254 and the drive interface 252 when it is not desired to dispense fluid from the syringe 140.

[0047] In aspects of the present disclosure, the drive shaft 254 can be a part of the syringe engagement member 210 or a part of the driver 250, wherein the driver 250 and the drive shaft 254 directly interface. In aspects of the present disclosure, the drive engagement member 218a can be a part of the syringe engagement member 210a or a part of the driver 250, such that the driver 250 and the drive engagement member 218a directly interface. In aspects of the present disclosure, any of the drive shaft 254, the drive engagement member 218, and the drive engagement member 218a can be a separate disposable component that can be provided with the IV set 200.

[0048] like Figure 8 As shown, in aspects of the present disclosure, the driver 250 can be a rechargeable device configured to be charged by a charging component 256. In aspects of the present disclosure, the driver 250 can have a power cord and be powered by plugging into a power source (e.g., a wall outlet). In aspects of the present disclosure, the driver 250 can be configured to clamp to any appropriate structure (e.g., an IV pole, a hospital bed). In aspects of the present disclosure, the driver 250 can be configured to operate at a fixed speed and / or a variable speed.

[0049] like Fig. 9 As shown, the syringe coupling 210, 210a can be part of an IV set 300. The IV set 300 can include a fluid bag 190, a drip chamber 130, a roller clamp 150, a Y-shaped connector 170 with a needleless port 175, a syringe coupling 210, 210a, and a Luer connector 180, all of which are connected together by IV tubing 160.

[0050] In aspects of the present disclosure, the syringe engagement member 210, 210a, when not activated (e.g., not powered by the driver 250), can be a passive inline device, wherein fluid from the fluid bag 190 is received downstream via the drip chamber 130 and at a flow rate controlled by any of gravity, the volume of fluid in the fluid bag 190, and / or the roller clamp 150. In use, when the syringe 140 is coupled to the syringe engagement member 210, 210a and the drive engagement member 218, 218a is rotated via the driver 250, the volume of fluid contained within the syringe body 144 can be quickly forced out of the outlet port 214, 214a over multiple rotations of the drive engagement member 218, 218a.

[0051] This rotation of the drive coupling 218, 218a causes the fluid to flow quickly from the syringe 140 to the remaining downstream portion of the IV set 200 (e.g., faster than manually depressing the plunger would allow). Thus, continued rotation of the drive shaft 218 can cause all of the fluid to be quickly dispensed out of the syringe 140 and pushed into the desired receiving portion (e.g., the patient's arm).

[0052] In aspects of the present disclosure, the syringe connector 210, 210a can be a disposable component of the IV set 300. For example, the syringe connector 210, 210a can be an integral component of the IV set 300, wherein the syringe connector 210, 210a can be coupled to the needleless port 175. Thus, the syringe connector 210, 210a will only be used within the life of the IV set 300 (e.g., 24 hours, 72 hours, 7 days), after which the syringe connector 210, 210a will be discarded along with the associated IV set 300. In aspects of the present disclosure, the syringe connector 210, 210a can be coupled to any component within the IV set 300, such as directly to the fluid bag 190 through an injection port.

[0053] In use, the IV set 300 having the disposable syringe coupling 210, 210a is coupled to a fluid container (e.g., fluid bag 190) containing a medical fluid (e.g., saline solution). In the unactivated state, the syringe coupling 210, 210a has a static drive coupling 218, 218a, thereby allowing fluid to flow through the IV set 300 at a rate set by a flow controller (e.g., roller clamp 150) without introducing medical fluid within the syringe 140. When it is necessary to quickly add medical fluid within the syringe 140, the drive coupling 218 can be rotated by a drive shaft 254 coupled to the driver 250, or the drive coupling 218a can be rotated directly by the driver 250, thereby driving the medical fluid from the syringe 140 into the IV set 300 faster than manually operating the syringe 140. If more medical fluid is needed, the driver 250 can be quickly reversed to move the drive engagement 218, 218a away from the empty syringe 140, the empty syringe is removed from the syringe engagement 210, 210a, the filled syringe 140 is inserted into the syringe engagement 210, 210a, and the driver 250 is reversed again to drive the drive engagement 218, 218a against the plunger 142 of the newly inserted syringe 140 to quickly dispense the contents of the new syringe 140 into the IV set 300. In aspects of the present disclosure, the driver 250 can be configured to automatically reverse when the plunger 142 is fully depressed within the syringe 140 (e.g., when all of the fluid within the syringe 140 has been dispensed), thereby providing for rapid removal of the dispensed syringe 140 once the fluid has been dispensed, thereby allowing for rapid insertion of a new syringe 140 filled with fluid.

[0054] like Fig.10 As shown, an IV set 400 having syringe couplings 210, 210a can be coupled to a fluid source 38, to an infusion pump system 260 having two infusion pumps 262 and a controller 264, and to a catheter 270 inserted into a patient 280. Herein, if additional medical fluid needs to be quickly added to the fluid from the infusion pump system 260, the syringe couplings 210, 210a can be activated (e.g., driven by a driver 250) to force the medical fluid in the syringe 140 to be quickly dispensed into the IV set 400. In aspects of the present disclosure, the IV set 400 can be quickly separated from the infusion pump system 260 before the syringe couplings 210, 210a are used, and / or the infusion pump system 260 can be set to neutral to allow fluid from the fluid source 38 to flow unimpeded before the syringe couplings 210, 210a are used, thereby allowing a high fluid flow rate through the IV set 400 to carry the medical fluid dispensed from the syringe 140.

[0055] In aspects of the present disclosure, the syringe engagement member 210, 210a and / or the driver 250 may include any suitable fastener to couple the syringe engagement member 210, 210a and / or the driver 250 to an IV pole 46, a bed (e.g., a hospital bed), a stretcher (e.g., a rolling ambulance stretcher), an operating table, etc. For example, the fastener may be a bracket, a hanger, a hook, Adhesive and / or any other suitable fastener. In aspects of the present disclosure, the syringe interface 210, 210a can be configured to simply hang inline with an IV set (e.g., IV set 400) via a syringe port (e.g., needleless port 175). In this context, the syringe interface 210, 210a can be positioned on the IV set to maximize accessibility and / or keep the syringe interface 210, 210a out of a particular working area (e.g., directly above the patient).

[0056] In aspects of the present disclosure, medication may be rapidly administered to a patient via the pump syringe engagement 210, 210a which forces medication through the IV line at the rate at which the plunger 142 is depressed based on the rotation rate of the drive engagement 218, 218a.
