Technical Field

[0001] This utility model relates to the medical field, specifically a quick-connect connector for multiple bags of saline solution. Background Technology

[0002] Intravenous infusion refers to the administration of large doses of injectable solutions into the body via intravenous drip. These solutions are typically packaged in glass or plastic infusion bottles or bags, providing a continuous and stable delivery of medication. A single child usually requires multiple bottles or bags of medication / saline solution. In hospitals, saline solution is usually prepared and distributed in a standardized manner. When changing infusion bottles / bags, medical staff must promptly insert the needle from the bottom of the empty bottle into the connector on the bottom of the new infusion bottle.

[0003] When connecting saline or medication to the children in the ward, the medical staff are dealing with a large number of children, making the connection process not only cumbersome and inconvenient, increasing the workload of nurses, but also increasing the probability of errors.

[0004] In addition, frequent changes to saline bags may cause patients to have questions about the number of saline bags, increasing the difficulty of doctor-patient communication.

[0005] Therefore, a special device is needed to facilitate the connection of saline / medication solution in order to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a quick-connect connector for multiple bags of saline solution. Through the cooperation of adapter components, suspension structure and connectors, it can meet the needs of fixing, connecting and flushing multiple infusion bags. The operation is convenient and efficient, effectively improving the work efficiency of medical staff.

[0007] A quick-connect connector for multi-bag saline solution includes a multi-port connector, a dispensing connector, and multiple infusion bags for use. One end of the dispensing connector is connected to multiple infusion bags simultaneously via the multi-port connector, and the multi-port connector and the infusion bags are detachably connected. The other end of the dispensing connector is connected to an existing infusion tubing. The multi-port connector is equipped with a conversion component for changing the flow state between the multiple infusion bags and the dispensing connector. The conversion component allows one infusion bag to connect to the dispensing connector while simultaneously blocking the flow between other infusion bags and the dispensing connector. The multi-port connector has multiple transmission lines. The conversion component includes an adjusting rod, a pressure element, a control element, and a linkage element. The pressure element has a fan-shaped structure and is arranged around the adjusting rod. The side of the pressure element away from the adjusting rod is an arc-shaped surface, and the side of the adjusting rod without the pressure element is a gap. The control element is located at the multi-port connector and drives the adjusting rod to rotate via the linkage element. In use, multiple transmission lines are restricted by the pressure element, and one transmission line is not compressed.

[0008] Compared with existing technologies, the quick-connect connector for multi-bag saline solution using the above technical solution has the following advantages:

[0009] The quick-connect connector for multi-bag saline solution of this invention connects the infusion bag and the infusion tubing through a multi-port connector and a liquid outlet connector. With the switching operation of the adapter component, it can achieve the purpose of individually connecting one bag of medicine to the infusion tubing for infusion.

[0010] By coordinating the control components, linkage components, and adjusting rods, the function of driving the fan-shaped pressing component to rotate is achieved. By utilizing the pressing force of the outer circumferential surface of the pressing component and the gap provided by the empty part, while satisfying the passage status of one transmission pipeline, the passage status of other transmission pipelines can be simultaneously compressed and restricted.

[0011] Preferably, the linkage includes a toothed portion and a gear ring. The toothed portion surrounds the surface of the adjusting rod, and the control component is a knob movably located at the multi-port connector. The gear ring is located on the outer periphery of the knob, and the toothed portion meshes with the gear ring. A damping component is provided between the knob and the multi-port connector. Utilizing the meshing relationship of the toothed structure, the adjusting rod and the pressure component are adaptively rotated simultaneously with the rotation. Furthermore, the teeth on both the toothed portion and the gear ring are evenly spaced, allowing for precise control of the transmission pipeline by marking the gear ring. In addition, the damping component's deceleration and buffering effect enables the positioning of the adjusting rod after adjustment and avoids excessive adjustment.

[0012] Preferably, the multi-port connector has multiple docking seats on the side away from the outlet connector that communicate with the transmission tubing. A sterile tubing is located on the underside of the infusion bag. The docking seats can be tightly fitted onto the sterile tubing, and a needle hub for connecting the infusion bag is located inside the docking seat. By utilizing the tight wrapping and the insertion of the needle hub, a stable connection and communication between the sterile tubing and the docking seats are achieved.

[0013] Preferably, the device also includes a suspension seat and hooks. The suspension seat has multiple limiting hooks, and the bag body has hanging holes adapted to the limiting hooks. It also includes a flushing assembly for flushing the infusion tubing. The combined use of multiple limiting hooks and hanging holes allows for the suspension of multiple infusion bags. The shape of the suspension seat and the position of the limiting hooks can be adapted to the specific needs of the hospital.

[0014] Preferably, the flushing assembly includes a flushing tubing, a flushing connector, and a protective cap. The flushing tubing is located between the suspension seat and the outlet connector, the flushing connector is located at the end of the flushing tubing near the suspension seat, and the protective cap is connected to the flushing connector via an anti-loss strap made of elastic material. This external flushing connector and outlet connector's mating structure meets the flushing needs of medical personnel during flushing, and the anti-loss strap eliminates the need to consider the placement of the protective cap during flushing, facilitating subsequent resealing of the protective cap.

[0015] Preferably, the infusion bag is equipped with a drug delivery connector made of sterile material.

[0016] Preferably, the medication delivery connector is threaded with a sealing cap. For patients requiring medication, drugs can be added promptly during the infusion process, and the threaded structure ensures the connection and sealing effect of the sealing cap. Attached Figure Description

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] like Figures 1 to 7 The multi-bag saline quick-connect fitting shown includes a multi-port connector 1, an outlet connector 2, a hanging seat 7, a hook 70, and multiple infusion bags 3 for use with it.

[0027] One end of the outlet connector 2 is connected to multiple infusion bags 3 simultaneously via a multi-port connector 1, and the multi-port connector 1 is detachably connected to the infusion bags 3. The other end of the outlet connector 2 is connected to the existing infusion pipeline 0.

[0028] In this case, the outlet connector 2 adopts the existing heparin cap connector, and the starting end of the infusion line 0 is a needle structure, which can be inserted into the outlet connector 2 to achieve the purpose of internal passage.

[0029] The multi-port connector 1 is provided with a conversion component 4 for changing the passage status of multiple infusion bags 3 and outlet connector 2. The conversion component 4 can make one infusion bag 3 connect to the outlet connector 2, while blocking the passage between other infusion bags 3 and outlet connector 2.

[0030] The multi-port connector 1 is equipped with multiple transmission lines 10, the same number as the infusion bags 3.

[0031] The adapter assembly 4 in this case includes an adjusting rod 40, a pressing member 41, a control member, and a linkage member.

[0032] The pressing member 41 has a fan-shaped structure and is arranged around the adjusting rod 40. The side of the pressing member 41 away from the adjusting rod 40 is an arc-shaped surface 42, and the side of the adjusting rod 40 without the pressing member 41 is a blank part 44. The control member is located at the multi-port connector 1, and the control member drives the adjusting rod 40 to rotate through the linkage. In the use state, multiple transmission pipelines 10 are restricted by the pressing member 41, and one of the transmission pipelines 10 is not compressed.

[0033] In order to achieve real-time control of the adjusting rod 40 and to avoid the problem of autonomous changes in the internal passage, the linkage of this invention includes a toothed part 50 and a toothed ring 51. The toothed part 50 is arranged around the surface of the adjusting rod 40. The control component is a knob 43 that is movably arranged at the multi-port connector 1, and the toothed ring 51 is arranged on the outer periphery of the knob 43. The toothed part 50 and the toothed ring 51 are engaged and connected. A damping component 52 (made of elastic silicone or thin layer of rubber) is provided between the knob 43 and the multi-port connector 1.

[0034] To enhance stability during use and meet the requirements for fluid continuity, the connection structure between the multi-port connector 1 and the infusion bag 3 features multiple docking seats 6 on the side of the multi-port connector 1 away from the outlet connector 2, which are connected to the transmission tubing 10. These docking seats 6 can be made of medical-grade silicone. The underside of the infusion bag 3 has a sterile tubing 31 (such as the existing heparin cap structure) that communicates with the inside of the infusion bag 3. The docking seats 6 can be tightly fitted onto the sterile tubing 31, and the interior of the docking seats 6 contains a needle hub 60 for connecting to the infusion bag 3.

[0035] To facilitate the simultaneous mounting of multiple infusion bags 3, the suspension seat 7 is provided with multiple limiting hooks 71, and the bag body is provided with hanging holes 30 that are adapted to the limiting hooks 71.

[0036] In addition, to ensure the cleanliness of the infusion tubing 0 and avoid drug reactions, a flushing assembly 8 for flushing the infusion tubing 0 is also included.

[0037] The flushing assembly 8 in this case includes a flushing pipe 80, a flushing connector 81, and a protective cover 82. The flushing pipe 80 is located between the suspension seat 7 and the outlet connector 2. The flushing connector 81 is located at one end of the flushing pipe 80 near the suspension seat 7, and the protective cover 82 is connected to the flushing connector 81 by an anti-loss strap 83 made of elastic material.

[0038] In addition, for applications requiring temporary medication replenishment, a special infusion bag structure 3 can be used, wherein the infusion bag 3 has a medication dispensing connector 9 made of sterile material, and a sealing cap 90 is threaded onto the medication dispensing connector 9. Both the flushing connector 81 and the medication dispensing connector 9 adopt a sterile heparin cap structure.

[0039] During use, the hanging seat 7 is first fixed to the infusion pole of the hospital bed using the hook 70, and the upper end of each infusion bag 3 is fixed to the lower part of the hanging seat 7 using the cooperation of the limiting hook 71 and the hanging hole 30. Next, the docking seat 6 on the multi-port connector 1 is fitted onto the sterile tubing 31 below the infusion bag 3. At this time, the needle seat 60 is inserted into the sterile tubing 31 with the heparin cap structure, thus connecting the multi-port connector 1 and the infusion bag 3, forming a connection as shown in the image. Figure 5 The state shown.

[0040] Next, temporarily close the access of the existing infusion line 0, and use the needle structure at the beginning of the existing infusion line 0 to insert the needle into the outlet connector 2 of the heparin cap structure to connect the multi-port connector 1 and the beginning of the infusion line 0. Then open the access of the infusion line 0 to expel any air that may be present in the line, and then perform the puncture and infusion.

[0041] If one bag of saline solution is about to run out, the knob 43 at the multi-port connector 1 can be rotated. Due to the meshing relationship between the protruding tooth 50 and the toothed ring 51, rotating the knob 43 will cause the adjusting rod 40 and the pressure member 41 to rotate. Furthermore, due to the arrangement of the arc-shaped surface 42 and the empty part 44 of the pressure member 41, such as... Figure 6 As shown, when the compression member 41 rotates, one of the transmission lines 10 is located in the empty part 44 (not compressed by the compression member 41), while the other transmission line 10 is compressed by the compression member 41 (the corresponding transmission line 10 is closed). That is, the next infusion bag 3 to be connected is separately connected to the infusion line 0, thus achieving the purpose of continuing infusion in this case. If flushing is required midway, the anti-slip cover is pulled open to allow the syringe to be inserted into the flushing connector 81 to flush the infusion line 0.

[0042] The above description is a preferred embodiment of the present utility model. For those skilled in the art, several modifications and improvements can be made without departing from the principle of the present utility model, and these should also be considered within the protection scope of the present utility model.
