Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and more specifically relates to an anti-tangle infusion set. Background Technology

[0002] Infusion sets are a common medical consumable that delivers medication via an infusion tube. Once manufactured, the length of an infusion set is fixed (usually around 1.5 meters). When the hanging height changes, the infusion tube may become too long, taking up space and easily getting tangled in other objects. If patients and medical staff are not careful, they may pull on the infusion tube, affecting the infusion process.

[0003] In the existing patent with publication number CN222566440U, entitled "An Infusion Set with a Retractable Structure", two upper and lower spiral limiting ring tubes are used. A limiting component that can adjust the distance between the two limiting ring tubes is set between the two limiting ring tubes. When using it, the infusion tube needs to be passed through the upper and lower limiting ring tubes to control the length of the infusion tube, thereby making it less likely for the infusion tube to get tangled and get caught on other objects.

[0004] Because its operation requires the infusion tubing to pass through two limiting rings, there are inconveniences in the process of connecting the infusion set. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides an anti-tangle infusion set, which eliminates the need to pass the infusion tube through the hollow ring tube, making the operation more convenient.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an anti-tangle infusion set, comprising a first clamping block and a second clamping block, an infusion tube being clamped onto the first clamping block and the second clamping block, a pull rope being provided between the first clamping block and the second clamping block, the pull rope being fixedly connected to the second clamping block, a winding mechanism being provided between the first clamping block and the pull rope, and a slot being provided on the first clamping block and the second clamping block.

[0007] The winding mechanism includes a winding wheel with a winding shaft on it. The winding wheel is rotatably connected to the first clamping block via the winding shaft. A coil spring is provided on the winding shaft, with its center end connected to the winding shaft and its outer end connected to the first clamping block. A ratchet mechanism is provided between the winding shaft and the first clamping block.

[0008] Furthermore, the ratchet mechanism includes a telescopic rod that is telescopically slidably connected to the first clamping block, a pawl disc that meshes with each other between the telescopic rod and the take-up shaft, and a meshing spring sleeved on the telescopic rod. The meshing spring is connected to the pawl disc on the telescopic rod, and the end of the telescopic rod extends out of the first clamping block, and a handle block is provided on the extended end.

[0009] Furthermore, the pull rope is provided with several limiting blocks, the limiting blocks are provided with connecting rods, the connecting rods are provided with ring hooks, the infusion tube is located inside the ring hooks, and the inner diameter of the ring hooks is larger than the outer diameter of the infusion tube.

[0010] Furthermore, the limiting block includes a first pressing block and a second pressing block, which are pressed together on both sides of the pull rope. The connecting rod is located on the first pressing block. A guide rod passing through the first pressing block is provided on the second pressing block, and a compression spring is provided on the part of the guide rod that passes through it. A fixing plate is provided at the end of the guide rod. The two ends of the compression spring are respectively connected to the fixing plate and the first pressing block. The compression spring generates elastic force to drive the second pressing block to press the pull rope tightly onto the first pressing block.

[0011] Furthermore, the ring hook is provided with an opening, and the opening is smaller than the outer diameter of the infusion tube.

[0012] Furthermore, a friction layer is provided inside the card slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Before infusion, the first clamp and the second clamp are stretched and connected to the infusion tube. The pull rope is retracted to bring the second clamp closer to the first clamp, which moves the excess infusion tube upward and bends it, and places the bent infusion tube at the top, thereby avoiding the risk of infusion tube entanglement. There is no need to pass the infusion tube through the hollow ring tube. The infusion tube can be simply inserted into the slot, making the operation more convenient. Attached Figure Description

[0019] Reference Figure 1 and Figure 2 The present invention will be further described below.

[0020] An anti-tangle infusion set includes a first clamping block 1 and a second clamping block 2. An infusion tube 3 is clamped onto the first clamping block 1 and the second clamping block 2. A pull rope 4 is provided between the first clamping block 1 and the second clamping block 2. The pull rope 4 is fixedly connected to the second clamping block 2. A winding mechanism is provided between the first clamping block 1 and the pull rope 4. A slot 5 is provided on the first clamping block 1 and the second clamping block 2.

[0021] The winding mechanism includes a winding wheel 7, on which a winding shaft 8 is provided. The winding wheel 7 is rotatably connected to the first clamping block 1 via the winding shaft 8. A coil spring 6 is provided on the winding shaft 8. The center end of the coil spring 6 is connected to the winding shaft 8, and the outer end is connected to the first clamping block 1. A ratchet mechanism is provided between the winding shaft 8 and the first clamping block 1.

[0022] like Figure 1As shown, before infusion, the first clamp 1 and the second clamp 2 are used to stretch the pull rope 4 and connect it to the infusion tube 3. When the pull rope 4 is stretched, the winding shaft 8 is rotated. The winding shaft 8 drives the coil spring 6 to roll inward, generating rotational elasticity. The winding shaft 8 is fixed by the ratchet mechanism, thus maintaining the stretched state of the pull rope 4. When it is necessary to reduce the length of the infusion tube 3, the ratchet mechanism is released, allowing the winding shaft 8 to rotate freely. At this time, the rotational elasticity of the coil spring 6 is released, driving the winding shaft 8 to rotate, so that the pull rope 4 can be rewound onto the winding wheel 7, so that the second clamp 2 is close to the first clamp 1, and the excess infusion tube 3 is pulled upward and bent, and the bent infusion tube 3 is placed at the top, thus avoiding the risk of the infusion tube 3 getting tangled.

[0023] There is no need to pass the infusion tube 3 through the hollow ring tube; simply insert the infusion tube 3 into the slot 5 for easier operation.

[0024] Specifically, both ends of the slot 5 are rounded chamfers, which increases the bending angle of the infusion tube 3 at the end of the slot 5 when it is bent, thus preventing the infusion tube 3 from forming folds and blocking the flow of internal medicine.

[0025] Specifically, the pull rope 4 can be wrapped around the second clamping block 2 and knotted to connect to the second clamping block 2, making it convenient to disassemble the pull rope 4.

[0026] like Figure 1 As shown, in this preferred embodiment, the ratchet mechanism includes a telescopic rod 10 that is telescopically slidably connected to the first clamping block 1, a ratchet disc 11 that is mutually engaged with the ratchet teeth between the telescopic rod 10 and the take-up shaft 8, and a meshing spring 12 sleeved on the telescopic rod 10. The meshing spring 12 is connected to the ratchet disc 11 on the telescopic rod 10. The end of the telescopic rod 10 extends out of the first clamping block 1, and a handle block 13 is provided on the extended end.

[0027] Specifically, the engagement spring 12 generates elastic force to drive the pawl disc 11 on the telescopic rod 10 to engage with the pawl disc 11 on the take-up shaft 8. Since the telescopic rod 10 and the first clamping block 1 are only slidably connected, the take-up shaft 8 can be prevented from rotating. When the telescopic rod 10 is pulled, the two pawl discs 11 separate, allowing the take-up shaft 8 to rotate, thereby driving it to rotate through the coil spring 6.

[0028] Specifically, the telescopic rod 10 and the first clamping block 1 can slide together through the cooperation of splines and spline grooves.

[0029] like Figure 1 and Figure 2 As shown in this embodiment, preferably, the pull rope 4 is provided with a plurality of limiting blocks 14, the limiting blocks 14 are provided with connecting rods 15, the connecting rods 15 are provided with ring hooks 16, the infusion tube 3 is located inside the ring hooks 16, and the inner diameter of the ring hooks 16 is larger than the outer diameter of the infusion tube 3.

[0030] Specifically, several limiting blocks 14 are distributed at different heights on the pull rope 4. When the pull rope 4 is wound and shortened, the limiting block 14 closest to the first clamping block 1 will contact the first clamping block 1 first, thereby temporarily blocking the pull rope 4 from continuing to wind, so as to prevent the infusion tube 3 from being excessively shortened. If the infusion tube 3 needs to be shortened further, the limiting block 14 is removed and the infusion tube 3 is taken out from the ring hook 16 until the next limiting block 14 or the second clamping block 2 contacts the first clamping block 1.

[0031] Specifically, the ring hook 16 can reduce the shaking of the infusion tube 3 when it is bent and shortened.

[0032] like Figure 2 As shown in the preferred embodiment, the limiting block 14 includes a first pressing block 17 and a second pressing block 18. The first pressing block 17 and the second pressing block 18 are pressed together on both sides of the pull rope 4. The connecting rod 15 is located on the first pressing block 17. A guide rod 19 is provided on the second pressing block 18, passing through the first pressing block 17. A compression spring 20 is provided on the part of the guide rod 19 that passes through. A fixing plate 21 is provided at the end of the guide rod 19. The two ends of the compression spring 20 are respectively connected to the fixing plate 21 and the first pressing block 17. The compression spring 20 generates elastic force to drive the second pressing block 18 to press the pull rope 4 tightly onto the first pressing block 17.

[0033] Specifically, the pull rope 4 is clamped by the first pressure block 17 and the second pressure block 18, so that the limit block 14 can be kept on the pull rope 4. When the limit block 14 is removed, the limit block 14 is pulled away from the pull rope 4 until the pull rope 4 is dislodged from between the first pressure block 17 and the second pressure block 18.

[0034] like Figure 2 As shown in this embodiment, preferably, the ring hook 16 is provided with an opening, and the opening is smaller than the outer diameter of the infusion tube 3, so as to prevent the infusion tube 3 from arbitrarily coming out of the ring hook 16.

[0035] In this preferred embodiment, a friction layer is provided in the slot 5 to increase the friction between the clamping block and the infusion tube 3, and to prevent relative sliding between the clamping block and the infusion tube 3 when the pull rope 4 is wound and shortened.

[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
