Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to an infusion tubing restraint assembly with anti-removal function. Background Technology

[0002] In the process of treating patients in hospitals, intravenous injection, commonly known as infusion, is used. However, during the infusion process, external factors or impatience from patients with mental illness can lead to tube dislodgement or removal, affecting the effectiveness of the infusion. Therefore, anti-removal devices are needed to assist in the infusion process.

[0003] When using existing infusion tubing restraint devices, there is still a risk that patients with mental disorders or agitation may touch the needle during the infusion process, thereby pulling out the infusion tubing, which could lead to infusion failure. Therefore, there is a need for an infusion tubing restraint device with anti-pulling function. Utility Model Content

[0004] The purpose of this invention is to provide an infusion tubing restraint assembly with anti-pull-out function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An infusion tubing restraint assembly with anti-pull-out function includes a housing. Two rotating shafts are symmetrically rotatably connected within the housing. Clamping rings are fixedly sleeved on the outer walls of both rotating shafts. A sponge layer is fixedly disposed on the inner wall of each clamping ring. A winding wheel is fixedly sleeved on the outside of each rotating shaft. A connecting rope is wound around the winding wheel. A lifting plate is fixedly connected to one end of the connecting rope, and the other end of the connecting rope is fixedly connected to the outer wall of the winding wheel. A top support column is fixedly connected to the bottom of the lifting plate. A sleeve is slidably sleeved on the outside of the top support column, and a connecting pipe is fixedly connected to the bottom end of the outer wall of the sleeve.

[0007] Furthermore, a limiting ring is fixedly connected to the side wall of the housing, a hydraulic cylinder is fixedly sleeved in the limiting ring, the bottom end of the hydraulic cylinder is fixedly connected to the connecting pipe, a piston plate is slidably sleeved in the hydraulic cylinder, a threaded column is rotatably connected at the center of the piston plate, a fixed plate that is screwed into the threaded column is fixedly connected to the top of the hydraulic cylinder, and a rotating seat is fixedly connected to the top of the threaded column.

[0008] Furthermore, a torsion spring is sleeved on the outside of the rotating shaft, and the end of the torsion spring is fixedly connected to the clamping ring.

[0009] Furthermore, the housing contains two symmetrically fixed limiting posts that are slidably connected to the lifting plate.

[0010] Furthermore, a positioning sleeve is fixedly connected to the bottom of the housing, a sliding seat is slidably connected in the positioning sleeve, a disinfection cotton pad is fixedly provided at the bottom of the sliding seat, and multiple compression springs are fixedly connected at equal intervals at the top of the sliding seat.

[0011] Furthermore, a positioning post is fixedly connected to the top of the housing, and multiple tube-winding blocks are fixedly connected at equal intervals on the opposite sidewalls of the positioning post.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. During infusion, two clamps are used to connect to the patient's wrist or arm. A rotating seat drives a threaded column, which in turn moves a piston plate downwards within a hydraulic cylinder. This forces hydraulic oil from the cylinder through the connecting pipe into the sleeve. Under hydraulic pressure, the top support column rises, which in turn raises a lifting plate. The lifting plate simultaneously raises one end of the connecting rope on each side of the bottom. Because the connecting rope is wound around a winding wheel, when one end of the connecting rope is pulled, the winding wheel drives the rotating shaft and... The clamping rings rotate, clamping the patient's infusion site tightly. This allows the assembly to restrain the infusion tubing and needle. A sponge layer on the inner wall of the clamping rings provides comfort during restraint. After the infusion ends, the rotating seat rotates in the opposite direction, creating negative pressure in the hydraulic cylinder and drawing out the hydraulic oil from the sleeve. This causes the top support column to lower the lifting plate, which in turn drives the torsion spring to rotate the rotating shaft and clamping rings outward. As a result, the clamping rings loosen their grip on the patient's arm or other limbs, making it convenient to use.

[0014] 2. The positioning sleeve is equipped with a sliding seat connected to a compression spring. When the restraint assembly is clamped on the patient's arm, the compression spring can compress the sliding seat and the sterile cotton pad to press the infusion needle position, thereby preventing mentally unstable patients or those suffering from agitation from accidentally knocking the infusion head off during infusion, which would cause infusion failure.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 In this embodiment of the present invention, an infusion tubing restraint assembly with anti-pull-out function includes a housing 101. Two rotating shafts 203 are symmetrically rotatably connected in the housing 101. Clamping rings 201 are fixedly sleeved on the outer walls of the two rotating shafts 203. A sponge layer 202 is fixedly provided on the inner wall of the clamping rings 201. A winding wheel 205 is fixedly sleeved on the outside of the rotating shafts 203. A connecting rope 206 is wound around the winding wheel 205. One end of the connecting rope 206 is fixedly connected to a lifting plate 103. The other end of the connecting rope 206 is fixedly connected to the outer wall of the winding wheel 205. A top support column 208 is fixedly connected to the bottom of the lifting plate 103. A sleeve 207 is slidably sleeved on the outside of the top support column 208. A connecting pipe 209 is fixedly connected to the bottom end of the outer wall of the sleeve 207. Two limiting columns 102 that are slidably connected to the lifting plate 103 are symmetrically fixedly connected in the housing 101.

[0023] Specifically, during infusion, two clamps 201 are used to connect to the patient's wrist or arm. Then, the rotating seat 214 drives the threaded column 213 to rotate, causing the threaded column 213 to move the piston plate 212 downwards within the hydraulic cylinder 210. This forces the hydraulic oil in the hydraulic cylinder 210 through the connecting pipe 209 into the sleeve 207. Under hydraulic pressure, the top support column 208 rises, which in turn raises the lifting plate 103. 3 can simultaneously raise one end of the connecting rope 206 on both sides of the bottom. Since the connecting rope 206 and the winding wheel 205 are connected, when one end of the connecting rope 206 is pulled, the winding wheel 205 can drive the rotating shaft 203 and the clamping ring 201 to rotate. This allows the two clamping rings 201 to clamp the patient's infusion position, so that the component can restrain the infusion tube and infusion needle. By providing a sponge layer 202 on the inner wall of the clamping ring 201, a certain degree of comfort can be maintained when restraining.

[0024] Example 1

[0025] like Figure 4 As shown, in this embodiment, a limiting ring 211 is fixedly connected to the side wall of the housing 101. A hydraulic cylinder 210 is fixedly sleeved in the limiting ring 211. The bottom end of the hydraulic cylinder 210 is fixedly connected to the connecting pipe 209. A piston plate 212 is slidably sleeved in the hydraulic cylinder 210. A threaded column 213 is rotatably connected at the center of the piston plate 212. A fixing plate 215 that is screwed into the threaded column 213 is fixedly connected to the top end of the hydraulic cylinder 210. A rotating seat 214 is fixedly connected to the top end of the threaded column 213. A torsion spring 204 is sleeved on the outside of the rotating shaft 203. The end of the torsion spring 204 is fixedly connected to the clamping ring 201.

[0026] In this embodiment, when the infusion is finished, it can reverse the rotation of the rotating seat 214, thus generating negative pressure in the hydraulic cylinder 210 and drawing out the hydraulic oil in the sleeve 207. Therefore, the top support column 208 will drive the lifting plate 103 to descend, so the torsion spring 204 can drive the rotating shaft 203 and the clamping ring 201 to rotate outward. Therefore, the clamping ring 201 can loosen the clamp on the patient's arm and other limbs, making it more convenient to use.

[0027] Example 2

[0028] like Figure 5 As shown, in this embodiment, a positioning sleeve 104 is fixedly connected to the bottom of the housing 101, a sliding seat 105 is slidably sleeved in the positioning sleeve 104, a disinfection cotton pad 106 is fixedly provided at the bottom of the sliding seat 105, and a plurality of compression springs 107 are fixedly connected at equal distances to the top of the sliding seat 105; a positioning post 108 is fixedly connected to the top of the housing 101, and a plurality of winding blocks 109 are fixedly connected at equal distances to the opposite sidewalls of the positioning post 108.

[0029] In practice, a sliding seat 105 connected to a compression spring 107 is provided in the positioning sleeve 104. When the restraint assembly is clamped on the patient's arm, the compression spring 107 can compress the sliding seat 105 and the sterile cotton pad 106 to press the position of the infusion needle, thereby preventing mentally unstable patients or those suffering from agitation from accidentally touching and dropping the infusion head during infusion, which would cause infusion failure.
