Description

Technical Field

[0001] The utility model belongs to the technical field of dialysis pipeline fixing, in particular to a dialysis pipeline fixing device. Background Art

[0002] Dialysis is a treatment method that allows the components (solutes or water) in body fluids to be excreted from the body through a semipermeable membrane. It is often used in cases of acute or chronic renal failure, accumulation of drugs or other toxins in the body. Commonly used dialysis methods include hemodialysis and peritoneal dialysis. During the dialysis process, since there are many pipes used in the entire hemodialysis process, and the pipes are often relatively long and mostly suspended, medical staff are required to fix the dialysis tubes to various locations such as bed sheets, quilts, and bed guardrails to prevent the dialysis tubes from being pulled and falling off or bending, affecting the normal flow of dialysate and other fluids, thereby affecting the patient's normal hemodialysis and easily causing unnecessary harm to the patient.

[0003] In contrast, a Chinese patent with authorization announcement number CN219332718U discloses a hemodialysis tubing fixing device, comprising a working part fixed to a patient's finger, a limiting card for limiting the position of the dialysis tubing, and a fixing clamp for fixing the dialysis tubing, characterized in that a through hole for the patient's finger to pass through is provided at the center of the working part, and clamping plates for the patient's finger to abut are provided on the left and right sides of the through hole, and the clamping plate is connected to the working part through a spring group, and the working part is provided with an inner groove for the spring group to contract and pop out; and four limiting cards are provided.

[0004] The above patent fixes the dialysis tube by pressing the dialysis tube. Since the dialysis tube is a flexible tube, it is easy to deform. Therefore, the fixing effect of the dialysis tube by pressing alone is not good. Therefore, a new device needs to be designed. Utility Model Content

[0026] In this embodiment: the fixing assembly includes a fixing plate 101, and the first strap 102 and the second strap 104 are symmetrically arranged on both sides of the fixing plate 101. The bottom of the first strap 102 is provided with a card slot 103, and the bottom of the second strap 104 is provided with a card block 105. The first strap 102 and the second strap 104 are both made of nylon elastic bands. The first strap 102 and the second strap 104 are tied to the guardrail through the card block 105 and the card slot 103, and the device is fixed to the guardrail through the fixing plate 101;

[0027] In this embodiment, the clamping assembly includes a slide 201, a positive and negative threaded screw rod 202 is installed in the middle of the slide 201, a knob 203 is arranged on the top of the positive and negative threaded screw rod 202, two clamping frames 204 are symmetrically installed on the slide 201, the clamping frames 204 are slidably connected to the slide 201, two upper clamping blocks 205 are symmetrically installed on both sides of the upper clamping frame 204, and two lower clamping blocks 206 are symmetrically installed on both sides of the lower clamping frame 204. The upper clamping block 205 and the lower clamping block 206 have two second clamping blocks 206 on their opposite sides. A limiting groove 207, the upper clamping block 205 and the lower clamping block 206 are both made of rubber material, and the first limiting groove 207 is semicircular in shape. The two clamping frames 204 are pushed to move oppositely along the slide 201 by rotating the forward and reverse threaded screw rods 202 by the knob 203, and the upper clamping block 205 is separated from the lower clamping block 206. At this time, two dialysis tubes are placed in the first limiting grooves 207 on the two lower clamping blocks 206, and then the knob 203 is rotated to repeat the above steps to make the upper clamping block 205 and the lower clamping block 206 move relative to each other, and the dialysis tube is initially clamped;

[0028] In this embodiment, the locking assembly includes a support plate 301, a locking frame 302 is arranged behind the support plate 301, a locking roller 303 is arranged between the locking frame 302 and the support plate 301, two second limiting grooves 304 are evenly arranged on the locking roller 303, a roller shaft 305 is installed at the center of the locking roller 303, the rear end of the roller shaft 305 extends out of the locking frame 302, and the protruding part is provided with a thread, a locking nut 306 is installed on the threaded part of the roller shaft 305, the locking nut 306 is fitted with the locking frame 302, and the fitting surface is provided with a friction layer to lock the roller shaft 305, the locking frame 302 is in an "L" shape, and the locking frame 302 The locking roller 303 is connected to the support plate 301 by bolts. The second limiting groove 304 is frosted, so that the portion of the dialysis tube between the two lower clamping blocks 206 passes through the second limiting groove 304 from under the locking roller 303, forming a V-shaped path inside the device to improve the fixing effect of the dialysis tube. The locking nut 306 at the rear end of the roller shaft 305 can be loosened to release the locking of the roller shaft 305, so that the locking roller 303 can drive the roller shaft 305 to rotate under the support of the support plate 301 and the locking frame 302, thereby releasing the V-shaped locking of the dialysis tube, so as to pull one end of the dialysis tube to change the fixed position on the dialysis tube.

[0029] Working principle: The two clamping frames 204 are pushed to move in opposite directions along the slide 201 by rotating the forward and reverse threaded screw rods 202 by means of the knob 203, and the upper clamping block 205 is separated from the lower clamping block 206. At this time, the two dialysis tubes are placed in the first limiting grooves 207 on the two lower clamping blocks 206, and the part of the dialysis tube between the two lower clamping blocks 206 is passed through the second limiting grooves 304 under the locking roller 303, forming a V-shaped path inside the device. Then, the dialysis tube is pulled from both ends to tighten the V-shaped part of the dialysis tube between the two lower clamping blocks 206, and the knob 203 is rotated to repeat. The above steps cause the upper clamp block 205 and the lower clamp block 206 to move relative to each other, clamping the dialysis tube. Finally, the first strap 102 and the second strap 104 are tied to the guardrail through the clamp block 105 and the clamping groove 103, and the device is fixed by the fixing plate 101, thereby fixing the dialysis tube; loosening the locking nut 306 at the rear end of the roller shaft 305 can release the locking of the roller shaft 305, so that the locking roller 303 can drive the roller shaft 305 to rotate under the support of the support plate 301 and the locking frame 302, thereby releasing the V-shaped locking of the dialysis tube, so as to pull one end of the dialysis tube to change the fixed position on the dialysis tube.
