Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a pipeline fixing clamp. Background Art

[0002] During hemodialysis, some patients will unconsciously move their arms for various reasons. This is a very dangerous action because the blood pump of the dialysis machine runs at a speed of 250 mL-300 mL. If the puncture needle slips, the consequences will be unimaginable. Therefore, it is crucial to fix the hemodialysis pipeline.

[0003] Medical staff have tried various methods: for example, using hemostatic forceps to clamp the bed sheet to fix the tubing, having dialysis patients hold the hemodialysis tubing with their own hands, sticking the tubing to the bed sheet with tape, or wrapping the tubing with a bed sheet and clamping it with a vascular clamp, etc. However, none of them can achieve the desired effect, because the hemostatic forceps need to be cleaned, wiped and disinfected, which is labor-intensive and economically costly; medical adhesive patches are used for fixing, and the tape is not cleaned thoroughly, which will cause stains on the bed sheet, and the dialysis tubing is relatively heavy and not firmly fixed; the patient holds the dialysis tubing with his own hands, and the dialysis time is as long as 4 hours. When the patient falls asleep, he may unconsciously loosen the tubing in his hand, causing the two tubings to fall down due to gravity, pulling out the puncture needle, and causing the puncture needle to fall off; therefore, it is necessary to design a fixing clamp that can firmly fix the dialysis tubing and is easy to use. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the existing technology, the purpose of the present invention is to provide a pipeline fixing clamp, which effectively solves the problems of poor fixing effect and high economic cost of the existing method of fixing dialysis pipelines.

[0005] The technical solution is as follows: the utility model includes an upper splint, the lower side of the upper splint is hingedly connected to the lower splint via a pin shaft, a torsion spring is mounted on the pin shaft, one end of the torsion spring contacts the upper splint and the other end contacts the lower splint, the upper splint is provided with two left and right opposite placement grooves, the placement grooves include two straight grooves in the front and rear directions, the opposite ends of every two adjacent straight grooves are connected via a transverse groove, the connection between the transverse groove and the straight groove is an arc shape, each straight groove is connected with a slide groove on the left and right sides, a clamping block that can move left and right is provided in the slide groove, a semicircular groove is provided on every two adjacent clamping blocks, the openings of the two adjacent semicircular grooves are opposite and can form a circular shape, the upper end faces of every two adjacent clamping blocks are inclined surfaces, and the two adjacent inclined surfaces form an inverted figure eight shape.

[0006] Compared with the prior art, the present invention has the following beneficial effects.

[0007] 1. The utility model has an ingenious structure and is easy to use. An upper splint and a lower splint are provided, and a placement groove is provided on the upper splint. Every two opposing clamping blocks can move relative to or back to each other. Semicircular grooves and inclined surfaces are provided on the clamping blocks. The dialysis tubing can be fixed by pressing downward, reducing the risk of the puncture needle being pulled out due to the dialysis tubing being pulled.

[0008] 2. The anti-slip pad is set, the connecting part between the straight groove and the horizontal groove is arc-shaped, and a roughened layer is set, which can increase the friction on the outer surface of the dialysis tube and improve the firmness and stability of the fixation of the dialysis tube.

[0014] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 5 It is given, including an upper splint 1, the lower side of the upper splint 1 is hingedly connected to the lower splint 2 via a pin shaft, and a torsion spring is mounted on the pin shaft, one end of the torsion spring is in contact with the upper splint 1 and the other end is in contact with the lower splint 2, and the upper splint 1 is provided with two left and right opposite placement grooves 3, the placement groove 3 includes two straight grooves in the front and rear directions, and the opposite ends of every two adjacent straight grooves are connected via a transverse groove, and the connection between the transverse groove and the straight groove is an arc shape, and each straight groove is connected with a slide groove 4 on the left and right sides respectively, and a clamping block 5 that can move left and right is provided in the slide groove 4, and a semicircular groove 6 is respectively provided on every two adjacent clamping blocks 5, and the openings of the two adjacent semicircular grooves 6 are opposite and can form a circular shape, and the upper end faces of every two adjacent clamping blocks 5 are inclined surfaces, and two adjacent inclined surfaces form an inverted figure eight shape.

[0016] In order to enable the clamping block 5 to move left and right in the slide groove 4, the two adjacent slide grooves 4 are connected to each other on the back side with a moving groove 7, and a moving block 8 is slidably connected in the moving groove 7. One end of the moving block 8 is connected to the bottom of the moving groove 7 through a spring 9 and the other end is fixedly connected to the clamping block 5. A pull rope 10 is fixed to the end of each moving block 8 away from the clamping block 5, and multiple pull ropes 10 can move synchronously.

[0017] In order to enable multiple pull ropes 10 to move synchronously, the upper splint 1 is provided with an inverted T-shaped cylindrical groove located between the two placement grooves 3. A rotating shaft 11 is rotatably connected in the cylindrical groove. A plurality of horizontal rods 12 corresponding to the pull ropes 10 are fixed to the lower end of the rotating shaft 11. The free end of each pull rope 10 is fixedly connected to the free end of the corresponding horizontal rod 12, and a handwheel 13 is fixed to the upper end of the rotating shaft 11.

[0018] In order to enhance the fixing effect of the dialysis tube, an anti-slip pad 14 is fixed on the inner surface of the semicircular groove 6, and the inner surface of the connection between the horizontal groove and the straight groove is a rough layer.

[0019] In order to more firmly fix the upper splint 1 and the lower splint 2 on the bed board or mattress, a plurality of anti-slip grooves 4 are respectively provided on the opposite surfaces of the upper splint 1 and the lower splint 2 .

[0020] In order to better fix the dialysis tube, the inner diameter of the circle formed by the two adjacent semicircular grooves 6 is slightly smaller than the outer diameter of the dialysis tube.

[0021] In order to improve the fixing effect of the dialysis tube, the bottom cross-section of the placement groove 3 is a semicircular arc surface, and the radius of the semicircular arc surface is equal to the radius of the semicircular groove 6.

[0022] When the present invention is in use, the spring 9 is set to be uncompressed, every two adjacent semicircular grooves form a circular shape, and the pull ropes 10 are not wrapped around the multiple horizontal rods 12 in the initial state; when the dialysis pipeline needs to be fixed, the medical staff first squeezes the left ends of the upper splint 1 and the lower splint 2 relative to each other, and the distance between the left ends of the upper splint 1 and the lower splint 2 is reduced and the torsion spring is squeezed, so that the distance between the right ends of the upper splint 1 and the lower splint 2 is increased and the bed board or mattress is clamped, and then the hands are released, and the upper splint 1 and the lower splint 2 are fixed on the bed board or mattress.

[0023] The medical staff first holds a dialysis tube and places the dialysis tube in the inverted eight-shaped shape formed by the inclined surfaces of the two clamping blocks 5 on the rear side, and presses the dialysis tube downward. The dialysis tube squeezes the two inclined surfaces, causing the two clamping blocks 5 to move in opposite directions and compress the spring 9. The distance between the two clamping blocks 5 increases, and the two associated pull ropes 10 become loose, and continue to press the dialysis tube downward. When the minimum distance between the two clamping blocks 5 is greater than the outer diameter of the dialysis tube, the dialysis tube enters the two semicircular grooves, and then the two clamping blocks 5 are reset under the action of the spring 9, and the anti-slip pad 14 is tightly attached to the outer surface of the dialysis tube, and the dialysis tube is fixed between the two clamping blocks 5. Then, the dialysis tube is held and placed in the placement groove 3 along the shape of the straight groove and the horizontal groove, and the other side of the same dialysis tube is fixed between the two clamping blocks 5 on the front side according to the above operation, and the dialysis tube is fixed; similarly, according to the above operation, another dialysis tube is fixed in another placement groove 3 to prevent the dialysis tube from being pulled.

[0024] If the dialysis tube is pulled upward, due to the arrangement of the two semicircular grooves forming a circle, the upward pulling force of the dialysis tube will not cause the two clamps 5 to move away from each other. If the dialysis tubing is pulled along its length or to one side, the rough layer and the anti-slip pad 14 increase the resistance to the movement of the dialysis tubing, effectively preventing the fixed dialysis tubing from moving and improving the fixing effect.

[0025] If the dialysis tubing needs to be released from being fixed, turn the hand wheel 13, and the hand wheel 13 drives the rotating shaft 11 and the horizontal rod 12 to rotate, so that multiple pull ropes 10 are pulled and wrapped around the horizontal rod 12, and the other end of the pull rope 10 pulls the moving block 8, so that the distance between the two adjacent clamping blocks 5 increases and compresses the spring 9. When the distance between the two clamping blocks 5 is greater than the outer diameter of the dialysis tube, the two dialysis tubings are taken out of the placement slot 3 respectively, and the hand wheel 13 is released. The clamping blocks 5, moving blocks 8, pull ropes 10 and the rotating shaft 11 are all reset under the action of the spring 9, which is convenient for fixing the dialysis tube next time.

[0026] In the present invention, the friction force on the outer surface of the dialysis tube is increased to prevent the dialysis tube from moving due to being pulled, without affecting the blood flow effect in the dialysis tube.
