Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a pipeline fixer. Background Art
[0002] During hemodialysis, some patients will unconsciously move their arms for various reasons, which 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 very important to fix the hemodialysis line. Medical staff have tried various methods: such as using hemostatic forceps to clamp the bed sheet to fix the line, letting the dialysis patient hold the hemodialysis line with his own hands, sticking the line to the bed sheet with tape, or wrapping the line with the bed sheet and clamping it with a vascular clamp, etc., but none of them can achieve the best effect.
[0003] The existing hemodialysis tubing fixture with Chinese authorization announcement number CN219375640U discloses that the hemodialysis tube body is limited by inserting the clamping column on the first limiting block into the clamping groove on the second limiting block, and the convex column on the clamping column is then inserted into the cylindrical groove, and the hemispherical block is inserted into the hemispherical groove, and the fixing belt is provided, and the fixing belt with the buckle is pulled to buckle the buckle on the fixing belt with the buckle groove at the other end, so that the tightness of the fixing belt can be adjusted according to the thickness of the patient's arm; the utility model has the following defects:
[0004] 1. The dialysis tubing is simply fixed in a straight line in the circular cavity formed by the first stopper and the second stopper. Since the dialysis tubing is a silicone catheter and is relatively soft, when the dialysis tubing is accidentally pulled, the dialysis catheter will be slightly deformed between the first stopper and the second stopper, and there is a risk that the dialysis catheter will shift, causing the puncture needle to be pulled out;
[0005] 2. Use a fixing belt to fix the first limit block and the second limit block on the patient's arm. Since sweat is easily produced where the arm is wrapped by the fixing belt, and each dialysis time is relatively long, sweat is not easily absorbed by the fixing belt, which can easily cause rashes and other discomforts on the patient's skin, affecting the patient's dialysis experience. Utility Model Content
[0006] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide a pipeline fixer, which effectively solves the problem of unsatisfactory fixation effect on dialysis pipelines.
[0007] The technical solution is that the utility model includes a restraining belt, the two free ends of the restraining belt are detachably connected, the middle width of the restraining belt is greater than the width of the two sides, a bottom plate is fixed on the upper middle side of the restraining belt, two left-right symmetrical and inverted S-shaped limiting grooves are provided on the bottom plate, the two free ends of the limiting grooves respectively pass through the front end or the rear end of the bottom plate, a pressure plate is hingedly connected to the right side of the bottom plate, the left end of the pressure plate is detachably connected to the bottom plate, and a plurality of pressure blocks with arc openings downward are fixed to the lower surface of the pressure plate, and the pressure blocks are located above the corners of the limiting grooves or the openings.
[0008] Compared with the prior art, the utility model has the following beneficial effects:
[0009] 1. The utility model has an ingenious structure and is easy to use. The restraint belt is composed of two layers of breathable non-woven fabric and a breathable layer. It has the functions of being soft, breathable and sweat-absorbent, which increases the comfort of the patient's arm and reduces the chance of skin rashes and other discomforts.
[0010] 2. The bottom plate and the limit groove are set in an inverted S shape, and a pressure plate and a pressure block are set. The inner surface of the limit groove and the lower surface of the pressure block are rough surfaces, which increases the resistance and friction when the dialysis catheter is fixed, so that the fixed dialysis catheter will not move, reducing the risk of the puncture needle falling off;
[0011] 3. The locking plate, positioning groove, positioning rod and torsion spring are provided to facilitate fixing the pressing plate on the bottom plate and opening the pressing plate quickly, which is convenient for the operation of medical staff, saves the time of medical staff, improves work efficiency, has wide applicability and is easy to promote and use.

[0020] In order to increase the breathability when used by the patient and improve the patient's comfort, the restraint belt 1 includes two breathable non-woven fabric layers 6 facing each other up and down, and the two breathable non-woven fabric layers 6 are connected via a breathable layer 7.
[0021] In order to enable the free ends of the two restraining belts 1 to be detachably connected, a female Velcro tape is fixed to the outer side of the left end of the restraining belt 1 and a male Velcro tape is fixed to the inner side of the right end.
[0022] In order to realize a hinged connection between the pressure plate 4 and the base plate 2 and facilitate the opening of the pressure plate 4, the right side of the base plate 2 is rotatably connected to two front and rear opposite rotating shafts 8, the opposite ends of the two rotating shafts 8 are respectively fixedly connected to the pressure plate 4, and a torsion spring 9 is mounted on the rotating shaft 8, one end of the torsion spring 9 is in contact with the lower surface of the pressure plate 4 and the other end is in contact with the upper surface of the base plate 2.
[0023] In order to enable the left end of the pressing plate 4 to be detachably connected to the base plate 2, a locking plate 10 is fixed to the left side of the pressing plate 4, and a positioning groove 11 opening forward is provided on the locking plate 10. An inverted L-shaped groove with an opening on the left side and the rear side connected to the positioning groove 11 is provided on the left side of the base plate 2. A positioning rod 12 of the same shape as the inverted L-shaped groove is slidably connected in the inverted L-shaped groove. The rear end of the positioning rod 12 is an inclined surface with a high front and a low rear and can be inserted into the positioning groove 11. The left end of the positioning rod 12 extends out of the positioning groove 11 and its front end is connected to the front side wall of the inverted L-shaped groove via a spring sheet 13.
[0024] In order to increase the fixing effect on the dialysis tube, the inner surface of the limiting groove 3 and the lower surface of the pressing plate 4 are both rough surfaces, and the diameter of the circle formed by the limiting groove 3 and the pressing plate 4 is slightly smaller than the outer diameter of the dialysis tube.
[0025] In order to increase the stability of the bottom plate 2 fixed on the patient's limb, the lower surface of the bottom plate 2 is an arc-shaped surface with the arc opening facing downward.
[0026] When the utility model is in use, the rear end of the positioning rod 12 is inserted into the positioning groove 11, that is, the pressing plate 4 is parallel to the bottom plate 2, and the torsion spring 9 is in the compressed initial state; when the patient's dialysis catheter needs to be fixed, the medical staff places the curved surface of the bottom plate 2 on the patient's limbs (taking the arm as an example), and the two free ends of the restraint belt 1 are respectively passed around the lower side of the patient's arm, and after adjusting the tightness, the Velcro sub-tape is bonded to the Velcro mother tape, so that the bottom plate 2 is fixed on the patient's arm;
[0027] Then the thumb and index finger push the positioning rod 12 forward, the positioning rod 12 moves forward and squeezes the spring sheet 13, after the rear end of the positioning rod 12 is completely out of the positioning groove 11, the pressing plate 4 drives the rotating shaft 8 to rotate clockwise under the action of the two torsion springs 9, that is, the pressing plate 4 swings to the right, the limiting groove 3 is exposed, the positioning rod 12 is released, and the positioning rod 12 is reset under the action of the spring sheet 13, and the medical staff puts the two dialysis tubes into the corresponding limiting grooves 3 according to the shape of the limiting grooves 3;
[0028] Finally, the pressing plate 4 is swung to the left, and the pressing plate 4 drives the multiple pressing blocks 5 to swing counterclockwise and compress the torsion spring 9. The locking plate 10 swings to the left with the pressing plate 4 and squeezes the inclined surface on the rear side of the positioning rod 12, so that the positioning rod 12 moves forward and squeezes the spring sheet 13. When the lower surface of the pressing block 5 is in tight contact with the outer edge of the dialysis tube, the pressing plate 4 swings to a state parallel to the bottom plate 2. At this time, the positioning rod 12 moves backward under the action of the spring sheet 13, and the rear end of the positioning rod 12 is inserted into the positioning groove 11, fixing the pressing plate 4 on the bottom plate 2, thereby fixing the dialysis catheter, preventing the dialysis catheter from being accidentally pulled and causing the needle to fall off, increasing the convenience of medical staff's work, and improving work efficiency.
