Description

Technical Field

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

[0002] Dialysis treatment is one of the renal replacement therapies for patients with acute or chronic renal failure. During treatment, the dialysis machine is connected to the patient through a treatment tube, and the blood is purified and then returned to the patient.

[0003] The existing patent (publication (announcement) number CN208448255U) provides a design solution that is relatively simple and easy to operate. It is to clamp the clip on the patient's arm, and pass the treatment tube through the fixing ring and fix it with fixing bolts. The overall design is very simple and easy to use. However, according to the details in actual operation, it is found that this design solution has the following defects: 1. The dialysis machine and the patient are not the same, so the angles of the treatment tubes between the patient and the machine are also different. The opening direction of the fixing ring in the solution used in the above patent is fixed and cannot be adjusted. If the treatment tube is forcibly fixed, it will inevitably bend, affecting the treatment tube delivery efficiency during dialysis;

[0004] 2. The fixing ring and the treatment tube in the above solution are fixed by fixing bolts. We know that dialysis treatment usually lasts for a long time, generally about three to four hours or even longer, and the contact point between the bolt and the treatment tube is small. Under long-term squeezing, the tube wall of the treatment tube may be squeezed and broken, which will cause a very serious medical accident. Therefore, long-term squeezing with small contacts has high requirements for the material of the treatment tube, which undoubtedly increases the cost of treatment. In the case of high medical expenses, it will undoubtedly be passed on to patients;

[0005] Therefore, based on the above two shortcomings, I think it is necessary to design a universal pipe fixing clamp that can adapt to the on-site treatment tube arrangement environment, can effectively lock the treatment tube when it is fixed, and will not cause damage to the tube wall; for this purpose, we proposed a dialysis tube fixing clamp. Utility Model Content

[0006] The purpose of the utility model is to provide a dialysis tubing fixing clamp to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dialysis tube fixing clamp, comprising a clamping rod and a tube clamp symmetrically installed on the top thereof;

[0008] The clamping rod is composed of two opposite pressure rods staggered to form a clamp, the clamping opening of the clamp faces the left, and the right side is a pinching handle, a torsion spring is arranged at the intersection of the pinching handle and the pressure rod of the clamping rod, and the side of the pinching handle is provided with anti-slip grooves, and the top surface of the upper pressure rod of the clamping rod is provided with two symmetrical slide grooves, the slide grooves are dovetail damping slide grooves, and a raised sliding column is arranged horizontally in the middle of the slide groove;

[0009] A slider is provided at the bottom of the pipe clamp, the slider is a dovetail slider, and a cylindrical groove is provided at the bottom of the slider corresponding to the sliding column, the pipe clamp is movably clamped in the sliding groove through the slider, a rotating shaft head is provided at the top of the slider, the rotating shaft head is a damping universal ball connector, a mounting base is provided at the top of the rotating shaft head, a circular ring is provided at the top of the base, and an adjusting button is threaded through the left and right sides of the circular ring, and an arc-shaped pressing plate is provided at the end of the adjusting button extending into the circular ring;

[0010] Preferably, the arc-shaped pressing plate is located in the annular shape of the circular ring, and the diameter of the arc-shaped pressing plate is smaller than the diameter of the circular ring;

[0011] Preferably, an auxiliary nut with a convex surface is provided at the connection between the outer side of the ring and the adjusting button;

[0012] Preferably, the outer end of the adjusting button away from the circular ring is provided with a circular handle, and the circular handle is provided with thread particles;

[0013] Preferably, a movable cavity is provided at the connection between the arc-shaped pressure plate and the adjusting button, the adjusting button is inserted into the movable cavity, and a limiting opening is provided at the outer end of the connection between the inserting end and the movable cavity.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The pipe clamp can be adjusted in two positions. One is that it can move left and right in the slide. The combination of the dovetail slide, the slide column and the slider makes the pipe clamp slide more smoothly and reliably. Even during the treatment process, the left and right displacement can be adjusted slightly to adapt to the arrangement angle of the treatment tube.

[0016] Secondly, the pipe clamp can rotate the opening direction of the ring 360 degrees through the universal ball connector, and the direction of the ring can be adjusted according to actual needs. At the same time, an arc-shaped pressure plate is used inside the ring to fix the treatment tube. The relative positions of the two arc-shaped pressure plates can be adjusted by rotating the adjustment knob to meet the needs of different treatment tube diameters; and the arc-shaped pressure plate squeezes and fixes the tube wall more evenly, which can effectively avoid damage to the tube wall during long-term fixation; at the same time, this solution is also simple and easy to operate.

When pinching downward, the clamp opening on the left side opens, and then the clamp opening is clamped on the patient's arm. A torsion spring 2 is arranged at the intersection of the pinching handle of the clamping rod 1 and the pressure rod, which is a torsion spring. After the pinching handle is released, the torsion spring returns to its original position. At this time, The upper and lower pressure rods are clamped on the arm, and the side of the kneading handle is provided with anti-slip grooves 3, which can prevent slipping when kneading. The top surface of the upper pressure rod of the clamping rod 1 is provided with two symmetrical slide grooves 11, and the slide groove 11 is a dovetail damping slide groove, and a raised sliding column 12 is horizontally arranged in the middle of the slide groove 11. The pipe clamp 4 can move left and right in the slide groove 11 to adjust the position through the slider 41. The sliding column 12 makes it more stable when moving, and the damping slide groove has its own friction, and it will not slip or move randomly after moving;

[0026] A slider 41 is provided at the bottom of the pipe clamp 4. The slider 41 is a dovetail slider, and a cylindrical groove is provided at the bottom of the slider 41 corresponding to the sliding column 12. The pipe clamp 4 is movably connected to the sliding groove 11 through the slider 41. A rotating shaft head 42 is provided at the top of the slider 41. The rotating shaft head 42 is a damping universal ball connector. The pipe clamp 4 can adjust the opening direction of the ring 44 by the rotation direction of the rotating shaft head 42. A mounting base 43 is provided at the top of the rotating shaft head 42. A ring 44 is provided at the top of the base 43. Adjustment buttons 45 are threaded through the left and right sides of the ring 44. The end of the adjustment button 45 extending into the ring 44 is provided with an arc-shaped pressing plate 46. The left and right movement of the two arc-shaped pressing plates 46 can adapt to the diameter of the ring 44 clamping different pipes, and the arc-shaped pressing plates can hug and fit tightly against the side wall of the pipe, so that the contact point of the pipe will not be squeezed when the pipe is fixed;

[0027] Furthermore, the arc-shaped pressing plate 46 is located in the ring of the circular ring 44, and the diameter of the arc-shaped pressing plate 46 is smaller than the diameter of the circular ring 44, and the two sets of arc-shaped pressing plates 46 and the circular ring 44 should form a matching concentric circle;

[0028] Furthermore, an auxiliary nut with a convex surface is provided at the connection between the outer side of the ring 44 and the adjusting knob 45, which makes the knob more stable when turned;

[0029] Furthermore, a circular handle is provided at the outer end of the adjusting button 45 away from the circular ring 44, and thread particles are provided on the circular handle. The thread particles increase the friction force and also provide a better hand feel.

[0030] Furthermore, a movable cavity is provided at the connection between the arc-shaped pressure plate 46 and the adjusting button 45, and the adjusting button 45 is inserted into the movable cavity, and a limiting opening is provided at the outer end of the connection between the plug-in end and the movable cavity. The adjusting button 45 rotates in the movable cavity, and when the bolt of the adjusting button 45 moves left and right, the arc-shaped pressure plate 46 is driven to move together.

[0031] Working principle: In practical application, the clamping rod 1 is clamped on the patient's arm, and the pipe clamp 4 is adjusted according to the relative position of the machine and the intubation site of the patient. The pipe clamp 4 can move left and right in the slide 11. The pipe clamp 4 can also adjust the opening direction of the ring 44 by rotating the shaft head 42, and then the treatment tube is passed through the ring 44, and the adjustment knob 45 is rotated to make the arc pressure plate 46 close to and fix the treatment tube. The arc pressure plate 46 can better fit the tube and will not cause contact extrusion and puncture; the sliding column 12 set in the slide 11 makes the pipe clamp 4 move more smoothly and will not shake back and forth. The adjustability of the pipe clamp 4 can well solve the problem of the inconvenience of the angle of the treatment tube between the machine and the patient when in use, and avoid accidents caused by the treatment tube being bent.
