Description

Technical Field

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

[0002] Hemodialysis is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains blood from the body to the outside of the body through a dialyzer composed of countless hollow fibers. The blood and an electrolyte solution (dialysate) containing electrolytes at concentrations similar to those in the body are exchanged inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection. There are many pipe connections during hemodialysis, which need to be fixed.

[0003] However, the existing hemodialysis tubing is fixed to the bedside by a tube clamp. When the patient is not conscious, the arm is not restrained. After falling asleep, the arm is easily bent and swollen due to the inertia of the human body, and the needle may be pulled out by mistake, which may easily cause safety hazards. In addition, it is not easy to adjust the position of the hemodialysis tubing through the tube clamp, and the fixed position of the tubing is limited, and the stability is poor. Utility Model Content

[0004] The utility model aims to provide a hemodialysis tube fixing device, which can restrain the patient's hemodialysis arm to prevent the risk of arm bending, needle swelling, and accidental needle removal, and can adjust the fixed position of the hemodialysis tube for stable installation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hemodialysis pipeline fixing device, including an arm pad and a pipeline clamp, the interior of the arm pad is an arc-shaped structure, and the first restraint belt, the second restraint belt, the pipeline clamp, and the positioning strap are respectively installed on both sides of the arm pad, and magnetic suction grooves are respectively opened on both sides of the arm pad, and the inner wall of the magnetic suction groove is slidably connected with a magnetic slider, the first restraint belt, the second restraint belt and the pipeline clamp, The positioning strap is respectively fixedly installed on the outside of the magnetic slider, the ends of the first restraint belt and the second restraint belt are respectively sewn with Velcro, and one end of the positioning strap is respectively sewn with an adjustment buckle and an adjustment belt, and the pipeline clamp is used to clamp and position the pipeline.

[0006] Preferably, a soft pad is bonded inside the arm pad.

[0007] Preferably, the outer side of the first strap is sewn with a fleece-surface Velcro, the inner side of the second strap is sewn with a hook-surface Velcro, and the second strap is adhered to the outer side of the first strap via the hook-surface Velcro.

[0008] Preferably, the inner wall section of the magnetic chute and the magnetic slider are both T-shaped structures, and the magnetic slider is slidably engaged in the magnetic chute.

[0009] Preferably, the magnetic sliding block and the inner side wall of the magnetic sliding groove are matching magnetic structures.

[0010] Preferably, the adjustment buckle and the adjustment belt are used to position the arm pad.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The arm pad of the utility model can support the patient's arm through the soft rubber pad on the top, and the first and second straps on both sides of the arm pad can adjust the spacing by sliding the magnetic slider at the end, and the positioning straps in the middle of both sides of the arm pad can be connected through the end adjustment buckle and the adjustment strap to position the arm pad on the bed fence, so that the first and second straps can be used to adjust the patient's arm through Velcro to prevent the patient's arm from bending due to human inertia during the hemodialysis process, thereby preventing the safety hazards of needle swelling and accidental needle removal. Compared with the existing hemodialysis tube fixation, the patient's arm can be prevented from bending, avoiding the risk of needle swelling and accidental needle removal.

[0013] The pipe clamps installed on the magnetic sliding blocks in the middle of the magnetic sliding grooves on both sides of the arm pad of the utility model allow the pipe clamps to slide along the magnetic sliding grooves to adjust their positions, so that when the hemodialysis tube is clamped and positioned, the fixed position of the hemodialysis tube can be adjusted. After the arm pad is positioned on the bed by the positioning strap, the pipe clamp does not need to be clamped on the bed, thus avoiding the problem of the pipe clamp being detached due to the displacement of the patient's arm.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] The arm pad 1 can support the patient's arm through the top rubber soft pad 11, and the first and second straps 2 and 3 on both sides of the arm pad 1 can adjust the spacing through the end magnetic sliders 6, and the positioning straps 5 in the middle of both sides of the arm pad 1 can be connected through the end adjustment buckles 51 and the adjustment straps 52 to position the arm pad 1 on the bed fence. In this way, the first and second straps 2 and 3 can adjust the patient's arm through Velcro to prevent the patient's arm from bending due to human inertia during the hemodialysis process, resulting in safety hazards such as needle swelling and accidental needle removal. Compared with the existing hemodialysis tube fixation, the patient's arm can be prevented from bending to avoid the risk of needle swelling and accidental needle removal.

[0025] The pipe clamp 4 is installed on the magnetic slider 6 in the middle of the magnetic slide groove 12 on both sides of the arm pad 1, so that the pipe clamp 4 can slide along the magnetic slide groove 12 to adjust the position, so that when the hemodialysis tube is clamped and positioned, the fixed position of the hemodialysis tube can be adjusted. After the arm pad 1 is positioned on the bed by the positioning strap 5, the pipe clamp 4 does not need to be clamped on the bed, thus avoiding the problem of the pipe clamp 4 being detached due to the displacement of the patient's arm.

[0026] A soft pad 11 is bonded inside the arm pad 1 , and the first restraint belt 2 and the second restraint belt 3 on both sides of the arm pad 1 can be slid to adjust the spacing through the end magnetic sliders 6 .

[0029] Among them, the adjustment buckle 51 and the adjustment belt 52 are used to position the arm pad 1. The positioning straps 5 in the middle of both sides of the arm pad 1 can be connected through the end adjustment buckles 51 and the adjustment belts 52 to position the arm pad 1 on the bed fence.

The patient's arms can be placed on the arm pad 1, and the arm pad 1 can support the patient's arm part through the top rubber soft pad 11. Then, the first binding belt 2 and the second binding belt 3 on both sides of the arm pad 1 can be slid through the end magnetic suction slider 6 to adjust the spacing, so that the first binding belt 2 and the second binding belt 3 can be adjusted to bind the patient's arm through Velcro, preventing the patient from bending his arm due to the inertia of the human body during the hemodialysis process, resulting in swelling of the needle;

[0031] Then, the positioning straps 5 at the middle of both sides of the arm pad 1 can be connected through the end adjustment buckles 51 and the adjustment straps 52 to position the arm pad 1 on the bed fence, thereby avoiding the problem of unclear consciousness of the patient, arm displacement, and needle removal;

[0032] Finally, when clamping and positioning the hemodialysis tube, the pipeline clamp 4 is installed on the magnetic slider 6 in the middle of the magnetic slide groove 12 on both sides of the arm pad 1, so that the pipeline clamp 4 can slide along the magnetic slide groove 12 to adjust the position. After the arm pad 1 is positioned on the bed by the positioning strap 5, the pipeline clamp 4 does not need to be clamped on the bed, thus avoiding the problem of the pipeline clamp 4 being detached due to the displacement of the patient's arm.
