[0002] Hemodialysis (HD) is one of the kidney replacement treatment methods for patients with acute and chronic renal failure. It involves draining the blood in the body to the outside, passing it through a dialyzer composed of countless hollow fibers. Inside and outside each hollow fiber, blood and an electrolyte solution (dialysate) with a concentration similar to that of the body undergo mass exchange through the principles of diffusion, ultrafiltration, adsorption, and convection to remove metabolic wastes in the body, maintain electrolyte and acid-base balance; at the same time, excess water in the body is removed, and the whole process of returning the purified blood is called hemodialysis.

[0003] Generally, when patients undergo dialysis, they need to place the dialysis arm beside the bed.

[0017] S1: Place the arm;

[0018] S2: Rotate and close;

[0019] S3: Start the motor;

[0020] S4: Slide and massage.

[0021] The present invention has the following beneficial effects:

[0022] 1. In the present invention, when the motor drives the first semi-gear to rotate, the rotation of the first semi-gear will drive the bidirectional threaded rod to rotate through the engaged gear. When the bidirectional threaded rod rotates, the threaded groove on its surface will drive the sliding cylinder to slide back and forth through the insertion rod inside the sliding cylinder during rotation. When the sliding cylinder slides, it will push the semi-ring to slide inside the semi-cylinder through the connecting plate and the inclined plate. When the inclined plate pushes the semi-ring to slide, the fixed rod on the inclined plate will drive the inclined plate to slide up and down inside the semi-ring along the undulating guidance of the circular groove. When the inclined plate slides downward, it will squeeze the semi-circular state of the side wall of the arc-shaped plate. When the arc-shaped plate is squeezed, it will squeeze towards the patient's arm inside the semi-ring. At the same time, the multiple ball bearings on the arc-shaped plate will stop rolling under the clamping of the arc-shaped friction plate. Subsequently, when the inclined plate slides upward, the extrusion of the arc-shaped plate on the patient's arm will disappear. Subsequently, when the semi-ring slides, the arc-shaped plate will achieve the effect of reciprocating massage on the patient's arm through the stopped ball bearings. This intermittent massage action can promote blood circulation in the limbs, reduce the occurrence of limb numbness in patients during long-term dialysis, and thereby improve the comfort of patients during dialysis.

[0023] 2. In the present invention, when the insertion rod on the sliding cylinder slides to the front end of the bidirectional threaded rod, the sliding cylinder will reset and slide back under the continuous rotation of the bidirectional threaded rod. When the sliding cylinder resets, the fixed rod on the inclined plate will slide under the guidance of the straight line on the circular groove. When the fixed rod slides to the straight line on the circular groove, the fixed rod will drive the inclined plate to slide upward inside the semi-ring. When the inclined plate slides upward, it will drive the auxiliary cylinder to slide towards the semi-ring through the connecting plate. When the auxiliary cylinder slides, it will drive the elliptical plate to slide through the support plate. When the elliptical plate slides forward, both ends of the elliptical plate will enter the depressions on the rotating plate. At this time, the two rotating plates will rotate in the strip-shaped groove on the semi-ring under the pulling force of the reset spring between them. When the rotating plate rotates, it will pull the arc-shaped friction plate close to one side of the middle plate to move through the middle plate. At the same time, when the support plate slides forward, the sliding of the support plate will push the arc-shaped friction plate on the side away from the middle plate. At this time, the two arc-shaped friction plates will disengage from several ball bearings. At this time, when the semi-ring resets, the ball bearings will change the sliding friction between the semi-ring and the flexible layer into rolling friction, which can reduce the friction with the flexible layer and reduce the situation where the indwelling needle in the patient's limb is pushed and squeezed due to the generation of sliding friction, and can improve the comfort of patients during dialysis.

[0024] 3. In the present invention, when the first half gear and the second half gear are rotating, the rotation of the second half gear will drive the gear cylinder to rotate. When the gear cylinder rotates, it will drive the internal fan to rotate. At the same time, when the gear cylinder rotates, it will also squeeze the spring plate through multiple internal inclined blocks. When the spring plate is squeezed, it will drive the rotating shaft to rotate. When the rotating shaft rotates, it will wind up the hollow belt. When the hollow belt is wound up, it will gradually contract, so that the hollow belt will be fastened between the surface of the patient's limb and the dialysis tube, thereby reducing the situation that the dialysis tube slips off at the arm due to the sliding of the semi-circular ring on the patient's arm during the sliding massage, thus reducing the external force interference on the dialysis tube, further stabilizing the position of the dialysis tube and reducing the risk of the dialysis tube slipping off.

[0025] 4. In the present invention, when the hollow belt is being wound up, it will be in a relatively loose state at the beginning of winding. Subsequently, with the contact with the patient's arm, the winding of the hollow belt on the rotating shaft will gradually tighten. When the hollow belt is wound up, it will wind around the surfaces of multiple triangular plates. Subsequently, when the hollow belt tightens, it will squeeze the triangular plates. At the same time, the wind generated by the rotation of the internal fan when the gear cylinder rotates will enter the opening inside the rotating shaft and enter the inside of the hollow belt through the gear cylinder and the air outlet pipe to make it expand. Subsequently, when the triangular plates are squeezed, they will push the rotating ring to slide. When the rotating ring slides, it will press the spring plate so that the spring plate disengages from the inclined blocks inside the gear cylinder. At the same time, when the triangular plates are squeezed by the hollow belt, the triangular plates will push the sliding frame towards the gear cylinder through the auxiliary plate. When the sliding frame slides, the opening on its side wall will slide on the surface of the fixed column. At this time, a seal will be formed between the fixed column and the sliding frame. Subsequently, when the sliding frame continues to slide, the fixed column will push the sliding disk when the sliding frame slides. After the sliding disk is pushed, it will squeeze the gas inside the opening of the sliding disk and the rotating shaft. At this time, the gas will be squeezed and enter the hollow belt to make it expand. When the hollow belt expands, it can play a flexible fastening role when fastening the patient's arm and the dialysis tube, reducing the situation of over-squeezing the dialysis tube when the hollow belt is wound up, affecting the flow and transportation of the dialysis fluid, and at the same time reducing the discomfort of pain caused by the patient's arm being squeezed by the dialysis tube due to excessive fastening force, thereby improving the dialysis effect during the patient's dialysis.

[0026] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

When the semi-gear one 104 rotates, it will drive the bidirectional threaded rod 201 to rotate. When the bidirectional threaded rod 201 rotates, it will drive the semi-ring 203 to slide back and forth at the bottom of the flexible layer to achieve the purpose of massaging the patient.

[0057] When the motor 103 drives the first half gear 104 to rotate, the rotation of the first half gear 104 will drive the bidirectional threaded rod 201 to rotate through the gear meshed with it. When the bidirectional threaded rod 201 rotates, the thread grooves on its surface will drive the sliding cylinder 202 to slide back and forth through the insertion rod inside the sliding cylinder 202 during rotation. When the sliding cylinder 202 slides, it will push the semi-circular ring 203 to slide inside the semi-cylindrical tube 102 through the connecting plate 206 and the inclined plate 205. When the inclined plate 205 pushes the semi-circular ring 203 to slide, the fixed rod on the inclined plate 205 will drive the inclined plate 205 to slide up and down inside the semi-circular ring 203 along the undulating guidance of the circulation groove 105. When the inclined plate 205 slides downward, it will squeeze the semi-circular state of the side wall of the arc-shaped plate 204. When the arc-shaped plate 204 is squeezed, it will squeeze towards the patient's arm inside the semi-circular ring 203. At the same time, a plurality of balls on the arc-shaped plate 204 will stop rolling under the clamping of the arc-shaped friction plate 302. Subsequently, when the inclined plate 205 slides upward, the extrusion of the arc-shaped plate 204 on the patient's arm will disappear. Subsequently, when the semi-circular ring 203 slides, the arc-shaped plate 204 will achieve the effect of reciprocating massage on the patient's arm through the stopped balls. This intermittent massage action can promote blood circulation in the limbs, reduce the occurrence of limb numbness in patients during long-term dialysis, and thus improve the comfort of patients during dialysis.

[0058] When the insertion rod on the sliding cylinder 202 slides to the front end of the bidirectional threaded rod 201, the sliding cylinder 202 will reset by sliding back under the continuous rotation of the bidirectional threaded rod 201. When the sliding cylinder 202 is reset, the fixed rod on the inclined plate 205 will slide under the guidance of the straight part of the circular groove 105. When the fixed rod slides to the straight part of the circular groove 105, the fixed rod will drive the inclined plate 205 to slide upward inside the semi-circular ring 203. When the inclined plate 205 slides upward, it will drive the auxiliary cylinder 207 to slide towards the semi-circular ring 203 through the connecting plate 206. When the auxiliary cylinder 207 slides, it will drive the elliptical plate 303 to slide through the support plate 301. When the elliptical plate 303 slides forward, both ends of the elliptical plate 303 will enter the recesses on the rotating plate 304. At this time, the two rotating plates 304 will rotate in the strip-shaped grooves on the semi-circular ring 203 under the tension of the return spring between them. When the rotating plate 304 rotates, it will pull the arc-shaped friction plate 302 on the side close to the middle plate 305 to move through the middle plate 305. At the same time, when the support plate 301 slides forward, the sliding of the support plate 301 will push the arc-shaped friction plate 302 on the side away from the middle plate 305. At this time, the two arc-shaped friction plates 302 will disengage from several balls. At this time, when the semi-circular ring 203 resets, the balls will change the sliding friction between the semi-circular ring 203 and the flexible layer into rolling friction, which can reduce the friction with the flexible layer, reduce the situation that the indwelling needle in the patient's limb is pushed and squeezed due to the sliding friction caused by the sliding of the semi-circular ring 203, and improve the comfort of the patient during dialysis.

[0059] When the semi-gear one 104 and the semi-gear two 402 rotate, the rotation of the semi-gear two 402 will drive the gear cylinder 505 to rotate. When the gear cylinder 505 rotates, it will drive the internal fan to rotate. At the same time, when the gear cylinder 505 rotates, it will also squeeze the spring plate 504 through multiple internal inclined blocks. When the spring plate 504 is squeezed, it will drive the rotating shaft 501 to rotate. When the rotating shaft 501 rotates, it will wind up the hollow belt 404. When the hollow belt 404 is wound up, it will gradually contract, so that the hollow belt 404 will be bound between the surface of the patient's limb and the dialysis pipeline. In this way, when the semi-circular ring 203 slides to massage the patient's arm, the situation that the dialysis pipeline slips at the arm due to the sliding of the semi-circular ring 203 on the arm surface can be reduced, thereby reducing the external force interference on the dialysis pipeline, further stabilizing the position of the dialysis pipeline, and reducing the risk of the dialysis pipeline slipping.

[0060] When the hollow belt 404 is being wound up, at the beginning of the winding process, the hollow belt 404 will be in a relatively loose state. Subsequently, with contact with the patient's arm, the winding of the hollow belt 404 on the rotating shaft 501 will gradually tighten. When the hollow belt 404 is being wound up, it will wind around the surfaces of multiple triangular plates 603. Subsequently, when the hollow belt 404 tightens, it will squeeze the triangular plates 603. At the same time, the wind generated by the rotation of the internal fan when the gear cylinder 505 rotates will enter the opening inside the rotating shaft 501 and pass through the gear cylinder 505 and the air outlet pipe 503 into the inside of the hollow belt 404 to cause it to expand. Subsequently, when the triangular plates 603 are squeezed, they will push the rotating ring 602 to slide. When the rotating ring 602 slides, it will press the spring plate 504 so that the spring plate 504 disengages from the inclined block inside the gear cylinder 505. At the same time, when the triangular plates 603 are squeezed by the hollow belt 404, the triangular plates 603 will push the sliding frame 701 to slide in the direction of the gear cylinder 505 through the auxiliary plate 604. When the sliding frame 701 slides, the opening on its side wall will slide on the surface of the fixed column 703. At this time, a seal will be formed between the fixed column 703 and the sliding frame 701. Subsequently, when the sliding frame 701 continues to slide, the fixed column 703 will push the sliding disk 702 when the sliding frame 701 slides. After being pushed, the sliding disk 702 will squeeze the gas inside the opening of the sliding disk 702 and the rotating shaft 501. At this time, the gas will be squeezed and enter the hollow belt 404 through 503 to cause it to expand. When the hollow belt 404 expands, it can play a flexible binding role when binding the patient's arm and the dialysis tube, reducing the situation of over-squeezing the dialysis tube when the hollow belt 404 is being wound up, which affects the flow and transportation of the dialysis fluid. At the same time, it can also reduce the discomfort of pain caused by the patient's arm being squeezed by the dialysis tube due to excessive binding force, thereby improving the dialysis effect during the patient's dialysis.
