[0002] Hemodialysis, abbreviated as HD, 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 dialysate with a concentration similar to that of the body exchange substances inside and outside the hollow fibers through the principles of diffusion, ultrafiltration, adsorption and convection, thereby removing metabolic waste from the body, maintaining electrolyte and acid-base balance, and removing excess water from the body. The whole process of returning the purified blood is called hemodialysis.
[0003] When undergoing hemodialysis, patients should avoid strenuous exercise, but they can perform some appropriate activities to help improve blood circulation, reduce muscle atrophy and joint stiffness.

[0033] Working principle: when in use, first start the folding motor 210, the folding motor 210 drives the folding threaded column 211 to rotate, and when the folding threaded column 211 rotates, it pushes the drawstring slider 209 to slide away from the folding motor 210 through the thread, and when the drawstring slider 209 slides, it drives the synchronous belt 207 to move, and when the synchronous belt 207 moves, it drives the two synchronous wheels 205 to rotate, and when the synchronous wheels 205 rotate, it drives the two folding shafts 204 to rotate, and the two folding shafts 204 drive the upward-warping bearing plate 301 to warp upward and the downward-warping bearing plate 307 to warp downward, so that the mattress 311 is bent, and then the angle of the headboard 304 is adjusted to ensure that the patient can sit or lie down; Then, the lateral adjustment motor 110 is started to rotate forward, and the lateral adjustment motor 110 drives the roller shaft 111 to rotate through the worm gear reducer 109, thereby realizing the rolling of the moving wheel 112, thereby moving the moving plate 106 close to the headboard connecting plate 105, so that the position on one side of the footboard 309 is cleared; Then, the locking motor 408 is started to rotate forward, and the locking motor 408 drives the locking threaded column 409 to rotate. When the locking threaded column 409 rotates, the meshing slider 407 is pulled up to make it disengaged from the meshing gear 405. Then, the retracting and discharging motor 403 is started, and the retracting and discharging motor 403 drives the retracting and releasing shaft 404 to rotate. The retracting and releasing shaft 404 drives the retracting and releasing support arm 411 to flip over and place it horizontally, thereby driving the pedal crank 414 to a suitable height. Then, the locking motor 408 is started to rotate reversely, and the locking motor 408 drives the locking threaded column 409 to rotate. When the locking threaded column 409 rotates, the meshing slider 407 is pulled down to make it mesh with the meshing gear 405, thereby ensuring that the angle of the retracting and releasing support arm 411 is fixed. Then, the lateral adjustment motor 110 is started to reverse, and the lateral adjustment motor 110 drives the roller shaft 111 to rotate through the worm gear reducer 109, so as to realize the rolling of the moving wheel 112, so as to move the moving plate 106 away from the bedside connecting plate 105 to ensure that the mattress 311 and the retractable support arm 411 are in the proper position; During exercise, the patient sits or lies on the mattress 311, then steps on the footboard 415, and puts the fixed elastic band 416 on the instep, and then exercises; During resetting, the patient's feet first leave the footboard 415, and then the lateral adjustment motor 110 is started to rotate forward. The lateral adjustment motor 110 drives the roller shaft 111 to rotate through the worm gear reducer 109, thereby realizing the rolling of the moving wheel 112, thereby moving the moving plate 106 close to the bedside connecting plate 105, so that the position on one side of the bedside board 309 is cleared; Then, the locking motor 408 is started to rotate forward, and the locking motor 408 drives the locking threaded column 409 to rotate. When the locking threaded column 409 rotates, it pulls the meshing slider 407 to slide up, so that it is disengaged from the meshing gear 405. Then, the retracting and discharging motor 403 is started, and the retracting and discharging motor 403 drives the retracting and releasing shaft 404 to rotate in the opposite direction. The retracting and releasing shaft 404 drives the retracting and releasing support arm 411 to flip downward to make it vertical, so that the foot crank 414 is stored under the bed. Then, the locking motor 408 is started to rotate reversely, and the locking motor 408 drives the locking threaded column 409 to rotate. When the locking threaded column 409 rotates, it pulls the meshing slider 407 down to make it mesh with the meshing gear 405, so as to ensure that the angle of the retracting and releasing support arm 411 is fixed. Then, the lateral adjustment motor 110 is started to reverse, and the lateral adjustment motor 110 drives the roller shaft 111 to rotate through the worm gear reducer 109, so as to realize the rolling of the moving wheel 112, thereby moving the moving plate 106 to the end of the position away from the bedside connecting plate 105; Finally, the folding motor 210 is started to reverse, and the folding motor 210 drives the folding threaded column 211 to rotate in the opposite direction. When the folding threaded column 211 rotates, it pushes the drawstring slider 209 to slide towards the folding motor 210 through the thread. When the drawstring slider 209 slides, it drives the synchronous belt 207 to move. When the synchronous belt 207 moves, it drives the two synchronous wheels 205 to rotate. When the synchronous wheels 205 rotate, it drives the two folding shafts 204 to rotate. The two folding shafts 204 respectively drive the upward supporting plate 301 to tilt downward and reset, and the downward supporting plate 307 to tilt upward and reset, so that the mattress 311 is straight, and then the angle of the headboard 304 is rotated to ensure that the patient can lie down.
