[0045] Working principle:

[0046] During rehabilitation training, the patient extends both feet into the pedals of the rehabilitation training device 206 and pedals and retracts them back and forth (similar to riding a bicycle) to exercise the legs. Before the patient needs to transfer from the wheelchair to the bed, the patient rotates the forward and reverse threaded sleeves 204 to separate the two rounded square tubes 203 from each other, loosens the clamping of the ends of the rounded square tubes 203 on the guide plate 201, and then pushes the rehabilitation training device 206 under the seat 101. The rehabilitation training device 206 rises in height under the action of the guide groove (without dragging on the ground). Then, the forward and reverse threaded sleeves 204 are rotated to make the two rounded square tubes 203 approach each other. The ends of the two rounded square tubes 203 approach each other and clamp the guide plate 201, so that the position of the rehabilitation training device 206 is fixed (when temporarily pushed under the seat 101 of the rehabilitation training device 206, the rehabilitation training device 206 can also be not fixed);

[0047] When installing medical equipment, first insert the placement rack 302 and the movable rack 303 vertically downward into the socket 301, then loosen the first hand-tightening screw 304 to adjust the distance between the placement rack 302 and the movable rack 303, then place the medical equipment between the placement rack 302 and the movable rack 303, and then tighten the first hand-tightening screw 304. The hollow design of the movable rack 303 facilitates the passage of pipelines. The pipelines passing through the placement rack 302 and the movable rack 303 are then passed through the holes between the vertical plate 401 and the restraining bar 402. In this way, the pipelines extending to the patient are rarely exposed, reducing the risk of being pulled by the patient;

[0048] A drainage bag or a urine bag is placed in the placement bucket 7, and the patient's drainage tube is connected to the drainage bag or the urine bag, which clamps the drainage tube in the clamping position of the first catheter clamping plate 6 to restrict movement;

[0049] When adjusting the neck support mechanism 9, loosen the hand-tightening pressure plate 905 to adjust the opening size of the two neck support arc plates 906 to put the patient's neck in the best condition, then tighten the hand-tightening pressure plate 905, and the circular plate of the hand-tightening pressure plate 905 presses the sliding plates of the two neck support arc plates 906 at the same time, so that the positions of the two neck support arc plates 906 are fixed, and then the patient's catheter is clamped into the second catheter clamping plate 907 to fix it, which is convenient and practical. Loosen the second hand-tightening screw 903 to remove the neck support mechanism 9 installed on the chair back 102.

[0050] It should be noted that the above content only illustrates the technical idea of the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, they can make several improvements and modifications without departing from the principles of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
