[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0022] The present application provides a lower limb exercise device for bedridden patients, which is mainly used to solve the problem that vegetative patients or bedridden patients cannot get out of bed and walk for a long time, which will cause a series of adverse consequences, including severe muscle atrophy and weakness, joint stiffness and low immune function, etc. The above adverse consequences will hinder the patient's rehabilitation treatment, causing delayed recovery of the patient, and in severe cases, the recovered patient will be unable to walk independently. The following technical solutions are provided, which will be combined with Figure 1-Figure 4 Make a detailed description:

[0023] A lower limb exercise device for bedridden patients mainly comprises a mounting block 1 mounted on the end of a hospital bed, a connecting frame 2 mounted on the mounting block 1, a device block 3 fixed on the connecting frame 2, a bidirectional motor 4 arranged inside the device block 3, exercise components 5 mounted on both output ends of the bidirectional motor 4, the two exercise components 5 respectively corresponding to the two legs of the patient, the exercise component 5 comprises an L-shaped rod 51 fixed on the output end of the bidirectional motor 4, a rotating rod 52 is rotatably mounted on one end of the L-shaped rod 51, a "Z"-shaped structure is formed between the rotating rod 52 and the L-shaped rod 51, a foot pedal 53 is mounted on one end of the rotating rod 52, an elastic strap 54 is connected between the opposite sides of the foot pedal 53, the elastic strap 54 can fix the patient's foot to the foot pedal 53, the foot pedal 53 drives the patient's lower limbs to move, in specific operation, first Install the mounting block 1 on the foot of the bed and ensure its stability. Then the medical staff or family members fix the patient's feet on the foot pedal 53. Finally, the bidirectional motor 4 controls the two L-shaped rods 51 to rotate, and the rotating rod 52 drives the foot pedal 53 to move, thereby driving the patient's lower limbs to move, which can promote the blood circulation of the patient's lower limbs, effectively prevent or improve diseases such as varicose veins in the lower limbs, and relieve the patient's limb pain. Long-term bed rest will cause muscle atrophy in the patient's lower limbs. The use of this device can effectively prevent and improve muscle atrophy and enhance the strength and endurance of the lower limb muscles. Proper exercise can improve the patient's cardiopulmonary function and enhance the body's immunity and disease resistance. For bedridden patients, rehabilitation is a long and difficult process. This device can provide patients with targeted rehabilitation training and speed up the patient's recovery.

[0024] In this example, see Figure 2 , Figure 3 and Figure 4A controller 31 is installed on the device block 3. The controller 31 can control parameters such as the operating time, operating interval and operating speed of the bidirectional motor 4, which can better drive the patient's lower limb exercise. A rechargeable and dischargeable battery 32 is installed on the device block 3. The battery 32 can power the bidirectional motor 4, thereby driving the two foot pedals 53 to move.

[0025] For further information, see Figure 2 and Figure 3 The foot pedal 53 is in a "U" shape. The sole of the patient's foot is inserted into the foot pedal 53, which can better limit the position of the patient's foot. An arc-shaped baffle 55 is fixed on the foot pedal 53, and the arc-shaped baffle 55 can support the patient's heel to ensure the stability of the fixation between the patient's foot and the foot pedal 53.

[0026] To improve the usability of the device and to accommodate patients of different heights, please refer to Figure 2 and Figure 3 The connecting frame 2 includes a connecting rod 21 fixed on the mounting block 1, and a vertical adjusting rod 22 is movably inserted through the connecting rod 21. The device block 3 is fixed to one end of the adjusting rod 22. The side of the adjusting rod 22 facing away from the mounting block 1 is configured with a plurality of positioning holes 23 distributed in an array. A positioning pin 24 is movably inserted on the connecting rod 21, and one end of the positioning pin 24 is movably inserted into one of the positioning holes 23. By moving the adjusting rod 22, the positions of the two foot pedals 53 can be changed, so that the soles of the patient's feet can be fixed to the foot pedals 53. By inserting the positioning pin 24 into the corresponding positioning hole 23, the adjusting rod 22 can be fixed; the positioning pin 24 is threadedly inserted on the connecting rod 21, and the fixing effect is better.

[0027] For further information, see Figure 2 , Figure 3 and Figure 4 The mounting block 1 is in a "U"-shaped structure and the opening of the mounting block 1 is movably clamped on the side of the bed. A threaded rod 11 is threadedly inserted on the mounting block 1. One end of the threaded rod 11 movably penetrates into the opening of the mounting block 1 and is installed with a pressing plate 12, which is convenient for removal and installation and convenient for installation according to different beds. The opening of the mounting block 1 is clamped on the side of the tail of the bed, and the threaded rod 11 is rotated to drive the pressing plate 12 to move. The pressing plate 12 and one of the inner walls on the opening of the mounting block 1 clamp the bed to ensure the stability of the entire device.
