Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of rehabilitation training, and particularly relates to a device for enhancing upper and lower limb movement of bedridden patients. BACKGROUND

[0002] Upper and lower limb movement is of great significance and has many remarkable advantages for bedridden patients. As is known, bedridden patients are prone to disuse atrophy due to a lack of effective physical activity for a long time. Regular upper and lower limb movement can continuously stimulate muscle fibers, so that the muscle fibers maintain certain tension and activity, thereby significantly slowing down the process of muscle atrophy. For example, simple upper limb fist clenching and stretching and lower limb lifting and lowering can activate muscle cell activity to a certain extent.

[0003] Secondly, such movement has remarkable effects on promoting blood circulation. When lying in bed, the blood circulation of the patient's limbs becomes relatively slow. However, the moderate movement of the upper and lower limbs can effectively promote blood return to the heart, effectively prevent blood accumulation in the lower limbs and other parts, and greatly reduce the risk of thrombosis. This is crucial for the health of the patient's body, just like injecting a source of vitality into the body's blood circulation system.

[0004] In addition, movement is indispensable to maintaining the flexibility of joints. Regular movement of the upper and lower limb joints, such as flexion, extension and rotation, can effectively prevent joint stiffness and contracture, and ensure that the joints always maintain normal range of motion. This undoubtedly lays a solid foundation for the patient to recover normal activity ability in the future and creates favorable conditions for the recovery of body function.

[0005] In addition, from the psychological aspect, upper and lower limb movement also has a positive impact. During the movement, the patient can truly feel the mobility of his body, thereby enhancing the sense of self-control and effectively reducing anxiety and helplessness caused by long-term bedridden. This positive psychological change also has an irreplaceable promoting effect on the patient's recovery.

[0006] However, the reality is that bedridden patients often do not get out of bed, such as patients with hemiplegia, usually face the difficulty of getting out of bed, even if they cannot move half of their body, but the other half of the body usually still has some activity, long-term lying in bed will undoubtedly have many adverse effects on the patient's body, and the patient also urgently needs to assist in exercising the other half of the body during the rehabilitation period. Obviously, bedridden patients generally cannot get out of bed by their own strength, so they cannot independently exercise effectively on the bed. In view of this, it is particularly necessary and has important practical significance to design a device for strengthening the upper and lower limb movement of bedridden patients. Such a device can provide practical exercise assistance for bedridden patients, help them better perform upper and lower limb movement, promote physical rehabilitation, and improve the quality of life.
