Description

Technical Field

[0001] The present invention relates to the technical field related to medical devices, and in particular to a home-use supine upper limb rehabilitation training device for post-stroke hemiplegia. Background Art

[0002] Stroke is one of the leading chronic diseases causing disability and mortality in adults worldwide, characterized by high morbidity and disability. Most stroke survivors suffer varying degrees of motor dysfunction, with upper limb hemiplegia being one of the most common sequelae. Neurological damage can lead to decreased muscle strength and limited range of motion in the affected upper limb. Without timely and effective rehabilitation training, secondary injuries such as muscle atrophy, joint stiffness, soft tissue contractures, and even deformities can occur, severely impacting daily living abilities and quality of life.

[0003] Currently, the restoration of upper limb function in clinical rehabilitation primarily relies on physical therapy at specialized rehabilitation institutions. However, most patients (especially the elderly) require long-term home convalescence after acute treatment. Existing upper limb rehabilitation training equipment is primarily designed for sitting or standing positions, making it difficult to adapt to bedridden patients. Hemiplegic patients who are bedridden for a long time or have poor physical fitness often cannot adapt to the operating requirements of such equipment. Therefore, it is necessary to design an upper limb exercise device specifically for bedridden patients. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides the following technical solutions: A home-use supine upper limb rehabilitation trainer for post-stroke hemiplegia comprises a backboard, a training arm is rotatably provided on one side of the backboard, the training arm comprises an upper arm board and a lower arm board, the rear end of the upper arm board is rotatably connected to the backboard, and the front end is rotatably connected to the lower arm board; the upper arm board comprises a bottom board and an upper support board, the rear end of the upper support board is rotatably connected to the bottom board, the front end is rotatably connected to the lower arm board, and the bottom board is rotatably connected to the backboard.

[0005] Furthermore, a flexion and extension motor is fixedly provided on one side of the front end of the upper support plate, which drives the forearm plate to rotate through the flexion and extension motor; an arm lifting motor is fixedly provided on the base plate, which drives the upper support plate to rotate through the arm lifting motor; an abduction motor is fixedly provided on the back plate, which drives the base plate to rotate through the abduction motor, thereby driving the training arm to rotate.

[0006] Furthermore, the forearm plate includes a lower support plate and an elastic band. The rear end of the lower support plate is rotatably connected to the upper support plate through a fixed forearm shaft, and the output shaft of the flexion and extension motor is fixedly connected to the forearm shaft; the two ends of the elastic band are respectively fixedly connected to the lower support plate and the upper support plate.

[0007] Furthermore, the upper support plate and the lower support plate are both telescopic structures, and restraint belts are fixedly provided on both sides of the non-extending sections of the upper support plate and the lower support plate.

[0008] Furthermore, the rear end of the upper support plate is rotatably connected to the base plate via a fixed boom shaft, an extension plate is fixedly provided on the side of the back plate, the rear end of the base plate is rotatably connected to the extension plate via a fixed plate shaft, the output shaft of the arm lifting motor is fixedly connected to the boom shaft; the output shaft of the outward extension motor is fixedly connected to the plate shaft.

[0009] Furthermore, a flexible pad is fixedly provided on the back plate.

[0010] Compared with the existing technology, the technical solution of this application has the following beneficial effects: The present invention provides a training arm rotatably arranged on one side of the backboard, and the training arm includes an upper arm board and a lower arm board. The rear end of the upper arm board is rotatably connected to the backboard, and the front end is rotatably connected to the lower arm board. When in use, the backboard is placed on the bed, and the patient leans on the backboard, and the arm is fixed to the training arm by a restraint belt. The lower arm board can be driven to rotate by a flexion and extension motor to drive the lower arm to perform flexion and extension exercises, and the upper support board can be driven to rotate by an arm lifting motor, thereby driving the lower arm board to rotate, realizing synchronous rotation of the patient's upper arm and lower arm, realizing arm lifting movement, and the bottom board is driven to rotate by an abduction motor, thereby driving the training arm to rotate, realizing abduction and adduction exercises of the patient's upper arm, so that bedridden patients can get effective upper limb exercises.
