Description

Technical Field

[0001] This invention relates to the field of rehabilitation exercise technology, and in particular to a combined arm muscle exercise device. Background Technology

[0002] Hemiplegia, commonly known as paralysis of one side of the body, requires rehabilitation training for patients to prevent muscle atrophy and other phenomena. This usually involves exercises for the patient's limbs to keep them in a state of motion, thus achieving the goal of rehabilitation.

[0003] However, since hemiplegic patients have difficulty performing independent movements, they usually need rehabilitation physicians or equipment to assist them with movement. Current training equipment can usually only perform single-arm exercises, which is difficult to meet the needs of movement in various joints of the limbs. This results in the training effect being singular, requiring patients to use a combination of various training equipment to achieve the goal of rehabilitation training, which increases the cost of training and the burden on patients.

[0010] Beneficial effects

[0011] In this invention, a base, a connecting seat, a take-up roller, an extension plate, a limiting plate, a connecting rod, and a cylinder are provided. The base and connecting seat work together to move the patient's elbow joint, the extension plate and the limiting plate work together to move the patient's wrist joint, and the limiting plate and the connecting rod work together to move the patient's fingers. By combining multiple sets of movements, the patient's elbow, wrist, and fingers can be trained individually or simultaneously according to training needs, allowing the muscles and joints of the entire arm to be trained. This meets the different training needs of patients, eliminates the need for multiple training devices, reduces training costs, and greatly improves training effectiveness.

[0012] Furthermore, by incorporating mounting rods, a fixing frame, a slider, and a massage roller, after training, the two sets of mounting rods can be inserted into the two sets of rectangular grooves at the top of the base. Then, the third motor is activated to drive the lead screw to rotate. The lead screw drives the slider to slide back and forth along the inner side of the fixing frame, thereby causing the massage roller to roll back and forth along the top of the patient's arm. Under the action of the spring on the outer side of the slider, the massage roller fits tightly against the patient's arm, thus providing a reciprocating massage motion during the rolling motion. This helps to accelerate blood circulation in the patient's arm, reduce the degree of muscle atrophy, and bring better rehabilitation training results. When not in use, the mounting rods can be removed to avoid affecting training. The mounting rods can be easily removed for convenient use and storage. Attached Figure Description

The massage roller 406 is rotatably mounted at the bottom of the two sets of slide rods 405, and the outer wall of the massage roller 406 is fixedly provided with a hemispherical protrusion structure in a ring array.

[0032] By adopting the above technical solution, after training, two sets of mounting rods 4 can be inserted into two sets of rectangular grooves at the top of the base 1. Then, the third motor 403 is started to drive the lead screw 404 to rotate. The lead screw 404 drives the slider 402 to slide back and forth along the inner side of the fixed frame 401, thereby driving the massage roller 406 to roll back and forth along the top of the patient's arm. Under the action of the spring on the outside of the slide rod 405, the massage roller 406 fits tightly against the patient's arm, thus performing a back and forth massage action on the patient's arm during the rolling of the massage roller 406. This helps to accelerate the blood circulation of the patient's arm, reduce the degree of muscle atrophy, and bring better rehabilitation training results.

[0033] The specific usage and function of this embodiment: In this invention, during use, the patient's upper arm is placed in the arc-shaped groove at the top of the base 1 and fixed by the first strap 101. The patient's forearm is placed on top of the connecting seat 2. By pulling the connecting seat 2 back and forth, the appropriate position is adjusted. During this process, the transmission rod 201 is simultaneously driven to slide back and forth along the fixed rod 104, so that the fixed rod 104 slides in the through groove on one side of the transmission rod 201. This maintains the connection between the transmission rod 201 and the fixed rod 104 during the adjustment of the position of the connecting seat 2, and is fixed by the second strap 202. Then, place the back of the patient's hand on top of the limiting plate 302 and place the patient's fingers on the connecting rod 303. The patient's fingers are then fixed to the connecting rod 303 by the third straps 304. When performing elbow joint movement, the first motor 103 is activated to rotate the two sets of take-up rollers 102. This causes the connecting seat 2 to move via the rope on the outside of the take-up rollers 102, further pulling the patient's forearm up. After being pulled up, the take-up rollers 102 rotate in the opposite direction, causing the rope to loosen and return to its original position under the weight of the patient's forearm. This process is repeated to complete the entire elbow joint movement. When wrist joint movement is required... The second motor 301, in conjunction with the gear set, drives the limiting plate 302 to rotate at the front end of the extension plate 3. The limiting plate 302 then lifts the patient's palm upwards, thus moving the patient's wrist joint. The second motor 301 drives the reciprocating motion of the limiting plate 302, causing the patient's palm to rise and fall repeatedly, achieving the purpose of wrist joint movement. When finger movement is required, the starting cylinder 306 actuates the rack 307, which slides forward along the guide rail 305. The rack 307 drives the half gear 308, which in turn synchronously drives the connecting rod 303. The outer side of the limiting plate 302 rotates and lifts, which in turn lifts the patient's fingers via the connecting rod 303, causing the patient's fingers to flex and extend. The reciprocating switch action of the cylinder 306 drives the patient's fingers to reciprocate flexion and extension, completing the training process for the patient's fingers. By combining multiple sets of exercises, the patient's elbow joint, wrist joint, and fingers can be trained individually or simultaneously according to training needs, so that the muscles and joints of the entire arm can be trained, meeting the different training needs of the patient. This eliminates the need for multiple training equipment, reduces training costs, and greatly improves the training effect.After training, the two sets of mounting rods 4 can be inserted into the two sets of rectangular grooves at the top of the base 1. The weight of the mounting rods 4 can be increased according to actual use, ensuring that the weight of the mounting rods 4 and the fixing frame 401 exceeds the elastic force of the spring on the outer side of the slide rod 405. Then, the third motor 403 is activated to rotate the lead screw 404. The lead screw 404 drives the slider 402 to slide back and forth along the inner side of the fixing frame 401, thereby causing the massage roller 406 to roll back and forth along the top of the patient's arm. Under the action of the spring on the outer side of the slide rod 405, the massage roller 406 fits tightly against the patient's arm, providing a reciprocating massage during its rolling motion. This helps accelerate blood circulation in the patient's arm, reduces muscle atrophy, and brings better rehabilitation training results. When not in use, the mounting rods 4 can be removed to avoid interfering with training.
