Description

Technical Field

[0001] The utility model belongs to the technical field of medical nursing equipment, and in particular relates to a device for preventing and treating shoulder joint subluxation. Background Art

[0002] In recent years, with the change of people's lifestyle and the increase of social pressure, the incidence of stroke has increased. Among the surviving patients, up to 86% have disabilities such as motor dysfunction to varying degrees, which seriously affects the quality of life of patients. Post-stroke shoulder pain (PSSP) is one of the common complications, which often occurs 2 weeks to 3 months after stroke. The main clinical manifestations are shoulder pain and limited movement. The patient's upper limb functional exercise and daily living ability are seriously affected, and even the sleep and rehabilitation process are affected. Clinical medicine believes that the pathogenesis of PSSP is shoulder subluxation, muscle spasm and joint capsule contracture, shoulder-hand syndrome and osteoporosis. The treatment is mainly based on good limb positioning, active and passive exercise, and early shoulder-humerus rhythm training. It can improve the range of motion of the shoulder joint, enhance the strength of the shoulder muscles, increase the stability of the shoulder joint, relieve pain, etc., but the functional recovery time is slow.

[0003] Shoulder dislocation is one of the more common complications of stroke. In the early stages of a stroke, the shoulder girdle muscles become flaccid and the muscle tone decreases significantly. The gravity of the upper limbs often causes excessive stretching of the ligaments around the shoulder joint and the glenohumeral joint capsule, which can lead to shoulder subluxation. The incidence of shoulder subluxation in stroke patients is as high as 65%, which seriously affects the quality of life of stroke patients. Clinical studies have shown that early prevention and treatment of shoulder subluxation can promote the recovery of upper limb motor function, accelerate the recovery of upper limb function, better improve patients' ability to take care of themselves in daily life, and improve their quality of life. Usually, to prevent shoulder dislocation, patients use triangular bandages and slings to support the affected upper limb when sitting or standing. However, the triangular bandages and slings are fixed to the neck, which makes the patient feel uncomfortable in the neck and is also prone to contracture deformity of the upper limb, affecting the overall recovery of the patient.

[0004] At present, electrical stimulation is usually used for functional recovery in some patients. A certain degree of electrical stimulation can activate cell activity and make the functional recovery speed faster. Electrical stimulation can be used to stimulate the muscles on the hemiplegic side of hemiplegic patients to promote limb muscle strength recovery. As a physical therapy, electrical stimulation is based on the principle of stimulating nerves, muscles, and joint areas through electrical stimulation to enhance the patient's muscle function, thereby improving muscle activity, promoting muscle strength recovery, preventing muscle atrophy, promoting local blood circulation, and reducing joint swelling rate. Although wearing a shoulder brace can temporarily provide a certain support for the shoulder joint and reduce the degree of subluxation, the weakness of the upper limb muscles of patients after stroke has not been properly treated. Once the shoulder brace is removed, the patient's subluxation is still obvious and there is no substantial improvement. Electrical stimulation therapy has a significant effect on the treatment of shoulder subluxation after stroke. Among them, the supraspinatus and deltoid muscles are the main muscles for shoulder abduction. Electrical stimulation of these two muscles can significantly increase the strength of these two muscles and improve shoulder subluxation. However, due to the different body shapes of different patients, the positions that require electrical stimulation are also different, so it is difficult to adapt to the treatment of affected limbs in different situations. Utility Model Content

[0005] The utility model discloses a device for preventing and treating shoulder subluxation, which is intended to solve the technical problem that the existing device for preventing and treating shoulder subluxation can realize the dual functions of mechanical fixation and electrical stimulation of muscle groups, but cannot adjust the position of electrical stimulation according to the body shapes of different patients during electrical stimulation treatment, making it difficult to apply the device for preventing and treating patients in different situations.

[0006] In order to solve the above-mentioned technical problems, the technical solutions adopted by the present utility model are as follows:

[0008] In the utility model, since the shoulder girdle muscle strength on the hemiplegic side of the stroke patient is lost, the tightening effect on the shoulder joint disappears. At this time, it is impossible to maintain the functional position of the humeral head in the shoulder glenoid cavity by the joint capsule and joint ligament alone, causing the humeral head to shift downward, and may even break through the joint capsule in the lower front and tear the ligament, thereby causing pathological dislocation. The shoulder prevention and treatment pad can make the relaxed shoulder joint after hemiplegia relatively stable, making it difficult for the humeral head to move downward or laterally, and preventing the humeral head from being separated from the glenoid cavity due to the upper limb falling under gravity. The electrical stimulation component can stimulate the nerves or muscles of the patient's shoulder through an electric current of a certain intensity, causing muscle contraction, thereby restoring motor and sensory nerve functions. The shoulder prevention and treatment pad is detachably connected to the electrical stimulation component. Before use, the shoulder prevention and treatment pad is The treatment pad is placed separately from the electrical stimulation component. When the patient's shoulder joint needs to be treated, the electrical stimulation component is first adjusted in position according to the patient's specific situation, and then the shoulder treatment pad is bonded to the electrical stimulation component.

The shape of the semicircular sliding rail fits the patient's arm more closely and facilitates the sliding of the sliding block on the circular sliding rail. The electrode support bar can move back and forth on the patient's arm through the sliding of the sliding block on the circular sliding rail, thereby adjusting the position of the electrode sheet laterally, and can quickly perform prevention and treatment of shoulder subluxation for different patients, adapt to electrical stimulation of the muscles of patients of different body sizes, improve the practicality of the device, and facilitate operation and high flexibility.
