Description

Technical Field

[0001] The utility model relates to the technical field of shoulder supports for preventing shoulder joint dislocation, and particularly relates to a device for preventing shoulder joint dislocation. Background Art

[0002] As one of the most common acute and chronic diseases in China, stroke is characterized by high incidence, high mortality, and high disability rate. Shoulder subluxation is a common complication of hemiplegia after stroke. The incidence of shoulder subluxation in patients after stroke is 7 - 81%, and 73% in the acute phase. Shoulder subluxation can also cause adhesive capsulitis, which can cause shoulder pain and increase over time. Therefore, patients with acute stroke should immediately start active management and rehabilitation of shoulder subluxation to restore upper limb function. The main causes of its occurrence are the downward rotation of the scapula caused by the paralysis, spasm of the muscles around the scapula, and the influence of the erector spinae muscles, etc. Among them, the hypofunction of the muscles around the shoulder joint mainly composed of the supraspinatus muscle and the deltoid muscle, and the relaxation, damage, and long-term stretching of the shoulder joint capsule and ligaments.

[0003] In clinical practice, for stroke patients who need to lie in bed for rehabilitation treatment, arm slings are often used to assist upper limb rehabilitation treatment to prevent shoulder subluxation. However, due to incorrect placement of the soft pillow or incorrect wearing position of the shoulder support for the patient, incorrect holding methods by the caregiver, or inappropriate self-training by the patient, when the patient performs displacement and rehabilitation training, due to excessive swinging of the patient's elbow, and the patient and the caregiver cannot detect it in time, shoulder subluxation is likely to occur. After subluxation, the function is limited. Due to the inability to detect it in time, it will bring great pain to the patient, not only affecting the patient's daily living ability, but also possibly causing serious consequences such as pain and muscle atrophy, resulting in poor quality of life for the patient, negative rehabilitation mood, and seriously affecting the rehabilitation process. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiency that the patient cannot detect the excessive swing of the elbow in time during the rehabilitation process in the prior art, and provide a device for preventing shoulder joint dislocation.

[0005] In order to achieve the above purpose, the embodiment of the utility model specifically adopts the following technical scheme: A device for preventing shoulder joint dislocation, including a shoulder support that can be bound to the upper limb of the human body. The shoulder support includes a shoulder part, a large arm part, and a small arm part. A strap is arranged on the shoulder part of the shoulder support and is fixed through the opposite axilla. An equipment bag is arranged on the upper part of the shoulder support. A base fixedly connected to the shoulder support is arranged inside the equipment bag. A variable resistor is arranged on the base. A position sensing device is arranged at the input end of the variable resistor. The working part of the position sensing device is arranged along the length direction of the upper limb.

[0006] Further, the shoulder rest is entirely made of fabric, and a magic tape is provided on the outer side of the shoulder rest. The shoulder, upper arm part, and forearm part of the shoulder rest are wound around the outside of the upper limb and adhered.

[0007] Further, the base is a plastic part bonded to the shoulder of the shoulder rest. The variable resistor is a rotary resistor, and the position sensing device is connected to the rotating shaft on the rotary resistor.

[0008] Further, the position sensing device is a wound spring box that can rebound, and the working part of the wound spring box is a pull rope.

[0009] Further, the pull rope is movably connected to the outside of the shoulder rest through a limiting device. The limiting device is a fixed ring provided on the outer side of the shoulder rest. The pull rope passes through the fixed ring and its end is fixed to the forearm part.

[0010] Further, three groups of the wound spring box and the pull rope are provided on the dorsal side of the upper limb.

[0011] Further, a cloth bag for accommodating a support member is provided on the outer sides of the upper arm part and the forearm part of the shoulder rest.

[0012] Further, an alarm for emitting a prompt sound and a power source are provided inside the equipment bag.

[0013] The beneficial effects of the embodiments of the present utility model are as follows: The shoulder rest is composed of a shoulder part, an upper arm part, and a forearm part, and each part is designed with fabric. When in use, it is wound around the upper limb of the human body and adhered through the outer magic tape, which is convenient for disassembly. Snap buttons are installed on the outer sides of the shoulder and the upper arm, and between the upper arm and the forearm. The movement angles between the two are restricted through the connecting cloth belt and the snap buttons to ensure the use effect. The position sensing device uses a wound spring box that can rebound, and its working part is a pull rope. When the upper limb moves, the pull rope will move accordingly, thereby driving the rotation of the rotating shaft of the wound spring box, and further changing the resistance value of the variable resistor. By setting the alarm range of the resistance value, the movement angle range of the upper limb can be limited, preventing the patient from making excessive movements without awareness, reducing the risk of shoulder joint dislocation, and assisting the patient in treatment and recovery.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0019] See Figures 1 to 3 , an embodiment of the present invention discloses a device for preventing shoulder joint dislocation, mainly including a shoulder support that can be bound to the upper limb of the human body. The shoulder support is composed of a shoulder 301, an upper arm 302, and a forearm 303, and each part is designed with fabric. When in use, it is wound around the upper limb of the human body and adhered through the outer magic tape, which is convenient for disassembly. The design of these three parts aims to fully cover and support the upper limb to provide stable support force. And snap fasteners 101 are installed on the outer sides of the shoulder 301 and the upper arm 302, and between the upper arm 302 and the forearm 303. The snap fasteners 101 are connected through a connecting cloth strap 102 to limit the movement angle between each pair to ensure the use effect.

[0020] Regarding the setting of the shoulder 301, a binding strap 1 is specially designed. The binding strap 1 passes through the opposite armpit for fixation to ensure that the shoulder support can be firmly bound to the upper limb. It can be used unilaterally or two can be used to fix both upper limbs on both sides to prevent shoulder joint dislocation on both sides and promote the recovery of patients.

[0021] In addition, an equipment bag 2 is also provided on the upper part of the shoulder support for accommodating various equipment mentioned later. A base 203 fixedly connected to the shoulder support is arranged inside the equipment bag 2. The base 203 is made of plastic parts and is fixedly connected to the shoulder 301 of the shoulder support by an adhesive method. A variable resistor 205 is arranged on the base 203 for sensing the position change of the upper limb. In order to realize the position sensing function, a position sensing device is arranged at the input end of the variable resistor 205 in this embodiment. The working part of the position sensing device is arranged along the length direction of the upper limb so as to be able to sense the position change of the upper limb in real time and give an alarm through a warning device to remind the patient and the caregiver to correct it to prevent the phenomenon that the patient causes shoulder joint dislocation due to large-amplitude placement and incorrect placement posture of the upper limb.

[0022] In specific implementation, the position sensing device adopts a winding spring box 204 that can rebound. Its working part is a pull rope 201. The pull rope 201 of the winding spring box 204 is movably connected to the outside of the shoulder rest through a limiting device. The limiting device is a fixed ring 202 arranged on the outer side surface of the shoulder rest. The pull rope 201 passes through the fixed ring 202 and its end is fixed to the forearm part 303. When the upper limb moves, the pull rope 201 will move accordingly, driving the rotation of the rotating shaft of the winding spring box 204, and then changing the resistance value of the variable resistor 205. By setting the alarm range of the resistance value, the movement angle range of the upper limb can be limited, thereby assisting the patient's treatment and recovery.

[0023] To improve the accuracy and stability of sensing, in this embodiment, multiple groups of winding spring boxes 204 and pull ropes 201 are arranged on the dorsal side of the upper limb. These devices are respectively located on the dorsal sides of the shoulder 301, the upper arm part 302, and the forearm part 303, capable of comprehensively covering the length range of the upper limb and improving the sensitivity of position sensing. In addition, cloth bags for accommodating support members are also arranged on the outer sides of the upper arm part 302 and the forearm part 303 of the shoulder rest. These cloth bags can add support members as needed, such as sponge pads, steel plates, etc., to provide additional support force and enhance the stability and comfort of the shoulder rest.

[0024] Inside the equipment bag 2, an alarm for emitting a prompt sound and a power supply are also provided. When the position sensing device senses an abnormal change in the position of the upper limb, the alarm will emit a prompt sound to remind the user to pay attention. The power supply provides power support for electronic devices such as the alarm and the variable resistor 205.

[0025] During specific use, the user only needs to bind the shoulder rest to the upper limb, fix the position through the strap 1, and then connect the equipment in the equipment bag 2 to the power supply and turn on the alarm. When an abnormal change occurs in the position of the upper limb, the position sensing device will sense this change and transmit the signal to the alarm through the variable resistor 205, causing it to emit a prompt sound. After hearing the prompt sound, the user can adjust the position of the upper limb in time to avoid the occurrence of shoulder joint dislocation, assist the patient's rehabilitation, and improve the rehabilitation effect.
