Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a shoulder joint brace. Background Art

[0002] Shoulder joint diseases occupy an important position in sports medicine. Shoulder joint injuries include rotator cuff injuries, shoulder dislocations, fractures, etc. For rotator cuff injuries, the movement of the shoulder joint depends on the traction and coordination of the muscles. The rotator cuff thickens the tendons around the shoulder joint to surround the proximal part of the humerus. The rotator cuff can transmit muscle strength to the bone to produce movement. Therefore, rotator cuff degeneration or external force can cause rotator cuff injuries. For example, minor trauma in the elderly and accidental injuries in young people can cause rotator cuff injuries. Rotator cuff injuries are mainly repaired through surgery to suture the damaged rupture. After surgery, the rotator cuff needs to be fixed to repair the rotator cuff. Generally, it takes about 3 months to fix it with a brace. Shoulder dislocation refers to dislocation, that is, the change of the normal position of the joint. The main injury of dislocation is soft tissue injury around the joint. If it is not properly treated, it can develop into habitual dislocation, that is, repeated dislocation. The initial injury of shoulder dislocation is a severe tear of the joint capsule around the shoulder joint and loose soft tissue under traumatic conditions. Patients with repeated dislocations still have this looseness. Therefore, the main method of treatment is to tighten and overlap the joint capsule for repair. There are even cases where repeated dislocations cause bone wear, so bone surgery is required. After this bone surgery, the shoulder needs to be fixed to allow tissue growth and healing. This process requires the use of a brace for fixation, which generally takes about 3 months. Fractures around the shoulder joint mainly include: surgical neck fracture of the humerus, anatomical neck fracture of the humerus, proximal humerus fracture, scapula fracture, clavicle fracture, etc. The treatment of these fractures, whether conservative or surgical, requires brace fixation after surgery, especially for conservatively treated patients, because plaster fixation is not possible at this site, so the brace becomes the most important and most commonly used tool.

[0003] Therefore, the shoulder brace has become an auxiliary fixation medical tool that patients with shoulder joint injuries must wear after surgery, and it plays a very important role in the patient's postoperative recovery. The wound after shoulder joint surgery is usually accompanied by symptoms such as swelling and fever. During the recovery process, as the wound changes, the swelling degree and limb temperature of the affected limb will also change. For example, after the swelling subsides, the brace fixation becomes loose, and the swelling increases, resulting in the brace fixation becoming tighter. If the tightness of the brace cannot be adjusted in time according to the changes in the affected limb, it will affect the surgical effect and the postoperative rehabilitation process: if the fixation is too tight, it will affect the blood return of the limb and cause swelling of the limb distal to the brace. If the compression cannot be relieved in time, tissue edema will continue to increase and cause necrosis of muscle blood vessels and nerves; if the fixation is too loose, the patient cannot be effectively fixed, and stable conditions cannot be created for wound healing. In severe cases, it may even cause inflammation to intensify, collision and friction lead to severe pain, muscle atrophy, etc. During the use of the existing shoulder brace, the affected limb will be wrapped by the brace and cannot be disassembled at will. The tightness of the brace cannot be adjusted in time, which is not conducive to later rehabilitation training. Summary of the invention

Air holes are provided on the outer cover 11 for air intake and exhaust.

[0027] The air pump 4 is connected to a power supply device, which supplies power to the air pump 4, the control mainboard 3 and other electronic components. Specifically, the power supply device includes a power supply battery, which is connected to the air pump 4 and is equipped with a charging interface module 7. Preferably, the power supply battery is a lithium battery 8, which can be recharged and used repeatedly, thereby improving the convenience of using the shoulder joint brace.

[0028] In this embodiment, the outer side of the shoulder joint arc-shaped guard plate 1 is an arc-shaped convex surface, and the inner side of the shoulder joint arc-shaped guard plate 1 is an arc-shaped concave surface adapted to the human torso. The inflatable and deflated airbag 2 fits the arc-shaped concave surface with each other, so that the inflatable and deflated airbag 2 and the shoulder joint maintain appropriate pressure, and the tightness of the brace is appropriate to improve the patient's comfort.

[0029] Specifically, the shoulder joint arc-shaped guard plate 1 includes an upper arc-shaped plate body and a lower arc-shaped plate body, the upper arc-shaped plate body and the lower arc-shaped plate body are connected by an arc transition, the upper arc-shaped plate body is arranged at the top of the shoulder joint, and the lower arc-shaped plate body is arranged at the outside of the arm. The first fixing structure is arranged on the upper arc-shaped plate body, and the second fixing structure is arranged on the lower arc-shaped plate body to achieve the fixation of the shoulder joint brace.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, the first fixing structure includes a first surrounding fixing strap 9, one end of which is connected to the upper arc-shaped plate, and the other end of the first surrounding fixing strap 9 is passed through the armpit of the human body and then connected to the upper arc-shaped plate. The first surrounding fixing strap 9 is passed through the armpit of the human body longitudinally, so that the first surrounding fixing strap 9 longitudinally fixes the shoulder joint arc-shaped guard plate 1.

[0031] Wherein, the second fixing structure includes a second surrounding fixing strap 10, which is mounted on the human arm, and both ends of the second surrounding fixing strap 10 are connected to the lower arc-shaped plate. Preferably, two second surrounding fixing straps 10 are provided on the lower arc-shaped plate, and the heights of the two second surrounding fixing straps 10 are different. The two second surrounding fixing straps 10 are laterally mounted on the arm, so that the second surrounding fixing straps 10 laterally fix the arc-shaped guard plate 1 of the shoulder joint. Through the arrangement of the first surrounding fixing strap 9 and the second surrounding fixing strap 10, the brace can be stably fixed on the shoulder joint.

[0032] In one embodiment, a plurality of temperature detection devices are provided at intervals on the surface of one side of the inflatable and deflated airbag 2 close to the human shoulder joint. The temperature detection device uses a temperature sensor, and the temperature sensor is connected to the control main board 3, and the control main board 3 is connected to an alarm.

[0033] The present invention provides a modular adjustable brace with pressure sensors and temperature sensors for intelligently monitoring the shoulder joint, thereby solving the problem that the affected limb cannot be monitored in real time after the brace is worn, and can send out an alarm signal when the brace is too tight, too loose, or the temperature of the affected limb is abnormal, and timely adjust the fixed state of the brace by inflating the airbag, so as to realize 24-hour real-time monitoring of the healing and change of the postoperative wound of the shoulder joint, that is, under the real-time monitoring of the pressure sensor and the temperature sensor, the following functions are realized:

[0034] 1. Track the postoperative / treatment / rehabilitation effect of shoulder joint: real-time detection / monitoring of biological data of affected limb;

[0035] 2. Timely warning: alarm functions for abnormal situations such as abnormal pressure values ​​and abnormal temperature values ​​can be used to adjust the fixation of the brace in time to avoid complications / disability and ensure the fixation effect.

[0036] The mechanism of action is described as follows:

[0037] 1. Sensor detection: First, pressure sensors and temperature sensors need to be integrated into the shoulder brace to monitor the pressure changes between the brace and the shoulder joint caused by the patient's activities and posture changes.

[0038] 2. Data processing: The data collected by the pressure sensor and the temperature sensor are sent to the control main board 3, and the control main board 3 deflates or inflates the inflatable airbag 2 according to the data monitored by the sensor.

[0039] 3. Inflation control: Once the control motherboard 3 determines that inflation is needed to provide additional support or stability, it will send a signal to the built-in air pump 4 to increase the gas pressure in the inflatable and deflated airbag 2.

[0040] 4. Deflation control: When it is necessary to reduce support or release pressure, the control main board 3 will send a signal to the exhaust valve to deflate the inflatable airbag 2 to reduce support or pressure.

[0041] 5. Feedback and adjustment: The control main board 3 has a feedback mechanism, which can adjust the inflation degree of the inflatable and deflated airbag 2 in real time according to the patient's posture and activity changes to ensure that the inflatable and deflated airbag 2 provides optimal support and comfort for the shoulder joint.

[0042] Compared with the prior art, the present invention has the following advantages:

[0043] 1. Personalized support: The inflatable and deflated airbag 2 can provide personalized support based on the patient's specific needs and activity level. By adjusting the inflation level of the inflatable and deflated airbag 2, the brace can provide appropriate support and stability to help patients perform daily activities comfortably.

[0044] 2. Dynamic adjustment: The inflation level of the inflatable and deflated airbag 2 can be adjusted in real time according to the patient's posture and activity. This dynamic adjustment can ensure that the brace maintains the best support effect, whether the patient is stationary or in motion.

[0045] 3. Improved treatment effect: The shoulder brace combined with the inflatable and deflated airbag 2 can provide more effective treatment effect. By providing customized support, the brace can help treat shoulder diseases and injuries and promote the recovery process.

[0046] 4. Enhanced comfort: The inflated and deflated airbag 2 can adjust the hardness and shape of the brace according to the patient's comfort needs. This personalized adjustment can improve the patient's comfort, reduce discomfort, and enhance the ability to wear the brace.

[0047] 5. Monitoring function: The inflatable and deflated airbag 2 is usually integrated with sensors to monitor the patient's posture, activity level, and adaptability to the brace. This monitoring function can provide important data to help doctors understand the patient's recovery.

[0048] The present invention solves the problems of conventional shoulder joint braces such as the inability to standardize the tightness during wearing, resulting in poor wearing comfort and inability to ensure the fixation effect. It avoids the defects of a brace that is too tight, causing discomfort to the patient and easily affecting the blood circulation of the affected limb, and a brace that is too loose, causing the inability to effectively fix the shoulder joint, affecting the surgical treatment effect and slowing down the recovery process.
