[0002] With the development of modern medical technology, more and more attention is paid to the importance of postoperative rehabilitation in the treatment of injuries and diseases of the shoulder joint and its surrounding structures. Traditional shoulder abduction braces are mainly used to fix and support the angle of the shoulder joint to protect and support the shoulder joint and arm, especially in the rehabilitation stage after shoulder surgery. However, these braces often lack comprehensive protection and rehabilitation functions for the entire arm and joint.

[0003] Although the designs of existing abduction braces have been diversified, the existing various fixation braces for the shoulder, elbow and wrist joints usually focus on the protection and fixation of a single joint, and it is difficult to fully cover all parts from the shoulder to the hand. This design has low flexibility and limits the application of braces in various scenarios after complex operations, such as postoperative recovery of multiple injuries. In addition, during the entire process of postoperative rehabilitation, patients need to use braces to fix and support the affected area first. When the affected area recovers to a certain extent, patients need to gradually restore the mobility of their arms. Existing braces often lack flexible adjustment mechanisms and cannot balance the needs of joint protection and training and recovery of mobility.

[0004] In order to solve the problem that the existing abduction brace can only fix and support the joints and arms and is too single, a newly designed shoulder abduction brace is needed, which can provide full coverage fixation and support from the shoulder, upper arm, elbow, forearm to wrist and hand; the core goal of the newly designed brace is to provide stable fixation in the early postoperative period to prevent the joints and arms from being injured again during the recovery period; as the rehabilitation progresses, the degree of restriction of the brace can be adjusted to gradually increase the freedom of movement of the shoulder, elbow and wrist joints to meet the rehabilitation training needs at different stages; medical staff are allowed to gradually adjust the range of motion according to the patient's recovery, or the patient can adjust the range of motion of the arm joints according to the formulated training plan and his own recovery feeling; the adjustment function of the shoulder, elbow and wrist joints is particularly important, and the activity angle needs to be gradually released according to different rehabilitation stages to improve the patient's compliance with rehabilitation training and help the patient gradually restore normal joint function.

[0005] In clinical applications, the new shoulder abduction brace can be used for a variety of conditions such as rotator cuff injury, shoulder dislocation, avulsion fracture of the greater tuberosity of the humerus, etc., thereby broadening the application scenarios of existing abduction braces.

[0048] In addition, the surface of the airbag can be made of light and breathable material, which is easy to disassemble and comfortable to wear. It can be used for both static treatment and dynamic rehabilitation exercise.

[0049] The above-mentioned airbag abduction brace 2 has airbags that cover and support the waist, upper trunk, armpits, arms and joints in sections. Figure 2 and Figure 3As shown, the airbags of the airbag abduction brace 2 include a trunk airbag 211, a shoulder joint airbag 22, an upper arm airbag 212, an elbow joint airbag 23, a forearm airbag 213, a wrist joint airbag 24 and a hand airbag 214; the trunk airbag 211 is contoured to match the waist-upper trunk-armpit segment; the shapes of the upper arm airbag 212, the forearm airbag 213 and the hand airbag 214 are contoured to match the shapes of the upper arm, forearm and hand of the armpit-arm segment, and are respectively used to support the inner side of the upper arm, the outer side of the forearm and the outer side of the hand; wherein the air paths of the trunk airbag 211, the upper arm airbag 212, the forearm airbag 213 and the hand airbag 214 are interconnected and constitute the supporting part 21; the air paths of the supporting part 21, the shoulder joint airbag 22, the elbow joint airbag 23 and the wrist joint airbag 24 are respectively connected to the inflation unit 4, and the air pressures are independently adjusted.

[0050] During use, the air paths of the torso airbag 211, the upper arm airbag 212, the forearm airbag 213 and the hand airbag 214 are connected in sequence through the trachea; the air paths of the supporting part 21, the shoulder joint airbag 22, the elbow joint airbag 23 and the wrist joint airbag 24 are respectively connected to the inflation unit 4 through the trachea.

[0051] The specific independent air path connections between the above-mentioned inflatable unit 4 and the supporting part 21, the shoulder joint airbag 22, the elbow joint airbag 23 and the wrist joint airbag 24 are as follows: Figure 2 and Figure 3 As shown, the inflation unit 4 includes a solenoid valve group 41, an air pressure sensor 42 and an air pump 43, and the air pressure sensor 42 is connected to the air pump 43 through an air pipe; the solenoid valve group 41 includes four two-way solenoid valves, and the four two-way solenoid valves are respectively connected to the supporting part 21 and the air pressure sensor 42, the shoulder joint airbag 22 and the air pressure sensor 42, the elbow joint airbag 23 and the air pressure sensor 42, and the wrist joint airbag 24 and the air pressure sensor 42 through air pipes; the independent inflation of the supporting part 21, the shoulder joint airbag 22, the elbow joint airbag 23 and the wrist joint airbag 24 is controlled by the switch of the solenoid valve group 41, so as to unlock the freedom of movement of the shoulder joint, elbow joint and wrist joint, as well as the freedom of the coordinated swing of the trunk, upper arm and forearm; the air pressure parameters are accurately fed back and the inflation pressure is controlled by the cooperation of the air pressure sensor 42 and the air pump 43, so as to accurately unlock the freedom of movement in different levels, and the recovery training of the freedom of movement of the corresponding level can be carried out according to the recovery degree of the arms and joints.

[0052] The solenoid valve group 41 , the air pressure sensor 42 and the air pump 43 are electrically connected to the control unit 5 respectively.

[0053] When in use, the inflation unit 4 is also provided with a confluence module 44, which is provided with four air outlets and one air inlet; the air outlet of the inflation pump 43 is connected with the air inlet of the air pressure sensor 42 through an air pipe, the air inlet of the air pressure sensor 42 is connected with the air inlet of the confluence module 44, the four air outlets of the confluence module 44 are respectively connected to the air inlets of four two-way solenoid valves, and the air outlets of the four two-way solenoid valves are respectively connected to the supporting part 21, the shoulder joint airbag 22, the elbow joint airbag 23 and the wrist joint airbag 24 through the air pipe; the two-way solenoid valve of the solenoid valve group 41 has an exhaust and pressure relief function, and exhausts air through the pressure relief port.

[0054] When the supporting part 21, shoulder joint airbag 22, elbow joint airbag 23 and wrist joint airbag 24 are inflated or exhausted independently, only a single two-way solenoid valve is opened. At this time, the airbags and the two-way solenoid valve air pressure sensors 42 corresponding to the air circuits are connected, and the air pressure of the connected airbags can be measured independently, and the air pressure of each independent airbag can be independently adjusted by venting the air through the two-way solenoid valve or inflating through the air pump 43.

[0055] Specifically, the method for controlling the degree of freedom and flexibility is to change the degree of expansion of the airbags by respectively adjusting the air pressure of the airbags of the supporting part 21, the shoulder joint airbags 22, the elbow joint airbags 23 and the wrist joint airbags 24. When the arm is swung and the joints are rotated, the resistance and physical constraints given to the arm and the joints by the airbags are changed. Therefore, by adjusting the air pressure of the airbags, the degree of freedom and flexibility of the arm and its joints can be unlocked and adjusted in stages, and the resistance given to the arm and its joints by the brace during abduction can be adjusted steplessly.

[0056] Firstly, the shoulder abduction brace of the present invention adopts an airbag structure, which can achieve comprehensive flexible support and protection for the armpit, arm and joints through the design of the segmented airbags, and designs a supporting and decompression force distribution structure to distribute the load of the supporting arm and joints to the waist-upper trunk segmented airbags in the vertical direction; this segmented airbag supporting structure can effectively fix the arm after surgery to prevent secondary injury, and at the same time, the air pressure can be adjusted at different rehabilitation stages to achieve precise control of the freedom of movement, thereby meeting the dual needs of postoperative fixation and rehabilitation training.

[0057] Secondly, the airbag is combined with the inflation unit 4, and is equipped with a touch screen 6 and a control unit 5 for human-computer interactive control, so that the user can flexibly adjust the air pressure parameters of each segmented airbag according to the recovery stage and the recovery feeling of his own arms and joints, so as to accurately adjust the freedom of movement of the shoulder joint, elbow joint and wrist joint, and control the swinging movement of the upper arm, forearm and arm; this function allows the user to keep the arm and joint in a stable posture during the postoperative fixation period, and gradually unlock the range of motion of the joints during the rehabilitation period, so as to carry out rehabilitation training step by step and improve the efficiency and effect of rehabilitation.

[0058] In addition, the brace distributes the load of the arms and joints between the shoulders and waist through the design of the waist belt 1 and the shoulder straps 92, thereby improving the stability of the arms. This supporting method reduces the pressure on the arms, especially the waist belt 1 fixed at the waist. The waist belt 1 itself has a wide size and a large fixed area. When part of the force of the arms and joints is distributed to the waist, the pressure per unit area of ​​the waist belt 1 is smaller, the pressure and load on the waist are reduced, the patient is more comfortable when wearing it, and it is more suitable for long-term use.

[0059] At the same time, the inflation unit 4 of the brace can accurately feedback and control the air pressure of each airbag through the independent electromagnetic valve group 41 and the air pressure sensor 42, so that the patient can perform more accurate rehabilitation training under the premise of ensuring safety.

[0060] Finally, the inflation unit 4 in this solution integrates the electromagnetic valve group 41, the air pressure sensor 42 and the inflation pump 43, ensuring the stability and accuracy of the air pressure regulation. By precisely regulating the air pressure, the freedom of movement of each joint can be unlocked in stages, gradually realizing the recovery training of the arm from fixed to linked swing and joint rotation; such a design can not only ensure the safety of the patient during the postoperative rehabilitation period, but also accelerate the rehabilitation process and make the functional recovery more scientific and reasonable.

[0061] In summary, the shoulder abduction brace of the present invention has many advantages such as postoperative fixation protection, air pressure regulation and control, segmented support and personalized adjustment, and has broad application potential in rehabilitation after shoulder and arm surgery.

[0073] A third embodiment of a novel shoulder abduction brace is as follows: Figure 1 As shown, the difference between this embodiment and the first embodiment is that a shoulder joint heating pad 71 is provided on the inner side of the shoulder joint auxiliary fixing cloth 28; an elbow joint heating pad 72 is provided on the inner side of the connection between the upper arm airbag 212 and the forearm airbag 213; a wrist joint heating pad 73 is provided on the inner side of the connection between the forearm airbag 213 and the hand airbag 214; the shoulder joint heating pad 71, the elbow joint heating pad 72 and the wrist joint heating pad 73 are electrically connected to the control unit 5 respectively.

[0074] During use, the heating temperature and time of the shoulder joint heating pad 71, the elbow joint heating pad 72 and the wrist joint heating pad 73 are controlled by the control unit 5. The heating pads of each joint can be used to preheat the shoulder joint, elbow joint and wrist joint respectively before unlocking the freedom of movement of the arms and joints, so that the arms and joints can be warmed up before the freedom of movement recovery training to avoid stiffness and injury.

[0075] A fourth embodiment of a novel shoulder abduction brace is as follows: Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the difference between this embodiment and the first embodiment is that the inner sides of the torso airbag 211, the upper arm airbag 212, the forearm airbag 213 and the hand airbag 214 are respectively provided with contoured three-dimensional ventilation pads 8.

[0076] When in use, the contoured three-dimensional ventilation pad 8 includes a torso contoured ventilation pad 81, an upper arm contoured ventilation pad 82, a forearm contoured ventilation pad 83 and a hand contoured ventilation pad 84, and are respectively attached to the inner side of the torso airbag 211, the inner side of the upper arm airbag 212, the inner side of the forearm airbag 213 and the inner side of the hand airbag 214 by Velcro.

[0077] The contoured three-dimensional ventilation pad 8 is made of flexible skin-friendly materials such as latex and TPE. Latex has a memory function and can fully fit the shape of the arm. When the airbag and the arm are training, it can cushion the relative displacement between the airbag and the arm, reducing the discomfort of the arm and joints. TPE is a flexible elastic material and also has contour-fitting properties. It can also fully deform to adapt to the shape of the airbag and the arm, and can also cushion the relative displacement between the airbag and the arm.

[0078] The overall shape of the contoured three-dimensional ventilation pad 8 is structurally obtained by collecting specific dimensions of the upper torso, upper arm, forearm and hand from many people of different heights and weights, and contoured ventilation pads of different sizes are designed through ergonomics. Similarly, the contoured airbags used in the airbag abduction brace 2 can also be collected in this way, so as to design contoured airbags of different sizes to suit the shapes of the waist, upper torso, armpit, arm and joints of users of different heights and weights.

[0079] The curved surface and side surfaces of the contoured three-dimensional ventilation pad 8 are designed with ventilation holes 85, so that when the contoured three-dimensional ventilation pad 8 is installed on the inner side of the airbag, the heat of the upper torso, upper arm, forearm and arm wrapped by the curved surface is transferred to the holes on the side surfaces through the holes on the curved surface, thereby forming a three-dimensional ventilation duct, which is convenient for users to dissipate heat when wearing the shoulder abduction brace of the present invention for a long time and relieve itching of the skin caused by long-term wearing.

[0080] The novel shoulder abduction brace of the present invention was tested by wearing. Figure 6 The results are shown below. 20 patients with shoulder joint diseases were selected for evaluation of brace wearing after surgery. The conditions were: the same patient, the same limb, wearing three braces in succession, and performing static fixation and active abduction movement tests. The collected data were statistically analyzed and averaged. The specific results are shown in the table below:

[0081]

[0082]

[0083] It can be seen that compared with the existing shoulder joint brace, the novel shoulder joint abduction brace of the present invention has the effects of wide abduction angle and stepless adjustment of abduction resistance, better adaptability and high patient satisfaction.

[0084] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described.
