Description

Technical Field

[0001] The present invention relates to the technical field of shoulder joint rehabilitation, and specifically to a multi-dimensional dynamic balance stabilizer for the shoulder joint. Background Art

[0002] The shoulder joint is one of the most flexible but also the most unstable joints in the human body. Its complex anatomical structure and extensive range of motion make it vulnerable to injury. Shoulder joint injuries are common in sports injuries, overuse, trauma, or degenerative diseases (such as frozen shoulder, rotator cuff injury, etc.). Traditional shoulder joint support devices usually adopt a fixed or single-dimensional support design. Although they can provide a certain degree of stability, there are the following problems in actual use. Traditional support devices often restrict the movement of the shoulder joint through rigid fixation. Although they can reduce abnormal displacement, they also limit the normal range of motion of the shoulder joint, affecting the daily function recovery and motor ability of users. The movement of the shoulder joint is multi-dimensional, including complex movements such as forward flexion, backward extension, abduction, adduction, internal rotation, and external rotation. In addition, it is unable to dynamically adjust the support force and direction according to the actual movement trajectory and force condition of the shoulder joint, resulting in poor support effect or discomfort during wearing.

[0003] According to the authorized announcement CN 212592982 U, an auxiliary device for shoulder joint rehabilitation is disclosed, which includes a shoulder guard plate, an upper arm auxiliary mechanism, an upper arm forward and backward swing movement mechanism, and an upper arm left and right extension mechanism. The shoulder guard plate is buckled on the shoulder of the user. The upper arm auxiliary mechanism includes two upper arm auxiliary rods, which are connected by a fixed sleeve. The upper arm forward and backward swing movement mechanism includes a bionic deltoid muscle A, a gear motor, and a gear. The upper arm left and right extension mechanism includes a bionic deltoid muscle B, a wire winding motor, and a pulley. The gear motor drives the gear to rotate, driving the bionic deltoid muscle A to slide back and forth, thereby realizing the forward and backward swing of the upper arm; the wire winding motor drives the wire winding wheel to rotate, and the wire winding drives the bionic deltoid muscle B to move left and right, thereby realizing the left and right extension movement of the upper arm.

[0004] The above-mentioned patent has the problem of restricting the movement of the shoulder joint during use. It needs to be driven by a wire winding motor, and the user cannot freely use the arm and shoulder joint, and the comfort of wearing cannot be guaranteed, resulting in discomfort for the user during wearing and use. Therefore, a multi-dimensional dynamic balance stabilizer for the shoulder joint is now needed. Summary of the Invention

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] The present invention provides: a shoulder joint multi-dimensional dynamic balance stabilizer, as Figures 1-6 shown, including a shoulder strap 1, a positioning belt 2 is sewn in the middle of the upper surface of the shoulder strap 1, a damping rotating joint is rotatably installed on one side of the positioning belt 2, and an elastic support plate 6 is adhered to the outside of the positioning belt 2 on the upper part of the shoulder strap 1. The shoulder strap 1 serves as the basic support part, and the positioning belt 2 is sewn in the middle of its upper surface. This design not only enhances the stability of the shoulder strap but also provides additional flexibility through the damping rotating joint on the positioning belt 2. The introduction of the damping rotating joint enables the shoulder strap 1 to better adapt to the shoulder curve of the user and reduce the discomfort caused by long-term wearing;

[0033] A restraint component for limiting the arm is rotatably installed at the end of the damping rotating joint. The installed restraint component can be well connected to the patient's arm and better cooperate with the shoulder strap 1 to limit the whole device.

[0034] At both upper ends of the shoulder strap 1, a set of first restraint straps 13 are respectively rotatably installed. At both lower ends of the shoulder strap 1, a set of force-bearing straps 16 are respectively rotatably installed. In the middle of the two sets of force-bearing straps 16, an elastic fitting cloth strap 17 for cooperating with the two sets of first restraint straps 13 is sewn. The two sets of force-bearing straps 16 limit the elastic fitting cloth strap 17, and the elastic fitting cloth strap 17 can fit the wearer's body. The installed first restraint straps 13 are pulled from the front and back of the wearer and pasted with the elastic fitting cloth strap 17 to complete the limitation, improving the firmness of the device when worn.

[0035] An auxiliary support component is movably inserted and installed outside the elastic fitting cloth strap 17. The top end of the auxiliary support component is movably inserted and installed with the restraint component. The auxiliary support component can be freely selected for installation. Its main purpose of use is to assist the cooperator with a shoulder joint injury to move the shoulder.

[0036] The damping rotating joint includes a connecting belt 8 rotatably connected to the positioning belt 2 and a bent rod 11 rotatably installed on the upper surface of the connecting belt 8. The installed bent rod 11 can ensure the flexibility of the device during use.

[0037] The restraint component includes an arm band 25 rotatably connected to the connecting belt 8. A flexible fitting cloth strap 31 is movably installed at the lower part of the arm band 25 through a second restraint strap 30. The arm band 25 and the flexible fitting cloth strap 31 can better fit the wearer's arm, improving the stability and comfort of the device during use.

[0038] The auxiliary support component includes an elastically supported rod 23 installed rotatably. The installed elastically supported rod 23 plays a certain supporting role, and due to the rotatability at both ends of the elastically supported rod 23, it makes it more convenient for the wearer to move the shoulder joint.

[0039] Preferably, a heater 3 is installed at the center of the positioning belt 2, a protective cotton 5 is sewn on the inner side of the shoulder strap 1 corresponding to the position of the heater 3, a group of pressure-sharing force plates 7 are respectively installed at both ends of the elastic support plate 6, and each group of pressure-sharing force plates 7 is adhesively installed on the surface of the shoulder strap 1. The arc-shaped bottom of the elastic support plate 6 does not contact the surface of the heater 3. The elastic support plate 6 is located above the shoulder strap 1, and its arc-shaped design avoids direct contact with the heater 3, ensuring the safe use of the heater. The addition of the pressure-sharing force plates 7 further disperses the pressure on the shoulders and improves the wearing comfort. In addition, the heater 3 is arranged to heat the shoulder joint when cooperating with the device, which has the effect of assisting blood circulation. In addition, the protective cotton 5 is arranged to protect the shoulders and improve the wearing comfort. The elastic support plate 6 positions the shoulder strap 1. Since the elastic support plate 6 itself is an arched structure, it can adjust and adapt to users of different volumes according to its own elasticity when the shoulder strap 1 is worn, and has good adaptability.

[0040] Further, a first mounting plate 9 is sewn on the outer surface of the connecting belt 8, a positioning seat 10 is installed on the upper surface of the first mounting plate 9, and one end of the bent rod 11 rotates inside the positioning seat 10. The connecting belt 8 can ensure the flexibility of the use of the arm band 25, and at the same time limit the first mounting plate 9, so that one end of the bent rod 11 can be stably limited.

[0041] Furthermore, two groups of first restraint bands 13 are movably riveted to the surface of the shoulder strap 1 through a group of first triangular connecting bands 12. A magic male hook 14 is sewn on one side of the tail of each group of first restraint bands 13. The first restraint bands 13 are connected to the shoulder strap 1 through the first triangular connecting bands 12, which can ensure the rotational flexibility of the first restraint bands 13. In addition, the sewn magic male hook 14 cooperates with the magic female hook 18 on the outer side of the elastic fitting cloth belt 17, which can ensure the stable fitting of the shoulder strap 1 to the wearer's shoulder.

[0042] It should be noted that two groups of stress bands 16 are respectively movably riveted to the lower part of the shoulder strap 1 through a group of second triangular connecting bands 15. Two groups of magic female hooks 18 are symmetrically embedded and sewn on the outer side of the elastic fitting cloth belt 17. A second mounting plate 19 is adhesively attached to the middle of the outer surface of the elastic fitting cloth belt 17. The elastic fitting cloth belt 17 can better fit the wearer's body. The first restraint bands 13 and the stress bands 16 are connected to the shoulder strap 1 through the first triangular connecting bands 12 and the second triangular connecting bands 15. This design not only enhances the overall stability, but also realizes quick wearing and adjustment through the cooperation of the magic male hook 14 and the magic female hook 18.

[0043] When wearing, it only needs to ensure that the shoulder strap 1 is fitted to the shoulder. The set elastic fitting cloth belt 17 will naturally hang on one side of the wearer's body along with the stress band 16. After that, only need to pull the first restraint band 13 on one side, so that the magic male hook 14 at the end of the first restraint band 13 fits with the magic female hook 18 on the outer side of the elastic fitting cloth belt 17, and it is very convenient to wear.

[0044] Specifically, a first limiting socket 20 is fixedly installed on the outer surface of the second mounting plate 19, and a group of mounting seats 22 are respectively provided at both ends of the elastic support rod 23, and a first positioning plug plate 21 is fixedly installed on the outer end of one group of mounting seats 22, and a second positioning plug plate 24 is fixedly installed on the outer end of the other group of mounting seats 22. The second mounting plate 19 outside the elastically fitted cloth tape 17 not only enhances the supporting force of the cloth tape, but also realizes the overall coordinated operation through the connection between the first limiting socket 20 and the auxiliary support assembly.

[0045] In addition, a positioning shaft 26 is installed at one end of the arm strap 25, and the positioning shaft 26 passes through the inside of the connecting belt 8. A limiting plate 27 is extended to both sides at the other end of the arm strap 25. A fitting plate 28 is installed in the middle of the upper surface of the arm strap 25, and a connecting plate 29 is fixedly installed on the top of the fitting plate 28. Another set of positioning seats 10 are installed on the surface of the connecting plate 29, and the end of the bent support rod 11 is rotatably installed inside the positioning seat 10 installed on the outer surface of the connecting plate 29. The restraint assembly includes the arm strap 25 and the second restraint strap 30. This design not only provides effective limitation for the arm, but also increases the contact area with the skin through the flexible fitting cloth belt 31, thereby improving the wearing comfort and stability.

[0046] Furthermore, a group of second restraints 30 are passed through the inside of the limiting plates 27 on both sides of the arm strap 25, and a group of flexible fitting cloth belts 31 are movably passed through the lower part of the arm strap 25 through the second restraints 30. The two ends of the second restraints 30 are fastened and connected by buckles 32. The buckles 32 can challenge the use length of the flexible fitting cloth belts 31, thereby greatly improving the overall stability and comfort of the device.

[0047] Specifically, a protective seat 33 is fixedly installed at the lower part of the flexible fitting cloth belt 31, the second restraining belt 30 passes through the channel inside the protective seat 33, and a second limiting socket 34 is fixedly installed at the bottom of the protective seat 33. The protective seat 33 at the lower part of the flexible fitting cloth belt 31 not only enhances the supporting force for the arm, but also realizes the overall coordinated operation through the connection with the auxiliary supporting component through the second limiting socket 34.

[0048] It is worth mentioning that the first limit socket 20 has a socket upward, and the second limit socket 34 has a socket on one side. The first positioning plate 21 is vertically inserted into the first limit socket 20, and the second positioning plate 24 is horizontally inserted into the second limit socket 34. Through horizontal and vertical insertion, the elastic support rod 23 as a whole is less likely to fall off during use, further improving the safety of the device.
