Description

Technical Field

[0001] The present invention relates to the technical field of shoulder braces, and particularly to a rehabilitation brace for preventing shoulder subluxation. Background Art

[0002] Shoulder subluxation is one of the common shoulder injuries, especially common among athletes, the elderly, and hemiplegic patients. Clinically, generally by wearing a brace, using the "lifting and supporting" function of the brace to prevent shoulder subluxation.

[0003] Common braces for preventing shoulder subluxation generally have two forms: the arm support form (a bracket supporting the forearm) and the lifting form (by pulling the strap fixed on the upper arm). Among them, for the arm support form, although it solves the problem of shoulder subluxation, it also brings other problems: the range of motion of the shoulder joint is limited, which will induce muscle tension (upper limb flexor spasm pattern), and then lead to shoulder pain, and it is also not conducive to the rehabilitation of the shoulder joint. Therefore, the brace in the arm support form is generally not recommended.

[0004] The brace in the lifting form pulls the strap fixed on the upper arm through the shoulder pad fixed on the shoulder joint. Although it can achieve a better anti-dislocation effect, to effectively lift the upper arm, it is necessary to tie the strap tightly on the upper arm, but tying it too tightly will cause discomfort to the patient. Especially, the upper limb on the hemiplegic side is prone to edema, and the tightly tied strap will affect venous return and further aggravate the swelling.

[0005] Based on this, we propose a rehabilitation brace for preventing shoulder subluxation. Summary of the Invention

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-6 , a rehabilitation brace for preventing shoulder joint subluxation, including a chest strap 1 fixed at the chest position of the patient. As Figure 1 shown, shoulder straps 2 are also provided on both sides of the top of the chest strap 1 for further fixing the position of the chest strap 1. The chest strap 1 and the shoulder straps 2 can specifically use straps in the form of Velcro in the prior art, which will not be elaborated in this embodiment.

[0023] As Figure 1 shown, an arm strap 3 is tied and fixed to the upper arm of the patient. The arm strap 3 can also directly use a strap in the form of Velcro in the prior art, and the tying method thereof is not specifically limited in this embodiment.

[0024] The main improvement of the present invention lies in the connection between the chest strap 1 and the arm strap 3. Specifically, as Figure 1 shown, a vertical plate 4 and an inclined plate 5 connected by an arc-shaped airbag 6 at the top are respectively installed on the adjacent sides of the chest strap 1 and the arm strap 3. The arc-shaped airbag 6 is preset to be U-shaped, and as it is inflated, its shape can gradually tend to be horizontal (refer to Figure 6 ).

[0025] Thus, in actual use, by making the inclined plate 5 in an inclined state, the upper arm can be supported to abduct and lifted, playing a role in preventing shoulder joint subluxation. Compared with the brace in the form of supporting the arm, it does not limit the range of motion of the shoulder joint. Compared with the brace in the form of lifting, since it does not lift along the direction of the arm but supports obliquely, the fastening requirement for the arm strap 3 is also lower. Even if the arm strap 3 is tied loosely, the upper arm can still be lifted.

[0026] In the present invention, the inclined plate 5 is a plate with a certain flexibility, which is tied and fixed to the upper arm by the arm strap 3 and adheres to the skin. That is, the inclined plate 5 is tied and fixed at the position by the arm strap 3. Further, the inclined plate 5 and the inner wall of the arm strap 3 can be adhered by Velcro, so as to further improve the connection effect; In this way, even if the arm strap 3 is tied loosely, relying on the inclined plate 5, the upper arm can still be supported to abduct and lifted. Since the arc-shaped airbag 6 has flexibility, the patient's arm can also move freely within a certain range without affecting the exercise of the shoulder joint.

[0027] In the present invention, in order to further improve the support for the upper arm, the vertical plate 4, the arc-shaped airbag 6 and the inclined plate 5 can still move up and down. Thus, by controlling the vertical plate 4 to move slightly upward, the upper arm can be further lifted to avoid shoulder joint subluxation; Specifically, as Figure 2As shown in the figure, a fixing plate 10 is fixedly installed on one side of the chest strap 1 close to the armband 3. A threaded rod 11 is rotatably installed inside the fixing plate 10. One end of the threaded rod 11 is rotatably installed on the inner wall of the fixing plate 10, and the other end extends to the outside of the fixing plate 10 and is fixedly connected to an adjusting knob 13. In addition, a nut 12 is screwed on the outer wall of the threaded rod 11, and the vertical plate 4 is fixedly installed on the nut 12; Therefore, when it is necessary to adjust the position of the vertical plate 4, the threaded rod 11 can be rotated by the adjusting knob 13 to move the nut 12 up and down. The up and down movement of the nut 12 can drive the vertical plate 4 to move up and down to finely adjust the position.

[0028] In the present invention, when the arc-shaped airbag 6 is inflated, its shape can gradually tend to be horizontal, thereby controlling the degree of abduction of the upper arm; In order to facilitate the inflation of the arc-shaped airbag 6, a manual inflation mechanism is also provided in this embodiment. Specifically, as Figure 1 、 Figure 4 and Figure 5 shown, the arc-shaped airbag 6 is connected to the airbag ball 8 through an inflation tube 7. A one-way intake valve is provided on the airbag ball 8, and a one-way exhaust valve is provided on the inflation tube 7. Therefore, by squeezing the airbag ball 8 back and forth, the arc-shaped airbag 6 can be inflated.

[0029] In addition, a deflation nozzle 9 is also provided on the inflation tube 7 for discharging gas. Specifically, reference can be made to Figure 5 , the deflation nozzle 9 is specifically a deflation cylinder 901, the inner cavity 902 of which is connected to the inflation tube 7, and the connection position is above the one-way exhaust valve; A conical slope 903 is formed on the inner wall of the inner cavity 902. A conical plug 904 is movably blocked on the conical slope 903. A lead screw 906 is rotatably installed on the conical plug 904. The other end of the lead screw 906 is connected to a knob 907 and is screwed into a nut 905. The nut 905 is fixedly installed at the end of the deflation cylinder 901. In addition, an exhaust hole 908 is also opened at the end of the deflation cylinder 901; Therefore, when it is necessary to discharge gas, rotate the knob 907 to make the conical plug 904 disengage from the conical slope 903. On the contrary, keeping the conical plug 904 close to the conical slope 903 can maintain the seal.

[0030] Embodiment Two: Please refer to Figures 1-3 , on the basis of Embodiment One, in this embodiment, a small arm support pad 15 is also connected to the bottom of the vertical plate 4 through a suspension rope 14 for suspending the small arm.

[0031] As Figure 3As shown in the figure, the inside of the vertical plate 4 is separated by a partition plate 19 to form an upper chamber and a lower chamber. Inside the lower chamber, a piston 16 is supported by a support spring 18. A bottom rod 17 is fixedly installed at the bottom of the piston 16. The bottom end of the bottom rod 17 extends to the outside of the vertical plate 4 and is fixedly connected to the suspension rope 14. Inside the upper chamber, a movable plug 21 is arranged to move up and down, and the top of the movable plug 21 is connected to the arc-shaped airbag 6 through a jacking rod 22. In addition, the bottom of the lower chamber is communicated with the bottom of the upper chamber through a communication pipe 20 buried in the wall of the vertical plate 4. When the forearm is suspended by the forearm support pad 15, under the action of the gravity of the forearm itself, the piston 16 is pulled down by the suspension rope 14 and the bottom rod 17, and the support spring 18 is compressed. When the piston 16 moves down, the air in the lower chamber is filled into the upper chamber through the communication pipe 20, thereby pushing the movable plug 21 to move up. When the movable plug 21 moves up, the arc-shaped airbag 6 and the inclined plate 5 can be driven to move up through the jacking rod 22 to further support the upper arm and avoid shoulder subluxation, without having to turn the adjustment knob 13 anymore.

[0032] In clinical applications, if the patient suspends the forearm, the inclined plate 5 will automatically move up to further support the upper arm. If the patient does not suspend the forearm, the inclined plate 5 can be controlled to move up through the adjustment knob 13.

[0033] In the present invention, the penetration part of the bottom rod 17 on the vertical plate 4 is sealed by a seal to ensure the sealing effect.

[0034] Embodiment 3: Please refer to Figure 2 and Figure 7 Based on Embodiment 1 or Embodiment 2, in this embodiment, an upper expansion tube 23 and a lower expansion tube 25 are respectively buried at the upper and lower ends of the inclined plate 5. As Figure 2 shown, the upper expansion tube 23 is communicated with the bottom of the upper chamber through an air pipe 1, and the lower expansion tube 25 is communicated with the top of the lower chamber through an air pipe 2. When the piston 16 is at a high position, the lower expansion tube 25 bulges, and the upper expansion tube 23 is in its original state. On the contrary, when the piston 16 is at a low position, the lower expansion tube 25 is in its original state, and the upper expansion tube 23 bulges; Specifically, when the piston 16 moves down, the gas in the lower expansion tube 25 will enter the lower chamber through the air pipe 2, and the lower expansion tube 25 gradually tends to its original state. As the piston 16 gradually moves down and the movable plug 21 gradually moves up, when the movable plug 21 moves to the end position and cannot move up anymore (in this embodiment, the length of the lower chamber is greater than the length of the upper chamber), the gas in the upper chamber will enter the upper expansion tube 23 through the air pipe 1, causing the upper expansion tube 23 to bulge; The purpose of the upper expansion tube 23 or the lower expansion tube 25 bulging is to tighten the connection of the armband 3. Through the variable and alternating inflation of the two, the main connection stress points of the armband 3 on the upper arm can be changed to prevent patient discomfort or limb edema. Specifically, when the lower arm is not suspended, the lower part of the armband 3 is tightened by the lower expansion tube 25; when the lower arm is suspended, the upper part of the armband 3 is tightened by the upper expansion tube 23.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
