[0002] After the patient completes the shoulder joint surgery, the posterior arm of the upper limb needs to maintain a suitable abduction position to protect the repaired tissue and promote healing. Therefore, a shoulder fixation brace is needed to fix and correct shoulder and hand injuries.

[0003] The Chinese utility model patent with the authorization announcement number CN216908282U discloses a shoulder joint brace, which includes a brace body, a shoulder strap and a waist belt. The two ends of the shoulder strap are respectively fixed obliquely on both sides of the brace body, and are used to rest on the patient's unoperated shoulders. The two ends of the waist belt are fixed horizontally on both sides of the brace body. The brace body is provided with a receiving area for placing the arm, and an armband for fixing the arm is installed at the receiving area.

[0004] Regarding the above-mentioned related technologies, when using the above-mentioned shoulder joint brace, since the patient's arm remains in a fixed position for a long time, it will restrict muscle activity, cause joint stiffness, and affect rehabilitation efficiency. Utility Model Content

[0005] In order to relieve the joint stiffness caused by patients wearing shoulder joint braces for a long time, the utility model provides an angle-adjustable shoulder joint abduction brace.

[0006] The utility model provides an adjustable angle shoulder abduction brace adopts the following technical solution:

[0007] An adjustable angle shoulder abduction brace comprises a brace body, wherein the brace body is provided with shoulder straps and a waist belt for wearing and fixing, and further comprises an elastic deformable part arranged on the brace body and an inflatable part for inputting gas into the elastic deformable part, wherein the elastic deformable part has a accommodating chamber for accommodating gas, and the elastic deformable part is provided with a deflation part for releasing the internal gas; an arm to be rehabilitated is placed on the elastic deformable part, and when the inflatable part is used, the elastic deformable part expands and deforms and drives the arm to be abducted, and when the deflation part is used, the gas in the accommodating chamber flows out, so that the elastic deformable part is compressed and reset and drives the arm to be adducted.

[0008] By adopting the above technical solution, the arm of the patient to be rehabilitated is fixed on the elastic deformation member. When joint stiffness occurs after wearing for a certain period of time, the inflating member conveys gas to the accommodating cavity to realize the expansion of the elastic deformation member. The expansion and deformation of the elastic deformation member drive the arm to abduct, and the abduction angle is adjusted by the gas filled. Then, the gas in the accommodating chamber is released through the deflating member, so that the elastic deformation member compresses and resets. The compression and deformation of the elastic deformation member drive the arm to adduct. The above structural arrangement enables the arm of the patient to perform abduction and adduction movements when wearing the shoulder joint brace, which helps to improve the rehabilitation of the shoulder.

[0009] Optionally, the elastic deformation member includes a fixed portion and a deformed portion. The fixed portion and the deformed portion are fixedly connected, and the fixed portion is closer to the human body side relative to the deformed portion. The deformed portion is provided with an armband for fixing the arm, and the accommodating cavity is located within the deformed portion.

[0010] By adopting the above technical solution, the elastic deformation member includes a fixed portion and a deformed portion, and the accommodating cavity is within the deformed portion. When the elastic deformation member is inflated, the deformed portion expands and deforms, and the fixed portion does not deform, enabling the deformed portion to expand with the fixed portion as the axis, facilitating the abduction of the arm.

[0011] Optionally, the side wall where the deformed portion and the fixed portion are in contact is a fixed arc surface, and the side wall of the deformed portion is provided with pleated wrinkles, which enable the deformed portion to expand with the center of the fixed arc surface as the axis.

[0012] By adopting the above technical solution, through the setting of the pleated wrinkles, the deformed portion can expand or retract in a fan shape with the center of the fixed arc surface as the axis when deforming, restricting the expansion direction of the deformed portion and improving the user experience.

[0013] Optionally, an arc-shaped handle is provided at the top of the fixed portion.

[0014] By adopting the above technical solution, with the setting of the arc-shaped handle, the user can remove the elastic deformation member from the brace body by holding the arc-shaped handle, further improving the disassembly efficiency of the elastic deformation member.

[0015] Optionally, the brace body is provided with an installation groove for arranging the elastic deformation member. A first adhesive sticker is provided on the side of the elastic deformation member close to the human body and on the bottom wall facing the installation groove, and a second adhesive sticker for cooperating with the first adhesive sticker for bonding is provided on the inner wall of the installation groove.

[0016] By adopting the above technical solution, the fixing method of the elastic deformation member and the brace body is disclosed. The elastic deformation member is positioned and placed in the installation groove, and then fixed through the cooperation of the first adhesive sticker and the second adhesive sticker. The fixing method using the adhesive sticker facilitates the disassembly and assembly of the elastic deformation member.

[0017] Optionally, a positioning groove for placing the arm is provided on the deformable part, and the arm bands are arranged at intervals along the extending direction of the positioning groove.

[0018] By adopting the above technical solution, the arrangement of the positioning groove can limit and place the patient's arm in the positioning groove and fix it with the arm band, which can reduce the probability of the arm and the deformable part slipping when the arm abducts and adducts.

[0019] Optionally, the inflatable member is an elastic ball, and a connecting member connecting the elastic ball and the deformable part is provided on the brace body. The connecting member includes a first air nozzle provided on the elastic ball, a second air nozzle provided on the elastic deformable member, and a connecting pipe connecting the two air nozzles.

[0020] By adopting the above technical solution, another form of the inflatable member is disclosed. The elastic ball is communicated with the deformable part through the connecting member. When the deformable part needs to be inflated, the user squeezes the elastic ball, and the gas in the elastic ball is input into the deformable part along the connecting member, and repeated squeezing of the elastic ball realizes inflation.

[0021] Optionally, the elastic ball is arranged at one end of the elastic deformable member and close to the palm side.

[0022] By adopting the above technical solution, the elastic ball is placed at the end of the elastic deformable member, so that the patient can perform squeezing operations through the arm fixed on the deformable part, and while the arm abducts and adducts, the auxiliary exercise effect is realized, promoting blood circulation.

[0023] Optionally, the inflatable member is a pump, and a communication hole communicating with the installation groove and for installing the pump is provided on the side wall of the brace body. A flexible air pipe communicating with the deformable part is provided at the end of the pump.

Detailed Description of the Embodiments

[0034] The following is a further detailed description of the present utility model in conjunction with the attached Figures 1-4 drawings.

[0035] An embodiment of the present utility model discloses an adjustable-angle shoulder abduction brace.

[0036] Embodiment 1

[0037] Referring to Figure 1 , an adjustable-angle shoulder abduction brace includes a brace body 1, and a shoulder strap 2, a waistband 3, an elastic deformation component 4, and an inflatable component 5 are arranged on the brace body 1. The brace body 1 is in the shape of a rectangular block, and the side thereof close to the human body has a concave arc surface for improving the comfort of the abduction brace. The two ends of the shoulder strap 2 are respectively and obliquely fixed on both sides of the brace body 1 for fixing with the shoulders of the human body; the two ends of the waistband 3 are respectively and horizontally fixed on both sides of the brace body 1 for fixing with the waist of the human body. It is defined that the side of the brace body 1 facing the chest of the human body is the front side, and the side facing the back of the human body is the back side.

[0038] Referring to Figure 2 and Figure 3, the top of the brace body 1 has an installation groove 11 for positioning and placing the elastic deformation member 4, and the size of the installation groove 11 is larger than that of the elastic deformation member 4. The elastic deformation member 4 includes a fixing portion 41 and a deformation portion 42. The fixing portion 41 is a plate body with an L-shaped cross-section, and the vertical plate thereof is attached to the side of the installation groove 11 close to the human body. The deformation portion 42 is made of an elastic material and can undergo expansion deformation. The fixing portion 41 is made of a rigid material, and when the deformation portion 42 deforms, the fixing portion 41 does not deform.

[0039] Specifically, the deformation portion 42 has a receiving chamber for accommodating gas. The gas is conveyed to the receiving chamber of the deformation portion 42 through an inflating member 5, driving the deformation portion 42 to expand and deform. A plurality of arm bands 43 for fixing the arm are fixed to the top of the deformation portion 42. The patient can convey gas to the receiving chamber through the inflating member 5, so that the deformation of the deformation portion 42 drives the arm to perform an abduction movement.

[0040] At the same time, in order to realize the adduction and reduction of the arm, a deflating member 6 for deflating is installed on the deformation portion 42. In this embodiment, the deflating member 6 is a deflating nozzle in the prior art, and the communication and sealing between the receiving chamber and the outside are realized by pulling up and buckling. When it is necessary to restore the deformation portion 42 to the initial state, only need to open the deflating nozzle, and the gas in the receiving chamber can be automatically discharged under the gravity of the arm, and the deformation portion 42 compresses and resets, driving the patient's arm to perform an adduction movement.

[0041] Refer to Figure 2 and Figure 3 , the side wall and the bottom of the fixing portion 41 are both installed with first adhesive stickers 411. The brace body 1 is installed with second adhesive stickers 12 on the inner wall of the installation groove 11 that cooperate with the first adhesive stickers 411. Among them, an arc-shaped handle 412 is also fixedly installed on the top of the fixing portion 41, so as to facilitate the installer to take out the elastic deformation member 4 as a whole from the installation groove 11 and improve the disassembly efficiency. In this embodiment, the adhesive sticker is a magic tape.

[0042] In order to limit the expansion direction of the deformation portion 42, the side wall where the deformation portion 42 and the fixing portion 41 are fixedly connected is a fixed arc surface 413, and the radian center of the fixed arc surface 413 is adapted to the rotation center of the shoulder joint of the arm. The deformation portion 42 is provided with pleated wrinkles on the side walls except the fixed arc surface 413. The pleated wrinkles and the deformation portion 42 are integrally formed, and the pleated wrinkles are arranged at equal intervals along the extending direction of the installation groove 11. Through the arrangement of the pleated wrinkles, when the deformation portion 42 expands or compresses, the whole deformation portion 42 can expand in a fan shape along the center of the fixed arc surface 413, ensuring that the arm can perform abduction and adduction within a certain angle range.

[0043] The top of the deformation part 42 has a positioning groove 421 for horizontally arranging the arm, which is used to reduce the probability of the arm sliding when the deformation part 42 deforms. The positioning groove 421 is a strip-shaped groove, and one end of it penetrates through the side wall of the deformation part 42. The front side of the brace body 1 has an extension groove 13 corresponding to the positioning groove 421.

[0044] The inflatable member 5 is arranged on the front side of the brace body 1, that is, on the palm side. In this embodiment, the inflatable member 5 is an elastic ball 51 with an internal chamber. The inflatable member 5 and the deformation part 42 are communicated through a connecting member 7. The connecting member 7 includes a first air nozzle 71 installed on the elastic ball 51, a second air nozzle 72 installed on the deformation part 42, and a connecting pipe 73 connecting the two air nozzles. The connecting pipe 73 is a hose with a telescopic function. The two air nozzles function as one-way valves. When the patient uses the hand fixed on the deformation part 42 to squeeze the elastic ball 51, the gas in the elastic ball 51 can be input into the accommodating chamber through the connecting pipe 73. After relaxation, the elastic ball 51 returns to its deformed state, and by repeating the squeezing, the deformation part 42 expands and deforms.

[0045] The implementation principle of the adjustable-angle shoulder abduction brace in the embodiment of the present utility model is as follows: The patient realizes the expansion and deformation of the deformation part 42 by repeatedly squeezing the elastic ball 51, and the deformation of the deformation part 42 drives the arm to perform abduction movement; after the deformation part 42 expands to a certain angle, the air release nozzle is opened, so that the deformation part 42 starts to compress and deform and gradually returns to the initial state, and the compression of the deformation part 42 drives the arm to perform adduction movement. While the patient uses the elastic ball 51 to exercise the muscles, the overall abduction of the arm is realized at the same time, alleviating the stiffness caused by the joint remaining stationary for a long time.

[0046] Embodiment 2:

[0047] Compared with Embodiment 1, in this embodiment, except that the structure of the inflatable member 5 is different, the rest of the structures are the same as those of the shoulder abduction brace in Embodiment 1.

[0048] Refer to Figure 4 , in this embodiment, the inflatable member 5 is a pump 52, and the structure of the pump 52 is the same as that in the prior art. The front side of the brace body 1 has a communication hole 14 communicating with the installation groove 11. The barrel of the pump 52 is limited and inserted into the communication hole 14. The side wall of the deformation part 42 has an air hole 422 corresponding to the communication hole 14 and communicating with the accommodating chamber. The air hole 422 and the air outlet of the pump 52 are connected through an elastic hose 74. When the patient wears the shoulder abduction brace for a long time and the joint becomes stiff, the piston rod of the pump 52 can be repeatedly pulled by the other hand to realize the expansion and deformation of the deformation part 42. The air release method is the same as that in Embodiment 1.

[0049] The above are all the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present utility model shall be covered within the protection scope of the present utility model.
