Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation devices, and particularly relates to an abduction brace for shoulder. Background Art

[0002] An abduction brace for shoulder is a medical device used to support and stabilize the shoulder joint, mainly for the rehabilitation after shoulder joint surgery and the treatment of diseases such as shoulder joint dislocation and rotator cuff injury. Through the abduction brace for shoulder, the excessive movement of the shoulder joint can be restricted, unnecessary pressure or tension on the shoulder can be avoided, the stability of the shoulder joint can be improved, the pain of the patient can be relieved, muscle fatigue can be alleviated, and the rehabilitation of the shoulder joint can be promoted.

[0003] The structure of the existing abduction brace for shoulder is shown in Chinese Utility Model CN 212879723 U. It includes a backrest and a waistband for fixing the backrest. An arc-shaped groove for fitting with the human waist is formed through one end of the backrest. A support part for supporting the arm is arranged at the top of the backrest. The support part has an L-shaped opening and the opening faces away from the human body. A first fixing band and a second fixing band are fixedly arranged at the opening. The backrest can be fixed on the body through the waistband. Through the L-shaped opening, the arm can be supported. Then, by winding the first fixing band around the arm and bonding the second fixing band, the effective fixation of the arm can be achieved.

[0004] However, in actual use, the volume and self-weight of the backrest are relatively large, which is likely to affect the normal activities of the user. And affected by the L-shaped structure, under the downward pressure of the arm, the backrest has a tendency to turn outward to the arm side, which not only affects the stability of the support, but also makes the side of the backrest facing the waist unable to fit well with the waist side, bringing discomfort. This situation is particularly obvious when only the waistband is provided. After adding shoulder straps, this tendency can be slowed down and the stability of the backrest can be strengthened, but it also brings a great burden to the shoulder, and it is easy to cause shoulder pain after wearing for a long time.

The shape of the inner support surface 11 matches the shape of the side chest and side waist of the human body, and is used to support the chest and waist of the human body; the outer support surface 12 is arranged obliquely, and its shape matches the shape of the human arm, and is used to support the upper arm and forearm of the human body; the underarm support portion 13 is located at the upper intersection of the inner support surface 11 and the outer support surface 12, corresponding to the position of the human armpit.

[0030] The arm support sleeve 2 is fixedly connected to the outer support surface 12 and is used to support the forearm, and fix the forearm and even the entire arm on the outer support surface 12 of the abduction pillow 1. The waist belt 3 and the crossbody shoulder strap 4 are both fixedly connected to the abduction pillow 1, so that the user can wear the abduction pillow 1 and stably fix it on the waist side, and distribute the pressure brought by supporting the arm abduction to the waist and the other uninjured shoulder.

[0031] Due to the structural restrictions of the inner support surface 11, the outer support surface 12 and the underarm support part 13, the inner side of the abduction pillow 1 has a sufficient length in the vertical direction, and the bottom position of the inner support surface 11 is slightly lower than the bottom position of the outer support surface 12, which makes the cross-sectional shape of the abduction pillow 1 parallel to the coronal plane of the human body present a stable triangular shape, and is not easy to flip outward when supporting the arm abduction. It can not only ensure the fit between the inner support surface 11, the outer support surface 12 and the human chest, waist, and arm, and stably support the arm abduction, but also partially transfer the force resisting the abduction pillow 1 from eversion to between the upper arm and the chest, reducing the pressure of the crossbody shoulder strap 4 on the shoulder, improving stability and wearing comfort.

[0032] Specifically, an upper arm support area 121, a forearm support area 122 and an upper arm limiting part 123 are provided on the outer support surface 12. The upper arm support area 121 and the forearm support area 122 are smoothly connected, and after connection, they are generally in an L shape, which can respectively support the inner side of the upper arm and the inner side of the forearm, so that the arm maintains an abducted state.

The filling body filled inside the flexible outer cover can be made of elastic sponge to provide soft support, or an injection molded part can be selected to provide rigid support.

[0034] The above-mentioned arm support sleeve 2 includes a sleeve body 21 and a fixing band 22. The inner side of the sleeve body 21 encloses an accommodation space 211 for accommodating the arm, and a sleeve opening 212 for the arm to enter and exit the accommodation space 211 is formed on the sleeve body 21. The sleeve opening 212 is arranged along the length direction of the arm, and part of it is located on the front side of the upper arm and part of it is located on the upper side of the forearm, which is convenient for the arm to be inserted. The fixing band 22 is detachably connected to both sides of the sleeve opening 212, and then the sleeve opening 212 is opened and closed.

[0035] The fixing band 22 can be disconnected and connected by means of mother and son buckles, magic tapes, etc. Preferably, at least two fixing bands 22 are provided, and their positions correspond to the upper arm and forearm of the human body respectively. The sleeve opening 212 can be opened and closed at the upper arm and forearm at the same time, and then cooperate with the sleeve body 21 to fix the arm. After fixing, the position of the sleeve opening 212 corresponding to the elbow is in an open state, which has a certain air permeability. In addition, an elbow avoidance opening 213 is also opened at the bottom of the sleeve body 21. The elbow avoidance opening 213 connects the accommodation space 211 with the external environment, so that the elbow can leak out to avoid discomfort.

[0036] To enhance the supporting performance of the arm support sleeve 2, the brace further includes a strip-shaped forearm support plate 5 made of steel plate. The length direction of the forearm support plate 5 is consistent with the length direction of the forearm. The forearm support plate 5 can be arranged between the outer support surface 12 and the arm support sleeve 2 as shown in Figure 1 shown, or it can be as shown in Figure 6It is arranged inside the arm support sleeve 2, that is, inside the above-mentioned accommodation space 211. Preferably, the forearm support plate 5 can also be wrapped between the layers of the arm support sleeve 2, which not only ensures aesthetics but also can reduce the foreign body sensation and discomfort in the forearm part during wearing. The forearm support plate 5 is fixedly connected to the abduction pillow 1, and the position of the plate surface of the forearm support plate 5 corresponds to the inner side of the human forearm, which can significantly improve the support performance of the arm support sleeve 2 without occupying too much space and being unobtrusive, combining aesthetics and practicality.

[0037] This brace is worn and fixed to the abduction pillow 1 through the waistband 3 and the cross-body shoulder strap 4. To adapt to different body types and ensure the fitting degree of the abduction pillow 1, the waistband 3 and the cross-body shoulder strap 4 are adjusted, fixed and made convenient to wear by means of Velcro, adjustment buckles, etc.

[0038] The brace is also provided with a front chest connecting piece 6 and a back connecting piece 7. The front chest connecting piece 6 and the back connecting piece 7 are arranged opposite to each other, and one side edge of each of them is respectively connected to the front and back side edges of the abduction pillow 1. The two ends of the cross-body shoulder strap 4 are respectively connected to the upper part of the front chest connecting piece 6 and the upper part of the back connecting piece 7; the two ends of the waistband 3 are respectively connected to the lower part of the front chest connecting piece 6 and the lower part of the back connecting piece 7. Through the front chest connecting piece 6 and the back connecting piece 7, not only the connection between the waistband 3, the cross-body shoulder strap 4 and the abduction pillow 1 is made more stable, but also the pulling force received by the abduction pillow 1 is made uniform and not easily damaged. At least a part of the waistband 3, the cross-body shoulder strap 4, the front chest connecting piece 6 and the back connecting piece 7 is made of mesh cloth to ensure breathability during wearing and improve wearing comfort.

[0039] In addition, since some users have a relatively small body size and the width of the cross-body shoulder strap 4 is correspondingly narrow, a widened shoulder pad 41 is also provided in the brace. The widened shoulder pad 41 is slidably sleeved outside the cross-body shoulder strap 4 along the length direction of the cross-body shoulder strap 4, which can significantly reduce the shoulder pressure during wearing.

[0040] In summary, it can be seen that this shoulder abduction brace has good stability during use, better wearing comfort, a small volume, is convenient for the user to move, and has good aesthetics.
