Description

Technical Field

[0001] This utility model relates to the technical field of medical supplies, and more specifically, to a bandage for rotator cuff injuries. Background Technology

[0002] Rotator cuff injuries refer to injuries to the tendons of the muscles covering the front, top, and back of the shoulder joint, such as the subscapularis, supraspinatus, infraspinatus, and teres minor. The majority of these injuries occur in the supraspinatus, accounting for more than half of all injuries. Post-operative rehabilitation for rotator cuff injuries requires the use of a specialized positioning bandage.

[0003] Patent application number 202120571147.1 discloses a postoperative shoulder joint fixation device for patients with rotator cuff injuries, including a forearm elevation pad placed on the lower part of the patient's forearm to support the patient's forearm; a fork pad placed in the patient's armpit to abduct the shoulder joint; and a chest strap connected to the forearm elevation pad to fix the forearm elevation pad to the patient's forearm.

[0004] The aforementioned patent takes into account the adjustment of arm height during fixation after rotator cuff injury surgery, but does not consider stretching and traction in other directions. For example, infraspinatus muscle tears can occur in front of or behind the body. After surgery, the arm should be stretched and pulled towards the wound to avoid secondary tearing. The aforementioned patent does not consider this part of the traction. Utility Model Content

[0005] To overcome the problems mentioned in the background art, this utility model provides a rotator cuff injury bandage.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] This application provides a rotator cuff injury bandage, comprising,

[0008] Shoulder positioning component;

[0009] The arm positioning component is located below the shoulder positioning component, and the top outer side of the arm positioning component and the bottom outer side of the shoulder positioning component are fixedly connected.

[0010] The chest strap is fixed at both ends to the front and rear ends of the shoulder positioning piece;

[0011] Underarm supports, installed under the armpits, are used to support the arm; among them,

[0012] The front and rear ends of the top end face of the shoulder positioning component are connected to traction straps, and the other end of the traction strap is provided with a Velcro hook.

[0013] Both the front and rear ends of the chest strap are provided with hook and loop fasteners that are attached to the hook and loop fasteners.

[0014] In the above embodiments, the shoulder positioning device is installed on the shoulder at the surgical site. The arm passes through the arm positioning device at this location, and then the shoulder positioning device and arm positioning device are fixed by binding the chest strap to the other armpit, wrapping it around the chest and back. The armpit support is used to support the arm. In supraspinatus muscle injuries, part of the tear is at the top of the supraspinatus muscle. In this case, in order to adjust the postoperative arm posture, an airbag or air cushion can be installed under the armpit to raise the arm by inflation, pulling the muscles at the tear site together. Similarly, if the teres major or teres minor muscle is injured, because... If the tear is located below the shoulder, the arm should be kept as close to the arm as possible. The airbag or cushion can be removed directly, and the wrist can be fixed in place. If the tear is located on the front of the supraspinatus and infraspinatus muscle groups, pull the traction strap at the back and attach the hook side of the traction strap to the hook side of the front of the chest strap to create a positioning traction effect. Similarly, if the tear is located on the back of the supraspinatus and infraspinatus muscle groups, pull the traction strap at the front and attach the hook side of the traction strap to the hook side of the back of the chest strap.

[0015] Preferably, both the shoulder positioning member and the arm positioning member are made of plastic, and the top outer side of the arm positioning member and the bottom outer side of the shoulder positioning member are rotatably connected by a first hinge.

[0016] Preferably, the underarm support includes a first patch, a second patch, an airbag, and a second hinge. The tops of the first patch and the second patch are rotatably connected by the second hinge, and the airbag is fixedly disposed in the middle of the first patch and the second patch.

[0017] Preferably, the underarm support further includes an underarm support strap fixing ring and an anti-abrasion pad. The underarm support strap fixing ring is fixed to a second patch near the chest. An underarm support strap is fixedly provided at the front end of the second patch, and the other end of the underarm support strap passes through the underarm support strap fixing ring.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0033] Example 1:

[0034] Please see Figure 1 This application discloses a rotator cuff injury bandage, comprising:

[0035] Shoulder positioning component 1, which wraps around the upper part of the rotator cuff muscle group.

[0036] Furthermore, both shoulder positioning component 1 and arm positioning component 2 are made of plastic, such as PVC. Shoulder positioning component 1 and arm positioning component 2 can be divided into large, medium and small sizes according to the patient's body size. They can also be wrapped with gauze before installation to prevent blistering due to friction with the skin caused by poor fit.

[0037] Arm positioning component 2 is located below shoulder positioning component 1. The top outer side of arm positioning component 2 is fixedly connected to the bottom outer side of shoulder positioning component 1. Arm positioning component 2 is used to fix the top of the arm. When in use, the hand needs to pass through arm positioning component 2.

[0038] Furthermore, such as Figure 1 and Figure 5 As shown, the top outer side of the arm positioning member 2 and the bottom outer side of the shoulder positioning member 1 are rotatably connected by the first hinge 3. The top outer side of the arm positioning member 2 and the other positions of the shoulder positioning member 1 are not fixed. By rotating at the position of the first hinge 3, the shoulder positioning member 1 and the arm positioning member 2 can be raised to the corresponding positions when the underarm support 8 is working.

[0039] like Figure 1 , Figure 2 and Figure 4 As shown, the two ends of the chest strap 4 are fixed to the front and rear ends of the shoulder positioning member 1, respectively. The chest strap 4 is used to fix the shoulder positioning member 1 and the arm positioning member 2.

[0040] like Figure 1 As shown, the underarm support 8 is installed under the armpit to support the arm.

[0041] Specifically, such as Figure 3 As shown, the underarm support 8 includes a first patch 81, a second patch 82, an airbag 83, and a second hinge 86. The tops of the first patch 81 and the second patch 82 are rotatably connected by the second hinge 86, and the airbag 83 is fixedly disposed in the middle of the first patch 81 and the second patch 82.

[0042] When in use, the underarm support 8 is placed under the armpit, with the first patch 81 against the inside of the arm and the second patch 82 against the side of the chest. When the arm height needs to be adjusted, the airbag 83 is inflated, and the first patch 81 and the second patch 82 slowly open at the bottom under the action of the second hinge 86 at the top, thereby supporting the arm.

[0043] Furthermore, such as Figure 3 As shown, the underarm support 8 also includes an underarm support strap fixing ring 84 and an anti-abrasion pad 85. The underarm support strap fixing ring 84 is fixed to the second patch 82 near the chest. An underarm support strap 9 is fixedly provided at the front end of the second patch 82, and the other end of the underarm support strap 9 passes through the underarm support strap fixing ring 84.

[0044] To ensure the stability of the underarm support 8, underarm support straps 9 and underarm support strap fixing rings 84 are used for fixation. The principle is the same as that of the chest strap 4, which needs to be wrapped around the chest and fixed on the other side by the underarm support strap fixing rings 84.

[0045] Furthermore, such as Figure 3 As shown, the first patch 81 and the second patch 82 are both arc-shaped pieces that fit the inner side of the arm and the side of the chest; the arc-shaped first patch 81 and the second patch 82 can fit the side of the arm and chest better, increasing comfort.

[0046] Furthermore, such as Figure 3 As shown, the inner curved surfaces of the first patch 81 and the second patch 82 are both provided with anti-wear pads 85.

[0047] The front and rear ends of the top end face of the shoulder positioning component 1 are connected to a traction strap 6, and the other end of the traction strap 6 is provided with a Velcro hook surface 7.

[0048] Both the front and rear ends of the chest strap 4 are provided with hook and loop surfaces 5 that are attached and engaged with the hook and loop hook surfaces 7.

[0049] When the tear is located on the anterior side of the supraspinatus and infraspinatus muscle groups, pull the traction strap 6 at the rear end and attach the hook side 7 of the traction strap 6 to the hook side 5 of the front end of the chest strap 4 to create a positioning traction effect. Similarly, when the tear is located on the posterior side of the supraspinatus and infraspinatus muscle groups, pull the traction strap 6 at the front end and attach the hook side 7 of the traction strap 6 to the hook side 5 of the rear end of the chest strap.

[0050] Furthermore, such as Figure 1 and Figure 2 As shown, wrist fixing rings 10 are provided at both the front and rear ends of the bottom of the shoulder positioning component 1. Based on the above embodiment, in some cases, in order to further ensure the fixation effect, it is necessary to fix the wrist. At this time, a bandage can be passed through the wrist fixing rings 10 on both sides of the shoulder positioning component 1 to fix the wrist, so that the fixation of the wrist position and the fixation structure of the upper shoulder positioning component 1 are linked, and the range of motion of the patient's arm at night is further reduced by the restraint of the wrist, thereby further ensuring the postoperative rehabilitation effect.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
