[0002] Patients with hemiplegia due to stroke will experience shoulder subluxation. When the patient lies on his back, the shoulder joint will dislocate posteriorly, causing the shoulder joint to be out of its functional position, which will not only have an adverse effect on the patient's condition, but also aggravate shoulder pain. Utility Model Content
[0003] The utility model aims to provide a shoulder dislocation preventer to solve the technical problem in the prior art that patients with hemiplegia of one limb due to stroke will suffer from shoulder subluxation, and the joint will dislocate posteriorly when the patient lies on his back, causing the shoulder joint to be out of the functional position.
[0004] In order to solve the above technical problems, the utility model specifically provides a shoulder dislocation preventer, comprising a sleeve worn on the affected limb, wherein the sleeve is arranged as a double-layer structure, and a gap for installing an airbag is arranged between the double-layer structures;
[0005] A shoulder airbag and an arm airbag are respectively arranged in the gap at the shoulder joint and the arm position;

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] like Figure 1 As shown, the utility model specifically provides a shoulder dislocation preventer, comprising a sleeve 1 worn on the affected limb, the sleeve 1 being arranged as a double-layer structure, and a gap for installing an airbag is arranged between the double-layer structures;
[0031] A shoulder airbag 2 and an arm airbag 3 are arranged in the gap at the shoulder joint and the arm 11 respectively;
[0032] The shoulder airbag 2 is used to elevate the shoulder joint when the patient lies flat, so as to prevent posterior dislocation of the shoulder joint;
[0033] The arm airbag 3 is in the shape of a long strip, extending along the affected limb, and can straighten the affected limb when inflated.
[0034] When in use, first the sleeve 1 is worn on the patient's affected limb. Inflate the arm airbag 3, and the airbag is stretched straight to make the patient's arm 11 straight.
[0035] When the patient lies flat, air is inflated into the shoulder airbag 2. The expansion of the shoulder airbag 2 can lift the patient's shoulder joint to prevent posterior dislocation of the shoulder joint and keep the shoulder joint in a functional position, that is, a normal physiological position, which is beneficial to the patient's recovery and relieves shoulder joint pain.
[0036] When the patient lies on his side, the shoulder joint does not need to be raised; the shoulder airbag 2 is deflated and shrunken.
[0037] Optionally, the shoulder airbag 2 can be configured as an electrically inflatable airbag or a pressure airbag.
[0038] A pressure sensor is provided in the pressure airbag to detect the pressure in the shoulder airbag 2. Each person's shoulder joint has a corresponding weight, and the weight value is set.
[0039] When the patient lies flat, the pressure in the shoulder airbag 2 is less than the set pressure, and air is inflated into the shoulder airbag 2 to raise the shoulder joint.
[0040] When the patient lies on his side, the pressure in the shoulder airbag 2 is greater than the set pressure, and the shoulder airbag 2 is automatically deflated.
[0041] Furthermore, when the arm airbag 3 is inflated, the inner side of the airbag is higher than the outer side, so as to support the arm 11 in a position with the palm facing upward.
[0042] That is, in a natural state, the human arm 11 is turned inward, with the palm facing inward.
[0043] When the arm airbag 3 is inflated, the expansion height of the inner side is greater than the expansion height of the outer side. Such an arm airbag 3 with a higher inner side and a lower outer side can make the arm 11 flip outward and support the arm 11 in a position with the palm facing upward.
[0044] like Figure 5 As shown, the left side is the little finger side, and the right side is the thumb side. The arm airbag 3 is higher on the left side and lower on the right side, so that the arm 11 is turned outward and supported in a position with the palm facing up.
[0045] Furthermore, the study found that the most comfortable shoulder abduction angle is different for patients in different lying positions.
[0046] For example, when lying flat, it is more comfortable when the shoulder abduction angle is around 45°.
[0047] When lying on your side, the shoulder abduction angle is more comfortable at 80°-100°.
[0048] Since the patient is in a state of hemiplegia, he is unable to adjust the shoulder abduction angle on his own.
[0049] For this purpose, we arrange an axillary airbag 4 at the patient's axillary area to adjust the shoulder abduction angle to adapt to the patient's different lying positions.
[0050] The details are as follows:
[0051] When the patient lies flat, an appropriate amount of air is inflated into the axillary airbag 4 so that the axillary airbag 4 supports the shoulder to be abducted 40°-50°;
[0052] When the patient lies on his side, more gas needs to be filled into the axillary airbag 4 compared to when the patient lies flat, so that the axillary airbag 4 supports the shoulder abduction by 80°-100°.
[0053] There are two types of side-sleeping. One is that the body is almost perpendicular to the bed, at which time the shoulder abduction angle is between 80°-90°; the other is lying on the healthy side, with the body tilted and the chest tilted downward, at which time the shoulder abduction angle is between 90°-100°.
[0054] Furthermore, if Figure 3 As shown, in order to accelerate the patient's recovery, relieve the patient's shoulder joint pain, and promote blood circulation and remove blood stasis in the affected limb, a net bag 5 is provided on the inner side of the layer of the sleeve 1 close to the affected limb for placing Chinese herbal preparations for hot compress. The Chinese herbal preparations are attached to the affected limb through a thin layer of the net bag.
[0055] Chinese herbal preparations for hot compresses can be Si Zi San, Huo Xue Tong Luo Fang, Shen Tong Zhu Yu Tang, etc. Adding iron supplements can generate heat like a steam eye mask and speed up the effect of the medicine.
[0056] Furthermore, in order to prevent the sleeve 1 and the airbag from being separated from the affected limb or being displaced, a first elastic fixing belt 6 is connected to the shoulder position of the sleeve 1.
[0057] Both ends of the first fixing belt 6 are fixedly connected to the sleeve 1, and the first fixing belt 6 is passed around the patient's chest to fix the sleeve 1 and the airbag on the affected limb.
[0058] The first fixing belt 6 is configured as a long cloth belt, and Velcro is provided at both ends of the cloth belt to facilitate adjusting the tightness of the first fixing belt 6 .
[0059] Furthermore, in order to facilitate the patient's walking, a second fixing belt 7 is provided for hanging the affected limb on the patient's neck to support the affected limb.
[0060] like Figure 2 and Figure 4 As shown, the two ends of the second fixing belt 7 are respectively provided with a hook surface 8 and a first fleece surface 9 of the Velcro, and the middle position of the second fixing belt 7 is provided with a second fleece surface 10 .
[0061] When the hook surface 8 is bonded to the first rough surface 9 at the end, a large annular belt is formed. The large annular belt has a larger diameter and can be used to support the affected limb.
[0062] When the hook surface 8 is bonded to the second fleece surface 10 in the middle, two overlapping small annular belts are formed, which can be used as a collar around the patient's neck to prevent the second fixing belt 7 from being lost.
[0063] That is, the second fixing belt 7 can be wrapped around the patient's neck twice, the hook surface 8 is bonded to the second fleece surface 10 in the middle, and the second fixing belt 7 is used as a collar.
[0064] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
