[0021] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] In order to provide stable support for the patient's upper limbs and ensure blood circulation in the upper limbs, a device is designed to protect the affected shoulder joint, such as Figure 1 As shown, the support comprises a support seat 1, which is worn on the patient's waist through a waist belt 2. The support seat 1 is provided with a contoured groove 3 for accommodating the patient's forearm. The contoured groove 3 has a hand-proximal end 31 and an elbow-proximal end 32, and the width of the contoured groove 3 gradually increases from the hand-proximal end 31 to the elbow-proximal end 32. The support seat 1 is fixed to the patient's waist through the waist belt 2, and the waist strength is used to stably support the upper limbs to avoid oppression on the neck and shoulders. The contoured groove 3 for placing the forearm is set to a structure that is narrow in front and wide in the back according to the shape of the forearm to ensure stable placement of the upper limb, eliminating the setting of the traditional shoulder strap, and can prevent the problem of blood circulation in the upper limb caused by lifting the humerus, and the supporting force is sufficient.

[0023] A waist belt 2 is passed through the two sides of the bracket 1, one end of the waist belt 2 is set on the bracket 1, and the other end is provided with a Velcro 21. Buckles for tying the waist belt 2 are provided on both sides of the bracket 1, one end of the waist belt 2 is fixed in the buckle, and the other end is sewn with a Velcro 21. The Velcro 21 at the ends of the waist belt 2 on both sides cooperate with each other and can be adjusted according to the size of the patient's waist, so that the bracket 1 can be stably worn on the patient's waist.

[0024] The contoured groove 3 is inclined from the hand-proximal end 31 to the elbow-proximal end 32, and the inclination angle is 0-30 degrees, so as to avoid the left-right displacement of the patient's forearm and ensure effective fixation.

[0025] In order to make the upper limb placement more comfortable, memory foam can also be padded in the contoured groove 3. The memory foam is a polyether polyurethane foam sponge with slow rebound mechanical properties. The higher the density, the better the effect of fitting the forearm curve.

[0026] In order to prevent the forearm elbow from coming out of the contoured slot 3, a stopper 4 for preventing the patient's forearm from coming out is provided at the proximal elbow end 32. To ensure comfort, the stopper 4 is an elastic net, which is fixed on the bracket 1 by screws.
