Proximal humerus fracture brace

The proximal humerus fracture brace comprises a bearing assembly used for bearing an arm of a patient, and a supporting assembly used for supporting the arm, a wearing assembly used for wearing the bearing assembly on the body of the patient and a reinforcing assembly used for further improving the wearing effect of the bearing assembly are arranged on the surface of the bearing assembly. The bearing assembly comprises a clamping support used for bearing the upper arm and a lower arm part used for supporting the front arm. According to the proximal humerus fracture brace, the bearing assembly, the supporting assembly, the wearing assembly and the reinforcing assembly form the proximal humerus fracture brace, the fracture position can be rapidly fixed, and rapid adaptive adjustment can be conducted according to use requirements; the bearing assembly is uniformly stressed through the inflation assembly; through cooperation of the wearing assembly and the reinforcing assembly, the bearing assembly does not shift
