Easily formed arm external fixing brace

Abstract

An arm external fixing brace (10), characterized by a thickness (H) of an edge of a mesh panel (12) thereof being greater than a thickness (B) of a central location. Selectively, raw materials of the mesh panel (12) being, according to weight: 60-78% PCL; 20-38% EVA; 2-20% inorganic filler; a thickness of an edge of a large ventilation hole of the mesh panel (12) being less than a thickness between the centers of two adjacent large ventilation holes; multiple fastening substrates (300) being pre-embedded at adjacent horizontal edge locations of the mesh panel (12); two wings of a fastening substrate (300) being provided with side holes (305), two sides of a middle part of a fastening substrate (300) being provided with grooves (302, 303) having symmetrical structures, the middle part of a fastening substrate (300) being provided with a middle hole (304), and a non-return surface (301) being provided at two sides of a circumference of the middle hole (304) inside the grooves (302, 303); two sides of a thumb hole (15) of the mesh panel (12) being tapered surfaces having symmetrical structures. The arm external fixing brace has few components, but simultaneously can prevent adhesion during a molding process so as to facilitate removal from a mold, make clinical operation convenient, and be comfortable to wear, metrics which were previously in conflict with one another.
