The invention discloses a distal
radius functional splint. The distal
radius functional splint comprises a lower splint
assembly, an upper splint
assembly, fastening belts, fastening buttons and connecting belts. The lower splint
assembly and the upper splint assembly are arranged, an upper splint and a lower splint form a functional splint, and through cooperation with first flexible belts and second flexible belts, a clamping operation on the
radius of a user is performed, so that the comfort degree of the user can be increased; ventilation holes are convenient for
convection of inside air and outside air, the ventilation property of the functional splint is guaranteed, ventilation of the radius position can be convenient, and
rehabilitation of radius fracture is facilitated; the upper splint assembly is arranged, after medication, a button switch is pressed down, a heating plate is electrified to operate to heat the inner part of the functional splint, a temperature sensor is used for detecting the temperature value in the functional splint, when the temperature value reaches an upper
limit value, the heating plate stops heating, and when the temperature value reaches a
lower limit value, the heating plate is electrified for operations, so that the situation that the temperature value in the functional splint is in an appropriate range can be guaranteed, the medication effect can be guaranteed, and besides, the
electricity consumption can be reduced.
