Technical field

The invention relates to the technical field of medical devices for chest fixation, and in particular to an adjustable chest fixator.

Background technique

For rib fractures, the current conservative treatment mainly uses rib fixation belts (also called chest straps). External fixation and braking of rib fractures can reduce the patient's pain to a certain extent and play a role in fixing and correcting the ribs. The self-heating rib fixing belt disclosed in the patent with the authorization announcement number CN206403922U includes a rectangular fixing belt body and two shoulder straps spaced on one long side of the fixing belt body. The adhesive fixing structure provided at both ends of the length also includes a heating device arranged on the fixing belt body with an adjustable position. The heating device includes a carbon fiber heating piece and a power supply that supplies power to the carbon fiber heating piece. On the one hand, the utility model can play the role of external fixation and braking of fractures, and on the other hand, it can promote blood circulation and remove blood stasis at the lesion through the self-heating device, thereby alleviating the patient's pain and accelerating the recovery of the fracture patient.
