Body limb cast including an outer rigid shell and inner dynamic members in combination with air circulation and massage features

摘要

A cast for supporting a limb includes a rigid outer shell, such as provided as first and second assembleable halves interconnected by a plurality of latches. An inner conforming foam insole is supported within the shell and is interconnected by pluralities of linearly extending passageways in combination with radially extending rings and which communicate with additional breathing holes extending through a cross sectional thickness of the insole for introducing an airflow for relieving patient discomfort. A toe attachable fan unit creates the airflow within the insole in communication with a plurality of vents positioned at upper terminating ends of each of the linear extending passageways. A plurality of airbags encircle the insole and are iteratively inflated and deflated to achieve a pulsing massage effect.
