NEGATIVE GAUGE PRESSURE DYNAMIC CONVECTION SYSTEM HAVING INNER AND OUTER AIRFLOW REGULATED ENVIRONMENTS FOR ARTIFICIAL LIMB AND ASSOCIATED METHODS

摘要

The forced convection system includes a limb socket configured to define an outer regulated airflow environment between the socket and the liner, and an airflow generation device coupled to an inner airflow regulated environment and the outer regulated airflow environment and configured to generate airflow therein. A convection control system including convection control circuitry is configured to adjust the airflow generation device and configured to dynamically control airflow to maintain negative gauge pressure therein and transfer thermal energy therein to an external atmosphere. The convection control system further includes a rising edge triggered negative gauge pressure regulation device including pressure control circuitry and an associated valve configured to control airflow proportioning devices to open respective airflow paths to the regulated airflow environments. The convection control system is configured to provide regulated differential pressure forced airflow convection to the regulated airflow environments.
