PORTABLE BODY WARMING DEVICE

摘要

A portable body warming device comprised of a housing (1), a powered blower (19), a combustion chamber (25), an activator (27), a heat exchanger (35) within the housing, a portable hydrocarbon gas fuel source (39) and a battery for powering the blower and activator. The activator initiates combustion of fuel gas in the combustion chamber, and an exhaust vent port discharges combustion byproducts from the housing to serve as the portable warmer.

主权项

1. A portable body warmer to counteract hypothermia, comprising:
a housing having an air inlet port for receiving ambient air, a warmed air discharge port in fluid communication with the inlet port for discharging therapeutic warmed air, and a exhaust vent port; a powered blower for moving air through the housing along a substantially closed airflow path from the air inlet port to the discharge port; a combustion chamber within the housing, the combustion chamber housing a catalyst and being in fluid communication with the exhaust vent port for discharging combustion byproducts from the housing; an activator for initiating combustion of a gaseous fuel in the combustion chamber; a heat exchanger within the housing for transferring heat from the combustion chamber to the closed therapeutic airflow path extending between the air inlet port to the discharge port; a portable hydrocarbon gas fuel source in fluid communication with the combustion chamber; and a battery for powering the blower and the activator.
