METHOD AND APPARATUS FOR CONDITIONING GAS FOR MEDICAL PROCEDURES

摘要

This invention is an apparatus for conditioning gas for use in a medical procedure, comprised of a housing (100) defining a chamber (120) having an entry port, and an exit port. The housing (100) contains a humidification means comprising at least one liquid retaining layer disposed within the chamber (120); and a humidity sensor for sensing humidity of gas exiting the chamber. A monitoring circuit is connected to the humidity sensor that detects when the chamber (120) require s a recharge of liquid based on the humidity of the gas, and generates a recharge signal. A charging port (190) provides access into the chamber (120) to recharge with water. Alternatively, a backup container (300) of liquid continuously supplies liquid to the humidification means. A heating element, and temperature sensor are also disposed within the chamber (120). A control circuit (140) further regulates the temperature of the gas exiting the chamber (120).
