Abstract:
1. Apparatus for controlling the delivery of a respiratory gas to a user comprising: heating means including a heating element for heating a respiratory gas to a temperature sufficient to be delivered in a flow path to a user at a predetermined temperature level; conveying means for moving said respiratory gas in a flow path and at a predetermined rate to a user; said conveying means including a delivery tube having a first portion containing said heating element, and being coupled at an end thereof to means for administering said respiratory gas to a user; said heating element having a distal end portion positioned adjacent to said delivery tube coupling to said means for administering respiratory gas to a user; said delivery tube having a second portion isolated from contact with said respiratory gas flow path and extending substantially directly adjacent to a point at which said respiratory gas is administered essentially directly to said user; means for administering said respiratory gas to said user at said predetermined flow rate and at said predetermined temperature level; and monitoring means for monitoring the temperature of said respiratory gas at a point at which said respiratory gas is administered essentially directly to said user, said monitoring means including a sensor carried within said second portion of said delivery tube adjacent to an end wall thereof adjacent to said point at which said respiratory gas is administered essentially directly to said user and thereby positioned in thermal contact with said respiratory gas but out of said respiratory gas flow path.
