Title: (EN) HEATED RESPIRATORY CONDUIT
(FR) CONDUIT RESPIRATOIRE CHAUFFANT
Abstract: front page image
(EN) This invention is a heated corrugated (21) conduit (7) for use in a respiratory humidification system (5). A heater wire (20) within the conduit reduces the occurrence of condensation or "rain out". The heater wire is spirally wound in a helix or double helix with both ends of the wire available for termination at one end of the conduit.
