PATIENT INTERFACING SYSTEM AND METHOD TO PREVENT WATER CONTAMINATION

摘要

Described herein is a patient interfacing (10) for sampling the inspired and expired gases of a patient and removing moisture from the sample. In one embodiment of the present invention, a patient link (20) receives the gases from the patient's airway circuit (11) and a vaporization section (30) vaporizes condensed moisture in the sample. A separator section (40) allows the vaporized moisture component of the sample to exit the patient interfacing system (10) before the gas sample reaches the monitoring instrument (12). A filter (70) may also be utilized to prevent condensed moisture, particulates and liquids from entering the monitoring instrument (12). Thus, the patient interfacing system (10) of the present invention provides a reliable, cost effective and efficient means for delivering gas samples to a monitoring instrument (12) which reduces or prevents water condensation inside the gas analysis portion of the monitoring instrument (12).
