Abstract

A removable water trap device (110) removes moisture from a respiratory gas stream from a patient interface assembly(140), enabling monitoring of gas within the respiratory gas stream by an analysis bench(120). The device includes a housing(111), an upstream water trap connector(115), and a filter assembly(360). The housing includes a first portion (210) insertably attachable to a tether assembly receptacle (132) to connect the device to the analysis bench for delivering the gas stream via a tether line(136). The upstream water trap connector is attachable to a downstream patient interface connector (141, 143) in a sample flow line (145, 148) of the patent interface assembly for receiving the gas stream via the sample flow line. The filter assembly is insertably contained within the housing and configured to remove moisture from the gas stream, the filter assembly including a downstream water trap connector (116) attachable with the tether line within the tether assembly receptacle. The filter assembly is replaceable independently of replacement of the patient interface assembly.

Description

Background technique [0001] Ventilators deliver a pressurized flow of gas (eg, air and / or a mixture of air and additional (supplemental) oxygen) to the airway of a patient to assist or replace the patient's breathing. The ventilator operates periodically such that gas is provided to the patient during an inspiratory phase (corresponding to inhalation) and gas is received from the patient during a subsequent expiratory phase (corresponding to exhalation). For example, sidestream gas analyzers divert a portion of the patient's breathing gas inhaled and exhaled by the patient during mechanical ventilation or normal breathing (breathing gas flow) to the sensor through a sampling tube (including the patient vent tube interface and extension tubing) (eg Gas Analysis Workbench). [0002] The sensor can be used to detect and analyze at least one gas in the flow of breathing gas, such as carbon dioxide (CO 2 ). However, the presence of moisture often affects the accurate detection o...
