Abstract
The present disclosure pertains to a therapeutic gas delivery system (8) including a pressure generator inlet apparatus (10) configured to facilitate filtering of gas drawn into the inlet (14) of the pressure generator (16) of the system. The apparatus comprises a body (12) and a support (24). The body is configured to removably engage the inlet of the pressure generator and receive a particulate filter (18). The body forms an orifice (19) configured to conduct gas that has passed through the filter to the pressure generator inlet. The support is coupled to the body at or near the orifice. The support is configured to extend from the body toward the filter and support the filter. The support is configured to resist collapse of the filter into the orifice caused by gas flowing through the filter to the pressure generator inlet.
