Heat and moisture exchanger adaptor for closed suction catheter assembly and system containing the same
First Claim
1. An adaptor for connecting a closed suction catheter assembly having an aspirating catheter to a heat and moisture exchanger having an aperture formed therethrough, the adaptor comprising:
- a first end in communication with a distal end of the closed suction catheter assembly having an aspirating catheter;
a second end adapted to rotationally engage the heat and moisture exchanger having an aperture formed therethrough; and
the adaptor defining a channel formed through the adaptor so that the aspirating catheter of the closed suction catheter assembly is movable through the adaptor and through the aperture of the heat and moisture exchanger.

Abstract
A heat and moisture exchanger (HME) adaptor for a closed suction catheter assembly having one end in communication with a closed suction catheter assembly and another end configured to rotationally engage and releasably hold the HME is disclosed herein. The adaptor may include a retainer having an aperture that engages projections on the HME to releasably secure the adaptor to the HME. The adaptor may include a retaining ring that may be deformed or rotated to engage or disengage projections on the HME. The adaptor may be used with extended use closed suction catheter assemblies.
