## Abstract

A coupling for connecting an air supply to a respiratory support device has a latching mechanism which prevents the coupling from inadvertently axially displacing from the respiratory support device after they have been mated in a pneumatically discrete path. Non-axial forces are used to disengage the coupling from the respiratory support device. The coupling may include a trailing end adapter which permits rotation of the coupling relative to the air supply rather than to the respiratory support device.

## Claims

### Claim 1

For connecting an air supply to a respiratory support device, a coupling comprising a flexing tubular member having a leading end adapted
for mating said coupling in a discrete pneumatic flow path with the respiratory support device by motion of said leading end in a generally axial direction toward the respiratory support device to bring a leading face of said leading end into abutment with a trailing face of a trailing end of the respiratory support device,
for engaging with the respiratory support device when said flexing tubular member and the trailing face of the respiratory support device are in abutment to prevent said flexing tubular member from axially displacing from the respiratory support device and
for disengaging said flexing tubular member from the respiratory support device by relative rotational motion between said leading end of said flexing tubular member and said respiratory support device about a longitudinal center axis of said flexing tubular member.
