Abstract
A quick release/connect mechanism used with nasal and/or oral gas delivery masks. The mechanism attaches to the mask and to the head gear, acting as a connection link. While under normal use the connection remains intact. However, when the release cord is pulled, the mechanism is inclined and becomes free from one of the head gear straps and the connection is broken, allowing the mask to fall quickly from the face. Upon reattachment, the still-adjusted strap simply slips back into place on the mechanism to allow continuation of therapy. Reattachment is accomplished without having to readjust the strap for proper fit.
