Abstract
A respiratory gas flow coupling includes a device connector having a female receptacle or male nipple with a side-oriented leak path. A patient accessory connector has a male nipple or female receptacle adapted to connect with the female receptacle or male nipple of the device connector. The patient accessory connector seals the side-oriented leak path of the female receptacle or male nipple of the device connector when the patient accessory connector is connected with the device connector. The side-oriented leak path is disposed at a position such that a shorter male nipple or female receptacle of an incompatible patient accessory connector which is shorter than the male nipple of the patient accessory connector does not seal the side-oriented leak path when the incompatible patient accessory connector with the shorter male nipple is connected with the device connector.
