Quick donning headgear

摘要

A patient interface for patient ventilation comprises a frame portion and a head strap system. The frame portion is for surrounding oral and nasal regions of a patient. The head strap system is configured for coupling from a left lateral portion of the patient interface, around a posterior skull of a patient, and to a right lateral portion of the frame portion such that in response to donning of the patient interface, the head strap system supplies a securing force to secure the frame portion in a position over nasal and oral cavities of the patient, the head strap is also configured to retain a head-shape when not in use to enable intuitive donning on the patient.
