Abstract
The present technology relates to a patient interface for use in delivering breathable gas to a patient. The patient interface may comprise a cushion module and a frame. The cushion module may comprise a cushion and a cushion clip. The cushion clip may be configured to hold the cushion module in a substantially fixed position relative to the frame in use. In some forms, the frame and the cushion module are configured to connect together interlocks between the cushion module and the frame is configured to flex to alter a distance between interlocks, and wherein flexing the frame enables the cushion module to be disconnected from the frame.
Claims19
A patient interface for use in delivering breathable gas to a patient, the patient interface comprising:
- a cushion module;
- and
- a frame,
- wherein the cushion module comprises:
- a plenum chamber pressurisable to a therapeutic pressure of at least 4 cmH2O above ambient air pressure, said plenum chamber forming a plenum chamber inlet port configured to receive a flow of breathable gas at the therapeutic pressure for breathing by the patient;
- and
- a seal-forming structure provided to the plenum chamber, wherein the seal-forming structure is configured to form a seal with a region of the patient's face surrounding an entrance to the patient's airways, said seal-forming structure having an opening therein such that in use the flow of breathable gas is delivered to the entrance to the patient's airways, the seal-forming structure being configured to maintain said therapeutic pressure in the plenum chamber throughout the patient's respiratory cycle in use;
- a first cushion module interlock portion on a first lateral side of a non-patient-facing side of the cushion module;
- a second cushion module interlock portion on a second lateral side of the non-patient-facing side of the cushion module,
- wherein the frame comprises:
- a frame body forming a frame opening allowing the flow of breathable gas to be delivered to the plenum chamber;
- two or more headgear connectors for connecting with headgear, the headgear connectors being positioned on respective lateral sides of the frame body in use;
- a first frame interlock portion on a first lateral side of a patient-facing side of the frame body;
- a second frame interlock portion on a second lateral side of the patient-facing side of the frame body,
- wherein the frame and the cushion module are configured to connect together via a first interlock between the first cushion module interlock portion and the first frame interlock portion and via a second interlock between the second cushion module interlock portion and the second frame interlock portion, and
- wherein the frame is configured to flex to alter a distance between the first frame interlock portion and the second frame interlock portion, and wherein flexing the frame to increase the distance between the first frame interlock portion and the second frame interlock portion enables the cushion module to be disconnected from the frame.
