1. A modular elbow frame assembly for a ventilator, configured to provide positive pressure breathing gas to an airway of a patient, the modular elbow frame assembly comprising:
a hose for connection to a ventilator tube,
an elbow that connects the hose and a frame or a patient interface cushion for a delivery of pressurized gas to the airway, and
a quick-release device to detachably connect the elbow and the patient interface cushion;
wherein the elbow includes a first connector and a second connector, a junction between the first connector and the second connector being curved;
wherein the quick-release device is provided on the first connector of the elbow and protruding pieces of the quick-release device are integrally formed with the first connector of the elbow, and the first connector is detachably connected with the frame or the patient interface cushion by the quick-release device;
wherein one end of the hose is detachably connectable to the second connector of the elbow, an other end is connectable to the ventilator tube, and the hose is configured to channel the pressurized gas through the elbow into the airway for respiration;
wherein at least one vent is provided on the elbow, and the at least one vent is configured to release a continuous flow of exhaled gas from the patient to an external environment, wherein the at least one vent on the elbow includes several exhaust holes to facilitate communication between the elbow and the external environment and to allow for the exhaled gas from the patient to be emitted outside the elbow, with:
a maximum total area of the exhaust holes not exceeding 5 cm2;
a weight of no more than 20 g for the elbow;
a portion of an outer wall of the second connector fitting against an inner wall of the hose upon a connection of the elbow with the hose,
wherein the frame includes a fixed opening for connection with the elbow, the fixed opening includes a receiving structure configured to receive the quick-release device on the elbow, and
wherein the fixed opening has an area of the fixed opening at or between 5% to 50% of an external surface area of the frame not facing a face of the patient.
