An endoscopic imaging system for examining a patient's body cavity includes an endoscope having a distal end, a proximal end and a number of lumens therein. One or more distal gas ports are disposed at or adjacent the distal end of the endoscope and one or more proximal gas ports are disposed proximal to the distal gas ports. Insufflation gas is delivered to the distal gas ports and withdrawn from the proximal gas ports or vice versa such that a gas bubble is formed in the body cavity and travels with the distal tip of the endoscope.

A valve for use in a CPAP system or any stem at a pressure above ambient which vents the pressurised gases from the blower during expiration. Due to the pressure-flow characteristics of the blower this results in the patient having a much lower airway pressure during expiration making breathing easier. The valve includes a movable member which blocks flow from the blower to the patient during exhalation and vents externally. During inhalation gases flow normally from the blower to the patient. Also disclosed is a further application as an antiasphyxia.

An MIE apparatus has a blower, a direction valve, an oscillator, and a mask hose connector. The blower is connected to the direction valve, which is connected to the oscillator, which is connected to the hose connector. During insufflation, a direction valve connects exhaust of a blower to an oscillator, causing positive pressure at the hose connector. During exsufflation, the direction valve connects the blower intake to the oscillator, causing negative pressure at the hose connector. The oscillator is a butterfly valve with a 360° rotating disc. During insufflation, the disc is fixed to steadily modulate the airflow. During exsufflation, the oscillator is inactive or in flutter mode. When inactive, the disc is fixed to allow maximum air flow. In flutter mode, the disc continuously rotates so that the air flow rapidly alternates between maximum and minimum.
