Document Type and Number:
WIPO Patent Application WO2002034322
Kind Code:
A3
Abstract:
A hand-held breathing device (10) for use by patients having respiratory problems creates a sealed backpressure in the airways of the patient by creating resistance to exhalation. A peep valve (50) is mounted inside a hollow body (12), and a pre-set compression spring (40) is mounted between the valve (50) and an adjustable cap (24) or cam lever (78) in the main body (12) of the device (10). A pair of valve openings extend through the wall of the main body (12), one opening serving as an intake port (42) for inhaling of air by the patient and the second port (44) - for exhalation of carbon dioxide. An intake valve (60) is mounted inside the body (12) between a normally open end of the device (10) and the exhalation valve (50). In one of the embodiments, the device is attached to a nebulizer (88) to facilitate buildup of positive pressure and delivery of medication (104) to the patient's lungs.
