Abstract
Abstract A hand-held breathing device 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 is mounted inside a hollow body, and a pre-set compression spring is mounted between the valve and an adjustable cap or cam lever in the main body of the device. A pair of valve openings extend through the wall of the main body, one opening serving as an intake port for inhaling of air by the patient and the second port—for exhalation of carbon dioxide. An intake valve is mounted inside the body between a normally open end of the device and the exhalation valve. In one of the embodiments, the device is attached to a nebulizer to facilitate buildup of positive pressure and delivery of medication to the patients' lungs.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
109 words
A sealed back pressure device for assisting a respiratory function of a patient, comprising: an elongated hollow body having a first normally open end, a second normally closed end, an intake port and an exhalation port; a one-way exhalation valve mounted inside the hollow body for allowing exhaust gas to be exhaled through the exhalation port; a compression spring mounted between the exhalation valve and the closed end for regulating resistance to gas flow being exhaled by the patient; a means mounted on the second end of the hollow body for adjusting compression of the spring; and an intake valve mounted between said open end and said exhalation valve.
