Sealed back pressure breathing device
First Claim
1. 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;
an intake valve mounted between said open end and said exhalation valve;
a compression spring mounted between the exhalation valve and the closed end for regulating resistance to gas flow being exhaled by the patient; and
a means mounted on the second end of the hollow body for adjusting compression of the spring.

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.

6. A sealed back pressure device for assisting respiratory functions of a patient, comprising:
-
an elongated hollow body having a first normally open end, a second normally closed end, an intake port formed through a wall of the hollow body and an exhalation port formed through the wall of the hollow body a distance from said intake port for communicating interior of the hollow body with the atmosphere;
a one-way exhalation valve carried by a supporting bracket and mounted inside the hollow body for allowing exhaust gas to be exhaled through the exhalation port;
an intake valve mounted between said open end and said exhalation valve;
a compression spring mounted between the exhalation valve and the closed end for maintaining a positive back pressure and regulating resistance to gas flow being exhaled by the patient; and
a means mounted on the second end of the hollow body for adjusting compression of the spring, said adjusting means comprising a cap detachably mounted on the second end, said cap providing a first abutting surface for said compression spring, said support bracket providing a second abutting surface for said compression spring, and wherein said open end is provided with a mouthpiece for engagement by lips of the patient.
