Sealed back pressure breathing device

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 and an exhalation port;
• 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;
• 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.
