COMBINATION SPIROMETER AND PEP BREATHING EXERCISER

摘要

A combination spirometer and PEP breathing exercise device is described. The device includes a spirometer with a volumetric air chamber having an atmospheric opening, an exhaust port, and an indicator of inhalation rate or volume; a breathing tube having a proximal end in communication with the exhaust port, a distal end with a mouthpiece, and a conduit between the proximal and distal ends; a one-way check valve adjacent the exhaust port allowing air to flow from the spirometer through the breathing tube to the mouthpiece, but preventing air from being exhausted through the spirometer; and a PEP valve in communication with the breathing conduit, whereby expiration of air from the mouthpiece into the breathing tube above a preset pressure causes the valve to oscillate.

主权项

1. An improved breathing exercise device comprising:
a) a spirometer having an exhaust port; b) a breathing tube having a proximal end in communication with said exhaust port, a distal end with a mouthpiece, and a conduit between said proximal and distal ends; c) a one-way check valve allowing air to flow from said spirometer through said breathing tube to said mouthpiece, but preventing air from being exhausted through said spirometer; and d) a PEP valve in communication with said breathing conduit, whereby expiration of air from said mouthpiece into said breathing tube above a preset pressure causes said valve to open.
