Abstract
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.
Claims20
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.
An improved breathing exercise device comprising:
- a) a spirometer including a volumetric air chamber having an atmospheric opening, an exhaust port, and an indicator of inhalation rate or volume;
- 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 adjacent said exhaust port 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) an oscillating 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 oscillate.
A breathing exercise device useable as both a spirometer and a PEP respirator comprising:
- a) a spirometer having an exhaust port;
- b) a PEP module having a tubular housing with an inlet, an outlet, and a conduit, a PEP valve extending from said housing in communication with said conduit, and a check valve in said conduit between said inlet and said PEP valve, said inlet being attachable to said spirometer exhaust port;
- and
- c) a breathing tube having a proximal end attachable to said module outlet and a distal end with a mouthpiece.
