Abstract
The device is a disposable compact unit comprising a transparent column with an aperture at its base, an air float within the column and with the column mounted on a closed container. A conduit joins the top of the column to an opening into the container. The container is also equipped with a breathing tube and a variable aperture means for varying the size of another opening into the container. By inhaling through the breathing tube, a patient can judge his capacity for alveolar expansion by the height to which the air float rises. Adjustment to any patient's capacity can be easily made by changing the opening in the variable aperture means.
Claims11
A respiratory exercising device comprising:
- a. a closed hollow container,
- b. a breathing tube in communication with a first opening located at a first position on said container,
- c. variable aperture means for selectively regulating flow of air into said container and located at a second position on said container,
- d. a transparent hollow column generally vertically mounted by its base at a third position on said container and having an access opening into said column near the base of said column, said access opening being external of said container,
- e. conduit means connected at one end to the upper end of said column and in communication at its other end with a second opening in said container, said first opening, said aperture means and said second aperture being in communication within the container;
- and
- f. an air floatable member normally positioned near the bottom of said column above said access opening and adapted for vertical movement within said column in response to flow of air through said access opening on inhaling air through said breathing tube.
