Abstract

Pulmonary exerciser device is provided whereby in one embodiment respective inspiratory and expiratory stages are stacked, the former above the latter, in a generally vertical, elongated tubular chamber. The patient pulmonary system is coupled to an intermediate point, and respective balls are carried in the expiratory and inspiratory chambers. Patient inhalation raises the lower ball, and patient exhalation raises the upper ball. Indicia are provided for incentive motivation and measurement of inspiration flow rate. Inspiration only is provided in other devices with provision for measurement and recording. In other devices, expiratory exercise is provided, with or without inspiratory exercise.

Claims

1. Spirometer apparatus comprising:

(a) housing means including integral, operatively associated, alternately effectuated closable openings for inspiratory flow responsive and expiratory pressure means associated therewith;

(b) indicating means, associated with said inspiratory flow means, for quantifying the inspiratory pulmonary condition of the user; and

(c) said expiratory pressure means being of the positive end expiratory pressure type employing a deadweight force means operative against one of said openings in resistance to expiratory flow through the orifice.

2. A pulmonary exerciser comprising:

a housing defining a generally vertical, elongated tubular chamber therein, having ports opening to the atmosphere at end portions thereof, and being divided into respective upper and lower segments at an intermediate region, said upper segment defining a communication passageway to said segment at said intermediate region;

means for coupling a patient'"'"'s pulmonary system to said chamber at said communication passageway;

first passageway blocking means carried in said upper segment, resting over and blocking said passageway during patient inspiration, and being carried above said passageway in said upper segment by the pressure and flow of patient expiration; and

a second passageway blocking means carried in said lower segment, resting on and blocking said bottom port during patient expiration, and being carried above said bottom port by the pressure and flow of patient inspiration.

3. An exerciser as described in claim 2, wherein said first and second passageway blocking means are first and second balls respectively and wherein said housing includes transparent materials defining said lower segment, thereby exposing the position of said second ball to the view of the patient, and wherein said exerciser further includes indicia along said lower segment for evaluation of the extent of travel of said second ball in said lower segment.

4. An exerciser as described in claim 3, and further comprising a lateral extension alongside said lower portion, and marker means, positionable in association with said indicia, for establishing inspiratory goals for the patient, said extension carrying said marker means alongside said lower segment.

5. An exerciser as described in claim 4, and further comprising accumulator means, operable by the patient, for maintaining an interative count of successive inspiratory-expiratory cycles.

6. Apparatus as described in claim 2, wherein said bottom port has means for connection with a source of oxygen of the patient.

7. Apparatus as described in claim 2, wherein said means for coupling includes integral filter means in the flow path between the user and said communication passageway.

8. The exerciser as described in claim 2, including valve means of the mutually actuable type at said communication passageway for optional flow connection between said coupling means and one of:

(a) said upper segment;

(b) said lower segment;

(c) both said upper and lower segments.

9. The apparatus of claim 2, wherein opening means is provided to said first passageway blocking means, for opening said upper segment for removal and replacement of said first passageway blocking means.

10. The apparatus of claim 9, wherein said opening means is of the threaded end cap type.
