AI Technical Summary

Benefits of technology

The present invention is about a positive respiratory pressure apparatus that can be used for performing positive expiratory pressure therapy. The apparatus includes a valve that can adjust the resistance to fluid flow in both inhalation and exhalation directions. This allows for continuous adjustment of the resistance to the patient's needs during therapy. The apparatus can be used alone or in combination with other devices such as a mask or mouthpiece, or an aerosol delivery apparatus. The invention also includes a method for performing positive expiratory pressure therapy using the apparatus. The technical effects of the invention include improved respiratory therapy and the ability to deliver a substance to the patient's respiratory system in a safe and effective way.

Problems solved by technology

An orifice that is too large may result in a short exhalation that will not produce proper expiratory pressure.
An orifice that is too small may result in a longer expiratory phase that raises the pressure above approximately 20 cm H2O and ultimately increases the work of breathing.

Embodiment Construction

[0081]FIGS. 1-3 show one embodiment of an assembly 10 for performing positive expiratory pressure (PEP) therapy where the assembly incorporates a positive pressure (PP) device having a PP valve 12. The assembly 10 includes an aerosol delivery apparatus, such as an aerosol holding chamber 14, and a patient respiratory system interface, such as a mouthpiece 16 and / or mask attachable to the output end of the aerosol delivery apparatus. The PP valve 12 may be located on the aerosol delivery apparatus or the patient respiratory system interface. The assembly 10 combines the aerosol delivery apparatus, mouthpiece, and PP valve into a tool for use in both positive expiratory therapy and administration of a substance, such as a medicament, in aerosol form. Any aerosol delivery apparatus suitable for generating an aerosol of the desired substance may be used.

[0082]In the embodiment of FIGS. 1-3, a backpiece 18 is attachable to the inlet 20 of the aerosol holding chamber 14. A metered dose in...

Abstract

An apparatus and method for performing positive pressure (PP) therapy alone or in combination with an aerosol delivery apparatus. The positive pressure apparatus includes a positive pressure valve having a continuously variable respiratory window. The PP valve may be associated with a patient respiratory system interface alone, such as, but not limited to, a mask or mouthpiece, or in combination with an aerosol delivery apparatus.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. application Ser. No. 09 / 833,019, filed Apr. 11, 2001, now U.S. Pat. No. 6,557,549, which claims the benefit of U.S. Provisional Application No. 60 / 196,555, filed Apr. 11, 2000, wherein the entirety of each of the aforementioned applications are incorporated herein by reference.FIELD OF THE INVENTION[0002]The invention relates to an apparatus and method for performing Positive Expiratory Pressure (PEP) therapy. More particularly, this invention relates to a method and apparatus for performing PEP therapy alone or in conjunction with an aerosol delivery apparatus.BACKGROUND[0003]PEP therapy is used primarily in pulmonary secretion removal. Devices used to perform PEP therapy provide positive pressure during expiration. The patient or user exhales against a fixed orifice resistor and generates a pressure ranging approximately from 10-20 cm H2O. The resistance orifice is an important consideration an...
