Abstract
An oscillating positive expiratory pressure system including an oscillating positive expiratory pressure device having a chamber, an input component in communication with the chamber, wherein the input component is operative to sense a flow and/or pressure and generate an input signal correlated to the flow or pressure, a processor operative to receive the input signal from the input component and generate an output signal, and an output component operative to receive the output signal, and display an output.
Claims26
An oscillating positive expiratory pressure system comprising:
- an oscillating positive expiratory pressure device comprising a first chamber defining in part an exhalation flow path, and a second chamber isolated from the first chamber;
- a base component having a first thickness;
- a flexible connector surrounding the base component and moveably connecting the base component to the oscillating positive expiratory pressure device, wherein the flexible connector has a second thickness less than the first thickness, wherein the flexible connector and base component separate the first and second chambers;
- a pressure sensor in communication with the second chamber, wherein the pressure sensor is operative to sense a pressure in the second chamber and generate an input signal correlated to the pressure;
- a processor operative to receive the input signal from the pressure sensor and generate an output signal;
- and
- a visual output, wherein the visual output is operative to receive the output signal, and wherein the visual output displays an output.
An oscillating positive expiratory pressure system comprising:
- an oscillating positive expiratory pressure device comprising a first chamber defining in part an exhalation path, and a second chamber isolated from the first chamber;
- a base component having a first thickness;
- a flexible connector surrounding the base component and moveably connecting the base component to the oscillating positive expiratory pressure device, wherein the flexible connector has a second thickness less than the first thickness, wherein the flexible connector and base component separate the first and second chambers;
- a control component operative to control a flow resistance;
- a pressure sensor in communication with the second chamber, wherein the pressure sensor is operative to sense a pressure in the second chamber and generate an input signal correlated to the pressure;
- a processor operative to receive the input signal from the pressure sensor and generate an output signal;
- and
- an output component operative to receive the output signal, and adjust the control component to provide a predetermined flow resistance.
A method of using an oscillating positive expiratory pressure system comprising:
- exhaling into a first chamber of an oscillating positive expiratory pressure device and thereby creating a first pressure;
- controlling a flow resistance in the first chamber with a control component during the exhaling;
- moving a base component having a first thickness by applying the first pressure to the base component during the exhaling and flexing a flexible connector connected between the base component and the oscillating positive expiratory pressure device, wherein the flexible connector has a second thickness less than the first thickness, and thereby applying a second pressure in a second chamber isolated from the first chamber;
- sensing the second pressure in the second chamber during the exhaling with a pressure sensor in communication with the second chamber;
- generating an input signal correlated to the second pressure;
- receiving the input signal with a processor and generating an output signal;
- receiving the output signal with an output component;
- and
- adjusting the control component with the output component to vary the flow resistance in response to the output signal.
