Abstract
A medical device includes a user interface component and an energy harvesting system coupled to the user interface component. The energy harvesting system energy includes a harvesting component, a power storage device connected to the energy harvesting component and an output is coupled to the user interface and operably connected to the power storage device. A method of using the medical device is also provided.
Claims16
An oscillating positive expiratory pressure device comprising:
- a mouthpiece and a housing, wherein at least one of the mouthpiece and housing define separated first and second chambers having differential flow, pressure and/or temperature properties;
- an energy harvesting component disposed between the first and second chambers and operable to generate electrical energy in response to the differential flow, pressure and/or temperature properties of the first and second chambers, wherein the first and second chambers define inhalation and exhalation pathways respectively;
- a power storage device connected to the energy harvesting component and operable to store the electrical energy received from the energy harvesting component;
- and
- an output operably connected to the power storage device.
An oscillating positive expiratory pressure device comprising:
- a mouthpiece and a housing, wherein at least one of the mouthpiece and housing define separated first and second chambers having differential flow, pressure and/or temperature properties;
- a linear generator comprising a magnet disposed inside a conductive coil disposed between the first and second chambers and operable to generate electrical energy in response to the differential flow and/or, pressure properties of the first and second chambers;
- a power storage device connected to the coil and operable to store the electrical energy received from the coil;
- and
- an output operably connected to the power storage device.
A method of using an oscillating positive expiratory pressure device comprising:
- inhaling and/or exhaling into a mouthpiece coupled to a housing, wherein at least one of the mouthpiece and housing define separated first and second chamber, wherein the first and second chambers define inhalation and exhalation pathways respectively, wherein one or both of the inhaling and exhaling creates differential flow, pressure and/or temperature properties in the first and second chambers;
- harvesting energy with an energy harvesting component disposed between the first and second chambers and generating electrical energy in response to the user inhaling and/or exhaling into the mouthpiece;
- storing the electrical energy in a power storage device connected to the energy harvesting component;
- and
- providing electrical energy from the power storage device to an output.
A method of using an oscillating positive expiratory pressure device comprising:
- inhaling and/or exhaling into a mouthpiece coupled to a housing, wherein at least one of the mouthpiece and housing define separated first and second chamber, and wherein one or both of the inhaling and exhaling creates differential flow and/or, pressure properties in the first and second chambers;
- harvesting energy with a linear generator comprising a magnet disposed inside a conductive coil disposed between the first and second chambers and generating electrical energy in response to the user inhaling and/or exhaling into the mouthpiece by moving the magnet inside the coil;
- storing the electrical energy in a power storage device connected to the coil;
- and
- providing electrical energy from the power storage device to an output.
