Abstract
A respiratory care system includes a user interface. A flow indicator is moveable in response to inhalation and/or exhalation, or both, by a user through the user interface. An electronic indicator is operable in response to an electronic signal transmitted in response to the movement of the floe indicator. Methods of use and assembly are also provided.
Claims32
A respiratory delivery system comprising:
- a holding chamber having an input end, an output end comprising a user interface having an outlet and an interior volume of space defined between said input and output ends;
- a mechanical flow indicator moveable between at least first and second positions in response to inhalation or exhalation by a user through said outlet, wherein said mechanical flow indicator is configured with a first conductive region;
- a seat comprising a second conductive region;
- a circuit comprising a switch, wherein said first conductive region of said mechanical flow indicator is moveable into or out of contact with said second conductive region of said seat, wherein said switch is closed or opened, as said mechanical flow indicator is moved between said first and second positions;
- and
- an electronic indicator operable in response to an electronic signal transmitted by said circuit in response to said switch being opened or closed by the movement of said mechanical flow indicator, wherein said mechanical flow indicator comprises a deformable flap, wherein said first conductive region is arranged along a free end of said deformable flap.
