Non-contact respiration monitor
First Claim
1. A respiration monitoring device comprising:
- a body having an inlet and an outlet in fluid communication;
a connector having a sealing surface on said air outlet end of said body, wherein said sealing surface is adapted to permit fluid-tight engagement with an air input orifice of an air filter canister of a gas mask;
a detector disposed between said inlet and said outlet comprising a flap-valve switch actuatable by respiration air of a wearer of said gas mask;
a logic circuit configured to report respiration actuated movement of said flap-valve; and
a battery for powering said logic circuit.

Abstract
This invention relates to non-contact monitoring devices, and more particularly, non-contact respiration monitoring devices. According to the invention there is provided a monitoring device having a body defining an air monitoring channel between an air inlet and an air outlet. Disposed in monitoring channel is a respiration detection means, such as a flap-valve, which operates with associated logic circuitry to report the presence or absence of respiration via visual and audible displays. The device may be configured to attached, or be integrally connected to, the air input orifice of an air filter canister of a gas mask or the like. Alternatively, the device may be associated with the air output orifices or valves of a gas mask or the like.

14. A non-contact respiration monitor comprising:
-
a monitor body having an inlet, an outlet and a fluid monitoring chamber passing therethrough;
said monitor body having a connector having a sealing surface on said outlet end configured to permit fluid-tight engagement with an air input orifice of an air filter canister of a gas maskan air flow actuated flap-valve switch, said switch being actuated by the respiration of a wearer of said gas mask; a battery powered logic circuit operatively associated with said flap-valve switch; and a means for reporting the presence or absence of respiration. - View Dependent Claims (15, 16, 17, 18)

19. A method of using a respiration monitor comprising:
-
disposing a monitor body having an inlet, an outlet and a fluid monitoring chamber passing therethrough in fluid tight contact with the outside end of a gas mask;
whereby respiration of a wearer of said gas mask draws air through said monitor, then into said gas mask, and then to the lungs of the user;activating a battery powered logic circuit configured to sense air movement in said fluid monitoring chamber; detecting the presence or absence of air passing from said inlet to said outlet, and determining the presence or absence of respiration. - View Dependent Claims (20, 21, 22, 23)
