Patent ID: 8801609

Claim:
An apparatus for simultaneously measuring basal metabolic temperature, waking peak flow, plus one or more of heart rate, blood oxygen percentage and saliva acidity; the apparatus comprising: a fluid channel for passing exhaled fluid and having an impellor disposed therein for measuring peak volumetric flow of fluid through the fluid channel by sensing a rotating magnet within the impellor with a field-effect transistor counting the numbers of rotations per second of the impellor; a mouthpiece positioned in line with the fluid channel for insertion into an individual's mouth and forming a seal with the mouth and directing exhaled fluid into the fluid channel; a rapid thermometer probe with a metallic tip disposed in the mouthpiece for measuring basal metabolic temperature at a sublingual location when the mouthpiece is inserted into the mouth; a second probe with a metallic tip disposed in the mouthpiece for measuring saliva acidity at a sublingual location when the mouthpiece is inserted into the mouth; and, a digital memory for storing measured values for basal metabolic temperature, waking peak flow, and saliva acidity (Ph).
