Acoustic spirometer system
First Claim
1. A system using a microphone and a mobile computer device connected to or integrated with the microphone, wherein the mobile computer device includes a processor, the system comprising:
- a transducer through which a user is to exhale or inhale;
said transducer being configured and operable to convert a spirometric flow rate into an audible signal having an audio frequency responsive to the spirometric flow rate, wherein said transducer comprises a rotor comprising a rotor body including a plurality of rotor blades configured to rotate said rotor responsive to a spirometric flow;
the rotor body defining a plurality of rotor chopping openings disposed between the plurality of rotor blades; and
a ring-shaped part from which the plurality of rotor blades project;
wherein the microphone is external to said transducer and is adapted to detect said audible signal having said audio frequency and to convert said audible signal to a corresponding electrical signal having the audio frequency; and
a non-transitory computer readable medium including instructions executable by the processor, wherein said instructions, when executed, cause the processor to receive said corresponding electrical signal, to process the corresponding electrical signal, to derive said audio frequency and to output as a result the spirometric flow rate responsive to said audio frequency.
