Abstract
The subject invention provides a hand-held medical apparatus (10) for detecting a predetermined component of user breath and producing a breath-component signal over a measurement time. Such breath-component signal may be correlated to a user fat metabolism indicator.
Claims39
A hand-held medical apparatus comprising:
- a. a housing;
- b. an inlet for receiving a sample of user breath;
- c. a sensor for detecting acetone in said user breath using a biomolecule and producing a breath-component signal over a measurement time;
- d. a sensing electrical circuit in electrical communication with said sensor for sensing said breath-component signal, wherein the magnitude of said breath-component signal is a function of the concentration of said acetone in said breath sample to be received into said inlet;
- e. an analog to digital converter in electrical communication with said sensing electrical circuit for converting said breath-component signal to a digital signal;
- f. a microprocessor for processing said digital signal into at least one of a data signal and a user fat metabolism indicator;
- and
- g. a display in electrical communication with said microprocessor for displaying said at least one of a data signal and a user fat metabolism indicator.
5 more elements
A breath analysis apparatus comprising:
- a housing including a conduit through which a sample of user breath flows;
- a sensor, for detecting acetone in at least a portion of said sample and producing a breath-component signal, wherein said sensor comprises a biomolecule;
- a sensing circuit in electrical communication with said sensor for sensing said breath-component signal, wherein the magnitude of said breath-component signal is a function of the concentration of said acetone;
- and
- a processor for processing an output from said sensing circuit, corresponding to said breath-component signal, into a data signal.

A hand-held medical apparatus comprising:
- a. a housing;
- b. an inlet for receiving a sample of user breath;
- c. an electrochemical biosensor for detecting a component of said user breath using an enzyme that selectively targets acetone and producing a breath-component signal over a measurement time;
- d. a sensing electrical circuit in electrical communication with said sensor for sensing said breath-component signal, wherein the magnitude of said breath-component signal is a function of the concentration of said component in said breath sample to be received into said inlet;
- e. an analog to digital converter in electrical communication with said sensing electrical circuit for converting said breath-component signal to a digital signal;
- f. a microprocessor for processing said digital signal into at least one of a data signal and a user fat metabolism indicator;
- and
- g. a display in electrical communication with said microprocessor for displaying said at least one of a data signal and a user fat metabolism indicator.
