Abstract
A breath-based diagnostic device. The device includes an array of multiple gas sensors, a database storage device and a microprocessor. The gas sensors contain material capable of reacting with volatile organic chemicals in the exhaled breath of the subject. The database storage device stores established responses to a variety of disease. The microprocessor compares the response detected by the gas sensors and the database so as to perform the diagnosis.
Claims19
A breath-based diagnostic device comprising:
- (a) a multi-sensor array comprising a plurality of sensory devices each reacting with specific volatile organic vapor in breath to generate a signal, wherein each of the sensory devices reacts with the volatile organic vapor directly and/or through a sensory receptor coated on the sensory device;
- (b) a database storage device for information storage;
- (c) a signal processing unit comprising a oscillator coupled to each of the sensory devices, a frequency counter coupled to the oscillator for counting oscillation frequency, and a digital/analog recorder for recording digital/analog data;
- and
- (d) a microprocessor for receiving a signal generated by the multi-sensor array and comparing the signal with information stored in the database.

A breath-based method for disorder diagnosis, comprising the following steps:
- collecting a breath sample from a subject to be diagnosed;
- reacting the breath sample with a breath-based diagnostic device comprising:
- (a) a multi-sensor array comprising a plurality of sensory devices each reacting with specific volatile organic vapor in breath to generate a signal, wherein each of the sensory devices reacts with the volatile organic vapor directly and/or through a sensory receptor coated on the sensory device;
- (b) a database storage device for information storage;
- (c) a signal processing unit comprising a oscillator coupled to each of the sensory devices, a frequency counter coupled to the oscillator for counting oscillation frequency, and a digital/analog recorder for recording digital/analog data;
- and
- (d) a microprocessor for receiving a signal generated by the multi-sensor array and comparing the signal with information stored in the database to generate a signal;
- comparing the signal with information in the database to determine the physiological state of the subject.
