Abstract
The present invention includes a system and device for aiding in the diagnosis of a physiological abnormality resulting in detectable, measurable variations in contents of breathed air. The system includes a handheld unit defining an airway, wherein the airway includes a plurality of sensors adapted to measure a plurality of parameters related to the presence of a physiological abnormality. The system further includes a control unit remotely connected to the handheld unit. The control unit includes a controller adapted to receive input signals from the handheld unit and remit output signals in response thereto. The output signals are usable by a user in determining the presence or absence of a physiological abnormality. The control unit further also can include a display adapted to display the output signals to a user thereby easing the determination of the physiological abnormality. The system further includes a mouthpiece selectively connectable to the handheld unit. The mouthpiece can include a filter adapted to substantially prohibit the passage of germs into the airway of the handheld unit.
