Patent ID: 8147420

Claim:
An apparatus for simultaneously detecting respiratory air temperature information and respiratory air pressure information from a patient, the apparatus comprising: a respiratory air temperature piezoelectric film sensor configured to detect respiratory air temperature information; and a respiratory air pressure piezoelectric film sensor configured to detect respiratory air pressure information; wherein at least a portion of the respiratory air temperature piezoelectric film sensor overlaps at least a portion of the respiratory air pressure piezoelectric film sensor, each of the respiratory air temperature piezoelectric film sensor and the respiratory air pressure piezoelectric film sensor including a non-overlap portion, wherein the non-overlap portion of the respiratory air temperature piezoelectric film sensor does not overlap any portion of the respiratory air pressure piezoelectric film sensor and the non-overlap portion of the respiratory air pressure piezoelectric film sensor does not overlap any portion of the respiratory air temperature piezoelectric film sensor, wherein the non-overlap portion of the respiratory air temperature piezoelectric film sensor is proximate a first end of the apparatus, and the non-overlap portion of the respiratory air pressure piezoelectric film sensor is proximate a second end of the apparatus, the second end substantially opposite to the first end.
