Abstract
An optically based transcutaneous blood gas sensor is provided having a reusable sensor head and a disposable sensing cap. A separate receptacle detachably connects to the sensor head and is attached to a person's skin by a layer of adhesive after a release liner is removed. The sensor head includes a sealed cavity housing one or more LEDs and one or more photodetectors. The disposable cap carries fluorescent targets which produces an amount of fluorescence as a function of blood gas concentration and the fluorescence is sensed by the photodetectors.
