Abstract
A calibrating device for an optical catheter is provided in order to calibrate the catheter for use in a catheter oximeter system. The calibrating device includes a tube having a reference block therein which is spring-loaded into compliant engagement with the distal end of the catheter carrying the fiberoptic light transmitting and receiving guides. A releasable strap tightly secures the catheter to the calibrating device. The packaged catheter is therefore ready for calibration by simply removing the proximal end thereof from a sealed package while the calibrating device and major length of the catheter remain in their sealed and sterilized condition and connecting it to a processor for performing the calibration operation.
