Blood gas monitoring sensors

摘要

Colorimetric, fiber optic sensors for measuring pH, PCO2 and/or other chemical parameters of the blood. The sensors are fabricated using a single optical fiber, which is provided with a chamber at its distal end containing a pH sensitive dye. Located distal to the chamber is a white reflective surface located within 0.04'' from the end of the optical fiber, which enhances the performance of the sensor.
