Pulse oximetry sensor

An oximetry sensor constructed including first and second opposed shell members for engaging the opposite sides of a patient's finger. A coupler releasably connects a pair of LEDs to the first member for projecting light through the finger and a light detector is mounted on the other member for detecting unabsorbed light transmitting through the finger. One of the shell members is mounted for sliding movement on the other for engaging the opposite sides of the patients finger and a coupler retains the shell members in position. In a first embodiment, the LED's are directly releasably coupled to the first member and in a second embodiment a fiber optic cable releasably couples the LED's to the first member.
