to allow a portion of the cover 345 to protrude through the face stock a release liner can be placed on the other side of the base material from the face stock in order to protect adhesive on that side the release liner can be removed when the sensor is attached to a patient during reprocessing the sensor assembly 300 can be disassembled into its constituent parts for example the face stock 315 can be detached from the base material 305 to expose the sensor portion 310 the sensing components 320 325 on the sensor portion can be replaced individually or together as part of the sensor portion 310 in one embodiment the sensing components 320 325 are replaced individually with at least some of the sensor portion 310 retained after replacing the sensing components the sensor can be reassembled the base layer 305 face stock 315 and or cover 345 can be replaced or reused new adhesive can be applied to the sensor assembly 300 and a release liner attached once reassembled the sensor assembly 300 can be sterilized and then packaged for use fig3 b illustrates the disposable sensor of fig3 a attached to a tissue site and a cable assembly the cable assembly 350 comprises a cable and a connector attachable to the sensor assembly 300 via its sensor connector 330 the cable assembly 350 operatively connects the sensor assembly 300 to a patient monitor the cable portion 350 can also be reprocessed with the sensor assembly 300 and replaced if defective however as the cable portion generally receives less wear than the.
