摘要

abstract chemical optical sensor unit for transcutaneous gas concentration measurement, chemical optical sensor, patient monitoring and / or patient ventilation system and method of conditioning a chemical optical sensor unit for transcutaneous concentration of a gas The present invention relates to a chemical optical sensor unit for transcutaneous measurement of a gas concentration comprising: at least one sensor layer adapted to be irradiated with a predetermined radiation; and at least one gas permeable layer adjacent one side of at least one sensing layer adapted for passing gas whose concentration is to be measured across the gas permeable layer towards the sensing layer; wherein said chemical optical sensor unit is adapted to operate with a contact means between the gas permeable layer and the skin, said contact means comprising a first compound other than water; said chemical optical sensor unit characterized in that said at least one gas permeable layer and said at least one sensor layer are permeable to said first compound; and wherein the chemical optical sensor unit is adapted to measure an optical response of at least one sensor layer whose optical response depends on the gas concentration. The present invention also relates to a system comprising such a chemical optical sensor as well as a method of conditioning a chemical optical sensor unit for measuring the concentration of a gas and a conditioned sensor obtained therefrom. 1/1
