Abstract
A method for detecting an analyte in a bodily fluid includes placing the detector in contact with at least one metabolite resulting from the metabolism or degradation of the analyte. The contact between the detector and the metabolite produces an optically detectable signal. The detection method includes the detection of the metabolite only in gas form, said metabolite in gas form coming from the evaporation of at least a part of said metabolite. The detection is also carried out without contact between the bodily fluid and the detector. A dressing for implementing the detection method is also described.
Claims15
A method for detecting an analyte in a bodily liquid fluid, comprising:
- placing a dressing in contact with a human or animal skin, said skin excreting said bodily liquid fluid, said bodily liquid fluid including said analyte, said dressing including at least a detector, said detector being located above the human or animal skin;
- waiting for said analyte to either degrade or metabolize, and in doing so release a Volatile Organic Compound (VOC), said VOC released from the analyte being in a liquid form;
- waiting for said liquid form of the VOC to evaporate into a gaseous organic compound;
- and
- detecting said gaseous organic compound with said detector, wherein
- said detector is an optical detector, where the optical detector is configured such that the presence of a gaseous form of the VOC modifies optical properties of the optical detector, and
- said detector does not contact said bodily liquid fluid.
