DEVICE AND METHOD FOR SAMPLING AND MEASURING BIOFLUID COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a device for determining the concentration of at least one kind of object component in contact biofluid by sampling the respective components of the biofluid by coming into contact with the biofluid. SOLUTION: This device has at least one micro-piercing member, which is used to intrude into the skin to a prescribed depth and comes into contact with the biofluid, a component sampling means, and a component measuring means. The component sampling means has a component transfer medium such as a hydrophilic gel material, and the respective sampled components are transferred to the measuring means from the micro-piercing member by the transfer medium. The measuring means has an electrochemical cell having at least one porous electrodes, and the sampled component of at least one kind is fed into the electrochemical cell through the electrode. In addition, a method for sampling the respective components in the skin so as to measure the respective sampled components and a kit for putting this invention into practice are provided.
