METHOD OF EXTRACTING INTERSTITIAL FLUID

PROBLEM TO BE SOLVED: To provide a miniaturized device capable of continuously and stably extracting an interstitial fluid sample. SOLUTION: The method of extracting the interstitial fluid (ISF) from a target region of the body of a user comprises a process of adhesively attaching a movable ring of a sampling module for extracting the interstitial fluid to a position adjacent to the target region in the body, a process of attaching the sampling module to the movable ring, and a process of attaching the sapling module to the body. After that, the target region is penetrated by a penetrating member of the sampling module, and after that, another adjacent part of the target region is pressed by a compression ring of the sampling module. Then, the interstitial fluid is extracted from the target region via the penetrating member of the sampling module. COPYRIGHT: (C)2007,JPO&INPIT
