INTERSTITIAL FLUID EXTRACTION SAMPLING MODULE

PROBLEM TO BE SOLVED: To provide a miniaturized interstitial fluid extraction sampling module not to make a user feel uncomfortable when the sampling module is applied to the user. SOLUTION: The sampling module comprises a housing assembly, and a compression ring assembly operably disposed inside the housing assembly. The compression ring assembly comprises a penetrating member, which is present in a target region for extracting the interstitial fluid after penetrating the target region in the body of the user. The compression ring assembly also comprises a compression ring for pressing the body at a first adjacent position in the target region and a movable ring with an adhesive layer, disposed on the distal end of the compression ring. The adhesive layer of the sampling module allows the movable ring to be stuck to the target region at a second adjacent position, and affects the deformation of the target region while the sampling module is used.
