A device for interstitial fluid extraction, having a base material formed from a synthetic resin film, a pressure sensitive adhesive layer, a hydrogel layer formed from at least one hydrophilic polymer selected from the group consisting of polyvinyl alcohol and polyvinyl pyrrolidone, and a release layer, wherein the hydrogel layer has an area of a size that the pressure sensitive adhesive layer is exposed from around the hydrogel layer, does substantially not contain a sodium ion and causes no water separation.

Device for interstitial fluid extraction, production process thereof and analyzing process of interstitial fluid using the device

A interstitial fluid collection kit for collecting interstitial fluid extracted via micropores formed in a skin is disclosed. The kit includes a marker sheet that has an adhesive face and that defines a region in which micropores are to be formed; a transparent retention sheet having an adhesive face; and a collecting body that is retained by a part of the adhesive face of the retention sheet and that collects interstitial fluid extracted from the skin.

Interstitial fluid collection method and interstitial fluid collection kit and interstitial fluid collection sheet used for the method

Disclosed are a PVA hydrogel which comprises being obtained by irradiating a polyvinyl alcohol aqueous solution containing a polymer selected from the group consisting of polyvinyl pyrrolidone, a methyl vinyl ether-maleic anhydride copolymer and an isobutylene-maleic anhydride copolymer, with ionizing radiations, a process for preparing the PVA hydrogel, a hydrogel laminate using the PVA hydrogel, a process for preparing the hydrogel laminate, and a hydrogel wound-dressing material using the PVA hydrogel.
