Embodiment Construction

[0086] The specific implementation of the interstitial fluid analyzer of the present invention will be described in detail below with reference to the accompanying drawings.

[0087] figure 1 It is a perspective view of the external appearance of the analyzer of this embodiment. The analysis device 1 related to this embodiment is such as figure 1 As shown, it consists of a device main body 10 and an analysis kit 20 . The analysis kit 20 is composed of an analysis kit 30 and a collection material 50 . This analysis device 1 is used to collect tissue fluid from the subject and collect it in the collection material, and then obtain the concentration of analytes (glucose and sodium ions) in the tissue fluid contained in the collection material, so as to obtain the area under the curve corresponding to 1 hour blood glucose (AUC: Area under the curve) value. More specifically, this analysis device 1 is used as follows: First, micropores are formed on the skin of the subject, and...

Abstract

A method for analyzing an analyte in tissue fluid is disclosed. The method comprises: placing a collecting member in contact with the skin of a subject, wherein the collecting member is configured to collect and retain tissue fluid containing the analyte from the subject; collecting tissue fluid from the subject into the collecting member; detaching the collecting member from the skin of the subject; causing the analyte in the tissue fluid collected by the collecting member to diffuse in a liquid by supplying the collecting member with the liquid; and detecting the analyte diffused in the liquid. An analyzer for analyzing an analyte in tissue fluid, and cartridge and kit for use in the analyzing method are also disclosed.

Description

Technical field: [0001] The present invention relates to a method for collecting tissue fluid containing analyte from a subject, analyzing the analyte contained in the collected tissue fluid, an analysis device for analyzing the analyte contained in the tissue fluid, and an analysis kit used in the analysis method ( Cartridge) and analysis kits. Background technique: [0002] Conventionally, a method capable of collecting interstitial fluid from biological skin and measuring glucose contained in the collected interstitial fluid is known. [0003] The analysis method described in WO95 / 02357 uses a liquid reservoir (reservoir) composed of a double-sided adhesive layer pasted on the patient's skin and a transparent plastic covering layer with holes on the double-sided adhesive layer and measures The unit of measurement of the collected glucose concentration. According to the analysis method described in WO95 / 02357, the liquid reservoir is attached to the patient's skin, and w...
