Title:
ELECTROLYTE ANALYSIS TEST STRIP AND ELECTROLYTE ANALYSIS DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/105944
Kind Code:
A1
Abstract:
An electrolyte analysis test strip (30) according to the present invention comprises: a substrate (31); and electrode layers (43, 44) which include, on one main surface (31a) of the substrate (31), base portions (43a, 44a) provided in specific regions on one-end (31e) side in one direction, and extending portions (43b, 44b) extending from the base portions to the opposite-end (31f) side. Ion selection films (41i, 42i) are provided so as to cover the base portions (43a, 44a). In a plan view in a thickness direction perpendicular to the main surface (31a), the outer circumferential edges of the base portions and the outer circumferential edges of the ion selection films define annular regions (AR1, AR2). The annular regions (AR1, AR2) include water detection materials (47, 48) that are provided so as to be covered with the ion selection films and have a property of undergoing a color change from the original color when brought into contact with water.
