DISPOSABLE INDICATOR COMPONENT FOR MEASURING CONCENTRATION OF ANALYTE IN BIOLOGICAL FLUIDS Russian patent published in 2024 - IPC A61B5/20 A61B5/145 A61B5/103 

FIELD: medical equipment.

SUBSTANCE: disposable indicator component for use in a system for measuring concentration of an analyte in a biological fluid comprises an indicator zone, comprising at least one colorimetric element for measuring the analyte, a connector for connecting the indicator component to the component having at least one spectrophotometer placed inside the housing, a liquid transport layer in liquid communication with the indicator zone, an upper plate holding the plate. Layer of the first flexible web is adjacent to the liquid transport layer. Liquid-impermeable shell surrounds the indicator zone adjacent to the liquid transport layer. Layer of the second flexible web is adjacent to the liquid-impermeable shell. Fasteners are located on the layer of the second flexible web. First flexible web layer, fluid transport layer, liquid-impermeable shell and layer of the second flexible web are superimposed on each other in order and fixed between the upper plate and the retaining plate. Indicator zone contains at least two colorimetric elements for measuring the analyte. Liquid-impermeable shell has a discrete pocket, arranged and configured to contain each of at least two colorimetric elements of analyte measurement, and wherein each pocket has a unique opening in fluid communication with the liquid transport layer. Liquid transport layer is arranged and configured to inhibit liquid transport between the holes in the liquid impermeable shell. Alternative version of the disposable indicator component is disclosed.

EFFECT: high accuracy of measurement results.
