Abstract
The present invention is directed to a device that extends the reach of a test strip, and to an analytical method that provides for assembly and use of the device. The inventive device is based on a combination of a test strip and test strip packaging that enables the reach of a test strip to be extended.
Claims18
A device for extending the reach of a test strip, comprising
- in an unassembled state, a test strip comprising an elongated support comprising a handle end and at least one reagent-bearing absorptive matrix attached to an opposing end of the support, and
- a test strip package wherein said test strip is removably contained within said test strip package, and the reagent-bearing end of said support is disposed within an end of said test strip package opposite an end that is devised to be opened for removability of said test strip from said test strip package by said handle end of said support, and wherein an exterior surface of said test strip package comprises an adhesive area, and
- in an assembled state, when said test strip package is opened and said test strip is removed from said test strip package, comprising said handle end of said support adhered to the exterior surface of the opened test strip package by pressured contact with said adhesive area.
An analytical method
- that utilizes a test strip comprising an elongated support that comprises a handle end and at least one reagent-bearing absorptive matrix attached to an opposing end of the support, and a test strip package within which said test strip is removably contained, wherein said test strip package comprises an end devised to be opened for removal of said test strip, and the reagent-bearing end of said support is disposed within an end of said test strip package opposite the end to be opened, and an exterior surface of said test strip package comprises an adhesive area;
- said analytical method being beneficial for analysis of a fluid contained within an enclosure comprising an opening through which said test strip may be extended, and comprising
- opening said test strip package,
- removing said test strip from the opened end of said test strip package without touch-contact with said at least one absorptive matrix, by use of said handle end of said support,
- extending the reach of said test strip wherein said handle end of said support is assembled to the opened test strip package by pressure contact of said handle end with said adhesive area and unintended contact with said at least one absorptive matrix is minimized,
- extending the reagent end of the reach-extended test strip through the enclosure opening whereby contact with the fluid is made by said at least one absorptive matrix, and
- withdrawing said test strip from contact with the fluid and thereafter evaluating the developed color on said test strip.
