Device for assaying analytes in bodily fluids

Abstract

A device for determining the presence and/or quantity of one or more analytes in a sample of human body fluid has a container for receiving a sample of body fluid, with an interior that is delimited by a base and by a circumferential surface. It further comprises at least one test strip and a holding element for receiving and holding the one or more test strips. The holding element is designed such that it has a shape corresponding and adapted to the peripheral circumferential surface of the container. The device further comprises an elongate sampling element having an absorbent sampler that takes up the sample of body fluid and by means of which the sample of body fluid is transferred into the container. Further, the base of the container has a central elevation via which the sample of body fluid can be conveyed from the sampler, by compression thereof on the elevation, to the at least one test strip.

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This application is a continuation of copending International Patent Application PCT / EP 2010 / 000948 filed on Feb. 16, 2010, and designating the US, which international Patent Application has been published in German language as WO 2010 / 091897, and claims priority from German Patent Application DE 10 2009 010 563.8 filed on Feb. 16, 2009. The entire contents of these priority applications are incorporated herein by this reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to a device for determining the presence and / or quantity of one or more analytes in a sample of human body fluid, comprising a container for receiving a sample of body fluid, and further comprising at least one test strip with an absorbent section and with reagents for determining the presence and / or quantity of one or more analytes in the sample.[0003]More specifically, the present invention concerns a device for collecting and testing a liquid sampl...

Benefits of technology

[0048]In another preferred embodiment, the holding element is at least partially bonded to the container, in particular to the inner face of the circumferential surface and/or of the base. Like the abovementioned clamp fit, the bonding of the holding element to the container can prevent slipping of the holding element and thus prevent contamination of the sample.

[0049]It will be appreciated that this bonding can also be used in combination with the clamp fit, thus additionally improving the connection between holding element and container.

[0050]As an alternative to this, it is possible for the holding element to be fitted through a guide means arranged on the base of the container. A guide means on the base of the container has the advantage that the holding element can be inserted more easily and thus more quickly into the container during production.

[0051]Moreover, in a preferred refinement, the holding element has recesses in which the test strips are respectively arranged. The recesses allow the test strips to be fitted in place and prevent slipping of the test strips inside the holding eleme

Problems solved by technology

Another disadvantage of the tests known from the prior art is that, for an initial detection of the drugs, sufficient quantities, i.e., relatively large quantities, of body fluids are needed in order to allow the tests to be carried out.
