Device for assaying analytes in bodily fluids
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. The sampling element can include an indicator strip for determining whether the amount of liquid sample sufficient for carrying out an assay.
1. A device for determining the presence of one or more analytes in a sample of human body fluid, comprising:
a container for receiving a sample of body fluid, with an interior that is delimited by a base and by a circumferential surface having an inner face;
at least one test strip including an absorbent section and reagents for determining a presence of one or more analytes in the sample of body fluid;
a holding element for receiving and holding the one or more test strips, said holding element having a shape corresponding to at least a portion of the circumferential surface of the container, the holding element positioned at the at least a portion of the circumferential surface and bearing upon an inner face of the circumferential surface and holding the at least one test strip;
an elongate sampling element including an insertion element and an absorbent sampler at a first end of the insertion element, the absorbent sampler being insertable into the container for transfer of the sample of body fluid into the container,
wherein at least one of the insertion element and the absorbent sampler includes an indicator for indication of the presence of the liquid sample sufficient for determining the presence one or more analytes in the sample.
2. The device of claim 1 , wherein the test strip is configured to determine an amount of the one or more analytes.
3. The device of claim 1 , wherein the indicator comprises a strip of an absorbent material present in the sampling element.
4. The device of claim 3 , wherein the indicator is configured as an indicator strip.
5. The device according to claim 3 , wherein the sampling element has a marking for indicating minimum travelling distance of the sample of body fluid through the indicator strip.
6. The device of claim 1 , wherein the holding element is shaped with pretensioning and clamped into the container.
7. The device of claim 1 , wherein the holding element is at least partially bonded to the circumferential surface on the inside of at least one of the container and the base.
8. The device of claim 1 wherein the holding element extends entirely around the circumferential surface.
9. The device of claim 1 wherein the container is transparent and has a planar surface, and the holding element has a portion corresponding to the planar surface and has a plurality of vertical recesses each with a plurality of test strips therein, and the test strips are positioned and visible through the holding element at the planar surface.
10. A device for determining the presence of one or more analytes in a sample of human body fluid, comprising:
a container for receiving a sample of body fluid, with an interior that is delimited by a base and by an inner circumferential surface, the container having a pair of opposing planar sides;
a plurality of test strips, each including an absorbent section and reagents for determining a presence of one or more analytes in the sample of body fluid;
a holding element for receiving and holding the plurality of test strips, said holding element having a shape corresponding to the inner circumferential surface of the container, the holding element having a pair of sides with vertical recesses therein, each side positioned at one of the opposing planar sides, the plurality of recesses receiving and holding the plurality of test strips; and
an elongate sampling element including an insertion element and an absorbent sampler at a first end of the insertion element, the absorbent sampler being insertable into the container for transfer of the sample of body fluid into the container;
wherein the insertion element includes an indicator for indication of the presence of the liquid sample sufficient for determining the presence of analytes in the sample.
11. The device of claim 10 for determining the presence of one or more analytes in a sample of human body fluid, wherein the holding element is a single unitary piece that extends entirely around the inner circumferential surface.
