Abstract

The invention herein described relates to an assessment device comprising an assay part and a detachable recording part. The assessment device facilitates the rapid assaying and processing of tissue/fluid samples by healthcare workers. Also, advantageously, the result of the assay is only apparent to the healthcare worker after interrogation of the recording part at a processing facility.

Claims

1. An assessment device, comprising:

a substrate having an indicated separation line defining first and second portions;

an assay element, arranged on the first portion;

a data recording element, arranged on the second portion; and

means for communicating data from the assay element to the recording element, the data communication means arranged onto the substrate.

2. The assessment device of claim 1, further comprising:

an outer casing comprising a perforated strip in registration with the separation line.

3. The assessment device of claim 1, wherein:

the assay element comprises;

a sample application well; and

a detection zone in fluid communication with the sample well; and

material for assaying a fluid sample, contained in the assay element.

4. The assessment device of claim 3, wherein:

the detection zone comprises means for detecting an assay product.

5. The assessment device of claim 1, wherein:

the means for communicating data from the assay element to the recording element comprises an electrical connection.

6. The assessment device according to claim 1, wherein:

the recording element comprises means for electronic downloading and transfer of data to a processing facility.

7. The assessment device according to claim 1, wherein:

the recording element comprises an electronic storage device.

8. The assessment device according to claim 1, wherein:

the recording element comprises a microchip or microprocessor.

9. The assessment device according to claim 1, further comprising:

an indicator actuated on completion of the assay.

10. The assessment device according to claim 1, wherein:

the assay element comprises a further sample application well, the further sample application well containing a material for assaying a fluid sample.

11. The assessment device according to claim 1, wherein:

the assay element comprises a sample application well, the well comprising a surface impregnated with a material for assaying a fluid sample.

12. An assessment device, comprising:

a substrate having an indicated separation line between first and second portions;

an assay element, arranged on the first portion, comprising;

a sample application well;

a detection zone in fluid communication with the application well; and

material for assaying a fluid sample, contained in the assay element;

a data recording element comprising an electronic storage device, arranged on the second portion; and

an electrical connection between the assay element and the recording element for communicating data from the assay element to the recording element, the electrical connection irreversibly broken when the first and second portions are separated.

13. The assessment device according to claim 12, further comprising:

an indicator actuated on completion of an assay.

14. The assessment device according to claim 12, wherein:

the recording element is provided with data communication control means for electronic downloading and transfer of data to a processing facility.

15. An assessment kit, comprising:

the assessment device according to claim 12; and

protective packaging for transport of the recording element to a processing facility.

16. The assessment device according to claim 12, further comprising an outer casing comprising a perforated strip in registration with the separation line.

17. An assessment device, comprising:

a substrate having first and second portions;

an assay element, arranged on the first portion;

a data recording element, arranged on the second portion;

means for communicating data from the assay element to the recording element, the data communication means arranged onto the substrate; and

a casing having an indicator line defining first and second elements of the casing, such that separating the elements along the indicator line detaches the first and second portions.

18. The assessment device of claim 17, wherein:

separating the elements along the indicator line severs the means for communicating data from the assay element to the recording element.
