Abstract

The invention relates to a diagnostic device 10 for collecting and analysing a biological sample comprising, an energy source providing means for perforating, ablating and/or altering the stratum corneum of an area of skin from which the biological sample is to be collected; a housing 21 for receiving at least one test strip 22, the test strip being adapted to collect biological sample from the perforated, ablated and/or altered area of skin; and analysing means for conducting diagnostic analysis of the collected sample. The invention also relates to a cartridge 20 containing a plurality of test strips 22 for collecting a biological sample, each test strip comprising an absorbent portion 35 for absorbing the biological sample at an area of skin which has had applied thereto an energy source to perforate, ablate or alter the stratum corneum of the skin, wherein said test strips are adapted to facilitate transmission of the energy source to the skin.

Claims

1. A device, comprising:

a housing;

a laser source mounted in the housing for emitting a laser beam onto the skin of a patient with sufficient energy to enhance the permeability of the skin by perforating, ablating or altering the skin;

capturing media for capturing bodily fluids released through the skin; and

a container mounted on the housing for storing and dispensing the capturing media from therein.

2. The device of claim 1, wherein the container is detachably mounted to the housing.

3. The device of claim 1, wherein the container is a disc rotatably attached to the housing.

4. The device of claim 3, wherein the container comprises one or more openings for dispensing the capturing media.

5. The device of claim 1, wherein the capturing media is absorbent.

6. The device of claim 1, wherein the capturing media is adsorbent.

7. The device of claim 1, wherein the capturing media comprises:

a continuous strip; and

a plurality of capturing portions mounted on the strip for capturing bodily fluids released through the skin.

8. The device of claim 7, wherein each capturing portion comprises a transparent portion for transmitting a substantial portion of the laser beam therethrough.

9. The device of claim 1, wherein the container comprises a plurality of receptacles, each receptacle for storing and dispensing a piece of capturing media from therein.

10. The device of claim 1, comprising:

an analyzer mounted in the housing for analyzing bodily fluids captured by the capturing media.

11. The device of claim 10, wherein the analyzer comprises a glucometer.

12. The device of claim 10, comprising:

an analyzer mounted in the housing for analyzing bodily fluids captured by the capturing media wherein the plurality of capturing media each comprise electronic sensors for interfacing with the analyzer to analyze the retained bodily fluids.

13. The device of claim 1, further comprising:

a detachable casette mounted on the housing; and

test strips within said casette to accept bodily fluids.

14. The device of claim 1, further comprising:

a detachable, rotatable disc comprising a plurality of receptacles, reversibly mounted on the housing; and

a plurality of test strips, each located within a receptacle on the disc to accept bodily fluids.

15. The device of claim 1, further comprising:

a detachable cartridge mounted on the housing; and

a continuous tape of test strips, within the cartridge, spaced on the tape so as to allow each test strip to accept a separate sample of bodily fluids.

16. The device of claim 15, wherein each test strip comprises:

a laser transmitting window; and

an absorbent portion to accept bodily fluids.

17. The device of claim 15, wherein the test strip comprises:

a chamber for the collection of bodily fluids; and

an absorbent portion which is in fluid communication with the chamber.
