Abstract

An apparatus comprising a substrate, the substrate having supported thereon:

• • plural collectors each for collecting a bodily fluid from the surface of a body part placed adjacent thereto;
  • an analyser for analysing each collected bodily fluid; and
  • a display for displaying an indication of a result of each analysis.

Claims

1. An apparatus comprising a substrate, the substrate having supported thereon:

plural collectors each for collecting a bodily fluid from the surface of a body part placed adjacent thereto;

at least two pairs of electrodes integral with each of the collectors;

an analyzer for analyzing each collected bodily fluid, wherein the analyzer comprises a controller, wherein each of the at least two pairs of electrodes are connected to the analyzer and wherein the analyzer is configured to analyze at least one electrical signal received via a first pair of the at least two pairs of electrodes; and

a display for displaying an indication of a result of each analysis, wherein the apparatus is configured to activate the analyzer in response to a predetermined electrical signal received via a second pair of the at least two pairs of electrodes, and

wherein the controller comprises memory having stored thereon software instructions that, if executed by the controller,

cause the controller to activate the display in response to a predetermined electrical signal received via a third pair of the at least two pairs of electrodes integral with each collector.

2. An apparatus according to claim 1, wherein a bodily fluid collecting end of each of the collectors is covered by a removable seal.

3. An apparatus according to claim 2, wherein each removable seal provides a fluid impermeable barrier around the bodily fluid collecting end of the respective collector.

4. An apparatus according to claim 1, wherein each second pair of electrodes is located closer to a bodily fluid collecting end of the respective collector than each first pair of electrodes.

5. An apparatus according to claim 1, wherein each third pair of electrodes is located further from a bodily fluid collecting end of each collector than each first pair of electrodes.

6. An apparatus according to claim 1, wherein the apparatus further comprises an adjustable calibration resistor.

7. An apparatus according to claim 1, wherein the substrate is disc shaped and the plural collectors are arranged generally radially on the substrate.

8. An apparatus according to claim 1, wherein the apparatus comprises a cover plate and a glue layer disposed between the substrate and the cover plate, wherein the glue layer is structured so as to define a maximum extent of each of the collectors.

9. An apparatus according to claim 8, wherein the cover plate has a plurality of notches in an outer edge of the cover plate, each notch being aligned with a respective collector.

10. A method for analysing a bodily fluid sample, comprising:

a bodily fluid analysis device receiving a bodily fluid sample at one of a plurality of bodily fluid collectors formed therewith;

the bodily fluid analysis device detecting a predetermined electrical signal received via a second pair of at least two pairs of electrodes integral with each bodily fluid collector;

in response to detecting the predetermined signal via the second pair of electrodes, activating a controller and analyzing the collected bodily fluid sample using the controller by analysing at least one electrical signal received via a first pair of the at least two pairs of electrodes;

the bodily fluid analysis device detecting a predetermined electrical signal received via a third pair of at least two pairs of electrodes integral with each bodily fluid collector;

in response to detecting the predetermined signal via the third pair of electrodes, activating a display of the bodily fluid analysis device; and

the bodily fluid analysis device displaying an indication of a result of the analysis.
