Abstract

Apparatus for detecting presence of a blood sample is presented where the apparatus comprises a housing having an aperture, the aperture configured to receive a body part of a user, a camera having a field of view that encompasses at least a portion of the aperture, the camera configured to capture images of the user'"'"'s body part, and a processor. The processor is configured to control operation of the camera receive the captured images, and determine whether a predetermined quantity of blood is present on the surface of the user'"'"'s body part.

Claims

1-15. -15. (canceled)

16. Apparatus for detecting presence of a blood sample, the apparatus comprising:

a housing having an aperture, the aperture configured to receive a body part of a user;

a camera having a field of view that encompasses at least a portion of the aperture, the camera configured to capture images of the user'"'"'s body part; and

a processor configured to;

control operation of the camera;

receive the captured images; and

determine whether a predetermined quantity of blood is present on the surface of the user'"'"'s body part,

characterized in that the processor is configured to analyse the captured images to monitor a position of the lancet.

17. Apparatus according to claim 16, wherein indicators are provided on the lancet.

18. Apparatus according to claim 16, wherein the camera is mounted on or within the housing.

19. Apparatus according to claim 16, wherein the housing is configured to retain a cartridge containing at least one testing member.

20. Apparatus according to claim 17, wherein the camera is mounted on or within the cartridge.

21. Apparatus according to claim 19, wherein each of the at least one testing members is rotatably mounted on a shaft and comprises a blood collection part located at a first position at the edge of the member.

22. Apparatus according to claim 21, wherein the processor is further configured, in response to a positive determination that a predetermined quantity of blood is present on the surface of the user'"'"'s body part, to control the apparatus to present the blood collection part of a first one of the at least one testing members to the aperture.

23. Apparatus according to claim 19, wherein each of the at least one testing members are movable along the cartridge such that different ones of the testing members are able to be presented at the aperture in turn.

24. Apparatus according to claim 19, wherein the processor is further configured to analyse the captured images to detect a position of the user'"'"'s body part.

25. Apparatus according to claim 24, wherein each of the at least one testing members comprises a lancet protruding from a second position at an edge of the member

26. Apparatus according to claim 25, wherein the processor is further configured, in response to a detection that the user'"'"'s body part is within a range of predetermined positions, to control the apparatus to advance the lancet of a first one of the at least one testing members into the aperture, thereby to lance the user'"'"'s body part.

27. Apparatus according to claim 16, the apparatus further comprising a light source configured to illuminate the user'"'"'s body part.

28. Apparatus according to claim 16, wherein the processor is further configured to analyse the captured images to measure a property of the blood sample.

29. Apparatus according to claim 16, wherein the aperture is configured such that a portion of the body part of the user enters the aperture.

30. A method of detecting presence of a blood sample, the method comprising:

providing a housing having an aperture, the aperture configured to receive a body part of a user;

providing a camera having a field of view that encompasses at least a portion of the aperture, the camera configured to capture images of the user'"'"'s body part; and

providing a processor configured to;

control operation of the camera;

receive the captured images; and

determine whether a predetermined quantity of blood is present on the surface of the user'"'"'s body part,

characterized in that the processor is configured to analyse the captured images to monitor a position of the lancet.
