Abstract

An apparatus for eliciting a blood sample comprises a housing, an aperture in a wall of the housing, an aperture cover moveable between a first position in which the aperture is covered and a second position in which the aperture is uncovered, the aperture cover comprising a sealing member configured to seal the aperture on a first side of the wall when the aperture cover is in the first position and a user-contactable part extending from the sealing member through the aperture to the second side of the wall and configured to allow a user to move the aperture cover between the first and second positions.

Claims

1-13. -13. (canceled)

14. 1. An apparatus for eliciting a blood sample comprising:

a housing;

an aperture in a wall of the housing;

an aperture cover moveable between a first position in which the aperture is covered and a second position in which the aperture is uncovered, the aperture cover comprising a sealing member configured to seal the aperture on a first side of the wall when the aperture cover is in the first position and a user-contactable part extending from the sealing member through the aperture to the second side of the wall and configured to allow a user to move the aperture cover between the first and second positions.

15. The apparatus of claim 14, wherein the user-contactable part comprises a covering part configured to cover the entire aperture from the second side of the wall, when the aperture cover is in the first position.

16. The apparatus of claim 15, wherein the aperture cover is configured so as to slidably receive a portion of the wall between the sealing member and the covering part when the aperture cover is moved between the first and second positions.

17. The apparatus of claim 15, comprising a biasing member configured to bias the aperture cover towards the first position, wherein the biasing member is located between the sealing member and the covering part of the aperture cover.

18. The apparatus of claim 14, wherein the apparatus comprises a guide member for constraining the movement of the aperture cover to a predefined path.

19. The apparatus of claim 14, comprising a biasing member configured to bias the aperture cover towards the first position.

20. The apparatus of claim 19, wherein the aperture cover comprises a first catch member and the housing comprises a second, corresponding catch member and wherein the first and second catch members engage one another when the aperture cover is moved to the second position, thereby to retain the aperture cover in the second position.

21. The apparatus of claim 20, wherein the second catch member is depressible, and wherein the first and second catch members are configured to disengage from one another when the second catch member is depressed.

22. The apparatus of claim 21, wherein the apparatus is configured to perform a plurality blood sample elicitations and to cause the second catch member to be depressed each time a blood sample has been elicited.

23. The apparatus of claim 22, comprising a plurality of test disc members, each used for a single blood sample elicitation, the test disc members each including a protruding portion, wherein after one of the test disc members has been used to elicit a blood sample, the protrusion is moved into contact with the second catch member thereby depressing the second catch member and allowing the aperture cover to return to the first position.

24. The apparatus of claim 23, wherein the second catch member comprises a protruding portion with which the protrusion of the test disc member comes into contact to depress the second catch member.

25. The apparatus of claim 14, wherein the apparatus comprises a test disc member used for a single blood sample elicitation, the test disc member being configured so as to apply pressure on the sealing member when the aperture cover is in the first position, thereby to improve the sealing of the aperture by the sealing member.

26. The apparatus of claim 14, wherein the aperture cover is configured to slide between the first and second positions.
