Abstract

A lancet activating device comprising a housing (3) which houses a reciprocating spring-loaded plunger (17), serving as a trigger to activate a lancet (26); cavity (5,6) for placements of a lancet (26) and a finger (23); apertures (9, 7) for the insertion of said lancet and said finger; leaf-spring (10) to position a finger (23). An unactivated fresh lancet (26) is inserted into the cavity (6) of the lancet activating device and the patient'"'"'s finger (23) is placed into the cavity (5), whereby the finger positioning will be determined by the leaf-spring (10). At a press of the top mounted reciprocating plunger (17), the lancet (26) is activated to puncture the finger (23) and the patient proceeds to withdraw his finger and collection of the micro blood sample can proceed. Thereafter a fresh lancet (26) can be inserted into the cavity (6) of the lancet activating device from the lancet insertion aperture (9). The fresh lancet (26) forces the used lancet (27) out of the lancet activating device via the lancet disposition aperture (8) where it will be transited to an attached container (2) via an access opening (16) located at the top of the container (2). Throughout the procedure, the users of said lancet activating device do not need to come into contact with the patient.

Claims

1. A lancet activating device for comprising:

a. a housing (3) with a cavity (5,6);

b. at least a first aperture (8, 9) on said housing (3) to allow at least one means of lancet access into said cavity (6);

c. at least a second aperture (7) on said housing (3) to allow at least one means of finger access into said cavity (5);

d. means for positioning a finger (23) within said cavity (5) to receive the activation of a lancet (26);

e. an activating means (4) within said housing (3) to activate a lancet (26);

wherein when a lancet (26) is inserted into said lancet access means and a finger (23) is retrievably inserted into said finger access means and said finger (23) is positioned by said finger-positioning means to receive the activation of a lancet (26), said activating means (4) is activated to trigger said lancet (26) to prick said finger (23).

2. A lancet activating device as claimed in claim 1 wherein said lancet access means is perpendicular to said finger access means.

3. A lancet activating device as claimed in claim 1 wherein said activating means (4) comprises of a reciprocating plunger (17).

4. A lancet activating device as claimed in claim 3 wherein said activating means (4) is triggered by mechanical, electrical, electrochemical, hydraulic or pneumatic means.

5. A lancet activating device as claimed in claim 1 wherein said means for positioning a finger comprises at least one leaf-spring (10) mounted onto the housing (3).

6. A lancet activating device as claimed in claim 1 wherein said means for positioning a finger is detachably mounted on said housing (3).

7. A lancet activating device as claimed in claims 5 or 6 wherein said means for positioning a finger can comprise at least a rest pad for said finger (23).

8. A lancet activating device as claimed in claim 1 wherein said means for positioning a finger comprises at least one leaf-spring (10) mounted onto the housing (3) and wherein said means for positioning a finger is detachably mounted on said housing (3) and wherein said means for positioning a finger can comprise at least a rest pad for said finger (23).

9. A lancet activating device as claimed in claim 1 further comprising a stopper (21) to limit the positioning of said finger (23).

10. A lancet activating device as claimed in claim 1 wherein said lancet access means is provided with a pair of grooves (19) to guide the access of a lancet (26).

11. A lancet activating device as claimed in claim 10 wherein said lancet access means is provided with two apertures;

wherein the first aperture (9) is longer than the second aperture (8).

12. A lancet activating device as claimed in claim 11 wherein the longer aperture (9) is located vertically higher on the housing than the smaller aperture (8).

13. A lancet activating device as claimed in claim 12 further comprising at least a means for determining the positioning of a lancet (20).

14. A lancet activating device as claimed in claim 1 wherein said lancet activating device is detachably attached to a container (2) for receiving and storing at least a used lancet (27).

15. A lancet activating device as claimed in claim 1 wherein said lancet activating device is permanently attached to a container (2) for receiving and storing at least a used lancet (27).

16. A lancet activating device as claimed in claims 14 or 15 wherein said container (2) is constructed from any constructible material.

17. A lancet activating device as claimed in claims 14 or 15 wherein said container (2) is constructed from polymeric materials.

18. A lancet activating device as claimed in claims 14 or 15 wherein the container (2) is provided with an opening (16) on the top of the container to receive used lancets (27).

19. A lancet activating device as claimed in claim 16 wherein the container (2) is provided with an opening (16) on the top of the container to receive used lancets (27).

20. A lancet activating device as claimed in claim 17 wherein the container (2) is provided with an opening (16) on the top of the container to receive used lancets (27).

21. A lancet activating device as claimed in claim 18 wherein the container (2) is provided with a lid (14) pivotally mounted on the top of the container (2) to close said opening (16).

22. A lancet activating device as claimed in claim 19 wherein the container (2) is provided with a lid (14) pivotally mounted on the top of the container (2) to close said opening (16).

23. A lancet activating device as claimed in claim 20 wherein the container (2) is provided with a lid (14) pivotally mounted on the top of the container (2) to close said opening (16).
