Abstract

The invention relates to a device for storing and supplying lancets for obtaining bodily fluids, the device comprising a lancet magazine having a lancet storage unit for a plurality of needle-shaped lancets and a drive unit for carrying out a piercing process of a lancet, and there being a retraction unit which moves the lancet back from the piercing position to the rest position thereof after the piercing process is carried out.

Claims

1. A device for storing and supplying lancets for obtaining bodily fluids, comprising:

a lancet magazine, which comprises a lancet storage unit, having a plurality of substantially needle-shaped lancets, and a drive unit, which moves a selected lancet for carrying out a piercing process from a rest position into a piercing position in a piercing direction, and

a retraction unit, which moves the selected lancet from the piercing position into the rest position thereof after the piercing process has been carried out, the retraction unit being connected to the lancet storage unit and being displaceable with respect thereto, and the drive unit being fixed with respect to the retraction unit along the piercing direction.

2. The device according to claim 1, wherein the lancet storage unit, which is substantially a cylindrical shell form and in which the plurality of substantially needle-shaped lancets are arranged distributed mutually parallel on a circular path, encloses the retraction unit, which is substantially cylindrical in form, at least in part, the retraction unit being displaceable inside the lancet storage unit.

3. The device according to claim 1, wherein the drive unit comprises at least one plunger-like element, a plunger end of which touches an end of the selected lancet during the piercing process and displaces the selected lancet in the piercing direction inside the lancet storage unit.

4. The device according to claim 3, wherein the plunger-like element is suitable for displacing the retraction unit with respect to the lancet storage unit.

5. The device according to claim 1, wherein each substantially needle-shaped lancet is arranged inside the lancet storage unit, which is in the form of a cylindrical shell, in a continuous duct.

6. The device according to claim 2, wherein the plurality of substantially needle-shaped lancets each have a curved end so as each to engage in a depression, extending in a radial direction, on an end surface of the at least partially cylindrical retraction unit.

7. The device according to claim 1, comprising a first clip connection which connects the drive unit in the form of a plunger-like element to the retraction unit rigidly as seen in the piercing direction.

8. The device according to claim 7, wherein the first clip connection is suitable for twisting the plunger-like element with respect to the retraction unit about a longitudinal axis, extending in the piercing direction, of the lancet magazine.

9. The device according to claim 7, comprising a second clip connection, which holds the retraction unit in a particular displacement position with respect to the lancet storage unit if all of the plurality of substantially needle-shaped lancets are in a rest position.

10. The device according to claim 7, wherein the drive unit is loaded with spring force by means of at least one spring element, so as to move the plunger-like element and the retraction unit along the piercing direction.
