Magazine for annulary capillary lancets
First Claim
1. Device for receiving a body fluid for analytical purposes comprising a container and at least one sample receiving unit for a single-use test that can be pushed out of a guide chamber of the container by means of a drive unit and to which the body fluid can be applied at a receiving site, wherein the container is designed as a magazine for storing a plurality of sample receiving units and a coupling device to couple the sample receiving unit to the drive unit for a forwards and backwards movement between the guide chamber and the receiving site;
- wherein the sample receiving unit has a free end where the body fluid is drawn into the sample receiving unit;
wherein the sample receiving unit is a test strip; and
wherein the free end of the test strip is flat.

Abstract
A device for receiving a body fluid for analysis, comprising a container and at least one sample-receiving unit which can be impinged upon by the body fluid at a receiving point and which can be extracted from a guide chamber of the container by means of a drive unit. According to the invention, a coupling device is provided in order to couple the sample receiving unit to the drive unit to ensure back and forth movement between the guide chamber and the receiving point.

11. A device for receiving a body fluid for analytical purposes, comprising
a container having a guide chamber; -
a test strip disposed in the guide chamber; a plunger configured to extend into and retract from the guide chamber; a holding claw configured to couple the plunger with the test strip; the guide chamber having a tapered section proximal the holding claw to engage the holding claw in a form fitting manner with the plunger as the plunger extends into the guide chamber; the test strip having a free end where the body fluid is drawn into the test strip, wherein the test strip is configured for use with a separate lancing aid; the guide chamber extending axially between an engagement opening where the plunger is received and a discharge opening; the plunger being moveable from a disengaged position where the plunger is disengaged from the holding claw to a engaged position where the plunger engages the holding claw in the form fitting manner; the test strip being moveable relative to the guide chamber from a retracted position where the free end of the test strip is located inside the guide chamber to an extended position where at least the free end of the test strip extends outside the guide chamber from the discharge opening; and the plunger when in the engaged position being configured to extend the test strip to the extended position and retract the test strip to the retracted position. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A device for receiving a body fluid for analytical purposes, comprising
a container having a guide chamber; -
a test strip disposed in the guide chamber; a plunger configured to extend into and retract from the guide chamber; a holding claw configured to couple the plunger with the test strip; the guide chamber having a tapered section proximal the holding claw to engage the holding claw in a form fitting manner with the plunger as the plunger extends into the guide chamber; a lancet to which the holding claw is secured; and a spring clip coupling the holding claw to the test strip for transferring movement of the plunger to the test strip. - View Dependent Claims (21, 22)

23. A method, comprising:
-
coupling a plunger to a test strip in a guide chamber by advancing the plunger so that a guide block in the guide chamber pushes a holding claw of the test strip to engage the plunger in a form fitting manner, wherein the test strip is configured for use with a separate lancing aid; extending the free end of the test strip from a discharge opening of the guide chamber by advancing the plunger; collecting body fluid with the free end of the test strip; retracting the test strip back into the discharge opening of the guide chamber by retracting the plunger while the holding claw remains engaged to the plunger in the form fitting manner; and decoupling plunger from the holding claw by retracting the plunger so that the holding claw moves to a position where the holding block no longer pushes the holding claw to engage the plunger in the form fitting manner. - View Dependent Claims (24, 25, 27, 28, 29)

26. A method, comprising:
-
coupling a plunger to a test strip in a guide chamber by advancing the plunger so that a guide block in the guide chamber pushes a holding claw of the test strip to engage the plunger in a form fitting manner; extending the test strip from a discharge opening of the guide chamber by advancing the plunger; collecting body fluid with the test strip; retracting the test strip back into the discharge opening of the guide chamber by retracting the plunger while the holding claw remains engaged to the plunger in the form fitting manner; decoupling the plunger from the holding claw by retracting the plunger so that the holding claw moves to a position where the holding block no longer pushes the holding claw to engage the plunger in the form fitting manner; wherein the holding claw is secured to a lancet, wherein a spring clip couples the holding claw to the test strip; during said extending the test strip the spring clip transfers movement of the plunger to the test strip; and puncturing tissue with the lancet by advancing the lancet with the plunger while stopping advancement of the test strip with a wall step in the guide chamber.
