Abstract

This invention relates to a blood testing apparatus comprising a device for withdrawing blood containing a pricking element, a membrane-type testing means, defining a measuring field, an evaluating device comprising an electronic evaluation system and a display device forming a complete system which can be manipulated as a single piece of apparatus. The aim of the invention is to develop said apparatus in such a way that it is user friendly. The invention is characterized in that a plurality of testing means can be inserted into the apparatus and brought successively to a work position to carry out several measurements wherein said testing means can cooperate together with the evaluating device. The blood withdrawing device also comprises a plurality of pricking elements and each respective testing means is positioned in a work position, wherein a pricking element is pushed through the testing means and pricks the skin surface of the user. The pricking position associated with the work position is disposed in such a position on the device that the blood withdrawn from the surface of the skin can impinge upon the testing means.

Claims

1. A blood testing apparatus, comprising:

a housing;

a disposable configured to be positioned in the housing;

a carrier rotatably positioned in the disposable; and

a plurality of penetrating members and a plurality of sample chambers, each of a sample chamber being associated with a penetrating member to provide for multiple measurements of an analyte from a blood sample, the plurality of penetrating members and plurality of sample chambers being coupled to the carrier.

2. The apparatus of claim 1, wherein the housing, disposable, carrier, plurality of penetrating members and plurality of sample chambers form a single device.

3. The apparatus of claim 1, wherein each of a sample chamber has a volume that does not exceed 1 micro liter.

4. The apparatus of claim 1, further comprising:

A display at an exterior of the housing and configured to display one or more lancing parameters.

5. The apparatus of claim 1, wherein the penetrating members and the sample chambers are arranged on the same carrier that can be handled manually.

6. The apparatus of claim 1, wherein the carrier includes a first carrier part for the sample chambers and a second carrier part for the penetrating members.

7. The apparatus of claim 6, wherein the first and second carrier parts are configured to be assembled to form a manually operable unit.

8. The apparatus of claim 6, wherein the first and second carrier parts are configured to be linked together in a rotationally fixed manner.

9. The apparatus of claim 1, wherein the carrier includes a central recess within which a drive device is provided.

10. The apparatus of claim 1, wherein the carrier is in the form of a ring and is rotatable about a center of the ring.

11. The apparatus of claim 1, further comprising:

a drive device for the carrier that includes internal gearing.

12. The apparatus of claim 1, wherein the penetrating members are arranged on the carrier in such a way that when they are in a launch position, they execute a launch movement in a radial direction with respect to a rotatability of the carrier.

13. The apparatus of claim 1, wherein the penetrating members are arranged on the carrier in such a way that when they are in a launch position they execute a skin penetration movement in an axial direction with respect to a rotatability of the carrier.

14. The apparatus of claim 1, wherein the plurality of penetrating members are surrounded by a sterility barrier on the carrier before execution of a skin penetration event.

15. The apparatus of claim 1, wherein the sample chambers are arranged on the carrier in such a way that they are axially oriented with respect to a rotatability of the carrier.

16. The apparatus of claim 1, wherein at least a portion of the housing has an outside contour that is essentially in the form of a circular disk.
