Abstract

A blood testing apparatus includes a laser source configured to produce a wound from which blood flows and at least one test member. A humidity cover is positioned at the at least one test member. The humidity cover is at least partially removable. Electronics are provided for analysis. The electronics includes an evaluation device for comparisons with previously stored measurements or evaluation data with the evaluation device storing a current test measurement.

Claims

1. A blood testing apparatus, comprising:

a laser source configured to produce a wound from which blood flows;

at least one test member;

a humidity cover positioned at the at least one test member, the humidity cover being at least partially removable;

electronics used for analysis, the electronics further including an evaluation device that provides for comparisons with previously stored measurements or evaluation data with the evaluation device storing a current test measurement; and

a display.

2. The apparatus of claim 1, wherein the test member includes an opening from which a beam from the laser can pass through.

3. The apparatus of claim 1, wherein the laser source is a single diode laser source.

4. The apparatus of claim 1, wherein the laser source is a first diode laser and a second diode laser.

5. The apparatus of claim 1, wherein the first wavelength is 532 nm and the second wavelength is 1064 nm.

6. The apparatus of claim 1, wherein the laser source includes a first and a second laser.

7. A blood testing apparatus, comprising:

a laser source configured to produce a wound from which blood flows;

a plurality of test members;

one or more humidity covers positioned to cover the plurality of test member, the one or more humidity covers being at least partially removable;

electronics used for analysis, the electronics including an evaluation device that provides for comparisons with previously stored measurements or evaluation data with the evaluation device storing a current test measurement; and

a display.

8. The apparatus of claim 7, wherein the plurality of test members are arranged radially around an axis of rotation of a rotatable, disposable device having a circumferential wall section that runs cylindrically on an outer periphery, each of the test member and the at least one lancing element having a longitudinal axis that is substantially perpendicular relative to the axis of rotation, and wherein the test members are disposed with surfaces normal in a radial direction with respect to a center of the rotatable, disposable device

9. The apparatus of claim 7, wherein each of a test member includes an opening from which a beam from the laser can pass through.

10. The apparatus of claim 7, wherein the laser source is a single diode laser source.
