Abstract

A blood testing apparatus has a test member and a laser source configured to produce a wound from which blood flows. The laser source produces at least a cutting wavelength, and a coagulation wavelength. Electronics for analysis and a display are provided. The test member, laser source, electronics and display form a glucose monitoring system that is integrated in a single apparatus.

Claims

1. A blood testing apparatus, comprising:

a laser source configured to produce a wound from which blood flows, the laser source producing at least a cutting wavelength, and a coagulation wavelength, the laser source including an IR blocking filter reflects a portion of the laser beam towards a photodiode such that the photodiode is adapted for detecting the laser beam from the IR blocking filter as a feedback for controlling a power output of the optical resonant cavity;

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 laser source is a single diode laser source.

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

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

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

6. The apparatus of claim 1, further comprising:

a carrier positionable in a housing, the housing including a locating device for positioning of the carrier; and

a plurality of test members positioned in the carrier.

7. A blood testing apparatus, comprising:

a plurality of test members at a cassette, each of a test member positioned in a recess in a circumferential wall section in a concentric arrangement around a rotation of axis of the cassette;

a laser source configured to produce a wound from which blood flows, the laser source producing at least a cutting wavelength, and a coagulation wavelength;

one or more humidity covers positioned at at least a portion of the test members, the one or more humidity covers the humidity cover being at least partially removable;

a feedback for controlling a power output of an optical resonant cavity of the laser;

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, wherein the plurality of test members, laser source, electronics and display form a glucose monitoring system that is integrated in a single apparatus.

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 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 the laser source is a single diode laser source.

10. The apparatus of claim 7, wherein the laser source is a first diode laser and a second diode laser.

11. The apparatus of claim 7, wherein the first wavelength is 532 nm and the second wavelength is 1064 nm.

12. The apparatus of claim 7, further comprising:

a carrier positionable in a housing, the housing including a locating device for positioning of the carrier, the plurality of test members being positioned in the carrier.
