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 (26)

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.
