Abstract

Laser medical device produced for incruent determination of glycemie and/or blood's test-tube samples. Are used two sources diode laser from 500 to 1000 nm, with low power ( from 0,01 to 5 W). Out two photonics laser beams are absorbed specifically by glicate haemoglobin and by free plasmatic glucosefor the value of glycemie revealed on the display

Description

Medical laser diode device for incruent determination of glycemie
Laser medical device produced in fixed and/or transportable and/or pocket configuration for bloodless determination of glycemie and/or blood's test-tube samples.
Are used two conventional sources laser or diodes in drugged fibers from 500 to 1000 run., with low power ( from 0,01 to 5 W ) supplied with electricity network or with accumulators, that send Out two photonic laser beams, across nails or skin or on test-tube samples, are absorbed specifically by glicate haemoglobin and by free plasmatic glucose in order to set out the reading of the difference between emitted power and residue power of two photodiodes sensors, and/or CPU, of the value of glycemie revealed on the display.

Claims
