DIODE LASER DEVICE FOR THE NON-INVASIVE MEASUREMENT OF GLYCAEMIA

摘要

The device is built using two diode laser sources, with a conventional or with a drugged fibre source, fed either through the electric system in case the device is in its fixed form or by (rechargeable) batteries for the portable, pocket-size device. The two laser sources involved are in a range between 500 and 1000 nm, with a power in the range between 0,01 to 100 mW. The rays are conveyed through an optical condenser and, starting up a key, they are emitted either on a nail or on the skin or even on a free blood sample. A photodiodic sensor or a CPU read the energy subtracted by glycate haemoglobin and free plasmic glucose. This value is converted into the immediate glycaemia value and appears on the device display.
