DEVICE FOR NONINVASIVE MEASUREMENT OF GLUCOSE CONCENTRATION IN BLOOD Russian patent published in 2008 - IPC A61B5/145 G01N33/49 

FIELD: medicine.

SUBSTANCE: device can be used for diagnosing glycemia. Device has detector for registration of informative sign, which detector is connected with autonomous electronic module through receiving-transmitting aids. Module has amplifier connected in series with analog signals to digital code converter, control microprocessor, display, warning signalization tone, interfaces for receiving-transmitting units and for sonic signalization, and electric power source. Device has case with control keyboard, compartment for electric power batteries. Compression cuff for measuring arterial pressure is attached to case mechanically. Pneumatic units are built inside case; units are connected together by flexible hoses. Units have compressor, pressure release valve in cuff, orifice for slow release of pressure. To register information and to converse it to electric signal, pressure transducer is used. Electronic module is made in form of control printed circuit and it additionally has power switches connected with compensator, pressure release valve and microprocessor to perform automatic control of pressure in cuff. Microprocessor has memory unit and for indication of minimal and maximal arterial pressure due to comparison of amplitudes of oscillations of pulse wave. It also has applied program and correlation spreadsheet to calculate content of glucose in blood from relation of parameters of arterial pressure. Noninvasive method of measurement of glucose content in blood is realized in the device. Method provides measurement of systolic and diastolic arterial pressure sequent on both arms, measurement of correlation factor and calculation of glucose concentration on base of correlation spreadsheet, composed on the base of empiric formula of mutual relation of arterial pressure level as well as glucose content in blood. Device is portable and it provides higher safety due to taking analysis without making any damage to patient's skin. Device can be used for individual self-control of patients suffering from diabetes, arterial hypertension and other vascular disorders.

EFFECT: improved reliability; increased precision.
