METHOD AND RADIOTRANSMITTING SENSOR FOR CONTROL OF HUMAN BIOPHYSICAL PARAMETRES Russian patent published in 2010 - IPC A61B5/04 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment, namely to devices for control of patient's biophysical parametres. Device contains two sensors of blood flow pulse waves, made in form of high-frequency LC contours, one of which in switched into frequency-setting circuit of autogenerator with controlled electric power supply, the second being connected to demodulator inlet. Radiotransmitting sensor also contains microprocessor with memory device, commutator, switched into the circuit of electric power supply to autogenerator, and outlet for connecting outer control-diagnosing equipment. Method of parametre control lies in the following: radiotransmitting sensor is applied onto part of patient's body with close blood flow location, for instance ear lobe, operations of control of pulse wave parametres, converting these parametres into digital codes and microprocessor processing of digital codes are carried out. After that results of processing are transmitted to outer control-diagnosing equipment. Control of pulse wave parametres is carried out by control of electromagnetic parametres of high-frequency resonator, which consists of two LC contours.

EFFECT: application of invention allows to ensure complex control of patient's biochemical parametres by means of one multi-parametre sensor with radio transmission of control results to control-diagnosing equipment, to increase sensitivity of measurements and reliability of obtained results.
