COMPUTERIZED DEVICE FOR DETERMINING ELECTROMAMMOGRAPHIC POTENTIAL IN CARRYING OUT MASS SCREENING OF MAMMARY GLANDS Russian patent published in 2005 - IPC

FIELD: medical engineering.

SUBSTANCE: device has power supply source, two electrodes, in series connected analog-to-digital converter, micro-processor, optronic decoupling unit, radio modem and computer as well as keyboard and indicator unit connected to the micro-processor. Seven controllable keys, two decoders, amplifier and two filters are additionally introduced into design. The first electrode output is connected to inputs of the first and the fourth key, the second electrode output is connected to inputs of the second and the fifth key, outputs of the fourth and the fifth key and input of the third key are connected to ground. Outputs of the first, the second and the third key are connected to amplifier input which output is connected to the sixth and the seventh key inputs. The sixth key output is connected to the first input of analog-to-digital converter via the first filter. Output of the seventh key is connected to the second input of analog-to-digital converter via the second filter. The first microprocessor output is connected to control input of the sixth key; the second microprocessor output is connected to control input of the seventh key. The third microprocessor output is connected to output of the first decoder. The fourth microprocessor output is connected to input of the second decoder the first and the second outputs of which are connected to control inputs of the fourth and the fifth key, respectively. The second and the third outputs of the first decoder are connected to control inputs of the first, the second and the third key.

EFFECT: high accuracy and reliability of examination results.
