An optical-electronic device for determination of peripheral blood filling contains a sensor, which consists of irradiation source and three photodetectors, three amplifiers, calculator, which consists of microcontroller, block of galvanic separation, serial interface and personal computer. The outlet of calculator microcontroller is connected through the block of galvanic separation and serial interface with input of the personal computer the outlet of which is connected through the serial interface and block of galvanic separation with the microcontroller input. An optical outlet of the personal computer is the outlet of optical-electronic device, which contains five photodetectors, nine optical fibers, five amplifiers, block of forming of standards and block of standards. The outlet of the first, second, third, fourth, fifth, sixth, seventh and eighth photodetectors is connected with the first input of, correspondingly, first, second, third, fourth, fifth, sixth, seventh and eighth amplifiers. The second input of it is connected with the first outlet of calculator microcontroller. The outlets are connected to the corresponding inputs of calculator microcontroller. The second outlet of it is connected with the input of block of standard forming, the outlet of which is connected with the first input of block of standards, the outlet of which is connected with the input of calculator microcontroller, the third outlet of which is connected with the second input of block of standards. |
