| 成果简介 | NOVELTY - The device has a pressure chamber for creating compression and decompression and measuring optical density of a vessel. An electric compressor is connected with an amplifier with voltage. An LED indicator of an output signal level is arranged at an output to visualize operation of photo sensors. A device body is powered by a voltage converter from plus 5 volt to minus 5 Volt on a special microcircuit through which an electrical signal passes depending on pulse strength with fixation by an optical sensor with a different throughput system of elements of circuits with a current resistance for about 0.15 Ohm and 0.1 Ohm. A bipolar power source of the circuit is used on a special chip. A circuit for determining optical density with a transmission coefficient is connected with the device body that is connected to a laptop through or linear audio input to record the signal using a special analytical personal computer program. USE - Device for measuring venous pressure. |
