Biotechnical INFORMATION MEASURING SYSTEM FOR RESEARCH antidiuretic activity body fluids

摘要

FIELD: medicine.;SUBSTANCE: information-measuring biotechnical system of physiologic-medical purpose for analysis of antidiuretic activity of liquid media of experimental animal represents construction, whose technical part contains scales for experimental animal, reservoir for solution, cannulas for introduction into jugular vein and animal's urine bladder, metering device, amplifier and recorder. It additionally contains calibrating unit of urine drop breaking, photometric sensor, binary-decimal counter and decoder, electronic scales with timer, pump-metering device is made in one unit with reservoir, fixed on animal body. Recorder is electronic with 4-digit LCD indicator. Volume of each drop of hypotonic solution fed into animal jugular vein, is set by preliminary regulation of duration of control pulse, commuting feeding bus of pump-metering device for the time of said pulse action.;EFFECT: increase of accuracy and reliability of analysis.;1 dwg
