SOFTWARE COMPLEX FOR REGISTRATION blood pressure and pulse noninvasive method in the conditions of experiments on small rodents

摘要

The invention relates to an experimental medicine and biology, in particular to the research instruments for recording blood pressure and heart rate in the experimental conditions on small rodents. In the present Utility Model Application sensor ripple is embedded in the pinch measuring cuff and formed as a photoelectric detector, consisting of a photosensor and light bulb, and a hardware system to record arterial blood pressure and heart rate non-invasively under the experimental conditions in small rodents additionally introduced adjustable power supply connected fotoelektrocheskogo detector to the lamp, and the electronic control unit, comprising pressure sensor signal amplifier having an input connected to a sensor pRESSURE Nia, normalizing amplifier, whose input is connected to the photosensor, and an analog-digital converter, to the respective inputs of which are connected a pressure sensor amplifier output signal and an output of the normalizing amplifier, output of the analog-digital converter is an output of the electronic unit. The proposed hardware system for recording blood pressure and heart rate non-invasively under the experimental conditions in small rodents, improving the accuracy and reliability of measured parameters, with simultaneous simplification of its structure.
