Acousto-optical-electric programmable random stimulator

Abstract

The invention belongs to the technical field of experimental devices, relates to an experiment device for preparing an experimental animal model, in particular to an acousto-optical-electric programmable random stimulator, which consists of a singlechip, a display screen, an input keyboard, a voltage sampling unit, a voltage regulating transformer, an electric shock control unit, an acousto-optical control unit, an electric shock mouse cage and acousto-optical equipment, wherein the singlechip is connected with the display screen, the input keyboard, the voltage sampling unit, a motor control power supply and the acousto-optical control unit respectively; an external power supply is used for supplying power to the voltage sampling unit and the motor control power supply through the voltage regulating transformer; the motor control power supply is connected with the electric shock mouse cage; the acousto-optical control unit is connected with the acousto-optical equipment. As is proved by a using result, due to the adoption of the acousto-optical-electric programmable random stimulator, the learning and memorizing processes of the experimental animal model can be hindered, the formation of conditioned reflex is delayed, and the modeling efficiency is effectively increased; the stimulator can be applied to preparation of stress-induced hypertension animal models.

Description

technical field [0001] The invention belongs to the technical field of experimental devices, and relates to an experimental device for preparing experimental animal models, in particular to an acoustic, optical and electrical programmable random stimulator, which can be used for preparing stress-induced hypertension animal models. Background technique [0002] Animal experimentation is an indispensable means and method for scientific research in the fields of biomedicine and pharmacy, especially in pharmacology, physiology, neurobiology, zoology and other disciplines. Experimental animals are a necessary condition for exploring life phenomena and their essence, and are an important basis and supporting condition for life science research. With the help of indirect research on animal models, factors that are impossible or difficult to exclude under natural conditions can be consciously changed. In order to more accurately observe the experimental results of the model and cond...

Problems solved by technology

[0004] Most of the devices used in the prior art to prepare animal models of hypertension use the method of plantar electric shocks with fixed time intervals combined with noise stimulation. There are following defects in the described method: often appear conditioned reflexes in the modeled animals to reduce their stress. Extensive degree, prolonging the modeling time, reducing the efficiency of modeling and other defects, so as to affect the accuracy of experimental research results
