Protection device for monkey self-administration pre-embedded pipeline

Abstract

The invention relates to equipment for medical experiments, in particular to a protection device for a monkey self-administration pre-embedded pipeline. A monkey wears wearable equipment. The protection device for the pre-embedded pipeline comprises a protection box fixed to the wearable equipment, a liquid passing pipe connected to the protection box and a protection pipe arranged outside the liquid passing pipe; and one end of the protection pipe is fixedly connected to the protection box, and the other end is rotatably connected to a side plate of a cage where the monkey is located. According to the application, the connection stability of the liquid passing pipe and the liquid medicine passing smoothness are improved, and the problem of liquid leakage or pipeline blockage is reduced.

Description

technical field [0001] The present application relates to a medical experiment equipment, in particular to a protection device for a pre-embedded pipeline for self-administration of monkeys. Background technique [0002] Self-administration is an operational behavioral experiment, which uses the drug reinforcement effect to change the behavior of animals before and after exposure to drugs, and is the most direct method to study the mechanism of drug addiction and evaluate the anti-addiction efficacy of drugs. It is the model with the most test validity that simulates the whole process of addiction to the greatest extent. Non-human primates (such as monkeys) are the closest to humans in terms of kinship, and are highly similar to humans in terms of physiology, anatomy, and behavior; their longer life cycle is also more suitable for long-term drug addiction research, It can better simulate the pathological process of human addiction and relapse, and has an irreplaceable impor...

Problems solved by technology

[0005] In view of the related technologies mentioned above, the inventor found that: during the experiment, the monkey moved in the cage and drove the universal valve to rotate to release the generated torque. , It is easy to cause damage to the valve of the universal valve. If the valve is damaged, it will easily lead to the problem of liquid leakage. On the one hand, it will cause errors in the amount of liquid injected into the animal body, and on the other hand, it will cause corrosion at the connection position of the universal valve. It hinders its rotation, causing the problem that the liquid pipe is twisted and blocked during the animal's activities
