Problems solved by technology

[0003] The vascular perfusion devices on the market are not effective in immobilizing animals. When the animals are infused with medicinal liquid, it is difficult to fix the animals quickly, and during the fixation process, the animals are prone to scratch and bite the staff due to pain, causing staff injuries

Abstract

The invention discloses a blood vessel perfusion device based on animal medical experiments, and relates to the technical field of medical experiments, the blood vessel perfusion device comprises a pedestal, a fixing ring seat and a needle head assembly, a workbench is arranged on the outer side of the top of the pedestal, and transposition assemblies are connected to the two sides of the top of the workbench. A motor on the inner side of a transverse rod works, a steering seat can drive a fixing ring seat to rotate by 180 degrees, air is continuously blown to the inner side of a first air bag, the first air bag can extrude the chest of an experimental animal, temporary insufficient blood and oxygen supply in the experimental animal can be caused, the movement flexibility of the experimental animal can be reduced, and the experimental animal can be more conveniently taken out. Meanwhile, the experimental animal stands upside down and is restrained to move, the experimental animal can enter a forced quiet state, the situation that workers are hurt due to the fact that the workers are bitten by the animal due to pain when a needle head is inserted into the animal body can be greatly reduced by enabling the experimental animal to be quiet quickly, meanwhile, the experimental animal is quiet quickly, and the working efficiency is improved. The perfusion blood vessel can be conveniently found.

Description

technical field [0001] The invention relates to the technical field of medical experiments, in particular to a blood vessel perfusion device based on animal medical experiments. Background technique [0002] Animal experiments refer to scientific research using animals in laboratories to obtain new knowledge about biology, medicine, etc. or to solve specific problems. Animal experiments must be conducted by trained personnel with research degrees or professional technical capabilities Or under its guidance, in animal medical experiments, it is often necessary to infuse drugs into the blood vessels of animals to test the effects of drugs and the effects of drugs on the body and the body's response to the drugs. [0003] The vascular perfusion devices on the market are not effective in immobilizing animals. When the animals are infused with medicinal liquid, it is difficult to fix the animals quickly, and during the fixation process, the animals are prone to scratching and bit...
