The invention relates to a rat and mouse pelma pain threshold detector. The rat and mouse pelma pain threshold detector comprises a fixing support, a shell and a controller. A fixing plate is arranged at the top of the fixing support. A fixing groove is formed in the fixing plate. A fixing net is installed in the fixing groove. A transparent rat / mouse box is arranged on the fixing plate. A base plate is arranged at the lower portion of the fixing support, and the shell is installed on the base plate. A telescoping mechanism is installed at the bottom of the shell. A needle base is installed at the upper end of the telescoping mechanism, and a needle is installed on the needle base. A connecting plate is horizontally arranged in the shell. A laser positioning instrument and a camera are installed on the connecting plate. The connecting plate is provided with holes matching the needle correspondingly. A sliding plate is installed at the bottom end of the shell, a handle is fixedly installed on the sliding plate, and a button is arranged on the handle. The rat and mouse pelma pain threshold detector has the beneficial effects that the needle can be controlled by the controller to upwards stimulate the pelma of a rat or mouse, and the rat or mouse breaks away from the needle after feeling pains; and comprehensive and accurate results are obtained through the controller according to the length of the length of time the needle stays in the bodies of the animals and the pressure applied by the bodies of the animals to the needle, and mistakes possibly caused by using a macroscopic observation method are avoided.
Description
technical field [0001] The invention relates to an animal detection instrument, in particular to a plantar tenderness instrument for rats and rats. Background technique [0002] Before new analgesic drugs are used clinically, they must be tested or verified by animal experiments, especially experiments in mice. Therefore, the sting test analysis of rats and mice has very important practical significance. It can accurately evaluate the efficacy of new drugs by observing the behavioral ability, motor function and sensory ability of rats and mice after medication. In the sting test, the sting analysis of the needle on rats and mice is an important step to carry out. Most of the existing tests on animal stings directly observe the sensitivity of animals to stinging reactions with naked eyes, and there is no relevant equipment to make a detailed and comprehensive analysis of animal stinging reactions, so it is difficult to draw accurate conclusions.
