Multifunctional liquid-spraying dosing combination device for part of laboratory animal

The invention belongs to the technical field of scientific experimental apparatuses, and in particular to a multifunctional liquid-spraying dosing combination device for a part of a laboratory animal. The combination device comprises a liquid-moving device and a mouse fixing device. The combination device is characterized in that in the liquid-moving device, the head of a micro-quantitative liquid-moving plastic tube is provided with a metal nut interface, an independent isochoric double-hole plastic hose is connected with the metal nut interface through a metal sealed two-way valve, a plastic liquid-spraying head gasket is arranged in a double-blade ear-shaped plastic liquid-spraying head, the double-blade ear-shaped plastic liquid-spraying head is connected with the independent isochoric double-hole plastic hose, the double-blade ear-shaped plastic liquid-spraying head and the independent isochoric double-hole plastic hose are in accordance with the ear shape of a mouse, uniform liquid spraying can be realized, the assembling of the mouse fixing device is simple, the head of the mouse can be well fixed, a plurality of mice can be simultaneously fixed, an operator can understand the state of the mice in time through a transparent shell, and a metal deformable buckle is easy to operate and has a fixing effect. According to the combination device, the problem of inaccurate experimental data due to non-uniform medicine application to the mice can be effectively solved.
