Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water bath cooling experiment equipment, in particular to a circulating water bath cooling experiment equipment. BACKGROUND

[0002] In various biological experiments, rats are generally used. Rats are the first experimental animals used in nutritional research and have made outstanding contributions to human research. As an experimental animal, rats have the following advantages: moderate size, fast reproduction, high litter size, easy feeding, convenient drug administration, appropriate and easy sampling, low teratogenicity, and diverse behaviors, and are widely used in experimental research. The existing device for rat water bath ensures the cleanliness of the rat and helps the cultivation of the rat.

[0003] The existing water bath device is provided with a device for fixing the head of the rat, which is generally two mutually close pressing plates (such as two half-arc plates). During the process of combining the two pressing plates into a circle, the moving neck of the rat is easy to contact the end of the pressing plate due to the instinct struggle. When the corresponding ends of the two pressing plates are combined, the moving rat's skin is easy to be pressed, causing damage to the rat.

[0004] Therefore, we propose a circulating water bath cooling experiment equipment. SUMMARY
