Description

Technical Field

[0002] Animal experiments refer to scientific research conducted in laboratories using animals in order to gain new knowledge about biology, medicine, etc. or to solve specific problems. In order to reduce the struggle of experimental animals, keep them quiet, and facilitate experimental operations, experimental animals are usually anesthetized. The traditional method is mainly to anesthetize experimental animals by directly injecting anesthetics such as xylazine, pentobarbital, chloral hydrate, etc. into the peritoneum. However, due to individual differences in animals, this method has problems such as long anesthesia induction time and different durations. It is not conducive to animal awakening and can easily cause respiratory depression and a decrease in body temperature, heart rate, and blood pressure, thereby affecting the physiological functions and test results of experimental animals. When performing animal anesthesia, Western developed countries usually use gas inhalation anesthesia technology, which can quickly anesthetize and awaken animals, and it is easy to control the depth of anesthesia during operation, and it is safe.

[0003] The applicant has found that the prior art has at least the following technical problems: the existing inhalation anesthesia operation mostly uses containers such as beakers and specimen cylinders, which are filled with cotton medicine to make a simple anesthesia device. Although this method is easy to operate, it has the problems of slow evaporation of anesthetics and inability to stably control the intensity and depth of anesthesia, and is poor in practicality.
