An inhalation anesthesia device for experimental animals

Abstract

The present invention relates to the technical field of experimental animal inhalation anesthesia equipment, in particular to an inhalation anesthesia device for experimental animals, comprising a bottom plate, a rectangular parallelepiped glass cover is fixedly connected to the top surface of the bottom plate, and a rectangular parallelepiped glass cover is provided on the top surface of the rectangular parallelepiped glass cover A special-shaped notch, the inner wall of the special-shaped notch is embedded and fixed with an inhalation anesthesia module, the inhalation anesthesia module includes an air delivery mechanism, the air delivery mechanism includes an air delivery tube, and one end of the air delivery tube is fixedly connected to an air outlet, A plurality of air outlet holes are opened on the inner wall of one end of the air outlet. In the present invention, by rotating the outer wall of the rotating column, both the air outlet and the air inlet are communicated with the air hole inside the cylinder cavity, and the wind from the outside entering the cylinder cavity through the air inlet will pass through the air outlet together with the ether gas. Reaching the air outlet, the inhalational anesthesia replenishment for experimental mice is realized, and the work efficiency and safety of the inhalational anesthesia replenishment work are improved.

[0002] In some surgical experiments on animals, in order to reduce the animal's struggle and keep the animals quiet and easy to operate, the experimental animals are often given necessary anesthesia. Although experimental animal anesthesia is one of the commonly used methods in medical experiments, it is necessary to realize the Accurate anesthesia has always been one of the most difficult problems for researchers. The traditional anesthesia for experimental animals is mainly to inject anesthetics through muscle, abdominal cavity or vein. Oxygen and anesthesia are difficult to maintain and other problems. If the experiment time is too long, it is necessary to continuously add anesthetic drugs, and the dose is difficult to control accurately. In addition, injection anesthesia generally wakes up slowly, and the existing method of inhalation anesthesia for experimental mice is to inject volatile The anesthetic ether sponge and the experimental animals were placed in a glass cover. After the animals were anesthetized, the animals were taken out for experiments. The experiment took a little longer, and the animals were easy to wake up. Anesthesia supplementation was required, that is, the experimental mice were placed in the ether sponge again. In the glass cover, the anesthesia replenishment process is time-consuming and laborious, which affects the experimental operation, and the ether anesthetic itself is flammable. This kind of operation is very unsafe. In addition, ether smells bad, pollutes the laboratory environment, and is also harmful to the experimenter. Therefore, it is necessary to control the ether Supplementary dosage of inhalational anesthesia, but some experimental mouse inhalational anesthesia devices do not have the ability to adjust the supplementary dosage of ether anesthesia
