Small animal anesthesia experiment box with fixing device

Abstract

The invention discloses a small animal anesthesia experiment box with a fixing device. The small animal anesthesia experiment box comprises an anesthesia box, an air-oxygen mixed gas tank and an anesthetic volatilization tank, an anesthesia port is formed in the side wall of the anesthesia box, a positioning tube and a fixing platform are arranged on the anesthesia port, the positioning tube comprises a bearing bottom plate and a plurality of surrounding plates, a fixing port is formed in the bearing bottom plate, two side walls of the bearing bottom plate are a first side wall and a second side wall, each surrounding plate and the adjacent surrounding plate are in hinged arrangement to form an arc-shaped cover, one side of each arc-shaped cover is hinged to the first side wall while the other side of the same is fixedly connected and combined with the second side wall to form a positioning pipe, one end of each positioning pipe is detachably connected with the anesthesia port while the other end of the same is provided with a propelling port, each propelling port is provided with a propelling rod in an inserted manner, and a pushing plate is arranged at the end of each propellingrod and is in clearance fit with the corresponding positioning pipe. The small animal anesthesia experiment box is simple in structure and can effectively anesthetize small animals; animal bodies canbe exposed outside the anesthesia box, so that convenience is brought to an experimenter to conduct a stress experiment on an experiment target.

Description

technical field [0001] The invention relates to the technical field of animal experiments, in particular to a fixing device for inhalation anesthesia experiments on small animals. Background technique [0002] In the experiment of studying the effects of long-term (>0.5h) exposure of inhaled anesthetics on rats / mice, the problem of exposure devices must be involved. Keep the animal breathing spontaneously and avoid intubation or tracheotomy for mechanical ventilation. At present, the animal is anesthetized mainly by placing the small animal directly in a transparent airtight anesthesia box, and then injecting anesthesia gas. This anesthesia method can ensure that the animal is anesthetized spontaneously, but it is difficult for the experimenter to effectively anesthetize the animal. Verify whether the anesthesia is complete. If the degree of anesthesia is too deep, it will also easily lead to inaccurate experimental data, and even lead to the direct death of the animal. ...

At present, the animal is anesthetized mainly by placing the small animal directly in a transparent airtight anesthesia box, and then injecting anesthesia gas. This anesthesia method can ensure that the animal is anesthetized spontaneously, but it is difficult for the experimenter to effectively anesthetize the animal. Verify whether the anesthesia is complete. If the degree of anesthesia is too deep, it will also easily lead to inaccurate experimental data, and even lead to the direct death of the animal. The airtight anesthesia box is also difficult for the user to detect the stress response of the animal during the anesthesia process. It is necessary to open the box This detection method is very cumbersome, if the anesthesia is not in place, it is necessary to close the box again, and then inject the anesthetic gas to ensure the concentration of the anesthetic agent, and open the box for detection, the anesthetic gas in the box will also leak out , may affect the experimenter and affect the efficiency of the experiment

By anesthetizing a small animal such as the head into the anesthesia room, the animal usually struggles violently. In order to avoid struggling, the limbs of the animal need to be fixed. good anesthesia
