Mouse inhalation anesthesia induction maintaining device

Abstract

The invention relates to a mouse inhalation anesthesia induction maintaining device, and discloses an induction maintaining device which is characterized in that a transparent box body is filled with anesthetic, then an inner transparent cylinder is opened, the anesthetic uniformly enters the inner transparent cylinder to anesthetize a mouse, and the body position of the mouse can be changed by rotating the inner transparent cylinder so that an experimenter can observe the mouse conveniently. Comprising a medicine buffering assembly, an external anesthesia assembly arranged in the medicine buffering assembly and an internal anesthesia assembly arranged in the external anesthesia assembly, and anesthetic medicine filled in the medicine buffering assembly evenly enters the internal anesthesia assembly through the external anesthesia assembly to anesthetize a mouse. The inner anesthesia assembly and the outer anesthesia assembly rotate synchronously, so that the anesthetized mouse can change the body position, and observation by experimenters is facilitated.

Description

technical field [0001] The invention relates to a mouse inhalation anesthesia induction and maintenance device, relates to an induction and maintenance device used in a mouse inhalation anesthesia experiment, and belongs to the technical field of animal experiments. Background technique [0002] When doing inhalation anesthesia experiments on mice, it is necessary to perform general anesthesia on the mice before observing the expected indicators and vital signs of the mice in the experiment. Most of the existing inhalation anesthesia induction and maintenance devices for mice are composed of a cylindrical single tube and two The wooden plugs at both ends are connected to the anesthesia pump and the recovery box through rubber hoses. This structure has the following problems: 1. When the inhaled general anesthesia drug enters the cylindrical single cylinder, there will be a concentration difference in the cylindrical single cylinder, and the gas It takes a certain amount of t...

Problems solved by technology

[0002] When doing inhalation anesthesia experiments on mice, it is necessary to perform general anesthesia on the mice before observing the expected indicators and vital signs of the mice in the experiment. Most of the existing inhalation anesthesia induction and maintenance devices for mice are composed of a cylindrical single tube and two The wooden plugs at both ends are connected to the anesthesia pump and the recovery box through rubber hoses. This structure has the following problems: 1. When the inhaled general anesthesia drug enters the cylindrical single cylinder, there will be a concentration difference in the cylindrical single cylinder, and the gas It takes a certain amount of time for uniform distribution, and the concentration of general anesthesia drugs inhaled by mice in different positions in the cylindrical monotube is different. Since different mice will move to indeterminate positions after entering the cylindrical monotube, it is impossible to ensure that the anesthesia induction phase enters different mice. The concentration of the anesthetic gas is consistent, which leads to experimental errors; 2. Gas leakage is prone to occur at the connection between the cork and the cylindrical monotube, which leads to experimental errors and endangers the experimenters; 3. The cylindrical monotube is difficult to be in a fixed position and the movement range is difficult to control. Affect the observation of vital signs of mice

[0005] The induction tube and the main tube of the above-mentioned patent for accommodating mice or small mammals are both cylindrical and single-tube structures. The concentration is inconsistent and the cylindrical monotube is difficult to be in a fixed position and the movement range is difficult to control, which affects the observation of the vital signs of mice and other issues
