Anesthetic measuring device

Abstract

The invention discloses an anesthetic measuring device, and belongs to the technical field of anesthetic measurement.The anesthetic measuring device is characterized by comprising a transparent box and at least three transparent cases, the transparent cases are distributed in the transparent box at equal intervals, measuring cases are arranged in the transparent cases in a sliding fit manner, A tail clamping mechanism used for fixing the tail of a small animal is arranged on the front surface of each measuring case, an extrusion module is arranged on one side of each measuring case, an arc-shaped opening is formed in one side of each transparent case, at least two gas conveying pipelines are arranged on one side of the transparent box, the gas conveying pipelines are connected to an external gas supply end and extend into the transparent box, at least three gas distribution pipelines are arranged at the lower end of each gas conveying pipeline. The anesthetic measuring device can reduce the placement difficulty of animal tails, meanwhile, the concentration in each cavity can be controlled according to actual needs, and the control process is also relatively simple.

Description

technical field [0001] The invention relates to the technical field of anesthetic agent measurement, and more specifically, relates to an anesthetic agent measurement device. Background technique [0002] In the field of animal research in anesthesiology, routine anesthesia experiments often involve measuring the sensitivity of small animals to inhalational anesthetics, which can be used to study the sensitivity of small animals with certain gene mutations to existing inhalational anesthetics to determine The target of inhaled anesthetics can also be used to study the anesthesia effect of new anesthetics on small animals. In order to determine the application dose of small animals to inhaled anesthetics, it is necessary to determine the effective dose range or dose-effect curve of the inhaled anesthetics, which specifically involves two test experiments: 1. Determination of the inhalation ability of small animals that cannot maintain the righting reflex In the experiment of...

Problems solved by technology

[0003] In the prior art, to carry out the above two test experiments, a closed induction box with a volume greater than or equal to 5L is generally used to measure the small animals one by one. Two large holes are provided on the closed induction box to facilitate the insertion of small animals in the box. And for human hands to reach in and operate, each large hole is fitted with a movable cover to seal or open. However, the operation of reaching out will cause the gaseous state in the closed induction box to escape and communicate with the external gaseous state, resulting in a decrease in the anesthetic gaseous concentration. In order to ensure the gaseous concentration of the anesthesia, the movable cover is generally closed immediately after the hand-reaching operation is completed to seal the seal, and the gaseous anesthetic drug with a flow rate of up to 4L / min is continuously introduced to balance the concentration in the box to the set concentration, and the drug concentration in the induction box reaches It takes 20 minutes to equilibrate, because this method consumes a lot of gaseous anesthetics due to the large volume of the closed induction box; in addition, since a single experiment is only for a single small animal, it takes Experiment with at least 30 small animals

In summary, the existing closed induction box has the disadvantages of long experiment time, waste of gaseous anesthetics, and low work efficiency.

[0004] In response to the above problems, some small animal tails have been placed outside the induction box to avoid reaching out and facilitate observation. However, in the actual operation process, it is more difficult to place the small animal tail inside the small through hole. Difficult, which increases the difficulty of the operation, and although there is a box that separates multiple chambers, the concentration of the drug entering the gas still cannot be controlled separately, resulting in the same gas entering each chamber, which is not conducive to different drugs. Concentrations are compared
