Gastric lavage device for rabbit experiments

Abstract

The invention discloses a gastric lavage and gavage device for rabbit experiments, and relates to the field of pharmacological device experiments. The gastric lavage and gavage device for rabbit experiments comprises a fixing device and a liquid guiding device; the fixing device comprises a fixing box, a first opening is formed in the side wall of the left side of the fixing box, a second openingis formed in the left half part of the top wall of the fixing box, a first semicircular hole is formed in the top wall of the fixing box, the liquid guiding device and the top wall of the fixing box are connected, a supporting plate is arranged inside the fixing box, a sliding plate is arranged at the rear part of the supporting plate, a first connecting rod is arranged on the side, away from thesupporting plate, of the sliding plate, a second through hole is formed in the rear wall of the fixing box, one end of the first connecting rod runs through the second through hole to be located outside the fixing box, the bottom of the first connecting rod is fixedly provided with a second connecting rod, and an adjusting device is arranged at the bottom end of the second connecting rod. The device has the advantages that a pipeline can be conveniently inserted into a rabbit body, the pipeline inserted into the rabbit body is controlled, injuries caused to the rabbit body are reduced, and theexperiment efficiency is improved.

Description

technical field [0001] The invention mainly relates to the experimental field of pharmacological devices, in particular to a gastric lavage device for rabbit experiments. Background technique [0002] Rabbits are one of the most commonly used animals in physiology, pharmacology, and toxicology experiments and teaching, and have played an important role in medical and pharmaceutical research. Among them, gastric lavage and gavage of rabbits is a routine operation. In the experimental operation of gastric lavage and gavage of rabbits, it is necessary to fix the rabbits on the box or shelf, tie the legs or body of the rabbits, and then use The gastric lavage tube is used to send medicines or experimental reagents into the stomach of rabbits. This gastric lavage method still has the following problems in practice: [0003] 1. Fixing the rabbit on the box or shelf completely restricts the activity of the rabbit, which will cause fierce resistance of the rabbit, which is easy to ...

AI Technical Summary

Problems solved by technology

[0003] 1. Fixing the rabbit on the box or shelf completely restricts the activity of the rabbit, which will cause fierce resistance of the rabbit, which is easy to cause damage to the rabbit, and it is difficult to insert the gastric feeding tube into the rabbit body smoothly , affecting the experimental process

[0004] 2. In the experiment, human gastric tubes and urinary catheters are often used for operation. The diameter and length of the tubes do not conform to the physiological structure of rabbits, and it is easy to cause damage to the oral cavity, trachea, esophagus and gastric mucosa of rabbits.

[0005] 3. The structure of the existing gavage tube is fixed, the function is single, and due to structural limitations, the experimental procedures of gastric lavage, gavage, and drug addition in rabbits are cumbersome and inefficient
