High-efficiency mouse tail vein injection device

Abstract

The invention discloses a high-efficiency mouse tail vein injection device. The high-efficiency mouse tail vein injection device comprises supporting legs, a fixing plate and a fixing chamber which are sequentially connected, wherein the fixing chamber adopts a cavity-shaped structure of which the front end is open and the back end is closed; a first slit is formed in the fixing chamber; a second slit communicated with the first slit is formed in the back end surface of the fixing chamber; an accommodating groove communicated with the second slit is formed in the fixing plate; an electric heating device and a light-transmittable lamp are arranged inside the accommodating groove; a baffle plate is movably arranged inside the fixing chamber; the baffle plate is connected with a holding rod; a plurality of breathable holes are formed in the baffle plate; a limiting column is connected into the first slit in a threaded manner; through holes are formed in corresponding positions of the bottom of the fixing chamber and the fixing plate; a plurality of cross rods are arranged inside the through holes; a collecting box in inserted connection with the bottom of the fixing plate is arranged at the bottoms of the through holes; a fixing mechanism is arranged on the fixing plate. The high-efficiency mouse tail vein injection device integrates fixing, heating and light-transmittable observation, can improve the accuracy of distinguishment and injection, improves the working efficiency, reduces harm to a mouse, is energy-saving, high in efficiency, easy to learn and operate, low in error rate, and low in energy consumption.

Description

technical field [0001] The invention belongs to the technical field of medical experiment equipment, and in particular relates to a high-efficiency mouse tail vein injection device. Background technique [0002] Because the gene sequence of mice is very similar to that of humans, it is widely used in experiments and inspections on the safety, toxicity, and efficacy of food, cosmetics, pharmaceuticals, biological products, industrial products, or medicine and life sciences; in experiments or inspections In the process of growing up, rats will be injected with certain drugs or other liquids. Among them, the tail injection of rats is the most common; because the tail veins of mice are relatively thin, it is difficult to inject tail veins in medical experiments. Traditional methods The mouse is caught by the experimenter so that the tail of the mouse cannot swing during the injection, but this method will cause the experimenter to be bitten by the mouse, etc. At the same time, t...

[0002] Because the gene sequence of mice is very similar to that of humans, it is widely used in experiments and inspections on the safety, toxicity, and efficacy of food, cosmetics, pharmaceuticals, biological products, industrial products, or medicine and life sciences; in experiments or inspections In the process of growing up, rats will be injected with certain drugs or other liquids. Among them, the tail injection of rats is the most common; because the tail veins of mice are relatively thin, it is difficult to inject tail veins in medical experiments. Traditional methods The mouse is caught by the experimenter so that the tail of the mouse cannot swing during the injection, but this method will cause the experimenter to be bitten by the mouse, etc. At the same time, the existing mouse holder cannot match the size required for the experiment. If the mice are completely matched, it is impossible to ensure that all the experimental mice are fully fixed, which makes the mice not fixed firmly, causing the mice to struggle and their tails to slip, resulting in the failure of the experimental operation; or the mice are fixed too tightly in the experiment, resulting in the death of the mice in the experiment , can not guarantee the smooth progress of follow-up experiments, because the tail vein injection of mice is difficult, especially for colored mice (black or brown-black), the tail vein blood vessels are thin and difficult to identify, usually by wiping alcohol or soaking in warm water to dilate the blood vessels, Infrared lamps are also used for irradiation, but the operation is cumbersome and difficult, and an experimental device that integrates fixation, heating, and light-transmitting observation is needed to ensure the safety of the experimenters and the stability of the mice to ensure subsequent experiments. In order to improve the scientific nature of the experiment, in view of the above technical problems, it needs to be improved
