A device for animal tail vein injection

Abstract

The invention provides a device for animal tail vein injection, and the device can effectively fix an animal body and facilitate animal tail vein injection. The device comprises a bottom plate and a semi-cylindrical cover body, the sealing end of the cover body is provided with a through hole through which an animal tail can stretch out, and the opening end of the cover body is provided with a piston, wherein the inner diameter of the piston is matched with that of the cover body, and non-slip rubber wraps the edge of the piston; a magnifying lens which is connected to the top of the cover body through a connecting rod and used for magnifying the animal tail is arranged over the through hole, and an auxiliary rod is connected to the connecting rod and provided with a lighting device. The device can be adjusted according to the body size of an experimental animal and is used for fixing the experimental animal without needing to fix the animal tail, and due to the fact that the magnifying lens is installed over the through hole and the lighting device is assembled, the vein of the tail is easier to see clearly; the device is suitable for tail vein injection of various animals with the smaller body size.

Description

technical field [0001] The invention relates to a fixing device for tail vein injection of experimental animals. Background technique [0002] In biological experiments, intravenous injection is usually performed at the tail of the animal. The existing devices fix the tail of the animal so that the body can move. The disadvantages of this device are: first, physical activity will affect the degree of tail fixation. If the fixation is tight, It will affect the speed and amount of drug entry; secondly, if the animal breaks free when the tail is fixed, the tail will be severely damaged, and the intravenous injection cannot be completed, or the animal will be stabbed, and even the experimenter will be bitten by the animal. As the most common animal used in experiments, mice are usually used in experiments because the tail veins of mice are relatively thin, which makes it difficult to inject tail veins in medical experiments. [0003] In view of the above-mentioned defects, the ...

If the fixation is tight, It will affect the speed and amount of drug entry; secondly, if the animal breaks free when the tail is fixed, the tail will be seriously damaged, and the intravenous injection cannot be completed, or the animal will be stabbed, and even the experimenter will be bitten by the animal.

As the most common animal used in experiments, mice are usually used in experiments because the tail veins of mice are relatively thin, which makes it difficult to inject tail veins in medical experiments.
