Experimental rat labelling device and labelling method

Abstract

The invention relates to an experimental rat labelling device and a labelling method, and belongs to the field of animal labelling. The device comprises an injection pipe, a magnifying glass and an injection needle, wherein the injection pipe is V-shaped, and is composed of an injection arm and a holding arm, an injection head is installed at the top end of the injection arm, a pigment injection pipe is arranged on the injection arm, the pigment injection pipe communicates with the injection arm, and the tail end of the pigment injection pipe is plugged by an elastic plug. The method for conducting labelling by means of the device is further provided. The method for conducting labelling by means of the device comprises the steps of numbering toes on the two front paws of a rat as front numbers, numbering toes on the two rear paws of the rat as rear numbers, and numbering the whole rat as a double-digit number, wherein the front number is the number in the tens of the double-digit number, and the rear number is the number in the ones of the double-digit number. According to the device and the method, color will never fade, and multiple animals can be labelled.

Description

technical field [0001] The invention belongs to the field of animal marking, and in particular relates to an experimental mouse marking device and a marking method. Background technique [0002] In the process of drug research and development, rats and mice are often used for drug safety testing. Usually, the amount of animals used is relatively large, and several animals will be placed in one cage, so the identification of animals is particularly important. [0003] There are roughly several types of small animal marking devices on the market: the first is a marker pen. The specific method of use is to write directly on the tail of a small animal with a marker pen, but the mark fades easily. Basically, it takes 2-3 It will be relabeled every day, which is error-prone. The second is to use a tattoo machine to tattoo numbers on the tails of small animals. This kind of tattoo is not easy to fade, but it is very troublesome to operate and the efficiency is very low. The third...

[0003] There are roughly several types of small animal marking devices on the market: the first is a marker pen. The specific method of use is to write directly on the tail of a small animal with a marker pen, but the mark fades easily. Basically, it takes 2-3 It will be relabeled every day, it is easy to make mistakes

The second is to use a tattoo machine to tattoo numbers on the tails of small animals. This kind of tattoo is not easy to fade, but it is very troublesome to operate and the efficiency is very low.

The third is the dyeing agent, which is directly dyed on the animal hair. This method is easy to operate and not easy to fade, but the number of animals marked is very limited

The fourth is to cut toe marks. This method is only suitable for young mice. It will cause pain for adult mice and does not meet animal welfare requirements.
