Problems solved by technology

The above marking methods have their own advantages and disadvantages: the dyeing method is simple to operate, but the storage time is short, and it is easy to fade after a long time. The toxic ingredients in the dye will be absorbed by animal sweets and cause toxicity; It causes pain to the animal, and removal of the phalanx can cause movement disorders. In addition, animal ethics have been banned by many institutions. Ear piercing or notching is simple and suitable for small-scale numbering. Multiple piercings on the ears are not in line with animal welfare. It is easy to confuse the number in later observation
[0003] 1. The existing ear tags are all marked with numbers. Due to the limited carrying capacity of mice’s ears, the numbers on the ear tags are small. Animal welfare is considered in the experimental animal room, and the lighting intensity is limited.
It is inconvenient to observe the numbers in subsequent experiments
[0004] 2. The existing ear tag adopts V-shaped metal ear tag, which can complete the fixation of the ear tag clip by pressing and closing. This type of ear tag sheet-shaped puncture tool has a tapered blade structure with a narrow tip and a wide root, which will cause greater damage to the ears of mice. , the blade puncture has a long incision on the ear of the mouse, which is very easy to tear the ear of the mouse, and the incision of this type of blade is not easy to heal, and it is very easy to cause ear infection in the mouse
And there is no buffer safety mechanism in the process of pressing and puncturing the ear tag, which may easily cause the ear of the mouse to be crushed due to excessive force, causing pain to the animal
May also enhance tumor formation
[0005] 3. The existing V-shaped metal ear tags can be fixed by pressing the punching pliers. The existing supporting punching pliers do not have an anti-falling structure, which cannot avoid falling off during the pressing process, and the punching pliers are easy to fall off when the pressing force is excessive. The deformation of the ear tag clip was too tight, which resulted in the extrusion and ulceration around the ear hole of the mouse due to the inability to accurately control the force when the traditional ear tag was punched.
[0006] 4. Most of the existing ear tags use square ear tags, with a plastic layer on the outside, and printed words on the surface of the plastic layer for labeling. However, the existing ear tags make the sheet larger for the convenience of reading, which is difficult for the ears of mice. The load is heavy, and it is easy to tear the punched wound when the mouse is active, thus causing wound infection
Ear tags with large pieces and printed words have a large target, and are easy to be eaten by other mice, resulting in ear tags being damaged or the words are not displayed clearly, which greatly affects the identification of individuals
5. Most of the existing ear tag punching and fixing operations are the operation sequence of first punching and then fixing the ear tag. Not only the operation steps are cumbersome, but also need to pick the ear and assemble and fix it manually at the punching place, which is very inefficient and takes a lot of time.
[0007] 6. The existing ear tag punching and fixing does not perform punching operations for individual batches. After punching and fixing an ear tag, it is necessary to pick the next ear tag to be used, which is very time-consuming and energy-consuming.
[0008] 7. The existing ear tags are observed with the naked eye, check and write the number, and record the experimental results by hand, which cannot realize the intelligentization of experimental data collection

Abstract

The invention relates to the field of animal marking instruments, in particular to a minimally-invasive gap-controllable mouse chip ear tag and a loading device thereof. Punching pliers, a bracket, aguide boss I, a guide boss II, an ejector shaft, a limit disc, a spring I, an ejector pin, a stabilizing block, an ear tag shell, a clamping plate I, ear tag needles, a clamping plate II and an ear tag body are included. According to the minimally-invasive gap-controllable mouse chip ear tag and the loading device thereof, mouse ear punching and ear tag assembling integrated operation is adopted,and the two steps of ear tag punching and ear tag fixing are synchronously carried out. According to the device, the clamping plate I for ear tag needle arrangement and the clamping plate II for ear tag needle arrangement are respectively arranged in the ear tag shell, and multi-station lateral moving type pushing separation is adopted, so that the situation that the ear tag needles need to be independently picked each time to be assembled and fixed to the ear tag body is avoided; and the ear tag needle and the ear tag body in the next group of station can enter a to-be-punched station only bymoving the clamping plates, so that the operation is effectively simplified, the time and labor for picking, pairing and subsequent experimental data acquisition are saved, and the data acquisition intelligence is realized.

Description

technical field [0001] The invention relates to the field of animal marking instruments, in particular to a mouse chip ear tag with minimal invasiveness and controllable gap and a loading device thereof. Background technique [0002] Animal experiments play a vital role in exploring the laws of disease occurrence and development, drug development and vaccine development and other health-related research. Rats are one of the most widely used experimental animals in animal experiments. Labeling animals is the first step in all experimental research. The marking methods of existing experimental animals mainly include body dyeing, toe cutting, ear hole punching or notching, stainless steel earrings, and tattooing. The above-mentioned marking methods have their own advantages and disadvantages: the dyeing method is simple to operate, but the storage time is short, and it is easy to fade after a long time. The toxic ingredients in the dye will be absorbed by animal sweets and cau...
