Description

Quick batch anchoring device for light minimally invasive mouse ear tags

Technical Field

The invention relates to the field of animal marking instruments, in particular to a light minimally invasive quick batch anchoring device for mouse ear tags.

Background

Animal experiments play a vital role in exploring the rules of disease occurrence and development, drug research and development, vaccine research and development and other health-related researches, and mice are one of the experimental animals with the largest dosage and the widest application in animal experiments. Animal labelling is the first step in all experimental studies. The existing marking method of the experimental animal mainly comprises a body dyeing method, a toe cutting method, an earhole punching or mouth cutting method, a stainless steel earring and a body tattooing method.

The marking method has the advantages and disadvantages: the dyeing method is simple to operate, but has shorter storage time, is easy to fade after long time, and toxic components contained in the dye can be absorbed by animal desserts to cause toxicity; the toe cutting method is simple to operate and long in duration, can cause pain of animals, can cause movement disorder due to phalangeal removal, and is forbidden by a plurality of mechanisms in addition to animal ethics; the ear hole punching or cutting method is simple to operate, is suitable for small-scale numbering, and multiple holes punched on ears do not accord with animal welfare, and the numbering is easily confused by later observation. The cut preservation time is not long and is easy to be damaged by other mice, and the marked information quantity is less; stainless steel metal earrings are low in cost and easy to operate, and have the disadvantages of possible shedding, infection, enhancement of tumor formation and pain of animals. The ear tag method is simple to operate and long in storage time, and the marked information amount is far more than that of other marking methods. Therefore, the mouse ear is generally and commonly marked by adopting an ear tag method, however, in actual operation, the existing ear tag has the following defects to be solved urgently:

1. The existing earmark punching and fixing do not perform punching operation on batch individuals, and after one earmark is punched and fixed, the next earmark to be used needs to be picked, so that time and energy are very consumed.

2. The current ear tag adopts V type metal ear tag, presses the closure and can accomplish the fixation of ear tag clamp, and this kind of ear tag slice puncture cutter is sharp end narrow, the wide toper blade structure of root, and is great to the injury of mouse ear, and the blade puncture is longer to mouse ear incision length, very causes the mouse ear to tear easily, and this kind of blade incision is difficult for healing, causes the mouse ear to appear infecting the condition very easily. And there is no buffering safety mechanism in the process of pressing and puncturing the ear tag, so that the mice and the ears are easy to be crushed due to excessive force, thereby causing pain of animals and possibly enhancing tumor formation.

3. The current V type metal ear tag can press the ear tag that punches fixedly through the pincers that punch, and current supporting pincers that punch does not have anti-drop structure, can't avoid pressing down the in-process and drop, and should punch pincers and press the ear tag clamp and press out the deformation too tight condition in pressing force excessive easy appearance, the mouse ear punches around when leading to traditional ear tag to punch because the condition that the dynamics can't be accurately mastered leads to the extrusion ulcer appears.

4. The prior ear tag punching and fixing operation is mostly performed by firstly punching and then fixing the ear tag, so that the operation steps are troublesome, and the ear tag is manually assembled and fixed at the punching position, so that the efficiency is quite low, and a large amount of time is consumed.
