Mouse Tail Docked Blood Collector

Abstract

The invention relates to the technical field of animal blood collection equipment, and specifically discloses a tail-docking blood collection device for mice. The invention includes a latex cover, a detachable glass tube, a tapered groove, a suction hole, a vacuum surrounding wall, an exhaust hole, a bottom regulator, and a through hole; the invention mainly uses the principle of vacuum to extract air from the bottle, so that Negative pressure is formed inside the bottle, and the blood will flow out quickly under the action of negative pressure, so as to collect a large number of blood samples from mice; the blood sampler is equipped with a vacuum surrounding the wall to prevent air leakage from causing the blood to spray backwards. The bottom adjuster can adjust the height of the bottom of the blood collection device according to the length of different tails. The blood collection device of the present invention is easy to use and saves working time.

Description

technical field [0001] The invention relates to the technical field of animal blood collection equipment, in particular to a tail-docked blood collection device for mice. Background technique [0002] Products developed in modern laboratories need to use some experimental animals to evaluate their safety performance, and mice are one of these experimental animals, which are low in cost and strong in sensitivity, and are conducive to quantitative comparisons. Many security experiments. Most of these animal experiments are based on collecting blood samples for monitoring. [0003] The existing blood collection methods for mice are basically divided into four types: the first one, eye socket blood collection, that is, use a capillary to penetrate the mouse eye socket; the second one, tail blood collection, that is, use scissors to cut the tail of the mouse for blood collection; , decapitated blood collection; fourth, jugular vein blood collection. [0004] The first kind of ...

AI Technical Summary

Problems solved by technology

[0004] The first kind of orbital blood collection has more blood than the tail blood collection, but improper operation can easily blind the mice; the second tail blood collection can be used for multiple blood collections, but the blood collection time is longer and the blood volume is less

The third type of decapitated blood collection has the largest blood collection volume, but it is not conducive to multiple blood collection

The fourth type of jugular vein blood collection requires very high requirements for operators, and it is not easy for ordinary experimenters to master

[0005] For the second tail blood collection, the existing tail-docking blood collection method has the disadvantages of long blood collection time and low blood collection volume

[0006] Using the existing tail-docking blood collection, because the individual mice are relatively small, the blood vessels are relatively thin, and there is not much blood. If the blood collector needs to collect 200 microliters of blood samples, it will be more difficult, so it is necessary to pat and rub the tail of the mice in advance. Knead to make the blood vessels in the tail of the mice swell, and the collector uses a centrifuge tube to catch the blood samples dripping from the tail of the mice. next blood sample collection

During the blood collection process, the mouse's tail sometimes swayed due to pain, and it was difficult to accurately catch the dripping blood
