A blood collection device for mice with tail docking

Abstract

The invention provides a tail-docked blood collection device for mice, which belongs to the technical field of experimental equipment. It solves the problem of less blood collection in the existing mouse tail-docking blood collection. The mouse tail blood collection device includes a base and a mouse chamber. The tail of the mouse chamber has a mouse tail protruding opening. The outside of the mouse chamber is provided with a connecting pipe. The two ends of the connecting pipe are connected. The side wall of the mouse barn has a hollow interlayer, and a water bath tube is provided inside the connecting pipe. The side wall of the water bath tube has a water bath interlayer. One end of the water bath interlayer is connected to the above-mentioned hollow interlayer, and the other end of the water bath tube is connected to a twisting mechanism. The water bath tube is made of flexible material, and the water bath tube can be twisted under the control of the twisting mechanism. The mouse tail blood collection device can use a water bath tube filled with warm water to wrap and heat the mouse tail during the blood collection process, so as not to wet the mouse tail, keep the blood vessels full, and improve the blood collection efficiency.

Description

technical field [0001] The invention belongs to the technical field of experimental equipment, and relates to a tail-docked blood collection device for mice. Background technique [0002] Because the gene sequence of mice is similar to that of humans, some medical research and clinical experiments are done by mice. During the whole experiment process, it is often necessary to collect blood from the mice several times. The more common blood collection methods are basically divided into 4 types: the first one, the orbital blood collection, that is, using a capillary to penetrate the mouse’s eye socket; the second one, the tail blood collection , which is to cut the tail of the mouse with scissors to collect blood; the third method is to decapitate the mouse; the fourth method is to collect blood from the jugular vein. [0003] 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 ...

AI Technical Summary

Problems solved by technology

[0003] 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

[0004] For the second tail blood collection, the existing tail-docking blood collection method has the disadvantages of long blood collection time and small blood collection volume, so before blood collection, the mouse tail blood vessels must be filled, and the method used is generally hot water heating. Soak the tail of the mouse in hot water. After the mouse is fixed, this operation is very inconvenient. After the tail of the mouse is taken out, the tail of the mouse needs to be wiped clean. During the wiping process, the tail of the mouse will become cold again, and the effect is average.
