Blood collection device for experimental mouse

Abstract

The invention relates to a blood collection device for an experimental mouse. The blood collection device comprises an operation panel, the operation panel is provided with a groove with an upward opening, the operation panel is provided with a clamping groove located at one end of the groove, an anesthesia tube is placed in the clamping groove, a constraint plate is disposed above the operation panel, the side portion of the constraint plate is rotatably connected with the operation panel, the side portion of the constraint plate is detachably connected with the operation panel, the constraint plate is provided with a through hole towards the groove, a cavity is disposed in the constraint plate, and a shear mechanism is disposed in the cavity and can extend into the through hole from thecavity. The shear mechanism is connected with an operating mechanism, the operation panel is fixedly connected with a vertical rod, the top end of the vertical rod is rotatably connected with a horizontal plate, the horizontal plate is fixedly connected with a vertical fixing rod and provided with a cylinder, a piston chamber detachably connected with the fixing rod is disposed below the horizontal plate, a piston is slidably connected in the piston chamber, and a piston rod is fixedly connected between the piston and the cylinder. The scheme facilitates mouse heart blood collection by one person, and the operation is convenient and simple.

Description

technical field [0001] The invention relates to the field of laboratory equipment, in particular to a blood collection device for experimental mice. Background technique [0002] In medical research, people often use mice to make disease models, to observe the kinetics of drug metabolism in animals or to study and evaluate the effect of a certain treatment method. According to statistics, more than half of the scientific research topics in medical biology are completed with rodents. Rats are the most numerous experimental animals in medical research, and how to draw blood samples has become one of the most basic and important pre-procedure steps in scientific research. [0003] At present, there are three main methods of blood collection in mice, namely, tail tip blood collection, orbital blood collection and heart blood collection. Among them, the so-called heart blood extraction refers to cutting the skin 2.0-2.5 cm from the middle of the mouse's chest, so that the ribs ...

AI Technical Summary

Problems solved by technology

The above-mentioned operation methods are all done manually, so the operation is relatively cumbersome. When the operator pulls up the fur with his hands or stretches the cut part of the chest, the operator cannot release his hands to prepare for other operation steps, which brings troubles to the operator. It is inconvenient to come, or multiple people are required to cooperate to complete the blood collection of mice, thus wasting manpower
