Embodiment 1

[0042] Such as figure 1 and figure 2 A mouse tail vein blood collection system shown includes a table body 1. The table body 1 includes a horizontal plane 101 and an inclined plane 102. A centrifugal device 2 is arranged on the horizontal plane 101. A rat body fixing assembly, Mouse tail positioning device 3, mouse tail clamping assembly, the mouse tail positioning device 3 includes a passage 4 for the mouse tail to pass through; also includes a bearing platform 5 on the inclined plane 102, the upper surface of the bearing platform 5 is parallel to the horizontal plane 101, and An insertion hole 6 for placing an EP tube is opened on the upper surface of the platform 5 .

[0043] Wherein, the mouse body fixing assembly includes several arc-shaped stoppers 7, a semi-conical cylinder 8 between the arc-shaped limiters 7 and the mouse tail positioning device 3, and the height and width of the internal passage of the semi-conical cylinder 8 are all along the The inclined directio...

Embodiment 2

[0046] Such as Figure 1 to Figure 4 A mouse tail vein blood collection system shown, on the basis of Embodiment 1, the mouse tail clamping assembly includes the first slide rail 12 arranged on the inclined plane 102, two slide rails 12 that are slidably fitted on the first slide rail 12 One clamping rod 13, the axis of the first slide rail 12 is parallel to the horizontal plane 101; any one clamping rod 13 is connected to the first driving member 14 on the side away from the direction where the other clamping rod 13 is located, and the first driving The member 14 is used to drive the connected clamping rod 13 to move linearly along the first slide rail 12 . The surface of one side of any clamping rod 13 facing the direction of the other clamping rod 13 is a concave arc surface. The top of one of the clamping rods 13 is connected to the mounting part 15, and the mounting part 15 extends toward the direction of the other clamping rod 13; Attach blade 18. The bottom surface o...

Embodiment 3

[0060] On the basis of Embodiment 2, a groove 20 is provided on the inclined surface 102, and a bearing plate 21 is arranged in the groove 20. The top of the bearing plate 21 is rotationally connected with the side wall of the groove 20 through a rotating shaft 22, and is also included for driving the rotating shaft 22 to rotate. The third driving member 23; the mouse body fixing assembly and the mouse tail positioning device 3 are all located on the bearing plate 21. The carrying plate 21 is a magnetic metal plate. Rat tail positioning device 3 such as Figure 5 As shown, several magnets 24 are embedded in the bottom; the channel 4 is open from the bottom surface of the mouse tail positioning device 3 , and the inner wall of the channel 4 is covered with a layer of elastic material 25 .

[0061] Preferably, the magnetic metal plate is an iron plate, and the elastic material is a rubber pad.

[0062] In the blood taking process of the present embodiment:

[0063] Step S2 is...

Abstract

The invention discloses a mouse tail vein blood collection system, which comprises a table body, the table body includes a horizontal plane and an inclined plane, centrifugal equipment is arranged on the horizontal plane, and rat body fixing components, The mouse tail positioning device and the mouse tail clamping assembly, the mouse tail positioning device includes a channel for the mouse tail to pass through; it also includes a platform on an inclined surface, the upper surface of the platform is parallel to the horizontal plane, and the bearing There is a socket for placing the EP tube on the surface of the platform. The invention provides a mouse tail vein blood collection system to solve the problems in the prior art that it is difficult to ensure the stability of the tail of the blood to be taken during the mouse tail vein blood collection process, and it is easy to mix air bubbles in the blood sample to interfere with the follow-up experiment. Rat tail vein blood sampling for the purpose of stability and continuity.

Description

technical field [0001] The invention relates to the field of medical experiments, in particular to a mouse tail vein blood collection system. Background technique [0002] In the course of experiments in the field of medical biology, it is often necessary to take blood from mice. The traditional methods of blood collection include beheading, heart, eyeball, etc. These traditional blood collection methods will cause the death of mice, which is not conducive to repeated experiments and continuous observation. For this reason, in the prior art, mice Mice were venously bled from the tail. In the prior art, there are mainly two methods for taking blood from the rat tail vein: 1) Manually lift the tail of the mouse to hang the mouse upside down, cut the tail of the mouse to create a wound, and then take blood through the capillary. This method is safe. Low and inconvenient to operate; 2) Put the mouse into a nearly cylindrical structure, let the mouse tail pass through the throu...
