Embodiment 1

[0042]Such asfigure 1 versusfigure 2 A mouse tail vein tension system, including a small body 1, a table body 1 including a horizontal plane 101, an inclined surface 102, a horizontal plane 101, a casing, and a slope 102, and then set a mouse fixing assembly in turn. Mouse tail positioning device 3, sage clamping assembly, the mouse tail positioning device 3 includes a passage 4 for a murray; further comprising a bearing 5 located on the bevel 102, the upper surface of the upper surface 5 is parallel to the horizontal plane 101, and A jack 6 for placing an EP tube is opened on the upper surface of the jack 5.

[0043]Among them, the mouse fixing assembly includes a plurality of curved limit members 7, and the height and width of the internal passage of the half tapeed tube 8 are located between the arc limit member 7 and the mouse tail positioning device 3. The inclined direction is gradually reduced from the top and bottom, and the bottom end of the heating cylinder 8 is in communicat...

Embodiment 2

[0046]Such asFigure 1 to 4A mouse adjuverelet blood system, on the basis of Example 1, the mouse tail clamp assembly includes a first sliding rail 12 disposed on the inclined surface 102, sliding two in the first sliding rail 12. The root clamping rod 13, the axis of the first slide rail 12 is parallel to the horizontal plane 101; any one of the clamping rods 13 connects the first driving member 14, the first driving member 14, the first drive The member 14 is used to drive the connected clamping rod 13 to perform a linear movement along the first sliding rail 12. Any side surface of any one of the clamping rods 13 is in the direction of the direction in which the clamping rod 13 is in a concave curved surface. One of the tops of one of the clamping rods 13 is connected to the mounting member 15, and the mounting member 15 extends toward the other holding rod 13; the mouse tail sensing device 16, the telescopic device 17, and the telescopic device 17 are fixed at the bottom of the m...

Embodiment 3

[0060]On the basis of the second embodiment, the groove 20 is opened on the sliding surface 102, and the carrier plate 21 is provided in the groove 20, and the top of the carrier plate 21 is rotatable with the groove 20 side wall, and further includes driving the shaft 22 rotation. The third drive 23; the mouse fixing assembly is located on the carrier plate 21. The carrier plate 21 is a magnetic metal plate. Mouse tail positioning device 3Figure 5 As shown, a number of magnets 24 are embedded at the bottom; the passage 4 is open from the bottom surface of the mouse tail positioning device 3, and the inner wall of the passage 4 coated a layer of elastic material 25.

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

[0062]The blood circulation of this embodiment is:

[0063]Step S2 is specifically: first remove the mouse tail positioning device, and then fix the mice after the mouse fixing assembly, then the noise positioning device is buckl...

Abstract

The invention discloses a mouse caudal vein blood sampling system which comprises a table body, wherein the table body comprises a horizontal plane and an inclined plane, centrifugal equipment is arranged on the horizontal plane, a mouse body fixing assembly, a mouse tail positioning device and a mouse tail clamping assembly are sequentially arranged on the inclined plane from top to bottom, and the mouse tail positioning device comprises a channel allowing a mouse tail to penetrate through; and the mouse caudal vein blood sampling system also comprises a bearing table, the upper surface of the bearing table is parallel to the horizontal plane, and an inserting hole used for containing an EP pipe is formed in the upper surface of the bearing table. The invention provides the mouse caudal vein blood sampling system to solve the problems that in the prior art, in the mouse caudal vein blood sampling process, it is difficult to guarantee the stability of the tails subjected to blood sampling, and bubbles are likely to be mixed into blood samples to interfere with subsequent experiments, and the purpose of improving the stability and continuity of mouse caudal vein blood sampling is achieved.

Description

Technical field[0001]The present invention relates to the field of medical experiment, and more particularly to a mouse tail vein tension system.Background technique[0002]During the experiment in the field of medical bounter, mice often need to be intravenous. Traditional tensioned methods have broken heads, cardiac blood, eye-catching blood, etc. This kind of traditional bleeding method can cause mice to die, not conducive to repetitive experiments and continuous observation, and start from the prior art Mice were intravenous for intravenous blood. The prior art is mainly divided into the following two types: 1) Artificial mouse tail to make mice floating, cutting away the tail, creating a cumulope, and taking the capillary, this way safety Low and operating inconvenience; 2) Put the mice into the hierarchical structure so that the murine is tail in the through hole of the bottom of the cylinder, and then manually cut the tail of the hook, which is higher in this manner. However, t...
