Abstract

The invention relates to a mouse tail vein injection fixing device and a using method thereof. The mouse tail vein injection fixing device comprises a fixator and an object table, the fixator comprises a fixing barrel and a magnet fixing box, the fixing barrel comprises a slit, an annular piece and a barrel door, one end of the fixing barrel is perpendicularly connected with the magnet fixing box, the barrel door is arranged at the other end of the fixing barrel, a tail detecting hole is formed in the barrel door, a square magnet block is disposed in the fixing box, the slit is formed in the fixing barrel, and the annular piece is arranged in the fixing barrel, moves along the slit and is connected with the fixing barrel through a nut and a screw penetrating the slit. By the mouse tail vein injection fixing device, size of the fixing barrel can be adjusted according to body length of a mouse; the mouse tail vein injection fixing device can be adsorbed on any iron-containing plane (such as an isolating wall, a refrigerator and a mouse cage frame) for use, and height and rotating angle can be adjusted freely to find an optimal position, so that distance between the tail of the mouse and eyes of a person is shortened, and injection success rate is increased. In addition, the object table is arranged to cooperate with the fixator, so that convenience is brought to fetching and using of objects like syringes and alcohol cotton balls.

Description

Technical field [0001] The invention relates to an animal fixing device for experiment, in particular to a mouse tail vein injection fixing device and a method of use thereof. Background technique [0002] Mouse tail vein injection is often used for drug screening and acute toxicity tests. Traditional mouse tail vein injection fixtures are mostly cylindrical with an opening at one end and can be closed, and the other end can be breathable. During injection, the mouse is stuffed into a cylindrical shape, one end of the cylindrical shape is closed, and the tail of the mouse is exposed through the opening at the end for tail vein injection. There are also some modified models that can adjust the space of the fixed cylinder according to the length of the mouse. However, the current mouse tail vein injection fixator still has the following shortcomings (take the fixation device published in Chinese Patent CN102451046A as an example): [0003] a. Trouble to use. First open the engag...
