Tail intravenous injection fixator for mice

Abstract

The invention relates to a tail intravenous injection fixator for mice, and belongs to experiment auxiliary tools for mice. The fixator comprises a base; a fixing box fixedly connected at the top of the base, wherein one end of the fixing box is provided with an adjustment opening, the top of the fixing box is provided with a top opening, and one side of the fixing box is provided with a clampingopening; a push plate that is arranged at a clamping opening; a driving device of which the output end is fixedly connected to one side of the push plate; a cover plate that covers the top opening; anadjustment door plate for sealing the adjustment opening, wherein the adjustment door plate is provided with a tail exposing hole; a tail support table of which one end is fixedly connected to one side face of the adjustment door plate away from the fixing box; and a water bath that is arranged on the fixing box and located vertically below the tail support table. The fixator of the present invention can be used to fix mice with different body types, and has a good fixation effect on mice. Meanwhile, the fixator can heat tails of the mice, thereby facilitating the observation of veins.

Description

technical field [0001] The invention belongs to a mouse test auxiliary tool, in particular to a mouse tail vein injection fixer. Background technique [0002] Tail vein injection of mice is often used for pharmacology, efficacy and toxicity test evaluation. When injecting mice into the tail vein, because the tail vein of the mouse is small, it is extremely difficult to insert the needle, and it is also difficult to distinguish with the naked eye. At the same time, mice are prone to resisting activities, which makes it difficult to inject into the tail vein of mice. At present, the mouse is generally fixed by a fixation device, and then injected into the tail vein of the mouse. [0003] However, the current fixation device cannot be adjusted due to the difference in the size of the mice, resulting in a poor fixation effect on the mice, which is still unfavorable for researchers to operate. [0004] In addition, traditional syringes are mainly used for tail vein injection o...

[0003] However, the current fixation device cannot be adjusted due to the difference in the size of the mice, resulting in a poor fixation effect on the mice, which is still unfavorable for researchers to operate

[0004] In addition, traditional syringes are mainly used for tail vein injection of mice at present, and because the tail veins of mice are small, it is extremely difficult to insert the needle. When the size of the traditional syringe is too large, the needle cannot enter the blood, and the size of the traditional syringe is too small, so it is easy to puncture the vein. Even the tail is pierced, thus very unfavorable for mouse tail vein injection
