Mouse tail vein blood sampling and injection clamp

Abstract

The invention discloses a mouse tail vein blood sampling and injection clamp. The mouse tail vein blood sampling and injection clamp comprises a fixing device and a handle device; the fixing device comprises magnetic fixing plates, a fixing opening and a bolster sheet, the magnetic fixing plates can fix the mouse tail to a magnetic panel or a metal plate, the fixing opening is located between a connecting shaft and the front-end magnetic fixing plates, and the rubber bolster sheet is placed in an inner groove of the fixing opening, and is thin at front and thick at back in the horizontal direction of the inner groove; the handle device comprises a spring sheet, handles and the connecting shaft, and the spring sheet is fixed to the inner sides of the handles and used for pressurizing the handles. The mouse tail vein blood sampling and injection clamp has the advantages that that the mouse tail vein blood sampling and injection clamp is simple in structure, small in size and convenient to carry; the rubber bolster sheet is arranged in the clamp and is thin at front and thick at back in the horizontal direction of the inner groove, which conforms to the physiological curvature of themouse tail; the clamp is convenient to operate, and capable of fixing the mouse tail from multiple angles and quickly filling the vein of the mouse tail, tail vein puncturing is facilitated, the timeis saved, the labor can also be saved, and the mouse tail vein blood sampling and injection success rate is increased.

Description

technical field [0001] The invention relates to the technical field of animal experiment equipment, in particular to a mouse tail vein blood collection and injection clip. Background technique [0002] Mouse animal experiments play an extremely important role in medical research, and mouse tail vein puncture is the most commonly used experimental method for modeling, drug delivery, and blood collection. However, due to the different depths and uneven thicknesses of the tail veins of mice, the existing mouse tail fixers do not have a good fixer when injecting mice. The fixation effect of the existing mouse tail fixers is not ideal, and it cannot be fixed for all mice , has certain limitations, the safety performance is not high, and the fixation is not firm, which makes the experiment very difficult and the failure rate remains high, especially the tail vein of the small black mouse is more difficult to operate. Failure to puncture the tail vein means an increase in the cost...
