A device for tail vein and other superficial vein injection in mice

Abstract

The invention relates to a device for intravenous injection of a mouse tail and superficial intravenous injection of other parts. The device comprises a base, a transparent tube, a front fixing part and a rear fixing part, wherein a notch is formed in the rear fixing part, and ventilation holes are formed in two side edges of the transparent tube; the base is a closed cavity with a light source inside, the base comprises a top plate, a soleplate and four side plates, an adjustable light-transmitting operation panel which is hinged to the top plate is arranged between the side plate facing one end of the tail part of a mouse and the top plate, the side edge of the top plate is provided with a fixing plate facing the interior of the base, the adjustable light-transmitting operation panel is provided with an angle adjusting screw for adjusting an angle between the adjustable light-transmitting operation panel and the fixing plate, and other three side edges of the adjustable light-transmitting operation panel are respectively provided with an elastic light screening plate which is connected to the side edge of the adjacent base. By adopting the device, the safety of the operator is adequately guaranteed, and the operator can be prevented from being bitten by the mouse when in injection; moreover, the mouse is firmly fixed, the stress response of the mouse can be prevented from affecting the experiment result, and the experiment result is more reliable.

Description

technical field [0001] The invention relates to the field of medical auxiliary equipment, in particular to a device for injecting mice into tail veins and other superficial veins. Background technique [0002] With the slowdown of global economic growth and the high cost of scientific research, the loss of scientific research caused by cost pressure is shocking. Mice are favored by the industry because of their low cost, small size, and ease of feeding. In particular, the cost of using a single reagent is one-tenth or even less than that of medium-sized animals. However, due to the small size of mice and the extremely thin tail veins and other superficial veins, it is difficult to implement traditional intravenous drug delivery methods in mice, which has become a problem that hinders the widespread application of mice in many fields. At present, there is no device on the market that can be applied to the tail vein of mice and other superficial vein injections. The only auxi...
