A mouse tail vein injection device

Abstract

A tail vein injection method for mice, involving an injection method, the tightening bolt (24) is screwed counterclockwise, the clamping of the U-shaped splint (12) is loosened, and the device (1) is rotated clockwise by hand to make the device ( 1) In a vertically placed state, turn the tightening bolt (24) clockwise to clamp and fasten the U-shaped splint (12) and the vertical plate (23), and fix the position of the device (1); the invention discloses A mouse tail vein injection method was developed. During the pharmacological experiment, it can realize the immobilization of mice that meet different specifications and body weights, and the integration of mouse placement and injection process. The body weight is limited and the mouse needs to be "stuck" for the inconvenience of filling. The invention is convenient to operate and optimizes the mouse filling method and the tail vein injection operation of the mouse.

Description

technical field [0001] The invention relates to an injection device, in particular to a mouse tail vein injection device. Background technique [0002] The pharmacological experiment stage is divided into in vitro experiment, animal experiment and clinical experiment (human body). In animal experiment, drug development is a necessary stage before it is applied to human body. The impact of drug entering human body is irreversible, and the effect of depletion often brings The human body is painful and even endangers life, so it must be observed through a large number of animal experiments for a long time. Animal pharmacological experiments can effectively evaluate the efficacy, safety and other indicators of drugs. It can help to determine the safe dose range of drug application, avoid damage caused by excessive dose, and help to avoid or reduce the incidence of adverse drug reactions in the human body. Animal experiments have become an indispensable and important experiment...

Problems solved by technology

[0013] In order to overcome the deficiencies in the background technology, the present invention discloses a mouse tail vein injection device, which can realize the immobilization of mice satisfying different specifications and body weights and the integration of the mouse placement and injection process during the pharmacological experiment, and solve the problem of In the traditional pharmacological experiment, the weight of the mouse is limited by the fixing device and the inconvenience of "hard plugging" is required when filling the mouse. The invention is convenient to operate and optimizes the filling method of the mouse and the tail vein injection operation of the mouse.
