Abstract

The utility model discloses a compensate prior art's defect, provide a mouse fixer for experiments. The characterized by ware body is by the triplex: fixation clamp, funnel, spring. The fixation clamp is stretched into inside the funnel by the funnel exit. On placing the laboratory bench with the mouse, being the funnel and invering the form and detain in the mouse top, restrict its activity, the spring lower extreme has the spring stop integrative with the handle, lifts the handle and makes spring compression, pushes down the direction according to mouse position adjustment, makes the mousetail stretched out by the semi -circular hole crack at funnel wall edge to tail intravenous route carries out. There are two circular bleeder vents on the funnel wall to the space lead to the mouse to be choked to death because of being narrow and small. Utilize this fixer fixed mouse fast, expose and to carry out the afterbody injected to carry out the accuracy injection. This fixer can reduce mouse struggle space, improves experimental efficiency, avoids the experimenter be injured.

Description

A kind of laboratory mice holder

Technical field

This utility model relates to Medical fundamentals and drug inspection field, particularly to a kind of laboratory mice holder.

Background technology

Mice is as a kind of laboratory animal, because it is small, docile, quantity is many, be prone to breeding, the first-selected experimental subject often tested as medicinal pharmacology.It is arrested, fixes by experiment often, then carries out tail vein injection.Mice is the most active, and it is arrested and is often difficult to fixing means be grasped by abecedarian, causes injection can not accurately inject desired location, causes the failure of an experiment.Meanwhile, the phenomenon that experimenter is scratched by mice or bites happens occasionally, and once this thing happens, often delays experiment process, and experimenter causes unnecessary injury.

Summary of the invention

This utility model is in order to make up the defect of prior art, it is provided that a kind of laboratory mice holder.

This utility model is achieved through the following technical solutions:

It is characterized in that body is made up of three parts: fixation clamp, funnel, spring.Fixation clamp is stretched into inside funnel by funnel exit.When arresting mice, funnel is buckled in above mice in being inverted shape, limits its activity, and lower spring end has and the spring stop of handle one, upper handle makes spring-compressed, press direction according under mice position adjustment, make mousetail be stretched out by the semicircle hole of hopper walls lower edge, in order to carry out tail vein injection.Two circular air-vents are had on hopper walls, in order to avoid because narrow space causes mice to be choked to death.There is metal weights on handle, prevent mice from struggling and holder is thrown.

The beneficial effects of the utility model are: this holder can be utilized quickly to fix mice, expose the afterbody needing to carry out injecting, in order to carry out accurate injection.Reduce mice struggle space, improve conventional efficient, it is to avoid experimenter is injured.

Accompanying drawing explanation

Below in conjunction with the accompanying drawings this utility model is further described:

Accompanying drawing 1 is the structural representation of this utility model laboratory mice holder.

In figure, 1 handle, 2 springs, 3 fixation clamps, 4 air-vents, 5 semicircle holes, 6 funnels, 7 counterweights, spring stop 8.

Detailed description of the invention

Accompanying drawing is a kind of specific embodiment of the present utility model.

It is characterized in that body is made up of three parts: fixation clamp 3, funnel 6, spring 2.It is internal that fixation clamp 3 is stretched into funnel 6 by funnel 6 exit, there is handle 1 upper end, hold handle 1 and funnel 6 is buckled in above mice, limit it movable, spring 2 lower end has and the spring stop 8 of handle 1 one, and upper handle 1 makes spring 2 compress, presses direction according under mice position adjustment, mousetail is made to be stretched out by the semicircle hole 5 of funnel 6 mural margin, in order to carry out tail vein injection.Two circular air-vents 4 are had, in order to avoid narrow space causes mice to be choked to death on funnel 6 wall.There is metal weights 7 on handle 1, prevent mice from struggling and holder is thrown.

Claims

1. a laboratory mice holder, it is characterized in that: it is internal that fixation clamp (3) is stretched into funnel (6) by funnel (6) exit, spring (2) lower end has and the spring stop (8) of handle (1) one, utilize and press direction under spring (2) regulation, counterweight (7) is had on handle (1), air-vent (4), funnel (6) edge is had to have semicircle hole (5) on funnel (6).
