Laboratory mouse holder

Abstract

The invention discloses an experimental instrument, in particular to a laboratory mouse holder, comprising a first clamp arm, a second clamp arm, a first clamp sheet and a second clamp sheet. The first clamp arm is in crossing connection with the second clamp arm through a torsion spring. The torsion spring divides the first clamp arm into a first clamping end and a first handle. The torsion spring divides the second clamp arm into a second clamping end and a second handle. Both the first clamp sheet and the second clamp sheet are arc shaped. A first compression spring is disposed between a convex face of the first clamp sheet and the first clamping end. A second compression spring is disposed between a convex face of the second clamp sheet and the second clamping end. The first clamp sheet and the second clamp sheet are disposed between the first clamping end and the second clamping end. A concave face of the first clamp sheet faces a concave face of the second clamp sheet. The holder can replace a human hand to hold a laboratory mouse in a mouse cage, protecting a laboratory technician from being bitten. The holder is applicable to scientific research experiments, such as medical experiments, pharmaceutical experiments and biological experiments.

Description

technical field [0001] The invention relates to an experimental instrument, in particular to an experimental mouse holder. Background technique [0002] Experimental mice are the most commonly used experimental animals in scientific research, involving many scientific research fields such as medicine, pharmacology, pathology, biology, and microbiology. Experimental mice are generally kept in cages. When experimenters need to take experimental mice for experiments, they generally use the method of directly grabbing the tail of the experimental mice to bring them out. Because the experimental mice will avoid, especially when there are many mice in the cage at the same time, the experimental mice will shrink into a ball, close to each other, and the tails cannot be exposed. At this time, the traditional method is to fiddle with the experimental mice to drive them away. , when the experimental rat ran, its tail dropped violently, and the experimenter took the opportunity to gra...

Problems solved by technology

This method is easy to cause personal injury, especially the SD rats in the laboratory are more ferocious, and people are often bitten by directly fixing the head with hands, so it is very useful to invent a mechanical clamping device to assist the head fixation of experimental rats. necessary

[0003] The Chinese patent document with the publication number CN203943762U discloses a mechanical clamping device for assisting the head fixation of experimental mice, including a left head clamp and a right head clamp. The tail end of the left head clamp is connected to one end of the left pull rod through the left joint shaft to form a hinge. Structure, the tail end of the right head clip is connected to one end of the right tie rod through the right joint shaft to form a hinge structure, and the other end of the left tie rod and the other end of the right tie rod are connected to the lower end of the lifting rod through the middle joint shaft to form a compound hinge structure; The side of the clip facing the right head clip and the side of the right head clip facing the left head clip have a protruding end with a positioning hole. The positioning hole on the left head clip cooperates with the positioning shaft of the front shell to form a rotating pair. The positioning hole on the clamp cooperates with the positioning shaft of the rear shell to form a rotating pair, and the positioning shaft of the front shell and the positioning shaft of the rear shell are buckled together to form a hinge structure. Corresponding to the clamping device, it is easy to cause personal injury
