Abstract

The utility model relates to a fixing device which can fix white rats, is suitable for operation of intragastric administrations, injection, etc. and can also prevent people from being bitten by the white rats. The utility model is composed of a clamp and a spring, wherein the clamp rotates around a central shaft, and the spring makes the clamp naturally unfolded; both sides of the lower part of the clamp are provided with teeth for fixing white rats, the front parts of the teeth are short, the back parts are long, and the teeth form an arc shape; an arm which is a hand holding part is arranged on the clamp. The utility model has the advantages of simple structure, convenient operation and high safety, and is suitable for being used in the process of animal experiments.

Description

Rat is handed holder

This utility model relate to a kind of can be fixing preferably in the zoopery process rat, be fit to do and irritate operations such as stomach, injection, can prevent the fixture of being bitten again by rat.

At present in experimentation, grasp and fixing rat with hands, usually there is the thing of being bitten to take place by rat, a kind of feared state of mind is perhaps arranged, be unfavorable for zooperally normally carrying out.In three grades of animals, level Four animal (germfree animal) feeding and management process, require the staff directly not contact animal in addition with hands.

The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of fearness that can solve by the fear of biting and causing, it is fixing preferably that animal is obtained, and is convenient to the hand-held holder of rat of zooperal operations.

The purpose of this utility model is achieved in that by can with being arranged on the open naturally spring of clip being formed around the clip that central shaft rotates, both sides are the fixing tooth of rat below the clip, between tooth and the tooth certain interval is arranged, and the tooth on both sides can intersect when fixing animal, the front flank on both sides is shorter, and the back is longer, and each tooth all is camber, the top of clip is the arm of handgrip part, by sawtooth pattern button fixing arm.

The utlity model has characteristics simple in structure, easy to operate, safe and reliable, practical.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is a structural representation of the present utility model.

As shown in Figure 1, this utility model is by can with being arranged on the open naturally spring 2 of clip being formed around the clip that central shaft 1 rotates, both sides are the fixing tooth 4 of rat below the clip, respectively there is 7-8 tooth on both sides, between tooth and the tooth certain interval is arranged, and the tooth on both sides can intersect when fixing animal, promptly not on a plane, consider that rat predecessor thin back body is thick, the tooth on both sides also is that the front is shorter, the back is longer, and each tooth all is camber, and the top of clip is the arm of handgrip part, by sawtooth pattern button (3) fixing arm, by central shaft 1 and spring 2 clip is opened naturally, promptly can reach the fixedly purpose of animal by sawtooth pattern button fixing arm behind the animal.Can pass through nut 6 positions of regulating tooth 4 on clip.For preventing that animal is damaged, be with rubber-like rubber or plastic sheath 5 on the tooth 4 of contact animal.This product can adopt rustless steel (pipe) material or other light-duty hard material, can carry out high temperature, high pressure, medicine sterilization.

Use: hands thumb and forefinger pinch rat tail tractive backward gently, the another hands is taken holder, after holder is opened naturally, be placed on the rat back, the rat forelimb is in first neutral gear, even the rat forelimb is stuck between 1,2 teeth of front, hands tightens up holder, and utilize the sawtooth pattern button to be fixed, note appropriateness in the time of fixedly, and can regulate by nut, can not move forward and backward or left-right rotation is as the criterion with animal, adjust the extremity of animal at last, it is more suitable for and experimental implementation, as anesthesia, filling stomach, injection, blood sampling etc.For preventing that animal is damaged, be with rubber-like rubber or plastic sheath 5 on the tooth 4 of contact animal.This product can adopt rustless steel (pipe) material or other light-duty hard material, can carry out high temperature, high pressure, medicine sterilization.
