Abstract

The invention relates to a fixing device. The fixing device is used for well fixing a rat, is suitable for gavage, injection and other operations, and is also used for preventing the biting injury by the rat. The fixing device consists of a clip and a spring, wherein the clip can rotate around a center shaft, the clip is naturally expanded by the spring, teeth are arranged at the two sides of the lower part of the clip and are used for fixing the rat, the front part of each tooth is shorter, the back part of each tooth is longer, each tooth is in an arc shape, and the upper part of the clip is provided with an arm for holding by hands. The fixing device has the characteristics that the structure is simple, the operation is convenient, the safety and reliability are realized, the practicality is high, and the fixing device is suitable for animal experiment processes.

Description

A kind of hand-held fixer for rattus norvegicus

Technical field

The present invention be more particularly directed to a kind of hand-held fixer for rattus norvegicus.

Background technology

At present in experimentation, capture and fixing rat with hands, the thing by rat is bitten usually is had to occur, or there is a kind of feared state of mind, be unfavorable for zooperally normally carrying out, in addition in three grades of animals, level Four animal (germfree animal) feeding and management process, require that staff directly can not contact animal with hands.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides one and can solve and bitten and better can fix animal, being convenient to zooperal hand-held fixer for rattus norvegicus.

The technical scheme realizing above-mentioned purpose is: a kind of hand-held fixer for rattus norvegicus, by and the spring that clip can make clip naturally open can be arranged on form around the clip of central axis, it is characterized in that, below clip, both sides are the tooth of fixing rat, have certain interval between tooth and tooth, and the tooth on both sides can intersect when fixing animal, the front flank on both sides is shorter, longer below, each tooth, all in camber, is the arm of handgrip part above clip.

Further, by the position of nut regulating tooth on clip.

Further, on tooth, cover has and has elastic rubber or plastic sheath.

Further, by flute profile button fixing arm.

The invention has the advantages that, structure is simple, easy to operate, safe and reliable, practical.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Detailed description of the invention

In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:

As shown in Figure 1, the present invention is by the clip that can rotate around central shaft 1 and be arranged on the spring 2 that clip can make clip naturally open and form, below clip, both sides are the tooth 4 of fixing rat, every toothrow can arrange 8-9 tooth, certain interval is had between tooth and tooth, and the tooth on both sides can intersect when fixing animal, consider that the thin rear body of rat predecessor is thick, the tooth on both sides is shorter before being also, longer below, each tooth 4 is all in camber, by the position of nut 6 regulating tooth 4 on clip, for preventing damaging animal, on the tooth 4 of contact animal, cover has and has elastic rubber or plastic sheath 5.Be the arm of handgrip part above clip, by flute profile button 3 fixing arm.

During use, experimenter pinches rat tail tractive backward gently with a hands thumb and forefinger, the hand-held holder of another, clip is opened by central shaft and spring by holder naturally, be placed on rat back and firmly grasp animal, rat forelimb is in the first neutral gear, even if rat forelimb is stuck in above between the first tooth and the second tooth, hands tightens up holder, fixed by flute profile button, appropriateness is noted and by the position of nut regulating tooth on clip time fixing, can not to move forward and backward with animal or left-right rotation is as the criterion, finally adjust the extremity of animal, it is made to be more suitable for and experimental implementation, as anesthesia, gavage, injection, blood sampling etc.

The present invention can adopt stainless steel tube material or other light-duty hard material, can carry out high temperature, high pressure, medicine sterilization.

Claims
