Problems solved by technology

At present, the commonly used immobilizers for rats and mice mainly fix the front and rear limbs. When the rats and mice are struggling, the front and rear limbs still have a certain degree of mobility, and there is still the possibility of scratching the experimenter. More importantly, it is not convenient for fine manipulation of the front and rear paws.

Embodiment 1

[0017] refer to Figure 1-3 , a kind of fixer for rats and mice, comprising a transparent cuboid box 1, the top of the transparent cuboid box 1 includes a top plate 3, a fixed splint 4 fixed at the end of the top plate 3, and a sliding splint 5 sliding on the top plate 3; the top The opening semicircle holes on the sliding splint 5 on both sides and the opening semicircle holes on the fixing splint 3 form claw fixing holes 8, and the right side plate of the transparent cuboid box 1 is a detachable tail plate 6, The bottom of the tail gusset 6 is provided with an open tail fixing hole 7 .

[0018] When using this technical solution, open the tail plate 6, open the sliding splint 5 to form a chute and an open claw fixing hole 8. Put the paws of the rat and the mouse upwards and put the head side first into the holder, that is, the inside of the transparent cuboid box 1, move the front and rear paws in the chute and close the sliding splint 5 at the paw fixing hole 8 suitable fo...

Embodiment 2

[0022] Based on the first embodiment, the right side of the top plate 3 is provided with a chute 10 to facilitate the sliding of the sliding splint 5 , and one end of the sliding splint 5 is provided with a sliding handle 9 inserted into the chute 10 . Slide connection for easy handling.

Embodiment 3

[0024] Based on the first embodiment, a slot for fixing the fixed splint 4 and the sliding splint 5 is provided at the upper inner part of the tail gusset 6 corresponding to the fixed splint 4 and the sliding splint 5 . The tail gusset 6 plays a fixing role to the fixed splint 4 and the sliding splint 5 .

Abstract

The invention discloses a rat and mouse fixator. The rat and mouse fixator comprises a transparent cuboid box, wherein the top of the transparent cuboid box comprises a top plate, a fixed clamping plate fixed at the end part of the top plate, and a sliding clamping plate sliding on the top plate; opening semicircular holes in the sliding clamping plate on two sides of the top and opening semicircular holes in the fixed clamping plate form claw part fixing holes; a right side plate of the transparent cuboid box is a tail buckle plate which is detachably arranged; and an opening type tail fixing hole is formed in the bottom of the tail buckle plate. Compared with the prior art, the rat and mouse fixator is simple in structure, low in production cost and convenient to carry and use, facilitates fine operation of front and rear claws and tails of rats and mice, and prevents biting and scratching.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fixer for fixing front and rear paws and tails of rats and mice. Background technique [0002] Rats and mice are commonly used experimental animals in medical research. They are widely used as experimental animals in experiments in pharmacology, oncology, physiology, pathology and other disciplines. Rats and mice should be prevented from biting and scratching during experimental operations. Tail refinement, such as tumor cell planting, microinjection of lymphatic dye, and tail vein blood collection, requires good fixation of the front and rear paws and tail of rats and mice. At present, the commonly used immobilizers for rats and mice mainly fix the front and rear limbs. When the rats and mice are struggling, the front and rear limbs still have a certain degree of mobility, and there is still the possibility of scratching the experimenter. More importantly, it is not co...
