Embodiment 1

[0038] Embodiment 1, the simple catch and fixation device that is used for rabbit experimental animal

[0039] The device includes an introducer and a fixed net ( figure 1 ), the inlet 3 of the fixed net is directly overcoated and connected to the outlet 2 of the introducer. The introducer is a white hollow plastic cone with diameters of 40cm and 30cm at the upper and lower ends, respectively. The fixed net is a cotton net with an entrance diameter of 45cm and square holes, and each mesh has 4 areas of 2.5cm 2 , the diameter of the cotton weaving mesh line is 0.2cm, and a cotton weaving ring closing line 5 with a length of 100cm and a diameter of 0.3cm is provided at the entrance.

[0040] The method of using this device is: put the introducer directly into the fixed net, hold both ears of the experimental rabbit, and put it into the introducer from the front of the tail to the rear; after the experimental rabbit slides into the fixed net, remove the introducer and tighten i...

Embodiment 2

[0042] Embodiment 2, professional catch and fixation device for rodent experimental animals

[0043] This device includes an introducer, a fixed net and a sleeve ( figure 1 , figure 2 ), the entrance 3 of the fixed net is hooked on the outlet 2 of the importer. Both introducers are hollow plastic conical frustums. The diameters of the upper and lower ends of one introducer are 20cm and 8cm respectively, and the diameters of the upper and lower ends of the other introducer are 10cm and 5cm respectively. The two introducers are used separately and are suitable for For the capture of rats and mice, the two introducers can also be used directly on the hub, which is suitable for the capture of mice. The fixed net is a cotton net with a diamond-shaped hole in the entrance diameter of 22cm, and each mesh has 4 areas of 2cm 2 , the diameter of the cotton weaving mesh wire is 0.2cm, and a cotton weaving closing line 5 with a length of 100cm and a diameter of 0.3cm is provided at th...

Embodiment 3

[0045] The device is simple and easy to operate. The purpose of increasing the sleeve is to make the inside of the whole device dark and easy to lure mice into the net. Embodiment 3, be used for the capture fixation device that needs to fix experimental animal for a long time

[0046] The device includes an introducer, a fixed net and a fixed plate ( figure 1 , image 3 , Figure 4 , Figure 6 ), the inlet 3 of the fixed net is directly socketed on the outlet 2 of the importer. The introducer is a hollow white plastic cone with diameters of 40cm and 30cm at the upper and lower ends, respectively. The fixed net is a nylon mesh with a diamond-shaped hole in the entrance diameter of 42cm, and each mesh has 4 areas of 9cm 2 , the diameter of the nylon mesh cable is 0.2cm, and the entrance is provided with a nylon closing line 5 with a length of 100cm and a diameter of 0.3cm.

[0047] Fixing plate is long 60cm, wide 50cm, the wooden plank 6 of thick 2.0cm, there is rectangula...

Abstract

A tool for capturing and fixing the experimental animal is composed of a hollow cylindrical gatherere, a conical or cylindrical fixing net whose entrance is connected to the exit of said gatherer, and the optional barrel fixed to the lower end of fixing net, and / or fixing plate for the experimented animal and / or fixer with operating unit. Its advantages are no damage of animal to human head, high efficiency and low cost.

Description

technical field [0001] The invention relates to the field of experimental zoology, in particular to a device for experimental animals, more specifically to a catch and fixation device for experimental animals. Background technique [0002] When conducting animal experiments in the laboratory, it is often necessary to inject drugs (such as intraperitoneal injection, intramuscular injection or subcutaneous injection) or gavage, oral drug feeding and blood collection to animals such as mice, rats, guinea pigs or rabbits. One of the biggest problems is how to safely and effectively capture and fix experimental animals, and then perform various operations on the animals. Because animals are generally afraid of strangers touching their bodies, and even more defensively resist various unconditional stimuli, it is very difficult to capture and fix experimental animals, and work experience has further confirmed this point. [0003] For example, the usual way to capture and fix Sprag...
