Problems solved by technology

The main reason for the difficulty of endnote work is the lack of dedicated fixtures
Because the veins of the tail of the rat are very small, it is difficult to locate them accurately, and the tail of the rat is not easy to fix. Therefore, in the absence of a special fixing device, the staff cannot ensure the success rate of the endnote

Embodiment Construction

[0009] Such as figure 1 As shown in the present invention, the experimental mouse tail vein visual fixer includes a base 1 . A fixed block 2 and an adjusting rod 5 are installed on the base 1 . Such as figure 2 As shown, one end of the adjusting rod 5 is movably connected with the fixed block 2 or the base 1, and the other end of the adjusting rod 5 is provided with a tailstock 6. The distance between the tailstock 6 and the fixed block 2 can be adjusted by adjusting the adjusting rod 5, so that the injection part is all located on the tailstock 6 no matter when injecting at any part of the mouse tail. Such as Figure 7 Shown, tailstock 6 tops offer chute 11, and on the sidewall of chute 11, yellow light 12 is embedded, and yellow light 12 is irradiated horizontally. The yellow light 12 was discovered by accident in the experiment. The spectral range it emits is: 620nm----570nm, that is, the light in the range of orange-yellow to yellow-green. It can not only clearly show...

Abstract

The invention discloses an experimental visual rat tail vein fixator comprising a base, wherein the base is provided with a fixed block and a regulating rod; one end of the regulating rod is movably connected with the fixed block or base, and the other end of the regulating rod is provided with a tail supporting frame; the distance between the tail supporting frame and the fixed block can be regulated through regulating the regulating rod; the top of the tail supporting frame is provided with a chute; a horizontally-irradiating yellow fluorescent lamp is embedded in the side wall of the chute; the fixed block is provided with a first fixed groove; the fixed block is provided with a pressing block which can be opened or closed relative to the fixed block so as to press or release a rat tail. The experimental visual rat tail vein fixator also has the advantages of simple and compact structure, low manufacturing cost as well as simplicity and convenience in use.

Description

technical field [0001] The invention relates to an animal experiment equipment, in particular to a visual fixer for rat tail veins used in experiments. Background technique [0002] The tail vein administration of rats and rats used in the experiment is called endnote. Endnote is the most common daily work in physiological, pharmacological, and toxicological experiments. At present, the work of endnotes is a difficult task with extremely high skill and precision. Even for experienced staff, it is not an easy and easy task. In experiments, due to improper operation, the drug is often not injected. Into the tail blood vessel of the animal, the animal is discarded, thus, the situation that the whole experiment is in vain. The main reason why endnotes work is so difficult is the lack of dedicated fixtures. Because the veins of the tail of the rat are very small, it is difficult to locate them accurately, and the tail of the rat is not easy to fix. Therefore, in the absence of...
