Abstract

The invention provides a fixing device used for rat thoracico-abdominal puncturing. The fixing device includes a fixing cover on the upper portion and a base on the lower portion; the upper portion of the base is provided with a rat placement bottom groove in the length direction, and a rat placement top groove is formed in the position, corresponding to the rat placement bottom groove, on the fixing cover; the bottom of the rat placement bottom groove is open, the lower surface of the base is covered with a puncturing net, the base and the fixing cover are fixed through a fixing device body on the base, and the puncturing net is formed by standard meshes with the standard scale. According to the fixing device, based on the size of a rat, the size of rat placement space can be adjusted, and the fixing device is thus suitable for rats different in size; the puncturing net with the standard scale is used for fixing, the thorax and the abdomen can be exposed fully, and according to the standard mesh scale, positioning puncturing is conducted; the fixing device is suitable for rat tail vein blood sampling and other experiments and has multiple functions. The problem that an existing rat abdominal drug delivery fixing device can not prevent rats from turning freely in a fixer and thus drug delivery is affected can be well solved.

Description

technical field

[0001] The invention relates to the technical field of experimental equipment, in particular to a fixing device for rat thoracoabdominal puncture. Background technique

[0002] In the fields of medicine, biology and other sciences, rats are often used as research objects for animal research. At present, the intraperitoneal administration and anesthesia methods of laboratory rats mainly stay at the stage of manual operation. Rats have poor obedience and strong aggressiveness. Personnel are easily scratched and bitten during operation; in addition, grasping and pinching rats with bare hands will cause discomfort to rats, thereby increasing the stress response of rats and affecting the credibility of experimental results to a certain extent.

[0003] Currently commercially available rat fixators have unsatisfactory fixation effects, and the chest and abdomen cannot be exposed after fixing rats in a non-anesthetized state. I have proposed a patent named "Adjusta...

Examples

Embodiment Construction

[0025] The present invention will be further described below in conjunction with examples, but the present invention is not limited to these examples.

[0026] The rat thoracoabdominal puncture fixation device described in this embodiment, as attached figure 1 As shown, it includes a lower base 20 and an upper fixed cover 10 , and the fixing of the base 20 and the fixed cover 10 is realized by a fixing device 23 . A pair of height adjustment grooves 13 with top openings are respectively arranged on both sides of the fixed cover 10, and the position of the notch is corresponding to the fixing device 23 that is threaded on the base 20 in the vertical direction. The adjustment slot 13 slides up and down, and the fixing of the fixing cover 10 and the base 20 is realized by tightening the fixing device 23 , which is easy to operate.

[0027] as attached figure 2 As shown, the base 20 includes a front baffle 24 arranged at the front end, two parallel beading bars 30 vertically co...
