[0002] The catheterization device for animal experiments is a convenient urine quantitative and auxiliary physical and chemical property determination in the process of animal urinary tract system experiments. The existing animal urine production experimental instrument ureter cannula is inserted in the middle of the lower abdominal wall after the animal is anesthetized. The longitudinal surgical incision exposes the bilateral ureters, and the two tips of the upper ureteral cannula are inserted into the bilateral catheters for urinary catheterization. However, the current urinary catheterization device for animal urine production experiments has some defects, such as the bracket cannot be adjusted. , it is inconvenient to conduct catheterization in animal experiments, and in the process of catheterization, the amount of catheterization cannot be controlled

The invention relates to a catheterization device for animal experiment, comprising a base, lifting mechanisms, a workbench, a collecting bottle, a drainage tube, a plug and a flow limiting mechanism;the lifting mechanism and the collecting bottle are arranged on the base; each lifting mechanism comprises a threaded sleeve, a lead screw and a disc, wherein the threaded sleeve is vertically fixedonto the base, the lead screw penetrates the disc, one end of the lead screw is movably connected with the workbench through a bearing and the other end thereof extends into the threaded sleeve and isin threaded connection with the inner wall of the threaded sleeve; the drainage tube penetrates the workbench, with one end connected with the plug and the other end connected to the collecting bottle; the flow limiting mechanism sleeves the drainage tube. The height of the workbench can be regulated by screwing to allow the lead screw to lift or fall inside the threaded sleeve; the flow limitingmechanism presses and limits the drainage tube to limit flow rate of urine. The catheterization device is simple in structure, easy to operate, high in practicability, and easy to promote and apply.
