Description

Technical Field

[0001] The present invention relates to the technical field of medical tools, and particularly relates to a non-invasive modeling device for a rat model of chronic non-bacterial prostatitis. Background Art

[0002] Chronic non-bacterial prostatitis accounts for about 90% of prostatitis, which refers to the chronic inflammation of the prostate caused by non-bacterial pathogenic microorganisms or non-infectious factors. At present, the etiology of chronic non-bacterial prostatitis is not clear clinically, but it is generally believed that it may be related to factors such as trauma, infection, abnormal urination function, neuropsychological factors, sex hormones, immune function, and oxidative stress. In current medical research, animal models play an important role, and constructing a rat model of chronic non-bacterial prostatitis is of great significance for the mechanism of action and drug research of chronic non-bacterial prostatitis.

[0003] Currently, the construction of a rat model of chronic non-bacterial prostatitis is mainly induced by chemical agents or biological agents. The chemical reagent induction method uses methods such as local injection of carrageenan into the prostate, local injection of Xiaozhiling into the prostate, local injection of glycerol into the prostate, local injection of formaldehyde-croton oil into the prostate, and local injection of 2% agarose into the prostate. The biological agent induction method uses methods such as preparing a rat model with male and female hormones and rat prostate protein extract supplemented with an adjuvant. For the above-mentioned modeling methods, whether it is the induction method of chemical agents or biological agents, the rat prostate needs to be punctured and injected, which is extremely easy to turn into bacterial prostatitis, resulting in modeling failure or a decrease in the modeling success rate. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a non-invasive modeling device for a rat model of chronic non-bacterial prostatitis.

During the entire modeling process, there is no trauma to the rat prostate tissue, avoiding the problem of introducing bacteria during the injection and puncture process, which may lead to modeling failure or a low success rate. This device provides a new means for modeling a rat model of chronic non-bacterial prostatitis.
