AI Technical Summary

Technical Problem

When obtaining prostatic fluid under non-invasive conditions, the urethra is easily contaminated by bacteria and white blood cells, leading to false positive or false negative results in the diagnosis of prostatitis subtypes. In addition, the operation is complicated and has a low application rate among doctors.

Method used

Organosilicon quaternary ammonium salts are used to prepare urethral biocompatible material membranes. These membranes can be self-assembled to form nanoscale or molecular-level tubular membranes, which can prevent or destroy bacterial biofilms, isolate bacteria and leukocytes, and improve the method of collecting prostatic fluid.

Benefits of technology

It effectively avoids urethral contamination, improves the accuracy of prostatitis classification diagnosis, simplifies operation, and increases the application rate among doctors.

Abstract

The application discloses application of a silicone quaternary ammonium salt in preparation of a prostatitis typing diagnosis medical material, and the silicone quaternary ammonium salt can improve typing diagnosis of prostatitis, forms a biocompatible film of a molecular level or a nanotube in a urethra, prevents or destroys a bacterial biofilm, and the prostatic fluid flows out through the tube and is not polluted by bacteria and leukocytes, thereby improving a typing diagnosis rate, providing a basis for prostatitis treatment, and providing a new method for typing diagnosis of prostatitis.
