Anti-bacterial hydrophilic urethral catheter

Abstract

The invention discloses an anti-bacterial hydrophilic urethral catheter which comprises a urethral catheter body and a coating coated on the surface of the urethral catheter body. The urethral catheter body is prepared from a fluorine-silicon material copolymer, polyurethane and 1-(3-triethoxysilylpropyl)-1H-pyrrole-2,5-diketone modified fullerene, wherein the coating on the surface of the urethral catheter body is prepared from 3-(2-hydroxyethyl)-1-[[3-(2-hydroxyethyl)-2-oxopyrrolidin-1-yl]methyl]pyrrolidin-2-one, Bis[2-(3,4-epoxycyclohexyl)ethyl]tetramethyldisiloxane and polylactic acid through a chemical reaction. The prepared anti-bacterial hydrophilic urethral catheter is excellent in comprehensive performance, has a continuous anti-bacterial effect, is excellent in surface hydrophilic lubrication, flexibility and comfort, and is easy to insert.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a medical catheter and a preparation method thereof. Background technique

[0002] In recent years, general paralysis or hemiplegia caused by brain diseases such as stroke or spinal injury, non-neurogenic bladder diseases such as obstruction caused by prostatic hypertrophy, urethral stricture or postoperative urinary retention, and spina bifida or multiple The number of patients with neurogenic bladder diseases such as sexual sclerosis is increasing year by year due to reasons such as an increase in the elderly population and an increase in traffic accidents and industrial accidents. These patients need continuous urinary catheterization to empty their bladders during treatment, and medical catheters are needed during catheterization. Medical catheters are a safe, effective, and compatible tool for diagnosis and treatment. The application is becoming more and more extens...
