✦ Synopsis

The patient suffers a lot when cystoscopes or catheters are inserted into the urinary system. In order to lower friction whilst being non-poisonous, nonfimgoid, and meeting other medical requirements, a new bionic medical lubricant has been synthesised. In tests imitating the friction condition between skin and plastic apparatus, eel fish synovia, white oil, glycerol, polyethylene glycol in aqueous solution, Tween-80, a proprietary medical lubricant, and the candidatefluid were tested. The results of these tests demonstrated that the synthesised lubricant pe$orms best, with eel fish synovia second, and glycerol last.

The test fluid has been trialled in some key hospitals (Shanghai, Beijing, Guangzhou, and Shijia Zhuang), and the results showed that about 95% of patients experienced no pain, and about 5% had a slight feeling, with no reported discomfort. The candidate bionic medical lubricant is in use by doctors in medical practice.
