Potential applications of silicone oil in the medical field
Silicone oil has shown extensive potential in the medical field due to its excellent physiological inertness, low toxicity, chemical stability, and lubricity. From basic materials to high-end medical devices, silicone oil is gradually penetrating into various links of the medical industry chain, promoting technological innovation and upgrading clinical demand. The following analysis will be conducted from three dimensions: basic applications, high-end equipment, and innovation directions.


1、 Application of Silicone Oil in Basic Medical Materials
Medical lubricants and isolation agents
Mechanism of action: Silicone oil, as a lubricant, can reduce friction between medical devices and human tissues, thereby lowering the risk of trauma; As an isolation agent, it can prevent material adhesion (such as the internal coating of plasma bags and infusion bags).
Clinical case:
After coating silicone oil on the surface of a certain brand of urinary catheter, the patient's urethral irritation response decreased by 60%, and the retention time was extended to 7 days (traditional catheters only take 3 days).
After treatment with silicone oil on the inner wall of the plasma bag, the red blood cell destruction rate decreased from 5% to 0.8%, significantly improving the quality of blood preservation.
Drug carriers and sustained-release systems
Technical path: Chemical modification (such as introducing carboxyl and amino groups) is used to endow silicone oil with drug loading capacity, or to prepare sustained-release microspheres by compounding with polymers.
Research progress:
Nanoparticles containing silicone oil anticancer drug complexes (with a particle size of 100nm) have a 3-fold increase in enrichment efficiency in tumor tissues and an extended half-life of 48 hours.
Silicone oil based ophthalmic gel is used for glaucoma treatment. The drug release cycle reaches 30 days, and the frequency of drug use for patients decreases from 4 times a day to 1 time a week.
