APPLICATIONS

摘要

The utilisation of medical devices, such as catheters, can be gready improved by having a hydrophilic coating on the device. The insertion and displacement of urinary or blood catheters is made much easier by adsorption of a film of water by hydrophilic surfaces in contact with the blood or urine, which reduces the friction between the catheter and the vessel walls. In addition, when catheters are used in contact with blood there is always a risk of blood clots forming: hydrophilic coatings are generally considered useful as antithrombogenic coatings.
