Kateeterimaterjalide

Kateeterimaterjalid refers to the substances used in the manufacturing of medical catheters. These materials are chosen based on their biocompatibility, flexibility, strength, and ability to be sterilized. Historically, materials like rubber and silk were used, but modern catheters primarily utilize advanced polymers.

Commonly used polymers include silicone, polyurethane, and polyvinyl chloride (PVC). Silicone is favored for its excellent biocompatibility and flexibility, making it suitable for long-term indwelling catheters. Polyurethane offers a good balance of strength and flexibility, often used in urinary catheters. PVC, while less flexible, is a cost-effective option for certain applications. Latex, a natural rubber, is also used but can cause allergic reactions in some individuals.

Beyond basic polymers, specialized coatings are often applied to catheter surfaces. Hydrophilic coatings, for example, become slippery when wet, reducing friction during insertion and minimizing patient discomfort. Antimicrobial coatings are also employed to help prevent catheter-associated infections. The selection of specific materials and coatings depends on the intended use of the catheter, such as urinary drainage, vascular access, or surgical procedures. Research continues to develop novel kateeterimaterjalid with improved properties to enhance patient safety and treatment efficacy.
