摘要：

The Erlanger silver catheter consists of a thermoplastic polgurethane elastomer (TPU). To achieve an antimicrobial effect, silver particles at a concentration of 0.5-1.0% by weight are incorporated into the basic material. The good mechanical properties were shown to remain present after the incorporation of the silver, er. The characteristic mechanical data of blends made of a soft and a hard TPU type approximated closely to a linear relationship with the ratio of the mixture. The buckling stability of catheters as a function of their cross section could be described by Euler's formula. This enables the buckling stability to be calculated when material constants and catheter geometry are known.
