Implantable port catheter systems are becoming increasingly important, as they often permit out-patient treatment for many indications that would otherwise require hospitalization. Moreover, they also increase the safety/reliability of infusion therapy in critical inpatients. For a variety of reasons, the materials used so far, i.e. steel, titanium and various plastics have not been completely satisfactory. The main disadvantage of metallic systems is the formation of artefacts in tomographic images, while the shortcomings of plastics are mechanical, e.g. chip formation and early membrane failure. Against this background, a port catheter system made of alumina ceramic, which is largely free of the disadvantages of the other materials, was developed. The expected advantages in terms of complication rate and radiological artefacts, were fully confirmed by the evaluation of 160 monitored patients.
植入式端口导管系统正变得越来越重要，因为它们常常允许对许多原本需要住院治疗的病症进行门诊治疗。此外，它们还提高了重症住院患者输液治疗的安全性/可靠性。由于各种原因，迄今为止所使用的材料，即钢、钛和各种塑料，都不尽人意。金属系统的主要缺点是在断层图像中会形成伪影，而塑料的缺点则是机械方面的，例如芯片形成和早期膜失效。在此背景下，研发出了一种由氧化铝陶瓷制成的端口导管系统，该系统在很大程度上没有其他材料的缺点。对160名受监测患者的评估充分证实了其在并发症发生率和放射伪影方面预期的优势。
