Tube for medical purposes

摘要

The invention relates to a PVC-free tube (100) for medical purposes, comprising three superimposed layers (101, 102, 103). Each of said layers contains a polyolefin while the inner layer (102) additionally contains at least 60 percent of a thermoplastic elastomer. The invention further relates to a tube system encompassing several inventive tubes which are joined together via connectors. The disclosed tube allows the flow rate loss, e.g. in an extracorporeal circulatory system, to be kept below 15 percent, preferably below 10 percent.
