Description

An Dichtungsmaterialien für Injektionsspritzen und Pumpen zur Förderung von Blut und anderen Flüssigkeiten für medizinische Zwecke, z. B. in Blutaustauschgeräten, Herz-Lungen-Maschinen, künstlichen Nieren und Vorrichtungen für die Peritonealdialyse werden besondere Anforderungen gestellt. Of sealing materials for injection syringes and pumps for delivery of blood and other fluids for medical purposes, e.g. B. in blood exchange devices, Heart-lung machines, artificial kidneys and peritoneal dialysis devices special requirements are made.

Sie müssen gegen Blut und andere Flüssigkeiten, die in den menschlichen und tierischen Körper eingeführt oder hindurchgeführt werden, ungiftig und indifferent sein und sich für die Sterilisation z. B. mit Äthylenoxyd oder energiereichen Gammastrahlen eignen. Sie dürfen sich beim Gebrauch in den Geräten nicht verformen und nicht kleben. You have to against blood and other fluids that are in human and animal bodies are introduced or passed through, non-toxic and indifferent his and for the sterilization z. B. with ethylene oxide or high-energy gamma rays suitable. They must not deform or stick during use in the devices.

Aufgabe der vorliegenden Erfindung ist es, Dichtungsmaterial, z. B. Dichtungsringe, zu schaffen, welches für die genannten Zwecke elastisch genug ist, sich gegenüber Blut und anderen Flüssigkeiten für medizinische Zwecke indifferent verhält, für die Sterilisation mit Äthylenoxyd oder energiereichen Gammastrahlen geeignet ist, bei der Gebrauchstemperatur gleitfähig bleibt, sich nicht verformt und seine mechanischen Werte beibehält. The object of the present invention is to provide sealing material, e.g. B. sealing rings to create which is elastic enough for the purposes mentioned is indifferent to blood and other fluids for medical purposes behaves, for sterilization with ethylene oxide or high-energy gamma rays is suitable, remains slippery at the usage temperature, does not deform and maintains its mechanical values.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß als Dichtungsmaterial für Injektionsspritzen und Pumpen zur Förderung von Blut und anderen Flüssigkeiten für medizinische Zwecke thermoplastischer Kautschuk verwendet wird, der durch Kopolymerisation von Styrol und Butadien erhalten wird. This object is achieved according to the invention in that as a sealing material for injection syringes and pumps for conveying blood and other liquids for medical purposes thermoplastic rubber is used, which is produced by copolymerization is obtained from styrene and butadiene.

Dieser thermoplastische Kunststoff ist in überraschender Weise und in besonderem Maße geeignet als ideales Dichtungsmaterial für Injektionsspritzen und für Pumpen zur Förderung von Blut und anderen Flüssigkeiten für medizinische Zwecke. This thermoplastic material is surprisingly and Particularly suitable as an ideal sealing material for injection syringes and for pumps for pumping blood and other fluids for medical purposes Purposes.
