Description

Kunststoff für blutneutrale Verwendung i3ei der Snfertigullg von Bluttransfusionsgeräten, Blutkanülen, Kolben, Spritzen, Schläuchen und Blutaufbewahrungsgefäßen ist man bestrebt, das ursprünglich verwandte Material, nämlich Glas, Porzellan oder Metall, durch Stoffe zu ersetzen, die sich den Thrombozyten gegenüber neutral verhalten, jedenfalls die Blutgerinnung nicht fördern. Hierzu haben sich einige Kunstharze als hrauchbar erwiesen. Indessen krankt die Fertigung solcher Geräte an gewissen Werkstoffmängeln.Plastic for blood-neutral use i3in the preparation of blood transfusion machines, Blood cannulas, plungers, syringes, tubes and blood storage vessels strive to the originally used material, namely glass, porcelain or metal To replace substances that behave neutrally towards the platelets, at least do not promote blood clotting. For this purpose, some synthetic resins have proven to be useful proven. However, the manufacture of such devices suffers from certain material defects.

Außerdem sind die Kunstharze ziemlich spröde und bei der Notwendigkeit der laufenden Reinigung und Sterilisierung wenig haltbar.In addition, the synthetic resins are quite brittle and if necessary not very durable after ongoing cleaning and sterilization.

Die Erfindung geht nun von der Erfahrung aus, daß man bereits früher Glasgefäße zum Auffangen von F;,lut dann mit Erfolg verwenden konnte, wenn seine innere Oherfläche mit Paraffin benetzt wurde Solche Praktiken sind sogar sehr gebräuchlich. Wir haben tatsächlich in dem Paraffin bis heute noch den blutneutralsten der hier einsetzbaren Stoffe. The invention is based on experience that one already earlier Glass vessels to collect F;, lut could then use successfully if his inner surface was wetted with paraffin. Such practices are very common. In fact, to this day we still have the most blood-neutral paraffin here usable substances.

Gegenstand der Erfindung ist nun die Verwendung hochpolymerer Paraffine als Werkstoff für die Fertigung von Bluttransfusionsgefäßen, Behältern. Kanülen, Schläuchen, Spritzenkolben und dahin gehörenden Geräten aller Art. Der zur Zeit hierfür brauchbare Kunststoff als Vertreter hochpolymerer Paraffine ist das Polyäthylen, in welchem eine Äthylengruppe zu etwa 2000 Kettengliedern polymer verbunden ist, so daß ein hochmolekularer Kohlenwasserstoff entsteht, der wesentliche Paraffineigenschaften mit Kunststoffeigenschaften verbindet. Die erwähnten medizinischen Geräte zur Verwendung im Blutkontakt können nach den bekannten Methoden des Spritzgußverfahrens sehr ökonomisch hergestellt werden. The invention now relates to the use of high-polymer paraffins as a material for the manufacture of blood transfusion vessels and containers. Cannulas, Hoses, syringe plungers and associated devices of all kinds. The one at the moment A plastic that can be used for this purpose as a representative of high-polymer paraffins is polyethylene, in which an ethylene group is polymerically linked to about 2000 chain links, so that a high molecular weight hydrocarbon arises, the essential paraffin properties connects with plastic properties. The mentioned medical devices for use in blood contact can be made according to the known methods of the injection molding process can be produced very economically.

Zur Weichstellung des Materials für die Fertigung von Schläuchen. Pelotten, weichen Folien usw. wird erfindungsgemäß die Verwendung eines Kohlenwasserstoffes mit entsprechenden Eigenschaften, z. B. Paraffinöl, vorgeschlagen. For softening the material for the manufacture of hoses. Pads, soft foils, etc., according to the invention, the use of a hydrocarbon with appropriate properties, e.g. B. paraffin oil suggested.

PATENTAN5PRCHE: I. Kunststoff für blutneutrale Verwendung gekennzeichnet durch die Verwendung von hochpolymeren Kohlenwasserstoffen, insbesondere Polyäthylen als Werkstoff für Bluttransfusionsgeräte, Blutbehältnisse, Kanülen (auch stahlarmiert) Schläuche für solche und verwandte medizinische Zwecke, Spritzenkolben usw. PATENT APPROVAL: I. Plastic marked for blood-neutral use through the use of high polymer hydrocarbons, especially polyethylene as a material for blood transfusion devices, blood containers, cannulas (also steel armored) Tubing for such and related medical purposes, syringe plungers, etc.
