Abstract

1475901 Intravenous catheter assembly TECHNOLOGICAL SUPPLY SA 29 May 1974 [11 Oct 1973] 23311/74 Heading A5R An intravenous catheter assembly comprises a catheter tube 1 made of a silicone elastomer which is too flexible and soft to be pushed into a vein,-and a rod 5 within the tube, the rod being sufficiently rigid to enable the catheter tube to be pushed into a vein, the catheter tube consisting of a silicone elastomer and the rod being a plastics rod having on its surface microasperities which maintain the inner surface of the tube spaced from the body of the rod, which microasperities are provided by a film of variable thickness covering the rod. The rod is preferably of Delrin (registered Trade Mark) which is sprayed with Teflon (registered Trade Mark) in the form of a liquid freon-polytetrafluoroethylene aerosol to form the surface film 6. The tube 5 is closed at its distal end and has lateral apertures 2, 3 which permit the flow of perfusion liquid into the vein. A base 4 of rigid plastics material may be integral with the silicone tube or detachable to allow removal of a puncture needle, used to produce the incision for entry of the catheter tube, from the catheter tube. The rod may be fastened to a plug at its proximal end, and the plug may be locked onto the base 4 of tube 1.
