发明名称 Venous catheter device
摘要 A venous catheter device including a plurality of independent and noncommunicating fluid conveying lumens housed within or formed in a single catheter. One end of each lumen is adapted to be connected to a different fluid source, such as an intravenous (IV) drug infusion or feeder device, a syringe, etc., or to a central venous pressure (CVP) measuring device. The other end of each lumen exits at or proximate to the catheter terminus which, in turn, is adapted to be positioned within a vein. A hollow needle slidably receives the catheter terminus and is adapted for vein penetration and catheter positioning within the penetrated vein. Alternatively, the catheter can be used without a needle in which case a vein is directly exposed and partially transected allowing direct insertion of the catheter.
