port
This is an implated access device which allows professional carers to draw blood and make intravenous (or intra-arterial) injections into a patient in an easier way without having to locate and insert a canulla into a new vessel. Some ports are connected for intrathecal, intraperitoneal or intracavitary injections. These devices are expensive and are not free of problems, they should not be implated without good indications. Normally implantation is performed by a surgeon with experience in this technique, in a operational theatre under local anaesthetic.
