Septum: withstands many needle entries.
Choice: port, PICC or external catheter depends on how long and what kind of treatment.
04What happens in the body?
Port
A port is usually placed below the collarbone in a small operation. The chamber has a silicone top that is reached with a special needle. When it is not in use nothing is outside, so daily life such as showering and swimming (if your team agrees) is easier. Ports are chosen for long treatment with breaks.
