In medicine, a port (or portacath) is a small medical appliance that is installed beneath the skin. A catheter connects the port to a vein. Under the skin, the port has a septum through which drugs can be injected and blood samples can be drawn many times, usually with less discomfort for the patient than a more typical “needle stick”.
Ports are used mostly to treat hematology and oncology patients, but recently ports have been adapted also for hemodialysis patients. (And cystic fibrosis)
The port is usually inserted in the upper chest, just below the clavicle or collar bone, leaving the patient’s hands free.
