Lochlans Port

the port is completely under the skin. See it in his chest?

Here it is accessed. The black thing is the "grip" on his Huber needle which pokes through the skin into the port

the tube comes from the bottom of the port and is threaded up the chest (inside) to the neck where it goes into the jugular and down into his heart

It stays until it gets clogged or infected or is no longer needed. It must be surgically removed. They sewed a "pocket" in his chest that holds it, made of skin and muscle.
