Abstract
The invention presented is a needle system to access a subcutaneous port primarily for the administration of chemotherapy, designed to protect the health care worker from inadvertent needle injury by isolation of the needle tip within base and tower components. A rotating collar is designed to keep the needle immobile until access of the port is desired when it can be rotated to align a cut out with a corresponding cut out of the tower that houses the needle for advancement of the needle downward into the port. On retraction, the collar can be rotated, locking the needle back into a retracted position within the tower.
