1. A medical device comprising:
an access port locater configured to locate a subcutaneous access port located beneath a skin surface of a host, the access port locater including:
at least one annular ring forming an aperture, the at least one annular ring having a longitudinal ring length disposed between first and second opposing ends and a longitudinal axis (LA) extending along the longitudinal ring length, the at least one annular ring positionable on the skin surface of the host with the first end of the at least one annular ring in contact with the skin surface and the longitudinal axis (LA) of the at least one annular ring substantially perpendicular to the skin surface;
at least one stabilizing flange configured to stabilize the access port locater on the skin surface, the at least one stabilizing flange extending laterally from the longitudinal ring length of the at least one annular ring;
at least one needle guard configured to shield a hand of a user of the access port locater when the hand is positioned on the at least one stabilizing flange; and
a membrane removably adhesively bonded to the at least one annular ring to partially or fully cover the aperture; wherein the membrane comprises an antimicrobial coating and is configured to be adhesively bonded to at least part of the skin surface of the host after a needle is withdrawn;
wherein a first end region at the first end of the at least one annular ring forms an annular protrusion relative to the at least one stabilizing flange which is arranged to provide a pressure concentration ridge to press into the skin surface; and the annular protrusion is disposed adjacent the aperture; and
wherein the access port locater is formed of a magnetic material and the access port is also formed of a magnetic material, wherein the access port locater being magnetically attracted to the access port.
