9 . A method of securing a catheter hub, the method comprising:
locking the catheter hub in a housing that comprises a lock mechanism, wherein the lock mechanism comprises one or more lock disc cams comprising one or more openings, each lock disc cam of the one or more lock disc cams comprising a cam feature,
wherein removal of the catheter hub that is locked in the housing requires unlocking the lock mechanism of the housing.
10 . The method of claim 9 , wherein the lock mechanism comprises a cylinder, and wherein unlocking the lock mechanism of the housing comprises rotating the cylinder.
11 . The method of claim 9 , wherein the housing comprises one or more interlocking tabs, each interlocking tab of the one or more interlocking tabs having a hook feature.
12 . The method of claim 9 , further comprising inserting a key into the housing to unlock the housing, wherein the key comprises a plurality of protrusions radially extending from a shank of the key.
13 . The method of claim 9 , wherein locking the catheter hub in the housing comprises:
placing the catheter hub in the housing when housing is open; and
closing the housing.
14 . The method of claim 9 , wherein the housing is a clamshell housing comprising a body and a cover that are pivotably connected via a hinge.
15 . The method of claim 9 , further comprising fitting a key with the lock mechanism of the housing.
16 . The method of claim 15 , wherein the fitting the lock mechanism of the housing with the key prevents other keys that are configured differently than the key from being able to open the locked housing.
17 . The method of claim 15 , wherein the housing comprises a shield protruding inside the housing and arranged to protect the key from damaging the catheter hub.
