Classification: CPC A | IPC A

Claim 17:
18. A spike-locking mechanism configured to be received within a spike port of a medical device and resist extraction of a medical spike when received within the spike port, the spike-locking mechanism being switchable from an unlocking state in which insertion of the medical spike into the spike port is allowed, and a locking state in which extraction of the medical spike from the spike port is resisted, the locking state is automatically activated upon initiating extraction of the medical spike out of the spike port, to thereby lock the medical spike inside the spike port, wherein said spike-locking mechanism comprises a spike-locking element having an outer rigid portion and a movable portion extending inwardly from the outer rigid portion towards a port longitudinal axis of the spike port and away from a proximal port inlet of the spike port, said movable portion of the spike-locking element comprising:
at least one first inwardly projecting element inclined with respective at least one first element angle defined with respect to a proximal portion of the port longitudinal axis and having respective at least one first element distal portion that contacts an outer surface of the medical spike when located in the spike port; and
at least one second projecting element inclined with respective at least one second element angle defined with respect to the proximal portion of the port longitudinal axis, said at least one second element angle being greater than said at least one first element angle, said at least one second projecting element having respective at least one second element distal edge configured to contact the outer surface of the medical spike.
