Syringe adapter with compound motion disengagement

A syringe adapter assembly comprising:

• a syringe adapter comprising:
• an outer housing having a distal end, a proximal end, and a generally cylindrical sidewall extending between the distal end and the proximal end;
• an inner member comprising a body rotatably inserted within the outer housing and a connector extending from the body configured to connect the adapter to a fluid container, the inner member defining a removal interface;
• a first locking arrangement engageable with the body of the inner member and configured to restrict the inner member from rotating relative to the housing in a first direction;
• and
• a second locking arrangement engageable with the body of the inner member and configured to restrict the inner member from rotating relative to the housing in both the first direction and a second direction,
• wherein the adapter is transitionable between:
• a disengaged state, in which the first locking arrangement and the second locking arrangement are not engaged with the inner member;
• a partially engaged state in which the first locking arrangement engages the inner member;
• and a fully engaged state in which the second locking arrangement engages the inner member;
• and
• a removal tool configured to engage the removal interface of the inner member to prevent rotation of the inner member relative to the outer housing.
