Abstract
A system for securing a blood separator bowl in an autotransfusion machine includes a split ring or collar adapted to grip an enlarged cap on the base of the bowl and a clamp assembly for moving the collar between retracted and expanded positions. In the retracted position, the clamp assembly includes both an overcenter lock system for securing the collar in the retracted position and a backup auxiliary lock in the event of failure. The system further provides for centering the separator bowl on its axis of rotation to prevent undue vibration.
