Abstract
A tube clamp for an extracorporeal circulator recognizes various abnormal situations of the tube clamp and notifies a user. The tube clamp has a lid sensor, a tube sensor, and a plunger sensor. In a case where any one of detection of the closure of a lid portion via the lid sensor, detection of the mounting of a tube via the tube sensor, and detection of the movement of a plunger via the plunger sensor is not obtained despite the fact that there is an instruction for blocking the tube, it is determined that the blocking is abnormal. In a case where the three states including the closed state, the mounting state, and the movement state are detected despite the fact that there is no instruction for blocking the tube, it is determined that the tube is erroneously blocked. Such abnormal situations are notified to a user via an alarm.
