Abstract

The equipment automatically monitors a continuous perfusion operation. Immediately adjacent to the perfusion tube (4) it has a detector (8a, 8b). In the absence of liquid from the tube, this generates a signal operating an alarm and also a mechanism (11) shutting off the tube down-stream of the detector. The latter can comprise a member (11) thrust against the flexible tube, and squeezing it against a rigid stop (6). The member can be mounted on a spring tappet, normally held in the armed position clear of the tube by a trigger.
