DETECTOR SYSTEM

摘要

A detector system for identifying the engagement of a first tube in a second tube, said detector system comprising a connector fixable to an end of said first tube and insertable into said second tube, said connector having an internal channel allowing liquid to flow from said first tube into said second tube when the connector is in place between the first and second tubes, said internal channel being shaped so as to create a backpressure of liquid flowing in said first tube, said internal channel being crossed by a transverse channel which opens to at least one side of the connector, sealing means arranged on either side of all openings of the transverse channel, and arranged to seal against the inner surface of the second tube when the first tube is fully engaged therein, and a sensor such as a pressure switch arranged to detect a reduction in pressure of liquid flowing from the first tube through the connector into the second tube; whereby liquid can flow out through the transverse channel when the connector is not engaged in the second tube, so as to reduce said backpressure of liquid. The system is useful for example in monitoring the integrity of connections used in machines for washing endoscope tubes.
