Abstract

1335396 Valves BIO-MEDICAL SCIENCES Inc 21 Oct 1970 11519/71 Divided out of 1335395 Heading F2V The subject-matter of this Specification is included in the Specification 1,335,395 but the claims relate to a fluid flow regulator comprising a compressible fluid flow conduit 22 and a pair of fluid flow control assemblies 12 and 14 spaced apart along the conduit and each including a valve member 40, 34 operable to compress the conduit and being adjustable to selectively vary the degree of compression of the conduit; a clamp member 26 operable to collapse and thus expel fluid from the portion of the conduit between the control assemblies. The furthest upstream assembly 12 is provided with calibrations whereby the flow rate can be set. A portion 52 of the wall of the conduit is of reduced thickness and will expand, if there is any blockage of the conduit, to indicate such blockage.
