Abstract

An apparatus and method for preventing free flow through an infusion set utilizes an occluder (104) disposed within the infusion set to selectively prevent flow therethrough. The occluder may be responsive to a pressure differential within the infusion set or may respond to compression of the infusion set. When a pair of occluders (504, 508) are used in sequence, an in-line pump may be formed.
