ABSTRACT:
A plunger assembly for obstructing the flow of fluid through a flexible tube is provided. The assembly comprises a plunger sleeve member having a first open end and a compression mechanism for selectively contacting and compressing the flexible tube. The compression mechanism has a contacting portion for contacting the flexible tube and an extending portion with the extending portion being slidably receivable within the plunger sleeve member through the first open end of the plunger sleeve member. A spring mechanism is mounted about the extending portion of the compression mechanism and between the contacting portion of the compression mechanism and the first open end of the plunger sleeve member for providing selective movement to the compression mechanism relative to the plunger sleeve member. A sensor mechanism associated with the plunger sleeve and the compression mechanism is provided for translating the displacement of the compression means relative to the plunger sleeve to a measurement of force applied by the compression means to the flexible tube.
