Abstract
Abstract A device for controlling the flow of fluid through a resilient, flexible tube for particular use in single use surgical apparatus, having a housing surrounding the tube, an aperture in the side wall of the housing, and a manually or mechanically actuated lever that extends through the aperture in the housing and when actuated compresses the tube at a location adjacent to and in a direction toward the aperture in the side wall of the housing to provide an exact and variable adjustment of the flow rate of liquids through the tube.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
195 words
In a device for controlling the flow of fluid thRough a flexible tube having a longitudinally extending hollow body with longitudinally opposed apertured walls for accommodating the tube, the body having a transverse apertured wall and tube engaging means operable through the aperture of said transverse wall for compressing a portion of the tube and thereby controlling the flow of fluid through the tube, the improvement wherein said tube engaging means comprises a lever extending through the aperture of the transverse wall and mounted for pivotable movement with respect to said aperture, said lever having an arm portion located outside of the body for contact by the operator and a looped portion located within the body, said looped portion encircling the periphery of the tube within the body and having a section on the far side of the tube from the lever arm portion lying opposite the aperture in the transverse wall, so that when pressure is applied to the arm portion of the lever to pivot it towards the body, the said section of the looped portion compresses the tube at a location adjacent to and in a single direction toward the transverse aperture.

Claim 3
Dependent Claim
22 words
The device of claim 1, including arm retaining means slidably mounted on the body for holding the lever in a fixed position.
