Abstract: Valving configurations between the valve seat in a cassette and the valve members in a controller used to limit the flow rate of an intravenous solution to a patient. The configurations minimize the criticality of the alignment between the components. The cassette forms part of the flow path of the solution on its way to the recipient. The controller's valve member may stretch a membrane in the cassette and cause it to contact a flat surface surrounding the opening through which the fluid must flow. Alternately, the end of the valve member may be appreciably smaller than the opening, pass through it, and stretch the membrane until the latter contacts all of the opening's edge. The membrane meeting the edge of the opening in a closed loop prevents the flow of fluid through it. As a further possibility, the valve member may place the membrane in contact with one or more edges provided between two segments of a straight channel through which the solution flows.
