<p>A flow adjusting tube clamp (14) is used with a chamber (26) in a solution administration device (10). The tube clamp (14) is pivotally mounted to the cap (28) at a second pivot element (36). The tube clamp (14) includes first and second elongated tube passages (54, 56) that overly the cap inlet ports (44, 46) as the clamp is pivoted. The tube passages (54, 56) define varying cross-sectional open areas therethrough. The passages (54, 56) are arcuate so that they continuously overly the inlet ports (44, 46) as the clamp is pivoted. The inlet ports (44, 46) are configured to receive flexible tube portions (20a, 20b) that traverse through the tube passages in the clamp. Each tube passage (54, 56) includes at least one open area (66) and at least one occluding portion (56) to establish and terminate flow therethrough. The clamp (14) is pivotable from a prime position to an intermittent flow position and from an intermittent flow position to a continuous flow position, to effect varying flow conditions.</p> |
