    摘要: A parenteral liquid administration set which is readily changeable between delivering liquid at measured ''''rate'''' through a drip chamber that has a constant liquid level, and delivering liquid from the chamber in a measured ''''volume'''' with a progressively lowering liquid level. A valve system on a top of an enlarged semi-rigid measuring chamber functions to selectively change between ''''rate'''' and ''''volume'''' delivery. In one version there is also a secondary drip chamber below the enlarged semirigid measuring chamber so the set can simultaneously indicate ''''rate'''' and ''''volume'''' delivery.
