摘要 |
<p>A parenteral liquid administering device includes an enlarged, liquid-holding burette-type chamber for receiving measured aliquots of liquid from a source. The burette has a bottom flow aperture with a valve controlling flow through the aperture. The valve includes a buoyant float ball and a valve seat positioned about the bottom flow aperture to receive the ball, in the absence of sufficient liquid to float it, in air-tight, sealing relation. Apertured retention means are provided surrounding the ball which are proportioned to permit it to float in spaced relation from the valve seat in the presence of liquid passing through the apertured retention means.</p> |
