| 摘要 |
<p>The invention provides a flow control system (10) well suited for use in intravenous fluid delivery systems comprising a flow restrictor wafer (36), (122) having one or more flow limiting flow restrictor paths (40), (50) formed thereon. The system provides fixed flow rate control. The system also provides means (90) for selectively orienting at least two flow restrictor paths (128), (130), (132), (134) to the main fluid passage to vary the flow rate.</p> |
