A new method for intermittent administration of i.v. fluids which maintains the advantages of the piggyback system but at a lower cost than the piggyback system is described. The system uses a volume control chamber as a replacement for a minibag or minibottle to deliver doses of different medications. The volume control set, when attached in the prescribed fashion, permits the flow from the primary i.v. solution to resume automatically when the volume control chamber is empty. One large-volume container of i.v. fluid can be used to dilute many doses of different drugs in the volume control chamber rather than one small-volume container per dose. No significant difficulties have been encountered with the mechanics of the system, and nursing response has been favorable.
描述了一种静脉输液间歇性给药的新方法，该方法保留了背负式系统的优点，但成本低于背负式系统。该系统使用容量控制腔代替小袋或小瓶来输送不同药物的剂量。当以规定方式连接时，容量控制装置允许在容量控制腔为空时，主静脉输液溶液自动恢复流动。一大瓶静脉输液可用于在容量控制腔内稀释多剂不同药物，而不是每剂使用一个小容量容器。该系统的机械装置未遇到重大困难，护理反馈良好。
