    • An infusion device with a disposable administration set which is inexpensive to manufacture which set can be slidably inserted and removed from a housing, and which is programmable, is provided. In the preferred embodiment of the present invention the disposable administration set has a plurality of elongated cam followers connected to a plate assembly, wherein the cam followers are displaced in a predetermined sequence and forced against a delivery tube by cam means driven by rotary drive means. The disposable administration set is injection molded as a single integral piece. The disposable administration set includes adjustment spacers disposed between the plate assembly and the cam followers which adjust the distance between them to keep the device accurate. In the preferred embodiment of the present invention the cam means are configured to provide fluid delivery at a consistent and uniform rate. A bar code label as provided on the disposable administration set and a bar coder reader is provided on the housing of the infusion device for reading fluid delivery parameters when the administration set is slidably inserted into the housing.
    • 提供了一种具有一次性给药装置的输液装置,其制造成本低廉,可将其从壳体可滑动地插入和移除并且是可编程的。 在本发明的优选实施例中,一次性给药组具有连接到板组件的多个细长凸轮从动件,其中凸轮从动件以预定顺序移位,并且通过由旋转驱动装置驱动的凸轮装置而被迫抵靠输送管。 一次性管理组件被注塑成单个整体件。 一次性给药组包括设置在板组件和凸轮从动件之间的调节间隔件,其调节它们之间的距离以保持装置准确。 在本发明的优选实施例中,凸轮装置构造成以一致且均匀的速率提供流体输送。 在一次性管理装置上设置的条形码标签和条形码读取器设置在输注装置的壳体上,用于当管理装置可滑动地插入到外壳中时读取流体输送参数。
