    摘要： An interlock, latching and retaining mechanism for use in an infusion system, embodying a latch arm mounted to a rotatable shaft having a plurality of cams and gears attached thereto, a rectangular faceplate with a plurality of apertures formed therethrough, and a clamp. Rotating the latch arm functions to engage fluid monitoring, flow control and pumping structure of the infusion system with a pumping segment for control of fluid flow through the segment and also causes the clamp to hold the pumping segment in a required position. In another aspect, rotation of the latch arm additionally causes an air-in-line sensor to rotate into position on the pumping segment.

    摘要： A multi-channel ink supply pump includes a pump shaft with four associated rollers and a cam shaft with four cams evenly spaced longitudinally along the cam shaft. Four tube pinching arms are each hinged at one end to a fixed point. The free ends of the tube pinching arms are spring-biased toward the pump shaft. A first motor is configured through gears to rotate the pump shaft. A second motor is configured through gears to rotate the cam shaft. The pump shaft and the cam shaft are not simultaneously rotated. Tubes carrying ink run underneath the pump shaft and rollers, between the rollers and the tube pinching arms. The cam shaft is normally positioned to counteract the spring bias in all of the tube pinching arms, retracting all of the tube pinching arms away from the pump shaft. The cams are individually oriented to different positions so that one full rotation of the cam shaft counteracts the spring bias for three of the four tube pinching arms at any given time, allowing each tube pinching arm in succession to temporarily rotate toward the pump shaft. In addition all four tube pinching arms are simultaneously allowed to temporarily rotate toward the pump shaft during the one full rotation of the cam shaft.

    摘要翻译： 多通道供墨泵包括具有四个相关联的辊的泵轴和具有四个凸轮的凸轮轴，凸轮轴沿凸轮轴纵向均匀分布。 四个管夹臂各自在一端铰接到固定点。 管夹臂的自由端朝向泵轴弹簧偏置。 第一马达通过齿轮配置以使泵轴旋转。 第二马达通过齿轮配置以旋转凸轮轴。 泵轴和凸轮轴不同时旋转。 带有墨水的管子运行在泵轴和滚子之间，辊与管夹紧臂之间。 凸轮轴通常定位成抵消所有管夹紧臂中的弹簧偏压，使所有管夹紧臂从泵轴回缩。 凸轮单独地定位到不同的位置，使得凸轮轴的一个完整的旋转在任何给定的时间抵消四个管夹紧臂中的三个的弹簧偏压，允许每个管夹紧臂相对于泵轴暂时旋转。 此外，在凸轮轴的一个完整旋转期间，所有四个管夹持臂同时被允许临时地朝向泵轴转动。
