    • Rotation of a rotatalbe assembly of a medical pumping apparatus such as a pump rotor of a rotary peristaltic pump is monitored via electromagnetic radiation (e.g., infrared radiation). The rotatable assembly is formed such that it has portions that are reflective and non-reflective with respect to the electromagnetic radiation. A electromagnetic radiation emitter-detector pair is positioned such that as the rotatable assembly rotates, the reflective and non-reflective portions alternately pass through the electromagnetic radiation emitted by the emitter. The detector receives electromagnetic radiation reflected by the reflective portions, but the non-reflective portions abosorb or disperse the radiation such that it is not received by the detector. An output circuit provides a signal indicating the position of the rotatable assembly as a function of the electromagnetic radiation received by the detector.
    • 通过电磁辐射(例如,红外辐射)来监测旋转蠕动泵的医疗泵送装置如旋转泵的转子组件的旋转。 可旋转组件形成为具有相对于电磁辐射具有反射性和非反射性的部分。 电磁辐射发射器 - 检测器对定位成使得当可旋转组件旋转时,反射和非反射部分交替地穿过由发射器发射的电磁辐射。 检测器接收由反射部分反射的电磁辐射,但是非反射部分吸收或分散辐射使其不被检测器接收。 输出电路提供指示可旋转组件的位置的信号作为由检测器接收的电磁辐射的函数。

    • A rotary type of peristaltic pump having the rotor member mounted on one side thereof and including a swing arm rotatably mounted along the side of the peristaltic pump such that the swing arm is movable between a fluid delivery set loading open position and a closed position which automatically aligns and stretches a portion of the fluid delivery set around the rotor member to ensure that the fluid delivery set is properly aligned about the rotor member of the peristaltic pump. A charger unit assembly is disclosed which is particularly adapted to receive the peristaltic pump thereon for charging the batteries of the peristaltic pump; to provide power to the peristaltic pump and for mounting the peristaltic pump on a support pole. The peristaltic pump also includes drip chamber yoke assembly consisting of a pair of outwardly extending members which receive the drip chamber of the fluid delivery set therein. These members are spaced apart a predetermined distance so that if the length of the drip chamber is less than the predetermined distance, the drip chamber will be supported by the top member. If the length of the drip chamber is greater than the predetermined distance, the drip chamber will be supported by the bottom member.
    • 一种旋转式蠕动泵,其旋转构件安装在其一侧上并且包括可沿着蠕动泵的侧面可旋转地安装的摆臂,使得摆臂可在流体输送装置打开位置和闭合位置之间移动,该位置自动 将流体输送组件的一部分对准和拉伸在转子构件周围,以确保流体输送装置适当地围绕蠕动泵的转子构件对准。 公开了一种充电器单元组件,其特别适用于在其上容纳蠕动泵,用于对蠕动泵的电池充电; 为蠕动泵提供动力,并将蠕动泵安装在支撑杆上。 蠕动泵还包括由一对向外延伸的构件组成的滴水池轭组件,其接纳流体输送组件的滴注室。 这些构件间隔开预定距离,使得如果滴水室的长度小于预定距离,则滴水室将被顶部构件支撑。 如果滴水室的长度大于预定距离,滴水室将由底部构件支撑。
