    • A system for controlled delivery of medicinal fluid includes a fluid pathway assembly defining a fluid pathway and including means for calculating a first calculated fluid flow rate using gas laws. The fluid pathway assembly has an inline flow sensor element received within the fluid pathway movable in response to fluid flowing in the fluid pathway. A flow control device is removably attached to the fluid pathway assembly and has a sensor for sensing a position of the inline flow sensor element in the fluid pathway, the position of the inline flow sensor element being representative of a second calculated fluid flow rate. The fluid pathway assembly includes a variable flow resistor adjustable to regulate a rate of fluid flow in the fluid pathway assembly. A drive mechanism attached to the flow control device is operably coupled to the variable flow resistor when the flow control device is attached to the fluid pathway assembly. The variable flow resistor is adjustable by the drive mechanism to achieve a target flow rate when the first calculated flow rate and/or the second calculated flow rate differs from the target flow rate.
    • 用于控制输送药液的系统包括限定流体通路的流体通路组件,并且包括用于使用气体定律计算第一计算流体流量的装置。 流体通道组件具有接收在流体通道内的在线流量传感器元件,其可响应于在流体通路中流动的流体而移动。 流量控制装置可移除地附接到流体通路组件,并且具有用于感测流体通道中的在线流量传感器元件的位置的传感器,该在线流量传感器元件的位置代表第二计算的流体流速。 流体通道组件包括可调节流量的可变流量电阻器,以调节流体通道组件中的流体流速。 当流量控制装置附接到流体通路组件时,连接到流量控制装置的驱动机构可操作地耦合到可变流量电阻器。 当第一计算流量和/或第二计算流量与目标流量不同时,可变流量电阻器可由驱动机构调节以实现目标流量。
