摘要：
An implantable infusion device includes an outlet and a reservoir. A flow path in fluid communication with the reservoir and the outlet includes a pressure regulator and a flow restrictor. The pressure regulator includes a major chamber and a diaphragm that divides the major chamber into first and second minor chambers. The flow restrictor is in fluid communication with the first and second minor chambers of the pressure regulator and is disposed downstream of the first minor chamber and upstream of the second minor chamber. The device also includes a processor coupled to a flow sensor to detect information regarding flow rate of the fluid downstream of the flow restrictor and a pressure adjustment actuator assembly. The processor provides regulates the flow of the fluid by adjusting the pressure in the first minor chamber relative to pressure in the second minor chamber based on the information from the sensor.
摘要（中）：
植入式输注装置包括出口和储存器。 与储存器和出口流体连通的流路包括压力调节器和限流器。 压力调节器包括主室和隔膜，其将主室分成第一和第二小室。 限流器与压力调节器的第一和第二小室流体连通并且设置在第一小室的下游和第二小室的上游。 该装置还包括耦合到流量传感器的处理器，以检测关于限流器下游的流体的流量的信息和压力调节致动器组件。 处理器基于来自传感器的信息，通过相对于第二小室中的压力调节第一小室中的压力来调节流体的流动。
