    • An improved implantable valve accumulator pump for the delivery of medication is disclosed. The implantable pump comprises a pressurized drug reservoir. The medication metering assembly comprises a fixed volume accumulator positioned between a pair of valves. The valves alternately open and close to admit medication from the reservoir into the accumulator and to dispense a precise volume pulse to an outlet catheter. In order to improve the pump's accuracy and to increase pumping volume while optimizing the pump's overall size and energy usage a two way diaphragm accumulator is used. The unit can be externally programmed or can be used in a fixed rate configuration that is never programmed but set at the factory or in the current programmable configuration.
    • 公开了一种用于输送药物的改进的可植入阀蓄能器泵。 可植入泵包括加压药物储存器。 药物计量组件包括位于一对阀之间的固定容积蓄积器。 阀交替地打开和关闭,以将药物从储存器进入蓄能器并且将精确的体积脉冲分配给出口导管。 为了提高泵的精度和增加泵送量,同时优化泵的总体尺寸和能量使用,使用双向隔膜蓄能器。 该单元可以进行外部编程,也可以以固定速率配置使用,从未编程,但在出厂时或当前的可编程配置中设置。
