A SIMPLE, RELIABLE, ELECTRONIC PNEUMATIC PUMP ACTUATOR

拟议计划的目标是开发一种便携式、 可靠、简单易用的电动气动泵执行器。新的 驱动程序不需要压缩机、调节器、电磁阀、滑动密封件、 或易受机械磨损的类似部件。设计的基础 是一种由电磁直线驱动器驱动的焊接金属波纹管。 执行机构的总偏移量和运动速率。总数 在每个节拍上控制执行器的漂移和移动速率 使用闭环伺服系统来监控波纹管位置和 内部压力。一个以微处理器为基础的数字控制系统将被 设计允许固定费率、自主可变费率、被动 触发或EKG触发操作模式。操作员只是 指定操作条件，同时控制系统保持 所需的设置独立于后负荷或速率更改，并避免 压力变化速度过快，可能导致溶血。新的 驱动程序紧凑和便携；凭借其优雅的机械 简单，它的制造成本可能只有笨重的一小部分 和/或目前可用的机械复杂系统。

The goal of the proposed program is the development of a portable, reliable, and simple-to-use electronic pneumatic pump actuator. The new driver eliminates compressors, regulators, solenoid valves, sliding seals, or similar components subject to mechanical wear. The basis of the design is a welded metal bellows driven by an electromagnetic linear actuator. The total excursion and rate of movement of the actuator. The total excursion and rate of movement of the actuator are controlled on each beat using a closed-loop servo system which monitors the bellows position and internal pressure. A microprocessor-based digital control system is to be designed which will permit fixed rate, autonomous variable rate, passive triggered, or EKG triggered operating modes. The operator merely specifies the operating condition, while the control system maintains then the desired settings independent of afterload or rate changes and avoids excessive rates of change of pressure which can cause hemolysis. The new driver is compact and portable; and by virtue of its elegant mechanical simplicity, it may be manufactured for a fraction of the cost of the bulky and/or mechanically complex systems currently available.
