简介

对于医疗药物给药设备而言,如输液泵或胰岛素泵,精确的剂量至关重要。需要对给药电机进行药物剂量测量和精确控制。电机通常为三相 BLDC(无刷直流)型,功率为几瓦(例如使用 12V)。对于流量传感,可使用工厂校准传感器或定制传感器。同时可通过蓝牙通信,为智能手机提供最新的图形用户界面和附加接口(如以太网或医学级隔离 USB)。一些终端产品可能还需要不间断电源(例如使用锂离子电池)。

此设计采用两个 MCU 的组合,其中包括最新的 RA6M3(用于电机控制和传感器测量)和 RX23W(用于低功耗蓝牙 (LE) 5 通信)。它还包括电源和模拟器件,如 DC/DC 稳压器、锂离子电池充电器、MOSFET 桥式驱动器和工厂校准流量传感器。

系统优势:

  • 支持两种泵类型:输液泵和胰岛素泵
  • 无刷直流电机或永磁同步电机的电机控制,带有模拟或霍尔传感器/编码器,可选档位(也具有高传动比)
  • 流量测量:集成传感器或使用集成有AFE的MCU进行用户定制传感器设置
  • 通信:低功耗蓝牙 5、Wi-Fi、以太网(例如,用于输液泵)和多个串行接口,用于可选的 NB-IoT、独立的USB I/F
  • HMI: LCD(用于输液泵)和触摸和/或手势控制,确保更好的无菌环境
  • 可选电池管理(如 2 块锂离子电池不间断供电)
