Infusion Pump

Overview

An infusion pump is a medical device that delivers fluids, such as medications and nutrients, into a patient's body in a controlled manner. It regulates the infusion drops or flow rate to ensure even distribution and accurate, safe delivery of the drug.

This infusion pump design offers high stability and accuracy to guarantee effective medical therapy and safety, with a long battery life for continuous infusion.

System Benefits​:

  • High-performance 100MHz Arm® Cortex®-M33 core MCU with rich connectivity, ideal for IoT applications.
  • Ultra-low power Wi-Fi SoC for wireless communication, enhancing operational life and power efficiency.
  • High voltage GreenPAK™ programmable mixed-signal matrix supports the stepper motor with full-stepping, half-stepping, and microstepping for precision control and smooth operation.
  • High-resolution position sensor IC and high-performance op amp ensure system accuracy.
