Area of Science:

  • Biomedical Engineering
  • Medical Devices
  • Drug Delivery Systems

Background:

  • Traditional infusion pumps can be cumbersome for ambulatory patients.
  • Existing small infusion systems may lack sophisticated control features.
  • Need for convenient and portable drug delivery solutions in healthcare.

Purpose of the Study:

  • To describe a novel, miniature, wrist-worn infusion pump.
  • To evaluate its efficacy and usability for patient-controlled analgesia (PCA).
  • To explore its potential applications in ambulatory settings.

Main Methods:

  • Development of an electrochemically driven pump utilizing gas generation for propulsion.
  • Implementation of a reservoir compression mechanism for predictable infusion rates.
