Area of Science:

  • Biomedical Engineering
  • Traditional Chinese Medicine
  • Medical Devices

Background:

  • Conventional acupuncture, while widely used in oriental medicine, presents challenges for continuous or intermittent stimulation during daily life.
  • The insertion of needles in traditional acupuncture can cause infection, fear, and pain, limiting patient compliance and accessibility.

Purpose of the Study:

  • To evaluate a novel acupoint stimulation device utilizing focused ultrasound.
  • To assess the efficacy of this device in modulating blood flow, comparing it to traditional acupuncture.

Main Methods:

  • Development of a compact (6 mm diameter) focused ultrasound device for transcutaneous acupoint stimulation.
  • Stimulation of acupoints using the device with adjustable intensity and patterns via driving voltage.
  • Measurement of brachial artery blood flow volume to quantify the physiological response.

Main Results:

  • The focused ultrasound device successfully stimulated acupoints through intact skin.
  • A significant increase in brachial artery blood flow volume was observed, comparable to traditional acupuncture.
  • The non-invasive nature of the device eliminates risks of infection, fear, and pain associated with needle insertion.

Conclusions:

  • The focused ultrasound acupoint stimulation device is a viable, non-invasive alternative to conventional acupuncture.
  • This technology offers a safe and convenient method for acupoint stimulation, potentially enhancing patient comfort and adherence.
  • Further research should explore long-term effects and broader clinical applications of this innovative device.
