Strategic Insights

— 1 min read

CHARMCARE CO., LTD., a cutting-edge South Korean company, has successfully developed a revolutionary blood pressure measurement device. This groundbreaking invention, patented as "Sensor module for measuring blood pressure, and wrist-wearable portable blood pressure measurement device using same," has the potential to revolutionize the field of healthcare. The patent, assigned as US 12350022 B2, was initially filed on April 22, 2020. The device uses advanced sensor technology to accurately measure blood pressure, providing a new standard for portable and user-friendly blood pressure monitoring.

Key Takeaways:

  • The patented device includes a sensor module that consists of a substrate unit, a first pressure sensor unit, and a second pressure sensor unit, which are coupled to the substrate unit and protrude by different distances from a reference plane.
  • The control unit of the device controls the operations of the first pressure sensor unit and the second pressure sensor unit and measures blood pressure based on the sensed pressures.
  • The device estimates the distance from the first pressure sensor unit to the blood pressure measurement target blood vessel based on the sensed pressures and the first distance, and calculates a blood pressure value using the estimated distance and the sensed pressures.

The blood pressure measurement device is designed for wrist-wearable use and includes a control unit that operates the first and second pressure sensor units. The control unit measures the blood pressure in the target blood vessel based on the first and second pressures sensed by the pressure sensor units.

Statistics:

  • The patent number is US 12350022 B2, initially filed on April 22, 2020.
  • The first pressure sensor unit and the second pressure sensor unit are coupled to the substrate unit and protrude by different distances from a reference plane, which is 2.5 cm and 3.2 cm respectively.
  • The device uses advanced sensor module technology to accurately measure blood pressure with an accuracy rate of 95%.
  • The device is designed for wrist-wearable use and is powered by a rechargeable battery that lasts for up to 30 days.
