Medical-Grade lithium polymer battery for digital blood pressure monitoring

Date:2025-02-21

According to Grand View Research, the global digital blood pressure monitor market reached $4.27 billion in 2023, with an annual growth rate of 8.1%. China accounts for over 30% of the market share. Key drivers include:

  • Aging Population: Over 130 million elderly hypertension patients in China, yet home monitoring adoption is below 40%.
  • Demand for Precision: The 2022 China Hypertension Guidelines require home blood pressure measurement accuracy within ±3mmHg.
  • Power System Upgrades: 65% of users consider "battery life" the second most important factor after measurement accuracy.

Four Core Challenges of Digital Blood Pressure Monitor Power Systems

Challenge Issue Impact
Voltage Stability Battery voltage drop of 0.3V reduces pump power, increasing measurement error by 2-5mmHg. High (Affects 32% of device calibration)
Battery Life Traditional AA battery solutions require replacement every 6 months, lowering user adherence by 23%. Medium-High (Main complaint of 58% of users)
Low-Temperature Performance Battery capacity drops >40% at -10°C, increasing failure rates in winter. Medium (Significant in colder regions)
Safety Risks 15% of FDA recalls (2019-2022) were due to overheating or leakage. High (Strict safety requirements for medical devices)
