Medical Lithium Battery Solutions for Pulse Oximeters Oxi Metre Pulseoximeter

Market Overview and Demand Analysis

A Growing Market for Pulse Oximeters

The global pulse oximeter market reached a valuation of $2.23 billion in 2024, and is projected to grow to $3.13 billion by 2030, according to recent industry reports. This represents a compound annual growth rate (CAGR) of 5.7%, driven by rising health awareness, increased home healthcare adoption, and the growing prevalence of respiratory diseases such as COPD and sleep apnea.

In China, domestic production dominates the pulse oximeter supply chain, with 89% localization in the manufacturing of oximeter devices. Notably, finger-clip and wrist-worn models account for over 60% of registered products, showcasing strong consumer preference for compact and wearable formats.

 Did you know? During the COVID-19 pandemic, pulse oximeters saw a surge in global demand, with over 25 million units shipped in 2021 alone. Post-pandemic, the demand has stabilized but remains strong for chronic condition monitoring.

Key Consumer Pain Points

• Battery Life: Home users—especially those with chronic conditions—require oximeters capable of 24-hour continuous monitoring without recharging.
• Portability: For finger-clip models, devices must remain lightweight (<50g) and slim (≤15mm) to ensure comfort and ease of use during daily activities.

Competitive Battery Specifications: A Comparative Analysis

Optimized Battery Design for Modern Devices

Recommended Cell Selection

For finger-clip pulse oximeters, we recommend the 602531 lithium polymer cell—with dimensions of 6×25.5×32mm and a capacity of 600mAh. This cell meets the thinness requirement and supports reliable power for day-long use.

For wrist-worn devices, a 401020 micro cell (40×10×20mm) is a practical alternative, allowing for sleeker, more wearable designs.

Technology Enhancements

• Low Power Optimization: Incorporating Bluetooth Low Energy (BLE) 5.3 can cut power consumption by up to 40% compared to earlier versions.
• Fast Charging Compatibility: Supporting PD 3.0 fast charge protocol, the lithium polymer cell can charge up to 80% in just 30 minutes, improving user convenience.

Tech Insight: BLE 5.3 offers enhanced periodic advertising and low latency communication, making it ideal for medical-grade wearable devices.

Cost Control Strategy

Bulk Procurement Price: When ordered at scale, the 602531 cell provides notable cost advantages, supporting budget-friendly manufacturing without compromising on quality.

Total Cost Advantage: Compared with NiMH solutions, this setup delivers up to 18% lower total cost, while offering better portability and rechargeability.

Implementation Roadmap

• Validation Testing: Each battery should pass 200 charge-discharge cycles with less than 20% capacity degradation.
• Certifications: Devices must comply with GB 31241-2022 (battery safety standard in China) and ISO 13485 for international medical device manufacturing.
