Medical Device · Blood Glucose Meter · Lithium Battery

Introduction

Blood glucose meters are precision medical devices where measurement accuracy, stability, and reliability are critical. From an engineering perspective, the battery is not a secondary component but a core subsystem that directly influences signal stability and overall system reliability.

Electrical Stability Requirements

Blood glucose meters operate at very low power levels but require extremely stable voltage during each measurement cycle. Any voltage fluctuation can affect sensor accuracy. Lithium batteries provide stable discharge characteristics and low internal resistance, ensuring consistent and repeatable measurement performance.

Battery Configuration and Cell Selection

Most blood glucose meters use a single-cell lithium battery architecture. Engineers must carefully evaluate capacity, self-discharge rate, and mechanical consistency to achieve compact device design while maintaining long operating life and predictable performance.

Protection and Safety Design

Integrated protection circuits are essential to prevent overcharge, over-discharge, and short circuits. These safety mechanisms ensure reliable operation and compliance with medical device safety requirements.

Charging and Lifecycle Performance

Lithium batteries offer predictable charging behavior and long cycle life, making them suitable for daily-use medical devices such as blood glucose meters. Stable lifecycle performance reduces maintenance frequency and improves user experience.
