Infant pulse oximeters are compact medical monitoring devices designed to measure oxygen saturation (SpO₂) and pulse rate in infants and young children.
With the increasing demand for portable healthcare equipment, manufacturers are focusing on smaller designs, longer operating time, and reliable power solutions.
The battery pack is one of the key components affecting device performance. A suitable infant pulse oximeter battery needs to provide stable power output, safety protection, long cycle life, and compatibility with medical device requirements.
For medical device manufacturers, selecting the right custom lithium battery pack supplier is an important step in product development.
What Type of Battery Is Used in Infant Pulse Oximeters?
The most common battery technologies used in infant pulse oximeters include:
- Lithium polymer battery (Li-Po)
- Lithium-ion battery pack
- 18650 battery pack
- LiFePO4 battery pack
Each battery type has different advantages depending on device design, size requirements, and operating conditions.
Lithium Polymer Battery for Infant Pulse Oximeters
Lithium polymer batteries are widely used in portable medical devices because of their flexible design.
利点は以下の通り：
