Custom Battery Packs for Medical Device – Case Studies

Portable medical devices, ranging from infusion pumps to patient monitoring systems, demand compact, lightweight, and durable power solutions. Off-the-shelf batteries often lack the specific characteristics needed to meet these stringent requirements, making custom lithium battery packs an essential choice for medical device manufacturers seeking to innovate and improve patient care.

When it comes to selecting batteries for medical devices, lithium-ion technology stands out for several reasons:

Energy Density: Lithium-ion batteries provide high energy density, allowing for smaller, lightweight designs without compromising on power output.

Longevity: They offer longer operational life cycles compared to traditional battery chemistries, reducing maintenance and replacement costs over time.

Safety: Advanced safety features, such as thermal management systems and protection against overcharging, ensure reliability and minimize risks in critical healthcare environments.

Medical devices vary widely in their power requirements depending on their application. Key considerations include:

• Voltage and Capacity: Customized to match specific device requirements (e.g., 7.4V, 11.1V, 14.8V, 25.2V…) to ensure optimal performance and longevity.
• Durability: Custom 18650 li-ion battery packs or custom 21700 li-ion battery packs designed to withstand frequent use and potential environmental factors, such as temperature variations and physical impacts.
• Regulatory Compliance: Meeting strict safety and regulatory standards, such as FDA, UL, IEC 60601-1-2, CB (Certified Body) for medical electrical equipment, is essential to ensure patient and operator safety.

At Saphiion, we specialize in developing customized, hassle-free, and cost-effective lithium-ion custom battery packs tailored for diverse applications, including 18650 and 21700 li-ion battery packs for medical device. Our expertise in delivering reliable power solutions underscores the critical role batteries play in enhancing device performance, ensuring safety, and optimizing user experience within healthcare settings.
