What are the advantages of using lithium batteries in electrocardiographs? How to choose a customized electrocardiograph lithium battery charger?

The advantages of adopting lithium batteries in ECG machines are mainly reflected in the following aspects:

1. Excellent Safety Performance: Medical instrument lithium-ion batteries use aluminum-plastic soft packaging in structure, which is safer compared to the metal casing of liquid lithium-ion batteries. In the case of potential safety hazards, liquid batteries can easily explode, whereas medical instrument batteries will only swell up at most.

2. Compact and Lightweight: There is a technological bottleneck in the thickness of liquid lithium-ion batteries, which is not an issue for medical instrument lithium-ion batteries. The thickness of these batteries can be less than 1mm, and they weigh 40% less than steel-cased lithium batteries of the same capacity specifications and 20% less than aluminum-cased ones. This makes ECG machines more portable, facilitating healthcare personnel to conduct ECG checks in various settings.

3. High Capacity: Medical instrument batteries have a 10-15% higher capacity than steel-cased lithium batteries of the same size and specifications, and a 5-10% higher capacity than aluminum-cased ones. This means that ECG machines can operate continuously for longer periods, reducing the frequency of battery replacements.

4. Low Internal Resistance: Through special design, medical instrument lithium-ion batteries have lower internal resistance, which contributes to their high-current discharge performance, ensuring that ECG machines can start quickly and operate stably when needed.

5. Customizable Shapes: Medical instrument lithium-ion batteries can be flexibly adjusted in thickness and shape according to customer needs, meeting the design requirements of different ECG machines.

When selecting and customizing ECG machine lithium battery chargers, attention should be paid to the following points:

1. Voltage Matching: Ensure that the output voltage of the charger matches the charging voltage of the ECG machine's lithium battery. Different models of lithium batteries have different charging voltage requirements, so it is necessary to choose a charger that matches them.

2. Appropriate Current: The output current of the charger should be moderate, ensuring rapid charging of the lithium battery while avoiding overcharging or insufficient charging. Generally, the output current of the charger should be determined based on the capacity and charging time of the lithium battery.

3. Automatic Stop Function: Choose a charger with an automatic stop function. When the lithium battery is fully charged, the charger will automatically stop charging to prevent overcharging from damaging the battery.

4. Brand Reputation: Select chargers from reputable brands, which usually have higher product quality and more comprehensive after-sales services, ensuring the reliability and safety of the charger.

5. Safety: Ensure that the charger has comprehensive safety protection measures, such as overcurrent protection, overvoltage protection, and short-circuit protection, to ensure that it does not pose a hazard to the ECG machine's lithium battery or users during the charging process.

In summary, ECG machines have many advantages when adopting lithium batteries, and when selecting and customizing ECG machine lithium battery chargers, attention should be paid to voltage matching, appropriate current, automatic stop function, brand reputation, and safety.
