Detailed Product Description
I. Introduction to Electrocardiograph
1. It adopts digital isolation technology, minimizing the influence of temperature drift and time drift of components, ensuring the instrument's high adaptability to the environment.
2. It uses digital signal processing, with the processor performing drift suppression, AC filtering, myoelectric filtering, and heart rate detection on the ECG signal, guaranteeing the authenticity and reliability of signal processing.
3. It features automatic baseline drift adjustment, effectively suppressing baseline drift caused by interference, optimizing the printing position, and obtaining high-quality ECG tracings.
4. It has the functions of automatic measurement and analysis of conventional ECG parameters, reducing the burden on clinical doctors.
5. It uses a precise hot spot matrix to record ECG waveforms, with clear and accurate tracings, rich text annotations, and complete various markings, suitable for clinical diagnosis and research.
6. It uses 63mm wide high-speed thermal sensitive recording paper to record ECG, with simultaneous collection of twelve leads and real-time recording of three leads. It is efficient, effective, economical and practical for clinical ECG examination, and the rhythm lead can be selected arbitrarily.
II. Requirements for Smart Lithium Batteries in Electrocardiogram Machines
Electrocardiogram machines facilitate the mobile indoor and outdoor operations of medical staff. Providing a continuous, efficient, and stable mobile power source has become the greatest guarantee for the normal operation of such equipment. The solution adopts high-performance battery cells, making the entire battery feature high energy density, light weight, small size, long cycle life, high safety, and high consistency. The solution is as follows:

The intelligent lithium battery protection circuit solution for electrocardiograph machines is as follows:
1. Intelligent Battery Management System (PCM): It adopts the SBS intelligent battery management system, which accurately calculates the battery capacity in real time based on advanced battery capacity calculation principles and reports the battery capacity information to the host in real time through SMBUS. At the same time, it provides protection functions for rechargeable smart battery packs (generally lithium batteries). Due to the chemical characteristics of lithium batteries, it is necessary to provide protection functions such as overcharge, overdischarge, short circuit, overcurrent, and overtemperature to avoid risks such as combustion and explosion.
2. LED Battery Capacity Display Board: The LED battery capacity indicator lights display the battery capacity calculated in real time by the intelligent battery management system in a 20% capacity ratio, providing a visual and intuitive display for customers to use efficiently and conveniently.
3. Overcurrent Protection Chip (PTC): It is mainly designed for secondary protection functions. The PTC self-resetting fuse has overcurrent protection and automatic reset dual functions. The PTC in battery products can prevent high-temperature discharge and unsafe large currents of the battery.
