Cardiac arrest is a prevalent clinical emergency characterized by its high incidence, sudden onset, challenges in resuscitation, and low success rates. Timely and effective cardiopulmonary resuscitation (CPR) is the key to improving the success rate of patient rescue. Currently, manual CPR serves as the primary clinical approach. Due to the high intensity of physical exertion, the depth and frequency of external chest compression decrease with the extension of CPR time, resulting in a lower success rate of CPR. Although existing mechanical resuscitation devices address issues such as compression frequency, amplitude, and reduce the physical burden on medical staff, they are associated with complications for patients (e.g., sternum and rib fractures). Additionally, these devices are often expensive, bulky, and reliant on external power sources, limiting their clinical utility. To address these issues, the medical staff of the department of critical care medicine of the Second Affiliated Hospital of Zunyi Medical University designed a cardiac resuscitation device specifically for critical care and obtained a National Utility Model Patent of China (patent number: ZL 2019 2 2003762.8). The device is 25 cm long, 20 cm wide, 25 cm high, and weighs approximately 2.5 kg. On one side of the main body, there are longitudinally arranged adjustment knobs, a power switch, a power jack, and a heat dissipation window. The left side of the device features a touchscreen display, which shows parameters including screen contrast, alarm volume, defibrillation energy, time, battery level, heart rate, and electrocardiogram waveforms. Below the touchscreen, a physical control interface-comprising up/down keys, left/right keys, and function buttons-allows adjustment of all parameters displayed on the screen. To the right of the control interface, there is a shock current device that can be directly removed and placed closely to the patient for defibrillation treatment. There is a 48 V lithium battery inside the device, and a solar panel on the other side wall of the main body, which can automatically charge via sunlight. There is a strap on the other side wall of the main body, which contains a flexible sponge layer for comfortable wearing. The upper wall of the main body is equipped with a handle for easy carrying. The heartbeat restorer for critical care medicine has a simple structure, small size, light weight, low cost, easy operation, and strong mobility. It can meet the needs of cardiac arrest patients in different places, especially those in disaster areas who cannot be sent to the hospital for rescue in a timely manner. It is worthy of clinical promotion and application.
