This device integrates five medical functions, including ventilator, monitor, defibrillator, ultrasound and infusion pump. Its size is comparable to that of emergency transport ventilators on the market, which greatly improves the efficiency and convenience of emergency personnel in operating medical equipment. Whether in disaster areas, accident emergency treatment sites, or during emergency transport, the device can provide comprehensive real-time monitoring and life support. Especially for rescuers who perform tasks in limited space and complex environments, this device is undoubtedly a weapon that greatly reduces the burden. Its design concept is to pursue the coexistence of extreme compactness and powerful performance. While being portable, it cannot sacrifice product performance. Instead, it must be aligned with the relevant functions of ICU-level equipment. Only in this way can the purpose of moving the equipment in the emergency department forward to the patient's side for support be achieved. It is equipped with an advanced power management system and can be used in AC, DC, and without external power supply. The hot-swappable mobile battery replacement design can easily cope with various scenarios of power outages and field emergency rescue, ensuring the continuous and stable operation of the equipment and providing strong logistical support for the medical team. This device is easy to combine with various aircraft such as helicopters, drones and eVTOL, providing a new solution for aviation medical rescue. Through joint use, emergency equipment can reach the patient more quickly, effectively improving the efficiency of emergency rescue. If transportation is inconvenient or a quick response is required at a disaster site, this joint use mode has irreplaceable advantages.
