Weiweisi launches AED three-dimensional layout plan to assist Healthy China 2030

2024-05-06

Suzhou, July 11, 2022/American News Agency - Approximately 545000 people in China experience sudden cardiac death each year, equivalent to one person falling down every minute due to cardiac arrest. The golden first aid time for cardiac arrest is only 4 minutes. Cardiopulmonary resuscitation and defibrillation (using AED) are crucial for prolonging the patient's life. How to quickly bring AED to patients within a limited time? Recently, Weiweisi Medical, a medical technology company specializing in cardiac rhythm management, announced the launch of an AED three-dimensional layout solution. Starting from the current situation in China, the company has independently developed fixed position AED, mobile AED, and unmanned aerial vehicle AED. Through the collaborative layout of the three types of AED, it significantly improves emergency efficiency and AED coverage, helping to build a healthy China 2030 emergency system suitable for Chinese characteristics.

Defibrillation is performed on patients within one minute of cardiac arrest, with a survival rate of up to 90%. For every 1 minute delay in defibrillation, the patient's survival rate decreases by 7% -10%. The emergency survival rate in China is only close to 1%, while in some developed countries it can reach 30% -40%. The Healthy China Action (2019-2030) specifically proposes to improve the standards for equipping emergency equipment in public places, and equip automatic external defibrillators (AEDs) in densely populated places such as schools, government agencies, and enterprises.

The distribution of AED in public places should follow the principle that rescuers can receive and return to patients within 3 to 5 minutes, which is a great challenge both domestically and internationally. In China, the use of AEDs faces issues such as low overall coverage, low utilization, and a lack of public emergency knowledge. It is difficult to deliver AEDs to the scene within prime time. How to make first aid faster, more accurate, and more efficient? How to strike a balance between improving the overall coverage, utilization efficiency, and making good use of limited financial resources of AED is a question that requires in-depth consideration.

For example, in city V, with an area of 8000 square kilometers and a population of 10 million, if the city is equipped with a fixed AED, calculated at 200 units per 100000 people, 20000 units are needed; If calculated based on the golden four minute rescue distance, approximately 40000 AEDs are required. However, the situation in densely populated urban areas is different from that in rural areas, mountains, rivers, lakes, and other areas. The layout of using fixed AEDs is obviously unreasonable, which can lead to low efficiency and resource waste.


If using AED three-dimensional layout scheme:


1. Fixed position AED


Fixed position AED can be standby for a long time of four years and is mostly used in public places and relatively enclosed environments, such as shopping malls, teaching buildings, office buildings, etc., radiating to specific areas.


 

2. Mobile AED


The mobile AED independently developed by Weiweisi is only the size of a mobile phone and weighs only about 600 grams. It can transform into a rescue life bag, worn by security personnel, traffic police officers, etc., or equipped on buses, taxis, and patrol vehicles. After receiving the emergency task assigned by the system, the mobile AED will become a mobile emergency station and rush to the scene as soon as possible.


Compared to fixed position AEDs, the direction of action for mobile AEDs has changed from back and forth to one-way, and AEDs are managed by dedicated personnel, saving time in judgment, searching, and retrieval, resulting in higher first aid efficiency. According to calculations, the coverage efficiency of mobile AED rescue is about 6 times that of fixed AED, greatly improving the scope of AED treatment.



3.Drone AED


Weiweisi Medical and AVIC Jincheng Unmanned Systems Co., Ltd., a subsidiary of AVIC Group, have collaborated to develop unmanned aerial vehicle (AED). The total weight of the new model is less than 4kg, and it is recommended to install it in large scenic spots, mountainous villages, and densely populated areas. Unmanned aerial vehicle (AED) has broken through the limitations of ground environment and can overcome conditions such as urban traffic congestion and inconvenient transportation in mountainous/rural areas. In principle, it can be on standby 24/7, reducing emergency response time.



Weiweisi and AVIC Jincheng Unmanned Systems Co., Ltd., a subsidiary of China Aviation Industry Group, collaborate to launch drone AED


Upon receiving an emergency call, 120 emergency personnel were dispatched through the drone comprehensive control system, and the drone automatically exited the cabin to accurately locate the location of the incident. With the help of 5G network, 120 emergency personnel can remotely guide rescue operations and achieve remote transmission of life data without time difference.


Through data interconnection, in the future, drone AEDs will be able to connect city 120 systems, police systems, fire protection systems, and emergency volunteers, integrating more personnel into the application scenarios of AEDs and greatly improving their efficiency.


After calculation, only 1000 mobile AEDs, 100 drone AEDs, and 10000 fixed position AEDs are needed to achieve full coverage of V city. The overall required number of AEDs is 1/4 of using a fixed position AED scheme, significantly improving the unit utilization efficiency of AEDs.


The innovative model of Weiweisi AED three-dimensional layout scheme has opened up a three-dimensional emergency channel from the ground to the air. Rescuers only need to call 120 with one click, and AED will arrive at their side, comprehensively ensuring the health and safety of residents, empowering smart cities, and helping healthy China 2030.
