The heart is the power source of the circulation system of human beings, and the normal systole and diastole is fundamental to blood supply. In case of cardiac arrest, other organs shall run short of blood, and the serious case may lead to death. In recent years, the cases of sudden cardiac death (SCD)are frequently reported, and the root reason is ventricular fibrillation (VF), i.e. the heart stops systole and diastole and begins continuous fibrillation, and the patient shall die within 10-12 minutes if defibrillation is not given timely.
A fully automatic external defibrillator (AED) has been successfully developed by Jousing Medical Co. Ltd. located in BioBAY, a book sized instrument with 2 electrodes, available to effectively rescue the VF paitent within minutes, gaining the "golden time" for defibrillation.
e-Doctor for automatic diagnosis and defibrillation
The electrocardiogram (ECG) is not a strange thing to us, and we should consult the doctor for results after taking ECG examination. The defibrillator developed by Jousing features the automatic identification of cardiac electric signals, i.e. when the electrodes are placed on the correct location of the body, the instrument starts to diagnose whether it is a VF automatically, and the identification can be completed within seconds.
"Instrument test completed, ready for use,"the instrument begins to "speak when Sun Jianyan, general manager of Jousing, opened the box. Each time it is started, the instrument will quickly run the self test and give the timely report. The user shall then affix the electrodes on the appropriate location of the patient according to the illustration, very convenient for operation. Currently the company has completed the development of the defibrillator, and is preparing for the clinical trials and application for the product registration, and the product shall be launched to the market within 2 years.
Replacing import and used for AED deployment
The death toll from SCD in China is 544,000 every year, ranking No.1 in the world, 1.2 times that of US. According to some source, the number of AEDs owned by US households was 1.7 million in 2011, while the figure was less than 1000 in China. Correspondingly, with the perfect AED deployment, the survival rate of the VF patients is 30%, while the rate in China is less than 1%.
Before starting the project, Mr. Sun and his team conducted the survey of the AED market, and he was astonished at the pervasiveness of AEDs in the developed countries. "In the railway, bus stop, airport and other crowded areas, you will see one every 3 minutes, common as the fire extinguishers".
The product has just "stepped out" of the laboratory, but he has had the clear idea of the future targets and modes for promotion. "Now nearly all the AEDs are imported from other countries, so we expect it will replace the import, and reduce the price while keeping the same performance with the foreign products, more suitable for Chinese," said Mr. Sun.
World leading product with domestic technology
SCD is caused from various reasons, e.g. cardiac diseases, strenuous exercise, or no harbinger at all. To save the life of such patients, the rescue shall be done within the golden time of 10-12 minutes after onset, and the use of AED is critical. Jousing has developed the world leading technologies in AED and applied for more than 20 patents for such a small instrument.
"Many people think the imported products are surely better than the domestic products, and we want to get rid of such a prejudice." Mr. Sun and his team are always confident whether in the technologies and the market. He also plans to establish an incubator dedicated for medical devices in the future, to provide the all-round support in fundraising, technology, public services, etc. for medium and small technology companies.
