The covid-19 outbreak made medical ventilators a global commodity, and they were once an invaluable product. Recently, many experts in the live broadcast for us to break down the ventilator industry opportunities.

Ventilator can be divided into household respiratory support equipment, sleep apnea treatment equipment, therapeutic ventilator, first aid and transfer ventilator, high-frequency ventilator, household ventilator, etc. Wang haijiao, managing partner of gotejia investment, said that before the epidemic, the consumption of high-end ventilator was low, and the demand for sleep ventilator was high. After the epidemic, the demand for high-end ventilator was high, and the demand for hospitals was high, while the import of ventilator was the majority.

"Medical resources are limited to support the biggest feeling in wuhan. Many patients need to be rushed into the ward. Ventilator and oxygen are problems." Doctor li wentao, deputy director of the department of critical care medicine at huashan hospital affiliated to fudan university, said that the hospital used oxygen cylinders, breathing machines are divided into two types, a non-invasive breathing machine; The other invasive ventilator requires intubation into the respiratory tract. Critical patients need to switch from noninvasive ventilator to invasive ventilator. At present, invasive ventilators are still mainly imported, and all of them were imported before. In the past two years, domestic brands of ventilators have gradually entered hospitals and their quality has been constantly improved.

Wang explained that the research and development of invasive ventilator is more difficult than that of non-invasive ventilator, which takes about two years and at least three to five years. In terms of production requirements and production environment requirements, innovation is higher than non-invasive, and consumables are more invasive than non-invasive. At present, the production level of ventilator in China is still far from that of top countries, but the number of countries that can produce ventilator in the world is still small.

It is reported that the parts of the ventilator are very complicated, more than 1,000 parts are needed to produce an invasive ventilator, most of the key components of the suppliers are foreign manufacturers. For example, the chip of ventilator belongs to the type with high technical content, and it must have strong big data processing ability to ensure the reliability and safety of the ventilator. Moore elite Zhang Jing chairman Yang said that in addition to the chip, medical breathing machine and some parts are supply by foreign manufacturers, such as solenoid valve, solenoid valve is breathing machine oxygen source switch valve, at present there are two main suppliers, one is the MAC, another is the Italian camozzi.

The company's proportional valves come from Germany and Italy, the turbines from Germany and the pressure sensors from the United States, according to an official at a medical equipment company that makes ventilators in nanjing. "We are also trying to use alternative materials, but the ventilator has strict requirements on the long-term reliability and safety of the equipment. Only by solving the material rationing of the source supplier can we improve the production quality and quantity."
