Reportedly, China has an annual demand of about 5000 on ventilator. Nearly 2400 low-end ventilators are needed, mid-range and high-end 2600. The low-end market of this medical machine is mainly occupied by Chinese manufacturer, but mid and high end part is monopolized by overseas enterprises and products.
As the high-speed technical development of ventilator, giving first-aid to patients with respiratory failure through assisted respiratory equipment becomes an indispensible medical treatment of modern hospitals. In decades, there are more than 20 well-known manufacturers in the peak of technology of ventilator. Some have a long history of more than 20 years, such as Bird from USA. The others’ products have different advantage and accepted by the market, such as PuritanBennett, Newport, Siemens, Teama, etc.
It is estimated that the sales amount of Chinese ventilator market is 2500 and 1/5 are imported from overseas suppliers. During the period of SARS spreading in 2003, the market is growing by 3500. For improving Chinese ventilation ability and changing the situation the high-end ventilator must be imported from abroad, domestic manufacturer should consider the introduce, master and innovate the related technology. The ventilator is a kind of machine with high technology, the technical difficulties of producing ventilator is in precision machining, antifriction alloy and pressure and flow sensor. Regarding them, we can take the design idea of Siemens. They enhanced the reliability of their products by improving flow control valve. Ventilators normally are used for very long term and the reliability is very important to them. And the imported ones are not suitable to cases, because more than 90% of emergency first-aid applies CMV, SIMV, PS, PS+PEEP. So purchasing high-end ventilators without considering the actual application is a big waste, and the mid-range ones are more suitable. It is suggested some key hospital having scientific research task could reduce the amount of high-end ventilator in their purchase list.
