Local news in China recently reported that the first pressure swing adsorption (PSA) unit for oxygen generation installed in an ambulance in the country has now been put into service.
The unit is specifically designed for an ambulance from a Shanghai hospital.
The PSA unit is developed and provided by Shandong Kehua Healthcare Technology Co. Ltd (Kehua), a company based in Jinan, the provincial capital of Shandong province.
The PSA was designed with the aim to replace the use of oxygen cylinders in ambulances, because any traffic jam or long distance travel might result in deficiency of oxygen and lead to tragedy, as explained by a spokesman from Kehua.
After years of research and development, Kehua now supplies five product lines of oxygen PSA units, using molecular sieves from France and compressors from the US. LI Keming, Managing Director of Kehua and also the inventor of the ambulance-specific PSA unit has a dream to “let all the families in China in the world to enjoy domestic oxygen therapy services”.
LI was an intern in a hospital in 1981 and it was when he first had the idea to create a machine to generate oxygen and replace oxygen cylinders for convenience and safety purposes. LI also has the aim to list the company in the ‘New Three Board’ by October 2015 and to be listed on the main board before December 2018.
