This is a result from the cooperation the application of reliability technical and icro-processor controlled between Shanghai Medical Equipmetn Factory and the Teching and Research Section on reliability of Shanghai No.2 Industrial University.Ventilator comes as a electronic-controlled electric-drivedn,time cycled,volume constant ventilator for the ventilation administration and care for the patient of respiratory failure in emergency site.During transportation of patient,in hospital or at home,with a well designed cylinder pump system the ventilator is able to without an air compressor,output a precise volume and save the time for maintenance. Oxygen concentration in the inhaled gas can be adjusted through a oxygen enrichment kit connected to the gas take-in socket,the ventilator can also be furnished with humidifier,oxygen analyzer,etc.to extend clinical application.With internal battery keeps machine work another 120 minutes.
