A. Anesthesia Ventilator ?Ventilator Ventilation Mode： IPPV, PCV Respiratory Rate： 4bpm～60bpm I/E Ratio： 1:4、1:3.5、1:3、1:2.5、1:2、1:1.5、 1:1、1:0.7、1:0.5、1:0.3 Tidal Volume： 50mL～1600mL Display Tidal Volume and Respiratory Rate for Mechanical/Manual Mode (imported pressure differential flow sensor) Inspiration Pressure： 1.0kPa～6.0kPa PEEP： 0.2kPa～1.5kPa Colored TFT + high luminance LED display Waveform： pressure? time wave flow rate?time wave ?Monitoring parameters： Tidal Volume： 0～2000mL; Minute Volume： 0～20L; Respiratory Rate： Airway Pressure： (Ppeak、Pmean、PEEP); Oxygen Concentration： 21%～100%; Alarm information： Ventilation Mode： Power indication： Silence timing： ?Alarms： Upper and lower limit for tidal volume ; Upper and lower limit for minute volume; Upper and lower limit for airway pressure ; Upper and lower limit for oxygen concentration ; Apnea Power supply failure Silence time for Alarm： 120s Trending curve： 24-hour complete parameter trending curve Oxygen inhaler ?Optional： Built-in Battery ; Supporting Arm B. Anesthesia Machine ?Flowmeter O2/N2O/AIR six-tube flowmeter; Slim tube： 0.1L/min～2L/min ; Thick tube： 2.5L/min～10L/min. ?Oxygen Failure Protection Device： O2 and N2O should be adjusted as per the proportion： be sure that O2 concentration remains above 25%. ?Safety performance： Alarm for oxygen failure; N2O cut-off with oxygen failure; Spill valve; Safety valve; O2 flush： 35L/min-75L/min. ?Gas supplies： 280kPa～600kPa ?Standby cylinder (optional)： 5L cylinder of O2, N2O or air can be selected C. The main Characters ?Monitoring patient?s respiration： It is equipped with the imported flow sensor with the Y tube, reflecting the patients? respiratory state in reality. It can measure the minute volume, flow, Airway pressure and other parameters, and the wave of flow and pressures can be formed. ?Ventilator ： Pneumatic driven and microcontroller controlled, volume constant, pressure constant, for adult and children, Equipped with Germany-originated proportional valve, timely reaction can meet the patient?s requirements. Enjoying the function of automatically flow compensation in compliance ensures the accuracy of tidal volume. Monitoring oxygen concentration ensures the safety of patient. Standby battery keeps it working for another hour even AC fails. ?Vaporizer： Flowmeter (with high precision six-tube flowmeter) O2, N2O and air, six-tube flowmeter enjoys high precision and anti-static Backlighting can simplify the operator?s work. ?Standby cylinder： With standby cylinder, even if the gas supply is not enough or during changing the gas power, it will not affect the operator. D. Safety performance ?Quality guarantee： Establish a first-rank management process of internationalization and standardization. Get ISO9001 certificate, CE certificate from EU, and EU?s 93/42/EEC & EN740 instructions for anesthesia working station. Pass EN60601-1 international electrical equipments safety rules and EN60601-1-2 international electromagnetic compatibility rules.
