This Anesthesia Machine is an essential important anesthesia device in an operation room. Its function is to provide oxygen and anesthetic agent to a patient needing to go through an anesthesia operation and perform ventilation management.
This anesthesia machine is intended for use in children and adults with a body weight heavier than 10kg.
This Anesthesia Machine is equipped with an accurate dedicated anaesthetic vaporizer and a safety device for preventing cyanosis and necessary alarm system. During the anesthesia, the patient’s respiratory functions can be managed by using a microcomputer controlled pneumatic electrically controlled synchronizing anesthesia respirator. Each connection part of the whole machine is a standard interface. A highly efficient and large volume soda lime absorber can minimize the re-inhalation of carbon dioxide by the patient.
Operating conditions for Anesthesia Machine:
---------Ambient temperature: 10 ～ 40 ℃ ;
---------Relative humidity: no higher than 80 %;
--------Atmospheric pressure: 860 hPa ～ 1060 hPa.
--------Power requirement: ～220－240V, 50/60Hz, 40VA, to be well grounded.
--------Air source requirement: medical oxygen and laughing gas with a rated pressure ranging from 0.3 to 0.5MPa.
Attention: the AC power supply used for the anesthesia machine must be well grounded.
Attention: the anesthesia machine used must be equipped with a carbon dioxide monitor complying with ISO 9918：1993, an oxygen monitor complying with ISO 7767：1997 and an expiratory gas volume monitor complying with 126.96.36.199 of Medical Electrical Equipment Part II: Special Requirements for Safety and Basic Performance of Anesthesia System.
3.1 Operating mode: circulatory closed, semi-closed and semi-open.
3.2 Gas requirement: medical oxygen and laughing gas with a pressure ranging from 0.3MPa to 0.5 MPa.
3.3 The maximum error of the pressure testing device should not exceed ± (4% of the full scale reading + 8% of the actual reading).
3.4 For oxygen and laughing gas, a special pressure regulator with a safety valve will be provided. The exhaust pressure of the safety valve should not be higher than 6 kPa.
3.5 Indication range of the oxygen and laughing gas flow meter: 0.1 L／min ～ 10 L／min.
When the flow rate ranges from 10% of the full scale value to 100%, the scale accuracy should be within ±10％ of the indicated value.
3.6 The flow meter is equipped with an oxygen-laughing gas proportional control device.
When the oxygen concentration in the mixed gas N2O/O2 conveyed by the anesthesia
machine is no lower than 20% (V/V) or the FiO2 is lower than 20%, the machine will emit an
3.7 When the oxygen pressure of the anesthesia machine is 0.20MPa±0.05MPa, the machine raises a low gas source pressure alarm which is a high priority alarm, and shuts off the laughing gas conveyed to the common gas outlet.
3.8 Oxygen Flush:25~75 L/Min;
3.9 Anesthetic gas concentration adjustment range of vaporizer: ０～5％, relative error ±20 %.
3.10 The exhaust pressure of the safety valve of the respiratory circuit is no higher than 6 kPa.

3.11.11 Ventilation volume lower alarm limit: the adjustment range is 0~12 L/min , and the permissible error is ±20％. The ventilation volume upper alarm limit is fixed to be 25 L/min, the permissible error is ±20％ and the machine should raise a medium level alarm.
3.11.12 Power supply fault alarm: the machine should give audible alarm in case of power outage and the alarm should last more than 120s.
3.11.13 The silencing time of the audible alarm signal should be less than 120s. The alarm status should not be deactivated and visual alarm signal should not be intermittent.
