  • Page 21 O2 pipeline supply inlet assembly Air pipeline supply inlet assembly N2O pipeline supply inlet assembly The anesthesia machine has pipeline and cylinder gas supplies available. Pipeline gas supplies, which are O O and Air, go into the pipeline gas supply inlet assemblies through pipeline connectors 1, 3 and 4 respectively.
  • Page 22 The following picture shows the output connectors of O2 pipeline supply inlet assembly. Fresh gas tube (200 kPa) Drive gas tube Pressure sampling tube for O2 supply gas pressure gauge 2.2.4.2 Anesthetic Gas Delivery System The anesthetic gas delivery system is connected to the gas supplies, anesthetic gas delivery device (vaporizer) and breathing system.
  • Page 23 The following picture takes O2+N2O+Air configuration as an example to illustrate how pipeline gas supplies are outputted. O2 is divided into two pathways (into three pathways if auxiliary O2 supply is configured: system switch 23, O2 flush valve 19 and auxiliary O2 supply 46 respectively).
  • Page 24 When system switch 22 is turned on, Air enters flow regulator 26. O2 is divided into two pathways. One pathway of O2 flows into flow regulator 26 and the other into O2-N2O cut-off valve 25. If the pressure of O2 vented into O2-N2O cut-off valve 25 is greater than 0.1 MPa, N2O can enter flow regulator 26, as shown below.
  • Page 25 Flow regulator 26 controls gas flows. The gases passing through flow regulator 26 enter electronic flowmeter&throttling device 27 and are then converged to enter float flowmeter 28, as shown below. Tube for converged gas tube 27.Throttling device 氧 路 O2 tube Air tube 32.
  • Page 26 The converged gas goes from float flowmeter 28 to the anesthetic gas delivery device (vaporizer), forming fresh gas after mixed with anesthetic agent. The fresh gas then goes from check valve 30 through the ACGO assembly to the breathing system. The flushing O2 also enters the breathing system through the ACGO assembly.
  • Page 27 System Switch Assembly The above picture shows the system switch assembly. Supply gases of Air and O2 go into system switch 22; and Air & O2 flowing into the flowmeter assembly and O2 into the control end of the O2-N2O cut-off valve are outputted. System switch has an electrical outlet which controls the power-on status of the system.
  • Page 28 Flow Control Assembly Flow sampling point and display board 27.Throttling device 26.Flow regulator 28.Float flowmeter The above picture shows the left front panel where the flow control assembly and flow display assembly are located. Flow control assembly 26 (flow regulator) controls the gas flows and the proportion between O2 and N2O as well to ensure that the gas flows outputted are adjustable within the range of 0–15 L/min.
  • Page 29 O2 Flush Button Assembly The above picture shows the O2 flush button assembly. When O2 flush valve 19 is depressed, O2 rushes into the pneumatic circuit which is cut off when this valve is released. The O2 supply gas at 0.2 MPa after regulated goes through the O2 flush valve, the ACGO assembly, and into the breathing system.
  • Page 30 Vaporizer Vaporizer Either double-vaporizer manifold 29 or single -vaporizer manifold 50 is used. Both are integrated with check valve 30 which prevents flushing O2 and fresh gas from flowing back to the vaporizer. When a double-vaporizer manifold is used, Selectatec mounting with interlocking function can prevent the user from turning on two vaporizers simultaneously.
  • Page 31 Two optional input ports (select either of them) 2.2.4.3 Pneumatically-controlled Module of the Anesthetic Ventilator The pneumatically-controlled module of the anesthetic ventilator provides drive gas for the patient to breathe. O2 (or Air) from the gas supply inlet assembly enters the pneumatically-controlled module and is outputted in three pathways: drive gas entering the breathing system, drive gas discharged through the AGSS outlet and drive gas discharged through the PEEP outlet.
  • Page 32 The following is the pneumatic circuit diagram of the pneumatically-controlled module. Proportional electromagnetic valve 10 controls inlet gas flow. Filter 8 filters drive gas again. Regulator 9 regulates presssure inside the pneumatic circuit (approximately 0.2 MPa). “11” is a flow sensor of differential pressure type which monitors gas flow in the drive gas circuit. Mechanical overpressure valve 12 ensures that the pressure in the drive gas circuit does not exceed safe pressure.
  • Page 33 2.2.4.4 Breathing System The breathing system provides a closed loop for the anesthetic gas. The CO2 in the patient’s expired gas can be inspired in the inspiration phase to maintain the temperature and humidity conditions of the patient’s expired gas. During inspiration, the drive gas depresses the bag inside the bellows to force the inside gas to enter the patient’s lung.
  • Page 34 Connected to the anesthesia machine main unit through the circuit adapter, the breathing system is highly integrated. Its tubes are all built in except the tube connected to the patient and the O2 cell cable, as shown below. 43.APL valve 33.

Sodalime canister In case of mechanical ventilation, during inspiration, gas flows through bag/mechanical ventilation switch 41, BYPASS valve 35 or sodalime canister 34, inspiratory valve 33, O2 sensor 39, airway pressure gauge 47, and inspiratory flow sensor 37 to the patient. During expiration, gas flows through expiratory flow sensor 38, expiratory valve 36 and bag/mechanical ventilation switch 41 to the folding bag.

The AGSS transfer system is a blue tube with 30 mm conical connectors at both ends. The inlet of the transfer system is a female 30 mm conical connector and the outlet a male 30 mm conical connector.

  • Page 184 5.4.3.3 Problems Related to Calibration Data of the Sensors After confirming that both the zero points of the sensors and the sampling line connections of the sensors are normal, you can detect if the calibration data of the sensors are accurate by using the valves-test tool.
  • Page 185 If when the D/A value of the inspiratory valve is set to more than “4000”, the flow measured by the standard flow measurement device fails to reach 90 L/min, flow calibration will be failed. In this case, you need to replace the expiratory valve assembly or the monitor board.
