Safety information that applies to a specific task is included in the procedure description for that task. 1.1 Safety Information 1.1.1 Definitions WARNING Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

  • Page 8: Caution

    service personnel may remove secured (held in place by screws or fasteners) covers. Failure to comply may result in electric shock. Do not place a container filled with liquid on the ventilator. Doing so may result in  electric shock due to liquid ingress inside the AC power connector. Regularly inspect the system power cord and plug.

  • Page 9: Note

    Do not attempt to sterilize or autoclave the ventilator.  To reduce the risk of electrical shock, disconnect AC power from the ventilator  before cleaning. To reduce the risk of fire, do not use a high-pressure oxygen hose that is worn or ...

    2.1.3 Theory of Operation of the Pneumatic Subsystem According to structural composition and function, the pneumatic system of the ventilator can be broken down into 7 parts as shown below, which are gas supply subsystem, blower box subsystem, inspiratory fixture seat subsystem, inspiratory valve subsystem, nebulizing subsystem, patient tube and expiratory assembly.
  • Page 15 The connector of high-pressure O2 inlet is designed to be NIST/DISS as required by the standard to prevent misconnection. The connector of low-pressure O2 inlet is designed to be quick connector which is compatible with (CPC) PMC series and provides pneumatic cut-off function to prevent gas error between the high-pressure O2 and low-pressure O2 inside the ventilator.

Nebulizing nozzle 2.1.3.3 Blower Box Subsystem The schematic diagram of the blower box subsystem is as shown below. The blower box subsystem mixes Air and O2 and delivers the mixed gas to the lower level assembly.

  • Page 17: Inspiratory Valve Subsystem

    The inspiratory fixture seat subsystem is located in the downstream of the blower box. As the inspiratory channel of the system, it is composed of fixture seat, Insp. hold valve, flow sensor and pressure release valve electromagnet. This module has four functions. First, it can actively release pressure to prevent the pressure of the pneumatic system from exceeding the preset pressure.
  • Page 18 The expiratory valve (EV) is an electronically controlled valve. The expiratory valve closing pressure is controlled by proportional valve. When the control current the system gives to the proportional valve is zero, the expiratory valve fully opens. When the system gives the proportional valve certain control current, the proportional valve seals the diaphragm to the valve port by control PEEP pressure.

    2.1.4.2 Patient Tube Patient tube is the peripheral pneumatic circuit of the ventilator, independent of the ventilation main unit. It can be configured as needed. Patient tube connects the ventilator with the patient and humidifies the patient’s inhaled gas. There are disposable and reusable patient tubes. Generally, disposable tubes integrate tube, water trap, and Y piece, and are made of PP, PE or EVA material.
