At present, more advanced medical devices with the use of electrical isolation and the strength of electrical separation of design, there are three cavities were installed gas line, strong and weak electrical conduit piping, safe and reliable.

Equipment failure with failure including functional and non-functional failures. Devices with problems after the operation, check the cause of the problem, when the fault can not be ruled out, immediately discontinue use equipment belt, disconnect the power, turn off various regulating valves, please test and maintenance of professional and technical personnel.

In the safe use of the process should pay attention: To avoid mis-use in the actual joint, with each outlet end equipment should be clearly marked. Clear; fully inform patients and their families, not be free to use the device with electrical outlets, smoking is prohibited inside the ward; no pressure when the gas fittings or suction outlet when not negative, should consider the possibility of blocked exports, such as failure, shall promptly notify the professional technical personnel to detect and remove.

Control devices: including gas source switching means, decompression regulator means and corresponding valve, pressure gauge and so on.

 
Oxygen pipes: can the oxygen outlet by the control device, oxygen is delivered to the respective terminals.

Oxygen terminal: located in wards, operating theaters and other departments with oxygen, usually mounted on the wall with the device. When oxygen terminal equipped with fast plug-seal socket, use only the oxygen supply (oxygen humidifiers etc.) connector into the jack, then the oxygen supply.

Alarm device: installation in the nurses' station. When the oxygen pressure exceeds the pressure or lower limit, alarm can sound, light alarm signals to alert medical personnel to take corresponding measures.
