1. Operating environment and site requirements for ultrasonic diagnostic equipment

    (1) Pressure: 70～106KPa;

    (2) Examination room: no direct sunlight, good air convection. There is no interference from power distribution devices and X-ray devices around, and it is far away from high magnetic field environments;

    (3) After confirming that the power switch on the instrument and the voltage stabilizer is in the "OFF" position, insert the plug into the power socket.

    (4) Whether the power supply voltage is stable and whether it is used together with other electrical devices will affect the performance of the ultrasonic diagnostic apparatus.

    (5) After the machine is turned on, pay attention to whether the mechanical sound emitted by the instrument is normal, and observe whether the self-checking procedure is correct;

    (6) Once there is a sudden power failure, the power supply of the instrument should be restored to the "OFF" position immediately; after the voltage is stable, restart the machine;

    (7) If the instrument suddenly stops automatically, the power supply should be cut off, and professional maintenance personnel are required to help;

    (8) First, turn off various operations and set the control keys to the state at the beginning of use;

    (9) After the instrument is fully dissipated, cover it with the instrument cover.

 2. Ultrasound system maintenance and repair

    (1) Regularly clean all exterior surfaces of the instrument with a milder detergent and a damp cloth.

    (2) The air filtration device of the system should be inspected every week, up to 2 weeks, and cleaned if necessary.

    (3) Turn off the power switch when removing the filter device, and do not start the host system when the air filter plate is not installed.

Third, the maintenance and maintenance of the probe

   1. Do not immerse the entire probe in water or other liquids. Below the cable connection of the probe is not waterproof.

   2. After the probe is used, wipe the ultrasonic coupling agent clean. When cleaning the probe, use a mild detergent and a damp cloth. The probe should be kept clean frequently.
