Maintenance of ultrasonic diagnostic equipment
    In the process of using the instrument, the ultrasound diagnostician should maintain the instrument in addition to operating according to the regulations. In order to extend the life of the instrument, reduce the incidence of failure, and increase the efficiency, all maintenance should be carried out regularly as needed.
1. Precautions for the use of ultrasonic diagnostic equipment
     1. The operating environment and site requirements of ultrasonic diagnostic equipment

    (1) Temperature: 10℃~40℃;

    (2) Pressure: 70~106KPa;

    (3) Humidity: 15%-95%;

    (4) Inspection room: There is no direct sun exposure and good air convection. There is no interference from power distribution devices, X-ray devices, etc., and stay away from high magnetic field environments;

    (5) Power supply: The socket has grounding conditions.

 

    2. Preparation before starting

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

    (2) Check the connection status of connecting cables, wires, etc. and the setting position of the instrument control keys to confirm whether the instrument is in a state where it can operate correctly.

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

Precautions during use

    (4) After starting up, pay attention to whether the mechanical sound of the instrument is normal, and observe whether the self-checking procedure is correct;

    (5) Always monitor whether the host, monitor and patient are in a normal state;

    (6) Once there is a sudden power failure, immediately restore the power of the instrument to the "OFF" position; after the voltage stabilizes, restart it;

    (7) Do not switch the instrument at any time;

    (8) If the instrument suddenly stops automatically, the power should be cut off, and professional maintenance personnel should help;

    (9) The patient is not allowed to touch the instrument.

 

    3. Precautions after shutdown

    (1) Turn off various operations and set the control keys to the state at the beginning of use;

    (2) Turn off the power switch of the instrument first, then turn off the power switch of the voltage stabilizer to cut off the power;

    (3) After the instrument is sufficiently cooled, cover it with the instrument cover.
2. Ultrasonic system maintenance and repair
     1. When performing maintenance or cleaning, put the system into STANDBY state, turn the power switch to OFF, and unplug the main switch. Note: Avoid using any strong solvents, such as thinner or benzene, to avoid damage to the instrument housing.

 

     2. Clean

     (1) Use mild detergent and moist cloth to clean all external surfaces of the instrument regularly.

     (2) When cleaning the keyboard and display screen of the instrument, be careful not to let liquid flow into the instrument and warn against scratching the display screen.

 

     3. Air filtration

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

     (2) The filter device is located at the bottom or other parts of the front of the instrument. According to the air filtration conditions, choose a vacuum cleaner or soapy water to clean the filter plate.

     (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.
3, the maintenance and maintenance of the probe
     1. The probe is easily damaged by mechanical impact, especially the surface in contact with the body surface, so it must not be dropped on the ground or collided.

     2. Never immerse the entire probe in water or other liquids. The cable connection part of the probe is not waterproof.

     3. Excessive bending or twisting of the probe cable may cause incorrect operation of the instrument and probe or internal short circuit.

     4. After the probe is used, wipe the ultrasonic coupling agent clean. When cleaning the probe, it can be cleaned with a mild detergent and a damp cloth. The probe should always be kept clean.

     5. Do not use gas, liquid or high temperature methods to sterilize the probe, and do not place the probe in an environment of 55°C. These disinfection methods will permanently damage the probe.
