The structure and fault diagnosis of the monitor

Structure and fault diagnosis of monitor for monitor manufacturer

1. The composition of the monitor:

Two. Summary of the common faults of the monitor:

A. systematic failure  Ltd.

Display (indicator light, display, etc.)

The keyboard

Recorders

Communication control

(5) other (battery, sound, etc.)

Display type fault:

1. Black screen 2. Flower screen 3. Screen wave 4. Interference of water ripple.

Keyboard type failure

(1) the function of a single button is abnormal.

Fault recorder type fault

(1) the function of the recorder, the function of the recorder is abnormal (the paper, the printing is not clear, etc.) 3. The record of the data abnormal print state prompts the "no" prompt "the printing setting is not ready"

 

 Ltd.

 

Communication control class fault

(1) CCTV shows "communication interruption".


Battery failure

AC switch off, DC can't start, DC shutdown, DC can't turn on. 3 hours after charging 24 hours, DC starting time is less than 30 minutes.

Sound fault

There is no sound and abnormal sound

B. functional failure

(1) electrocardiogram (ECG)

Blood oxygen (SPO2)

Noninvasive blood pressure (NIBP)

(4) invasive blood pressure (IBP)

(5) body temperature (TEMP)

6. Respiration (RESP)

Carbon dioxide (CO2)

Anesthetic gas (Muti-Gas)

CO

Fetal prison

ECG

(1) no heart wave shape, data, display "electrode drop", no heart wave shape, data, display "no heart rate detection", no heart wave shape, data, show "no signal reception" (no signal reception), ECG waveform or data instability, large deviation of ECG waveform has interference and clutter when the ECG waveform is regular sometimes no VPC arrhythmia can not be detected

Blood oxygen (SPO2)

(1) no blood oxygen wave, data, display "probe shedding" 2, no blood oxygen wave, data, show "no signal reception" of unstable waveform, data, show that "detection" of oxygen wave disorder or data instability, large deviation of blood oxygen waveform, data long time measurement of blood oxygen waveform, data measurement It is too long to detect blood oxygen waveform and data. When the probe has red light, when measuring blood oxygen, data and waveforms sometimes do not measure blood oxygen accurately.

Noninvasive blood pressure (NIBP)

Blood pressure is not inflated (according to the blood pressure menu key to start blood pressure no response) 2 inflatable pressure (blood pressure is not filled with 184mmHg) (blood pressure is not full) (blood pressure is not accurate) (blood pressure data deviation) (blood pressure data deviation) 4) no blood pressure data is not stored, no storage of blood pressure can start, but there is no pressure numerical display of patient death can also be measured bleeding pressure

Invasive blood pressure (IBP)

(1) IBP can not be adjusted zero (IBP) data is inaccurate (large deviation) 3) IBP waveform is small, IBP waveform has interference, data instability, IBP non waveform, data 6 IBP display "no signal reception"

Body temperature (TEMP)

(2) no numerical display.

Respiratory (RESP)

(1) no respiratory value and waveform (2) the respiratory value is unstable or the deviation is large and the amplitude of the waveform is small.

Carbon dioxide (CO2)

(1) CO2 channel without waveform and data 2 CO2 channel shows "water box blockage" 3. CO2 channel shows "data measurement error" (4) CO2 measurement numerical deviation (not accurate) 5 CO2 not work (no signal reception)

Anesthetic gas (Muti-Gas)

1. The measurement of anesthetic gas is inaccurate.

CO

(1) the measurement of cardiac output is not accurate and there is error

Fetal prison

(1) abnormal sound of fetal heart rate and no fetal heart rate numerical display of fetal heart rate (3) high deviation of uterine contraction pressure (4) numerical waveform instability (4) central platform (1) central platform without data and waveform display (2) central platform dead machine (3) central platform can not normally start (4) central platform shows "communication interruption" 5. Central platform can not control the bedside machine

Three. Common troubleshooting of monitor (with the example of Kim Ke Wei monitor)

A. display type failure:

Black screen

(1) the power indicator light is not bright, the display screen does not display:

Troubleshooting: (1) check the power supply is normal; (2) check the power fuse is normal; (3) check the power switch is normal; (4) check the power module is normal; 5 check whether the internal connection line is off;

The power indicator light is on, the display screen does not display:

Fault check: (1) check whether the power switch is normal; (2) check the power module is normal; (3) check whether the internal connection line is off; check whether the inverter is normal; 5 check whether the drive board is normal (UT3000A, UT4000A, UT4000A Pro and UT6000A) 6 check the display screen is normal; and check the display display Whether the screen backlight tube is normal or not;

(3) the external display does not display:

Troubleshooting: (1) check whether the power supply of the external display is normal; (2) check whether the external interface is normal.
Check whether the internal wiring of the monitor is normal; (4) check whether the central processing unit is normal.

Flower screen

Troubleshooting: (1) check whether there is interference source near the machine; 2 check the input voltage of the inverter (system board power supply) 3. Check whether the display of the display line is good 4) check the performance of the system board and check whether the performance of the board is bad (UT3000A, UT4000A, UT4000A Pro and UT6000A). Examination and display
