(a) the steps to detect failure

1, first check whether the connection of each component has a problem. (Including various pipelines, storage balloons, soda lime tanks, evaporators, etc.).

2, check the reversing valve, exhaust valve and other flexible and flexible.

3, check the flowmeter performance is not normal.

4, air leakage inspection.


(two) maintenance examples

1, reversing valve

Symptom: The handle of the reversing valve does not move.

Judgment: The commutation spool rusted.

Maintenance: Remove the reversing valve knob and front and rear plates, and then carefully remove the valve core, use sandpaper to polish off the spool and valve sleeve rust, and then apply Vaseline on the valve core and valve sleeve, according to the original location Installed to ensure its flexible rotation.

2, exhaust valve

Symptoms: The exhaust valve handle does not move.

Judgment: exhaust valve spool rusted.

Maintenance: Open the exhaust valve, carefully remove the valve core, use a fine sandpaper to polish off the rust of the valve plug and the valve sleeve, then apply Vaseline on the valve plug and valve sleeve, and install it according to the original position to ensure its flexible rotation. .

3, fast oxygen valve

Phenomenon: There is gas flow at the gas outlet without opening the flowmeter.

Judgment: The fast oxygen supply valve is bad.

Maintenance: Open the quick oxygen valve and change the O-ring or spring.

EEG machine

4、Flowmeter

Phenomenon: O2, N2O ratio is lower than 1.5:3.5

Judgment: The gear adjustment device is loose.

Maintenance: Loosen the N2O gear jacks so that the gear shaft can rotate freely. Turn the O2 and N2O knobs so that the O2 and N2O ratios are 1.5:3.5. Fix the O2 knob and turn the O2 gear by hand to make the O2 gear and the retaining wheel jam. Tighten the N2O gear top screw.

5, N2O safety valve

Phenomenon: N2O flow meter floats.

Judgment: If there is no problem with the flow meter, there is a problem with the N2O safety valve.

Maintenance: Open the N2O safety valve and replace the diaphragm of the N2O safety valve.

6, breathing circuit

Phenomenon: The breathing circuit leaks.

Judgment: Place the reversing valve knob in the “adult manual” position, block the Y-shaped connector by hand, open the fast oxygen supply valve switch, and the airway pressure should reach 3kPa. If the pressure drops to 0.1 kPa after 1 minute, it is a leak.

Maintenance: Check the interfaces and make sure they are connected. If rubber gaskets, storage bladders, bellows are found to be damaged or deteriorated, replace them before testing.

EEG machine

7, evaporator

(1) Phenomenon: There is a medicinal smell around the anesthesia machine.

Judgment: Evaporator injection drug and discharge drug leakage.

Maintenance: Check the seals and pads of the evaporator injection port and discharge port for damage. If so, replace it.

(2) Density is not allowed

Phenomenon: The evaporator output concentration and scale are very different.

Judgment: Internal evaporator failure.

Maintenance: Return to the manufacturer, repaired by the manufacturer
