The working anesthesia machine and anesthesia ventilator need daily disinfection, in other words, a new or disinfected pipeline should be used every day (including the pipeline used for the first time). Patient's exhaled pipelines should be cleaned and disinfected. Two anesthesia machines can be used and disinfected alternately.
When the patient stops using the anesthesia machine, the anesthesia machine should be terminally disinfected, that is, anesthesia machines should be installed for use again after a thorough cleaning and disinfection.Anesthesia machine which hasn’t been used for a long time should be cleaned and disinfected when it is used again.
Record of cleaning and disinfection work should be archived for future reference.
The machine after cleaning and disinfection must be checked thoroughly for use the next time according to the checklist.
The focus parts which need cleaning and disinfecting include the surface of machine, fan filters, flow sampling tube, the breathing tube ,gas storage bag, breathing valve and housing, sodium lime tank and anesthesia breathing circuit principal part, and folding bag.
8.3.1 Cleaning of machine surface: Use the moist and soft rag, which contains a common water-soluble disinfectant, to clean the panel and surface of the anesthesia machine. You must prevent the disinfectant from entering into the anesthesia machine and the insider of the anesthesia ventilator. Don’t use organic solvent to clean the product surface.
8.3.2 Cleaning of the fan filter of the anesthesia ventilator: get rid of the sponge, use soap water to clean and then dry it, and reinstall the back cover of the ventilator. The working anesthesia ventilator should generally be checked and cleaned once every 24 hours.
8.3.3 Cleaning of the flow sampling tube: wash the flow sampling tubes with fresh water to clean the sputum, blood, oil and other residue on the surface. Wash the dirt on inner-wall with neutral detergent.
8.3.4 Cleaning and disinfection of the breathing tube: it should be flushed with soap water every time a new patient uses it. Put 0.05% Iodophor solution or Sterilized royal liquid into it to disinfect for 30 min, then flush it with clean water and dry it for later use; or put it into a disinfecting steamer for disinfection or soak it in 70% alcohol for 30 min.
8.3.5 Cleaning and disinfection of gas storage bag: the gas storage bag used by each patient should be flushed with clean water. Put it into the disinfecting steamer for steaming disinfection after drying the water in the bag. Please don’t disinfect with ultraviolet rays, otherwise, it will quicken the aging of rubber products.
8.3.6 Cleaning and disinfection of breathing valve and housing: clean the breathing valve and housing with the aseptic gauze soaked with the water-soluble disinfectant, and recover after drying it.
8.3.7 Cleaning and disinfection of the sodium lime tank and anesthesia breathing circuit principal part: use the manners as steaming and disinfectant soaking, etc to disinfect after flushing it with soap water. If it’s soaked with the disinfectant, the high pressure air or oxygen should be used to dry the disinfected components after finishing the disinfection.
8.3.8 Cleaning and disinfection of the folding bag: washing gently in order to prevent the folding bag from damaging, and add enzyme-free soft detergent for rubber and plastic to the hot water.
Equipment with functional failure should not be used. Guarantee should be made that any maintenance of the anesthesia machine should be completed by our company or authorized agents. The performance of ventilators must be verified to comply with the description of this manual after repair.
A thorough cleaning, disinfection and maintenance of the anesthesia machine should be carried out every six months. Specially-assigned person should be responsible for that. Maintenance records should archived. Before restarting the ventilator which hasn’t been used for six months, a comprehensive performance test should be carried out.
The "Malfunction Analysis and Failure Elimination” provided by this guide are the basic methods to deal with the anesthesia ventilator failure. If failure still cannot be ruled out, or failure repeatedly occurs by those methods, please promptly notify our company and authorized service agencies.
The storage emergency battery should be charged in time after use, the time interval cannot be longer than 24 hours.
If the emergency battery does not discharge for 6 months, it must conduct a maintenance treatment of charge-discharge operation. That is to operate the anesthesia ventilator powered by the emergency battery until the emergency battery cannot continue to drive the anesthesia ventilator, and then recharge the emergency battery power until it is fully charged.
When changing the emergency battery, you should pay special Warning to the polarity——red line is connected to the anode, and black line to cathode——you definitely cannot connect it in a wrong way. The polarity wiring should be connected tightly to avoid open circuit, heating or striking a light.
Don’t put the emergency battery near heat sources (such as the radiator). Don’t expose it to strong direct sunlight. Don’t cover anything on the battery to prevent damage to the battery due to the high temperature. Keep the battery surface clean. If there is liquid spilled on the battery, it must be immediately wiped clean.
During the process of transportation, storage and use, the storage emergency battery must be placed upright, not upside down or horizontal to avoid furious vibration.

The oxygen concentration sensor belongs to a consumable, so it’s not within the range of warranty.
The oxygen concentration sensor is installed at the inhale end of the anesthesia breathing circuit, and what’s monitored is inhaled oxygen concentration. Although it cannot get in touch with the breath of patient, however, it cannot avoid contacting moisture, therefore, we design the oxygen concentration sensor base, so as to collect moisture. So we suggest to pull off the oxygen concentration sensor base after use every time (could refer to the integrated anesthesia breathing circuit component diagram), unscrew the water drainage port and drain the water, and clean it completely, disinfect and dry it. Pull out the oxygen concentration sensor, dry it so that it could be used normally next time. The oxygen concentration sensor cannot be disinfected, so it could be directly wiped with the neutral solution.
The oxygen concentration monitoring is a function of the anesthesia ventilator, and it’s not a separate monitoring equipment, so the external power supply and internal supply during normal working are relevant powers of the ventilator., if the oxygen concentration monitoring can work normally, please ensure the input power is within the normal range. The power supply of our company belongs to a broad voltage input, so as long as the input voltage fluctuation is within the range as regulated, it will not affect the normal operation of the oxygen concentration monitoring.
When the machine is converted from AC into DC working, the oxygen concentration monitoring and alarm function are not affected, and it could normally work. When there appears low power alarm , Warning should be paid to the short power supply, and at the moment the AC power supply should be resumed as soon as possible.
Because the low pressure hose doesn’t touch the patients, so only cleaning is ok. Please clean it with neutral solution and dry it. clean and sort out it every time after finishing use, put it in the drawer, so as to prevent from accelerating the aging of hose by exposure to ultraviolet irradiation.
Refer to the contents in chapter 7.5 about relevant maintenance.
The parts of the anesthesia machine should be reinstalled on the anesthesia machine in time after disinfection, and examine the basic performance of machine according to in Chapter 5 “Installation and Adjustment” to confirm that each function keeps good.
