The parts of the ventilator that need to be cleaned and disinfected according to the requirements of the ventilator instructions. Some parts only need to be cleaned, and some are allowed to be disinfected. These parts mainly include the following:
(1) The outer surface of the main engine and the compression pump:
The outer surface of the main engine and the compression pump can be gently wiped with a clean soft damp cloth, once a day or once every other day. If necessary, scrub with a soft cloth soaked in a disinfectant solution such as a chlorine-containing agent disinfectant solution.
(2) Air source filter:
Air source filters include air compression pumps and cleanable air filters in some ventilator mainframes. This part is at the air inlet end of the air path. If it is not cleaned in time, the filter screen will be blocked by dust, which will cause the ventilator to enter and exit air poorly, increase the load and affect the life of the compression pump. The specific cleaning method is: take the filter out of the machine, wash the surface dust with clean water, and then vigorously shake it or dry it; or use a vacuum cleaner to suck up the dust and put it back in place. Generally, it is cleaned once every 48 to 72 hours without routine disinfection.
(3) Electronic devices inside the ventilator:
The dust on the surface of the electronic components inside the ventilator can be gently sucked off with a low-power vacuum cleaner or gently blown off with a special suction ball, or it can be gently swept away with a clean soft brush. The electronic components cannot be soaked in disinfectant or touched. Water and oil.
(4) Sensor:
Various sensors such as flow and pressure are sensitive electronic parts of the ventilator. They cannot be washed with water or immersed in disinfectant to avoid damage to its performance. If necessary, use gas disinfection to disinfect the surface. Only 70% alcohol cotton balls can be used on the surface. Be very careful and gently wipe clean. Some sensors can only be gently immersed in clean water, immediately removed, and allowed to dry naturally. Do not shake or tumble dry.
(5) Humidifier:
The electronic heating part of the humidifier and the metal part of the temperature control sensor probe should be gently wiped with a clean soft damp cloth. It should not be soaked in disinfectant, so as not to affect the heating function and reduce the accuracy of its temperature sensing.
(6) Gas pipeline:
The gas pipeline is a part of the ventilator that needs to be sterilized. All threaded tubes, connecting tubes, joints, humidifiers, nebulizers, and exhalation flaps that are connected between the patient and the ventilator should be thoroughly disinfected, and can be used first Rinse the dirt in the pipeline with clean water, then immerse the pipeline in the prescribed disinfectant for about 1 hour, take it out and rinse the disinfectant inside and outside the pipeline with clean water, dry it in a cool place and use it again.
(7) Air filter:
The air filter is installed on the front panel of the ventilator or in the breathing gas pipeline of the patient for easy disassembly and replacement. The air filter is generally a single-use part. The function of the air filter is to filter out the air in the ventilator. Bacteria, to ensure the cleanliness of the gas entering and leaving the patient, the air filter should be replaced regularly according to the relevant requirements of the ventilator user manual.
(8) Body and countertop: The body and countertop are mainly used to remove dirt and dust on the surface in time with a soft cloth. When it needs to be pushed to the laminar flow aseptic ward, it is also necessary to clean the surface with a disinfectant, and the dirt on the roller part of the rack should be carefully removed.
