Oxygen concentrators are important medical equipment that can separate oxygen from the air for people to use. However, during use, due to various reasons, the oxygen generator may also malfunction. If we encounter this situation, how should we carry out repairs correctly? Next, let me introduce it.
Step 1: Check the cause of the malfunction
When the oxygen concentrator malfunctions, we first need to determine the cause of the malfunction. Only in this way can targeted maintenance be carried out. There are several common causes of faults:
1. Power failure: The power failure of the oxygen concentrator may be caused by unstable voltage, poor power line contact, and other reasons. At this point, we need to check whether the power cord is loose and whether the power plug is in good contact.
2. Abnormal gas flow: If the gas flow rate of the oxygen concentrator is too high or too low, it may cause the machine to malfunction. At this point, we need to check whether the gas flow pipeline is blocked or damaged.
3. Low oxygen concentration: The reason for the low concentration in the oxygen concentrator may be due to clogged filter elements or faulty oxygen sensors. At this point, we need to check if the filter element needs to be replaced and further check if the sensor is working properly.
4. High machine noise: If the oxygen concentrator produces abnormal noise, it is likely caused by internal component wear or failure of the machine. At this point, we need to check if there are any loose components or other abnormal situations inside the machine.
Step 2: Conduct maintenance processing
If the cause of the malfunction is determined, we can carry out targeted maintenance and treatment based on the specific situation. In general, the maintenance and handling of oxygen concentrators can be divided into the following aspects:
1. Cleaning and replacing the filter element: If the inspection reveals that the filter element has expired or is damaged, we need to clean it or replace it with a new filter element. This can ensure that the oxygen concentration and flow rate of the oxygen concentrator are normal.
2. Check the power supply related components: If it is found that there is a malfunction in the power supply, we need to check whether the power cord, plug, and other components are damaged or loose. And it is necessary to check whether the output voltage of the power supply is normal.
3. Check the gas flow pipeline and pressure related components: If a malfunction is found in terms of gas flow or pressure, we need to check whether the gas flow pipeline and pressure related components are blocked or loose. It is necessary to ensure normal gas flow and pressure.
4. Replace faulty components: If it is found that the fault is caused by component wear or failure, we need to replace the faulty components in a timely manner to ensure the normal operation of the machine. In this case, special attention needs to be paid to the safe use of the internal circuit board of the machine.
Step 3: Conduct a test run
After completing the above maintenance procedures, we need to conduct a test run to ensure that the machine is working properly. When testing, we need to pay attention to the following points:
1. Check if the oxygen concentration and gas flow rate have reached the set values.
2. Check if the machine is running normally and if there is any abnormal noise.
3. Check if the internal components of the machine are securely fixed to prevent circuit board failure and safe use.
If the test runs successfully and the machine operates normally, then we can restore the oxygen concentrator to normal use.
Summary:
For medical equipment such as oxygen concentrators, we must carefully inspect and handle them during maintenance to ensure that no new problems are introduced during the maintenance process. It should be noted that in order to ensure one's own safety and the service life of the machine, it is recommended to have professional technical personnel carry out maintenance and handling.
