The central monitor has many functions. It can not only monitor the ECG and respiration of patients, but also monitor various physiological parameters of human body such as blood pressure and oxygen saturation. In addition, it can be connected with the central station through network lines, so many hospitals will use the central monitor. However, some hospitals find that there will be a "pump leak" when doing non-invasive blood pressure test. What should we do at this time?

1. Check the air pump

After seeing the prompt of pump air leakage, first, carefully check the external airbag and inlet pipeline to see if there is any air leakage. If there is no air leakage and it can be inflated normally, this part is no problem. Next, we must continue to search for air pumps related to inflation. You can open the chassis on the back, stick your ears on the air pump and listen carefully to see if there is any air leakage. If there is only a small operation without obvious air leakage, you can initially suspect that the internal structure of the pump is damaged, and you can replace the air pump. If it remains the same after starting up, it is not the air pump damage.

2. Test the auxiliary gas path

Besides the air pump, it is necessary to detect and inflate and deflate the attached air circuit. When checking, it is necessary to isolate static electricity first, or discharge static electricity first. Only when the power is off can the back cabinet be opened, and then carefully remove the square circuit board in the middle. There are two solenoid valves used for deflation after inflation. Check these two solenoid valves separately. If there is no problem, replace the hose connected with it, seal both ends with tie straps, and then restart the machine to check whether the pump leaks.

For medical institutions, the central monitor is a very important kind of medical equipment, so any abnormal phenomena of the monitor should be eliminated in time. If there is a prompt of "pump leakage" during the use of the monitor, the technicians should take correct measures in time to check and eliminate the cause of the fault.
