NIBP Leak detection
Used to detect whether the NIBP measurement pump leaks, when switch in NIBP cuffs, it can be used to
start the NIBP inflation process to find out if the closed conditions of NIBP gas does well.
If air leakage test is passed, the system does not make any messages; Otherwise there is a corresponding
error message in NIBP information area.
Leak detection process:
Connect the cuff and NIBP to the openning of the monitor.
Wrap the cuff around a cylinder with proper size.
Enter "NIBP settings" menu.
Turn the knob, move the cursor to "leak testing", press the knob. "Leak detection …" will display beneath
the NIBP parameters area on the screen. The system has began to perform leak detection.
system automatically inflated to the pressure of 180mmHg.
after about 20 seconds, the system will automatically open the valve, which means leakage measurement is
complete.
If there are no message in NIBP parameter area, it means the system leakage phenomenon does not exist. If
"pump leak …" appears, it means that gas leakage may exist. Operators should check whether the entire
connection is loose. After confirming the connection, then conduct a leak detection again. If there is still a
fault prompt, please contact the manufacturer for maintenance.
