Mindray BeneVision N15 Service Manual

BeneVision N17/BeneVision N15/BeneVision N12 Patient Monitor Service Manual 3-5
3.1.5.2 NIBP Accuracy Test
Tools required:
 T-shape connector
 Tubing
 Squeeze bulb
 Rigid vessel with 500 ± 25 ml internal volume
 Reference manometer (calibrated with accuracy equal to or greater than 1 mmHg)
Follow this procedure to perform the test:
1. Connect the equipment as shown below.
2. Before inflation, the reading on the manometer should be zero. If not, open the valve of the squeeze
bulb to let the whole airway open to the atmosphere. Close the valve after the reading turns to zero.
3. Select Main Menu → Maintenance → enter the required password → Module → NIBP → NIBP
Accuracy Test.
4. Check the reading of the manometer and the reading of the patient monitor. Both should be 0
mmHg.
5. Raise the pressure in the rigid vessel to 50 mmHg with the squeeze bulb. Then, wait for 10 seconds
until the measured values become stable.
6. Compare the reading of the manometer with the reading of the patient monitor. The difference
should be 3 mmHg or less. If it is greater than 3 mmHg, contact your service personnel.
7. Raise the pressure in the rigid vessel to 200 mmHg with the squeeze bulb. Then, wait for 10 seconds
until the measured values become stable. Repeat step 6.
NOTE
 You can use an NIBP simulator to replace the squeeze bulb and the reference manometer to
perform the test.
 You can use an appropriate cylinder and a cuff instead of the rigid vessel.
