Hyperthermia Pump: Parameters Setting and Preventive Maintenance
Page 16 of 20
Measure by using a tachometer:
i.
Close the door. Set the pump speed to 10 ml/min. Use a tachometer to measure the
rotational speed of the pump head. The accepted tolerance is 1.95 rpm ± 25%.
ii.
Press PUMP SPEED again to change the pump speed to 100 ml/min. The accepted
tolerance is 19.65 rpm ± 10%.
iii.
Press once more to change speed to 500 ml/min and repeat the measurement. The accepted
tolerance is 97rpm ± 10%.
e.
Input and Output Temperature Probes
Prepare at least 2 liters of 37
⁰
- 43
⁰
C fluid
i.
Connect the fluid supply to the disposable. Remove the patient line from the luer
connector. Insert the thermocouple approximately 2” into the connector previously
connected to the patient line.
ii.
Press the RIGHT VALVE key to set the valve to the infuse position. Open the fluid supply
and set the pump speed to 500 ml/min.
iii.
Let the temperature stabilize, wait at least 2 minutes. The INPUT TEMPERATURE and
OUTPUT TEMPERATURE value readings (the values not between the parentheses)
should be within (2
⁰
C).
iv.
Compare the numbers displayed to the thermocouple reading. The accepted tolerance is
1
C for fluid temperature between 30
⁰
C to 40
⁰
C and 2
⁰
C outside this range.
v.
Press PUMP SPEED to set the pump speed back to 0 ml/min.
vi.
Press CANCEL to return to the Calibration/Set-Up screen.
