-Precision syringe
-Equipment: electronic scale, oscilloscope
Maintenance Flowchart
Pg. flowchart illustrates the maintenance procedure for the device.
The operational checkout should be corrected using the troubleshooting procedures
given in section 4.4. Once a problem has been isolated to a single assembly, the
assembly should be replaced in accordance with the disassembly procedure provided in
section 4.5.
The device should be calibrated as described in section 4.5. After all maintenance
procedures are completed, perform the Operational Checkout in this section.
Administration set placement
To avoid possibility of fluids contacting the air sensor and pump mechanism, the
solution container should be spiked and set primed before opening a pump door. The
container should also be placed low enough to permit a loop in the tubing to the side of
the device. Position the container so that accidental spillage onto the device will be
minimized. Do not stretch the set when removing it from packing or loading it into the
pump.
