12.11 Trumpet Curves
In this pump, as with all infusion systems, the action of the pumping mechanism
and variations in individual sets cause short-term fluctuations in rate accuracy. The
following curves show typical performance of the system in two ways:
1) the accuracy of fluid delivery over various time periods is measured (trumpet
curves), and
2) the delay in onset of fluid flow when infusion commences (start-up curves).
The test protocol used to obtain these results is described in the EN 60601-2-24.
For further information, please refer to this IFU.
This graph is therefore representative of pump and sets used during trials and
serve as an indication only of the pump’s overall performance. Please contact our
After-Sales Department for the other curves.
