The battery lasts for approximately 5 hours (with continuous solution delivery at 25 mL/h) or 4 hours (with continuous solution
delivery at 300 mL/h) in ambient temperature of 25°C with a new fully charged battery.
Test data for flow rate characteristics and occlusion characteristics is shown below.
Tests were conducted based on IEC 60601-2-24:2012 (EN 60601-2-24:2015). For details, refer to IEC 60601-2-24:2012 (EN 60601-
2-24:2015).
Flow Rate Characteristics
Start-up curves and trumpet curves, which are used as typical explanations of flow rate characteristics, are shown. The data below
is representative examples measured for flow rates of 3 mL/h and 25 mL/h with a new TERUFUSION Solution Administration Set
for Infusion pump.
Notes
• Flow rate characteristics are correlated with the infusion set. Depending on the combination of infusion set and pump, the same
data as the representative example may not be obtained.
• Due to the flow rate control by drip detection, the flow rate accuracy will not be affected in the following cases:
• Under -13.3 kPa or 13.3 kPa of back pressure
• Drug solution container placed 50 cm under the pump
1. Start-up
curve
The discharge quantity measured every 30 seconds for a 2-hour measurement period is converted into flow rate values is
shown. These graphs show characteristics from immediately after the start of solution delivery to when flow rate has stabilized.

2. Trumpet
curve
Data for the latter one hour of the 2-hour measurement period is shown, with the horizontal axis showing the observation
window time (minutes) and the vertical axis showing the maximum and minimum flow rate error for each observation window.
The narrower the region enclosed between the top and bottom solid lines (the so-called trumpet curve) is, the less pulsatory
motion there is.
