Device longevity

Device longevity is a function of flow rate. Flow rates affect the battery voltage and motor
revolutions (Figure 3).

Figure 3. Typical device longevity based on flow rate.
Device longevity is the calculated number of service months remaining based on actual usage

rates. An elective replacement indicator (ERI) message displays on the programmer when
the pump nears the end of its service life (EOS). At ERI, the pump continues to operate within
specifications. The ERI thresholds allow the pump to operate for a minimum of 90 days, at
rates up to 1.5 mL/day, between ERI activation and EOS (Figure 4). When activated, ERI is
date stamped and displayed by the programmer after interrogating the pump. The EOS
activation indicates the pump has reached the end of its service life. At EOS, the pump stops,
but telemetry is available until the pump battery is depleted.
1 Device longevity sources include battery life (voltage), device life (years), and motor life (revolutions).
