Pump safety features
Safe telemetry
Your Pump will respond only to telemetry commands from your PPC. Your
Pump will not change when exposed to electromagnetic fields, such as micro-
wave ovens, garage door openers, airport security systems, television or video
remote controls.
Alarms
The most important safety feature of your Pump is its self-checking circuitry.
If your Pump is not working properly, it will signal you with an alarm mes-
sage on the PPC screen and then automatically turn itself off. This feature
ensures that your Pump will always deliver insulin in a controlled, predictable
manner.
Negative pressure reservoir
The Pump reservoir has a negative pressure (vacuum) which will draw in flu-
ids. In the event of a Pump malfunction, this vacuum assures your insulin will
stay in the reservoir. There are multiple safety features to assure that your
body fluids won’t enter the Pump. Only the pumping mechanism can over-
come this negative pressure and deliver insulin to your body.
