The pump will alarm when the battery voltage reaches a set minimum level,
which is not able to support 3 minutes running.
•
Battery Degradation Alarm
Sensor Input: Battery Voltage
The pump will determine Battery Degradation Alarm when the battery voltage
reaches a set minimum level after charging to the full capacity.
•
Battery Error Alarm
Sensor Input: Battery Voltage
The pump will determine Battery Error Alarm when the battery voltage reaches
a set minimum level or no battery voltage signal received, which means the
battery loses function or is not connected.
•
Total Power Failure Alarm
Sensor Input: Battery Voltage and Grid Voltage
The pump will determine Total Power Failure Alarm when no battery voltage
and Grid voltage signals received.
•
Communication Fault Alarm
Sensor Input: Microprocessor handshake Voltage
The pump will determine Communication Fault Alarm when no handshake
Voltage received between Control CPU and Monitor CPU.
Fluid Occlusion/Air in Line Detection Overview
The
AMSure
® Enteral Feeding Pump uses infrared sensor, pressure sensors
for fluid detection. One sensor is positioned on the upstream side of the rotor
and the other sensor is positioned on the downstream side of the rotor. The
dual sensor system also provides the capability to distinguish between
upstream occlusions, downstream occlusions. When an occlusion occurs in
the tubing on the fluid supply side of the pump rotor, fluid will be evacuated
from the upstream silicone tubing but not from the downstream tubing. In this
scenario, the pump will continually detect fluid at the downstream sensor but
detect no fluid at the upstream sensor. As a result, an Upstream Tube Alarm
will be generated. When an occlusion occurs in the tubing on the patient side,
the tubing at the sensor will expand improving the pressure signal at the
pressure sensor. In this scenario, the pump will issue a Downstream Occlusion
Alarm.
When there’s air in the tubing moving forward, the air will go through the
downstream tubing where the ultrasonic sensor located. In this scenario, the
pump will initially detect fluid at the sensor, then observe a period where there
is air at the downstream sensor or detect fluid at the sensor again, and then
the air volume is calculated and recorded based on the flow rate and time.
When this occurs, an Air in Line alarm will be generated.
