| Reason for the Action |
The Infusomat is equipped with a pressure sensor designed to detect upstream occlusions—defined as blockages occurring in the fluid path between the fluid container and the pump.
During active infusion, the system continuously monitors pressure levels and triggers a high-priority alarm if a significant drop is detected. This mechanism ensures early detection of potential problems and supports timely intervention. If the system detects a pressure drop that exceeds a predefined threshold, a high-priority operational alarm is triggered to alert the user.
In very rare cases, if the alarm is triggered multiple times and the user mutes it each time without resolving the actual cause of the blockage (incorrectly muting the alarm without solving the line blockage and confirming “Yes” to the “Upstream occlusion” display prompt upon product reset), the system may begin to treat the current (already low) pressure level as the new reference point for normal operation.
As a result:
· The sensor compares future pressure readings to this low reference value.
· To trigger another alarm, the system requires an additional pressure drop. This means the system may no longer recognise an ongoing occlusion, even though fluid delivery is still impaired. |
