Troubleshooting And Maintenance; Air-In-Line Assembly - CareFusion Alaris SE User Manual

Table of Contents

The Alaris SE pump Technical Service Manual is available

from CareFusion. It includes routine service schedules,

interconnect diagrams, component parts lists and descriptions,

test procedures, and other technical information, to assist

qualified service personnel in repair and maintenance of the

instrument's repairable components. Maintenance procedures

are intended to be performed only by qualified personnel.

Artifacts: It is normal for an infusion device to produce

nonhazardous currents when infusing electrolytes. These

currents vary proportional to the infusion device flow rate.

When an

The Air-in-Line Detection System provides clinicians the ability

to detect inappropriate amounts of air in the

instrument is configurable to allow single bubble and

accumulated air detection. Accumulated air detection is based

on measurement of the average percentage produced by small

air bubbles passing the detector.

Ensure that the tubing is properly inserted into the air detector

to avoid false alarms. The tubing may be reshaped to ensure

optimum contact with the sensors. Periodically clean the air-in-

line detector to ensure a clear signal can be received (see

Cleaning on page 116).

Air is detected by an emitter (air-in-line arm) which rotates into

position as the latch is closed. A receiver (air-in-line detector),

opposite the arm and just below the pumping mechanism,

sends the air-in-line information to the main processor.
