Principles of Operation Syringe pumps use a series of sensors and a
motor driven plunger head to infuse liquid at a precise rate
Inputs Outputs
AC Moving Plunger
Full syringe Liquid released at steady rate

Principle of Operation
Chassis contains: LCD screen Alarm to alert user of failures and other
issues that need attention Power supply 2 power distribution boards Memory capabilities
Records doses, rates, and settings

Principles of Operation
Chassis contains: Flange clamp sensor
Determines if syringe flange is present
Barrel clamp sensor Determines if barrel of syringe is present Determines size of syringe
Position sensor Determines how far plunger head is from
chassis

Principles of Operation
Chassis contains: Motor and worm gear
Smoothly moves plunger head outwards Unidirectional
Pyramid shaped reflective counter Rotates with motor Counts rotations by reflecting light back at a sensor

Principles of Operation Plunger head contains:
Force sensor Syringe plunger
pushes against sensor Springs attached to
plunger flippers and force sensor detect presence of syringe plunger
Clutch & lever to allow and prevent plunger from moving freely

Applications
Infuse fluids, medication or nutrients into circulatory system
Administers fluids more reliably than humans Improve patient safety by increasing
consistency and accuracy Assist in investigation of incidents by collecting
data in memory

Operation
Place syringe in three clamps (flange, barrel, plunger flippers)
Designate infusion settings on screen Press “start”
Bolus option: quickly moves plunger head to prime syringe
Always pay attention to alarm warnings Use Biomed option for troubleshooting

Preventive Maintenance Replace IV tubing, cassette, and/or syringe Clean machine and chassis of any solution residue Verify software and menu settings are appropriate for
clinical application Examine controls and switches for proper function Confirm lights, indicators, and displays are working Verify flow stops when device is turned off If device includes a feature that requires the IV set to be
closed before it is disconnected (either automatically or manually), verify that this mechanism is operating properly
Check rollers and tubing to see if replacement is necessary Run self-test, if equipped

Preventative Maintenance Examine plug and line cord Verify battery chargers and indicators are working Check suggested replacement date for the battery to see
if the date is passed or approaching Calibrate machine as necessary Check for unusual noise or vibration Examine internal cables and connectors Lubricate as required by syringe pump manufacturer
