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

 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


 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

 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

 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

 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

 Always use PPE
 Read manual before using

 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 help

 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

 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

 No power
 Battery not holding charge
 No display
 Bad keypads
 Broken handles
 Flash memory errors
 Plunger sensor errors (syringe)
