3 Diagrams

4 Principles of Operation  Syringe pumps use a series of sensors and a motor driven plunger head to infuse liquid at a precise rate InputsOutputs ACMoving Plunger Full syringeLiquid released at steady rate

5 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

6 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

7 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

8 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

9 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

10 Safety  Always use PPE  Read manual before using

11 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 help

12 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

13 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

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