Syringe Pump Flashcards
What is a syringe pump ?
A syringe pump is used to deliver an accurate and precise volume of liquid over a defined time period.
What is a syringe pump used for ?
Medical :
Drug Infusion
Insulin Delivery
Chemotherapy
Laboratory :
Drug testing
Chemical reactions
Cell culture and microfluidics
What are the steps before operation of a syringe pump ?
Syringe Size selection (varies based on application)
Syringe Installation (inserting syringe into clamp)
Tubing Connection ( connection tubing to syringe needle ensuring tubing is compatible with tubing used)
Programming Parameters ( e.g. flow rate (ml/min) , volume, time. direction of flow (pull or push plunger))
What are the steps during operation of a syringe pump ?
Motor Control ( the movement of the syringe can be controlled via a stepper motor which drives plunger movement)
Plunger Movement (either moves inward and expels fluid if on push or draws fluid into it on pull mode)
Feedback and monitoring ( usually position sensors or pressure sensors to ensure constant flow rate, the motor speed is continually adjusted to ensure this. )
Fluid Delivery and Completion ( completion may be marked by an alarm in some models)
What safety features are present in a syringe pump ?
Air bubble detection
Pressure Sensors
Occlusion (blockage detectors)
Limits to flow rate, dosage and volume.
What is tested for when testing a syringe pump ?
Testing of batteries and locks
Start up tests for LEDS and alarms
Operation tests for clamps and LEDs
Pressure cut off test for occlusion feature
Accuracy tests
Air in tubing tests
What trends are expected for future syringe pumps ?
Integration to cloud storage and analysis
AI ( predictive maintenance)
Customisation and wearables as well as disposable pumps
Personalisation (e.g sensor fusion/ closed loop systems)
What are the key components of a syringe pump ?
Drop sensor
Pressure sensor
Safety clamp
Air sensor
Control processor
Function processor.
