Equipment & Instrumentation: Automatic Pressure Injectors
Parts |
'Head' where syringes with contrast material are inserted
Plungers push the contrast into tubing attached to catheters High pressure mechanism - Electromechanical system with motor drive connected to a screw. Floor or overhead mount Control unit where flow rate and volumes are programmed |

|
Equipment & Instrumentation: Automatic Pressure Injectors
Function |
Administers a precise volume (bolus) of contrast at a rapid preset flow rate
Bolus injections rates for LV-gram, PA, Aorta are 30-60ml at 15-30ml/sec Watch for bubbles!! |

Equipment & Instrumentation: Automatic Pressure Injectors
Operation |
Load Syringe
Set Flow Rates Press trigger to inject/or during cine from table Safety features: warns of omitted settings or mechanical malfunction Volume limiting device Pressure limiting device: sets max PSI, prevents catheter to whiplash (recoil), breakage, vessel damage Accelerator regulators: guards against recoil, exact duration of time Rate rise control: allows for gradual rise in PSI |

Equipment & Instrumentation: Automatic Pressure Injectors
Types & Control Panel Info |
Air compressed (not used)
Pressure Dependent Fixed Flow Rate ** Flow rate - amount per time Volume - total amount Linear Rise - time to reach desired flow PSI - pressure that you inject Injection delay - inject late Film changer delay - to inject early |
