Infusion Pumps - Volumetric - Basics
| Abbreviation / other names |
Peristaltic Pump |
||||||||
| What does it do? |
It is used to pump fluids (drugs, liquid food, glucose, saline) into the body. | ||||||||
| How it works |
A bag of fluid is hung on a pole or hook above the pump and
is connected to a tube. The tube is filled with fluid and is
placed in the pump against a series of little fingers or rollers.
As the fingers move or as the rollers turn the fluid is pushed
along toward the patient. The user sets the required flow rate and volume on the pump, then the rollers or fingers move at the speed required for the flow rate set. Once the required volume has been delivered an alarm is activated. The tube passes through an air-in-line detector and will alarm and stop the flow of fluid if it detects an air bubble. Volumetric Infusion Pumps monitor pressure and do not allow the pressure of the liquid infused into the patient to go too high as damage to the vein will result. High pressures will result in an Occlusion Alarm |
