WHAT KIND OF
TECHNOLOGY IS USED?
Peristaltic
pumping mechanism is used in infusion pump. It operates by using a sequence of
pump strokes.
For
each motor rotation, tubing is squeezed and released, thereby pushing fluid
towards the patient in a series of evenly spaced micro boluses while
prohibiting back flow.
In infusion pump, Speed
and Volume of the fluid flow is decided by factors like roller size and number
of rollers.
Peristaltic
pumping mechanism can be linear or curvilinear,
