WHAT KIND OF TECHNOLOGY IS USED INFUSION PUMP?

Peristaltic pumping mechanism is the technology used in infusion pump. The infusion pumps operates by using a sequence of pump strokes.
For each motor rotation in infusion pump, 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 peristaltic mechanism or curvilinear peristaltic mechanism.
