Is an infusion pump a pressure pump?

No. An infusion pump is a medical device that is used to infuse medications, nutrients, and other fluids inside the body. The working principle of the infusion pump is to drive the piston or roller and other components through the motor, the liquid from the infusion bag or vial, and through the infusion pipeline to the patient's body. The main function of an infusion pump is to control the speed and volume of infusion to ensure accurate delivery of medication or nutritional fluids. Unlike pressure pumps, infusion pumps do not work by pushing the fluid through pressure, but through mechanical movement to achieve infusion.
