Volumetric Infusion Pump :-
Volumetric infusion pumps are used to deliver intravenous fluid products to a patient safely and accurately. Various types of intravenous products, such as medicines, blood products and parenteral nutrition, can be delivered through the volumetric pump.
Plastic tubing is attached to an intravenous fluid bag that is threaded through the volumetric infusion pump; this tube is connected by intravenous access to the patient.Such types of volumetric pumps are configured by the nurse according to the instructions of the doctor to administer medication to a patient at a precise or titrated level.
The volumetric infusion pumps have monitoring sensors designed to protect the patient, such as a sensor that alerts if the plastic tubing produces air bubbles. Nurses monitor the patient's safe delivery of intravenous fluids or drugs.
The Volumetric pumps may inject controlled amounts of fluid or medicine into the flow by producing high and controlled pressure.
Volumetric Pumps operating mechanism :-
Most volumetric pumps operate through two general mechanisms: a mechanism of reciprocation or rotation. Engineers use positive displacement pumps, particularly in the chemical industry, for systems requiring pressurized fluids. Nonetheless, in small plants and factories you will find these kinds of pumps. Another classic positive displacement pump is the injection systems for engines.
Difference between Volumetric Pumps and Syringe pumps :-
Volumetric Pumps :-These devices are used for large amounts of medication being delivered.
Syringe pumps :- Syringe pumps deliver small doses of high concentration medications over the course of a longer period of time.
