What is the primary function of an infusion pump?

The primary function of an infusion pump is to deliver fluids, nutrients, or medications into a patient's circulatory system in a controlled manner. This device is crucial in medical settings, as it provides precise administration of intravenous therapies, ensuring that patients receive the correct dosage over a specified period. By controlling the rate and volume of infusion, healthcare providers can tailor treatments to individual patient needs, which is particularly important in cases requiring careful monitoring of fluid and medication levels, such as in chemotherapy, pain management, or hydration therapies.

In contrast, draining excess fluids from the body is typically associated with devices like drainage systems or suction pumps, which serve a different purpose. Monitoring vital signs is a function of vital signs monitors, which are used to continuously track patient health indicators like heart rate and blood pressure. Additionally, performing surgeries autonomously implies a role that is far beyond the capabilities of an infusion pump, as surgical procedures require comprehensive planning, precision, and human oversight, typically involving surgeons and surgical equipment.
