The infusion pump is an instrument that can accurately control the number of infusion droplets or infusion flow rate, ensuring that drugs can enter the patient's body with uniform speed, accurate dosage, and safe operation. At the same time, the infusion pump can also improve the efficiency and flexibility of clinical drug delivery operations, and reduce nursing workload. The infusion pump is usually a mechanical or electronic control device that controls the infusion speed by acting on the infusion catheter.

Commonly used in situations where strict control of infusion volume and dosage is required, such as when using vasopressor drugs, antiarrhythmic drugs, intravenous infusion or intravenous anesthesia for infants and young children. The following is a discussion on the daily operation, maintenance, and preservation of infusion pumps based on clinical applications.
