External infusion pumps, also referred to as ambulatory infusion pumps or portable infusion pumps, are medical devices used to deliver medications, fluids, or nutrients to a patient's body in a controlled and regulated manner. These pumps are typically external to the patient's body and provide continuous or intermittent infusion through a catheter or needle inserted into a vein or other appropriate site.
The primary function of external infusion pumps is to administer medications or fluids that cannot be taken orally or require a more precise dosage delivery. These pumps are commonly utilized in various medical settings, including hospitals, outpatient clinics, and home healthcare. They can be programmed to deliver specific doses at specified intervals, ensuring accurate and consistent administration over an extended period.
External infusion pumps typically consist of a pump mechanism, a reservoir or cartridge housing the medication or fluid, and a control interface for programming and monitoring. Advanced models may also include safety features, alarms, and data recording capabilities to enhance patient safety and facilitate therapeutic management.
These pumps can be used for a wide range of medical purposes, such as pain management, chemotherapy, parenteral nutrition, insulin delivery, and antibiotic therapy. They offer the advantage of allowing patients to move about more freely while receiving treatment, enabling ambulatory care and reducing the need for extended hospital stays.
Overall, external infusion pumps play a crucial role in delivering accurate and controlled infusions of medications and fluids, improving patient care and convenience in various healthcare settings.
