An infusion pump is a medical device used to deliver fluids, such as medications or nutrients, directly into a patient's bloodstream. These pumps can provide precise control over the flow rate and dosage, ensuring that patients receive the correct amount of treatment over a specific period. They are commonly used in hospitals, clinics, and home care settings. Infusion pumps come in various types, including volumetric pumps, syringe pumps, and patient-controlled analgesia (PCA) pumps. Each type serves different purposes, such as administering chemotherapy, pain relief, or hydration. Their accuracy and reliability make them essential tools in modern medical care.
