[0002] Pump medicine usually refers to drug therapy performed through an injection pump. A syringe pump is a medical device that can accurately control the drug dosage and infusion rate. It is widely used in hospitals and home care, especially in situations where long-term and timed drug administration is required. The use of a syringe pump can ensure that the drug is delivered to the patient's body at a constant rate, which can reduce the workload of nurses and patients while improving the accuracy and safety of drug therapy. Pump medicine may also refer to the delivery of drugs to specific treatment sites, such as the heart, tumors, etc., through a pumping system. This treatment method is usually used for cancer treatment, heart disease drug treatment, etc., which can increase the local concentration of drugs and reduce systemic side effects.
