Infusion Pump :- An infusion pump infuses fluids, drugs or nutrients into the circulatory system of a patient. Although subcutaneous, arterial and epidural infusions are occasionally used, it is generally used intravenously.There is extensive use of infusion pumps in clinical settings such as hospitals, nursing homes and home.
Infusion pumps offer significant advantages over manual fluid management, including the ability to deliver relatively small volumes of liquids, and the ability to deliver fluids at precisely controlled levels or automatic intervals. Nutrients or medicines such as insulin or other hormones, antibiotics, chemotherapy drugs, and pain relievers can be supplied.
Infusion pumps may deliver liquids in ways that, if done manually by nursing staff, would be impractically ineffective. For example, injections of as little as 0.1 mL an hour (too low for a drip), injections each minute, injections with regular boluses required by the patient, up to the maximum number every hour, or fluids whose volumes differ by day. Because infusion pump can often generate very large yet regulated pressures, they may administer controlled quantities of fluids subcutaneously (under the skin) or epidurally (just within the central nervous system surface – a very popular local birth anesthesia).
