An infusion pump infuses fluids, medication or nutrients into a patient's circulatory system. It is generally used intravenously, although subcutaneous, arterial and epidural infusions are occasionally used. Infusion pumps can administer fluids in ways that would be impractically expensive or unreliable if performed manually by nursing staff.
November 17, 2023 at 12:58 PM. (Reuters) - The U.S. Food and Drug Administration (FDA) on Friday said it had identified the recall of B. Braun Medical Inc's medicine-delivering pump system as most ...
Patient-controlled epidural analgesia (PCEA) is a related term describing the patient-controlled administration of analgesic medicine in the epidural space, by way of intermittent boluses or infusion pumps. This can be used by women in labour, terminally ill cancer patients or to manage post-operative pain. [5]
Peristaltic pump in motion. A peristaltic pump, also commonly known as a roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained in a flexible tube fitted inside a circular pump casing. Most peristaltic pumps work through rotary motion, though linear peristaltic pumps have also been made.
Some systems employ a drip chamber, which prevents air from entering the bloodstream (causing an air embolism), and allows visual estimation of flow rate of the solution. [32]: 316–321, 344–348 An infusion pump suitable for a single IV line. Alternatively, an infusion pump allows precise control over the flow rate and total amount delivered ...
Subcutaneous administration is the insertion of medications beneath the skin either by injection or infusion. A subcutaneous injection is administered as a bolus into the subcutis, the layer of skin directly below the dermis and epidermis, collectively referred to as the cutis. The instruments are usually a hypodermic needle and a syringe.
The pump's air intake is filtered by a rotating screen or the vehicle air filter to exclude dirt particles large enough to damage the system. Air is delivered under light pressure to the injection point(s). A check valve prevents exhaust forcing its way back through the air injection system, which would damage the pump and other components.
The infusion set loaded into an insertion device. An infusion set is used with devices such as an insulin pump. The purpose of an infusion set is to deliver insulin under the skin, fulfilling a similar function like an intravenous line. [1] It is a complete tubing system to connect an insulin pump to the pump user and as such includes a ...
