Phlebotomy is the process of making a puncture in a vein, usually in the arm, with a cannula for the purpose of drawing blood. [1] The procedure itself is known as a venipuncture , which is also used for intravenous therapy .
The most common was phlebotomy, or venesection (often called "breathing a vein"), in which blood was drawn from one or more of the larger external veins, such as those in the forearm or neck. In arteriotomy , an artery was punctured, although generally only in the temples.
In medicine, venipuncture or venepuncture is the process of obtaining intravenous access for the purpose of venous blood sampling (also called phlebotomy) or intravenous therapy. In healthcare, this procedure is performed by medical laboratory scientists , medical practitioners , some EMTs , paramedics , phlebotomists , dialysis technicians ...
This name for handheld venipuncture devices first appears in Anglo-Saxon manuscripts around 1000. [1] The name is most likely derived from phlebotome: phlebos, Greek for blood vessel and tome, meaning to cut. [2] These instruments are the progression from the early use of fish teeth, sharpened stones, and thorns used to penetrate blood vessels.
The butterfly's precise placement facilitates venipuncture of thin, "rolling", fragile, or otherwise poorly accessible veins. The butterfly's shallow-angle insertion design facilitates venipuncture of very superficial veins, e.g. hand, wrist, or scalp veins (hence name "scalp vein" set).
The insertion of the needle into the vein crushes the ampule, thus creating a vacuum and forcing blood into the container. Typically, a prominent vein in the forearm such as the median cubital vein would suffice, although the Keidel vacuum can take blood for any prominent peripheral vein.
The majority of its members manage the entire spectrum of venous and lymphatic diseases – from varicose veins to congenital abnormalities to deep vein thrombosis to chronic venous diseases. Founded in 1987, the AVF encourages research, clinical innovation, hands-on education, data collection and patient outreach.
A venipuncture performed using a vacutainer. A venipuncture is useful as it is a minimally invasive way to obtain cells and extracellular fluid from the body for analysis.. Blood flows throughout the body, acting as a medium that provides oxygen and nutrients to tissues and carries waste products back to the excretory systems for disp
