The procedure itself is known as a venipuncture, which is also used for intravenous therapy. A person who performs a phlebotomy is called a phlebotomist, although most doctors, nurses, and other technicians can also carry out a phlebotomy. [2] In contrast, phlebectomy is the removal of a vein.
The tourniquet distends the veins, making them more palpable and visible. There are many ways in which blood can be drawn from a vein, and the method used depends on the person's age, the equipment available, and the type of tests required. Most blood collection in the US, UK, Canada and Hong Kong is done with an evacuated tube system.
Venous cutdown is an emergency procedure in which the vein is exposed surgically and then a cannula is inserted into the vein under direct vision. It is used for venous access in cases of trauma, and hypovolemic shock when the use of a peripheral venous catheter is either difficult or impossible.
Standard catheter. 1. The catheter itself is composed of (a) a tip for insertion into the vein, (b) wings for manual handling and securing the catheter with adhesives, (c) a valve to allow injection of drugs with a syringe, (d) an end which allows connection to an intravenous infusion line, and capping in between uses.
A peripherally inserted central catheter, or PICC line (pronounced "pick"), is a central venous catheter inserted into a vein in the arm (via the basilic or cephalic veins) rather than a vein in the neck or chest. The basilic vein is usually a better target for cannulation than the cephalic vein because it is larger and runs a straighter course ...
Medical illustrations have been made possibly since the beginning of medicine [1] in any case for hundreds (or thousands) of years. Many illuminated manuscripts and Arabic scholarly treatises of the medieval period contained illustrations representing various anatomical systems (circulatory, nervous, urogenital), pathologies, or treatment methodologies.
It arises from the cephalic vein 2.5 cm (one inch) below the lateral epicondyle of the humerus, runs obliquely upward and medially, and empties into the basilic vein 2.5 cm (one inch) above the medial epicondyle. It is routinely used for venipuncture (taking blood) and as a site for an intravenous cannula.
