2 results about "Hypodermic needle" patented technology

A hypodermic needle (from Greek ὑπο- (under-), and δέρμα (skin)), one of a category of medical tools which enter the skin, called sharps, is a very thin, hollow tube with a sharp tip that contains a small opening at the pointed end. It is commonly used with a syringe, a hand-operated device with a plunger, to inject substances into the body (e.g., saline solution, solutions containing various drugs or liquid medicines) or extract fluids from the body (e.g., blood). They are used to take liquid samples from the body, for example taking blood from a vein in venipuncture. Large-bore hypodermic intervention is especially useful in catastrophic blood loss or treating shock.
