Local anesthetic injection system

摘要

A local anesthetic injection system that is suitable for use with smaller children for providing an essentially pain free injection of a local anesthesia into a child's epidermis skin layer, above nerve endings, to deaden that skin area to receive an injection of a medicine through that deadened area utilizing a conventional hypodermic needle. The several embodiments of the system include a body that has a cup arrangement with a flat edge upstanding wall and is open thereacross. The cup is arranged to receive a force applied to the top thereof to urge the cup flat edge into the surface of a section of skin whereon the cup rests, causing the skin within the cup to be formed into a dome shape. A small hollow needle is maintained within the cup such that an open bevel needle end extends at an angle just below the plane of the cup edge. Thereby, as the dome of skin is formed within the cup the needle bevel end tends to travel into the dome of skin, above the skin nerve endings, allowing a vessel connecting to the needle to dispense a local anesthesia through the hollow needle bevel end when an operator applies a pressure generating force thereto.
