AUTOMATIC INJECTING SYSTEM FOR BLOOD-GATHERING AND VEIN INJECTING

摘要

An automatic injection system is provided to accurately inject a needle to an optimum place of an intravenous vessel for sampling blood and injecting medicines of a constant quantity through the needle injected into the intravenous vessel. An automatic injection system includes a sensing member radiating near-infrared ray to a user's arm portion for selecting an intravenous vessel, an image member converting reflected waves of the near-infrared ray into an image signal, a micro processor processing the image signal received from the image member and selecting an optimum intravenous injection, a needle drive member for inserting a needle into the intravenous vessel by receiving the control signal from the micro processor, and a needle extracting member for automatically eliminating the needle from the intravenous vessel.
