A device that consists of a syringe, a tube, a piston moving inside the tube, and a thin nozzle, sucking gases and liquids into it under vacuum and spraying them in a thin line. A syringe with a needle attached to the tip is called a needle for short. A hypodermic needle, nozzle, or tubing can be attached to the open end of the syringe to direct the flow in and out of the bucket. Syringes are often used in clinical medicine to inject, to deliver intravenous drug into the bloodstream. The syringe is also used in gardening and in the kitchen, to apply compounds such as glue or lubricant, and to draw or measure liquids.
