Medical Syringes, Reusable Manufacturers

Medical syringes are used with needles to inject liquid or gases into body tissues, or to remove from the body. Injecting of air into a blood vessel is undesirable, as it may cause an air embolism; preventing embolisms by removing air from the syringe is the reason for the familiar image of holding a syringe upside down, tapping it, and expelling a small amount of liquid before an injection into the bloodstream.
