The invention provides a safety syringe for extracting blood, with retractable or removal needle that can be retracted into the syringe body (10) or removed after use and safety locks (19,28,141) that lock the retractable needle (31) in an extended position during use and in a retracted position after use to ensure that the syringe is not reused or that the needle (31) is not inadvertently extended. When retracted, the needle assembly is cocked at an angle identifying the syringe as used and adding further protection to prevent the needle (31) from being inadvertently extended and exposed from the tube (10). These safety features work in conjuction to enhance the usability and increase the safety of the syringe. Thereby protection medical workers from being injured by an exposed needle or contaminated by disease or infection from contact with the patient's blood present on a used needle. <IMAGE> |
