A safety syringe with retractable needle is disclosed. The syringe body contains a hollow needle mounted on a base. An ear on the base extends through a guide slot in the wall of the body. The ear follows the guide slot and allows the needle to extend and protrude from the end of the body or be retracted back into the body after use. A front and rear lock slo t hold the needle in an extended or retracted position. Once retracted, the needle tilts to one side, thus easily identifying the syringe as used and preventing the needle from accidentally protruding from the syringe body. A vial removal knob provides easy removal of the sample vial. A rear cover closes the end of the body to prevent the rear needle tip from protruding from the body. Therefore, a high degree of safety for medical personnel and patients is ensured. |
