    摘要: An apparatus for holding a syringe and injecting fluid from the syringe. The apparatus includes a barrel having a bore extending therethrough for receiving a body portion of the syringe, a drive spring, and a telescoping piston movable under the influence of the drive spring to advance the syringe from a retracted position within the barrel to an advanced position wherein a needle portion of the syringe extends outwardly of the barrel, and to compress a plunger portion of the syringe relative to the body portion of the syringe to inject the fluid through the needle portion. After the fluid is injected, the needle is retracted back into a shielded position out of view from the user.
