A simple mechanism that provides the manipulations required to deliver a correct injection and also incorporates the saftey modifications that are needed to prevent needlestick injury and ensure self destruct capability. A surprisingly simple and cheap modification to a sterile package for the standard syringe and needle can successfully be used to automate the medical skills needed to deliver a safe injection and dispose of the hazardous needle afterwards. The sterile package consists of a housing for the syringe barrel (15), which can telescope into a larger diameter hollow cap (4) covering the syringe plunger (19). The syringe (1) and needle (3) are located fully inside this two-part packaging sheath, which completely encloses and protects them.
