摘要：

An automatic injector/aspirator, a mechanically powered injector, medicine injection cartridges (2431) used therewith, and methods of using same to administer fluid medicaments by injection are disclosed. The injector/aspirator and injector include a chamber for receipt of the prepackaged medicine injection cartridges (2431), a rod (2440) for applying force to drive fluid medicament from the cartridges (2431) through an injection needle (2423) into a subject, and a source (2013) of such driving force. The injector/aspirator includes means for controlling the rate, direction and extent of needle insertion and withdrawal, and injection or aspiration of fluid, means for data storage and programming the injector/aspirator to predetermine and vary rates according to medically relevant factors, and sensors and indicators for monitoring performance. The force to drive a mechanical injector of the invention may be provided by release of a compressed spring (2013) or gas. Locking means (2031 and 2417) are provided for preventing accidental discharge of needles (2423) or medicine from the injectors.
