An injector system utilizes a disposal ampule or, in one instance, a disposal syringe, in all cases being characterized by "tracked" injection wherein the medicament within the ampule or syringe is dispensed as a linear function of needle penetration, and the complete injection operation is executed such that the needle is never exposed. The needle is withdrawn within the medicament chamber after use where it cannot injure anyone except in one instance, in which the needle is capped after the plunger spindle is snapped to prevent reuse of the syringe. The objectives of the improvements are comfort to the patient, ease of use by the administrator and safety for all involved.
