An injector is provided for automatic placement of a subcutaneous insertion set such as an infusion set or the like used for delivering a selected medication to a patient. The injector comprises a spring-loaded plunger having a head for receiving and supporting the insertion set in a position for placement of a medical insertion needle through the skin of a patient at a selected insertion site. The plunger head includes a safety lock mechanism for engaging and retaining the insertion set during spring-loaded advancement with a controlled force and speed toward the patient's skin to transcutaneously place the insertion needle. When the plunger head reaches a fully advanced position, with the insertion set placed on the patient, the insertion set is releasible from the safety lock mechanism with minimal force to permit quick and easy separation of the injector. Alternately, in some embodiments, the injector can be displaced away from the patient's skin to separate the insertion needle from the insertion set, while leaving the insertion set in place on the patient.

[ What is claimed is:] [1.] An injector for transcutaneously placing an insertion needle of a subcutaneous insertion set through the skin of a patient, comprising:a barrel having an elongated base formed therein;a plunger slidably received within the bore for movement between an advanced position and a retracted position, the plunger including a support structure for receiving and supporting the insertion set in a position with the insertion needle oriented for transcutaneous placement upon movement of the plunger from the retracted position to the advanced position, wherein the plunger is substantially incapable of delivering a fluid from the insertion set upon movement from the retracted position to the advanced position; anda drive for urging the plunger with a controlled force and speed from the retracted position toward the advanced position to transcutaneously place the insertion needle,wherein the support structure is removable from the insertion set while maintaining the transcutaneous placement of the insertion needle.
