Abstract
An injector is provided for automatic placement of a subcutaneous 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 an infusion set in a position for placement of an insertion needle and related cannula through the skin of a patient at a selected insertion site. The plunger head includes a safety lock mechanism for engaging and retaining the infusion set during spring-loaded advancement with a controlled force and speed toward the patient's skin to transcutaneously place the insertion needle and cannula. When the plunger head reaches a fully advanced position, with the infusion set placed on the patient, the infusion set is releasible from the safety lock mechanism with minimal force to permit quick and easy separation of the injector.
