Abstract
A subcutaneous injection set is disclosed of the type having an insertion needle for quick and easy subcutaneous placement of a soft cannula through which medication can be delivered to a patient. In one preferred form, the subcutaneous injection set comprises a base adapted for press-on attachment to the skin of a patient at a selected infusion site. The base includes a connector sleeve for connecting a length of infusion tubing to the soft cannula. The soft cannula is threaded through an eye formed near the distal end of the insertion needle which is mounted on a collapsible injector that is detachably mounted to the base. The base is positioned on the patient's skin, the injector is collapsed by pressing toward the patient's skin whereby the insertion needle pierces the skin for transcutaneous cannula placement. The press stroke of the insertion needle is sufficient to unthread the cannula therefrom, whereupon the injector can be retracted to withdraw the insertion needle from the patient. The needle carrier can then be detached from the base and discarded.
