Abstract
A device for use as a subcutaneous injection set is disclosed which has a soft cannula through which a selected medication can be administered to a patient, wherein the soft cannula is adapted for transcutaneous placement by an insertion needle substantially without crimping or kinking. The cannula is supported by and protrudes outwardly from a housing adapted to receive the selected medication. The insertion needle is initially inserted through a septum on the housing and further through the cannula to provide a rigid structure to insert the soft cannula through the patient's skin. The insertion needle and cannula are constructed to prevent longitudinal slippage of the cannula on the needle during the insertion process, thereby preventing undesired crimping or kinking of the soft cannula. After insertion, the needle is withdrawn from the cannula and housing to permit medication delivery to the patient.
