Abstract
An improved subcutaneous injection set is disclosed which has a soft cannula for subcataneous delivery of a selected medication to a patient. The cannula is supported by and protrudes outwardly from a cylindrical support hub of a housing adapted to receive the selected medication. A flanged base end of the cannula is disposed within the housing and is captured by a swaged lock rim to retain a sealing gasket under compression against an annular seat within the support hub, thereby preventing leakage of the medication through the hub and about the exterior of the cannula.
