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.
A subcutaneous injection set, comprising: a one piece housing defining an internal chamber adapted to receive a selected infusion fluid, and further defining a generally cylindrical support hub having an outlet bore formed therein and a generally annular seat surrounding said outlet bore at an upstr
A subcutaneous injection set, comprising: a one piece housing defining an internal chamber adapted to receive a selected infusion fluid, and further defining a generally cylindrical support hub having an outlet bore formed therein and a generally annular seat surrounding said outlet bore at an upstream end thereof within said chamber; a cannula having a base end defining a radially outwardly extending flange, said cannula being received within said outlet bore with said flange generally overlying said annular seat, said cannula protruding outwardly from said housing; sealing means interposed between said flange and said annular seat; and a radially inwardly extending annular lock rim swaged in the interior of said housing and overlying at least a portion of said flange to retain said flange in a position relative to said seat to compress said sealing means.
