ABSTRACT:
An injection set for delivering a fluid to a subcutaneous injection location in a patient is disclosed which has a soft cannula projecting from a bottom surface of a holding pad. An insertion needle is initially inserted through a septum located between a catheter hub and a retaining cap mounted on the holding pad. The insertion needle extends through a fluid chamber defined by the septum and the catheter hub and then through a lumen of the soft cannula, with the sharpened tip of the insertion needle extending beyond the end of the soft cannula when the insertion needle is fully inserted. The insertion needle, which allows priming of the injection set, may be removed following installation of the injection set without kinking of the soft catheter, and fluid may be supplied to the injection set for delivery to the patient.
