Picture 2
With your free hand, pinch together a bit of subcutaneous tissue at the disin-
fected site. Insert the introducer needle (C) under the skin at an angle of
20–45°, proceeding quickly and in one motion. Watch the soft cannula (B) while
inserting to assure that it goes in smoothly without kinking or crimping.
Warning
People with very small or large amounts of subcutaneous fatty tissue should take
care when choosing the angle of insertion or the cannula length. The cannula
could be lodged in the muscular tissue or epidermis, where absorption of the
medication is limited or impossible. Ask the doctor who is treating you about this.
Make sure that the soft cannula is fully inserted into the subcutaneous tissue
and not kinked at the skin surface.
Once the introducer needle punctures the skin, the soft cannula must be quick-
ly pushed in the rest of the way, or it may kink upon insertion, causing reduced
or blocked medication delivery.
