HtS - the cannula. I use the Accu-Chek FlexLink, which has an inserter doodah Have a look at this page which describes it and has a comedey video of how it's used. http://www.accu-chek.com.au/webapp/wcs/stores/servlet/Product_303_303_-1_50941_302_302_302_Products
In practice, it's very easy - push the top down, pop the new canula in. Remove the protective sleeve around the needle and expose the adhesive. Pull the top away from the bottom - hold against skin, press the button. The actual insertion doesn't hurt (I've barely felt it so far). Next press the adhesive bit down, remove the needle and cap thing, the connect tube from th epump.
