Myself attempting a self-infusion with a shielded IV catheter (retractable catheter).
The metal needle is wrapped in a thin tube of plastic that must be inserted into the vein using the metal needle. Then the metal needle is retracted. Connect the tube with the syringe to verify proper insertion (when blood comes back out). All using one hand. ;)
Oh, and I must say it is quite nerve-wrecking doing this yourself. Finding that one vein and then sticking the needle in. You can tell how by how long it took me to actually poke myself. :/
For those wondering, I have X-linked Agammaglobulinemia. If you're curious as to what that is, just Google it (or "XLA").
