This instructable demonstrates something I had to learn by trial and error for my son who has Type 1 diabetes and uses a Deltec Cosmo pump.

Note: This instructable requires prior knowledge of needed amount of insulin in the cartridge.

Caution: The top of the insulin vial must be cleaned with an alcohol swab before beginning. Care must also be taken while handling the needle.
