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.

nicely documented! how often does it need to be refilled?

I refill it every two days, but some do it every three. Thanks for the comment!
