How to Load a Cartridge Into a Deltec Cosmo Pump

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.

Gathering Materials

Gather materials: the pump with cap, the cartridge, the infusion set, and the tubing

Filling the Cartridge

Attach the needle to the cartridge by twisting into place clockwise and remove lid Do not throw lid away.

Pull air into the cartridge to the desired setting, creating as precise a measurement as possible. The air will compensate for the insulin to be removed from the vial and prevent the creation of a vacuum. A vacuum may cause the vial to break, causing injury.

Insert the needle into the spongy center of the top of the vial as shown

Push the air into the vial

Pull the insulin from the vial into the cartridge as shown, farther down than the setting in step 1

Thump the vial with your finger to bring the air bubbles to the top of the cartridge

Push the plunger up to remove air bubbles, thumping again if necessary

Return plunger to setting in step 1
