These are pen-like insulin delivery devices. They look very similar to an insulin pen, but do not have a needle. They deliver a small jet of insulin under high pressure at the push of a button. Once it is loaded to the desired dose, it has to be placed at the site against the skin. The trigger should then be pressed. This changes the insulin into a vapour form that penetrates the skin. Within a second the insulin gets into the subcutaneous tissue under great force.
Thus, unlike a pen, there is no puncture of the skin involved, and this insulin is delivered in the subcutaneous region. Certain cleaning instructions have to be strictly followed to maintain sterility. The jet injector should be cleaned with a damp cloth from the outside. This device should also be stored at the desired temperature.
