Specially designed for those who have difficulty injecting themselves manually with a syringe. At the touch of a button, it automatically inserts the needle and contents of the syringe into the skin without the user having to see the needle. Available in two models, for either fixed or non-fixed needle syringes, features adjustable penetration depth, a safety lock to prevent accidental firing and a dose completion indicator. The one-handed operation makes it possible to use a wider range of injection sites than manually injecting with only a syringe.
