EASYSULIN is an insulin injection pen for children that can prevent problems caused by repeatedly injecting at the same site. Turn the morning, noon, or evening icon upward according to the time of day, and pull out the tape measure corresponding to the number of weeks since establishing the central point. The triangular design of the pen allows the injection angle for the three daily doses to be separated by 120 degrees, and the icons on the tape measure allow the injections to be separated by 1 centimeter every day from Monday through Sunday and 2.5 centimeters away from the central point to ensure that each injection is in a different place.
