Diabetes Mellitus with Poor Glycemic Control as a Consequence of Inappropriate Injection Technique

Figure 1

Illustration of insulin delivery during faulty injection technique. Numbers 1–5 demonstrate each of the highlighted steps of the delivery. The cartridge plungers in red and grey are basal and premix (30/70) insulin, respectively. In steps 2 and 3, two yellow lines represent the gap between screw (black) and cartridge plunger (grey) during delivery while a single yellow line represents no gap (steps 1 and 4-5). Details of the figure have been mentioned in the Discussion.
