A case of poor engineering
Recently, Lilly, who are one of the major manufactures of insulin, changed he design of on of their insulin pens. One would think that a major pharmaceutical company would spend a lot of time and effort ensuring that the pens work fine, wouldn’t you? Apparently not! Take a close look at the images below.
Can you see how the needle on the top pen sticks out over the end of the closed en on the bottom? Yes, if you put a needle onto the insulin pen, the needle sticks out by about 3mm, and the cap is too short to fit onto the pen. So, you either have to switch to a shorter needle, or get a new pen!
Here you can see how the cap will not fit with the needle attached.
Pretty poor design…
Two onions to Lilly!
