bubble inside insulin

[tracey w]

oooh i dont know what to think now lol, i think im going crazy sometimes, was so sure about the ball bubble thingy, i swear i wont rest until i remember!

is it a bubble or a clear ball in the insulin??? i have novorapid and mine all have a clear ball in them (looks like a bubble) but never goes with an airshot aimed upwards.

I've had some insulins in the past where the cartridge has a small glass bead to mix the insulin, as it is a combination of insulins. I had to invert it several times t make sure that the insulin was properly mixed. My Novarapid doesn't have any sort of ball in it (just checked), but I occasionally get a small bubble. The difference is that a bead will roll down to the lowest point, a bubble will rise up to the highest point. So, holding the pen, needle up, and tapping it with a finger nail (for best impact to dislodge it) as Katie suggested. Then, the air-shot will send the bubble out into the world, and no risk of sending it into you!

Ancient thread alert!!! 11 1/2 years old, hopefully they have sorted it by now! Dates are at top left of each post.

In the distant past insulin came in vials (mine still does), needles were longer and sringes were made of glass and were heavy. One injected the same volume of air as the tequired does to keep the pressure inside the vial constant. Any air drawn into the sringe was sxprlled by holding the sringe needle upward with the vial still attached and flicking the sringe with a finger to make the nubbles of air rise. Tje air was then injected into the vial and the dose adiusted.

One did not push the whole length of the needle into the skin. The pharmasis insisted that I did not need long needles and point blank refused to supply them.


The first time that I used the new length, as soon as I flicked the sringe, rhe vial flew off the shorter needle. I now need three hands one to hold sringe one to hold vial amd one for flicking.

I imagine that a similar flicking process could be applied to more modern equipment.

Why is there a bubble there? I imagine that it is because air is cheaper than insulin!

Oops! Note to self - make sure I'm awake when looking at threads LOL.

Thanks for the reminder, @silentsquirrel , and thanks for the story @leonS . I never used the glass syringes - I launched straight into the plastic ones, but well remember the phials of Insultard all those years ago (and 12mm needles for me ...)

It's ok it happens frequently.

LOL ! I can't flick to get bubbles to the top, hurts my ruddy finger every single time. Hence, I utilise either a substantially cased ballpoint pen (another thing my Parker Lady ballpoint pen was useful for as well as the noughts flowing from its tip) or a piece of cutlery which are always in the same drawer so easily to hand, to 'bash' the side of the syringe/pump reservoir with. Very reliable method. Viners Profile table forks and dessert spoons are good, but the table and dessert knife handles are too heavy. And uncomfy to hold the blade to utilise very often too! 😉
