Have you pushed air into the insulin bottle before drawing the insulin into the reservoir? Sometimes, the lower air pressure of the insulin bottle will draw the insulin back in.

We always push a reservoir of air into the bottle before drawing up the insulin. This helps pressurize the bottle, allowing the insulin to come out.

I noticed this happened to me when I was using a brand new bottle of insulin. I assumed it was because there wasn't really enough room in the bottle for more air or something, but I really don't know why it happens or how to prevent it.

Be sure to push an entire reservoir's worth of air into the bottle (bottle right side up, of course). Then invert bottle and be sure to draw the insulin into the reservoir no faster than 12 seconds, to prevent excessive amounts of air being drawn in with the insulin. Tap bubbles to top, purge about 20U (or more if you wish) back into the bottle, then withdraw more insulin to refill the reservoir. Repeat if necessary.

I am on the MM 722 Paradiam......When you get the blue cap connected to the resevoir on to your insulin bottle, be sure to pull the PLUNGER way down to the end to #3 or so.....if I don't do that right after I get the blue cap (or whatever it's called) on the insulin bottle....I find that I have screwed up...and have to start with a NEW resevoir......$$$$. After I pull the plunger way down, then I can push air into the insulin bottle, and draw down the insulin to fill the resevoir.....and then I can proceed with the rest. If I don't get that plunger way down, things don't work right ...right from the start.

"..if I don't do that right after I get the blue cap (or whatever it's called) on the insulin bottle."

it's called the "transfer guard"
