I use a Paradigm 722 and 3 ml reservoirs. Lately I've been getting "No Delivery" messages constantly. Many of these times it's due to a pressure problem in the reservoir (too much pressure in the reservoir and the rod can't push the O ring up and deliver insulin). I know this to be the case because I typically will run a 5 unit prime and will get the "No Delivery" message quickly. Thus I know it's not a plugged canula. Does anybody know how I can alleviate this issue (besides following the instructions in the reservoir box which I've done many times)? Any tricks I should know about getting my insulin into the reservoir without creating a pressure issue?

all i can think of besides contacting MM is fill the res. with no air pressure meaning when you fill it if you would let the piece go it would suck the insulin back into the bottle other then that there might be a issue with your pump..
and try a new box of reservoirs also maybe you got a bad batch.. or maybe its the set the needle isnt going in the res all the way..
I have had " no delivery " ONLY after priming the new infusion set tubing ( at about 2 plus units ) ...and my problem has always been : I did not connect the tubing part correctly to the reservoir ...in other words the " click " sound was missing ...Would this make sense in your particular case ??
yea i agree.. thats why im thinking he has bad reservoirs or infusion sets... because the only way i can see it no ejecting insulin is if the needle isnt in the reservoir..
It's not a connection issue. I always hear the "click". I don't believe it's the reservoirs as they are new and I've tried several over the past few days. The infusion sets I'm currently using are "replacements" from MM and it's possible that once again, they've sent me a bad batch. I just spoke with them again today (the 3rd time in less than a week) and they're sending me out a variety of new infusion sets. The only other thing I can think of is switching from a 6mm canula to a 9mm canula as I have some 9mm canulas kicking around. Perhaps it's my body composition. Not sure what to do at this point. I'm currently using Quick-Set infusion sets. Other than that maybe MM will have to send me a new pump eh? Or lastly, maybe I can just "quit" being a diabetic lol!!!

I just replied to another post of yours. I think it might be a combination of things. David started pumping at age 14. The biggest problem was "no delivery" alarms. He gave up using MM quicksets and went to silhouette. If you are running into muscle on a short quickset, that might be the problem. He is using the shortest silhouette 13mm on a manual angle. Pinch an inch and insert. That said, he increased the prime to 1.5 units to unblock new sites. You will need to test this strategy for yourself but I found that a number of Tudiabetes members are using an increased fixed prim strategy for set changes. He also had to stop hiding his pump. He started pumping at age 14 and is now 17. His tendancy was to basically wrap the tubing around and around and around, shove it down his jeans, tighten his belt and hope to hide it. The belt tightening was a big part of the "no delivery" problem. Leaving quickset, he left visibly blocked by blood sites behind and visibly kinked sites, for the most part behind. The increase in fixed prime has helped tremendously. I referred you to Nel above in these discussions for the infusion set that she uses as she is very althletic and very trim, and next time we have difficulties, we will try what Nel is using over both quickset and silhouette. P.S. 13mm quickset on an angle, seems long, but that was the comparison to the shortest quickest at 90 degrees, which if I recall correctly was 6mm.

If the feedback that you are getting does not help, get in touch with Nel, look for her above in the messages with the team canada logo.

OK!!! ive been getting this same EXACT problem for the last 3 days its the infusion set! i have 23" and 32" it happened 3 times with the 23" and none with the 32".. and ive used the same reservoir.. it wont notify me till i wake up high and have to bolus.. it will go in about .8 units then come up NO DELIEVRY! hope this helps!
I have had the same thing the last few days and I know it is because of filling last time and running out of insulin to "load".

You have to be really careful to inject only the amount of air into the bottle that corresponds to the amount of insulin you are taking out or you create a whatever the opposite of a vacuum is, in the bottle. Then it messes up when you draw up the insulin.

If you have too much air in your insulin bottle, put a syringe/reservoir in there and don't touch it - the air in the bottle will push it's way out into the syringe/reservoir until it is at equilibrium again. This would probably work better with a syringe since they are a little easier to move the plunger on.
i hope this isn't another recall. they were barely able to keep up with the last one.,,,

I appreciate all your answers above and Sunshine thanks for reminding me of this important fact. I used to know that fact many moons ago but forgot lol (I've been a diabetic too long I guess!).

I took take of this issue another way after speaking to many people including a very helpful endo in Edmonton, Alberta. Firstly, on his recommendation I switched insulin. I now take Apidra instead of Novorapid. I believe the Novorapid may have been breaking down/crystallizing and/or I had a bad batch. Secondly, I put my infusion set in the back of my arm on the endo's recommendation. This is a site I had never used. Not only is my problem resolved, but I have been on the same infusion set for 5 days (important to those of us who have to pay for our own medication and supplies)... no plugging, no clogging, no "No Delivery" messages, no high blood sugar alarms during the night to wake me from my much needed sleep! Apidra is relatively new I believe but I'm in love with it. It comes in a tall 10 ml vial and works with the reservoirs most of us would use I expect. It's also less expensive than Novorapid and possibly Humulin/Humalog although I haven't used Humulin or Humalog in quite a while. Apidra is also reputed to be better for pump users in that it doesn't clog in tubing and infusion sets/cannulas. Google it. It has me impressed.

So that's my story. I would like to think my problem was resolved by the switch to Apidra and the change in infusion sites. But one never knows with this disease, eh? I just put this story out there for you guys.

Thanks again for all your responses.
