my cartridge reservoir holds 315
my pump trainer told me to change out the whole lot every 6 days. and change just the cannula every 3 days.

by the 6th day i still have a half cartridge left, so instead of changing it i just pop a new cannula in and carry on for another 3 days.

i dont have any weird highs towards my 9th day. and the insulin still looks good and clear.

how often should we really be changing the insulin cartridge?

any comments are appreciated ;)
Sharon :)

I usually change it every 3 days, I take about 70 TDD, so I can almost get 4 days. I have also just refilled the cartridge and put it back in and just change my set, a couple of times.

My cartriage will hold about 300, but I don't even use 40 units a day, so I only fill it up about 1/3 of the way (change everything out every other day). I have the MM722. Let the nurse talk me out of the MM522.:mad: She said I would be happier with a pump that holds more insulin, but I should have listened to my instincts. The fact that the 522 is smaller frustrates me further. Oh well, I know better for next time.:)

I change mine with my infusion set. The Animas holds 186 units and I use roughly 60 units a day so it works out perfect.

I sometimes use the cartridges twice as I like to save waste, however, now I have 3 times as many cartridges as infusion sets somehow from doing that.

When I started pumping I asked my diabetes educator about this. I was filling up the entire reservoir to 180 units (well a tiny little bit under actually). I hated having to waste insulin so that’s why asked the DE about not changing the reservoir on the third day...
My educator said I need to change the reservoir when I change the site but you don't have to fill it up all the way- just what you'd use in 3 days.

I think you are ok not changing it regularly. I change mine whenever it runs out. I change my set every three days or less. Sometimes they coincide. MM had mixed sets too where only half in the box have tubing. I think $ for some would definately be an issue. Get the most use you can.

Virginia Woolf: “Consider how common illness is, how tremendous the spiritual change that it brings, how astonishing, when the lights of health go down, the undiscovered countries that are then disclosed, what wastes and deserts of the soul a slight attack of influenza brings to view, what precipices and lawns sprinkled with bright flowers a little rise of temperature reveals, what ancient and obdurate oaks are uprooted in us by the act of sickness, how we go down in the pit of death and feel the waters of annihilation close above our heads and wake thinking to find ourselves in the presence of the angels and the harpers when we have a tooth out and come to the surface in the dentist's arm-chair and confuse his "Rinse the mouth-rinse the mouth" with the greeting of the Deity stooping from the floor of Heaven to welcome us - when we think of this, as we are so frequently forced to think of it, it becomes strange indeed that illness has not taken its place with love and battle and jealousy among the prime themes of literature”

When I was on the Disetronic pump I only changed out the cartridge when I had 20 units or less left, usually every 5 or 6 days. I've never heard of changing it out every three days. Interesting.

my sets are boxed with half with tubing and half without too.
i suppose its not too much of an issue whilst the weather is chilly, but maybe when it gets hotter in the summer (yeah we can dream here in the uk!) i could switch to every 6 days for a cartridge change.
its interesting that some of you change out the whole thing every 3 days.

I have always changed the reservoir and tubing together. Usually once every 5 or 6 days, but I never go below 5 units in the reservoir. Does anyone use the extra plastic cap that is included with the Quick-Set?

I use about 60 units TTD, so my MM722 won't hold enough to go every other set change. I do change the reservoir with each change, but I have reused the cartridge on occasion.

Markr - I toss the plastic cap that comes with the set - I think that most folks here do too from what I remember...except for some who swim.

My MM 522 will last me 5 days so that is when I change the resevoir. I use my resevoirs twice then toss them out. I change my set out every 4 days and change the tubing out when I fill the resevoir. I have let mine go down below empty and there is still a little in reserve so it has never been a problem. I will only go maybe an hour or so then change it out. I did not need the 722s big resevoir so I got the 522. Working fine with it.

If I take of my pump for an intimate moment with DH, I will place one of those caps over the set, so that the hub, does not scratch or rub one of us wrong,:T

i put enough insulin in the cart to get close to 6 days (maybe as much as 8 days). I try use as much as I can before I change it. I dont bother trying to line it up with an infusion set change - they are like two seperate things for me now.

I also like running the battery down till there's one tick mark, and the little almost empty icon shows.
