I rather think anyone with half a brain would do that, TBH.

However I do of course realise that they must also cater for those who haven't!
 
I would hate to think my kids were away from home & had that pump ??
 
Well hang on Hobie - the Combo and the Insight, both alarm -for instance - in the middle of a bolus or whatever else they happen to be doing, when the cartridge is getting low - the Combo was 20u, I have the Insight set at 10u now. So as and when - I always check on the Pump history after, to make sure the whole bolus has gone in.

Do other pumps not alarm for any reason?

Isn't it just part of learning how to operate whatever pump you happen to have? if they were little kids then I'd expect boluses to be supervised by the 'responsible adult' anyway same as they would for MDI. So the designated adult would need to know what to do when the pump alarms, it's no different from his dad knowing what to do!
 
I would hate to think one of my children were on a weekend break away from me & something happened with a faulty pump ?

Then best give up pumping then or never allow a child out of your sight HOBIE as Medronic have a dreadful record with alarms/faults etc., with other pump companies in hot pursuit.

You have to remember the pump is a mini computer and they go wrong on occasions, hence why all pumpers are given strict instructions regarding carrying backup supplies.
 
Well exactly Sue - that's exactly why I not only carry pump supplies but also a packet of syringes with me. (far easier to carry syringes than get scrips for all the garbage required for pens)
 
I have been using a Medtronic pump for more than 9yrs. No problems with both models. I will say again "I would not like to think a child of mine had a pump that was not up to scratch"o_O

I don't think this is a problem with the actual pump, it's a problem with how some people react to the error messages, so they feel it needs clarification 🙂

Then you have been very lucky not to have needed a pump replaced. Perhaps if so concerned about the potential danger to children it might be a good idea to keep all children on pumps locked up at home or even write to the health sectary and suggest no child should have a pump just in case it goes wrong!
 
Never needed to have replacement pump sue, Did you read the title of this thread ?

Yes I did read the title and you were implying that the Medtronic pump was perfect, which it certainly is not.
 
We have had a couple of issues with the Combo Bluetooth dropping out just at the point when the bolus is due to start, so then you don't know if the pump has received the message or not. Took me a while to work out how to check definitely whether the bolus has happened or not (and of course since then we haven't had the problem again lol). I can't follow my daughter everywhere though and certainly am not going to take the pump off her when she can't be with me! Problems are rare and so I have to just hope that either it won't happen or that she'll use her brain if anything does go wrong. If she goes hypo she'll deal with it. If she didn't know whether the bolus had succeeded I think she would wait a while and then test and correct if she'd gone high. Any adults in charge always ring me if they have any problem that they don't know how to sort out themselves.

I think it's very unlikely that we will choose the Insight as our next pump given all the bad press, but just because we haven't got that one doesn't mean we won't have a problem! Someone on here (Flower?) has had two Medtronics waking her up in the small hours with pump delivery failure, which meant that she needed a new pump. So they aren't infallible either Hobie! Nothing is perfect, but pumps are the best thing we have at the moment and I want my daughter to have the best, sometimes you have to take the rough with the smooth o_O
 
"I love my pump " & have never had a problem with it or the previous Medtronic 🙂
 
Sue and others were only pointing out that you are the exception Hobie - not the rule. Lucky old you - but don't assume everyone else is automatically going to be that lucky - because they are simply - not!

When things are manufactured out of a pile of different bits and pieces - it's almost inevitable something will go wrong with some of them at some time!

"To err is human", after all ! - so even if the pump - or car - doesn't go kaput of it's own volition - very often add the human to the machine and they'll make it go wrong by doing something daft at some time, and break something on it anyway - even if it was perfect when it left the factory!
 
I think all pumps have these kind of warnings issues every now and then - I've certainly had several issued by Medtronic over the past 5 years (and all of those seemed to be largely "Well duh! You just need to pay attention to what the pump is saying" things too).

One thing I didn't like with the Veo (and I'm not sure if the 640G is any different was what happened when you ran the reservoir almost empty. I tend to use 'low reservoir' alerts as my set change reminder, especially on the Veo where there was no other automatic option, which meant occasionally I ran the reservoir rather lower than intended. On the Veo it would go down to the last few units and then display -.--u. At that stage (if I'd made an error of judgement and was out and about) I was never sure if basal was still being delivered, but the pump didn't give any kind of warning/no insulin left alert. Initially I assumed it was actually out of insulin as it seemed to suggest and then 'topped back up' when I'd got back home and done a set change.

Having spoken to Medtronic though - it seems there is a secret buffer zone, past the point where the pump reads 'empty' where it will still be delivering basal. Obviously they dont want people to *know* about this - or they might come to rely on it and then run things even closer to the wire and get themselves in all sorts of bother. Helpful in its way... but not very clear 🙂

I concede this was mostly a problem I created for myself... but just use it to illustrate that even when things are set up helpfully and with emergency (unpublished) buffer zones it's easy enough for users to get confused as to what is happening!
 
That's interesting... We recently had "Cartridge Empty" alarm for the first time ever. Which stops the pump - no arguing with that!
Normally we just change on the 6th day at tea time, it's usually close to or past the low cartridge alarm by then (20u). The lowest we'd ever run it down before then was 3u. Last week apparently the low alarm went off at 5.45am, daughter in her sleepy state just turned the alarm off without checking what the problem was (probably just assumed that I'd put a TBR on and had misjudged the stop time) so didn't tell me, these days 20u is unlikely to last the whole school day so if I'd known I'd have changed it before breakfast. She came home from school, had a sandwich before her dance class and then the cartridge was empty, so it was "er, ok, I'll change it now then!"
 
Ah - an excellent point with the Insight then! - you can change the 'low cartridge' warning to a lower amount than 20u - which is two thirds approx. of my TDD, so I always ignored anyway. Trouble is, subsequently forgetting you need to do it, as you say. And it varied at where it decided it was empty - could be 5 point something u or could be zero u, or any point between.

At 10u which my Insight is now set at - I can assess where I am/where I'm going in the next few hours. If that is at bedtime, I get a new cartridge out of the fridge before bed and leave it on my open meter case - so it will be one of the first things I see (after I've been to the loo LOL) next day. I don't find slinging away less than 10u raises anywhere near as much guilt as just under 20u did, LOL
 
You can change it on the Combo too, but can't do it on the pump itself - you have to have the computer software and do it that way. Which we've never managed to do - because my hubby is a stickler for always having the latest version of Windows and Roche always seem to be playing catch up, we've never had a copy of the PC software which actually works on whatever Windows version we have! Ditto the maximum bolus size - 12 units on my daughter's pump, which was obviously changed from the default 25 by someone because she was only 6 years old when she got the pump. Which is just about ok now, but only just, we have had a couple of occasions when we had to do two boluses instead of one, because it was more than 12 units. So will have to make sure that whatever pump we have next has the max bolus set a little higher!

Max bolus size is a safety issue, and I can imagine that some people might be a little gung ho if allowed to wildly mess around with certain settings, so I don't mind that one being a bit out of reach; don't see why the level at which your low cartridge warning goes off should be so hard to adjust though!

I've always worked to the maxim that "to err is human - but it takes a computer to make a real cock-up". When you put the two together, as with me and the pump, you can make a jolly good mess. I'm still here though.
