It doesn't matter which pump you use, you still can get air bubble issues..
We did a survey on the insulin-pumpers site, as one of the members does work with sastitics, so compiled the data collected..
Basic out come, was that all makes of pumps got air bubbles, they was no identifiable difference in type of insulin used, and technique helped but didn't make an over lot of difference to whether an individual suffered problems or not..
As comparing pumps..
Bolus
Most pumps now deliver the same dose, so not the issue it used to be..
Basal
Can the basal be changed every hour or every 30 minutes, this for some can make a difference in control..
Screen
Is it easy to read?
I know that the Animas has colour where as the old spirit pump not sure about the combo, has fine text and not brillient contrast, so can be difficult to read the information..
Menu
How easy is using the menu on the pump, more so if a child and other adults/carers might have to help with the pump
Wizards
Again this used to be an issue, but all the above generally include similar wizards now..
Canular's
What range of infusions set's are available, what type of locking device.. Some pumps you are totally restricted to there infusions sets due to the locking device..
A pump user a luner lock can use other manufactuer's luner lock infusion sets..
Delivery motor meginisum (sp), for most this doesn't make a difference, but there are an old few where it does, seems to be mainly those that are very insulin sensitive..
Some pumps will deliver basal or square/multi-wave bolus, continusally a screw thread type action..
Other pumps such as the spirit/combo deliver the basal and bolus in a shunt motion, a delivery every minute! i.e the programed basal of an hour will be divided equally and delivered every minute..
Main features for the above pumps
Animas 2020, colour screen
Spirit Combo has a remote control, that also include the blood glucose meter and all the wizards
Med Veo.. This incorpartes an CGM within the pump, not funded under the NHS but can self fund if needed..
Even though I can't give a report on the individual pumps, hopefully the information what I and many pumpers would be looking at in a pump will help a bit
