Hi Janaka,
Any pump will be a million times better than MDI! They all allow you to fine-tune your basal rates, give insulin in tiny increments, use extended boluses, etc. The main advantages of each one are:
* Roche - this comes with a separate handset (which also doubles as a BG meter) from which you operate the pump by Bluetooth. This means you can bolus insulin without having to fish out the pump from under clothes/duvet etc. It can be quite handy with an uncooperative toddler, and also for bolusing a correction when they are sleeping without disturbing them by rummaging round under the duvet for the pump! On the other hand (more for older kids) there is always the risk of losing the separate handset!
* Animas - the only pump that is fully waterproof (the others must be disconnected for baths, swimming, etc.). Good for people into watersports etc.
* Medtronic - the Veo is the only pump which has a "low suspend" function when used in conjunction with CGMS (sensors) - this means if it detects a hypo and the pump user does not respond to the alarm, the pump will suspend all insulin delivery. This is a potential life saving feature in the event of nighttime hypoglycaemia, but as I say, it only works if you have sensors also.
Hope this helps! 🙂
