The spare mixed cassette I would put two of the ice packs, one on each side with a rubber band to hold them in place, I would wrap a wash cloth around this with another rubber band and put it all in another zip lock bag. I found the Flolan would stay cold for hours. The emergency bag could be carried like a purse or could go into a backpack. I had an emergency three-day pack I would put in the van. Lauren did not like to wear her pump in a back pack but rather around her waist in the back, when she sat down she would move it to her side.
Some people wear their pumps in fanny packs.
Please do not become discouraged with all of this, it is all doable. It does seem over whelming at the beginning, in time it is almost like changing your socks or panty hose, you do get the odd wrinkle but they can be worked out. We did so much with Lauren and took the attitude that her medical needs would fit into our life style. I actually did more with Lauren this past summer because we were not too sure how long she would live for. I found very interesting and unique ways to deal with Flolan, pumps, lines etc.
