They worry about insulin pumps outdoors in sunshine or hot weather, which would seem pretty much what you were in there?jas88https://www.blogger.com/profile/05563592458314214904noreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-61833012065519054922017-09-18T14:14:07.424+01:002017-09-18T14:14:07.424+01:00Pulled for hand search like, say, a coffee grinder...Pulled for hand search like, say, a coffee grinder.

The only downside to it is that you have to remember to scan rather than getting real time notifications. People have done some interesting reverse engineering of the product and from what I can tell it mitigates inaccuracy of individual readings by averaging samples over a 15 minute interval. http://type1tennis.blogspot.co.uk/ is good reading.Technical Vaulthttps://www.blogger.com/profile/06706968838212709673noreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-9617282755043205362017-09-18T11:26:11.565+01:002017-09-18T11:26:11.565+01:00I wonder what airport security/scanning would make...I wonder what airport security/scanning would make of that?jelvhttps://www.blogger.com/profile/06330649794336059930noreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-57893452021618751422017-09-17T13:00:42.390+01:002017-09-17T13:00:42.390+01:00Would the pen not fit inside a thermos flask?Would the pen not fit inside a thermos flask?Alrockhttps://www.blogger.com/profile/05036824899611637886noreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-88629538562250924982017-09-17T09:29:11.664+01:002017-09-17T09:29:11.664+01:00Phoebe uses the Freestyle Libra CGM, makes a big d...Phoebe uses the Freestyle Libra CGM, makes a big difference and allows better analysis.SimonFhttps://www.blogger.com/profile/03711861360301638111noreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-69489222291588671542017-09-17T09:14:02.332+01:002017-09-17T09:14:02.332+01:00I know what you mean, I am sure I had a bad batch ...I know what you mean, I am sure I had a bad batch once, but in this case the working pen was from the same batch.<br /><br />CGM does look interesting.RevKhttps://www.blogger.com/profile/12369263214193333422noreply@blogger.comtag:blogger.com,1999:blog-3993498847203183398.post-23457488662855958442017-09-17T09:04:32.443+01:002017-09-17T09:04:32.443+01:00Perhaps you were unlucky.

The picture is of a pre-filled disposable, and I no longer use pre-filled disposables as I had a similar bad experience on a US trip many years ago. I discovered that all the pens I had taken were not effective. They must all have been exposed to high temperature before I received them. <br /><br />Research since then shows that wholesalers are not specially careful with insulin, especially in the delivery to your pharmacy and now, in hot summers, I feel I need to be careful! I also moved to cartridges, to make it easier to carry more spares from different batches. I use two insulins (basal/bolus) so I carry a lot anyway and carry syringes too.<br /><br />Have you looked at CGM? The Freestyle Libre system has just been approved on the NHS. I have been using it recently and it does help in travel situations, although it gives some issues at security.Johnhttps://www.blogger.com/profile/14600925378443421731noreply@blogger.com
