If I remember correctly, the glucowatch and glucoband were to warn of hypo's not as a glucose meter... Dectecting when the skin starts to sweat durning a hypo so often mislead when one was just hot and sweaty... You still had to do the BG test
There was last year a Isreali company (I think) that was going through the process of licencing a non-invasive device that clipped onto the ear... Not hearld anymore since..
Every insulin pump will at least log the last 50 bolus's dose, time and date...
There was a digital insulin pen that gave a digital read out of dose being inject and also gave the time and amount of the last dose, but it had many problems so was discontinued...
Apart from suggesting writting them down, the only other thing I can suggest is getting a Ultrasmart meter (lifescan) as this meter contains an electronic log book, which you can enter all your details, insulin dose ect which would enable to retrive info put in... You can download all the data to software via a cable, which cost around £11 with p+p, the software is free to download off lifescan website, which also contains links to where to purchase the cable...
