Nurses regularly had trouble putting in the cannula in my husband's hand as they couldn't find a vein. Several attempts would leave his hand bruised plus it wasted a lot of the nurses' time. I bought two lavender/wheat bags. I sewed one of the bags in to two halves then attached elastic to each piece so they would fit round his hand. Before we set off to each appointment I heat up all the bags in the microwave and he travels with one of the bags on his hand. (Sometimes he wears a fleece glove underneath the bag if I have made the bag too hot!) I keep the other small bag wrapped in the bigger lavender/wheat bag and carry them in an insulated food bag. When we get to the hospital I swap the bag on his hand for the one in the food bag and wrap the big bag around the used one to reheat it to use if waiting times are longer than usual. It has worked well so far - the constant warmth raises his veins so it is much easier to put the cannula...
