My son is 8 years old and have diabetes 1 (and autism as well). One issue with diabetes 1 is that there is a lot of Math involved in handling it, and its very common with children that is to young to handle the math. So most children with diabetes 1 under the age of 12-14 need constant adult supervision handling the diabetes. And even at that, some of the math is to hard for adults with low math skill.

Here is the formula to calculate the amount of insulin (European style)

Insulin = Round (0.5; (BG-5)/CV + (FoodA*FACV+FoodB*FBCV+FoodC*FCBCV...... FoodX*FXCV)/FoodCV))

BG = blod glucose level (mmol/L)

CV = Correction value (varies over time)

FoodX = A set type of food

FXCV = corection value for food X, every type of food have a value.

FoodCV = Individual correction value for food

(those shorts are different for different regions)

This is how it calculated with a normal insulin pen. Worth noting that some parrents with low math skill need to stay at the hospital for weeks just to learn the math.

There is a device called a insulin pump. It generally calculate the (BG-5)/CV part as well as the general total sum of food/foodCV.

But that still leves the:

FoodA*FACV+FoodB*FBCV+FoodC*FCBCV...... FoodX*FXCV

And this is kind of the hardest part, because it also needs a reference checkup table.

This is done by weighting the food and multiplying it with value of each food, then adding it to the next one. Worse of, this is a decimal value, so for people that is low math skill, generally really have a problem with this part.

Example dinner

Boiled potatoes: 100g*0,25=25g

Meet balls: 50g*0,08=4g

ligonberry jam: 20g*0,4=8g

Skimmed milk: 200g*0,05=10g

Cocco poweder: 10g *0,8=8g

55g

So what is needed for pretty much all people with diabetes 1 is a scale that does this calculation for them. Anyone how think this math is easy.. try to get a 8 year old to learn it. And it have to be correct every single time.

So i was thinking of a solution to this problem. A special scale for people with diabetes.

The scale will ned the following parts.

2 or 3 row digital digit read out

A analog nob that goes from 0 to 100% (or from 0 to 1) in increments of 1% (or 0.01)

A Tar button (that also clears the buffert)

A Add button, that ad to previews value and also tars the scale (but not clearing the buffert)

Possible adon, a register for food

**First question**... is anyone aware of a product that already exist that does this.

**Second**... if it not exist. Is there any resonable easy way to modify a existing scale to do this

**Thirdly**... is there anyone here with diabetes or a child with diabetes that is interesting of the project.... I would do i my self... but well i have two children with autism and one with diabetes.
