The glucometer traces its origin to 1965, when the Ames Company marketed paper strips called Dextrostix—an invention of Ernie Adams—to physicians. To use Dextrostix, your applied a drop of blood to the paper strip and waited for one minute before washing it off. The color the blood leaves behind is then measured against a color chart, which ultimately gives the person an approximation of the level of glucose in the blood. However, Dextrostix usability was limited in that blood glucose levels were often interpreted as either of two extremes: very high or very low. Moreover, they were not particularly designed for patients; it was for doctors to use in their medical practices.

In the mid-1970s, Boehringer Mannheim produced the LifeScan bG, turning bG into standard medical shorthand for blood glucose. Ames released its Glucometer in 1975, making glucometer a generic term for blood glucose meters.

In 1979, the Dextrometer, also from Ames, became the first meter available without a prescription.

From '65 to '79: 15 years. I had one of those, went on MD I (multiple daily injections) switched to 1st pump in June '81!

really need to do a history of inventions and when became standard of care to see how fast things moving…

This stuff fascinates me, where we were 40 years ago, how we got where we are now. I work in research and those are success stories. How many lives were prolonged, improved, or even saved because of that, and other product/drug developments? Drug companies; including medical device companies are an easy target with rising health care costs and everything else. Somebody believed in the need and the benefit and saw it through, with thousands of 'nerd' hours and millions in research and development, and approval by the FDA and every other governing body around the world.

I have met people who have been diabetics longer than me but you are the first that have been on a pump ad long as me. I think it was April of 81. I was 11.

+jarett88: Funny how little is done with such a powerful research group. Insulin-Pumpers has been around for 20 years or so, and some of the people there also very long term pump and diabetes. Sad thing to me is how little real progress we've made in pump development - I remember the jokes about early Mill Hill and Autosyringe pumps being used as tests of endurance —> if you lasted longer than your pump you were in good shape.

With the advent of multiple basal rates and multiple bolus ratios over the day (which really started to show up with the EUGLY and even before with the AS*6MP, there has NOT been much other than size of machine, number of alternative profiles, number of elements and settings within a profile, etc. Medtronics sensor and the pumps showing & utilizing that data a psuedo step forward as it is a tiny drop out of huge picture…

Thanks for sharing that, quite informative.

What about the development of the sticks one would dip in a tube of urine and one would get a color which corresponded to BG levels? I did that in 1995 and came up with a reading around 300. My first hint that something was wrong.
