The 17th Congress of the International Diabetes Federation was held in Mexico City in November 2000. Several interesting new products were shown.
- Roche demonstrated the Accu-ChekTM D-TectorTM, a non-invasive, optical sensor for the detection of undiagnosed Type 2 diabetes. The Accu-Chek D-Tector measures the fluorescence in the crystalline lens of the left eye using an eye-safe blue light. The fluorescence is associated with the amount of Advanced Glycation Endproducts (AGEs) present in the lens. AGEs build up at a faster rate in people with diabetes, and with advancing age. AGEs posses distinctive absorbance and fluorescence properties, which are measured by the D-Tector. Fluorescence levels above a threshold may be indicative of undiagnosed Type 2 diabetes.
The entire testing process takes about 30 seconds. After placing your head against the instrument, you watch a red dot in the field of vision of your left eye. Once you're properly positioned, a blue light shines into your left eye for 15 seconds and the D-Tector measures the fluorescence. A numerical result is displayed immediately.
The D-Tector is an investigational device and has not yet received FDA approval.

- Roche demonstrated the Accu-ChekTM Compact, a new blood glucose monitor that uses a 17-strip cartridge in the shape of a small drum instead of individual test strips. Each drum is about the size of three or four Lifesaver candies stacked on top of each other. The drum is inserted into the meter, and the meter reads calibration information automatically.
Pressing the "On" button causes the meter to move a test strip into position automatically. The strips suck in the 3 microliters of blood and tests are completed in 15 seconds. The Accu-Chek Compact stores 100 glucose readings and has an infrared data port interface.
As of November 2000, the Accu-Chek Compact is not yet available in the United States.
- Novo Nordisk demonstrated the Innovo insulin delivery device. Basically an intelligent pen, the Innovo uses 3ml insulin cartridges and has a built-in memory that indicates the last dose and time elapsed since the last dose. Dialing in the dose is very easy, and the large LCD display clearly shows the amount of insulin to be injected. Dosing is in one-unit increments, from one to 70 units. When injecting, the Innovo shows when the complete dose has been delivered, waiting six seconds after the last unit of insulin is injected to ensure that all insulin is delivered.
The Innovo comes with one of two accent colors -- orange or green -- so that people who use two types of insulin can distinguish between the types.
