I bring a challenge to glucometer makers, make a meter that is so simple to use that a patient does not need instructions prior to using it.  (Glucometer is a trademarked brand of the Bayer Company but is also used generically to refer to all types of blood glucose meters). 

The problem.
Your current meter comes in 4 parts.  The meters are designed to be smaller but after you add all four parts up and put it into the carrying case, it’s not so small after all.  The parts are:  The meter, the test strips, the lancet device and the needles (or lancet).  Why can’t you make all these things into one device?  Do you not realize how hard it is to explain to a 75 year old patient how to take his blood sugar?  He has to first clean his hands.   Load the needle into the lancet device.  Poke himself with the needle.  Put the test strip into the meter.  Align his fingers into the strip and draw up enough blood.


I don’t understand the marketing reasoning behind such difficult testing techniques.  If you only design a simpler device, you’ll have people testing them three to six times daily and you’ll get more profit!

There have been some breakthroughs on the technology of blood glucose testing.  Some of which includes infra-red readings and plasma readings, and both of which are non-invasive.  The later refers to a device which the patient would wear like a watch.   The device draws out the plasma (the watery part of the blood) from the blood, through the skin and into the device.  A laser beam is then passed through the plasma to determine the glucose content.  Unfortunately, such technologies are not quite perfected yet.  Historically, testing techniques that do not use whole blood (including the red blood cells part) is not an accurate measure of one’s blood glucose measure.  In the plasma example, what is making the test less accurate is that as the plasma passes through your tissue and skin, it picks up more glucose/drops some off and the reading is not adequate.  

To reiterate my challenge.
Make a simple device that a patient can put to their finger, press a button, and the device does the rest of the work to get the reading.  This would include pricking the skin and retrieving the blood.  And please….do away with the calibration business.  Why does a patient need to punch in the numbers on the bottle when it could be printed on the test strip and read by the meter.

Thank for your dedication into making this device.  I promise to tell all my patients (my dad included) to use it and all my contacts to recommend it. [if it’s good that is]
