Minimed already has a pump that will turn off when the blood sugar hits 50. It is already on the market. That is very different from a pump where basals are automated based on reading from the current Dexcom sensor. Aside from ??? a good part of the night, Dex has been WAY off... and at times when the sensor had been working reliably. Drifting. Recalibration fixes it. But the pump would deliver insulin based on the faulty readings. Since I believe a computer could figure out basals much better than I can and in real time, the only real drawback for us is the reliability of the sensor readings. If there is any way to get around this, either by frequent testing (not good enough), or if they came out with tiny multiple sensors using the microneedles so it would not be invasive, I think we would try it. But even if the pump worked most of the time, only one large erroneous reading could be dangerous. The pump with a separate chamber for glucagon.... that is not the pump they are talking about marketing in four years. Yes, I would feel so much safer with a pump with dual chambers, one for glucagon and one for insulin.
