How are blood glucose monitoring modules installed in arms?

[berkeman]

My wife asked me a good question, and even with moderate Google searching I couldn't answer her question about how the patches are installed in arms. How do these BGL monitoring patches work? Thanks.

Here is something I found here:

It says they put a wire under the skin.
Sounds like a possible path for infection to me.

It is called continuous glucose monitoring, CGM.
Explanation:
https://www.niddk.nih.gov/health-in...naging-diabetes/continuous-glucose-monitoring,
also called artificial pancreas.

A pin that measures interstitial glucose lives in the the transmitter. The gizmo is held in place with adhesive that your can replace. If you have a pump that can receive signals from the CGM, then you get small doses of insulin - like Humulin - periodically until your glucose level is under control. There is an app for it. This is the basis of an artificial pancreas.

I do not know how glucagon is delivered if it is at all.

Can you tell I have two adult kids who have screwed up their bodies doing free form diabetic control?

One is now wired in. She is doing well. The other one was so screwed up that a pancreatic + kidney transplant was done. Now he is completely housebound because of immunosupression. But he has a functioning pancreatic system. Works well.
