Artificial Pancreas Assistance

Other Hardware Robotics

Hi,

I am planning to create an artificial pancreas using an Arduino, Glucose sensor and an Insulin pump. I plan to programme the arduino to read a certain value from the Glucose sensor and if you high then activate the pump. When the glucose levels fall down due to the insulin the value will also fall and when below the 'Danger' limit I plan to programme the arduino to stop the pump. Whilst all this goes in the glucose sensor will continously measure sugar levels and relay these to the arduino which will in turn relay them to a PC.

My question is..... Is this all even possible? Or am I thinking too much for the arduino.
Also, What Arduino board will be best and how many will be required? Any other sensors or materials required?

Thanks in advance.

Given how little you know, don't.

What is that supposed to mean? How do I know too little?

Sounds like something an Arduino can handle. Start with an Uno, can make it smaller later, i.e. Nano, or Micro

or perhaps a custom board combining the uC, sensors, and pump driver.

Need to know the interfaces to the meter and the pump to advise on other materials. Are they 5V compatible? How much current do they need?

Hi,

When the glucose levels fall down due to the insulin the value will also fall and when below the 'Danger' limit I plan to programme the arduino to stop the pump.

I would monitor the rate, not the level of drop in blood sugar, likewise the rate of rise in blood sugar.
Stopping the insulin when the danger level has been reached, is too late, there is a delay even with insulin pump injection and system reaction.
I hope this is a proof of concept prototype, as controller manufacturers do have limitations on performance of their products, medical applications is one of them.
