Abstract

Objective: Pump size exterior artificial pancreas that will keep the glucose between 120-150mg/dl.

Method: The whole project based in idea that we should already know one insulin unit how much is able to go down the glucose and one glucagon’s unit how much is able to increase the glucose. Less than 120mg/ dl it uses glucagon’s. More than 150mg/dl it uses insulin. The pump checks the glucose automatically every 8 minutes. The pump (which is software decision) will choose between insulin or glucagon’s base in internal database table with prerequisite glucose values and the insulin or glucagon’s units requiring for each glucose value (adaptive database table for each diabetic). The pump (the software) is able to choose how many insulin or glucagon’s units it should use (that is not based on what the diabetic will eat, but base on the current glucose level that received from the sensor which is located in human body, needle and sensor are one piece). The insulin should have work duration 8 minutes and works instantly.

Result: I chose 120mg/dl as the lowest allowance glucose level because this glucose level is secure for the diabetic (there is a time to prevent big hypoglycemia).

Conclusion: This project offers to diabetic’s insulin injections freedom, hypoglycemia prevention, run emergency tests, ideally for all ages, endocrinologists will have the software to adapt the internal database table of the pump for each diabetic needs.
