Insulin pump simulator in telegram bot format
The insulin pump simulator as a desktop application, which did not arouse interest among the general public, determined the need to look for another format. A telegram bot in Python was chosen as a new format. In doing so, we had to sacrifice some of the functionality, but this simplified the process of starting to work with the simulator. But first things first.
The main goal of the development is a simulator for selecting insulin therapy settings with a feedback response in the form of a glucose value.
For navigation in the bot, a menu has been developed, presented below
The first task is to develop a patient generator. Generating this data using a random number generator is a working idea, but it is far from reality. After all, in medicine, the ratios of all the interrelated parameters that characterize a patient have long been formed: age, weight, daily insulin dose, UC (carbohydrate ratio), FSI (insulin sensitivity factor), BP (basal profile/basal rate). Let's use the known ratios and teach the future bot to generate patients with “adequate” parameters. Below is the code for the patient generation module.

Based on the description, the user can determine the approximate coefficients of the UC, FCI and BP. This description is available at any stage of the task by clicking on the “About the patient” button.
The “Info” button, the code for which is presented below, is designed to display current information about the simulator state. This information allows you to track changes in glucose, view current settings and the value of glycated hemoglobin for the simulation period.

A detailed calculation is available to the user. In this case, the calculation is carried out in accordance with the values of the UC, FCI and BP set in the simulator.

!!!This bot is intended solely for testing and determining the relevance of the development and cannot be used to determine pump settings or the amount of insulin without a doctor's recommendation!!!
This bot is currently available for testing.

In the comments, please describe your vision of the problem and possibilities of this format for educational software.
As a direction for further research, I would like to add checking the correctness of the selection of parameters with the output of information about this to the user, maintaining statistics on the number and speed of execution of parameter selection options, an emergency option for terminating the simulator in the event of a glucose value of less than 2 mmol/l or more than 20 mmol/l.
