How are a diabetic inmate's shots handled in prison?

My son is to surrender Friday Nov 11, 2015 He is an insulin dependent diabetic that requires 2 types of insulin, one long acting in the morning and another short acting type after he eats. He gives himself the shots. The dose of the long acting is a set dose the other shots after he eats he calculates depending on how much he eats. He also checks his blood sugar during the day to be sure he is taking enough insulin. How can this be handled in prison?
