  "title": "How a Computer System Automatically Adjusts Blood Sugar in Real-Time",
  "original_title": "Computerized system for blood chemistry monitoring",
  "summary": "This patent describes a computerized system that continuously monitors a patient's blood glucose and automatically adjusts insulin and dextrose delivery to keep blood sugar levels stable, especially for critically ill patients.",
  "what_it_does": "The system works by using a glucose sensor to measure a patient's blood sugar level in real-time (Claim 1). This information goes to a computer processor, which calculates a running average of the glucose level (Xa) and tracks how fast it's changing by comparing it to a previous average (Xb). A \"glucose control module\" within the processor then uses this data, along with previous insulin and dextrose flow rates, to categorize the patient's current glucose situation. Based on this category, the system sends signals to a pump to precisely adjust the flow of insulin and dextrose into the patient's bloodstream, aiming to bring their glucose level back to a normal range (Claim 1). For example, if a patient's glucose is rising rapidly, the system might increase insulin delivery and decrease dextrose.",
  "what_it_does_not_cover": [
    "Does not cover systems that only monitor blood glucose without automatically adjusting medication delivery.",
    "Does not cover systems that adjust blood chemistry other than glucose and osmolality, or use medications other than insulin, dextrose, and hypertonic saline.",
    "Does not cover systems that rely solely on a single glucose reading without calculating a running average (Xa) and its rate of change (Xa vs Xb).",
    "Does not cover systems that do not categorize the patient's glucose status based on the specific factors listed in Claim 1 (difference from normal range, rate of change, previous insulin/dextrose rates).",
    "Does not cover manual adjustment of medication by medical personnel based on sensor readings."

  "abstract": "An apparatus and computerized method of intravenously monitoring a patient's blood chemistry transmits real time measurements to an electronically controlled closed loop system that auto-regulates blood osmolality and glucose level with medications infused through a catheter designed for such purpose. The closed loop system utilizes a glucose algorithm and an osmolality algorithm implemented in hardware and software to control the flow of dextrose, insulin and hypertonic saline to a patient in an effort to achieve better patient outcomes in instances of trauma, surgery and medical illnesses.",
