Description

Method and device for managing blood sugar using a continuous blood glucose meter { METHOD AND DEVICE FOR BLOOD GLUCOSE MANAGEMENT USING CONTINUOUS GLUCOSE MONITORING }

The present invention relates to a method and device for managing blood sugar using a continuous blood glucose meter, and more specifically, to a method and electronic device for managing blood sugar using an electronic device using a continuous blood glucose meter.

Diabetes is a type of metabolic disease caused by insufficient secretion of insulin or failure to function normally. Diabetes is characterized by high blood sugar, which increases the concentration of glucose in the blood. Hyperglycemia causes various symptoms and signs to appear and glucose is excreted through urine.

Diabetes is divided into type 1 and type 2. Type 1 diabetes, also called ‘juvenile diabetes,’ is a disease caused by the inability to produce insulin at all. Type 2 diabetes is a disease caused by a relative lack of insulin, and is characterized by insulin resistance (insulin's ability to lower blood sugar levels is reduced, and cells cannot burn glucose effectively). Type 2 diabetes can be caused by defects in specific genes in addition to environmental factors such as high-calorie, high-fat, and high-protein diets due to the westernization of eating habits, lack of exercise, and stress. In addition, type 2 diabetes can also be caused by pancreatic surgery, infection, or medications.

In the case of type 1 diabetes, insulin treatment is required, and in the case of type 2 diabetes, it is based on lifestyle modification and may require additional medication. In the case of type 1 diabetes or advanced type 2 diabetes in which endogenous insulin secretion is severely reduced, blood sugar fluctuations are severe, and multiple insulin injections that mimic physiological insulin secretion or the use of an insulin pump are essential, and continuous treatment is required to support this treatment. It is recommended to use blood sugar measurement.

Diabetic patients must receive systematic education on multiple insulin injections. In addition to the difficulty of education itself, there are also difficulties in administering the appropriate amount of insulin at the right time for various reasons.

Accordingly, the present invention proposes a method by which diabetic patients can manage their blood sugar using a continuous blood glucose meter and a device using the same.

A method of managing blood sugar by an electronic device using a continuous blood glucose meter according to the present invention includes the steps of receiving blood sugar data measured by the continuous blood glucose meter, determining the amount of insulin to be administered based on the measured blood sugar data, It includes the step of determining when to administer the determined insulin, and the amount of insulin to be administered may be an amount determined in consideration of the severity of diabetes.

In the method of managing blood sugar by an electronic device using a continuous blood sugar meter according to the present invention, the step of receiving the blood sugar data may be a step of periodically receiving measured blood sugar data from the continuous blood sugar meter or a server of the continuous blood sugar meter. there is.

In the method of managing blood sugar by an electronic device using a continuous blood glucose meter according to the present invention, the insulin to be administered is insulin administered by basal injection, and the amount of insulin to be administered is A blood sugar level 4 hours after dinner and A the next morning. When the blood sugar level is set to B at 8 a.m. before a meal, if the fluctuation range of blood sugar level during the night is within 20 mg/dL (|A-B|<=20) and the blood sugar level does not fall below 70 mg/dL the next morning (B>70) The amount of insulin administered as a basal injection may not be changed.

In the method in which the electronic device manages blood sugar using a continuous blood glucose meter according to the present invention, the insulin to be administered is insulin administered by basal injection, and the amount of insulin to be administered is such that blood sugar falls by more than 20 mg/dL during the night (A-B >20), the blood sugar range the next morning is not normal, or the blood sugar level 4 hours after a meal exceeds the low_cutoff standard according to the patient's severity (A > low_cutoff standard), and the blood sugar level rises by more than 20mg/dL during the night (A-B<- 20) In order to prevent consumption (rebound phenomenon), if the lowest blood sugar (L) is maintained above 80 between A and B (L > 80), the amount of insulin to be administered is (A-B)/Q * (24) /W), where Q is the initial correction coefficient of 1800 ÷ the total daily amount of insulin or the additional blood sugar drop when one additional unit of rapid-acting insulin is used, W is the time from 4 hours after dinner to 8 am before breakfast In addition, whether the range of blood sugar in the next morning is normal is determined based on the range of blood sugar in the normal range of 90-130 for general patients, 90-140 for patients in the moderate high-risk group, and 100-150 for patients in the severe high-risk group, and the low_cutoff standard value can be judged based on 125 for general patients, 135 for moderately high-risk group patients, and 145 for severe high-risk group patients.

In the method of managing blood sugar by an electronic device using a continuous blood glucose meter according to the present invention, the insulin to be administered is insulin administered by rapid-acting bolus injection, and the amount of insulin to be administered is A blood sugar level of 4 hours after dinner. , When the pre-meal blood sugar level is set to E, if the blood sugar level 4 hours after dinner is below 70 or the blood sugar level 4 hours after dinner increases by more than 30 mg/dL compared to the pre-meal blood sugar level (E-A<-30), The amount of insulin to be administered is (E-A)/Q, where Q is the initial correction coefficient and may be 1800 ÷ the total daily amount of insulin or the blood sugar level that additionally drops when one more unit of rapid-acting insulin is used.

The method in which the electronic device according to the present invention manages blood sugar using a continuous blood glucose meter is that if the blood sugar level is maintained constant after dinner and then surges by more than 20 mg/dL from after 3 a.m. to just before breakfast, the blood sugar level measured at 3 a.m. When blood sugar is C, if the blood sugar level at 8 a.m. before breakfast is 20 mg/dL greater than the blood sugar level measured at 3 a.m. (C-B<-20), a step of sounding an alarm or vibrating may be further included.

In the method of managing blood sugar using a continuous blood glucose meter by an electronic device according to the present invention, the step of determining when to administer the determined insulin is determined when the highest blood sugar level after a meal increases by more than 50 mg/dL compared to the blood sugar level before a meal in the measured blood sugar data. And, if the blood sugar levels both before and 4 hours after the meal are within normal levels, the injection time is advanced within the range of 30 minutes before the meal and 30 minutes after the meal (insulin usually taken just before or after the meal is administered 15 to 20 minutes after the meal). You can decide when to administer insulin by advancing the dose by minutes.

In the method of managing blood sugar using a continuous blood glucose meter by an electronic device according to the present invention, the step of determining the time to administer the determined insulin includes determining that the lowest blood sugar level between 4 hours before and after a meal is 70 mg/dL in the measured blood sugar data. Below, if the blood sugar levels both before and 4 hours after the meal are within normal levels, the injection time is delayed within the range of 30 minutes before the meal and 30 minutes after the meal (insulin usually taken before the meal is delayed to about 30 minutes immediately after the meal to about 30 minutes after the meal). ) can help you decide when to administer insulin.

A computer-readable recording medium for managing blood sugar using a continuous blood glucose meter according to the present invention may record a computer program for executing at least one of the methods described above.

An electronic device that manages blood sugar using a continuous blood glucose meter according to the present invention can execute at least one of the methods described above.

According to the present invention, diabetic patients can independently determine the amount and/or timing of insulin to be administered using a continuous blood glucose meter, thereby maximizing the use of multiple insulin injections or an insulin pump to control blood sugar close to normal while minimizing the risk of hypoglycemia. You can.

According to the present invention, it is possible to provide a blood sugar control guide customized to each diabetic patient by dataizing the factors that cause abnormal blood sugar levels in each diabetic patient.

According to the present invention, it is possible for diabetic patients who have only a basic level of knowledge about insulin treatment to manage insulin administration in an individually customized manner in terms of the amount and/or timing of insulin to be administered without additional advanced training. do.

According to the present invention, medical staff can monitor individual data of diabetic patients and fill in the gaps during treatment.

Figure 1 shows a system for managing blood sugar using a continuous blood glucose meter according to an embodiment of the present invention.

Referring to FIG. 1, a system for managing blood sugar using a continuous blood glucose meter may include a continuous blood glucose meter 100 and an electronic device 110. A system for managing blood sugar using a continuous blood glucose meter may further include a server 160.

The continuous blood glucose meter 100 may include a sensor and a transmitter. The sensor is a sensor that can measure glucose and is inserted under the skin to measure glucose in interstitial fluid. Glucose measurement using interstitial fluid may be delayed by 5 to 15 minutes compared to the actual blood sugar value. The continuous blood glucose meter 100 may measure the amount of glucose with a sensor periodically, for example, once every 5 minutes, and transmit the measured amount of glucose to the electronic device 110 using a transmitter. The continuous blood glucose meter 100 may further include a receiver and/or a display.

The electronic device 110 may include a communication module 120, a processor 130, and an input/output module 140. The electronic device 110 may further include a database 150.

The communication module 120 may receive the amount of glucose measured from the continuous blood glucose meter 100, and the processor 130 may determine the amount and/or timing of insulin to be administered based on the amount of glucose received. . The processor 130 may store at least a portion of the amount of glucose received and the amount and/or timing of the administered insulin in the database 150 or/and the server 160.

The input/output module 140 may be a module for a diabetic patient to input the type and amount of food before a meal. Here, the input/output module 140 is shown as one, but may be configured as a separate module. For example, an input module can be a mouse or/and a keyboard, and an output module can be a display such as a monitor or speakers.

The server 160 may store information necessary for the treatment of diabetic patients. For example, at least some of the blood sugar information transmitted from the diabetic patient's electronic device 110, the amount and/or timing of administered insulin, and information about the food consumed may be stored. The server 160 may store information on a plurality of diabetes patients.

Hereinafter, a detailed description will be given of how the electronic device 110 of FIG. 1 determines the amount and/or timing of administered insulin based on the amount of glucose (i.e., blood sugar) measured from the continuous blood glucose meter 100.

Diabetes patients can be divided into general patients, moderate high-risk patients, and severe high-risk patients depending on the severity. The severity of diabetes patients can be determined by a doctor's judgment and/or questionnaire. Depending on the severity of diabetes, the dosage and timing of insulin administration may vary.

Insulin injections can be divided into rapid-acting bolus injections and basal injections depending on the dose of insulin. Rapid-acting bolus injections act as mealtime insulin (or bolus insulin). In other words, a large amount of insulin is injected at once using a rapid-acting bolus injection to lower blood sugar levels that rise rapidly after a meal. Basal injections act as basal insulin (or basal insulin, long-acting insulin). In other words, a small amount of insulin is injected as a basal injection to control blood sugar levels while sleeping at night and before meals. The amount of insulin administered by rapid-acting bolus injection can be determined (or adjusted) based on the difference between the blood sugar level before a meal and the blood sugar level 4 hours after a meal in a diabetic patient, and the amount of insulin administered by basal injection is It can be determined (or adjusted) based on the difference between blood sugar levels 4 hours after a diabetic patient receives a rapid-acting bolus injection after dinner and blood sugar levels at 8 a.m. before breakfast the next morning.

The following explains in detail how to determine the amount of insulin to be administered to a diabetic patient. The presence or absence of a meal, meal start time, meal end time, etc. may be directly input by the user, that is, a diabetic patient, or may be set in advance.

Amount of insulin to be administered as a basal injection

Let's say the blood sugar level 4 hours after dinner is A, and the blood sugar level at 8 a.m. before breakfast the next day is B. The fluctuation range of blood sugar level during the night is within 20 mg/dL (|A-B|<=20), and the next morning blood sugar level is 70 mg. If it does not fall below /dL (B>70), the amount of insulin administered as a basal injection can be considered appropriate. Therefore, the amount of insulin administered by basal injection can be maintained as is.

If blood sugar levels drop by more than 20mg/dL during the night (A-B>20) and the blood sugar range is not normal the next morning, the amount of insulin administered as a basal injection may need to be reduced. The range of blood sugar that is considered normal may vary depending on the severity of the diabetes patient. [Table 1] below shows, as an example, the normal range of blood sugar according to the severity of diabetes patients.

Severity in Diabetes Patients blood sugar in the normal range general patient 80-130 Severe and high-risk patients 90-140 Severe high-risk patients 100-150

Or, blood sugar level 4 hours after a meal exceeds the low_cutoff standard according to the patient's severity (A > low_cutoff standard), blood sugar rises more than 20mg/dL during the night (A-B<-20), and prevention of consumption phenomenon (rebound phenomenon) If the lowest blood sugar level (L) between A and B is maintained above 80 (L > 80), the amount of insulin administered as a basal injection may need to be increased. [Table 2] below shows the low_cutoff standard value according to the severity of diabetes patients as an example.

Severity in Diabetes Patients low_cutoff threshold general patient 125 Severe and high-risk patients 135 Severe high-risk patients 145

The increase or decrease in the amount of insulin administered through the basic injection described above can be obtained as in [Equation 1].

[Equation 1]

Amount of insulin that needs to be increased or decreased by basal injection = (A-B)/Q * (24/W)

Here, Q is the initial correction coefficient, which can be 1800 ÷ the total amount of daily insulin or the additional blood sugar drop when one more unit of rapid-acting insulin is used, and W can be the time from 4 hours after dinner to 8 o'clock before breakfast. there is.

Amount of insulin to be administered by rapid-acting bolus injection

If the blood sugar level 4 hours after dinner is A and the pre-meal blood sugar level is E, if the blood sugar level 4 hours after dinner is below 70, the amount of insulin administered by rapid-acting bolus injection may need to be reduced. . This may be due to a diet that is too low in carbohydrates or low in fat/protein.

However, if the blood sugar level 4 hours after dinner increases by more than 30 mg/dL compared to the blood sugar level before the meal (E-A<-30), the amount of insulin administered by rapid-acting bolus injection may need to be increased. This may be due to a diet that is too high in carbohydrates or high in fat/protein.

The amount of insulin administered by rapid-acting bolus injection can be increased or decreased according to [Equation 2].

[Equation 2]

Amount of insulin increased or decreased by rapid-acting bolus injection = (E-A)/Q

Here, Q is the initial correction coefficient, which can be 1800 ÷ the total amount of daily insulin or the additional blood sugar drop when one more unit of rapid-acting insulin is used.

According to one embodiment, a diabetic patient eats the same food in the same amount, but if the number of carbohydrate grams equivalent to 0.5 units per insulin injection differs from the previous one, the carbohydrate count adjustment process can be performed again.

Additionally, since these adjustments to the carbohydrate coefficient and correction coefficient are affected by the time of day even for the same person, they are each performed according to a predetermined time zone.

Since the amount of insulin secreted in the body may vary from day to day, the average value is calculated based on the data for a certain period (e.g., 3 days) excluding special days such as days of exercise or overeating among the weekly data and administered to diabetic patients. It can guide you on whether to increase, decrease, or maintain the insulin you take.

According to an embodiment of the present invention, a response plan can be proposed when a specific change occurs in a diabetic patient through accumulated blood sugar data.

For example, if the blood sugar level remains constant after dinner and then surges by more than 20 mg/dL from after 3 a.m. to just before breakfast, let's say the blood sugar measured at 3 a.m. is C, and the blood sugar level at 8 a.m. before breakfast is If the blood sugar level measured at 3 a.m. is greater than 20 mg/dL (C-B<-20), an alarm or vibration can be set to sound so that a rapid-acting bolus injection can be administered to the diabetic patient.

As another example, if a diabetic patient eats a snack before bedtime without taking rapid-acting insulin, and if the blood sugar level rises more than 50 mg/dL 4 hours after dinner before going to bed, or if it rises more than 50 mg/dL until midnight or 1 a.m., the diabetic patient may be given a fast-acting insulin supplement. An alarm or vibration can be set to sound so that Hyosung bolus injection can be administered.

The following explains in detail how to determine when to administer insulin to a diabetic patient.

If the peak does not exceed 50 mg/dL compared to the pre-meal blood sugar level and differs by less than 22 mg/dL by 4 hours after a meal, the administration dose and timing can be judged appropriate. However, if the peak blood sugar level after a meal rises by more than 50 mg/dL compared to the blood sugar level before a meal, and the blood sugar levels both before and 4 hours after a meal are within normal levels, it can be decided to advance the timing of insulin administration, and between 4 hours before and 4 hours after a meal. If the lowest blood sugar level is less than 70 mg/dL and the blood sugar levels both before and 4 hours after a meal are within normal levels, it can be decided to postpone the administration of insulin. For example, you can decide to advance the insulin you take right before or after a meal to 15 to 20 minutes before a meal, or to delay the insulin you take before a meal to about 30 minutes after a meal. Specifically, each diabetic patient can decide to advance or delay the injection time based on the current preset injection time. The range determined for when to administer the insulin may be 30 minutes before a meal or 30 minutes after a meal. For example, even if it is decided to advance the insulin injection time, if the diabetic patient is already injecting 30 minutes before a meal, it may not be advanced any further. Even if it is decided to delay the insulin injection time, if the patient is already injecting 30 minutes after a meal, it may not be advanced any further. You can decide not to delay any longer.
