Technical Field

The utility model relates to the technical field of medical instruments, in particular to a glucometer for insulin dosage decision reminding.

Background

Diabetes Mellitus (DM) is a chronic disease characterized by hyperglycemia, and is caused by absolute or relative insufficiency of insulin secretion, and abnormal biological metabolism.

Interpretation of blood glucose results and adjustment of insulin dosage are skills possessed by professional staff such as physicians, pharmacists, and the like. The regulation of insulin dosage is currently mainly based on physician clinical experience, and there is no unified regulation standard. Although guidelines promulgated by the American diabetes Association, the diabetes society of Chinese medicine, and the like, unify the insulin regulation standards for diabetes, there is no good application to achieve insulin regulation homogenization. In addition, as more and more diabetic patients are in home, if insulin is inaccurately regulated in home care, the treatment effect is affected, even danger occurs, and the insulin dosage decision depends on the calculation and notification of medical staff, so that the problem of inconsistent and inconsistent decision exists.

In the prior art:

(1) the patent insulin pump (CN104667379A) with dynamic closed-loop control mainly focuses on the improvement of the insulin administration program, the driving mechanism is connected with the injection device of the insulin pump and transmits and controls the injection amount information, the driving mechanism needs to be connected with a mechanism for detecting the blood sugar information of a human body, and the patient cannot know the control information of the insulin-blood sugar value by the closed-loop control. And the blood sugar detection mechanism, the drug administration mechanism, the driving mechanism and the dynamic control module have high manufacturing cost, and cannot benefit the general audience of diabetes, and only aims at the diabetes patients using the insulin pump. An insulin pump injection device is different from a blood glucose meter, the blood glucose meter is an electronic instrument for measuring blood glucose level and is the most commonly used equipment, an insulin pump is an insulin treatment method which adopts an insulin input device controlled by artificial intelligence, and simulates the physiological secretion mode of insulin through the continuous subcutaneous insulin infusion mode so as to control hyperglycemia.

The technology cannot calculate the insulin dosage after the existing blood sugar level detection, is not suitable for a patient who uses a glucometer to measure and needs to inject the insulin dosage, is only suitable for a patient who enters a system in a hospital, needs medical staff to operate and prompt, and is inconvenient for providing decision prompt for the patient.

(3) A blood glucose meter (CN211453640U) with cloud analysis of data: the utility model discloses a blood glucose meter with data high in clouds analysis function, including shell, display screen, test paper interface, regulating switch, megaphone. The cloud server relies on the embedded sensor, can share blood sugar test data, improves user experience. The utility model aims to solve the problems of blood sugar value recording, analysis and early warning, and can transmit the data in real time to generate the own blood sugar value history when a patient needs to provide the data for a doctor to analyze and monitor. The biggest characteristic is that the blood sugar test function of the patient can be stored and recorded. However, the technology does not describe where the cloud server belongs, such as the cloud storage provided by the inventor or some APP, and how the data of the patient should be extracted after being stored. The technology describes a life cycle of continuous data, but does not carry out algorithm analysis and utilization on collected blood sugar data, actually provides convenience for patients, and provides references for insulin dosage for medical staff. And simultaneously, the requirement of self-nursing patients at home cannot be met.

As shown in fig. 1 to 2, the blood glucose meter for insulin dosage decision reminding of the present invention comprises a blood glucose detecting module 1, a memory 2, an insulin dosage decision module 3 and a display module 4, wherein an output end of the blood glucose detecting module is connected with an input end of the memory, an output end of the memory is connected with an input end of the insulin dosage decision module 3, and an output end of the insulin dosage decision module 3 is connected with the display module 4;

furthermore, the output end of the insulin dosage decision module 3 is also connected with an SDK interaction database 5, and the SDK interaction database 5 is connected with a client 6;

in the embodiment, the SDK interaction database 5 is connected to a manufacturer background database in order to implement long-term storage of user data, and is accessed to the database or the shared database through a connection code; the blood glucose monitoring module is used for detecting the current blood glucose concentration, inputting the blood glucose concentration into the memory for data storage, judging the insulin dosage through the insulin dosage decision module 3, finally displaying the insulin dosage through the display module 4, transmitting the insulin dosage to the SDK interactive database 5 through WiFi, and transmitting the SDK interactive database 5 to the WeChat applet of the client 6 through WiFi for watching;

the insulin dosage decision module adopts the following algorithm: based on the guidelines published by the Chinese diabetes society, the blood sugar control targets of Chinese diabetic patients are as follows: the blood sugar of the capillary blood vessel is 3.9-7.2mmol/L in fasting state, and is not more than 10mmol/L in non-fasting state; principle of algorithm program: morning Short Acting Insulin (SAIB) plays a major role between breakfast and lunch, with its glycemic control reflected in pre-lunch blood glucose levels; moreover, the morning Intermediate Acting Insulin (IAIB) plays a major role between lunch and dinner, with its glycemic control reflected in the blood glucose concentration before dinner; short-acting insulin at night (SAID) plays a major role between dinner and bedtime, with glycemic control reflected in blood glucose levels at bedtime; finally, the evening Intermediate Acting Insulin (IAID) plays a major role during the night, with its glycemic control reflected in the next morning blood glucose test results; in the algorithm, the unit of insulin dosage is U, and the unit of blood glucose level is mmol/L; selecting the type of insulin according to the safety range of the blood sugar of a diabetic patient specified by the diabetes society, inputting the total daily dose of the used insulin and the content of carbohydrates in diet, and automatically calculating the insulin dosage by a system;

specifically, a calculation formula is input in the applet terminal code, and the contents as shown in fig. 2 are displayed;

determining the Total daily amount

Body weight (kg unit) 0.7 (required amount per kg per day)

Type 1 diabetes mellitus: 0.5-1U/kg/d

Type 2 diabetes: 0.3-0.8U/kg/d

Note: generally starting from a minimum dose; but the heavier the weight, the heavier the insulin resistance, the more likely the CIR will be to be different at different meals in the day, starting from the median value, where the ratio of carbohydrate to insulin (CIR) is 1 unit of carbohydrate grams covered by insulin, the CIR is calculated by dividing the constant 450 by the Total Daily Dose (TDD);

CIR-＝450/TDD

for example:

TDD 50 units insulin

CIR 450/50 g/unit

The meal contains 90 g of carbohydrate

Prandial insulin dose-carbohydrate/carbohydrate to insulin ratio CIR 90/9-10 units

If postprandial blood glucose exceeds the target blood glucose range for 2 to 3 days, please consider to reduce the CIR by 10% to 20%

If postprandial blood glucose is below the target blood glucose range within 2 to 3 days, the CIR is considered to be increased by 10% to 20%

Calculation of correction dose:

if the pre-meal blood glucose is outside the target range, the insulin dosage associated with the meal may need to be adjusted accordingly. In order to restore the blood glucose from the current blood glucose to the desired pre-prandial blood glucose, it is necessary to determine the amount of blood glucose that is reduced by injecting 1 unit of insulin. The amount of blood glucose reduced by the injection of 1 unit of insulin is called the insulin sensitivity factor (also called the correction factor) and is calculated by dividing the total daily dose of rapid acting insulin (TDD) by the constant 1700, or by dividing the total daily insulin dose of short acting insulin (TDD) by the constant 1500.

Insulin sensitivity factor (correction factor) 1700/TDD

Patients used rapid acting insulin.

TDD 50 units insulin

ISF＝1700/50＝34mg/dL

The blood sugar before meal is 160mg/dL

The target pre-meal blood glucose is 90mg/dL

Conversion of mg/dL and mmol/L: conversion from mmol/L to mg/dL requires multiplication by 18, whereas conversion from mg/dL to mmol/L requires division by 18

Corrected dose (current blood glucose-target blood glucose)/ISF (160-90)/34-2.1 units

According to the calculation formula, terminal program codes are input and executed through conditional statements.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
