20220375615
This application is based on and claims priority under 35 U.S.C. 119 to Korean Patent Application No. 10-2021-0063884, filed on May 18, 2021, in the Korean intellectual property office, the disclosures of which are herein incorporated by reference in their entireties.
The following description relates to a method and system for predicting a health risk.
Examples in which adult-onset diseases, such as diabetes, hyperlipidemia and thrombosis, are increased continue to increase. Such diseases need to be periodically measured using various bio sensors because it is important to continuously monitor and manage the diseases. A common type of bio sensor is a method of injecting, into a test strip, blood drawn from a finger and then quantizing an output signal by using an electrochemical method or a photometry method.
However, about half of diabetes patients have experienced hypoglycemia for the last six months. It was found that 1/3 of the half of the diabetes patients has repeatedly experienced hypoglycemia three times or more. If a diabetic patient does not take sugar within a short time when a hypoglycemia symptom appears, the diabetic patient may go into a hypoglycemia shock, and may lose his or her consciousness or lead to death in severe cases. For this reason, diabetes patients suffer from a fear of a hypoglycemia shock and feel inconvenient to frequently check blood glucose.

The display may display at least one of an HCI, an HCI prediction value and a danger alert signal.
The communication unit may transmit at least one of an HCI, an HCI prediction value and a danger alert signal to another device (e.g., the display device 320, the cloud server 330 and at least one of the plurality of family devices 341 to 343).

In this case, the data receiver 810 may receive an HCI transmitted by the monitoring device 850 through the data transmitter 853. In this case, the time-series data generator 820, the HCI prediction unit 830 and the alert signal generator 840 may correspond to the time-series data generator 730, the HCI prediction unit 740 and the alert signal generator 750 described with reference to
In other words, the time-series data generator 820 may generate time-series data by using an HCI received by the data receiver 810. The HCI prediction unit 830 may calculate an HCI prediction value in a future time by inputting the time-series data to the HCI prediction model 831. Furthermore, the alert signal generator 840 may compare the HCI prediction value, calculated by the HCI prediction unit 830, with a preset threshold setting value 841, and may generate a danger alert signal when the HCI prediction value is out of the threshold setting value 841.
In this case, the display device 800 may further include an alert signal output unit (not illustrated), a display (not illustrated) and a communication unit (not illustrated). The alert signal output unit may output a danger alert signal generated by the alert signal generator 840.

In step 920, the computer device 200 may generate time-series data. As described above, the computer device 200 may generate time-series data by accumulating an HCI at given time intervals in the form of a two-dimensional array. If HCIs include a plurality of types, the computer device 200 may generate time-series data by accumulating the HCIs at given time intervals for each type.
In step 930, the computer device 200 may calculate an HCI prediction value in a future time by inputting the time-series data to an HCI prediction model. As described above, the HCI prediction model may be generated to learn an AI algorithm model through machine learning using learning data, receive time-series data and output an HCI prediction value in one or more future times.
In step 940, the computer device 200 may compare the calculated HCI prediction value with a preset threshold. In this case, when the calculated HCI prediction value is out of the preset threshold, step 950 may be performed. As described above, the threshold may include a case where an upper threshold, a case where a lower threshold is present, and a case where both a lower threshold and an upper threshold are present depending on the type of HCI. In some embodiments, the threshold may be present in the form of a range between a first threshold and a second threshold. In this case, when an HCI prediction value is a value between the first threshold and the second threshold, the HCI prediction value may be determined to be out of the threshold.
In step 950, the computer device 200 may generate a danger alert signal. For example, if the calculated HCI prediction value is determined to be out of the preset threshold in step 940, in step 950, the computer device 200 may generate a danger alert signal. If the calculated HCI prediction value is determined to be not out of the preset threshold, step 910 may be repeatedly performed or the process may be terminated.
Furthermore, in some embodiments, the system 300 for predicting a health risk may generate a guide for improving a lifestyle for the purpose of continuous health management and provide a user with the guide, in addition to previously predicting and providing notification of a health risk.
For example, referring back to
