The memory 12, 102, or 202 is a computer-readable recording medium, and may include random access memory (RAM), read only memory (ROM), and a permanent mass storage device such as a disk drive.

The processor 13, 103, or 203 may be configured to process commands of a computer program by performing basic arithmetic operations, logic operations, and I/O operations. A command may be provided to the processors 13, 103, and 203 by the memories 12, 102, and 202 or the communication modules 14, 104, and 204. For example, processors 13, 103, and 203 may be configured to execute commands that are received according to a program code stored in a recording device such as the memories 12, 102, and 202. In an embodiment, the processor 103 of the insulin patch control device 100 obtains blood sugar information from the insulin patch 10, inputs the blood sugar information obtained as above into a first neural network, estimates the pump parameter of the insulin patch based on output data from the first neural network, transmits a control signal to the insulin patch based on the estimated pump parameter, obtains control result data from the insulin patch 10, inputs the blood sugar information, the pump parameter, and the control result data to a second neural network, and may estimate the pathology diagnosis result data of the user of the insulin patch based on output data from the second neural network.
The communication modules 14, 104, and 204 may provide communicating function via the network. For example, a request generated by the processor 103 of the insulin patch control device 100 according to program code stored in a storage device such as the memory 102 may be transferred to the insulin patch 10 via the network according to control of the communication module 104. In addition, control signals, commands, content, files, etc. provided under the control of the processor 203 of the medical service providing server 200 may be transferred to the insulin patch control device 100 through the communication module 104 over a network. Moreover, the control signal or command of the medical service providing server 200 received through the communication module 104 of the insulin patch control device 100 may be transferred to the processor 103 or the memory 102 of the insulin patch control device 100, and blood sugar information and/or control result data from the insulin patch 10 may be stored in a storage medium that may be further included in the insulin patch control device 100.

In operation S110, an insulin patch control device may obtain blood sugar information from a blood sugar sensor of an insulin patch. In an embodiment, the insulin patch may obtain blood sugar information of the user via the blood sugar sensor. The kind of the blood sugar sensor according to some embodiments of the present invention is not restricted, for example, the blood sugar sensor may be a continuous glucose monitoring (CGM) sensor. In an embodiment, the blood sugar information may include a blood sugar level of the user, and in some embodiments, may further include information regarding the blood sugar measurement time and method.
In operation S120, the insulin patch control device may input the obtained blood sugar information to a first neural network and may estimate a pump parameter of the insulin patch based on output data from the first neural network. In an embodiment, the first neural network receiving the input of the blood sugar information may estimate an insulin injection amount according to the blood sugar level included in the blood sugar information. In this case, the amount of insulin injected through the insulin patch may be adjusted according to the pump parameter. Therefore, according to an embodiment, the above first neural network receiving blood sugar information may estimate an optimal pump parameter based on blood sugar information obtained in real-time.
In another embodiment, the insulin patch may estimate the pump parameter independently from the insulin patch control device based on measured blood sugar information, and adjust the insulin injection amount based on the estimated pump parameter. That is, the insulin patch control method according to the present embodiment may stably inject insulin to the user even when there is a communication issue between the insulin patch and the insulin patch control device or when an issue occurs in the insulin patch control device. More detailed description will be provided later with reference to
In operation S130, the insulin patch control device may transmit a control signal to the insulin patch based on the pump parameter estimated in operation S120. In an embodiment, the insulin patch control device and the insulin patch may communicate with each other via a network. As described above, the communication method of the network between the insulin patch control device and the insulin patch is not limited, but in an example, the above network may be a near field wireless communication network, for example, a Bluetooth communication network.
In another embodiment, the insulin patch control device may perform a simulation based on an insulin injection algorithm using the estimated pump parameter before transmitting a control signal to the insulin patch. In addition, the insulin patch control device may re-estimate the pump parameter based on the simulation result. For example, when an expected blood sugar level of the user exceeds an effective range as a result of simulation, the estimated pump parameter may be determined not to be effective, and after that, the pump parameter may be re-estimated by using the above neural network. The accuracy of the insulin patch may be improved through the insulin patch control method according to the present embodiment. This will be described in more detail later with reference to
In operation S140, the insulin patch control device may obtain control result data from the insulin patch. In an embodiment, the control result data of the insulin patch may include at least one of blood sugar information measured over time, a pump parameter estimated according to the measured blood sugar information, an injection amount of insulin that is injected according to the pump parameter, and blood sugar information after insulin injection. The kind and form of the data included in the control result data of the insulin patch according to some embodiments of the present disclosure are not restricted. For example, the control result data of the insulin patch may be one of time-serial data related to the blood sugar level, time-serial data related to the pump parameter, and time-serial data related to the insulin injection amount, may include data in the form of a pair of the insulin injection amount and the blood sugar level, or may include data in the form of a pair of the pump parameter and the blood sugar level.
In operation S150, the insulin patch control device may input the blood sugar information, the pump parameter, and the control result data of the insulin patch into the second neural network, and in operation S160, the insulin patch control device may estimate pathology diagnosis result data of the user of the insulin patch based on output data from the second neural network. In more detail, the insulin patch control device according to an embodiment may obtain first pathology diagnosis result data by inputting the blood sugar information and the pump parameter into the second neural network, and after that, may perform a feedback with respect to the above first pathology diagnosis result data based on the control result data of the insulin patch. For example, the above second neural network may be re-trained by using the first pathology diagnosis result data and the control result data of the insulin patch. For example, the insulin patch control device may perform reinforcement training of the second neural network by using the control result data of the insulin patch. In this case, the control result data of the insulin patch may include a control signal of the insulin patch based on the pump parameter and blood sugar information according to insulin injection, and may further include information on a diabetes diagnosis result of the user in some embodiments.
In another embodiment, above operations S150 to S160 may be performed by an external server that is connected to the insulin patch control device via the network. In the present embodiment, the external server may include a hospital server or a medical service providing server. In this case, the external server may receive an input of a user feedback signal with respect to the pump parameter of the insulin patch, the simulation result of the insulin patch, or pathology diagnosis result data of the user. In this case, the user may be a user of the hospital server and the medical service providing server, for example, a doctor, a nurse, or a medical staff. After that, the feedback signal of the external server according to some embodiments of the present disclosure may be re-input into the first neural network or the second neural network so as to re-train the neural network.
Hereinafter, a series of processes for controlling an insulin patch according to an embodiment of the present disclosure will be described in detail with reference to
The insulin patch 10 according to an embodiment of the present disclosure may perform network communication with a user terminal 20 capable of monitoring and/or controlling the insulin patch. In an example, the insulin patch 10 and the user terminal 20 may communicate through Bluetooth communication. The user terminal 20 according to the present embodiment may have an application for monitoring and/or controlling the insulin patch 10 installed thereon, and the user terminal 20 may receive a user input with respect to the insulin patch in real-time via the application. In this case, according to an embodiment, the insulin patch 10 may independently estimate the pump parameter, only when the communication with the user terminal 20, as well as the insulin patch control device 100, is disconnected.
The insulin patch control device 100 according to an embodiment may estimate a pump parameter based on user information of the insulin patch. That is, the insulin patch control device 100 may simultaneously estimate the pump parameters of one or more insulin patches 10 and may estimate the pump parameter of each insulin patch 10 by further using the user information of each insulin patch 10. As such, personalized control of the insulin patch may be possible. Also, the insulin patch control device 100 may create a virtual insulin patch corresponding to each insulin patch and may perform a simulation of the insulin patch by using the estimated pump parameter. Because securing stability of insulin injection is very important, the insulin patch control device 100 according to some embodiments may stably control the insulin patch through the above processes.
According to an embodiment, the external device 200 that obtains the pathology diagnosis result data of the insulin patch user from the insulin patch control device 100 may further include an additional user terminal 210 that may receive a feedback signal with respect to the pathology diagnosis result data. In this case, a user inputting a feedback signal for the pathology diagnosis result data may be a medical staff such as a doctor. As such, the accuracy of the neural network for estimating the pump parameter performed by the insulin patch control device 100 or the external device 200 may be improved.
Hereinafter, each process performed by an insulin patch unit 300, the insulin patch control device 100, and a pathology diagnosis result data analysis unit 400 shown in
Hereinafter, a process of independently estimating a pump parameter, performed by an insulin patch, according to an embodiment of the present disclosure will be described in detail with reference to
In operation S210, blood sugar information may be obtained through a CGM sensor. However, the CGM sensor is just an example of the blood sugar measurement sensor, and according to some embodiments of the present disclosure, the blood sugar measurement sensor and blood sugar measurement method of the insulin patch are not necessarily restricted to the CGM sensor.
In operation S220, the pump parameter may be obtained through an algorithm designated based on the blood sugar information. In an embodiment, the designated algorithm may be similar to or same as the above-described first neural network, but when the subject of performing operation S220 is the insulin patch, the algorithm may be simplified algorithm having less calculation amount than the first neural network. For example, when an error of a user terminal communicating with an insulin patch, an error of an insulin patch control device, or a communication failure in a network occurs, the insulin patch according to the present embodiment may independently estimate the pump parameter. Accordingly, when the insulin patch according to an embodiment does not receive an insulin patch control signal or pump parameter information from the outside during a specified period of time, the insulin patch may independently estimate the pump parameter for determining the insulin injection amount. That is, the insulin patch according to the present embodiment may independently determine the insulin injection amount without communicating with an external device.
In operation S230, verification of effectiveness of the pump parameter may be performed. That is, before controlling the insulin patch using the obtained pump parameter, a minimum verification of effectiveness for securing stability may be performed. For example, it may be identified whether the obtained pump parameter is within a designated stable range. In this case, the designated stable range may be a fixed value input by the user, a value determined based on previous pump parameter records, or a value estimated through a designated algorithm as in operation S220. In an embodiment, the insulin patch may perform the verification of the effectiveness of the pump parameter, of course, when receiving the control signal of the insulin patch or the pump parameter from the insulin patch control device. That is, in the insulin patch control method according to the present embodiment, the effectiveness of the pump parameter may be verified by the insulin patch that includes the insulin injection portion, not by the insulin patch control device, in order to improve the stability.
In operation S240, the insulin patch may be controlled based on the pump parameter of which the effectiveness has been verified, the CGM sensor and the insulin patch control device may be controlled based on the control result, and the insulin patch control result data may be transmitted to the insulin patch control device. In another embodiment, when the effectiveness of the pump parameter is not verified in operation S230, the above-described operations S210 to S230 may be repeatedly performed.
Hereinafter, a process of performing simulation, performed by the insulin patch control device according to an embodiment of the present disclosure, will be described in detail with reference to
In operation S310, the insulin patch control device may perform verification of effectiveness of the obtained blood sugar information. The insulin patch control device may perform verification of the effectiveness of the blood sugar information, before inputting the blood sugar information obtained from the insulin patch into the neural network. For example, it may be identified whether the obtained blood sugar information is within an effective range. As such, the insulin patch control device may identify whether there is an error occurring in the insulin patch. The effective range of the blood sugar information may be a fixed value input by the user, a value determined based on past blood sugar information records of each user, or a value estimated through a certain algorithm.
In operation S320, the insulin patch control device may input the blood sugar information to the first neural network in order to estimate the pump parameter of the insulin patch. In an embodiment, the first neural network may be a neural network trained using user's blood sugar information before injecting insulin, an insulin injection amount, an insulin pump parameter, and user's blood sugar information after injecting insulin, or may be a neural network that is transfer-trained using another neural network that is trained by using the insulin injection amount and the blood sugar information. Also, in an embodiment, the first neural network may be a neural network trained by further using user information. As such, the insulin patch control device may estimate the pump parameter by further considering a degree of blood sugar change and speed for each user.
In operation S330, the insulin patch control device may classify the output data from the first neural network and select a pump parameter according to a designated condition from among pump parameters included in the output data. In an embodiment, the designated conditions for selecting a pump parameter may be determined based on user information. For example, the insulin patch control device may select an appropriate pump parameter between a pump parameter for injecting a small amount of insulin for a long period of time and a pump parameter for injecting a large amount of insulin for a short period of time, based on the user information.
In operation S340, the insulin patch control device may set the pump parameter of the insulin patch to be the pump parameter selected in operation S330, and may perform a simulation on a vertical insulin patch through an insulin injection algorithm based on the pump parameter set in operation S350.
In an embodiment, when the expected blood sugar level of the user exceeds the effective range as a result of the simulation, the insulin patch control device may determine that the estimated pump parameter is not effective. In this case, the insulin patch control device may perform a simulation of the insulin patch by using the pump parameter that is not selected in operation S330, and may perform a simulation by using the pump parameter that is re-estimated by repeatedly performing operations S310 to S340. Accuracy and stability of the estimated pump parameters may be improved by the insulin patch control method according to the present embodiment.
Hereinafter, a process of obtaining pathology diagnosis result data according to an embodiment of the present disclosure will be described in detail below with reference to
In operation S410, the insulin patch control device may input the obtained blood sugar information and the estimated pump parameter to the second neural network.
After that, in operation S420, the insulin patch control device may re-train the second neural network by using the output data from the second neural network and previously obtained control result data of the insulin patch. In an embodiment, the control result data of the insulin patch may include at least one of blood sugar information measured over time, a pump parameter estimated according to the measured blood sugar information, an injection amount of insulin that is injected according to the pump parameter, and blood sugar information after insulin injection.
In more detail, the insulin patch control device according to an embodiment may obtain first pathology diagnosis result data by inputting the blood sugar information and the pump parameter into the second neural network, and after that, may perform a feedback with respect to the above first pathology diagnosis result data based on the control result data of the insulin patch. For example, the above second neural network may be re-trained by using the first pathology diagnosis result data and the control result data of the insulin patch.
For example, the insulin patch control device may perform reinforcement training of the second neural network by using the control result data of the insulin patch. In this case, the control result data of the insulin patch may include a control signal of the insulin patch based on the pump parameter and blood sugar information according to insulin injection, and may further include information on a diabetes diagnosis result of the user in some embodiments.
