Description

Technical Field

[0001] The present invention mainly relates to the field of medical devices, and in particular to a blood glucose management system. Background Art

[0002] In a healthy individual, the pancreas automatically secretes insulin and glucagon based on blood sugar levels, maintaining a healthy blood sugar range. However, in diabetics, pancreatic function is abnormal, preventing the body from producing the necessary insulin. Diabetes is a metabolic disease, a lifelong condition. Current medical technology cannot cure diabetes; instead, it can control the onset and progression of diabetes and its complications by stabilizing blood sugar levels.

[0003] Diabetic patients need to test their blood sugar before injecting insulin. Currently, most testing methods use in-vivo blood sugar testing devices to continuously monitor blood sugar. These devices use disposable transcutaneous sensors inserted into the skin to measure the blood sugar concentration in the interstitial fluid. The transmitter then wirelessly transmits the blood sugar data to an external device in real time for the patient to view. This testing method is called continuous glucose monitoring (CGM). The external device then wirelessly transmits the required insulin infusion amount to the insulin pump and controls the insulin pump to deliver insulin subcutaneously, thus forming a blood sugar management system.

[0004] In the existing blood glucose management system, before establishing a wireless communication connection between an external device (referred to as a program module in this solution) and a blood glucose monitoring device (referred to as a detection module in this solution) and / or an insulin pump (referred to as an infusion module in this solution), which are functional devices on the body, the patient often needs to input the device identification code of the blood glucose monitoring device and / or the insulin pump so that the external device can recognize the broadcast signal of the blood glucose monitoring device and / or the insulin pump. The operation of inputting the device identification code is cumbersome and inconvenient for the patient.

[0005] Therefore, the prior art urgently needs a blood glucose management system that can avoid the need to input a device identification code and facilitate patients to operate and establish a communication connection. Summary of the Invention

[0006] An embodiment of the present invention discloses a blood glucose management system. When a patient operates to establish a communication connection, at least one device among the detection module, the infusion module and the program module acts as a signal source device to send a low-power broadcast signal, and at least one device acts as a device to be paired to establish a communication connection. The patient operates the device to be paired to establish a communication connection to approach the signal source device. When the device to be paired to establish a communication connection enters the effective range of the broadcast signal, it can search for the broadcast signal and pair with the signal source device to establish a communication connection. Since the effective range of the broadcast signal is small, this range is generally smaller than the normal distance between the two devices. This can avoid the device to be paired to establish a communication connection from searching for the wrong broadcast signal and establishing an erroneous communication connection. When the device to be paired to establish a communication connection searches for the broadcast signal, it can consider that the signal source device is the patient's own device. The patient does not need to enter a device code, and the device to be paired to establish a communication connection and the signal source device can automatically establish a communication connection, saving time and effort and improving the patient's user experience.

[0007] The present invention discloses a blood glucose management system, comprising at least one detection module for being attached to the skin surface to continuously detect the patient's current blood glucose value; at least one infusion module for infusing currently required medicines into the patient's body; and at least one program module for controlling the operation of the detection module and the infusion module, generating a medicine infusion instruction based at least on the current blood glucose value detected by the detection module, and controlling the infusion module to infuse medicines; the detection module, the infusion module and the program module can be paired to establish a communication connection to exchange data; wherein, when operating the pairing to establish a communication connection, at least one device among the detection module, the infusion module and the program module acts as a signal source device to send a low-power broadcast signal, and at least one device acts as a device to be paired to establish a communication connection to approach the signal source device. When the device to be paired to establish a communication connection enters the effective range of the broadcast signal of the signal source device, it can search for the broadcast signal and pair with the signal source device to establish a communication connection.

[0008] According to one aspect of the present invention, the effective range of the broadcast signal is 0 to 0.5 m.

[0009] According to one aspect of the present invention, the broadcast signal is a Bluetooth signal.

[0010] According to one aspect of the present invention, the device to be paired and establish a communication connection approaches the signal source device and enters the effective range of the broadcast signal, and pairs with the signal source device to establish a communication connection.

[0011] According to one aspect of the present invention, when there are at least two signal source devices and the effective ranges of the broadcast signals of at least two signal sources do not overlap, the devices to be paired to establish a communication connection approach the signal source devices in turn to enter the effective range of the broadcast signal, and pair with the signal source devices to establish a communication connection respectively.

[0012] According to one aspect of the present invention, when there are at least two signal source devices and the effective ranges of broadcast signals of at least two signal source devices partially overlap, in the overlapping area of ​​the effective ranges of the broadcast signals, the device to be paired to establish a communication connection is paired with the at least two signal source devices at the same time to establish a communication connection.

[0013] According to one aspect of the present invention, signal source devices of the same type are not paired to establish a communication connection.

[0014] According to one aspect of the present invention, when the detection module, the infusion module or the program module serves as a signal source device, the encoding formats of the broadcast signals sent by each module are different.

[0015] According to one aspect of the present invention, the signal source device does not search for and receive broadcast signals.

[0016] According to one aspect of the present invention, while transmitting the broadcast signal, the signal source device is also used to search for broadcast signals transmitted by other signal source devices, and the signal source devices can be paired to establish a communication connection.

[0017] According to one aspect of the present invention, after the signal source device pairs with the device to be paired to establish a communication connection and establishes a communication connection, the signal source sends a communication signal, and the transmission power of the communication signal is not less than the transmission power of the broadcast signal.

[0018] According to one aspect of the present invention, the effective range of the communication signal is 0 to 10 m.

[0019] According to one aspect of the present invention, the communication signal is a Bluetooth signal.

[0020] According to one aspect of the present invention, the signal source device is at least one infusion module, and the device to be paired and establish a communication connection is at least one detection module.

[0021] According to one aspect of the present invention, the signal source device is at least one detection module, and the device to be paired and establish a communication connection is at least one infusion module.

[0022] According to one aspect of the present invention, before the signal source device is paired with the device to be paired to establish a communication connection and establish a wireless communication connection, confirmation by the patient is required.

[0023] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0024] In the blood glucose management system disclosed in the present invention, when the patient operates to establish a communication connection, at least one device among the detection module, infusion module and program module acts as a signal source device to send a low-power broadcast signal, and at least one device acts as a device to be paired to establish a communication connection. The patient operates the device to be paired to establish a communication connection to approach the signal source device. When the device to be paired to establish a communication connection enters the effective range of the broadcast signal, it can search for the broadcast signal and pair with the signal source device to establish a communication connection. Since the effective range of the broadcast signal is small, this range is generally smaller than the normal distance between the two devices, which can avoid the device to be paired to establish a communication connection from searching for the wrong broadcast signal and establishing a wrong communication connection. When the device to be paired to establish a communication connection searches for the broadcast signal, it can consider that the signal source device is the patient's own device. The patient does not need to enter the device code, and the device to be paired to establish a communication connection and the signal source device can automatically establish a communication connection, saving time and effort and improving the patient's user experience.

[0025] Furthermore, the detection module, infusion module and program module can all serve as signal source devices and devices to be paired to establish communication connections. Different devices can be paired to establish communication connections with each other. The communication method is flexible, convenient for patients to operate, and improves the patient's usage experience.

[0026] Furthermore, the effective range of the broadcast signal is 0 to 0.5 m, which is generally smaller than the normal distance between patients. When the patient is operating to establish a communication connection, the distance between the patient's signal source device and the device to be paired to establish a communication connection and other patient devices is greater than the effective range of the broadcast signal. When the device to be paired to establish a communication connection searches for the broadcast signal, it can be considered that the distance between the device to be paired to establish a communication connection and the signal source device is close enough, and the signal source device is the device that the patient expects to pair to establish a communication connection, rather than the signal source device of other patients, to avoid establishing an erroneous communication connection.

[0027] Furthermore, there may be multiple signal source devices in the blood glucose management system. When the broadcast signals of multiple signal source devices do not overlap, the devices to be paired to establish a communication connection can approach the signal source devices in turn and pair to establish a communication connection one after another. When the broadcast signals of multiple signal source devices overlap, in the overlapping area of ​​the broadcast signals, the device to be paired to establish a communication connection can simultaneously pair with multiple signal source devices to establish a communication connection, which is convenient for patients to operate.

[0028] Furthermore, when a signal source device has insufficient communication channels, signal source devices cannot be paired to establish a communication connection, to avoid occupying communication channels and affecting the communication connection between the signal source device and the device to be paired. When signal source devices have sufficient communication channels, signal source devices of the same type can be paired to establish a communication connection, thereby increasing the redundancy of the blood glucose management system's communication links and enhancing the robustness of the communication system.

[0029] Furthermore, multiple signal source devices may be the same type of device, such as two detection modules serving as signal source devices. Different types of signal source devices may send broadcast signal encoding formats that are different. While sending broadcast signals, the signal source device may also search for and receive broadcast signals from other signal sources. When the encoding format of the searched broadcast signal is the same as its own type, it may refuse to pair with the signal source device that sent the broadcast signal to establish a communication connection, so as to avoid occupying the communication channel and affecting the communication connection between the signal source device and the device to be paired to establish a communication connection.

[0030] Furthermore, the signal source device does not have the function of searching and receiving broadcast signals, and the signal source devices will not be paired to establish a communication connection to avoid occupying the communication channel of the signal source device and affecting the communication connection between the signal source device and the device to be paired to establish a communication connection.

[0031] Furthermore, after the signal source device is paired with the device to establish a communication connection and establishes a communication connection, the signal source device increases the transmission power of the communication signal to increase the effective range of the communication signal, thereby facilitating the patient or guardian to remotely use the program module and control the blood glucose management system. If the patient does not need to use the program module remotely, the signal source device may not increase the transmission power of the communication signal after pairing with the device to establish a communication connection and establish a communication connection, thereby reducing power consumption of the signal source device.

[0039] As mentioned above, in the prior art, before an external device (referred to as a program module in this solution) establishes a wireless communication connection with a blood glucose detection device (referred to as a detection module in this solution) and / or an insulin pump (referred to as an infusion module in this solution), which are functional devices on the body, the patient often needs to input the device identification code of the blood glucose detection device and / or the insulin pump so that the external device can recognize the broadcast signal of the blood glucose detection device and / or the insulin pump. The operation of inputting the device identification code is cumbersome and inconvenient for the patient.

[0040] In order to solve this problem, the present invention provides a blood glucose management system. When the patient operates to establish a communication connection, at least one device among the detection module, infusion module and program module acts as a signal source device to send a low-power broadcast signal, and at least one device acts as a device to be paired to establish a communication connection. The patient operates the device to be paired to establish a communication connection to approach the signal source device. When the device to be paired to establish a communication connection enters the effective range of the broadcast signal, it can search for the broadcast signal and pair with the signal source device to establish a communication connection. Since the effective range of the broadcast signal is small, this range is generally smaller than the normal distance between the two devices. This can avoid the device to be paired to establish a communication connection from searching for the wrong broadcast signal and establishing a wrong communication connection. When the device to be paired to establish a communication connection searches for the broadcast signal, it can consider that the signal source device is the patient's own device. The patient does not need to enter the device code, and the device to be paired to establish a communication connection and the signal source device can automatically establish a communication connection, saving time and effort and improving the patient's user experience.

[0043] The following description of exemplary embodiments is merely illustrative and is not intended to limit the present invention, its application, or use in any sense. Technologies, methods, and apparatus known to those skilled in the art may not be discussed in detail herein, but to the extent applicable, such technologies, methods, and apparatuses should be considered part of this specification.

[0044] It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined or described in one figure, it will not need to be further discussed in the subsequent figure descriptions.

[0045] Figure 1 This is a schematic diagram of the relationship between modules of a general blood glucose management system.

[0046] The blood glucose management system disclosed in the embodiment of the present invention mainly includes a detection module 100 , a program module 101 and an infusion module 102 .

[0047] The detection module 100 is used to continuously monitor the patient's current blood glucose level. Typically, the detection module 100 is a continuous glucose monitoring (CGM), which can detect the patient's current blood glucose level in real time, monitor blood glucose changes, and transmit the current blood glucose information to the program module 101. The CGM includes an implantable sensor connected to a transmitter, which also includes a memory, a processor, a communication interface, etc. The transmitter is used to transmit at least the blood glucose data detected by the CGM and the CGM identifier information.

[0048] Infusion module 102 includes the necessary mechanical structures and electronic control units for infusing blood sugar-regulating drugs such as insulin and glucagon, including a drug reservoir, a drive mechanism, an infusion line and needle, a power supply, and a circuit board. These components are controlled by program module 101. Typically, infusion module 102 is an insulin pump, and the electronic control unit includes a transmitter, memory, a processor, and a communication interface. Based on the current insulin infusion volume data transmitted by program module 101, infusion module 102 infuses the patient's current insulin requirement. Simultaneously, the infusion status of infusion module 102 is also fed back to program module 101 in real time.

[0049] Program module 101 is used to control the operation of detection module 100 and infusion module 102. Based on at least the blood glucose level detected by detection module 100, program module 101 generates insulin infusion instructions and controls infusion module 102 to perform infusion. The program module 101 includes memory, a processor, a communication interface, a display, a patient interface, and other components. The memory stores programming instructions, and the processor executes the programming instructions in the memory. Program module 101 is connected to detection module 100 and infusion module 102, respectively. This connection can include conventional electrical or wireless connections.

[0050] The embodiments of the present invention do not limit the specific positions and connection relationships of the detection module 100, the program module 101 and the infusion module 102, as long as the aforementioned functional conditions are met.

[0051] In one embodiment of the present invention, the three modules are electrically connected to form a single integrated structure. Therefore, they can be applied to the same location on the patient's skin. By connecting the three modules into a single unit and applying them to the same location, the number of devices applied to the patient's skin is reduced, thereby minimizing interference with patient activity caused by multiple devices. Furthermore, this effectively resolves the issue of wireless communication reliability between separate devices, further enhancing the patient experience.

[0052] In another embodiment of the present invention, the program module 101 and the infusion module 102 are interconnected to form an integrated structure, while the detection module 100 is separately provided in another structure. In this case, the detection module 100 and the program module 101 transmit wireless signals to each other to achieve mutual connection. Thus, the program module 101 and the infusion module 102 are attached to a certain location on the patient's skin, while the detection module 100 is attached to another location on the patient's skin.

[0053] In another embodiment of the present invention, program module 101 and detection module 100 are interconnected to form a single device, while infusion module 102 is located in a separate structure. Infusion module 102 and program module 101 communicate with each other via wireless signals. Thus, program module 101 and detection module 100 can be attached to one location on a patient's skin, while infusion module 102 can be attached to another location on the patient's skin.

[0054] In another embodiment of the present invention, the three modules are disposed in different structures. Thus, the three modules are attached to different locations on the patient's skin. In this case, the program module 101 communicates wirelessly with the detection module 100 and the infusion module 102 to establish connections.

[0055] In another embodiment of the present invention, the three are arranged in different structures. Therefore, the detection module 100 and the infusion module 102 are respectively attached to different locations on the patient's skin, while the program module 101 does not need to be attached to the skin. The detection module 100 and the infusion module 102 are controlled by a handheld or portable device, such as a PDM or a smartphone. In this case, the program module 101 sends wireless signals to the detection module 100 and the infusion module 102 to achieve mutual connection. In this embodiment of the present invention, the detection module 100 and the infusion module 102 can be collectively referred to as an on-body functional module.

[0056] The wireless described in the foregoing embodiments may be achieved through, for example, but not limited to, radio frequency (RF) communication (e.g., radio frequency identification (RFID), Zigbee communication protocol, WiFi, infrared, wireless universal serial bus (USB), ultra-wideband (UWB), Communication protocols and cellular communications, such as Code Division Multiple Access (CDMA) or Global System for Mobile Communications (GSM).

[0057] Figure 2 Schematic diagram of the structure of an integrated CGM according to an embodiment of the present invention. Figure 3 Schematic diagram of the structure of a split-type CGM according to an embodiment of the present invention.

[0058] CGM includes a sensor and a transmitter, which are installed on the patient through an auxiliary installation device and inserted subcutaneously. The sensor is used to collect blood sugar content in the human body and transmit the collected blood sugar content information. The transmitter is connected to the sensor and is used to receive blood sugar data information transmitted by the sensor implanted subcutaneously and convert it into a wireless signal output. Each CGM has a unique identifier, such as a device identification code, hardware identifier, universal unique identifier, serial number, communication protocol-based identifier (such as BLE ID), manufacturer's identifier, etc. The identifier is formed by a combination of multiple randomly combined numbers and letters, which can be set on the CGM shell or packaging, and can also have different settings for different types of CGM.

[0059] Figure 2 This is a schematic diagram of the structure of an integrated CGM. That is, the sensor and transmitter of the CGM are already integrated before use, and it is a disposable product that is discarded after use. Figure 2 As shown, the integrated CGM includes a sensor 201, a housing 202, and a transmitter (not shown) disposed within the housing 202. The sensor 301 is used to detect blood glucose data from a patient's body fluids and transmit the blood glucose data to the transmitter via internal circuitry, which then transmits the data to a receiver. The identifier can be placed on the CGM's housing, packaging, or within the CGM.

[0060] Figure 3 This is a schematic diagram of the structure of a split-type CGM. That is, before use, the CGM sensor and transmitter are two separate components, packaged separately. They are integrated together during use. The split-type CGM includes a bottom housing 301 and a transmitter 302. The bottom housing is provided with a sensor 3011, while the transmitter 302 has a separate housing. The bottom housing 301 and transmitter 302 housings are provided with snap-fit ​​structures 3012 and 3022, respectively. During use, the bottom housing 301 and transmitter 302 are snapped together into a single unit via the snap-fit ​​structures. The sensor 3011 is electrically connected to the transmitter 302 via an electrical connector 3013. The sensor 301 is used to detect a patient's blood glucose data and transmits this data to the transmitter 302 via the electrical connector 3013. The transmitter 302 then transmits this data to the receiver.

[0061] In one embodiment of the present invention, both the sensor and transmitter of a split-type CGM are disposable products that are discarded after use. Therefore, the identifier can be placed on the housing or outer packaging of the sensor or transmitter. In another embodiment of the present invention, only the sensor of the split-type CGM is a disposable product, while the transmitter is a reusable product. Therefore, in this embodiment, preferably, the identifier is placed on the housing or outer packaging of the transmitter. This can reduce the frequency of binding patient information and the identifier, thereby improving the patient experience. This will be described in detail below.

[0062] When the identifier is provided on the housing or outer packaging of the CGM or transmitter, it may be provided in a form including but not limited to a QR code, a barcode, or an NFC tag.

[0063] Figure 4a is a schematic structural diagram of an integrated insulin pump according to an embodiment of the present invention; Figure 4b Schematic diagram of the structure of a split-type insulin pump according to an embodiment of the present invention.

[0064] In an embodiment of the present invention, the insulin pump is a patch-type insulin pump, that is, an insulin pump that does not include a long catheter, includes an infusion structure and a control structure, and is adhered as a whole to the patient's skin surface by a same adhesive patch. The drug is directly infused from the drug storage cartridge along the infusion needle into the subcutaneous tissue.

[0065] Each insulin pump has a unique identifier, such as a device identification code, hardware identifier, universally unique identifier, serial number, communication protocol-based identifier, manufacturer's identifier, etc. The identifier is formed by a multi-digit random combination of numbers and letters, which can be set on the housing or packaging of the insulin pump, and can also have different settings for different types of insulin pumps.

[0066] Figure 4a This is a schematic diagram of the structure of an integrated insulin pump, i.e., the infusion structure 410 and the control structure 400 of the insulin pump are arranged inside the same housing 10, the two are connected by a wire, and are affixed to a certain position on the patient's skin through an adhesive patch 420, and are discarded as a whole after one-time use; the identifier can be set on the outer housing or outer packaging of the insulin pump or inside the insulin pump.

[0067] Figure 4b This is a schematic diagram of a split-body insulin pump. The insulin pump's infusion mechanism 410 and control mechanism 400 are housed in separate housings, connected by a waterproof plug or directly snapped together and electrically connected to form a single unit. The identifier can be placed on the outer housing, packaging, or inside the insulin pump itself.

[0068] In one embodiment of the present invention, both the infusion structure and the control structure of a split-type insulin pump are disposable products that are discarded after use. Therefore, the identifier can be set on the housing or outer packaging of the infusion structure and / or the control structure. In another embodiment of the present invention, only the infusion structure of the split-type insulin pump is a disposable product, while the control structure is a reusable product. Therefore, preferably, in this embodiment, the identifier is set on the housing or outer packaging of the control structure. This can reduce the frequency of binding patient information and the identifier, thereby improving the patient experience. This will be described in detail below.

[0069] When the identifier is provided on the housing or outer packaging of the insulin pump or control structure, it may be provided in the form of, but not limited to, a QR code, a barcode, or an NFC tag.

[0070] Figures 5a-5f Schematic diagram of operations for establishing a wireless communication connection according to different embodiments of the present invention.

[0071] In the blood glucose management system, when the program module 101 is an external device such as a smart phone, PDM or tablet computer, in order to facilitate the patient to use the artificial pancreas system, wireless communication is used for data transmission and interaction between the on-body functional module (detection module 100 and / or infusion module 102) and the program module 101. Before the wireless communication connection is formally established, the detection module 100 and / or infusion module 102 sends a broadcast signal, and the program module 101 searches for the broadcast signal and identifies the content and signal strength of the broadcast signal.

[0072] In the prior art, patients need to obtain the unique device identification code of the detection module 100 and / or infusion module 102 and enter the device identification code into the program module 101 in order to identify the broadcast signal of the detection module 100 and / or infusion module 102 and establish a wireless communication connection. This step can be cumbersome, time-consuming and labor-intensive for patients. Therefore, some detection modules 100 or infusion modules 102 can send broadcast signals before establishing a communication connection. When the program module 101 searches for these broadcast signals, it can directly establish a communication connection with the signal source device. This approach eliminates the step of patients entering the device identification code of the detection module 100 and / or infusion module 102, making it more convenient for patients to use. However, when the patient is in a complex usage environment, for example, the patient is in a hospital, clinic, or other place where multiple patients are likely to gather, the patient's program module 101 may search for the broadcast signal of the detection module 100 and / or infusion module 102, and may search for the broadcast signal sent by other patients' detection modules 100 and / or infusion modules 102. The patient's program module 101 may therefore be connected to the wrong detection module 100 and / or infusion module 102, which may cause the patient's program module 101 to receive blood glucose test data from other patients, or send wrong infusion instructions to other patients' infusion modules 102, while the patient's own infusion module 102 cannot receive the correct infusion instructions, which is disadvantageous to the patient.

[0073] In view of the above problems, in some embodiments of the present invention, it is considered that when a patient establishes a wireless communication connection between his / her program module 101 and the detection module 100 and / or infusion module 102, he / she will inevitably place the program module 101 and the detection module 100 and / or infusion module 102 next to him / her. That is, the distance between the patient's own detection module 100 and / or infusion module 102 and the patient's own program module 101 is shorter than that between the detection modules 100 and / or infusion modules 102 of other patients. Therefore, when the program module 101 searches for the broadcast signal of the patient's own detection module 100 and / or infusion module 102, the signal strength obtained by the program module 101 is stronger. Moreover, if the patient intentionally makes his / her program module 101 search for a stronger broadcast signal strength to distinguish it from the broadcast signals of other patients, the patient can also actively place his / her program module 101 closer to his / her own detection module 100 and / or infusion module 102. Specific embodiments are described below.

[0074] When program module 101 establishes a wireless communication connection with detection module 100 and / or infusion module 102, Bluetooth is generally used as the communication protocol. According to the following calculation formula for Bluetooth signal strength and distance, the distance between program module 101 and detection module 100 and / or infusion module 102 can be mapped based on the Bluetooth signal strength detected by program module 101.

[0075]

[0076] Where:

[0077] d is the distance between the program module 101 and the detection module 100 and / or the infusion module 102;

[0078] RSSI is the signal strength received by the program module 101, which is a negative value;

[0079] A is the signal strength received when the program module 101 is 1 meter away from the detection module 100 and / or the infusion module 102;

[0080] n is the environmental attenuation factor.

[0081] According to formula (1), the distance d between the program module 101 and the detection module 100 and / or infusion module 102 can be determined based on the signal strength received by the program module 101. The stronger the broadcast signal strength received by the program module 101, the smaller the value of the distance d, which means that the patient's program module 101 is closer to the detection module 100 and / or infusion module 102. Conversely, when the patient holds the program module 101 close to his own detection module 100 and / or infusion module 102, the broadcast signal strength of the program module 101 searching for his own detection module 100 and / or infusion module 102 gradually increases. At the same time, the broadcast signal strength of the detection modules 100 and / or infusion modules 102 of other patients gradually decreases. Based on this, the program module 101 can distinguish the patient's own detection module 100 and / or infusion module 102 from the detection modules 100 and / or infusion modules 102 of other patients, and avoid establishing a wireless communication connection with the wrong detection module 100 and / or infusion module 102.

[0082] Generally speaking, for the detection module 100 or the infusion module 102, as long as its model and parameters do not change, the power of the broadcast signal sent is fixed after it is powered on at the factory. The signal strength of the broadcast signal decreases as the distance increases according to calculation formula (1). Therefore, when the program module 101 searches for the broadcast signal, the relative distance between the program module 101 and the detection module 100 or the infusion module 102 can be obtained based on the signal strength of the identified broadcast signal.

[0083] It should be noted that the above calculation formula (1) is only used as an exemplary description of signal strength and relative distance in this solution, and other calculation methods may be combined or used in actual product applications.

[0084] Reference Figure 5a In some embodiments of the present invention, a signal strength threshold RSSI may be preset in the program module 101. T , the broadcast signal corresponding to the signal strength threshold RSSI of the detection module 100 T100, the broadcast signal of the infusion module 102 corresponds to the signal strength threshold RSSI T102 When the patient operates the program module 101 and moves it close to the detection module 100 and / or the infusion module 102, the signal strength RSSI received by the program module 101 gradually increases until it is not less than the preset signal strength threshold RSSI. T100 and / or RSSI T102 When the program module 101 is connected to the detection module 100 and / or the infusion module 102, the signal source device can be considered to be the patient's own detection module 100 and / or the infusion module 102. At this time, the patient no longer needs to input the device identification code of the detection module 100 and / or the infusion module 102, that is, a wireless communication connection can be directly established between the program module 101 and the detection module 100 and / or the infusion module 102, which is convenient for the patient to use.

[0085] In other embodiments of the present invention, the signal strength threshold RSSI may also be preset in the detection module 100. T100 And / or preset the signal strength threshold RSSI in the infusion module 102 T102 When the detection module 100 and / or the infusion module 102 sends a broadcast signal, the broadcast signal carries a signal strength threshold RSSI of T100 and / or RSSI T102 After searching for the broadcast signal, the program module 101 identifies the strength of the broadcast signal and also identifies the preset signal strength threshold RSSI carried in the broadcast signal. T100 and / or RSSI T102 , and then compare the signal strength of the broadcast signal with the preset signal strength threshold RSSI T100 and / or RSSI T102 If the signal strength of the broadcast signal is not less than the preset signal strength threshold RSSI, T100 and / or RSSI T102 , indicating that the detection module 100 and / or infusion module 102 that sends the broadcast signal is close to the program module 101. It can be considered that the signal source device of the signal is the patient's own detection module 100 and / or infusion module 102. At this time, the patient no longer needs to enter the device identification code of the detection module 100 and / or infusion module 102, that is, the program module 101 can directly establish a wireless communication connection with the detection module 100 and / or infusion module 102, which is convenient for the patient to use. When the detection module 100 and / or infusion module 102 is produced, the preset signal strength threshold RSSI T100 and / or RSSI T102Set in the detection module 100 and / or the infusion module 102, the preset signal strength threshold RSSI suitable for the detection module 100 and / or the infusion module 102 can be set according to the hardware status, type, parameters and other characteristics of the detection module 100 and / or the infusion module 102 T100 and / or RSSI T102 The detection modules 100 and / or infusion modules 102 with different hardware status, types, parameters and other characteristics have different power levels for sending broadcast signals. Therefore, when the patient establishes a wireless communication connection, the maximum distance between the program module 101 and the detection module 100 and / or infusion module 102 is also different. In order to increase the patient's operational convenience and maintain consistency in habits, a preset signal strength threshold RSSI suitable for the detection module 100 and / or infusion module 102 is set. T100 and / or RSSI T102 , which can ensure that when the patient operates to establish a wireless communication connection, the distance between the program module 101 and the detection module 100 and / or the infusion module 102 is appropriate and consistent, thereby increasing the operational convenience for the patient and improving the patient's usage experience.

[0086] In some embodiments of the present invention, establishing a wireless communication connection by using the program module 101 to identify the signal strength sent by the detection module 100 and / or the infusion module 102 does not necessarily mean that the blood glucose management system turns off inputting the device identification code of the detection module 100 and / or the infusion module 102 to establish a wireless communication connection. The two methods of establishing a wireless communication connection can coexist, and the patient can choose the appropriate method based on his or her own condition.

[0087] Reference Figure 5b In some embodiments of the present invention, the blood glucose management system provides two operating modes for establishing a wireless communication connection for the patient. In the first operating mode, the patient operates the program module 101 to approach the detection module 100 and / or the infusion module 102. As described above, the program module 101 identifies the signal strength transmitted by the detection module 100 and / or the infusion module 102 to establish a wireless communication connection. In the second operating mode, the patient enters the device identification code of the detection module 100 and / or the infusion module 102 into the program module 101. The device identification code includes the broadcast signal information of the detection module 100 and / or the infusion module 102. Based on the device identification code, the corresponding broadcast signal can be identified to establish a wireless communication connection.

[0088] In some embodiments of the present invention, the program module 101 obtains the device identification code in ways including but not limited to manual character input by the patient, scanning of QR codes, Bluetooth transmission, voice recognition, etc. Any way of inputting the device identification code into the program module 101 can implement this solution.

[0089] In some embodiments of the present invention, when a patient desires to establish a wireless communication connection, he or she may select the first operating mode or the second operating mode on the interactive interface of the program module 101 , and the first operating mode and the second operating mode are displayed in parallel on the interactive interface of the program module 101 .

[0090] In some embodiments of the present invention, the detection module 100 and / or the infusion module 102 may be an integrated or split structure. When the detection module 100 is a split structure, its transmitter is reusable. When the infusion module 102 is a split structure, its electronic control unit, such as Figure 4a and 4b The control structure 100 shown in FIG. 1 is reusable. In the embodiment of the present invention, the device identification code of the detection module 100 corresponds to its transmitter, and the device identification code of the infusion module 102 corresponds to its electronic control unit.

[0091] In the first operating mode, the broadcast signal carries information associated with a device identification code. Program module 101 can simultaneously identify the broadcast signal and obtain the device identification code information carried therein. After the patient successfully establishes a wireless communication connection, program module 101 generates a whitelist profile for wireless communication connection partners. The whitelist profile stores information related to the detection module 100 and / or infusion module 102 with which the wireless communication connection has been established, such as the device identification code of the detection module 100 and / or infusion module 102. If the patient attempts to establish a wireless communication connection with the old detection module 100 and / or infusion module 102 without replacing the transmitter or electronic control unit, program module 101 only needs to identify the device identification code information carried in the broadcast signal. If the device identification code matches the device identification code stored in the whitelist profile, program module 101 can directly establish a wireless communication connection with the detection module 100 and / or infusion module 102 that sent the broadcast signal, without having to re-enter the device identification code or verify the signal strength of the broadcast signal. This facilitates patient operation and improves the user experience.

[0092] In some embodiments of the present invention, the whitelist profile of the program module 101 may store one or more device identification codes.

[0093] In some embodiments of the present invention, if a patient no longer wishes to establish a wireless communication connection with an old detection module 100 and / or infusion module 102, they may choose to modify or delete the corresponding whitelist profile. In this way, the program module 101 will no longer be able to directly establish a wireless communication connection with the old detection module 100 and / or infusion module 102. After the patient modifies or deletes the whitelist profile, if they need to reestablish a wireless communication connection with the corresponding detection module 100 and / or infusion module 102, they will need to re-enter the first operating mode or the second operating mode.

[0094] In other embodiments of the present invention, when the patient operates to establish a wireless communication connection again, he or she may also choose to use the first operation mode or the second operation mode, and the patient is not restricted here.

[0095] In some embodiments of the present invention, the program module 101 just searches for a signal with a preset signal strength threshold RSSI. T100 and / or RSSI T102 When the broadcast signal has the same strength, the distance between the program module 101 and the detection module 100 and / or the infusion module 102 is the maximum distance for establishing a wireless communication connection. If there is no change in the signal propagation medium, the program module 101 can establish a wireless communication connection with the detection module 100 and / or the infusion module 102 at any position within this maximum distance.

[0096] In some embodiments of the present invention, the broadcast signal strength threshold RSSI sent by the detection module 100 and / or the infusion module 102 is set. T100 and / or RSSI T102 For example, the maximum distance for establishing a wireless communication connection between the program module 101 and the detection module 100 and / or the infusion module 102 can be set to 0.5 m. That is, when the distance between the program module 101 and the detection module 100 and / or the infusion module 102 does not exceed 0.5 m, the patient can establish a wireless communication connection without entering the device identification code of the detection module 100 and / or the infusion module 102. Preferably, the maximum distance is 0.3 m. More preferably, the maximum distance is 0.1 m. In an embodiment of the present invention, the smaller the distance between the program module 101 and the detection module 100 and / or infusion module 102, the stronger the signal strength of the program module 101 identifying the patient's own detection module 100 and / or infusion module 102, and the easier it is to distinguish from the device signals of other patients. The reliability of establishing a wireless communication connection between the program module 101 and the patient's own detection module 100 and / or infusion module 102 is higher. However, if the distance between the program module 101 and the detection module 100 and / or infusion module 102 is too small, it may result in low operational convenience for the patient. Selecting an appropriate signal strength threshold can determine the appropriate distance for connecting the wireless communication connection.

[0097] In the above embodiment, when the detection module 100 and / or the infusion module 102 send the same broadcast signal strength after power-on, and the signal strength threshold RSSI preset in the program module 101 is T100 and / or RSSI T102When the maximum distance between the patient's detection module 100 and / or infusion module 102 and the program module 101 is the same each time the patient establishes a wireless communication connection, the maximum distance between the patient's detection module 100 and / or infusion module 102 and the program module 101 is the same. In other embodiments of the present invention, the maximum distance between the patient's detection module 100 and / or infusion module 102 and the program module 101 is adjustable.

[0098] For example, refer to Figure 5c In some embodiments of the present invention, the signal strength threshold RSSI T100 and / or RSSI T102 The signal strength threshold RSSI in different program modules 101 is pre-stored in the program module 101 when the program module 101 is produced. T100 and / or RSSI T102 The preset value can be different. When the patient operates to establish a wireless communication connection, the maximum distance at which the program module 101 recognizes the patient's own detection module 100 and / or infusion module 102 is also different. When the patient operates the program module 101 to approach the detection module 100 and / or infusion module 102, after entering this maximum distance, a wireless communication connection can be established between the program module 101 and the detection module 100 and / or infusion module 102.

[0099] Alternatively, in some other embodiments of the present invention, the available signal strength threshold RSSI T100 and / or RSSI T102 The list profile is pre-stored in the program module 101. When the detection module 100 and / or the infusion module 102 are shipped, the signal strength threshold RSSI suitable for the state of the detection module 100 and / or the infusion module 102 is set. T100 and / or RSSI T102 The code is encoded in the device identification code. Such a code can be composed of at least one digit, letter, special symbol, etc. Before operating to establish a wireless communication connection, the patient can first input the signal strength threshold RSSI through the interactive interface of the program module 101. T100 and / or RSSI T102 The associated code is not required to enter the complete device identification code of the detection module 100 and / or the infusion module 102. Different code mappings correspond to different signal strength thresholds RSSI T100 and / or RSSI T102 When the patient enters the code in the program module 101, the signal strength threshold RSSI corresponding to the code in the signal strength threshold list profile is called T100 and / or RSSI T102, and further corresponds to the program module 101 identifying different maximum distances of the patient's own detection module 100 and / or infusion module 102. When the patient operates the program module 101 to approach the detection module 100 and / or infusion module 102, after entering the maximum distance corresponding to this code, the program module 101 can establish a wireless communication connection with the detection module 100 and / or infusion module 102.

[0100] In some embodiments of the present invention, the signal strength threshold RSSI T100 and / or RSSI T102 The associated code can be a character, such as any Arabic numerals from 0 to 9, Greek numerals, or any letters from AZ, or any punctuation marks, without limitation. In an exemplary description, the Arabic numeral 5 represents a signal strength threshold RSSI. T5 The maximum distance for the program module 101 to establish a wireless communication connection with the detection module 100 and / or the infusion module 102 corresponding to the signal strength threshold is 0.5m. The Arabic numeral 3 represents another signal strength threshold RSSI. T3 The maximum distance for the program module 101 to establish a wireless communication connection with the detection module 100 and / or the infusion module 102 corresponding to the signal strength threshold is 0.3m. The letter A represents another signal strength threshold RSSI. TA The signal strength threshold corresponds to a maximum distance of 0.05 m for the program module 101 to establish a wireless communication connection with the detection module 100 and / or the infusion module 102. The above characters and their corresponding maximum distances are merely exemplary.

[0101] In other embodiments of the present invention, the signal strength threshold RSSI T100 and / or RSSI T102 The associated code can be at least two characters and can be composed of any Arabic numerals, Greek numerals, letters or punctuation marks, or a combination thereof, without limitation. In an exemplary description, the Arabic numeral 25 represents a signal strength threshold RSSI. T25 The maximum distance for the program module 101 to establish a wireless communication connection with the detection module 100 and / or the infusion module 102 corresponding to the signal strength threshold is 0.25m. The Arabic numeral 21 represents another signal strength threshold RSSI. T21 The maximum distance for the program module 101 to establish a wireless communication connection with the detection module 100 and / or the infusion module 102 corresponding to the signal strength threshold is 0.21m. The letter 1A represents another signal strength threshold RSSI. T1A The maximum distance for the program module 101 to establish a wireless communication connection with the detection module 100 and / or the infusion module 102 corresponding to the signal strength threshold is 0.05 m.

[0102] In some embodiments of the present invention, the signal strength threshold RSSI T100 and / or RSSI T102 The associated code can be a symbol at any position of the device identification code, and can be a continuous symbol code or an intermittent or jumping symbol code, which is not limited here. In an exemplary description, the code 1**2******** represents a signal strength threshold RSSI. T12 , where "*" represents the device identification code, i.e. the signal strength threshold RSSI T12 The corresponding code is located in the first and fourth digits of the device identification code. The patient only needs to enter "12" in the interactive interface of the program module 101, and the program module 101 will retrieve the signal strength threshold RSSI corresponding to the code "12". T12 .

[0103] In other embodiments of the present invention, the signal strength threshold RSSI T100 and / or RSSI T102 The associated code is printed separately on the detection module 100 and / or the infusion module 102 or on the packaging.

[0104] After powering on, the detection module 100 and / or infusion module 102 transmit broadcast signals at a normal power level, referred to herein as a first power level. In some prior art techniques, to facilitate wireless communication with patients, the first power level is typically set relatively high to ensure the effective range of the broadcast signal for search and identification by the program module 101. Prolonged transmission of broadcast signals at the first power level consumes excessive power for the detection module 100 and / or infusion module 102, thereby shortening their service life.

[0105] Reference Figure 5d In some embodiments of the present invention, in order to save power consumption of the detection module 100 and / or the infusion module 102 and extend its service life, the detection module 100 and / or the infusion module 102 can reduce the transmission power of the broadcast signal during the period of transmitting the broadcast signal after power-on, and transmit the broadcast signal at a second power, which is less than the first power, for example, the second power is half or one-third of the first power. Under this premise, if the preset signal strength threshold RSSI is maintained T100 and / or RSSI T102 The program module 101 just searches for the broadcast signal strength to reach the preset signal strength threshold RSSI T100 and / or RSSI T102When the program module 101 is in a state of being broadcasted, the maximum distance between the program module 101 and the detection module 100 and / or the infusion module 102 will become smaller. For example, when the broadcast signal is sent at the first power, the maximum distance for the program module 101 to establish a wireless communication connection with the detection module 100 and / or the infusion module 102 is 0.5 m. When the broadcast signal is sent at the second power, if the preset signal strength threshold RSSI is maintained, T100 and / or RSSI T102 The maximum distance for establishing a wireless communication connection between the program module 101 and the detection module 100 and / or the infusion module 102 remains unchanged, and the maximum distance for establishing a wireless communication connection between the program module 101 and the detection module 100 and / or the infusion module 102 may be reduced to 0.3 m or 0.1 m. Therefore, the patient needs to operate the program module 101 closer to the detection module 100 and / or the infusion module 102. After the program module 101 establishes a wireless communication connection with the detection module 100 and / or the infusion module 102, the detection module 100 and / or the infusion module 102 will increase the signal transmission power to maintain the long-distance wireless communication connection with the program module 101 at the third power. At this time, the effective communication distance between the program module 101 and the detection module 100 and / or the infusion module 102 is 0-10 m, which is convenient for daily use by the patient.

[0106] In the above embodiments, the communication distance values ​​are only described as examples, and different communication distance values ​​may be applicable to different products and solutions.

[0107] The detection module 100 and / or the infusion module 102 transmit a broadcast signal at a first power level after being powered on. During the period when the patient operates the program module to establish a wireless communication connection with the detection module 100 and / or the infusion module 102, due to improper operation or interference from other things, the program module 101 cannot establish a wireless communication connection with the detection module 100 and / or the infusion module 102 in a timely manner, which increases the power consumption of the detection module 100 and / or the infusion module 102 and reduces the service life of the detection module 100 and / or the infusion module 102.

[0108] For the above questions, refer to Figure 5e In some embodiments of the present invention, a time threshold is set in the detection module 100 and / or the infusion module 102. After power is applied, a broadcast signal is transmitted with a first parameter and a timer is started. If the program module 101 fails to establish a wireless communication connection with the detection module 100 and / or the infusion module 102 within the preset time threshold, the detection module 100 and / or the infusion module 102 will reduce the broadcast signal transmission parameter and transmit the broadcast signal with a second parameter. In embodiments of the present invention, the "parameter" may correspond to power or time interval.

[0109] When the "parameter" corresponds to power, as mentioned above, the second power is less than the first power, for example, the second power is half or one third of the first power. At this time, the patient needs to operate the program module 101 closer to the detection module 100 and / or the infusion module 102 to establish a wireless communication connection.

[0110] In some embodiments of the present invention, the predetermined time threshold for the detection module 100 and / or the infusion module 102 to transmit the broadcast signal at the first power after power-on is set by the manufacturer or the patient and can be set to 0-600 seconds. Preferably, the aforementioned time threshold is set to 0-60 seconds. The aforementioned values ​​are for illustrative purposes only.

[0111] In other embodiments of the present invention, when the "parameter" corresponds to a time interval, if the program module 101 fails to establish a wireless communication connection with the detection module 100 and / or the infusion module 102 within a preset time threshold, the power of the broadcast signal transmitted by the detection module 100 and / or the infusion module 102 remains unchanged, but the time interval for transmitting the broadcast signal is adjusted. For example, within the preset time threshold, the first time interval between two adjacent broadcast signals is 0.01-10 seconds. After exceeding the preset time threshold, the second time interval between two adjacent broadcast signals is 1-60 seconds. Preferably, after exceeding the preset time threshold, the time interval for transmitting the broadcast signal is increased. For example, before and after the preset time threshold, the time interval for transmitting the broadcast signal is increased from 0.1 seconds to 10 seconds. After increasing the time interval for transmitting the broadcast signal, the number of times the broadcast signal is transmitted per unit time is reduced, which can also reduce the power consumption of the detection module 100 and / or the infusion module 102 and extend the service life of the detection module 100 and / or the infusion module 102. The longer the broadcast signal sending time interval, the more power consumption is saved. However, the longer the patient waits when operating to establish a wireless communication connection, the longer the patient waits. Selecting an appropriate broadcast signal sending time interval can not only reduce power consumption but also meet the patient's usage experience.

[0112] In some embodiments of the present invention, in order to further reduce the power consumption of the detection module 100 and / or the infusion module 102, the transmission power of the broadcast signal may be reduced while increasing the transmission time interval of the broadcast signal.

[0113] In some embodiments of the present invention, if the patient is unable to establish a wireless communication connection between the program module 101 and the detection module 100 and / or infusion module 102 in a timely manner, the patient's position may change when the patient performs subsequent operations to establish a wireless communication connection, and his or her own detection module 100 and / or infusion module 102 may be close to the detection module 100 and / or infusion module 102 of other patients, thereby increasing the risk of establishing an erroneous wireless communication connection, which is not conducive to the patient's operation to establish a wireless communication connection.

[0114] For the above questions, refer to Figure 5f In some embodiments of the present invention, a time threshold can be set in the detection module 100 and / or the infusion module 102, and the timing starts after power is turned on. If the program module 101 fails to establish a wireless communication connection with the detection module 100 and / or the infusion module 102 within the preset time threshold, the blood glucose management system adds a mode of establishing a wireless communication connection by inputting the device identification code of the detection module 100 and / or the infusion module 102 in the program module 101. At this time, if the patient continues to operate to establish a wireless communication connection, he or she can continue to operate the program module 101 to search for broadcast signals, or input the device identification code of the detection module 100 and / or the infusion module 102 in the interactive interface of the program module 101, which reduces the possibility of the program module 101 connecting to the wrong detection module 100 and / or infusion module 102.

[0115] In other embodiments of the present invention, a time threshold may also be set in the program module 101. After the patient powers on the detection module 100 and / or the infusion module 102, the timing starts when the operation is performed to establish a wireless communication connection. If the program module 101 fails to establish a wireless communication connection with the detection module 100 and / or the infusion module 102 within the preset time threshold, the patient may enter the device identification code of the detection module 100 and / or the infusion module 102 in the program module 101 to establish a wireless communication connection. At this time, if the patient continues to operate to establish a wireless communication connection, he or she may continue to operate the program module 101 to search for broadcast signals, or may enter the device identification code of the detection module 100 and / or the infusion module 102 in the interactive interface of the program module 101. This also reduces the possibility of the program module 101 connecting to the wrong detection module 100 and / or infusion module 102.

[0116] In some embodiments of the present invention, the device identification code preset time threshold is set by the manufacturer or the patient and can be set to 0-600 seconds. Preferably, the time threshold is set to 0-60 seconds. The above values ​​are for illustrative purposes only.

[0117] In some embodiments of the present invention, in some cases, when the patient operates the program module 101 to search for broadcast signals, the patient may identify that the signal strength of multiple broadcast signals is not less than the preset signal strength threshold RSSI. T100 and / or RSSI T102 In this case, the program module 101 will not be able to select a broadcast signal to establish a wireless communication connection, and will promptly remind the patient that there are multiple connectable broadcast signals around the patient, and that the patient needs to change the operation location or re-operate to establish the wireless communication connection until the program module 101 only recognizes that the signal strength of one broadcast signal is not less than the preset signal strength threshold RSSI. T100 and / or RSSI T102, or prompt the patient to input the device identification code of the detection module 100 and / or the infusion module 102, so that the program module 101 establishes a wireless communication connection with the patient's own detection module 100 and / or the infusion module 102.

[0118] In some embodiments of the present invention, in order to avoid the patient from waiting for a long time during the operation to establish a wireless communication connection, the program module 101 starts timing when it starts searching and identifying the broadcast signal. For example, within 5 seconds after the program module 101 starts searching and identifying the broadcast signal, if the program module 101 does not identify a broadcast signal with a signal strength not less than a preset signal strength threshold, or identifies multiple broadcast signals with a signal strength not less than a preset signal strength threshold, the program module 101 will prompt the patient to re-operate to establish a wireless communication connection, or change the operation location. Within the next 20 seconds, if the program module 101 still does not identify a broadcast signal with a signal strength not less than the preset signal strength threshold, or still identifies multiple broadcast signals with a signal strength not less than the preset signal strength threshold, the program module 101 will prompt the patient to enter the device identification code of the detection module 100 and / or the infusion module 102 to establish a wireless communication connection. The above time values ​​are only for exemplary description.

[0119] In some embodiments of the present invention, it is considered that the program module 101 at the signal receiving end may have differences in its recognition of broadcast signals of the same signal strength due to its individual state differences. For example, after the program module 101 leaves the factory, as the use time goes by, its hardware gradually ages and its sensitivity to signal strength recognition gradually decreases. The program module 101 is generally a device that can be reused for a long time. The program module 101's recognition of the absolute strength of the broadcast signal may change during use. When the patient operates to establish a wireless communication connection, the maximum distance between the program module 101 and the detection module 100 and / or the infusion module 102 may also change, which may cause inconvenience to the patient's operating habits. Therefore, a signal correction coefficient can be set in the program module 101. The broadcast signal strength searched by the program module 101 is finally determined by the arithmetic correction result of the broadcast signal strength recognized by the program module 101 and the signal correction coefficient, and the broadcast signal strength is finally determined based on the corrected broadcast signal strength and the preset signal strength threshold RSSI. T100 and / or RSSI T102 The comparison is used to determine whether to establish a wireless communication connection. The modified broadcast signal strength can ensure that when the patient establishes a wireless communication connection, the maximum distance between the program module 101 and the detection module 100 and / or the infusion module 102 does not change significantly, for example, within a range of -0.05m to 0.05m, thereby minimizing the impact on the patient's operating habits.

[0120] In some embodiments of the present invention, the signal correction coefficient can be input into the program module 101 by the patient, or the signal correction coefficient can be stored in the program module 101. As the program module 101 is used for a longer time, the signal correction coefficient can be adjusted over time.

[0121] In some embodiments of the present invention, the correction arithmetic of the broadcast signal strength and the signal correction coefficient is multiplication or addition, or other algorithms.

[0122] Figures 6a-6f Schematic diagram of pairing and establishing communication connections according to different embodiments of the present invention.

[0123] Reference Figure 6a In some embodiments of the present invention, communication connections can be established between the program module 101, the detection module 100 and the infusion module 102. The program module 101, the detection module 100 and the infusion module 102 can all serve as signal source devices to send broadcast signals for other modules to search and pair to establish communication connections. The signal source device can send broadcast signals at low power to limit the effective range of the broadcast signal. For example, the effective range of the broadcast signal is 0 to 0.5m. When the distance between the device of other patients to establish a communication connection and the signal source device exceeds 0.5m, the broadcast signal of the signal source device cannot be searched, and the signal source device cannot be paired to establish a communication connection. According to this technical solution, the patient's own device does not need to identify the broadcast signal strength of the signal source device, and the signal source device can also pair with the patient's own device instead of other patients' devices to establish a communication connection. The specific solution will be described in detail below.

[0124] In some embodiments of the present invention, the integrity of the communication link of the blood glucose management system can be met by arbitrarily pairing the three devices, namely, the program module 101, the detection module 100 and the infusion module 102, to establish two groups of communication connections. That is, any two devices among the program module 101, the detection module 100 and the infusion module 102 are used as signal source devices, and the remaining device is used as the device for communication connection to be established. The devices for communication connection to be established are paired with the two signal source devices to establish communication connections. For example, the program module 101 and the infusion module 102 are used as signal source devices, and the detection module 100 is used as the device for communication connection to be established. The program module 101 and the detection module 100, as well as the detection module 100 and the infusion module 102, are paired to establish communication connections. Data can be directly transmitted between the program module 101 and the detection module 100, as well as between the detection module 100 and the infusion module 102, and data can be indirectly transmitted between the program module 101 and the infusion module 102 through the detection module 100.

[0125] In some embodiments of the present invention, the three devices, namely, the program module 101, the detection module 100 and the infusion module 102, can be paired with each other to establish three groups of communication connections, so as to increase the communication redundancy of the blood glucose management system. When any one group of communication connections is disconnected for some reason, the remaining two groups of communication connections can still realize the communication data transmission of the blood glucose management system, thereby enhancing the robustness of the communication system. That is, the program module 101, the detection module 100 and the infusion module 102 all act as signal source devices to send broadcast signals and as devices to be established for communication connections to search for broadcast signals. For example, the program module 101 and the detection module 100, the detection module 100 and the infusion module 102, and the infusion module 102 and the program module 101 are paired to establish communication connections respectively.

[0126] Reference Figure 6b In some embodiments of the present invention, in most usage scenarios, when patients operate the pairing to establish device communication, they usually keep the device to be established for communication close to their body, such as within the range of movement between their left and right hands. The radius of this range is generally between 0 and 0.5 meters, such as 0.05 meters or 0.1 meters. At the same time, the distance between the patient and other patients is relatively far, such as more than 0.5 meters. Therefore, no matter what device the patient uses as the broadcast signal source device, the signal source device is close to the patient's own device to be established for communication, and is far away from the devices of other patients. When the patient's own device is within the effective range of the broadcast signal source device, and the devices of other patients are outside the effective range of the broadcast signal source device, the patient's own device can be directly paired with the broadcast signal source device to establish a communication connection. There is no need to worry about pairing with the broadcast signal source device of other patients, nor is there any need to worry about the patient's own broadcast signal source device being paired with the devices of other patients, thereby ensuring the reliability of the patient's own device in establishing a wireless communication connection.

[0127] In some embodiments of the present invention, the infusion module 102 is a broadcast signal source device, and the detection module 100 and the program module 101 are devices to establish a communication connection. Upon powering on, the infusion module 102 transmits a broadcast signal, which can be a low-power Bluetooth signal with an effective range of 0 to 0.5 meters, significantly shorter than the effective communication distance of 0 to 20 meters for conventional Bluetooth signals. When a patient establishes a device pairing communication connection, they first power on the infusion module 102a, then hold their own detection module 100a and program module 101a and move them close to the infusion module 102a. When the detection module 100a and program module 101a enter the effective broadcast signal range of the infusion module 102a, the detection module 100a and program module 101a can search for the broadcast signal. Meanwhile, the detection modules 100b and program modules 101b held by other patients are outside the effective broadcast range of the infusion module 102a and cannot search for the broadcast signal. Similarly, if the patient's own detection module 100a and program module 101a are outside the effective range of the broadcast signal of other patients' infusion modules 102b, they cannot search for the broadcast signal sent by other patients' infusion modules 102b. In this scenario, when the patient's detection module 100a and program module 101a search for the broadcast signal while approaching the infusion module 102a, they can determine that the broadcast signal source device is their own infusion module 102a to establish a communication connection, and there is no need to worry about establishing an incorrect communication connection. The patient does not need to enter the device code of the infusion module 102a in the detection module 100a and program module 101a, and can directly pair and establish a wireless communication connection, saving time and effort, improving the patient's user experience, and ensuring the reliability of the communication connection of the blood glucose management system.

[0128] In the above embodiment, the infusion module 102 serves as a broadcast signal source device, and the detection module 100 and program module 101 serve as devices to be paired and established for communication. In other embodiments of the present invention, the detection module 100 serves as a broadcast signal source device, and the infusion module 102 and program module 101 serve as devices to be paired and established for communication. In still other embodiments of the present invention, the program module 101 serves as a broadcast signal source device, and the infusion module 102 and detection module 101 serve as devices to be paired and established for communication.

[0129] In other embodiments of the present invention, the broadcast signal may also be a near field communication signal, an infrared signal, a radio frequency signal, an optical signal, or a sound signal, etc., which is not limited here.

[0130] In a preferred embodiment of the present invention, the program module 101 serves as a broadcast signal source device, the infusion module 102 and the detection module 100 serve as devices to be paired to establish a communication connection, and the infusion module 102 and the program module 101, and the detection module 100 and the program module 101 are paired to establish a communication connection respectively. The program module 101 can control the infusion module 102 to perform drug infusion while also controlling the detection module 100 to perform blood glucose testing. The program module 101 can also serve as a data processing center for drug infusion data and blood glucose testing data, optimizing drug infusion data through blood glucose testing data, or optimizing blood glucose testing data through drug infusion data feedback to improve the treatment effect of the blood glucose management system. In a preferred embodiment, the program module 101 serves as a broadcast signal source device, and the patient operates the detection module 100 and the infusion module 102 to approach the program module 101 respectively. When the detection module 100 and the infusion module 102 search for the broadcast signal, it can be considered that the signal source device is the patient's program module 101, and the patient can pair and establish a communication connection without entering the device code of the program module 101.

[0131] Reference Figure 6cIn some embodiments of the present invention, a patient may use multiple infusion modules 102, detection modules 100, or program modules 101, such as detection module 100 and detection module 200. The patient may attach one detection module 100 to their arm and the other detection module 200 to their waist to detect blood glucose signals at different parts of the patient's body. After receiving the two blood glucose signals, the program module 101 may optimize the algorithm to obtain the final blood glucose signal to improve the accuracy of blood glucose testing. However, when detection module 100 and detection module 200 are both used as signal source devices, if the distance between detection module 100 and detection module 200 is less than the effective range of the broadcast signal, detection module 100 and detection module 200 may search for each other's broadcast signal and pair up to establish a communication connection. This may occupy the communication channel of detection module 100 and detection module 200, causing a communication jam. Detection module 100 or detection module 200 can no longer pair up with program module 101 or infusion module 102 to establish a communication connection, affecting the normal use of the blood glucose management system. Based on the above problem, when the infusion module 102, the detection module 100 and the program module 101 are respectively used as signal source devices, the encoding formats of their broadcast signals are different. Therefore, although the infusion module 102, the detection module 100 and the program module 101 can all send low-power Bluetooth signals, the device to be established for communication connection can distinguish whether the signal source device is the infusion module 102, the detection module 100 or the program module 101 according to the searched broadcast signal encoding format. If the signal source device corresponding to the searched broadcast signal encoding format is the same type as the device to be established for communication connection, the device to be established for communication connection can refuse to pair and establish a communication connection to avoid establishing a paired communication connection between the same devices, causing congestion in the communication channel, and ensuring the reliability of the communication connection of the blood glucose management system.

[0132] In the above-mentioned embodiment, when the detection module 100 and the detection module 200 act as signal source devices, they have both signal transmission and signal reception functions and can achieve two-way communication with other devices. In other embodiments of the present invention, the detection module 100 and the detection module 200, as signal source devices, only have the signal transmission function and will not search for or receive broadcast signals from other signal source devices. However, when the device to be paired to establish a communication connection searches for the broadcast signal sent by the detection module 100 or the detection module 200, it can still pair with the detection module 100 or the detection module 200 to establish a communication connection. Therefore, the detection module 100 and the detection module 200, as signal source devices, will not pair to establish a communication connection, thereby avoiding congestion in the communication channel and ensuring the reliability of the communication connection of the blood glucose management system.

[0133] In some embodiments of the present invention, when the detection module 100 and the detection module 200 serve as signal source devices at the same time, if the number of communication channels of the detection module 100 and the detection module 200 is sufficient, and when the distance between the detection module 100 and the detection module 200 is less than the effective range of the broadcast signal, the detection module 100 and the detection module 200 serving as signal source devices can also search for each other's broadcast signals, and the detection module 100 and the detection module 200 directly pair up to establish a communication connection. At the same time, when the patient operates his own infusion module 102 and the program module 101 to approach the detection module 100 and the detection module 200, the broadcast signals of the detection module 100 and the detection module 200 can be searched by the patient's own infusion module 102 and the program module 101, and the detection module 100 also pairs up with the infusion module 102 and the program module 101 to establish a communication connection respectively. At the same time, the detection module 200 also pairs up with the infusion module 102 and the program module 101 to establish a communication connection respectively. That is, as long as the number of communication channels of the signal source device is sufficient, it can pair up with any device to establish a communication connection. Maintaining a communication connection between detection modules 100 and 200 provides communication link redundancy for the blood glucose management system, enhancing the robustness of system data transmission. Even if the communication connection between infusion module 102 or program module 101 and either detection module 100 or detection module 200 is lost for any reason, infusion module 102 or program module 101 can still indirectly transmit data via the communication link with the other detection module, ensuring the reliability of the blood glucose management system's communication connection.

[0134] In some embodiments of the present invention, in a blood glucose management system, a patient may also use multiple infusion modules 102 or program modules 101 as signal source devices. The method of establishing a communication connection by close pairing of multiple infusion modules 102 or program modules 101 is consistent with that of multiple detection modules 100, which will not be repeated here.

[0135] In some embodiments of the present invention, in a blood glucose management system, a patient may also use the detection module 100 and the program module 101 as signal source devices at the same time, and use the infusion module 102 as a device to be paired to establish a communication connection, where the infusion module 102 is paired with the detection module 100 and the program module 101 to establish a communication connection. When the patient is operating to establish a communication connection, if the distance between the detection module 100 and the program module 101 is sufficiently far, and the effective range of the broadcast signal of the detection module 100 does not overlap with the effective range of the broadcast signal of the program module 101, the patient will move the infusion module 102 closer to the detection module 100 and the program module 101 respectively, and the infusion module 102 will be paired with the detection module 100 and the program module 101 in turn to establish a communication connection. When the patient is operating to establish a communication connection, if the effective range of the broadcast signal of the detection module 100 coincides with the effective range of the broadcast signal of the program module 101, when the patient places the infusion module 102 close to the detection module 100 and the program module 101, in the area where the effective ranges of the two broadcast signals overlap, the infusion module 102 can simultaneously search for the broadcast signals of the detection module 100 and the program module 101, and simultaneously pair with the detection module 100 and the program module 101 to establish a communication connection.

[0136] In some embodiments of the present invention, when the detection module 100 and the program module 101 serve as signal source devices at the same time, and the infusion module 102 serves as a device to be paired and established for communication connection, the detection module 100 or the program module 101 can also search for broadcast signals. The detection module 100 or the program module 101 can also serve as a device to be paired and established for communication connection. When the number of communication channels of the detection module 100 or the program module 101 is sufficient, the detection module 100 or the program module 101 searches for a broadcast signal and can pair with the signal source device of the broadcast signal to establish a communication connection. When the number of communication channels of the detection module 100 or the program module 101 is insufficient, the detection module 100 or the program module 101 searches for a broadcast signal and can refuse to pair with the signal source device of the broadcast signal to establish a communication connection, that is, pairing and establishing a communication connection between signal source devices is not allowed, and the detection module 100 and the program module 101 can each pair with the infusion module 102 to establish a communication connection.

[0137] In some embodiments of the present invention, in a blood glucose management system, a patient may use both the detection module 100 and the infusion module 102 as signal source devices, and the program module 101 as the device to be paired and established for communication. Alternatively, a patient may use both the program module 101 and the infusion module 102 as signal source devices, and the detection module 100 as the device to be paired and established for communication. The specific method for pairing and establishing a communication connection is the same as described above and will not be further described here.

[0138] In a preferred embodiment of the present invention, the patient uses the detection module 100 and the infusion module 102 as signal source devices, and uses the program module 101 as the device to be paired to establish a communication connection. When operating the pairing and establishing a communication connection, the patient holds the program module 101 close to the detection module 100 and the infusion module 102 respectively. When the program module 101 searches for a broadcast signal, it can be considered that the broadcast signal is emitted by the patient's own detection module 100 or infusion module 102. The patient does not need to enter the device code of the detection module 100 or infusion module 102, and can directly pair and establish a communication connection, saving time and effort and improving the user experience. In this preferred embodiment, the detection module 100 and the infusion module 102 can be paired to establish a communication connection, or they can be established without pairing.

[0139] Reference Figure 6d In some embodiments of the present invention, when there are multiple different broadcast signal source devices, for example, the infusion module 102 and the program module 101 can both transmit low-power broadcast signals. Due to the short effective range of the broadcast signals, the broadcast signal ranges of the infusion module 102 and the program module 101 may not overlap. When the patient operates to establish a paired communication connection, the patient can first operate their own detection module 100a close to the infusion module 102, enter the effective broadcast signal range of the infusion module 102, and pair with the infusion module 102 to establish a wireless communication connection, and then operate the detection module 100a close to the program module 101, enter the effective broadcast signal range of the program module 101, and pair with the program module 101 to establish a wireless communication connection. Alternatively, the patient can first operate their own detection module 100a close to the program module 101, enter the effective broadcast signal range of the program module 101, and pair with the program module 101 to establish a wireless communication connection, and then operate the detection module 100a close to the infusion module 102, enter the effective broadcast signal range of the infusion module 102, and pair with the infusion module 102 to establish a wireless communication connection. The detection modules 100b of other patients do not enter the effective range of the corresponding broadcast signals during the above pairing process. Similarly, the detection module 100a of the patient will not enter the effective range of the broadcast signals of other patients. Therefore, the detection module 100a of the patient will only search for the broadcast signals emitted by its own infusion module 102 and program module 101, and the broadcast signals emitted by the patient's infusion module 102 and program module 101 will only be searched by its own detection module 100a. The detection module 100a can directly pair with the signal source device to establish a communication connection without entering the device code of the infusion module 102 and program module 101, which saves time and effort and ensures the reliability of the communication connection of the patient's blood glucose management system.

[0140] In the above embodiment, the infusion module 102 and the program module 101 function as broadcast signal source devices, and the detection module 100 functions as a device to be paired with to establish a communication connection. In other embodiments of the present invention, the detection module 100 and the program module 101 function as broadcast signal source devices, and the infusion module 102 functions as a device to be paired with to establish a communication connection. In still other embodiments of the present invention, the infusion module 102 and the detection module 101 function as broadcast signal source devices, and the program module 101 functions as a device to be paired with to establish a communication connection.

[0141] Reference Figure 6e In some embodiments of the present invention, when the effective ranges of the broadcast signals of the infusion module 102 and the program module 101 overlap, when the patient operates the detection module 100a to approach the infusion module 102 and the program module 101, the patient may enter the overlapping area of ​​the broadcast signals of the infusion module 102 and the program module 101. Here, the detection module 100a can simultaneously search for the broadcast signals of the infusion module 102 and the program module 101, and the patient can operate to simultaneously pair the detection module 100a with the infusion module 102 and the detection module 100a with the program module 101 to establish communication connections. During the above pairing process, the detection modules 100b of other patients will not enter the effective range of the broadcast signals of the infusion module 102 and the program module 101. Similarly, the detection module 100a of the patient will not enter the effective range of the broadcast signals of other patients. Therefore, the detection module 100a of the patient will only search for the broadcast signals emitted by its own infusion module 102 and the program module 101, and the broadcast signals emitted by the patient's infusion module 102 and the program module 101 will only be searched by its own detection module 100a. The detection module 100a can directly pair with the signal source device to establish a communication connection without entering the device code of the infusion module 102 and the program module 101, thereby ensuring the reliability of the communication connection of the patient's blood glucose management system.

[0142] In the above embodiment, the infusion module 102 and the program module 101 function as broadcast signal source devices, and the detection module 100 functions as a device to be paired with to establish a communication connection. In other embodiments of the present invention, the detection module 100 and the program module 101 function as broadcast signal source devices, and the infusion module 102 functions as a device to be paired with to establish a communication connection. In still other embodiments of the present invention, the infusion module 102 and the detection module 101 function as broadcast signal source devices, and the program module 101 functions as a device to be paired with to establish a communication connection.

[0143] Reference Figure 6fIn some embodiments of the present invention, even if low-power Bluetooth technology is used to reduce the effective range of the broadcast signal, in some usage scenarios, such as hospitals, patients are relatively concentrated, and the distance between each patient's detection module 100, program module 101, and infusion module 102 is short. When operating the pairing to establish a communication connection, it is still inevitable to search for the wrong broadcast signal, resulting in device pairing errors. For example, after the patient's infusion module 102a is powered on, it sends a broadcast signal as a signal source device. At the same time, another patient also powers on his infusion module 102b and sends a broadcast signal as another signal source device. The distance between the two patients is relatively close, and the distance between the infusion module 102a and the infusion module 102b may be only 0.3m. This distance causes the effective range of the broadcast signals of the two infusion modules 102a / 102b to overlap. When the patient operates his own program module 101a to approach his own infusion module 102a to try to pair and establish a communication connection, he may enter the other patient's The infusion module 102b is within the effective range of the broadcast signal of the infusion module 102b, causing the program module 101a to recognize the broadcast signals of the two infusion modules 102a / 102b. At this time, the patient cannot tell which broadcast signal comes from his own infusion module. At this time, the patient can still input the device code (SN) of the infusion module 102a into the program module 101a to pair the infusion module 102a and the program module 101a to establish a communication connection, or input the device code of the infusion module 102a into the detection module 100a to pair the infusion module 102a and the detection module 100a to establish a communication connection.

[0144] In some embodiments of the present invention, although the detection module 100, program module 101, or infusion module 102 transmits broadcast signals at a relatively low power while acting as a signal source device, after formally pairing with the device to be paired and establishing a communication connection signal, the signal source device changes to transmitting a communication signal, which is used to achieve end-to-end data transmission. At this time, it is also necessary to increase the transmission power of the communication signal to increase the effective range of the communication signal, for example, to increase the effective range of the communication signal to 0-10 meters, so that the patient or their guardian can remotely control the program module 101. Of course, if the patient does not need to remotely control the program module 101, the communication signal transmission power of the signal source device can still be maintained at a relatively low state to reduce the power consumption of the signal source device.

[0145] In some embodiments of the present invention, the communication signal is a Bluetooth signal.

[0146] In some other embodiments of the present invention, the communication signal may also be a near field communication signal, an infrared signal, a radio frequency signal, an optical signal, or a sound signal, etc., which is not limited here.

[0147] In some embodiments of the present invention, in order to further ensure the reliability of the pairing and establishment of a wireless communication connection between the program module 101, the detection module 100, and the infusion module 102, when the program module 101, the detection module 100, and the infusion module 102 are paired to establish a wireless communication connection, a confirmation instruction from the patient is also required.

[0148] In some embodiments of the present invention, although the signal source device sends a broadcast signal using low-power Bluetooth, the effective range of the broadcast signal is 0 to 0.5 m. This effective range provides sufficient space for the patient to operate the pairing and establish a communication connection. In order to further ensure the reliability of the pairing and establishment of the communication connection and avoid establishing an erroneous communication connection, the patient can directly touch the signal source device and the device to be paired to establish a communication connection when pairing and establishing a communication connection. At this time, the effective range of the broadcast signal of the signal source device can be adjusted to a smaller value, such as 5 cm or 3 cm. The smaller the effective range of the broadcast signal, the more it can prevent the patient from establishing an erroneous communication connection and improve the communication reliability of the blood glucose management system.

[0149] In summary, the present invention discloses a blood glucose management system. When the patient operates to establish a communication connection, at least one device among the detection module, infusion module and program module acts as a signal source device to send a low-power broadcast signal, and at least one device acts as a device to be paired to establish a communication connection. The patient operates the device to be paired to establish a communication connection to approach the signal source device. When the device to be paired to establish a communication connection enters the effective range of the broadcast signal, it can search for the broadcast signal and pair with the signal source device to establish a communication connection. Since the effective range of the broadcast signal is small, this range is generally smaller than the normal distance between the two devices. This can avoid the device to be paired to establish a communication connection from searching for the wrong broadcast signal and establishing a wrong communication connection. When the device to be paired to establish a communication connection searches for the broadcast signal, it can consider that the signal source device is the patient's own device. The patient does not need to enter the device code, and the device to be paired to establish a communication connection and the signal source device can automatically establish a communication connection, which saves time and effort and improves the patient's user experience.
