Description

Technical Field

[0001] This utility model mainly relates to the field of medical devices, and in particular to a blood glucose management system. Background Technology

[0002] In healthy individuals, the pancreas automatically secretes the necessary insulin / glucagon based on blood glucose levels, thus maintaining a reasonable range of blood sugar fluctuations. However, in diabetic patients, pancreatic function is abnormal, and the pancreas is unable to secrete the required insulin normally. Diabetes is a metabolic disease and is a lifelong condition. Current medical technology cannot cure diabetes; it can only control the occurrence and development of diabetes and its complications by stabilizing blood sugar levels.

[0003] Diabetic patients need to have their blood glucose levels checked before injecting insulin. Currently, most methods involve continuous glucose monitoring (CGM) using a disposable percutaneous sensor inserted into the skin. This device measures the glucose concentration in the interstitial fluid and transmits the data wirelessly to an external device for the patient to view. The external device then wirelessly transmits the required insulin dosage to the insulin pump, controlling the pump to deliver the insulin subcutaneously, thus forming a glucose management system.

[0004] In existing blood glucose management systems, before establishing a wireless communication connection between the external device (referred to as the program module in this solution) and the blood glucose testing device (referred to as the testing module in this solution) and / or the insulin pump (referred to as the infusion module in this solution), the patient often needs to input the device identification code of the blood glucose testing device and / or the insulin pump so that the external device can identify the broadcast signal of the blood glucose testing device and / or the insulin pump. The operation of inputting the device identification code is cumbersome and inconvenient for the patient.

[0005] Therefore, there is an urgent need for a blood glucose management system that can eliminate the need for inputting device identification codes and facilitate patient operation to establish communication connections. Utility Model Content

[0006] This utility model discloses a blood glucose management system. When a patient establishes a communication connection, at least one device among the detection module, infusion module, and program module acts as a signal source device, sending a low-power broadcast signal. At least one device acts as a device to be paired for establishing a communication connection. The patient operates the device to be paired to approach the signal source device. When the device to be paired enters the effective range of the broadcast signal, it can detect the broadcast signal and pair with the signal source device to establish a communication connection. Since the effective range of the broadcast signal is relatively small, generally smaller than the conventional distance between the two devices, it can avoid the device to be paired to detect the wrong broadcast signal and establish an incorrect communication connection. When the device to be paired detects the broadcast signal, it can recognize the signal source device as the patient's own device. The patient does not need to enter a device code; the device to be paired and the signal source device can automatically establish a communication connection, saving time and effort and improving the patient's user experience.

[0007] This utility model discloses a blood glucose management system, including at least one detection module for continuously detecting a patient's current blood glucose level when attached to the skin surface; at least one infusion module for infusing the patient with the required medication; and at least one program module for controlling the operation of the detection module and the infusion module, generating a medication infusion command based on the current blood glucose level detected by the detection module, and controlling the infusion module to perform medication infusion. The detection module, infusion module, and program module can be paired to establish a communication connection for data exchange. During the pairing and communication connection establishment process, at least one device among the detection module, infusion module, and program module acts as a signal source device, transmitting a low-power broadcast signal. At least one device, acting as a device to be paired for communication connection establishment, approaches the signal source device. When the device to be paired enters the effective range of the broadcast signal from the signal source device, the broadcast signal can be detected, and a communication connection can be established with the signal source device.

[0008] According to one aspect of this utility model, the effective range of the broadcast signal is 0 to 0.5 m.

[0009] According to one aspect of this utility model, the broadcast signal is a Bluetooth signal.

[0010] According to one aspect of the present invention, the device to be paired and establishes 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 the at least two signal sources do not overlap, the devices to be paired and establish communication connections approach the signal source devices in sequence to enter the effective range of the broadcast signals, and pair and establish communication connections with the signal source devices respectively.

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

[0013] According to one aspect of this utility model, communication connections are established between the same signal source devices without pairing.

[0014] According to one aspect of this utility model, when the detection module, infusion module, or program module serves as a signal source device, they transmit broadcast signals with different encoding formats.

[0015] According to one aspect of this utility model, the signal source device does not search for or 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 this utility model, after the signal source device and the device to be paired to establish a communication connection are paired and a communication connection is established, 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 this utility model, the effective range of the communication signal is 0 to 10 m.

[0019] According to one aspect of this utility model, 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 this utility model, before the signal source device and the device to be paired to establish a communication connection are paired to establish a wireless communication connection, the patient's confirmation is required.

[0023] Compared with the prior art, the technical solution of this utility model has the following advantages:

[0024] In the blood glucose management system disclosed in this utility model, when a patient establishes a communication connection, at least one device among the detection module, infusion module, and program module acts as a signal source device, sending a low-power broadcast signal. At least one device acts as a device to be paired for establishing a communication connection. The patient operates the device to be paired 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 detect the broadcast signal and pair with the signal source device to establish a communication connection. Since the effective range of the broadcast signal is relatively small, generally smaller than the conventional distance between the two devices, it can avoid the device to be paired to establish a communication connection from detecting the wrong broadcast signal and establishing an incorrect communication connection. When the device to be paired to establish a communication connection detects the broadcast signal, it can recognize the signal source device as 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 with 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 with each other to establish communication connections, making the communication methods flexible, convenient for patients to operate, and improving the patient's user experience.

[0026] Furthermore, the effective range of the broadcast signal is 0–0.5 m, which is generally smaller than the conventional distance between patients. When a patient is establishing a communication connection, the distance between the patient's signal source device and the device to be paired for establishing a communication connection, as well as other patients' devices, is greater than the effective range of the broadcast signal. When the device to be paired for establishing a communication connection detects the broadcast signal, it can be assumed that the distance between the device to be paired for establishing a communication connection and the signal source device is close enough. This signal source device is the one the patient wants to pair with for establishing a communication connection, rather than another patient's signal source device, thus avoiding the establishment of incorrect communication connections.

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

[0028] Furthermore, when the number of communication channels for signal source devices is insufficient, signal source devices cannot be paired to establish communication connections to avoid occupying communication channels and affecting the communication connection between the signal source device and the device to be paired. When the number of communication channels for signal source devices is sufficient, signal source devices of the same type can be paired to establish communication connections, thereby increasing the communication link redundancy of the blood glucose management system 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 acting as signal source devices. Different types of signal source devices send broadcast signals with different encoding formats. While sending broadcast signals, the signal source device can also search for and receive broadcast signals from other signal sources. When the encoding format of the broadcast signal it finds is the same as its own type, it can 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 devices do not have the function of searching for or receiving broadcast signals, and the signal source devices will not pair up to establish a communication connection, so as to avoid occupying the communication channels of the signal source devices and affecting the communication connection between the signal source devices and the devices to be paired to establish a communication connection.

[0031] Furthermore, after the signal source device and the device to be paired establish a communication connection, the transmission power of the communication signal is increased to expand the effective range of the communication signal, making it easier for patients or caregivers to use the program module remotely and control the blood glucose management system. If the patient does not need to use the program module remotely, the transmission power of the communication signal may not be increased after the signal source device and the device to be paired establish a communication connection, in order to reduce the power consumption of the signal source device.

[0039] As mentioned earlier, 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 testing device (referred to as a testing module in this solution) and / or an insulin pump (referred to as an infusion module in this solution), the patient often needs to input the device identification code of the blood glucose testing device and / or insulin pump so that the external device can identify the broadcast signal of the blood glucose testing device and / or insulin pump. The operation of inputting the device identification code is cumbersome and inconvenient for the patient.

[0040] To address this issue, this invention provides a blood glucose management system. When a patient establishes a communication connection, at least one device from the detection module, infusion module, and program module acts as a signal source device, transmitting a low-power broadcast signal. At least one device acts as a device to be paired for communication connection establishment. The patient operates the device to be paired to approach the signal source device. When the device to be paired enters the effective range of the broadcast signal, it can detect the broadcast signal and pair with the signal source device to establish a communication connection. Because the effective range of the broadcast signal is relatively small, generally smaller than the conventional distance between the two devices, it avoids the device to be paired to detect the wrong broadcast signal and establish an incorrect communication connection. When the device to be paired detects the broadcast signal, it recognizes the signal source device as the patient's own device. The patient does not need to input a device code; the device to be paired and the signal source device can automatically establish a communication connection, saving time and effort and improving the patient's user experience.

[0041] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments should not be construed as limiting the scope of the present invention.

[0042] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not necessarily drawn to actual scale; for example, the thickness, width, length, or distance of some units may be enlarged relative to other structures.

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

[0044] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined or described in a figure, it will not need to be discussed further in the subsequent description of the figures.

[0045] Figure 1 This is a schematic diagram illustrating the module relationships of a general blood glucose management system.

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

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

[0048] The infusion module 102 includes the necessary mechanical structures and electronic control units for infusing blood glucose regulating drugs such as insulin and glucagon, including a drug reservoir, drive structure, infusion tubing and infusion needle, power supply, and circuit board. It is controlled by the program module 101. Generally, the infusion module 102 is an insulin pump, and the electronic control unit includes a transmitter, memory, processor, and communication interface. Based on the current insulin infusion volume data issued by the program module 101, the infusion module 102 infuses the required insulin into the patient's body. Simultaneously, the infusion status of the infusion module 102 can be fed back to the program module 101 in real time.

[0049] The program module 101 controls the operation of the detection module 100 and the infusion module 102. Based on the blood glucose value detected by the detection module 100, the program module 101 generates an insulin infusion command and controls the infusion module 102 to perform the infusion. It includes a memory, a processor, a communication interface, a display, and a patient interface. The memory stores programming instructions, which the processor can execute. The program module 101 is connected to both the detection module 100 and the infusion module 102. This connection can be a conventional electrical connection or a wireless connection.

[0050] The embodiments of this utility model do not limit the specific locations 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 this invention, the three components are electrically connected to form a single integrated structure. Therefore, all three are adhered to the same location on the patient's skin. By connecting the three modules into a single unit and adhering them to the same location, the number of devices that need to be applied to the patient's skin is reduced, thereby lessening the interference to the patient's activities caused by having too many devices. Simultaneously, it effectively solves the problem of reliable wireless communication between separate devices, further enhancing the patient experience.

[0052] In another embodiment of this invention, the program module 101 and the infusion module 102 are interconnected to form an integral structure, while the detection module 100 is separately disposed in another structure. In this case, the detection module 100 and the program module 101 send wireless signals to each other to achieve interconnection. Therefore, the program module 101 and the infusion module 102 are attached to one location on the patient's skin, while the detection module 100 is attached to other locations on the patient's skin.

[0053] In another embodiment of this invention, the program module 101 and the detection module 100 are interconnected to form a single device, while the infusion module 102 is separately disposed in another structure. The infusion module 102 and the program module 101 transmit wireless signals to each other to achieve interconnection. Therefore, the program module 101 and the detection module 100 can be attached to one location on the patient's skin, while the infusion module 102 can be attached to other locations on the patient's skin.

[0054] In another embodiment of this invention, the three components are disposed in different structures. Therefore, they are respectively attached to different locations on the patient's skin. At this time, the program module 101 communicates wirelessly with the detection module 100 and the infusion module 102 to establish a connection.

[0055] In another embodiment of this invention, the three modules are disposed 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. Control of the detection module 100 and the infusion module 102 is achieved through a handheld or portable device, such as a PDM or a smartphone. In this case, the program module 101 sends wireless signals to both the detection module 100 and the infusion module 102 to establish a connection. In this embodiment of the invention, the detection module 100 and the infusion module 102 can be collectively referred to as on-body functional modules.

[0056] The wireless communication described in the foregoing embodiments can be, for example, but not limited to, radio frequency (RF) communication (e.g., 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 This is a structural schematic diagram of an integrated CGM according to an embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of a split CGM according to an embodiment of the present invention.

[0058] A CGM consists of a sensor and a transmitter. It is implanted subcutaneously into the patient using an auxiliary installer. The sensor collects and transmits blood glucose levels. The transmitter connects to the sensor, receives the blood glucose data, and converts it into a wireless signal for output. Each CGM has a unique identifier, such as a device identification code, hardware identifier, universally unique identifier, serial number, protocol-based identifier (e.g., BLE ID), or manufacturer identifier. This identifier is a combination of random numbers and letters and can be placed on the CGM's casing or packaging, and may vary depending on the type of CGM.

[0059] Figure 2 This is a schematic diagram of an integrated CGM (Continuous Gauge Transmitter). The CGM's sensor and transmitter are integrated before use, and it is a single-use 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 201 detects blood glucose data from the patient's body fluids and transmits this data to the transmitter via internal circuitry, which then transmits it to the receiver. Identifiers can be located on the outer housing or packaging of the CGM, or inside the CGM itself.

[0060] Figure 3 This is a schematic diagram of a split-type CGM. Before use, the sensor and transmitter of the CGM are two separate components, packaged separately, and integrated together only during use. The split-type CGM includes a base shell 301 and a transmitter 302. The sensor 3011 is mounted on the base shell, and the transmitter 302 has a separate housing. The base shell 301 and the transmitter 302 housings are respectively equipped with snap-fit ​​structures 3012 and 3022. During use, the base shell 301 and the transmitter 302 are snapped together into a single unit using these snap-fit ​​structures. The sensor 3011 is electrically connected to the transmitter 302 via an electrical connector 3013. The sensor 301 detects the patient's blood glucose data and transmits this data to the transmitter 302 via the electrical connector 3013, which then transmits it to the receiver.

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

[0062] When the identifier is set on the housing or outer packaging of the CGM or transmitter, it can be set in the form of, but is not limited to, QR codes, barcodes, or NFC tags.

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

[0064] In this embodiment of the invention, the insulin pump is a patch-type insulin pump, that is, an insulin pump that does not include a long catheter. It includes an infusion structure and a control structure, and is entirely attached to the patient's skin surface by the same adhesive patch. The drug is directly infused from the reservoir along the infusion needle to 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 identifier, etc. The identifier is formed by a combination of multiple random numbers and letters, which can be set on the insulin pump housing or packaging, and can also have different settings depending on the type of insulin pump.

[0066] Figure 4a This is a schematic diagram of an integrated insulin pump, in which the infusion structure 410 and the control structure 400 of the insulin pump are located inside the same housing 10. The two are connected by wires and are attached to a certain position on the patient's skin by an adhesive patch 420. The whole unit is discarded after single use. The identifier can be set on the outer housing of the insulin pump, the outer packaging, or inside the insulin pump.

[0067] Figure 4b This is a schematic diagram of a split-type insulin pump, where the infusion structure 410 and control structure 400 are housed in two separate housings. These are connected by a waterproof plug or directly snapped together and electrically connected to form a single unit. Identifiers can be placed on the outer casing or packaging of the infusion and / or control structures, or inside the insulin pump.

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

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

[0070] Figures 5a-5f This diagram illustrates the operation of establishing wireless communication connections in 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 smartphone, PDM, or tablet, in order to facilitate the patient's use of the artificial pancreas system, the on-body functional modules (detection module 100 and / or infusion module 102) and the program module 101 use wireless communication for data transmission and interaction. Before the formal establishment of the wireless communication connection, the detection module 100 and / or infusion module 102 send broadcast signals, and the program module 101 searches for broadcast signals and identifies the content and strength of the broadcast signals.

[0072] In existing technologies, patients need to obtain the unique device identification code of the detection module 100 and / or infusion module 102 and input the device identification code into the program module 101 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 and time-consuming 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 detects these broadcast signals, it can directly establish a communication connection with the signal source device. This method eliminates the need for patients to input the device identification code of the detection module 100 and / or infusion module 102, making it more convenient for patients to use. However, when patients are in complex environments, such as hospitals or clinics where multiple patients are likely to gather, the patient's program module 101 may search for broadcast signals from other patients' detection modules 100 and / or infusion modules 102 while searching for broadcast signals from the detection module 100 and / or infusion module 102. As a result, the patient's program module 101 may connect to the wrong detection module 100 and / or infusion module 102. This could cause the patient's program module 101 to receive blood glucose test data from other patients or send incorrect infusion instructions to other patients' infusion modules 102, while its own infusion module 102 cannot receive the correct infusion instructions. This is detrimental to the patient.

[0073] In view of the above problems, in some embodiments of this utility model, considering that when a patient establishes a wireless communication connection between their program module 101 and the detection module 100 and / or infusion module 102, they will inevitably place the program module 101 and the detection module 100 and / or infusion module 102 near themselves, that is, the distance between the patient's own detection module 100 and / or infusion module 102 and their own program module 101 is shorter than that between the detection module 100 and / or infusion module 102 of other patients and their own program module 101. 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 it obtains is stronger. Furthermore, if the patient intends to make their program module 101 find a stronger broadcast signal strength to distinguish it from the broadcast signals of other patients, the patient can also actively move their program module 101 closer to their own detection module 100 and / or infusion module 102. Specific implementation methods are described below.

[0074] When establishing a wireless communication connection between program module 101 and detection module 100 and / or infusion module 102, Bluetooth is generally used as the communication protocol. According to the following formula for calculating 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] In the formula:

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

[0078] RSSI is the signal strength received by program module 101, and this value is negative.

[0079] A represents 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 degradation factor.

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

[0082] Generally speaking, for the detection module 100 or the infusion module 102, as long as their model and parameters do not change, the power of the broadcast signal sent after being powered on at the factory is fixed. The signal strength of the broadcast signal decreases with the increase of distance according to the calculation formula (1). Therefore, when the program module 101 searches for the broadcast signal, it can obtain the relative distance between the program module 101 and the detection module 100 or the infusion module 102 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 scheme. In actual product applications, other calculation methods may be combined or used.

[0084] Reference Figure 5a In some embodiments of this utility model, a signal strength threshold RSSI can be preset in program module 101. TThe broadcast signal of the detection module 100 corresponds to the RSSI signal strength threshold. 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 closes to their own detection module 100 and / or 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 In this case, the signal source device of the signal can be considered to be the patient's own detection module 100 and / or infusion module 102. At this time, the patient no longer needs to input the device identification code of the detection module 100 and / or infusion module 102. 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.

[0085] In other embodiments of this invention, a signal strength threshold RSSI can be preset in the detection module 100. T100 And / or a preset signal strength threshold RSSI is provided in the infusion module 102. T102 When the detection module 100 and / or the infusion module 102 send a broadcast signal, the broadcast signal carries a signal strength threshold RSSI that is equal to the preset signal strength threshold. T100 and / or RSSI T102 According to relevant information, after detecting a broadcast signal, program module 101 needs to identify the strength of the broadcast signal and, at the same time, identify the preset signal strength threshold RSSI carried in the broadcast signal. T100 and / or RSSI T102 Then the signal strength of the broadcast signal is compared with the preset signal strength threshold RSSI. T100 and / or RSSI T102 The comparison is performed; if the signal strength of the broadcast signal is not less than its preset signal strength threshold RSSI... T100 and / or RSSI T102 This indicates that the detection module 100 and / or infusion module 102 sending the broadcast signal is close to the program module 101. Therefore, the signal source device can be considered to be the patient's own detection module 100 and / or infusion module 102. In this case, the patient no longer needs to input the device identification code of the detection module 100 and / or infusion module 102; a wireless communication connection can be directly established between the program module 101 and the detection module 100 and / or infusion module 102, facilitating patient use. When the detection module 100 and / or infusion module 102 are manufactured, a preset signal strength threshold RSSI is set. T100 and / or RSSI T102The preset signal strength threshold RSSI can be set in the detection module 100 and / or the infusion module 102 according to the hardware status, type, parameters and other characteristics of each individual detection module 100 and / or infusion module 102. T100 and / or RSSI T102 Different detection modules 100 and / or infusion modules 102, with varying hardware states, types, and parameters, transmit broadcast signals at different power levels. Consequently, the maximum distance between the program module 101 and the detection module 100 and / or infusion module 102 varies when the patient establishes a wireless communication connection. To enhance patient convenience and maintain consistency of habits, a preset signal strength threshold (RSSI) suitable for each individual detection module 100 and / or infusion module 102 is set. T100 and / or RSSI T102 This ensures that the distance between the program module 101 and the detection module 100 and / or the infusion module 102 is appropriate and consistent when the patient is establishing a wireless communication connection, which increases the convenience of operation for the patient and improves the patient's user experience.

[0086] In some embodiments of this utility model, the wireless communication connection is established by the program module 101 identifying the signal strength sent by the detection module 100 and / or the infusion module 102. This does not necessarily mean that the blood glucose management system turns off the input of the device identification code of the detection module 100 and / or the infusion module 102 to establish a wireless communication connection. Both methods of establishing a wireless communication connection can coexist, and patients can choose the appropriate method based on their own conditions.

[0087] Reference Figure 5b In some embodiments of this utility model, the blood glucose management system provides patients with two operating modes for establishing a wireless communication connection simultaneously. In the first operating mode, the patient operates the program module 101 close to the detection module 100 and / or the infusion module 102. As mentioned above, the program module 101 identifies the signal strength sent by the detection module 100 and / or the infusion module 102 to establish a wireless communication connection. In the second operating mode, the patient inputs the device identification code of the detection module 100 and / or the infusion module 102 into the program module 101. The device identification code contains 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 this utility model, the program module 101 obtains the device identification code in ways including but not limited to manual input of characters by the patient, scanning of a QR code, Bluetooth transmission, voice recognition, etc. Any method that can input the device identification code into the program module 101 can realize this solution.

[0089] In some embodiments of this utility model, when a patient wishes to establish a wireless communication connection, he / she can select a first operation mode or a second operation mode in the interactive interface of the program module 101. The first operation mode and the second operation mode are displayed in parallel in the interactive interface of the program module 101.

[0090] In some embodiments of this utility model, the detection module 100 and / or the infusion module 102 can be an integrated or separate structure. When the detection module 100 is a separate structure, its transmitter is reusable. When the infusion module 102 is a separate structure, its electronic control unit, such as... Figure 4a and 4b The control structure 100 shown is reusable. In this embodiment of the 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 the device identification code. The program module 101 can identify the broadcast signal and simultaneously obtain the device identification code information it carries. After the patient successfully establishes a wireless communication connection, the program module 101 generates a whitelist of objects that can establish wireless communication connections. The whitelist stores relevant information about the detection module 100 and / or infusion module 102 that have already established wireless communication connections, such as the device identification codes of the detection module 100 and / or infusion module 102. If the patient re-establishes a wireless communication connection with the old detection module 100 and / or infusion module 102 without replacing the transmitter or control unit, the program module 101 only needs to identify the device identification code information carried in the broadcast signal. If it matches the device identification code stored in the whitelist, the 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 needing to re-enter the device identification code or identify the signal strength of the broadcast signal. This simplifies patient operation and improves the user experience.

[0092] In some embodiments of this utility model, the whitelist profile of program module 101 may store one or more device identifier codes.

[0093] In some embodiments of this invention, when a patient no longer wishes to establish a wireless communication connection with an older detection module 100 and / or infusion module 102, they can choose to modify or delete the corresponding whitelist profile. This prevents the program module 101 from directly establishing a wireless communication connection with that detection module 100 and / or infusion module 102. After modifying or deleting the whitelist profile, if the patient needs to re-establish a wireless communication connection with the corresponding detection module 100 and / or infusion module 102, they need to re-enter the first or second operating mode.

[0094] In other embodiments of this invention, when the patient re-establishes a wireless communication connection, they may choose to use either the first operating mode or the second operating mode, without imposing any restrictions on the patient.

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

[0096] In some embodiments of this invention, the RSSI threshold of the broadcast signal strength transmitted by the detection module 100 and / or the infusion module 102 is set. T100 and / or RSSI T102 The corresponding maximum distance can be set to 0.5m for the program module 101 to establish a wireless communication connection with the detection module 100 and / or the infusion module 102. That is, when the distance between the program module 101 and the detection module 100 and / or the infusion module 102 does not exceed 0.5m, the patient does not need to input the device identification code of the detection module 100 and / or the infusion module 102 to establish a wireless communication connection. Preferably, the maximum distance is 0.3m. More preferably, the maximum distance is 0.1m. In this embodiment of the invention, the smaller the distance between the program module 101 and the detection module 100 and / or the infusion module 102, the stronger the signal strength of the program module 101 in identifying the patient's own detection module 100 and / or infusion module 102, and the easier it is to distinguish the device signals from 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 convenience for the patient's operation. Selecting an appropriate signal strength threshold can determine the appropriate distance for establishing a wireless communication connection.

[0097] In the above embodiments, when the broadcast signal strengths sent by the detection module 100 and / or the infusion module 102 after power-on are the same, and the preset signal strength threshold RSSI in the program module 101 is... T100 and / or RSSI T102When the condition remains unchanged, the maximum distance at which the program module 101 identifies the patient's own detection module 100 and / or infusion module 102 is also the same each time a wireless communication connection is established. In other embodiments of this invention, the maximum distance at which the program module 101 identifies the patient's own detection module 100 and / or infusion module 102 can be adjusted.

[0098] For example, refer to Figure 5c In some embodiments of this utility model, the signal strength threshold RSSI T100 and / or RSSI T102 The signal strength threshold RSSI in different program modules 101 is pre-stored in program module 101 during the manufacturing process. T100 and / or RSSI T102 The preset values ​​can be different. When the patient operates to establish a wireless communication connection, the maximum distance at which the program module 101 identifies the patient's own detection module 100 and / or infusion module 102 will also be 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 other embodiments of this invention, the available signal strength threshold RSSI T100 and / or RSSI T102 The signal strength threshold RSSI suitable for the state of the detection module 100 and / or infusion module 102 is pre-stored in the program module 101 in the form of a list profile. When the detection module 100 and / or infusion module 102 leaves the factory, the threshold is set to be stored in the program module 101. T100 and / or RSSI T102 The encoding is in the device identification code. Such encoding can consist of at least one number, letter, special symbol, or other character. Before establishing a wireless communication connection, the patient can input the signal strength threshold RSSI through the interactive interface of program module 101. T100 and / or RSSI T102 The associated encoding eliminates the need to input the complete device identification code of the detection module 100 and / or infusion module 102. Different encoding mappings correspond to different signal strength thresholds (RSSI). T100 and / or RSSI T102 When the patient inputs a code in program module 101, the corresponding signal strength threshold RSSI is retrieved from the signal strength threshold list profile. T100 and / or RSSI T102Furthermore, the corresponding program module 101 identifies the 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 this invention, the aforementioned signal strength threshold RSSI T100 and / or RSSI T102 The associated encoding can be a single character, such as any Arabic numeral from 0 to 9, a Greek numeral, any letter from AZ, or any punctuation mark; there are no restrictions. In an exemplary description, the Arabic numeral 5 represents a signal strength threshold RSSI. T5 The maximum distance at which the program module 101 corresponding to this signal strength threshold establishes a wireless communication connection with the detection module 100 and / or the infusion module 102 is 0.5m. The Arabic numeral 3 represents another signal strength threshold, RSSI. T3 The maximum distance at which the program module 101 corresponding to this signal strength threshold establishes a wireless communication connection with the detection module 100 and / or the infusion module 102 is 0.3m. The letter A represents another signal strength threshold, RSSI. TA The maximum distance at which the program module 101 corresponding to the signal strength threshold establishes a wireless communication connection with the detection module 100 and / or the infusion module 102 is 0.05m. The above characters and their corresponding maximum distances are for illustrative purposes only.

[0101] In other embodiments of this invention, the aforementioned signal strength threshold RSSI T100 and / or RSSI T102 The associated code can be at least two characters and can consist of any Arabic numerals, Greek numerals, letters, or punctuation marks, or a combination thereof; no restrictions are placed on this. In an exemplary description, the Arabic numeral 25 represents a signal strength threshold RSSI. T25 The maximum distance at which the program module 101 corresponding to this signal strength threshold establishes a wireless communication connection with the detection module 100 and / or the infusion module 102 is 0.25m. The Arabic numeral 21 represents another signal strength threshold, RSSI. T21 The maximum distance at which the program module 101 corresponding to this signal strength threshold establishes a wireless communication connection with the detection module 100 and / or the infusion module 102 is 0.21m. The letter 1A represents another signal strength threshold RSSI. T1A The maximum distance at which the program module 101 corresponding to the signal strength threshold establishes a wireless communication connection with the detection module 100 and / or the infusion module 102 is 0.05m.

[0102] In some embodiments of this invention, the aforementioned signal strength threshold RSSI T100 and / or RSSI T102 The associated code can be a symbol at any position in the device identifier code; it can be a continuous symbol code or a discontinuous, skipped symbol code, without limitation. In an exemplary description, the code 1**2******** represents a signal strength threshold RSSI. T12 The asterisk (*) indicates the device identification code, which is the signal strength threshold RSSI. T12 The corresponding codes are located in the first and fourth positions of the device identification code. The patient only needs to input "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 this invention, the aforementioned signal strength threshold RSSI T100 and / or RSSI T102 The associated codes are printed separately on the detection module 100 and / or the infusion module 102 or on the packaging.

[0104] After being powered on, the detection module 100 and / or infusion module 102 transmit broadcast signals at normal power, referred to here as the first power. In some existing technologies, to facilitate the establishment of wireless communication connections by patients, the first power is usually set relatively high to ensure the effective range of the broadcast signal for the program module 101 to search and identify. Transmitting broadcast signals at the first power for an extended period results in excessive power consumption for the detection module 100 and / or infusion module 102, affecting their lifespan.

[0105] Reference Figure 5d In some embodiments of this utility model, in order to save power consumption and extend the service life of the detection module 100 and / or the infusion module 102, the detection module 100 and / or the infusion module 102 can reduce the broadcast signal transmission power during the broadcast signal transmission period 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 one-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 As before, program module 101 just detected that the broadcast signal strength reached the preset signal strength threshold RSSI. T100 and / or RSSI T102At this time, 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 transmitting a broadcast signal at the first power, 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 is 0.5m. When transmitting a broadcast signal at the second power, if the preset signal strength threshold RSSI is maintained... T100 and / or RSSI T102 Without change, 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 0.3m or 0.1m. 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 its signal transmission power to maintain a long-distance wireless communication connection with the program module 101 at a 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 0-10m, which is convenient for the patient's daily use.

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

[0107] Upon power-up, the detection module 100 and / or infusion module 102 transmit a broadcast signal at the first power. During the establishment of a wireless communication connection between the patient operation program module and the detection module 100 and / or infusion module 102, due to improper operation or interference from other factors, the wireless communication connection between the program module 101 and the detection module 100 and / or infusion module 102 cannot be established in a timely manner. This increases the power consumption of the detection module 100 and / or infusion module 102 and reduces the service life of the detection module 100 and / or infusion module 102.

[0108] Regarding the above issues, refer to Figure 5e In some embodiments of this utility model, a time threshold is set in the detection module 100 and / or the infusion module 102. After power-on, a broadcast signal is sent with a first parameter, and timing begins. 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 decrease the broadcast signal transmission parameter and send the broadcast signal with a second parameter. In embodiments of this utility model, "parameter" can correspond to power or time interval.

[0109] When the "parameter" corresponds to the power, as mentioned above, the second power is less than the first power. For example, the second power is one-half or one-third of the first power. In this case, the patient needs to move the operating 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 this invention, the preset time threshold for the detection module 100 and / or infusion module 102 to send a broadcast signal at a first power after being powered on 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.

[0111] In other embodiments of this utility model, 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 transmission time interval of 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, and 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 transmission time interval of the broadcast signal is increased, for example, before and after the preset time threshold, the transmission time interval between two adjacent broadcast signals increases from 0.1 seconds to 10 seconds. Increasing the transmission time interval of the broadcast signal reduces the number of broadcast signals transmitted per unit time, 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. Longer broadcast signal transmission intervals save more power, but also increase the waiting time for patients when establishing wireless communication connections. Choosing an appropriate broadcast signal transmission interval can reduce power consumption while also meeting the user experience needs of patients.

[0112] In some embodiments of this utility model, in order to further reduce the power consumption of the detection module 100 and / or the infusion module 102, while reducing the transmission power of the broadcast signal, the transmission time interval of the broadcast signal can also be increased.

[0113] In some embodiments of this utility model, if the patient cannot establish a wireless communication connection between the program module 101 and the detection module 100 and / or the infusion module 102 in a timely manner, the patient's position may change when establishing a wireless communication connection in subsequent operations. The patient's own detection module 100 and / or infusion module 102 may become closer to the detection modules 100 and / or infusion modules 102 of other patients, increasing the risk of establishing an incorrect wireless communication connection. This is detrimental to the patient's operation of establishing a wireless communication connection.

[0114] Regarding the above issues, refer to Figure 5f In some embodiments of this utility model, a time threshold can be set in the detection module 100 and / or the infusion module 102, and timing can begin after power-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 where the program module 101 inputs the device identification code of the detection module 100 and / or the infusion module 102 to establish a wireless communication connection. If the patient continues to operate to establish a wireless communication connection, they can continue to operate the program module 101 to search for broadcast signals, or they can 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. This reduces the possibility that the program module 101 connects to the wrong detection module 100 and / or the infusion module 102.

[0115] In other embodiments of this utility model, a time threshold can 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 wireless communication connection is established. 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 can 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. If the patient continues to establish a wireless communication connection, they can continue to operate the program module 101 to search for broadcast signals, or they can 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 that the program module 101 connects to the wrong detection module 100 and / or the infusion module 102.

[0116] In some embodiments of this invention, the preset time threshold for the device identification code 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 this invention, when the operating program module 101 searches for broadcast signals in certain situations, the patient may identify that the signal strength of multiple broadcast signals is not less than a preset signal strength threshold RSSI. T100 and / or RSSI T102 In this situation, program module 101 will be unable to select a broadcast signal to establish a wireless communication connection, and will promptly notify the patient that there are multiple connectable broadcast signals in the vicinity, requiring a change of operating location or a re-establishment of the wireless communication connection, until program module 101 identifies only one broadcast signal whose signal strength is not less than the preset signal strength threshold RSSI. T100 and / or RSSI T102Alternatively, the program module 101 may prompt the patient to enter the device identification code of the detection module 100 and / or infusion module 102, thereby establishing a wireless communication connection between the program module 101 and the patient's own detection module 100 and / or infusion module 102.

[0118] In some embodiments of this invention, to avoid prolonged waiting by the patient during the establishment of a wireless communication connection, the program module 101 starts timing when it begins searching for and identifying broadcast signals. For example, if the program module 101 fails to 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 the preset signal strength threshold, within 5 seconds of the program module 101 starting to search for and identify broadcast signals, the program module 101 will prompt the patient to re-establish the wireless communication connection or change the operation location. If, within the next 20 seconds, the program module 101 still fails to 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 for illustrative purposes only.

[0119] In some embodiments of this utility model, considering that the program module 101 of the signal receiving end may have different recognition of broadcast signals of the same signal strength due to individual state differences, for example, after the program module 101 leaves the factory, its hardware gradually ages over time, and its sensitivity to signal strength recognition gradually decreases. Since the program module 101 is generally a reusable device, its absolute strength recognition of broadcast signals may change during use. When a 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 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 preset signal strength threshold RSSI. T100 and / or RSSI T102 A comparison is made to determine whether a wireless communication connection should be established. The corrected broadcast signal strength ensures that the maximum distance between the program module 101 and the detection module 100 and / or the infusion module 102 does not change significantly when the patient is establishing a wireless communication connection. For example, the range of change is between -0.05m and 0.05m, which can minimize the impact on the patient's operating habits.

[0120] In some embodiments of this utility model, 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 longer periods of time, the signal correction coefficient can be adjusted over time.

[0121] In some embodiments of this 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 This diagram illustrates the operation pairing and communication connection establishment in different embodiments of the present invention.

[0123] Reference Figure 6a In some embodiments of this invention, the program module 101, detection module 100, and infusion module 102 can establish communication connections with each other. Each of these modules can act as a signal source device, transmitting broadcast signals for other modules to search for and pair with to establish communication connections. The signal source device can transmit broadcast signals at low power, limiting the effective range of the broadcast signal. For example, the effective range of the broadcast signal may be 0–0.5 m. If the distance between other patients' devices seeking to establish a communication connection and the signal source device exceeds 0.5 m, they cannot detect the broadcast signal of the signal source device and therefore cannot pair with it 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 pair with the patient's own device instead of other patients' devices to establish a communication connection. Specific details of this solution will be described below.

[0124] In some embodiments of this utility model, the three devices—program module 101, detection module 100, and infusion module 102—can be arbitrarily paired to establish two sets of communication connections, thus satisfying the communication link integrity of the blood glucose management system. That is, any two devices among program module 101, detection module 100, and infusion module 102 serve as signal source devices, and the remaining device serves as the device to establish a communication connection. The device to establish a communication connection is paired with the two signal source devices to establish a communication connection. For example, program module 101 and infusion module 102 serve as signal source devices, and detection module 100 serves as the device to establish a communication connection. Program module 101 is paired with detection module 100, and detection module 100 is paired with infusion module 102 to establish a communication connection. Program module 101 and detection module 100, and detection module 100 and infusion module 102 can directly transmit data, and program module 101 and infusion module 102 can indirectly transmit data through detection module 100.

[0125] In some embodiments of this utility model, the three devices, program module 101, detection module 100, and infusion module 102, can also be paired up to establish three sets of communication connections to increase the communication redundancy of the blood glucose management system. When any one set of communication connections is disconnected for any reason, the remaining two sets 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, program module 101, detection module 100, and infusion module 102 all act as signal source devices to send broadcast signals and as devices to be established to search for broadcast signals. For example, program module 101 and detection module 100, detection module 100 and infusion module 102, and infusion module 102 and program module 101 can be paired up to establish communication connections respectively.

[0126] Reference Figure 6b In some embodiments of this utility model, in most usage scenarios, when a patient operates a pairing device to establish communication, they typically keep the device to be established close to them, for example, within the range of their left and right hands. The radius of this range is generally 0-0.5m, for example, 0.05m or 0.1m. Simultaneously, the patient is relatively far from other patients, for example, more than 0.5m. Therefore, regardless of which device the patient uses as the broadcast signal source, the signal source device is close to the patient's own device and far from other patients' devices. When the patient's own device is within the effective range of the broadcast signal source device, while other patients' devices are outside its effective range, the patient's own device can directly pair with the broadcast signal source device to establish a communication connection. There is no need to worry about pairing with other patients' broadcast signal source devices, nor is there any need to worry about the patient's own broadcast signal source device being paired with other patients' devices, thus ensuring the reliability of the patient's own device establishing a wireless communication connection.

[0127] In some embodiments of this invention, the infusion module 102 is a broadcast signal source device, and the detection module 100 and program module 101 are devices to be established for communication connection. The infusion module 102 sends a broadcast signal upon power-up. This broadcast signal can be a low-power Bluetooth signal with an effective range of 0-0.5m, significantly shorter than the 0-20m effective communication distance of conventional Bluetooth signals. When a patient establishes a pairing communication connection, they first power on the infusion module 102a, then hold their own detection module 100a and program module 101a close to the infusion module 102a. When the detection module 100a and program module 101a enter the effective range of the broadcast signal of the infusion module 102a, they can detect the broadcast signal. Meanwhile, detection modules 100b and program modules 101b held by other patients are outside the effective broadcast range of the infusion module 102a and cannot detect the broadcast signal. Similarly, if a patient's own detection module 100a and program module 101a are outside the effective range of the broadcast signal from another patient's infusion module 102b, they will also be unable to detect the broadcast signal sent by the other patient's infusion module 102b. In this scenario, when the patient's detection module 100a and program module 101a detect the broadcast signal while approaching the infusion module 102a, they can confirm that the broadcast signal source device is their own infusion module 102a with which they wish to establish a communication connection. They will not need to worry about establishing an incorrect communication connection, and the patient will not need to input the device code of the infusion module 102a into their detection module 100a and program module 101a. They 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 blood glucose management system's communication connection.

[0128] In the above embodiments, 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 establish a communication connection. In some 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 establish a communication connection. In still some 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 establish a communication connection.

[0129] In other embodiments of this utility model, the broadcast signal may also be a near-field communication signal, an infrared signal, a radio frequency signal, an optical signal, or an audio signal, etc., and is not limited thereto.

[0130] In a preferred embodiment of this invention, program module 101 serves as a broadcast signal source device, while infusion module 102 and detection module 100 serve as devices to be paired and establish communication connections. Infusion module 102 and program module 101, and detection module 100 and program module 101, are respectively paired and establish communication connections. Program module 101 can control infusion module 102 to perform drug infusion while simultaneously controlling detection module 100 to perform blood glucose detection. Furthermore, program module 101 can also serve as a data processing center for drug infusion data and blood glucose detection data, optimizing drug infusion data through blood glucose detection data, or optimizing blood glucose detection data through drug infusion data feedback, thereby improving the therapeutic effect of the blood glucose management system. In this preferred embodiment, program module 101 serves as a broadcast signal source device. When the patient operates detection module 100 and infusion module 102 to approach program module 101, and the detection module 100 and infusion module 102 detect the broadcast signal, the signal source device is considered to be the patient's program module 101. The patient does not need to input the device code of program module 101 to establish a pairing and communication connection.

[0131] Reference Figure 6cIn some embodiments of this invention, patients may use multiple infusion modules 102, detection modules 100, or program modules 101, such as detection modules 100 and 200. Patients can attach one detection module 100 to their arm and another detection module 200 to their waist to detect blood glucose signals from different parts of their body. After receiving the two blood glucose signals, program module 101 can optimize the algorithm to obtain the final blood glucose signal, thereby improving the accuracy of blood glucose detection. However, when detection modules 100 and 200 are used as signal source devices simultaneously, if the distance between them is less than the effective range of the broadcast signal, they can search for each other's broadcast signals and pair up to establish a communication connection. This may occupy the communication channels of detection modules 100 and 200, causing communication congestion. Detection module 100 or 200 may then be unable to 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 issues, when the infusion module 102, detection module 100, and program module 101 act as signal source devices, their broadcast signal encoding formats are different. Therefore, although the infusion module 102, detection module 100, and program module 101 can all send low-power Bluetooth signals, the device to be established with a communication connection can distinguish whether the signal source device is the infusion module 102, detection module 100, or program module 101 based on the broadcast signal encoding format it has searched for. If the signal source device corresponding to the broadcast signal encoding format it has searched for is the same type as the device to be established with a communication connection, the device to be established with a communication connection can refuse to pair and establish a communication connection to avoid establishing pairing communication connections between the same devices, which would cause communication channel congestion and ensure the reliability of the blood glucose management system's communication connection.

[0132] In the above embodiments, when detection modules 100 and 200 function as signal source devices, they simultaneously have signal transmission and signal reception functions, enabling bidirectional communication with other devices. In other embodiments of this invention, detection modules 100 and 200, as signal source devices, only have signal transmission functions and do not search for or receive broadcast signals from other signal source devices. However, when a device seeking to establish a communication connection detects a broadcast signal sent by detection module 100 or detection module 200, it can still pair with detection module 100 or detection module 200 to establish a communication connection. Therefore, detection modules 100 and 200, as signal source devices, will not pair with each other to establish a communication connection, avoiding communication channel congestion and ensuring the reliability of the blood glucose management system's communication connection.

[0133] In some embodiments of this utility model, when detection module 100 and detection module 200 are both used as signal source devices, if the number of communication channels of detection module 100 and detection module 200 is sufficient, and when 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, as signal source devices, can also search for each other's broadcast signals. Detection module 100 and detection module 200 can directly pair up and establish a communication connection. At the same time, when the patient operates their own infusion module 102 and program module 101 close to detection module 100 and detection module 200, the broadcast signals of detection module 100 and detection module 200 can be searched by the patient's own infusion module 102 and program module 101. Detection module 100 also pairs up and establishes a communication connection with infusion module 102 and program module 101 respectively. At the same time, detection module 200 also pairs up and establishes a communication connection with infusion module 102 and program module 101 respectively. That is, as long as the number of communication channels of the signal source device is sufficient, it can pair up and establish a communication connection with any device. The detection module 100 and detection module 200 maintain a communication connection, providing communication link redundancy for the blood glucose management system and enhancing the robustness of system data transmission. Even if the infusion module 102 or program module 101 loses communication with one of the detection modules 100 and 200 for any reason, the infusion module 102 or program module 101 can still indirectly transmit data through the communication link with the other detection module, ensuring the reliability of the communication connection of the blood glucose management system.

[0134] In some embodiments of this utility model, in the blood glucose management system, the patient may also use multiple infusion modules 102 or program modules 101 as signal source devices. The method of establishing communication connection by close pairing of multiple infusion modules 102 or program modules 101 is the same as that of multiple detection modules 100, and will not be described again here.

[0135] In some embodiments of this invention, in the blood glucose management system, the patient may also use the detection module 100 and the program module 101 simultaneously as signal source devices, and the infusion module 102 as a device to be paired to establish a communication connection. The infusion module 102 is paired with both the detection module 100 and the program module 101 to establish a communication connection. When the patient establishes a communication connection, if the distance between the detection module 100 and the program module 101 is far enough that 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 bring the infusion module 102 close to both the detection module 100 and the program module 101 in sequence, and the infusion module 102 will then pair with both the detection module 100 and the program module 101 to establish a communication connection. When a patient establishes 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 brings 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 this utility model, when the detection module 100 and the program module 101 both function as signal source devices, and the infusion module 102 functions as a device to be paired and establish a 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 function as a device to be paired and establish a communication connection. When the number of communication channels of the detection module 100 or the program module 101 is sufficient, and the detection module 100 or the program module 101 detects a broadcast signal, it can pair with the signal source device of that 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, and the detection module 100 or the program module 101 detects a broadcast signal, it can refuse to pair with the signal source device of that broadcast signal to establish a communication connection. That is, signal source devices are not allowed to pair and establish communication connections. 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 this invention, in the blood glucose management system, the patient may use both the detection module 100 and the infusion module 102 as signal source devices, and the program module 101 as a device to be paired and establish a communication connection. Alternatively, the patient may use both the program module 101 and the infusion module 102 as signal source devices, and the detection module 100 as a device to be paired and establish a communication connection. The specific pairing and communication connection establishment method is the same as described above and will not be repeated here.

[0138] In a preferred embodiment of this invention, the patient uses both the detection module 100 and the infusion module 102 as signal source devices, and the program module 101 as a device to be paired and establish a communication connection. During the pairing and communication connection establishment process, the patient holds the program module 101 close to both the detection module 100 and the infusion module 102. When the program module 101 detects a broadcast signal, it can be assumed that the broadcast signal was emitted by the patient's own detection module 100 or infusion module 102. The patient does not need to input the device code of the detection module 100 or infusion module 102 to 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 establish a communication connection either by pairing or by not pairing.

[0139] Reference Figure 6d In some embodiments of this utility model, when multiple different broadcast signal source devices exist, such as the infusion module 102 and the program module 101 both capable of transmitting low-power broadcast signals, the effective range of the broadcast signal is relatively short, and 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 detection module 100a to approach the infusion module 102, entering the effective range of the broadcast signal of the infusion module 102, and pair with the infusion module 102 to establish a wireless communication connection. Then, the patient can operate the detection module 100a to approach the program module 101, entering the effective range of the broadcast signal 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 detection module 100a to approach the program module 101, entering the effective range of the broadcast signal of the program module 101, and pair with the program module 101 to establish a wireless communication connection. Then, the patient can operate the detection module 100a to approach the infusion module 102, entering the effective range of the broadcast signal of the infusion module 102, and pair with the infusion module 102 to establish a wireless communication connection. During the pairing process described above, the detection modules 100b of other patients do not enter the effective range of the corresponding broadcast signals. Similarly, the detection modules 100a of other patients will not enter the effective range of the broadcast signals of other patients. Therefore, the detection modules 100a of other patients will only search for the broadcast signals emitted by their own infusion modules 102 and program modules 101. The broadcast signals emitted by the infusion modules 102 and program modules 101 of other patients will also only be searched by their own detection modules 100a. The detection modules 100a can directly pair with the signal source device to establish a communication connection without having to input the device codes of the infusion modules 102 and program modules 101, saving time and effort, and ensuring the reliability of the communication connection of the patient's blood glucose management system.

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

[0141] Reference Figure 6e In some embodiments of this utility model, when the effective range of the broadcast signals of the infusion module 102 and the program module 101 overlaps, when the patient operates the detection module 100a to approach the infusion module 102 and the program module 101, it 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 simultaneously pair the detection module 100a with the infusion module 102 and the detection module 100a with the program module 101 to establish a communication connection. During the pairing process described above, 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 a patient will not enter the effective range of the broadcast signals of other patients. Therefore, the detection module 100a of a 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 needing to input the device codes of the infusion module 102 and program module 101, thus ensuring the reliability of the communication connection of the patient's blood glucose management system.

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

[0143] Reference Figure 6fIn some embodiments of this invention, even with the use of low-power Bluetooth technology to reduce the effective range of the broadcast signal, in certain usage scenarios, such as hospitals, where patients are relatively close together and the distance between the detection modules 100, program modules 101, and infusion modules 102 of each patient is short, incorrect broadcast signals may still be detected during pairing and communication connection establishment, leading to incorrect device pairing. For example, a patient's infusion module 102a sends a broadcast signal after being powered on, acting as a signal source device. Simultaneously, another patient also powers on their infusion module 102b and sends a broadcast signal, acting as another signal source device. These two patients are close together, with the distance between infusion modules 102a and 102b possibly only 0.3m. This distance causes the effective range of the broadcast signals of the two infusion modules 102a / 102b to overlap. When a patient operates their program module 101a to approach their infusion module 102a in an attempt to pair and establish a communication connection, they may accidentally enter the other patient's field of vision. If the broadcast signal of infusion module 102b is within the effective range, the program module 101a will recognize the broadcast signals of two infusion modules 102a / 102b. At this time, the patient cannot distinguish which broadcast signal comes from his / her own infusion module. At this time, the patient can still input the device code (SN) of infusion module 102a into program module 101a to pair and establish a communication connection between infusion module 102a and program module 101a, or input the device code of infusion module 102a into detection module 100a to pair and establish a communication connection between infusion module 102a and detection module 100a.

[0144] In some embodiments of this invention, although the detection module 100, program module 101, or infusion module 102 transmits broadcast signals at low power while acting as a signal source device, after formally pairing and establishing a communication connection with the device to be paired, the signal source device switches to transmitting communication signals. These communication signals are used to achieve end-to-end data transmission. At this point, the transmission power of the communication signal needs to be increased to expand its effective range, for example, increasing it to 0-10m, so that the patient or their caregiver can remotely control the program module 101. Of course, if the patient does not need to remotely control the program module 101, the transmission power of the communication signal from the signal source device can still be kept low to reduce power consumption.

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

[0146] In other embodiments of this utility model, the communication signal may also be a near-field communication signal, an infrared signal, a radio frequency signal, an optical signal, or an audio signal, etc., and is not limited thereto.

[0147] In some embodiments of this utility model, in order to further ensure the reliability of the wireless communication connection established between the program module 101, the detection module 100, and the infusion module 102, the patient's confirmation instruction is also required when the program module 101, the detection module 100, and the infusion module 102 establish a wireless communication connection.

[0148] In some embodiments of this invention, although the signal source device transmits broadcast signals using low-power Bluetooth, the effective range of the broadcast signal is 0-0.5m. This effective range provides sufficient space for the patient to operate and establish a communication connection. To further ensure the reliability of the pairing and communication connection and avoid establishing incorrect communication connections, the patient can directly contact the signal source device with the device to be paired and established during the pairing and communication connection process. At this time, the effective range of the broadcast signal of the signal source device can be adjusted to be even smaller, such as 5cm or 3cm. The smaller the effective range of the broadcast signal, the more likely the patient is to establish incorrect communication connections, and the more reliable the communication of the blood glucose management system is improved.

[0149] In summary, this utility model discloses a blood glucose management system. When a patient establishes a communication connection, at least one device among the detection module, infusion module, and program module acts as a signal source device, sending a low-power broadcast signal. At least one device acts as a device to be paired for establishing a communication connection. The patient operates the device to be paired to approach the signal source device. When the device to be paired enters the effective range of the broadcast signal, it can detect the broadcast signal and pair with the signal source device to establish a communication connection. Since the effective range of the broadcast signal is relatively small, generally smaller than the conventional distance between the two devices, it avoids the device to be paired to detect the wrong broadcast signal and establish an incorrect communication connection. When the device to be paired detects the broadcast signal, it can recognize the signal source device as the patient's own device. The patient does not need to input a device code; the device to be paired and the signal source device can automatically establish a communication connection, saving time and effort and improving the patient's user experience.
