Description

A method for finding lost devices in a diabetes management system Technical Field

[0001] The present invention mainly relates to the field of medical devices, and in particular to a method for finding lost devices and a method for preventing device loss applied to a diabetes management system. Background Art

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

[0003] Diabetic patients need to monitor their blood sugar levels before injecting insulin. Currently, most monitoring methods use internal blood sugar monitoring devices to continuously monitor blood sugar levels. These devices use disposable transcutaneous sensors inserted into the skin to measure blood sugar concentrations in the interstitial fluid and transmit this data in real time to an external device via a transmitter for easy viewing by the patient. This monitoring method is called continuous glucose monitoring (CGM).

[0004] Doctors will give different recommendations based on the severity of the patient's illness and their individual health conditions. For example, patients with very mild symptoms may only need to regularly measure a small amount of fingertip blood for testing. General diabetics can achieve self-monitoring and management of their blood sugar through continuous blood glucose monitoring. For more severe diabetics, a doctor's intervention is required to adopt a targeted insulin infusion plan to restore the diabetic's blood sugar level to a relatively stable state. At the same time, personalized diet and exercise plans are provided to enable patients to achieve self-monitoring and management of their blood sugar. The device for continuous blood glucose monitoring is generally a CGM, and the device for drug infusion is generally an insulin pump. Because inaccuracies in insulin infusion can pose risks of high and low blood sugar to patients, patients must first be evaluated by a doctor before using an insulin pump to confirm that their physical condition is suitable for the use of an insulin pump, and at the same time, they must follow the insulin infusion plan prescribed by the doctor.

[0005] Currently, when users manage their diabetes through CGM and / or insulin pumps, they need personal management devices or secondary management devices for management. Since some patients require guardians to manage them at the same time, patients and guardians may need to use personal management devices or secondary management devices at the same time. In addition, in order to manage patients more comprehensively, patients or guardians may prepare multiple personal management devices or secondary management devices at the same time to prevent one of them from running out of power or being occupied by other functions and unable to provide comprehensive management in real time. However, when the number of devices used in the system increases, the loss of devices may occur due to various reasons.

[0006] Therefore, the prior art urgently needs a method for finding lost devices and a method for preventing device loss that can be applied to a diabetes management system.

[0007] Summary of the Invention

[0008] An embodiment of the present invention discloses a method for finding a lost device applied to a diabetes management system. The diabetes management system includes at least one wearable medical device; at least one personal management device and a secondary management device. At least one of the personal management device and the secondary management device can be used to control the wearable medical device, and the personal management device and the secondary management device are communicatively connected. When one of the personal management device and the secondary management device is determined to be lost, the user can easily find the lost device by searching for the lost device through the other of the personal management device and the secondary management device.

[0009] The present invention discloses a method for finding a lost device applied to a diabetes management system. The diabetes management system includes at least one wearable medical device; at least one personal management device and a secondary management device. At least one of the personal management device and the secondary management device can be used to control the wearable medical device, and the personal management device and the secondary management device are communicatively connected. When one of the personal management device and the secondary management device is determined to be lost, the lost device is found through the other of the personal management device and the secondary management device.

[0010] According to one aspect of the present invention, the method further includes confirming a communication connection status between the personal management device and the secondary management device.

[0011] According to one aspect of the present invention, when the personal management device and the secondary management device are in a communication connection state, an instruction is sent to the lost device via the surviving device.

[0012] According to one aspect of the present invention, both the personal management device and the secondary management device are provided with a locator. When the personal management device and the secondary management device are in a communication connection state, they send their own location information to each other and store the location information of the other party.

[0013] According to one aspect of the present invention, when the personal management device and the secondary management device are in a disconnected state, the lost device is found based on the most recent location information of the lost device stored on the surviving device.

[0014] According to one aspect of the present invention, the surviving device is gradually brought closer to its most recent location and a communication connection request is sent to the lost device. When the personal management device and the secondary management device are within the communication connection distance range, the personal management device and the secondary management device establish a communication connection.

[0015] According to one aspect of the present invention, after the personal management device and the secondary management device establish a communication connection, the surviving device automatically sends an instruction to the lost device.

[0016] According to one aspect of the present invention, after receiving the instruction, the lost device sends a prompt to indicate the specific location of the lost device.

[0017] According to one aspect of the present invention, the prompt is a sound prompt, a vibration prompt, a color prompt or a combination of one or more.

[0018] According to one aspect of the present invention, when the personal management device or the secondary management device does not receive the location information of the other party within a predetermined time interval, the personal management device and / or the secondary management device issues an alarm.

[0019] According to one aspect of the present invention, the personal management device and the secondary management device periodically send their own location information to each other when they are in a communication connection state, and the predetermined time interval is an integer multiple of the time interval for the personal management device and the secondary management device to periodically send their own location information to each other.

[0020] According to one aspect of the present invention, the setting of the time interval for the personal management device and the secondary management device to periodically send their own location information to each other is associated with the communication mode between the personal management device and the secondary management device.

[0021] According to one aspect of the present invention, the communication mode between the personal management device and the secondary management device includes at least one or more of Bluetooth, mobile cellular, WiFi, and the Internet.

[0022] According to one aspect of the present invention, the type of alarm is a combination of one or more of a sound alarm, a vibration alarm, and an interface text alarm.

[0023] According to one aspect of the present invention, after receiving the alert, the user further checks the location or communication connection status of the personal management device and the secondary management device.

[0024] According to one aspect of the present invention, when the personal management device or the secondary management device loses communication connection, the personal management device and / or the secondary management device issues an alarm.

[0025] The present invention also discloses a method for preventing device loss applied to a diabetes management system, wherein the diabetes management system includes at least one wearable medical device; at least one personal management device and a secondary management device, and at least one of the personal management device and the secondary management device can be used to control the wearable medical device; both the personal management device and the secondary management device are provided with a locator, and when the personal management device and the secondary management device are in a connected state, they send their own location information to each other and store the location information of the other party at the same time; when the personal management device or the secondary management device does not receive the location information of the other party within a predetermined time interval or the personal management device and the secondary management device disconnect the communication connection, the personal management device and / or the secondary management device issues an alarm.

[0026] According to one aspect of the present invention, the personal management device and the secondary management device periodically send their own location information to each other when they are in a communication connection state, and the predetermined time is an integer multiple of the time interval between the personal management device and the secondary management device periodically sending their own location information to each other.

[0027] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0028] The diabetes management system disclosed in the present invention includes at least one wearable medical device; at least one personal management device and a secondary management device, at least one of the personal management device and the secondary management device can be used to control the wearable medical device, and the personal management device and the secondary management device are communicatively connected; when one of the personal management device and the secondary management device is determined to be lost, the user can easily retrieve the lost device by searching for the lost device through the other of the personal management device and the secondary management device.

[0029] Furthermore, when the personal management device and the secondary management device are in a connected state, an instruction is sent to the lost device through the non-lost device. After receiving the instruction, the lost device issues a prompt to indicate the specific location of the lost device, making it easier for the user to quickly find the lost device.

[0030] Furthermore, both the personal management device and the secondary management device are provided with a locator. When the personal management device and the secondary management device are in a communication connection state, they send their own location information to each other and store the location information of each other. When the personal management device and the secondary management device are in an unconnected state, the user can view the most recent location information of the lost device on the non-lost device. On the one hand, the user can directly quickly find the lost device based on the most recent location information; on the other hand, the user can gradually move the non-lost device closer to the most recent location and send a communication connection request to the lost device. When the personal management device and the secondary management device are within the communication connection distance range, the personal management device and the secondary management device switch from an unconnected state to a connected state. At this time, the non-lost device automatically sends a command to the lost device. After receiving the command, the lost device issues a prompt to indicate the specific location of the lost device, making it easier for the user to find the lost device more quickly.

[0031] Furthermore, when the personal management device or the secondary management device does not receive the other party's location information within a predetermined time, the personal management device and / or the secondary management device issues an alarm to remind the user that the device may be lost. After receiving the alarm, the user further checks the location or connection status of the personal management device and the secondary management device to prevent the device from being lost.

[0032] Furthermore, when the personal management device and the secondary management device are disconnected, the personal management device and / or the secondary management device issues an alarm to remind the user that the connection between the personal management device and / or the secondary management device has been disconnected, prompting the user to re-establish the communication connection as soon as possible to prevent the device from being lost.

[0033] Furthermore, the predetermined time interval in which the personal management device and / or the secondary management device does not receive the location information of the other party within the predetermined time interval is an integer multiple of the time interval for periodically sending the location information of the personal management device and the secondary management device to the other party when they are in a connected state. When the time interval for periodically sending location information of the two is relatively long, the multiple is relatively small; when the time interval for periodically sending location information of the two is relatively short, the multiple is relatively large. On the one hand, it can avoid triggering unnecessary alarms when the personal management device and / or the secondary management device fails to send its own location information normally due to random or short-term errors, and at the same time avoid increasing the difficulty of finding the lost device due to the disconnection of the personal management device and the secondary management device.

[0034] Furthermore, the personal management device and the secondary management device include one or more dedicated handheld devices, smart phones, and personal computers. The users of the personal management device and the secondary management device can be patients and / or guardians, and the devices used can be one or more. The personal management device or secondary management device used can be the same device or different devices, which makes it convenient for users to choose according to different needs and improves the user experience.

[0047] FIG1 is a schematic diagram of a diabetes management system according to an embodiment of the present invention.

[0048] In some embodiments of the present invention, the diabetes management system 10 includes at least one wearable medical device 11 , a personal management device 12 , and a secondary management device 13 .

[0049] The wearable medical device 11 includes a blood glucose monitor (CGM) and / or an insulin pump. The CGM device, used by the patient, is used to monitor the patient's blood glucose level in real time and is installed on the patient via an auxiliary mounting device. The CGM device includes an implantable sensor connected to a transmitter. The transmitter also includes a memory, a processor, a communication interface, etc. The transmitter is used to transmit blood glucose data monitored by the CGM device, as well as an identifier of the CGM device. The insulin pump used by the patient includes the infusion structure and control structure necessary for insulin infusion, such as a drug storage cartridge, a drive structure, an infusion line and infusion needle, a power supply, a circuit board, etc. The control structure includes a memory, a processor, a communication interface, etc. The infusion structure is used to infuse the patient's required insulin into the patient's body, and the control structure is used to receive insulin infusion instructions and transmit information such as the insulin infusion status and the insulin device identifier.

[0050] At least one of the personal management device 12 and the secondary management device 13 is used to control the operation of the medical device 11 and includes a memory, a processor, a communication interface, a display, a user interface, etc. The memory stores programming instructions, and the processor can execute the programming instructions in the memory. When the personal management device 12 and the secondary management device 13 are used to control the operation of the medical device 11 simultaneously, the blood glucose monitoring device is attached to the user's skin surface to obtain blood glucose concentration information in the user's body and transmit the blood glucose concentration information to the personal management device 12 and the secondary management device 13. After receiving the blood glucose concentration information, the personal management device 12 and the secondary management device 13 analyze and organize it, and ultimately display it in an intuitive manner on the display screens of the personal management device 12 and the secondary management device 13. The insulin pump infuses insulin according to the infusion instructions received from the personal management device 12 and / or the secondary management device 13, and at the same time feeds back the infusion status to the personal management device 12 and the secondary management device 13. After receiving the insulin infusion information, the personal management device 12 and the secondary management device 13 analyze and organize it, and finally display it in an intuitive manner on the display screens of the personal management device 12 and the secondary management device 13.

[0051] When one of the personal management device 12 and the secondary management device 13 is used to control the operation of the medical device 11, the blood glucose monitoring device and the insulin pump transmit blood glucose information and insulin infusion information to the device controlling the medical device 11, such as the personal management device 12, in the manner described above. The personal management device displays the blood glucose information and insulin infusion information in an intuitive manner, and the secondary management device 13 can also view and display the blood glucose information and insulin infusion information by communicating with the personal management device 12. Similarly, the blood glucose monitoring device and the insulin pump transmit blood glucose information and insulin infusion information to the secondary management device 13 in the manner described above. The secondary management device 13 displays the blood glucose information and insulin infusion information in an intuitive manner, and the personal management device 12 can also view and display the blood glucose information and insulin infusion information by communicating with the secondary management device 13.

[0052] The personal management device 12 and / or the secondary management device 13 include a dedicated handheld device, a smart phone capable of downloading a dedicated APP, a personal computer capable of logging into a dedicated website, a tablet, etc.

[0053] It should be noted that, in the embodiments of the present invention, the personal management device 12 and the secondary management device 13 can be the same device or different devices, and can have the same functions and roles. Therefore, in the embodiments of the present invention, the personal management device 12 and the secondary management device 13 are not divided into primary and secondary functions, but are named differently to distinguish between the two different devices. In some embodiments of the present invention, the wearable medical device 11 is wirelessly connected to the personal management device 12 and / or the secondary management device 13 via Bluetooth, mobile cellular, Wi-Fi or the Internet. In one embodiment of the present invention, the wearable medical device 11 is wirelessly connected to the personal management device 12 and / or the secondary management device 13 via Bluetooth, which can save power consumption of the wearable medical device 11 and extend its service life.

[0054] In some embodiments of the present invention, the personal management device 12 can establish a wireless communication connection with the secondary management device 13 via Bluetooth, Wi-Fi or the Internet, or establish a wired communication connection with the secondary management device 13 via USB, serial port, Ethernet, etc., to achieve data transmission between the personal management device 12 and the secondary management device 13.

[0055] In some embodiments of the present invention, the diabetes management system 10 also includes a remote server, which communicates with the personal management device 12 and / or the secondary management device 13 via Wi-Fi or the Internet, and stores information uploaded by the personal management device 12 and / or the secondary management device 13, or transmits information to the personal management device 12 and / or the secondary management device 13, such as software or firmware update information of the medical device, whether the pairing of the medical device 11 with the management device is successful, whether the medical device 11 is a device that has been used, whether it needs to be updated, etc. For specific methods for updating software or firmware of medical devices, please refer to PCT application: PCT / CN2023 / 114922, the entire content of which is incorporated herein by reference in its entirety.

[0056] The users of the personal management device 12 and / or the secondary management device 13 can be the patient himself, the guardian, etc. who use the same device at the same time, or the patient and the guardian can use different devices respectively. Preferably, the personal management device 12 is a dedicated handheld device (PDM), the secondary management device 13 is a smart phone, the wearable medical device 11 communicates with the PDM via Bluetooth, the PDM communicates with the smart phone via Bluetooth, and the wearable medical device 11 communicates with the smart phone via Bluetooth, mobile cellular, Wi-Fi or the Internet. When the patient and / or the guardian uses the PDM and the smart phone at the same time, it is convenient for the user to choose to use the PDM and / or the smart phone according to the actual situation, such as when one of them is low on power, switch to use the other to control the wearable medical device 11, and when the mobile phone is occupied by other functions such as calls, video recording, meetings, etc., the user can choose to use the PDM to control the wearable medical device 11. When the patient and the caregiver use a device respectively, such as the patient uses PDM and the caregiver uses a smartphone, on the one hand, the patient and the caregiver can view the patient's blood sugar information and monitor the medical device at the same time. On the other hand, the family does not need to purchase more devices, avoiding unnecessary medical expenses. Especially when the patient is an elderly or young child, or a diabetic patient with special diseases who cannot use a management device for self-blood sugar monitoring, the medical staff can turn on the lock mode on the smartphone to limit the patient's operations on the PDM, so that the patient cannot view real-time blood sugar and / or insulin infusion data on the PDM, cannot receive blood sugar alarms, cannot change alarm settings, etc. This can prevent the patient from misoperating the PDM, such as deleting the device, disconnecting the PDM from the medical device, changing the insulin infusion settings, thereby affecting the normal operation of the medical device; not accepting blood sugar alarms can also avoid blood sugar alarms from interfering with or affecting the patient.

[0057] It should be noted that the embodiments of the present invention do not limit the types and quantities of personal management devices and secondary management devices used by patients and / or guardians, that is, patients and / or guardians can use one or more of the same or different devices to control wearable medical devices according to actual needs.

[0058] Figure 2 is a schematic diagram of the structure of an integrated CGM according to an embodiment of the present invention. Figure 3 is a schematic diagram of the structure of a split CGM according to an embodiment of the present invention.

[0059] CGM includes a sensor and a transmitter, which are installed on the patient through an auxiliary installation device and inserted subcutaneously. The sensor is used to collect blood sugar content in the human body and transmit the collected blood sugar content information. The transmitter is connected to the sensor and is used to receive blood sugar data information transmitted by the sensor implanted subcutaneously and convert it into a wireless signal output. Each CGM has a unique identifier, such as a device identifier, hardware identifier, universally unique identifier, serial number, communication protocol-based identifier (such as BLE ID), manufacturer's identifier, etc. The identifier is formed by a combination of multiple randomly combined numbers and letters, which can be set on the CGM shell or packaging, and can also have different settings for different types of CGM.

[0060] Figure 2 is a schematic diagram of the structure of an integrated CGM. This means that the CGM's sensor and transmitter are integrated before use. This CGM is a single-use product that is discarded after use. As shown in Figure 2, the integrated CGM includes a sensor 201, a housing 202, and a transmitter (not shown) housed within housing 202. Sensor 301 monitors the patient's blood glucose data and transmits this data to the transmitter via internal circuitry. The transmitter then transmits this data to a receiver. The identifier can be placed on the CGM's outer housing, packaging, or within the CGM.

[0061] Figure 3 is a schematic diagram of the structure of a split-type CGM. Prior to use, the CGM's sensor and transmitter are two separate components, packaged separately. They are integrated together during use. The split-type CGM includes a base housing 301 and a transmitter 302. The base housing is provided with a sensor 3011, while the transmitter 302 has a separate housing. The base housing 301 and transmitter 302 are provided with snap-fit ​​structures 3012 and 3022, respectively. During use, the base housing 301 and transmitter 302 are snapped together into a single unit via the snap-fit ​​structures. The sensor 3011 is electrically connected to the transmitter 302 via an electrical connector 3013. The sensor 301 monitors a patient's blood glucose data and transmits this data to the transmitter 302 via the electrical connector 3013. The transmitter 302 then transmits this data to the receiver.

[0062] In one embodiment of the present invention, both the sensor and transmitter of a split-type CGM are disposable 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 the present invention, only the sensor of the split-type CGM is disposable, while the transmitter is reusable. Therefore, in this embodiment, the identifier is preferably placed on the housing or outer packaging of the transmitter. This can reduce the frequency of binding patient information and the identifier, thereby improving the patient experience. This will be discussed in detail below.

[0063] When the identifier is provided on the housing or outer packaging of the CGM or transmitter, it may be provided in the form of, but not limited to, a QR code, a barcode, or an NFC tag.

[0064] FIG4 a is a schematic structural diagram of an integrated insulin pump according to an embodiment of the present invention; FIG4 b is a schematic structural diagram of a split insulin pump according to an embodiment of the present invention.

[0065] In an embodiment of the present invention, the insulin pump is a patch-type insulin pump, that is, an insulin pump that does not include a long catheter, includes an infusion structure and a control structure, and is adhered as a whole to the user's skin surface by a same adhesive patch. The drug is directly infused from the drug storage cartridge along the infusion needle into the subcutaneous tissue.

[0066] Each insulin pump has a unique identifier, such as a device identifier, hardware identifier, universally unique identifier, serial number, communication protocol-based identifier, manufacturer's identifier, etc. The identifier is formed by a multi-digit random combination of numbers and letters, which can be set on the housing or packaging of the insulin pump, and can also have different settings for different types of insulin pumps.

[0067] Figure 4a is a schematic diagram of the structure of an integrated insulin pump, that is, the infusion structure 410 and the control structure 400 of the insulin pump are arranged inside the same housing 10, the two are connected by a wire, and are adhered to a certain position on the user's skin through an adhesive patch 420, and are discarded as a whole after one-time use; the identifier can be set on the outer housing or outer packaging of the insulin pump or inside the insulin pump.

[0068] Figure 4b is a schematic diagram of the structure of a split-type insulin pump, in which the infusion mechanism 410 and control mechanism 400 of the insulin pump are housed in separate housings, connected by a waterproof plug or directly snapped together and electrically connected to form a single unit. The identifier can be placed on the outer housing, packaging, or inside the insulin pump itself.

[0069] In one embodiment of the present invention, both the infusion structure and the control structure of a split-type insulin pump are disposable products that are discarded after use. Therefore, the identifier can be set on the housing or outer packaging of the infusion structure and / or the control structure. In another embodiment of the present invention, only the infusion structure of the split-type insulin pump is a disposable product, while the control structure is a reusable product. Therefore, preferably, in this embodiment, the identifier is set on the housing or outer packaging of the control structure. This can reduce the frequency of binding patient information and the identifier, thereby improving the patient experience. This will be described in detail below.

[0070] When the identifier is provided on the housing or outer packaging of the insulin pump or control structure, it may be provided in the form of, but not limited to, a QR code, a barcode, or an NFC tag.

[0071] Before a CGM and / or insulin pump begins operation, it must be properly installed on the skin, and the patient's personal information must be paired with the CGM and / or insulin pump information to enable pairing and control of the management device and the insulin pump. The patient's personal information includes name, age, gender, and mobile phone number, and the information about the CGM and / or insulin pump being worn includes the CGM and / or insulin pump identifier information. In one embodiment of the present invention, the PDM and smartphone are each paired with the medical device to enable control of the medical device. Furthermore, the smartphone can also be paired with the PDM. In another embodiment of the present invention, the PDM is first paired with the medical device to enable control of the medical device, and the smartphone is further paired with the PDM to control the medical device through control of the PDM. Simultaneously, the smartphone uploads the patient's personal information and the CGM and / or insulin pump identifier information to a remote server. The remote server can store the information uploaded by the smartphone and verify the validity of the CGM and / or insulin pump identifier information. If any identifier information already exists on the remote server, the remote server will send a prompt to the smartphone to remind the user that the CGM or insulin pump has been used and needs to be replaced. When the CGM and / or insulin pump is installed on the patient's skin and successfully activated, the CGM and / or insulin pump starts working. The CGM transmitter sends the monitored blood glucose information directly or to the smartphone through PDM, and further uploads it to the remote server. The control structure of the insulin pump receives the insulin infusion information and controls the infusion structure to infuse insulin. At the same time, the infusion status is sent to the smartphone and further uploaded to the remote server.

[0072] It should be noted that the CGM and insulin pump in the embodiment of the present invention are developed and produced by the same manufacturer, and therefore can be controlled by the same dedicated APP or the same PDM in the smartphone. When the patient needs both CGM and insulin pump and CGM at the same time, even if the CGM or insulin pump is produced by other manufacturers, the CGM or insulin pump can be directly controlled by the dedicated APP, and the inconvenience caused to the user by using different APPs to control the CGM and insulin pump separately can be avoided; when the user controls the CGM and insulin pump separately through PDM, since different manufacturers are equipped with dedicated PDMs, the user inevitably needs two PDMs to control the CGM and insulin pump separately, affecting the patient's user experience.

[0073] When the CGM and / or insulin pump worn by the patient needs to be replaced due to reaching the usage cycle or failure, the unique identifier information of the new CGM and / or insulin pump also needs to be paired and updated with the patient's personal information through the management device and further uploaded to the remote server through the smartphone. The patient's personal information is entered manually, and the identifier information of the CGM and / or insulin pump can also be entered manually or by scanning the QR code, barcode, or NFC tag on the shell or outer packaging of the CGM and / or insulin pump.

[0074] When the CGM has a split structure and the transmitter is reusable, the CGM identifier is set on the transmitter's outer shell or packaging. When the patient replaces the CGM, he only needs to replace the sensor without replacing the transmitter. The CGM identifier also remains unchanged. Therefore, there is no need to update the pairing of the CGM identifier and the patient's personal information through a smartphone, nor is there any need to upload it to a remote server. This can reduce the number of operating steps and improve the patient experience.

[0075] When the insulin pump has a split structure and the control structure is reusable, the identifier of the insulin pump is set on the outer shell or packaging of the control structure. When the patient replaces the insulin pump, he only needs to replace the infusion structure without replacing the control structure. The identifier of the insulin pump also remains unchanged. Therefore, there is no need to update the pairing of the insulin pump identifier and the patient's personal information through a smartphone, nor is there any need to upload it to a remote server. This can reduce the number of operating steps and improve the patient experience.

[0076] As mentioned above, when a patient or a guardian uses a PDM and / or a smartphone at the same time, or when a patient and a guardian use a smartphone and a PDM respectively, the smartphone or PDM may be lost for one reason or another. Therefore, in an embodiment of the present invention, a locator is provided in the PDM, and the smartphone itself has a locator. When the PDM and the smartphone are in a communication connection state, the PDM and the smartphone send each other's location information and record each other's location information at the same time. The PDM and the smartphone send each other's location information according to a predetermined rule. Preferably, both periodically send each other's location information and record each other's location information. When the user cannot find the PDM, as shown in FIG5 , the user can check the communication connection status with the PDM on the smartphone. If the status is connected, the user sends an instruction to the PDM via the smartphone. After receiving the instruction, the PDM will issue a prompt to indicate the specific location of the user PDM. The prompt type is a combination of one or more of a sound prompt, a vibration prompt, and a color prompt. The sound type, volume, duration, frequency interval, etc. of the sound prompt; the vibration type, vibration intensity, duration, frequency interval, etc. of the vibration prompt; the color type, color change method and duration, frequency interval, etc. of the color prompt can all be personalized according to actual needs or patient preferences.

[0077] It should be noted that the loss mentioned here may be that the user has temporarily forgotten the location of the smartphone or PDM, but the smartphone and PDM are still in a communication connection state, and still periodically send their own location information to each other, and record the location information of each other; the loss may also be that the user not only forgets the location of the smartphone or PDM, but also the actual distance between the smartphone and PDM exceeds the maximum distance when the two are communicated. Therefore, the communication connection between the smartphone and PDM is disconnected, and they no longer periodically send their own location information to each other, and can no longer record the location information of each other.

[0078] When the communication connection status between the smartphone and the PDM is disconnected, the user can view the location information of the PDM stored on the smartphone, and determine the location of the PDM when it was lost based on the most recent location information stored on the smartphone, thereby quickly finding the PDM. In another embodiment of the present invention, as shown in FIG5 , when the connection status between the smartphone and the PDM is disconnected, the user can view the most recent location of the PDM stored on the smartphone, and use the most recent location of the PDM stored on the smartphone as the destination, gradually move the smartphone closer to the destination while sending a communication connection request to the PDM. When the smartphone is within the communication connection distance of the PDM, it automatically connects to the PDM. After the smartphone establishes a communication connection with the PDM, the smartphone automatically sends an instruction to the PDM. After receiving the instruction, the PDM will issue a prompt to indicate the specific location of the PDM to the user. The specific instruction method is as described above. According to the instruction of the PDM, the user can retrieve the PDM more quickly.

[0079] Similarly, if the user finds that the smartphone is lost, the user can also use the same operation to find the lost smartphone, that is, the user can check the communication connection status with the smartphone on PDM. If the status is connected, the smartphone will be sent an instruction to the smartphone through PDM. After the smartphone receives the instruction, it will issue a prompt to indicate the specific location of the user's smartphone; if the communication connection status between the smartphone and PDM is disconnected, the user can check the most recent location of the smartphone stored on PDM, and use the most recent location of the smartphone stored on PDM as the destination to find the lost smartphone directly at the destination, or gradually move the location of PDM closer to the destination while sending a communication connection request to the smartphone. When the smartphone is within the communication connection distance of PDM, it will automatically connect to PDM. After the smartphone establishes a communication connection with PDM, PDM automatically sends an instruction to the smartphone. After receiving the instruction, the smartphone will issue a prompt to indicate the specific location of the user's smartphone. The specific indication method is as described above.

[0080] When the personal management device and the secondary management device used by the user are the same device, the lost device can also be found in the manner described above, which will not be repeated here.

[0081] In an embodiment of the present invention, when at least one of the personal management device and the secondary management device is a PDM, the PDM communicates with the other device via Bluetooth. Since the communication range of Bluetooth is relatively short, the frequency at which the personal management device and the secondary management device periodically send their own location information to each other when they are in a connected state can be: such as once every 5 minutes, once every 2 minutes, once every 1 minute, once every 30 seconds, once every 10 seconds, or even once every 1 second, or any specified frequency between once every 1 second and once every 5 minutes. When both the personal management device and the secondary management device are smartphones, since smartphones can communicate with each other via mobile cellular, WiFi, or the internet, the communication range is relatively long, and generally speaking, it is not easy for the two to disconnect the communication connection. Therefore, the frequency at which the personal management device and the secondary management device periodically send their own location information to each other when they are in a connected state can be set to be relatively long, such as 10 minutes, 30 minutes, or even one hour. Of course, the embodiment of the present invention does not limit the frequency at which the personal management device and the secondary management device send their own location information to each other, and the user can set it according to actual needs.

[0082] In one embodiment of the present invention, when a personal management device and / or secondary management device fails to receive location information from the other party within a predetermined time interval, the personal management device and / or secondary management device issues an alarm to alert the user that the personal management device and / or secondary management device may be lost. The user is urged to check the location and connection status of the personal management device and / or secondary management device as soon as possible to prevent the device from being lost. If the personal management device or secondary management device is lost, it can be immediately found as described above. If the connection between the personal management device and the secondary management device is disconnected, a communication connection is reestablished to prevent the user from losing the location of the personal management device or secondary management device due to a disconnection, thereby increasing the difficulty of finding the personal management device or secondary management device. The alarm type can be set to a combination of sound, vibration, and interface text. The sound type, volume, duration, and frequency interval of the sound alarm; the vibration type, intensity, duration, and frequency interval of the vibration alarm; and the type and frequency of the interface text alarm can all be customized according to actual needs or patient preferences.

[0083] In an embodiment of the present invention, the predetermined time interval in which the personal management device and / or the secondary management device do not receive the location information of the other party within the predetermined time interval is an integer multiple of the time interval between the personal management device and the secondary management device when they are in a communication connection state. For example, when the time interval between the periodic transmission of location information by the two is relatively long, the set predetermined time can be equal to the time interval between the periodic transmission of location information by the two. If the set predetermined time is too long, the risk of the personal management device and the secondary management device being disconnected will increase, and the risk of the lost device being taken away from the last stored location will also increase, thereby increasing the difficulty of finding the lost device. When the interval between the periodic transmission of location information by the two is relatively short, the set predetermined time can be equal to a multiple of the time interval between the periodic transmission of location information by the two, such as 2-100 times. In this case, on the one hand, it can avoid the personal management device and / or the secondary management device from triggering unnecessary alarms when they fail to send their own location information normally due to random or short-term errors, and at the same time, it can avoid the difficulty of finding the lost device due to the disconnection between the personal management device and the secondary management device.

[0084] In another embodiment of the present invention, when the personal management device and / or the secondary management device are disconnected, the personal management device and / or the secondary management device issues an alarm to remind the user that the connection between the personal management device and / or the secondary management device has been disconnected, prompting the user to re-establish the communication connection as soon as possible to prevent the device from being lost.

[0085] In summary, the present invention discloses a method for finding a lost device applied to a diabetes management system, wherein the diabetes management system includes at least one wearable medical device; at least one personal management device and one secondary management device, at least one of the personal management device and the secondary management device can be used to control the wearable medical device, and the personal management device and the secondary management device are communicatively connected; when one of the personal management device and the secondary management device is determined to be lost, the user can easily retrieve the lost device by finding the lost device through the other of the personal management device and the secondary management device.
