Description

Diabetes management system used in hospitals Technical Field

[0001] The present invention mainly relates to the field of diabetes monitoring and management, and in particular to a diabetes management system used in hospitals. Background Art

[0002] In a healthy individual, the pancreas automatically monitors blood glucose levels and secretes the necessary insulin and glucagon. However, in diabetics, the pancreas malfunctions, preventing it from producing the necessary insulin. Therefore, diabetes is a metabolic disease caused by abnormal pancreatic function and is a lifelong condition. Currently, medical technology cannot cure diabetes; the only approach is to control the onset and progression of diabetes and its complications by stabilizing blood sugar levels.

[0003] Diabetic patients need to monitor their blood sugar before injecting insulin. Currently, most monitoring methods use internal blood sugar monitoring devices to continuously monitor blood sugar. These devices use disposable transcutaneous sensors inserted into the skin to measure blood sugar concentrations in the interstitial fluid and transmit the 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] General diabetic patients can achieve self-monitoring and management of blood sugar through continuous blood glucose monitoring. For diabetic patients with more serious conditions, they need to be hospitalized and adopt targeted treatment plans through doctor's intervention to restore the blood sugar level of diabetic patients to a relatively stable state. At the same time, personalized insulin infusion plans, diet and exercise plans are provided to facilitate patients to achieve self-monitoring and management of blood sugar after discharge.

[0005] Diabetes management systems currently used in hospitals also use disposable transcutaneous sensors worn on the body to continuously monitor blood glucose data. The transmitter connects to a data-receiving device (hereinafter referred to as a receiver) and transmits data. The receiver then sends the blood glucose data to a user-friendly device for medical staff to view, allowing them to view the patient's blood glucose data. Medical staff provide personalized insulin infusion plans for each patient, which are then infused into the patient's body via an insulin pump. The insulin pump simultaneously transmits information about the infused insulin to the receiver, which is then sent to the user-friendly device for viewing, allowing them to view the patient's insulin infusion information. Some in-hospital diabetes management systems send data from multiple medical devices to the same receiver, while others send data from a single medical device to a specific receiver. The typical lifespan of current in-hospital blood glucose monitoring devices is 7-14 days, while that of insulin pumps is approximately 3 days. To conserve battery power and extend the lifespan of monitoring devices, medical devices typically communicate with receivers via Bluetooth. The effective communication distance of Bluetooth is generally 0-20m. When one medical device corresponds to one receiver, if the patient wears the correct medical device and leaves the ward, the distance between the medical device and the receiver is likely to exceed the effective communication distance with the medical device, resulting in the receiver being unable to receive blood glucose and / or insulin infusion data in real time and upload it to the medical staff for display. Therefore, the range of activities of diabetic patients in the hospital is usually limited to a specific ward, which not only gives the patient a strong sense of restraint, but may also affect the patient's other examinations or surgeries. When data from medical devices of multiple patients is sent to the same receiver, not only is the communication distance limitation the same problem, but if the relationship between the multiple medical devices and the patient information is not matched, the blood glucose and / or insulin infusion data received by the receiver cannot be identified and classified according to the patient, resulting in confusion in the matching of blood glucose and / or insulin infusion data with the patient, further affecting the doctor's correct treatment of the patient and endangering the patient's life safety.

[0006] Therefore, the prior art urgently needs a diabetes management system for use in hospitals that does not restrict the patient's range of activities, does not cause the patient to feel restrained, and can correctly match the patient's blood sugar and / or insulin infusion data emitted by the medical device.

[0023] According to one aspect of the present invention, the monitoring screen prominently displays abnormal blood sugar and / or insulin infusion conditions of the patient.

[0024] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0025] The diabetes management system disclosed in the present invention for use in a hospital includes at least one wearable medical device, multiple receivers, a central server, and at least one terminal device used by medical staff. Any of the multiple receivers can receive data sent by the medical device and upload it to the central server.

[0038] As mentioned above, the diabetes management system currently used in hospitals is one in which data from multiple medical devices is sent to the same receiver, or one medical device sends data to a corresponding receiver. Due to the limitation of the communication distance of the medical devices, the patient's range of activities is likely to be restricted to the ward, which not only gives the patient a strong sense of being restrained, but may also affect the patient's other examinations or operations.

[0039] In order to solve this problem, the present invention discloses a diabetes management system for use in a hospital, comprising at least one wearable medical device, multiple receivers, a central server and a terminal device used by medical staff. The receiver receives data sent by the medical device and uploads it to the central server. The medical staff communicates with the central server by using the terminal device and is at least used to display or view medical data information. Since any of the multiple receivers can receive data sent by the medical device and upload it to the central server, the patient's range of activities in the hospital is no longer restricted, which improves the patient experience and keeps the patient in a good mood. At the same time, the doctor can understand the patient's blood sugar level in real time through the terminal device used by the medical staff, and deal with any abnormal situation in time, so that the patient's blood sugar level remains stable.

[0040] 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 of components and steps, numerical expressions and numerical values ​​set forth in these embodiments should not be construed as limiting the scope of the present invention.

[0041] In addition, it should be understood that for ease of description, the sizes of the various components shown in the drawings are not necessarily drawn according to actual proportional relationships. For example, the thickness, width, length or distance of certain units may be enlarged relative to other structures.

[0042] The following description of exemplary embodiments is merely illustrative and is not intended to limit the present invention, its application, or use in any sense. Technologies, methods, and apparatus known to those skilled in the art may not be discussed in detail herein, but to the extent applicable, such technologies, methods, and apparatuses should be considered part of this specification.

[0043] It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined or described in one figure, it will not need to be further discussed in the subsequent figure descriptions.

[0044] FIG1 is a topological diagram of a diabetes management system used in a hospital according to an embodiment of the present invention.

[0045] In an embodiment of the present invention, a diabetes management system used in a hospital includes at least one wearable medical device 11, a receiver group 12 including multiple receivers, a central server 13, a terminal device 14 used by medical staff, and the like.

[0046] Medical device 11 includes a blood glucose monitoring device and / or an insulin pump. The patient-used blood glucose monitoring device is used to monitor the patient's blood glucose level in real time and is installed on the patient via an auxiliary installation device. It 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 blood glucose monitoring device, as well as the blood glucose monitoring device identifier. The patient-used insulin pump includes the infusion structure and control structure necessary for insulin infusion, such as a drug reservoir, 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.

[0047] Any one of the multiple receivers in the receiver group 12 can be used to receive and relay information sent by the blood glucose monitoring device and / or insulin pump, and can be distributed in various locations in the hospital as needed, such as wards, doctors' offices, monitoring rooms, operating rooms, bathrooms, etc., for receiving various data information from the wearable medical device 11, such as patient blood glucose and / or insulin infusion data information, identifier information of the wearable medical device 11, etc. The receiver may include a storage, a processor, a communication interface, etc., and may also send various data information received from the medical device to other devices;

[0048] The central server, data center or cloud, hereinafter collectively referred to as the central server 13, is used to store various types of data information. The central server 13 includes a memory, a processor, a communication interface, etc., can receive and store various types of data information from various receivers, and can also communicate with external devices, such as receivers or medical personnel using terminal devices 14;

[0049] Medical staff use terminal devices 14, such as a mobile device 141 with an operating system for interacting with the central server 13, a hospital information system (HIS system) 142 for viewing or deleting reports, a large monitoring screen 143 for displaying blood sugar and / or insulin infusion information of all patients, etc., which may include memory, processor, communication interface, display, user interface, etc.

[0050] Wireless communication is performed between the wearable medical device 11 and the multiple receivers of the receiver group 12, between the receiver group 12 and the central server 13, and between the central server 13 and the various devices of the medical staff user end 14. The wireless communication can be performed by, for example, but not limited to, radio frequency (RF) communication (e.g., radio frequency identification (RFID), Zigbee communication protocol, WiFi, infrared, wireless universal serial bus (USB), ultra-wideband (UWB), Communication protocols and cellular communications, such as Code Division Multiple Access (CDMA) or Global System for Mobile Communications (GSM). Preferably, the wearable medical device 11 communicates with the multiple receivers of the receiver group 12 via the Bluetooth communication protocol, and the receiver group 12 and the central server 13, as well as the central server 13 and the various devices of the medical staff user end 14, communicate via WiFi and / or cellular communications. It should be noted that in the embodiment of the present invention, the wearable medical device 11 and the various devices of the medical staff user end 14 can also communicate wirelessly, preferably via Bluetooth.

[0051] No matter where the patient is in the hospital, the data sent by the medical device will be received by the receiver at the optimal communication distance, avoiding all receivers or multiple receivers in the receiver group 12 receiving data. On the one hand, it saves power consumption of the medical device, and on the other hand, it prevents each receiver from receiving data and uploading it to the central server, causing duplication of blood glucose / or insulin infusion data information, and also taking up storage space of the central server.

[0052] 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.

[0053] The blood glucose monitoring device is a wearable continuous blood glucose monitoring device (hereinafter referred to as CGM). The CGM includes a sensor and a transmitter. The sensor is used to collect the analyte content in the human body and transmit the collected analyte content information, that is, the sensor is used to collect blood glucose data information in the human body and transmit it. The transmitter is connected to the sensor and is used to receive the blood glucose data information transmitted by the sensor implanted subcutaneously and convert it into a wireless signal for output. It can also output other information, such as the CGM identifier information. Each CGM has a unique identifier, including but not limited to a device identifier, a hardware identifier, a universally unique identifier, a serial number, an identifier based on a communication protocol (such as a BLE ID), a manufacturer's identifier, etc. Preferably, the identifier information is such as the CGM serial number, which is formed by a combination of multiple randomly combined numbers and letters. The serial number can be set on the housing or packaging of the CGM, and can also be set differently depending on the type of CGM.

[0054] Specifically, in one embodiment of the present invention, the CGM is an integrated structure, that is, the sensor and transmitter are integrated together before use, and it is a disposable product that is discarded after use, as shown in Figure 2, which is a schematic structural diagram of an integrated continuous blood glucose monitoring device. The integrated continuous blood glucose monitoring device includes a sensor 201, a housing 202, and a transmitter (not shown in the figure) disposed within the housing 202. The sensor 301 is used to monitor the patient's body fluid blood glucose data information, transmit the above blood glucose data information to the transmitter through an internal circuit, and then send it to the receiver by the transmitter. The identifier can be set on the outer shell or outer packaging of the CGM or inside the CGM.

[0055] In another embodiment of the present invention, the CGM has a split structure, that is, the sensor and transmitter are two different components before use, packaged separately, and are integrated together during use, as shown in Figure 3. Figure 3 is a schematic structural diagram of a split-type continuous glucose monitor. The split-type continuous glucose monitoring device includes a bottom shell 301 and a transmitter 302. The bottom shell is provided with a sensor 3011. The transmitter 302 has a separate housing. The bottom shell 301 and the transmitter 302 housing are provided with snap-fit ​​structures 3012 and 3022, respectively. When in use, the bottom shell 301 and the transmitter 302 are snapped together into a whole by the snap-fit ​​structures. The sensor 3011 is electrically connected to the transmitter 302 via an electrical connector 3013. The sensor 301 is used to monitor the patient's blood glucose data information and transmit the blood glucose data information to the transmitter 302 via the electrical connector 3013. The transmitter 302 then sends the blood glucose data information to the receiver.

[0056] In one embodiment of the present invention, the sensor and transmitter of the split-type continuous glucose monitoring device are both disposable products that are discarded after use. Therefore, the identifier can be set 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 continuous glucose monitoring device is a disposable product, while the transmitter is a reusable product. Therefore, preferably, in this embodiment, the identifier is set 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.

[0057] When the identifier device CGM or transmitter is on the housing or outer packaging, it is provided in the form of, but not limited to, a QR code, a barcode, or an NFC tag.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] When a patient is admitted to the hospital, the medical staff creates a new patient account through the mobile device 141, pairs the patient's personal information with the identifier of the medical device they are wearing, and uploads the patient's personal information and the corresponding identifier to the central server 13. The patient's personal information fields include name, age, gender, department, bed number, ward, diagnosis, hospitalization number, mobile phone number, etc. When the medical device worn by the patient needs to be replaced with a new one due to reaching the end of its service life or failure, the unique identifier information of the new medical device also needs to be paired and updated with the patient's personal information through the mobile device 141 and further uploaded to the central server 13. The central server 13 stores the patient's personal information and the corresponding identifier information. The patient's personal information can be entered manually or by scanning the patient's hospitalization bracelet to automatically match the relevant information. The identifier information can also be entered manually or by scanning the QR code, barcode, or NFC tag on the CGM housing or outer packaging.

[0066] When the CGM is a split structure and the transmitter is reusable, the CGM identifier is set on the outer shell or packaging of the transmitter. When the patient replaces the CGM, he only needs to replace the sensor without replacing the transmitter, and the CGM identifier remains unchanged. Therefore, there is no need to complete the pairing update of the CGM identifier and the patient's personal information through the mobile device 141, and there is no need to further upload it to the central server 13. Therefore, the operation steps can be reduced and the patient experience is improved.

[0067] When the insulin pump is a split structure and the control structure is reusable, the identifier of the insulin pump is set on the 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 complete the pairing and update of the insulin pump identifier and the patient's personal information through a smartphone, and there is no need to further upload it to the central server 13. Therefore, the operation steps can be reduced and the patient experience can be improved.

[0068] When the CGM and / or insulin pump is worn on the patient and starts working, the CGM will send a wireless signal after completing each blood glucose monitoring, and the insulin pump will send a wireless signal after completing each insulin infusion. As mentioned above, preferably, the wireless signal sent by the CGM and / or insulin pump is a Bluetooth signal. In theory, each receiver in the receiver group 12 can receive the Bluetooth signal sent by the CGM and / or insulin pump, but after the Bluetooth signal sent by the medical device is received by a receiver within the optimal communication distance, the medical device will stop sending this blood glucose and / or insulin infusion data signal. On the one hand, it saves power consumption of the medical device, and on the other hand, it prevents each receiver from receiving data and uploading it to the central server, causing duplication of blood glucose and / or insulin infusion data information, and also occupying the storage space of the central server. Here, a receiver within the optimal communication distance may refer to the receiver that first receives the Bluetooth signal transmitted by the medical device worn by the patient. When the signal transmission medium is consistent, e.g., when there are no obstructions or interference between all receivers and the medical device, such as walls, metal structures, WiFi routers, wireless phones, etc., or when the obstructions and / or interference are the same, the receiver within the optimal communication distance refers to the receiver closest to the medical device. However, when the obstructions and / or interference vary, the receiver within the optimal communication distance is not necessarily the receiver closest to the medical device, but rather the receiver that first receives the Bluetooth signal transmitted by the medical device. The Bluetooth signal contains blood glucose and / or insulin infusion data information and corresponding medical device identifier information. The receiver within the optimal communication distance receives the blood glucose and / or insulin infusion data information and the corresponding medical device identifier information and further uploads it to the central server 13. When the patient is in different locations, the blood glucose and / or insulin infusion data and the corresponding medical device identifier information sent by the medical device will be received by different receivers in the optimal communication position. After receiving the blood glucose and / or insulin infusion data and the corresponding medical device identifier information sent by the medical device, the different receivers will upload the corresponding information to the central server 13. In other words, the central server 13 can store all the blood glucose and / or insulin infusion data and the corresponding medical device identifier information received from different receivers.

[0069] Therefore, the storage module of the central server 13 simultaneously stores the corresponding blood glucose and / or insulin infusion data information and the medical device identifier information, as well as the corresponding patient personal information and the medical device identifier information. Generally, the corresponding blood glucose and / or insulin infusion data information and the medical device identifier information, and the corresponding patient personal information and the medical device identifier information are stored in different storage modules of the central server 13. However, the two sets of data are mutually associated, and the patient personal information and the blood glucose and / or insulin infusion data information can be paired using the medical device identifier information, as shown in FIG5 .

[0070] As previously mentioned, when a patient is admitted to the hospital, medical staff will create a new patient account through the mobile device 141 used to implement patient management functions. In addition, the medical staff can also implement account management, device management, blood glucose and / or insulin infusion data information viewing and report printing functions. Specifically:

[0071] When managing patients, after clicking on the new account, you can scan the patient's wristband or manually enter the patient's personal information, scan or manually enter the identifier information of the medical device, and complete the patient's personal information verification through the mobile phone verification code to complete the addition of the patient account. When you need to delete the patient account, you can also delete the corresponding account by clicking Delete.

[0072] During account management, mobile device 141 is equipped with one or more processors, allowing multiple individuals with varying levels of access to modify the mobile device's settings. A attending physician can create a master HCP account, which can then create HCP sub-accounts, add patients, view all patient information, and view operation records for the master HCP account and HCP sub-accounts. The physician also manages hospital-wide HCP sub-accounts, departments, and patients, and has read and write permissions for HCP sub-accounts and departments. Furthermore, the physician can assign access permissions to HCP sub-accounts. For example, a resident physician can be assigned edit permissions to an HCP sub-account, allowing them to modify patient information in the department, add patients, and view all patient information. A nurse, on the other hand, can only be assigned view permissions to an HCP sub-account, allowing them to view all patient information in the department.

[0073] When performing device management, the mobile device 141 can view the status of all connected transmitters and receivers, and can add or delete transmitters and receivers; view the status of all connected infusion structures and control structures, and can add or delete infusion structures and control structures.

[0074] Generally, since CGM and insulin pumps are developed by different manufacturers, each manufacturer has a dedicated handheld device or a dedicated APP on a mobile device to control the corresponding CGM or insulin pump respectively. The handheld devices or APPs from different manufacturers are not compatible. Therefore, medical staff need to switch between different handheld devices or APPs when using them at the same time, and cannot view the user's blood sugar and insulin infusion information at the same time, which causes inconvenience to medical staff.

[0075] In the embodiment of the present invention, the CGM and insulin pump are developed and produced by the same manufacturer. The compatibility of the control of the CGM and the insulin pump is taken into consideration during the development process. Therefore, they can be controlled by a unified handheld device or the same dedicated APP in the same mobile device. Medical staff do not need to switch between different handheld devices or APPs when using them at the same time. They can also view the user's blood sugar and insulin infusion information at the same time, and control the CGM and / or insulin pump at the same time, which greatly facilitates the use of medical staff and improves the user experience of medical staff.

[0076] FIG6 is a default home screen interface of an APP of a mobile device according to an embodiment of the present invention.

[0077] In this embodiment of the present invention, since medical personnel can control CGM and insulin infusion through mobile device 141, blood glucose data and status information of the CGM and insulin infusion information and status information of the insulin pump can be displayed on the main screen of mobile device 141. As shown in Figure 6, the main screen of the mobile device's APP includes a status bar icon area 601. The status bar icon area 601 includes a battery icon 6011 for displaying the remaining battery power status or charging status of the mobile device 141; a time icon 6012 for displaying the current time; an audio icon 6013 for indicating different types of reminders, such as audio, vibration, or audio + vibration; a communication icon 6014 with the insulin pump for displaying the communication connection status with the insulin pump; and an alarm icon 6015 for displaying alarms of different priorities.

[0078] The main screen also displays insulin information, including an insulin delivery status icon 602, an insulin amount that has not yet taken effect in the body 1OB icon 603, and an insulin amount remaining in the insulin pump icon 604. The insulin delivery status icon 602 includes a graphic 6021 and / or text 6022. The graphic 6021 is a circle of different colors, with different colors representing different infusion types, and the progress of the infusion is expressed by the change in color. The text 6022 displays the abbreviation of the insulin infusion type and the infusion rate or infusion progress. When the circle 6021 is gray, it means that the insulin pump is not activated; when the circle 6021 is green, it means that the basal infusion is in progress; when the circle 6021 is a green circle with a dark green portion, it means that the temporary basal infusion is in progress, and the dark green portion indicates the progress of the temporary basal infusion; when the circle 6021 is a blue circle with a dark blue portion, the blue circle indicates a standard bolus infusion, and the dark blue portion indicates the progress of the infusion; when the circle 6021 is a purple circle with a dark purple portion, the purple circle indicates an extended bolus infusion, and the dark purple portion indicates the progress of the infusion; when the circle 6021 is red, it means that the infusion is paused. The text part 6022 Basal (U / H) 1.00 indicates that the current basal infusion rate is 1.00 U / H; Temp Basal (U / H) 1.00: indicates that the temporary basal has been activated and the temporary basal rate is 1.00 U / H; Temp Basal (U / H) 1.00 85%: indicates that the temporary basal rate is 1.00 U / H and is 85% of the current basal rate; Normal (U) 1.00 / 2.00: indicates that the standard bolus is activated and a 1U standard bolus infusion has been completed, with a total standard bolus of 2U; Extended (U) 1.00 / 2.00: indicates that the extended bolus is activated and a 1U extended bolus infusion has been completed, with a total extended bolus of 2U; C-Normal (U) 1.00 / 2.00: indicates that the standard bolus in a mixed bolus is activated and a 1U standard bolus infusion has been completed, with a total extended bolus of 2U; C-Ext. (U) 1.00 / 2.00: indicates that the extended bolus in a mixed bolus is activated and a 1U extended bolus infusion has been completed, with a total extended bolus of 2U; Suspend time remaining 0:15 indicates that the pause is activated and the basal infusion will automatically resume after 15 minutes. In the embodiment of the present invention, the graphic 6021 and the text 6022 cooperate to display the current insulin infusion status. The user can clearly understand the current insulin infusion type, infusion rate or infusion progress through the graphic and text at the same time, and confirm the infusion status of the drug.In other embodiments of the present invention, the main screen may also display the current insulin infusion status only through the graphic 6021 or the text 6022, and the user may also clearly understand the current insulin infusion type, infusion rate or infusion progress.

[0079] The main screen also displays blood sugar information, including a blood sugar graph display area 605 and a CGM status display area 606. The display area 606 displays the most recent blood sugar reading. When the blood sugar value is within the normal blood sugar value range, the blood sugar reading is displayed in green. When the blood sugar value is lower than the low blood sugar standard value, the blood sugar reading is displayed in yellow. When the blood sugar value is higher than the high blood sugar standard value, the blood sugar reading is displayed in red. The blood sugar information also includes a blood sugar trend display area 607. The blood sugar trend display area 607 is displayed with a certain color. The direction and number of arrow indicators display the trend and speed of blood glucose readings using different colors, directions, and numbers. For example, a rightward green arrow indicates stable blood glucose, indicating that the user does not need to pay special attention to their blood glucose level. An upward orange arrow indicates a slow rise in blood glucose, while an downward orange arrow indicates a slow fall in blood glucose, reminding the user to pay attention to further changes in blood glucose. An upward red arrow indicates rising blood glucose, a downward red arrow indicates a falling blood glucose level, and two upward red arrows indicate a rapid rise in blood glucose, reminding the user to monitor blood glucose changes or adjust insulin infusion strategies immediately. Two downward red arrows indicate a rapid drop in blood glucose, prompting the user to take immediate action to change the current blood glucose level, such as carbohydrate supplementation or a bolus infusion. Both the blood glucose reading 606 and the blood glucose trend indicator arrows 607 are located within the circle 6021 indicating the type and progress of insulin infusion, allowing the user to intuitively understand the current insulin infusion status, blood glucose value, and blood glucose trend.

[0080] The blood glucose graphic display area 605 includes a blood glucose reading curve or discrete blood glucose reading points 6051 over a period of time, and a normal blood glucose value area 6052, which facilitates the user to intuitively understand the blood glucose level in the past and current time periods. The normal blood glucose value area 6052 is an area filled with a certain color. In another embodiment of the present invention, the normal blood glucose value range can also be displayed only with highlighted and / or bolded high and low blood glucose standard lines, so that the user can also intuitively understand the blood glucose level in the past and current time periods and the approximate size of the blood glucose change rate.

[0081] The main screen also includes a CGM calibration display area 608. The calibration display area 608 is a water drop icon, and the amount of water drop fill in different colors indicates how long it will take for the next calibration to be completed. The CGM calibration can be completed through the mobile device 141.

[0082] The main screen may also include a pause infusion function icon 609. When the hypoglycemia pause infusion function or the predicted hypoglycemia pause infusion function in the insulin pump is turned on, that is, when the CGM sensor reading triggers the pause function, the insulin pump will perform a safety check and automatically pause the infusion, and the pause infusion function icon 609 will be displayed on the main screen.

[0083] It should be noted that, in the embodiment of the present invention, when the patient does not use a CGM and an insulin pump at the same time, the main screen of the APP of the mobile device 141 only displays the medical data information and status information corresponding to the corresponding CGM or insulin pump.

[0084] Mobile device 141 can also set blood glucose alarms, including global and individual blood glucose alarms. The global blood glucose alarm is the default alarm for all patients. Global blood glucose alarm settings include high blood glucose thresholds, such as 13.3 mmol / L; low blood glucose thresholds, such as 4.4 mmol / L; predicted blood glucose alarms, such as if blood glucose levels rise to 13.3 mmol / L or even 22.2 mmol / L within a certain timeframe (e.g., half an hour or one hour), or fall to 4.4 mmol / L or even 2.2 mmol / L within a certain timeframe; blood glucose rate of change alarms, such as if the rate of rapid rise / fall reaches 0.110 mmol / L / min or even 0.170 mmol / L / min; and low blood glucose alarms, such as if blood glucose falls below 3.1 mmol / L. Global blood glucose alarm settings set the same high / low blood glucose thresholds for all patients. Once any patient's blood glucose level reaches the set thresholds, mobile device 141 will issue an alarm. Depending on the settings, the alarm prompts can include sound, vibration, or a combination of text alerts. 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 type of interface text alarm, the frequency of the alarm, etc. can all be personalized according to actual needs or patient preferences, and can also be set with reference to the content disclosed in patent PCT / CN2022 / 119084.

[0085] Generally, the blood glucose alarm settings for newly added patients are set to be consistent with the global alarm settings by default. If the blood glucose alarm threshold to be set is inconsistent with the global blood glucose alarm threshold due to the patient's physical condition or is in a special stage, such as pregnancy, or due to other diseases, a specific personal blood glucose alarm can be set on the patient management page.

[0086] When medical staff need to check the patient's blood sugar and / or insulin infusion data or print a report, they enter the patient information in the operating system of the mobile device 141 or the HIS system 142. Through the corresponding relationship between the identifiable code and the patient, the corresponding patient's blood sugar data information can be found in the data storage and displayed on the display.

[0087] Specifically, when viewing blood glucose data on mobile device 141, the patient's current blood glucose data and blood glucose trend arrows can be displayed on the real-time monitoring page of patient management. Blood glucose data for recent periods of time, such as 3 hours, 6 hours, 9 hours, 12 hours, 24 hours, or 48 hours, can also be displayed in a curve format. By switching between different time period options, a blood glucose monitoring trend chart for the corresponding time period can be displayed. Similarly, when printing a report, the desired report time and report type can be selected on the print report page of patient management. The report can then be printed, and the electronic copy of the blood glucose report will be automatically saved on mobile device 141. Report types include a comprehensive blood glucose monitoring report, an automatic glucose profile (AGP) chart, and a detailed daily graph. The comprehensive report includes daily and overall statistics of the measured glucose values ​​during the monitoring period. Statistical parameters include: number of measurement points; mean; standard deviation; coefficient of variation; average fluctuation range; maximum / minimum blood glucose values; and blood glucose distribution. The AGP chart displays a blood glucose AGP profile and a blood glucose distribution bar chart for the monitoring period. The following statistics are provided: CGM usage time percentage, mean, standard deviation, coefficient of variation, estimated A1C, mean fluctuation range, mean daily difference, number of daily high / low blood sugar events, etc. The daily detailed graph shows the blood sugar trend graph and simple statistics for each day during the monitoring period.

[0088] The HIS system digitizes, manages, and processes data across all hospital departments and medical activities through network management. It encompasses all aspects of information management, primarily encompassing administrative management systems, medical management systems, decision support systems, and various other auxiliary systems. The medical management system primarily processes information related to the hospital's medical operations, including outpatient and emergency management systems, medical record management systems, medical statistics and query systems, and blood bank management systems. Within the medical management system, various patient blood sugar and / or insulin infusion data reports can be searched, deleted, viewed, and printed.

[0089] The monitoring screen 143 used by the nurse station displays the blood sugar and / or insulin infusion data information of all monitored patients. It also highlights the information of patients with abnormal blood sugar and / or insulin infusion data, such as bed number, name, and abnormal blood sugar and / or insulin infusion data information. Abnormal blood sugar and / or insulin infusion readings are highlighted in different colors, such as high blood sugar readings are displayed in yellow and low blood sugar readings are displayed in red. At the same time, the abnormal blood sugar and / or insulin infusion status of the patient is displayed separately in the form of text on the monitoring screen 143. Through the monitoring screen 143, medical staff, such as nurses, can quickly and clearly understand the blood sugar monitoring and / or insulin infusion status of all patients, and can promptly deal with or feedback any unexpected or sudden situations to the doctor.

[0090] The mobile device 141, HIS system 142, and monitoring screen 143 are different display devices that can provide different user interfaces. The content displayed on the interface, such as the amount, format and / or type of data to be displayed, alarms, etc., can be customized by the manufacturer and / or end user for each specific display device.

[0091] In another embodiment of the present invention, when a patient is in a hospital, a personal diabetes management device may also be configured for the patient, that is, the diabetes management device used in the hospital may also include a personal diabetes management device, the personal diabetes management device is matched with the medical device through the identifier information of the medical device used by the patient, and wireless communication, which may be through, for example, but not limited to, radio frequency (RF) communication (e.g., radio frequency identification (RFID), Zigbee communication protocol, WiFi, infrared, wireless universal serial bus (USB), ultra-wide band (UWB), Communication protocols and cellular communications, such as Code Division Multiple Access (CDMA) or Global System for Mobile Communications (GSM). Preferably, the personal diabetes management device communicates with the medical device via Bluetooth, allowing the patient to immediately understand their blood glucose and / or insulin infusion information, while also learning and becoming proficient in using the personal diabetes management device, so that they can use the management device to monitor and manage their blood glucose levels and administer insulin after discharge. If the patient is an elderly or young child, or a diabetic patient with a special medical condition who is unable to perform self-blood glucose monitoring and insulin infusion, the medical staff can use the lock mode on the mobile device 141 to limit the patient's operations on the personal diabetes management device, preventing the patient from viewing real-time blood glucose and / or insulin infusion data on the personal diabetes management device, receiving blood glucose alerts, or changing alert settings. This can prevent the patient from erroneously operating the personal diabetes management device, such as deleting the device, disconnecting the personal diabetes management device from the medical device, or changing insulin infusion settings, thereby affecting normal blood glucose monitoring and / or insulin infusion by the CGM. Rejecting blood glucose alerts can also prevent blood glucose alerts from interfering with or affecting the patient.

[0092] In an embodiment of the present invention, the personal diabetes management device may also control the CGM and / or insulin pump simultaneously.

[0093] In other embodiments of the present invention, the diabetes management device used in the hospital may further include a secondary management device, which is also matched with the medical device through the identifier information of the medical device used by the patient, and communicates with the patient through wireless communication, which may be through, for example, but not limited to, radio frequency (RF) communication (e.g., radio frequency identification (RFID), Zigbee communication protocol, WiFi, infrared, wireless universal serial bus (USB), ultra-wide band (UWB), Communication protocols and cellular communications, such as Code Division Multiple Access (CDMA) or Global System for Mobile Communications (GSM). Preferably, the personal diabetes management device communicates with the wearable medical device via Bluetooth. Although patients can monitor their blood sugar and / or infuse insulin by themselves, guardians or medical staff can also use secondary management devices to keep abreast of the patient's blood sugar level and / or insulin infusion status. In this case, the content displayed on the secondary management device is consistent with the content displayed on the personal diabetes management device. When the user of the secondary management device is a medical staff, the secondary management device and the mobile device 141 used by the medical staff can be the same device.

[0094] In summary, the embodiments of the present invention disclose a diabetes management system for use in a hospital, comprising at least one wearable medical device, multiple receivers, a central server, and a terminal device used by medical staff. The receiver receives data information sent by the medical device and uploads it to the central server. Medical staff communicate with the central server by using the terminal device and at least display or view the medical data information. Since any of the multiple receivers can receive data information sent by the wearable medical device and upload it to the central server, the patient's range of activities in the hospital is no longer restricted, and the patient remains in a good mood. At the same time, the doctor can understand the patient's blood sugar and / or insulin infusion information in real time through the terminal device used by the medical staff, and deal with any abnormal situation in a timely manner, thereby maintaining the patient's blood sugar level stable.
