Description

Technical Field

[0001] This invention belongs to the technical field of dietary measurement devices for diabetic patients, and particularly relates to the field of measurement devices for gestational diabetes patients, specifically a dietary measurement and recording system for gestational diabetes patients. Background Technology

[0002] High blood sugar in ordinary diabetic patients is a stable state, which can be controlled by a relatively fixed diet combined with blood sugar control medication. Therefore, to ensure the food intake of diabetic patients, various devices for serving diabetic patients' diets have been disclosed in the existing technology. As long as the diet does not exceed the range, safety can be basically guaranteed. For example, CN214964282U is a smart weighing and dispensing plate for diabetic diets, which can measure the amount of staple food, vegetables, and protein meat. There is also existing technology 201810396388.X, a smart diet management system for diabetic patients, which discloses a system to guide diabetic patients' diets. It uses an app to guide patients' daily diets.

[0003] However, gestational diabetes patients are different from ordinary diabetes patients. The main reason for their high blood sugar is related to pregnancy. Therefore, it is necessary to control the diet of gestational diabetes patients more precisely, try to avoid or reduce the use of medication, and pay attention to the 2-hour blood sugar level after each meal. Adjust the diet according to the feedback of the 2-hour blood sugar level, and continuously adjust it to achieve the best blood sugar level to ensure the safety of pregnant patients and their babies.

[0004] This means that traditional diet measuring devices suitable for ordinary diabetic patients cannot meet the dietary regulation needs of pregnant women. In addition, to effectively control blood sugar, pregnant women need to eat small, frequent meals. If family members or patients directly record the types and weights of food and 2-hour postprandial blood sugar levels and report the records to the treating physician for dietary adjustments, this process is very cumbersome and adds a significant burden to pregnant women with gestational diabetes and their families. Therefore, a system is needed that can effectively track and record the types and quality of food consumed by pregnant women, as well as transmit 2-hour postprandial blood sugar levels to the treating physician, to complete the dietary and blood sugar regulation system for pregnant women with gestational diabetes. Summary of the Invention

[0005] To address the aforementioned issues, this application discloses a dietary measurement and recording system for patients with gestational diabetes mellitus.

[0006] Given the unique situation of patients with gestational diabetes, their diet needs to be monitored if persistently high blood sugar levels occur. Besides controlling blood sugar, it's crucial to maintain a balanced ratio of carbohydrates, protein, and fats. Generally, daily intake should consist of 50%-60% carbohydrates, 15%-20% protein, and 25%-30% fat, respectively. In addition, ensuring adequate intake of other micronutrients is also essential. Therefore, to guarantee the health of patients with gestational diabetes, effective blood sugar control while maintaining nutritional balance is necessary. This requires patients to consume a wide variety of foods. Based on the carbohydrate, protein, and fat content of different food groups, the quality of various foods should be calculated to ensure safe intake of carbohydrates, protein, and fat within the patient's range. These food categories should then be allocated according to the proportions at each meal, creating a daily nutrient table and mealtime nutrient tables. The daily diet should include eight types of food. The complexity of recording these factors greatly complicates the dietary record-keeping and registration of patients with gestational diabetes. Furthermore, the need to record blood sugar levels 1 hour and / or 2 hours after main meals undoubtedly increases the workload significantly, leading to decreased patient compliance and potentially impacting the health of both the patient and the fetus.

[0007] This application addresses the above-mentioned problems by disclosing a dietary measurement and recording system for patients with gestational diabetes mellitus, which includes multiple food holding structures for holding one type of food for each meal;

[0008] Multiple food weighing structures, each corresponding to a food holding structure, are used to obtain the weight of the food within the food holding structure.

[0009] A food photography structure, including a camera, is used to capture images of food within the food serving structure;

[0010] The information storage module is used to store various food images and their corresponding food categories;

[0011] The signal transceiver module is used to remotely receive information on the types of food and the weight of each type of food for each meal every day.

[0012] The analysis and control module acquires food images captured by the food imaging structure and corresponding food weight information obtained from the food weighing structure for each food serving structure. It then compares these images with the food images stored in the information storage module to obtain the food names. Next, it uses the correspondence between food names and food categories in the storage module to determine the food category. The module then compares the obtained food category and weight information within each food serving structure with the food category and corresponding weight information received by the signal transceiver module. When the food category and weight information within a food serving structure match any of the food category and corresponding weight information received by the signal transceiver module, a single end message is output. The module then proceeds to the next food serving structure for food analysis until all food category information and corresponding weight information received by the signal transceiver module for a single meal match the food category and weight information within each food serving structure, at which point a complete end message is output.

[0013] The display structure is used to display the food category information and corresponding weight information of each meal received by the signal transceiver module in a table format. When the analysis and control module outputs a single end information, a single end signal is displayed; when the analysis and control module outputs all end information, all end signals are displayed.

[0014] Furthermore, the signal transceiver module is used to receive suggested information about the names of food items corresponding to each meal's food category. It has a corresponding food suggestion bar in its display structure, which displays the names of the food items corresponding to each category.

[0015] Furthermore, a corresponding column for the actual food name is set in the display structure. When the corresponding food category is detected, the name of the food in the corresponding food container structure is displayed in this column table.

[0016] Furthermore, a corresponding "actual weight" column is set up in the display structure. This column is set up to allow operators to easily observe the information in the actual weight column and compare it with the weight information of the corresponding food category received remotely; this allows for a clear understanding of the differences and the appropriate addition or subtraction of the column.

[0017] Furthermore, when the analysis and control module outputs a single end message, the corresponding food category information and food weight information column will display a single end signal; when the analysis and control module outputs all end messages, all end signals will be displayed in the entire food category information and food weight information table.

[0018] Furthermore, the food categories include grains, dairy products, meat and eggs, legumes, vegetables, fruits, oils, and nuts; these eight categories basically cover all food classifications. The nutritional distribution of these eight categories makes the design of the proportions of carbohydrates, proteins, and fats simpler, more convenient, and more random.

[0019] Furthermore, the food imaging structure is positioned above the central area of ​​all food serving structures, ensuring a clear view of all of them. The analysis and control module acquires images captured by the food imaging structure. This module includes an image segmentation module and an image comparison module, used to segment the images in a fixed order, treating each food serving structure as an independent part. The image comparison module compares the same portion between two adjacent images. When a difference is detected between two adjacent images of the same portion, the analysis and control module is activated to identify the food name corresponding to that portion. Alternatively, when a change in the weight information of a food serving structure is detected, the analysis and control module is activated to identify the food name of the corresponding part. This method effectively detects food within the food serving structures and identifies the food categories within them. Additionally, this setup allows for the identification of all food items using a single camera unit, simplifying the overall structural design. Furthermore, the consistent segmentation order ensures that each segmented image corresponds to a specific food serving structure.

[0020] Furthermore, since the gestational diabetes patient system also includes a timing module and an alarm module; after the analysis and control module outputs all the end information, when the analysis and control module detects that the weight of any food container containing carbohydrates has decreased, the analysis and control module sends a timing signal, which is then used to keep track of the time for 1 hour or 2 hours. When the timer is 2-5 minutes before it expires and when the timer expires, the control module sends an alarm message and the alarm module sends an alarm signal.

[0021] Furthermore, a blood glucose detection module is also included to obtain the patient's blood glucose level 1 or 2 hours after the main meal and display it on the display structure.

[0022] Furthermore, the signal transceiver module sends the corresponding food names and post-meal blood glucose information for each food category at each meal to the doctor via the Internet.

[0023] Furthermore, to facilitate operators in preparing food for the following day in advance, a table of food categories and weights for the next 2-3 days is received via a signal transceiver module, and the table is sent out daily.

[0024] Technical effect

[0025] This system does not directly compare food names and weights. Instead, it converts food names into food categories before making the comparison. This method allows for the mapping of carbohydrates, proteins, and fats within a limited range of food categories, quickly determining whether the patient's nutrient ratios meet the nutritional and blood sugar control requirements for gestational diabetes. Furthermore, the system's settings allow for a wide range of foods that patients can consume, as long as they fall within the specified categories. This simplifies food preparation and makes the process faster and easier. The system displays food categories in a structured display, guiding the operator through the preparation process. Additionally, the system displays the food categories and weights for each meal, allowing the operator to focus on the preparation status for each specific meal. Ultimately, the operator only needs to prepare the relevant food categories, requiring minimal memorization and registration, making implementation much simpler. This significantly improves the acceptance of blood sugar control by gestational diabetes patients, ultimately ensuring the health of both the pregnant woman and the fetus.

[0026] Through the effective cooperation of the analysis and control module with other modules, the food name and weight information of the corresponding food category can be easily obtained. This information is then compared with the food category and weight information of each meal received by the signal transceiver module. Finally, the results are displayed on the screen, which can provide the operator with excellent prompts and intuitively verify whether the food name matches the actual food.

[0027] By adding image segmentation and image comparison modules to the analysis and control module, it is possible to identify the names of the food in each food container structure using a single food photography structure, without changing the position of the food photography structure during use, thus ensuring the registration process of subsequent food categories.

[0028] By combining the timing module, alarm module, and blood glucose monitoring module, the blood glucose values ​​of gestational diabetes patients can be obtained effectively and promptly after 1 hour or 2 hours.

[0029] The signal transceiver module is configured to ensure that information on food types and weights can be obtained from the doctor's end. It can also send the names of the food types in the patient's actual diet and the obtained effective blood glucose values ​​to the doctor's end. This allows the doctor to adjust the patient's diet based on the feedback of food names and blood glucose values, ensuring timely and effective feedback-based blood sugar control.

For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0044] refer to Figure 1-7 A dietary measurement and recording system for patients with gestational diabetes mellitus includes a food holding structure 1; a food weighing structure 2; a food imaging structure 3; an information storage module 4; an analysis and control module 5; a signal transceiver module 6; a display structure 7; a timing module 8; an alarm module 9; and a blood glucose detection module 10. Five food holding structures 1 are provided, each used to hold one type of food for each meal. Five food weighing structures 2 are provided, with one food holding structure 1 placed on top of each weighing structure 2, which is used to obtain the weight of the food within each food holding structure 1. The arrangement of five food holding structures 1 and five food weighing structures 2 ensures that five types of food are consumed per meal. The food imaging structure 3 can sequentially identify different foods within the same category and weigh them separately. When preparing food, only one type of food per category can be prepared, ensuring the system's simplicity and convenience.

[0045] refer to Figure 3 The food imaging structure 3 includes a camera 33 for acquiring food images within the food serving structure 1. When in use, the camera 33 is positioned above the central area of ​​all food serving structures 1 to collect image information of all food serving structures 1 from a single camera 33.

[0046] Information storage module 4 is used to store various food images and their corresponding food categories. Analysis and control module 5 retrieves the correspondence between food images and food categories. When a food image is acquired from food photography structure 3, the analysis and control module 5 compares the captured image with the food category.

[0047] The signal transceiver module 6 is used to remotely receive information on the types of food and the corresponding weights of each food type for each day and meal; it also receives a table of food types and weights for the past 2-3 days and sends the table out daily.

[0048] Analysis and control module 5 acquires images of food in each food holding structure 1 captured by food imaging structure 3, along with corresponding food weight information obtained from food weighing structure 2. It then compares these images with the food images stored in information storage module 4 to obtain the food name. Next, it uses the correspondence between food names and food categories in the storage module to determine the food category. Finally, it compares the obtained food category and weight information within food holding structure 1 with the food category and corresponding weight information received by signal transceiver module 6. When the food category and weight information within food holding structure 1 match the information received by any signal transceiver module 6... When the received food category matches the corresponding food category weight information, a single end message is output; the food analysis process proceeds to the next food serving structure 1 until all food category information and corresponding food category weight information received by the signal transceiver module 6 for a single meal match the food category and food weight in each food serving structure 1, at which point all end messages are output; more specifically, when the analysis and control module 5 outputs a single end message, a single end signal is displayed in the corresponding food category information and food weight information column; when the analysis and control module 5 outputs all end messages, all end signals are displayed in the entire food category information and food weight information table.

[0049] refer to Figure 2Display structure 7 displays the food category information and corresponding weight information of each meal received by signal transceiver module 6 in a table format. When analysis and control module 5 outputs a single end signal, a single end signal is displayed; when analysis and control module 5 outputs all end signals, all end signals are displayed. Display structure 7 also includes a "Real Food Name" column. When a corresponding food category is detected, the name of the food in the food container 1 is displayed in this column. This setting allows the operator to clearly see the names of the prepared foods, making it easier to understand the relationship between categories and foods, effectively reducing operator anxiety. Display structure 7 also includes a "Real Weight" column. This column allows the operator to easily observe the difference between the real weight information and the weight information of the corresponding food category received remotely, enabling them to adjust accordingly. The control structure controls the display structure 7 to display the food information table for the next meal 1-2 hours in advance, facilitating advance preparation of ingredients.

[0050] The signal transceiver module is used to receive suggested information about the names of food items corresponding to each meal category. It has a corresponding food suggestion bar on display structure 7, which displays the names of the corresponding food items. This setting can reduce the operator's doubts about preparation, and they can directly refer to the food names to prepare the food.

[0051] refer to Figure 4 The system also includes a timing module 8 and an alarm module 9. After the analysis and control module 5 outputs all end information, when the analysis and control module 5 detects a decrease in the weight of any food containing carbohydrates in the food container 1, it sends a timing signal, which is then timed by the timing module 8 for 1 or 2 hours. Three minutes before the timer expires and again when the timer expires, the control structure sends an alarm message, and the alarm module 9 sends an alarm signal. This method greatly reduces potential memory confusion for the operator during timing, promptly reminding the patient to measure blood glucose. The two reminders, 2-5 minutes before the timer expires and again when the timer expires, are mainly to facilitate the operator's advance preparation, allowing for direct measurement after the timer expires, ensuring the accuracy of the time and test results. A blood glucose detection module 10 is also included to obtain the patient's blood glucose 1 hour or 2 hours after the main meal and display it on the display structure 7. The signal transceiver module 6 sends the corresponding food names and post-meal blood glucose information for each food category of each meal to the doctor via the Internet.

[0052] Food categories include grains, dairy, meat and eggs, legumes, vegetables, fruits, oils, and nuts. These eight categories basically cover all food classifications. The nutritional distribution of these eight categories makes it simpler and more convenient to design the proportions of carbohydrates, proteins, and fats, and also allows for greater flexibility. Choose no more than five food categories per meal to avoid overly complicated preparation.

[0053] Dairy and oily foods are considered liquid foods and can be placed in dedicated liquid containers. The liquid container for oils is smaller to minimize loss on the container sidewalls. Since oils are often not used alone, they can be combined with vegetables. After preparing the ingredients, they can be stir-fried and then placed in the designated vegetable container (1). A cooking wait button can be added during the process. Once cooking is complete, the blood glucose monitoring timer will begin.

[0054] refer to Figure 1 and Figure 7 The camera 33 of the food imaging structure 3 is positioned above the central area of ​​all food holding structures 1, enabling it to clearly capture images of all food holding structures 1. The analysis and control module 5 acquires the images captured by the food imaging structure 3. The analysis and control module 5 also includes an image segmentation module and an image comparison module, used to segment the images in a fixed order, treating each food holding structure 1 as an independent part. The image comparison module compares the same part of two adjacent images. When a difference is detected between two adjacent images of the same part, the analysis and control module 5 is activated to identify the food name corresponding to that part. Alternatively, when a change in the weight information of a certain food holding structure 1 is detected, the analysis and control module 5 is activated to identify the food name of the corresponding part. Through this method, the detection of food in the food holding structures 1 can be effectively completed, thus acquiring the food categories within the food holding structures 1. Furthermore, this setup allows for the identification of all food items using a single camera unit, simplifying the overall structural design complexity. Because the segmentation order is consistent, it ensures that each segmented part of the image corresponds to a specific food holding structure 1.

[0055] refer to Figure 1-7All structures and modules are housed in a single intelligent box, comprising a lower structure 12 and an upper structure 11. The lower structure 12 houses a food holding structure 1 and a food weighing structure 2. The upper structure 11 houses an analysis and control module 5, a display structure 7, a timing module 8, an alarm module 9, and a blood glucose monitoring module. The upper structure 11 has an inner cavity that houses the analysis and control module 5, the display structure 7, the timing module 8, the alarm module 9, the blood glucose monitoring module 10, and a power supply 101. The inner cavity wall prevents the structures within from being affected or contaminated by the lower structure 12 during use. An outlet for the blood glucose monitoring module 10 is also provided within the inner cavity. The lower structure 12 has six receiving slots 121, five of which contain the food weighing structure 2. Above each food weighing structure 2 is a food holding structure 1, which is higher than the receiving slots 121. This arrangement facilitates the placement and removal of the food holding structure 1 and its cleaning; only the food holding structure 1 needs to be cleaned after each use. Another receiving slot 121 houses blood glucose monitoring test strips and puncture needles, reducing the preparation steps for blood glucose monitoring. After the food holding structure 1 is placed in the receiving slot 121, its top extends beyond the slot 121, facilitating the removal of the receiving slot 121. The receiving slot 121 is of uniform size, but multiple food holding structures 1 can be installed to meet the needs of different weights. Except for the liquid holding structure, other solid holding structures can be of a uniform size, serving as a standardized container to hold the maximum amount of food.

[0056] refer to Figure 1-4When the upper structure 11 and the lower structure 12 are combined by interlocking, the food imaging structure 3 is positioned on the protruding structure on the long edge of the lower structure 12. During use, it is rotated to the central area of ​​all food holding structures 1 to capture images of all of them. The food imaging structure 3 includes a horizontal structure 31, a vertical structure 32, and a camera 33. The vertical structure 32 positions the camera 33 at a suitable height, and the horizontal structure 31 positions the camera 33 in the central area of ​​all food holding structures 1 to ensure effective imaging. In non-imaging mode, the food imaging structure 3 is rotated to one side of the lower structure 12. When rotation stops, the vertical structure 32 is parallel to the long edge of the lower structure 12, and the horizontal structure 31 is positioned outside and parallel to the short edge of the lower structure 12. This configuration ensures that once the food is prepared, the patient can directly pick up and eat without interference from the food imaging structure 3. Additionally, to avoid interference, the food imaging structure 3 can be inserted into a socket on the protruding structure. When not in use, the device can be easily removed. A fitting slot for the food photography structure 3 is provided on the upper structure 11 to ensure a suitable placement. The food photography structure 3 can share a power supply 101 with the lower structure 12 or have its own dedicated power supply 101. The power supplies 101 for the upper and lower structures 11 are independent, and both structures also have corresponding Bluetooth modules for short-range wireless data transmission, ensuring data transfer between the two parts. When using a snap-fit ​​design, the display structure 7 is mounted on the outer surface of the upper structure 11, and when in use, it is snapped onto a table with the display structure 7 facing upwards so it can be observed by the user.

[0057] refer to Figure 6-7When the upper structure 11 and the lower structure 12 are hinged together, the food imaging structure 3 is installed on the upper structure 11, and the food weighing structure 2 is electrically connected to the control and analysis module installed on the upper structure 11 through a wiring channel. The food imaging structure 3 has a horizontal structure 31, on which a camera 33 is installed. The camera 33 is located near the long side of the upper structure 11 away from the hinge, and an entry notch 122 for the food imaging structure 3 to be received is provided on the middle wall panel of the inner cavity of the upper structure 11. The horizontal structure 31 is in the imaging state when it extends out of the inner cavity. Structure 31 is positioned above all food holding structures 1. In its retracted state, horizontal structure 31 rotates into the inner cavity. This design ensures that the food does not affect the structures within the inner cavity after rotation and locking. When horizontal structure 31 is extended, upper structure 11 and lower structure 12 are vertically aligned and maintain a stable vertical alignment. This configuration allows for the food imaging structure 3 to be extended for imaging. When a gestational diabetes patient is eating, the food imaging structure 3 is retracted to ensure the patient's normal eating and effectively capture the initial timing of the timing module 8. Display structures 7 are located on the inner and outer sides of upper structure 11. This dual-display configuration allows for observation of relevant data during food preparation and patient eating. After the patient finishes eating, during the timing phase, upper structure 11 and lower structure 12 are locked together, and relevant data can be viewed through the outer display structure 7, facilitating operator access.

[0058] When using this system, refer to Tables 1 and 2. First, the doctor creates a daily calorie and nutrient allocation table based on the patient's blood glucose levels to ensure sufficient calories and a balanced ratio of carbohydrates, protein, and fat. This allocation is then distributed across six meals: three main meals and three snacks. Main meals include five food categories, and snacks include two. This method facilitates meal preparation. After setup, the system receives signals for each meal individually via the signal transceiver module 6, or receives signals and then breaks them down. Finally, the signals are displayed individually on the display structure 7, reducing table complexity.

[0059] refer to Figure 8 Then run the gestational diabetes patient diet measurement and recording system. 1) Signal transceiver module 6 remotely receives the daily food category information and corresponding food category weight information sent by the doctor; food imaging structure 3 obtains food pictures in food holding structure 1; food weighing structure 2 obtains the weight of food in food holding structure 1.

[0060] 2) The analysis and control module 5 obtains food images taken by the food shooting structure 3 for each food holding structure 1 and the corresponding food weight information obtained from the food weighing structure 2. Then, it compares the food images stored in the information storage module 4 to obtain the food name. Finally, it uses the correspondence between the food name and the food category in the storage module to obtain the food category.

[0061] 3) Compare the obtained food category and weight information in the food holding structure 1 with the food category and weight information of the corresponding food category received by the self-receiving signal transceiver module 6; when matching, output a single end information, and when all matches, send out all end information.

[0062] 4) When the weight of any food holding structure 1 containing carbohydrates decreases, the analysis and control module 5 sends a timing signal; the timing time is 1 hour or 2 hours. When the timing is 3 minutes before it is full and when the timing is full, the control structure sends an alarm message and the alarm module 9 sends an alarm signal.

[0063] 5) The collected actual food names of each category of the corresponding meal and the 1-hour and / or 2-hour blood glucose values ​​are provided to the doctor for adjustment. Through long-term high cooperation between doctors and patients, the patient's blood glucose and nutrition are guaranteed.

[0064] It should be noted that Tables 1 and 2 are the daily calorie and nutrient allocation tables and the calorie and nutrient allocation tables for each meal on the doctor's end. These tables can be further displayed on structure 7 for the operator to prepare ingredients in advance. Tables 1 and 2 can be received by the dietary measurement and recording system for gestational diabetes patients through the signal transceiver module 6; Table 3 is the information table for the current meal displayed on structure 7. Taking breakfast corresponding to Table 2 as an example.

[0068] The above description is merely a specific embodiment of this application. Under the guidance of the above teachings, those skilled in the art can make other improvements or modifications based on the above embodiments. Those skilled in the art should understand that the above specific description is only to better explain the purpose of this application, and the scope of protection of this application should be determined by the scope of the claims.

When the food category information and weight information of the corresponding food in the food holding structure match the food category and weight information of the corresponding food category received by any self-signal transceiver module, a single end message is output. The food analysis process continues until all food categories and weight information are matched, at which point all termination information is output. The display structure shows the food category information and corresponding weight information of each meal received by the signal transceiver module in a table format. When the analysis and control module outputs a single end message, a single end signal is displayed; when the analysis and control module outputs all end messages, all end signals are displayed.

2. The system according to claim 1, characterized in that, The signal transceiver module is used to receive suggested information about the names of food items corresponding to each meal category. It has a corresponding food suggestion bar in its display structure, which displays the names of the food items corresponding to each category.

3. The system according to claim 2, characterized in that, The display structure is set with a corresponding column for the actual food name. When the corresponding food category information is detected, the food name in the corresponding food container structure will be displayed in this column table.

4. The system according to claim 2, characterized in that, The display structure includes a corresponding "real weight" column to show the real-time weight of the corresponding food category.

5. The system according to claim 2, characterized in that, When the analysis and control module outputs a single end message, the corresponding food category information and food weight information column will display a single end signal; when the analysis and control module outputs all end messages, all end signals will be displayed in the entire food category information and food weight information table.

6. The system according to claim 1, characterized in that, Food categories include grains, dairy products, meat and eggs, legumes, vegetables, fruits, oils, and nuts.

7. The system according to claim 1, characterized in that, The camera in the food imaging structure is positioned directly above the central area of ​​all food serving structures to capture images of all of them. The analysis and control module acquires the images captured by the food imaging structure. This module also includes an image segmentation module and an image comparison module. The images are segmented in a fixed order, treating each food serving structure as an independent part. The image comparison module compares the same part between two adjacent images. When a difference is detected between two adjacent images of the same part, the analysis and control module is activated to identify the food name corresponding to that part. Alternatively, when a change in the weight information of a food serving structure is detected, the analysis and control module is activated to identify the food name of the corresponding part.

8. The system according to claim 1, characterized in that, The system also includes a timing module and an alarm module. After the analysis and control module outputs all the end information, when the analysis and control module detects that the weight of any food container containing carbohydrates has decreased, the analysis and control module sends a timing signal, and the timing module keeps track of the time for 1 hour or 2 hours. When the timer is 2-5 minutes before it expires or when it expires, the control module sends an alarm message and the alarm module sends an alarm signal.

9. The system according to claim 1, characterized in that, It also includes a blood glucose detection module to obtain the patient's blood glucose level 1 or 2 hours after the main meal and display it on the display structure.

10. The system according to any one of claims 1-9, characterized in that, The signal transceiver module sends the corresponding food names and post-meal blood glucose information for each food category at each meal to the doctor via the Internet; The signal transceiver module receives a list of food categories and weights for the past 2-3 days and sends the list out daily.
