Description

Technical Field

[0001] This invention relates to the field of dietary therapy technology, specifically to an intelligent high-precision weighing device for dietary ingredients for children with diabetes. Background Technology

[0002] The vast majority of children with diabetes have type 1 diabetes, which has a rapid onset, obvious symptoms, and a more severe condition. They are also prone to ketoacidosis. In my country, children with diabetes account for about 5% of the total incidence of diabetes.

[0003] Dietary therapy is the foundation of treatment for all types of diabetes. It is the most important and one of the most fundamental treatment methods for diabetes. Regardless of the type of diabetes, any diabetic patient, at any time, regardless of the severity of the condition, whether there are complications, or whether insulin or oral hypoglycemic drugs are used, should adhere to dietary control in the long term to minimize the impact of diabetes on life and avoid diabetic complications. Summary of the Invention

[0004] To address the aforementioned technical shortcomings, the purpose of this invention is to provide an intelligent, high-precision weighing device for dietary ingredients used in children with diabetes.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This invention provides a dietary therapy method suitable for children with diabetes, comprising the following steps:

[0007] 1. Assessing obesity levels. How much energy should a child consume per day? First, assess the individual's weight: Ideal weight (kg) = Actual height (cm) - 105

[0008] Based on a standard weight, calculate whether you are overweight using the following method:

[0009] Obesity level = (Current weight - Ideal weight) / Ideal weight * 100%

[0010] Calculate Body Mass Index (BMI): BMI = weight (kg) / height * height (m²);

[0011] The degree of obesity is assessed based on the obesity score:

[0012] Obesity score degree of obesity -10％～+10％ normal +11％～+19％ Slightly overweight Greater than +20% obesity -11％～-19％ Thin

[0013] 2. Calculate your total daily energy needs. Calculate your daily total calorie requirements based on your age:

[0014] Daily energy requirement = 1000 + age (years) * (70 to -100) kcal.

[0015] In this formula, children under 3 years old are usually multiplied by 95-100, children aged 4-6 years old by 85-90, children aged 7-10 years old by 80-85, and children over 10 years old by 70-80.

[0016] 3. Calculate the energy content of the three macronutrients. Calculate the energy content of the three macronutrients based on the energy-generating ratio of the three macronutrients in the daily diet of a normal adult, as recommended by the Chinese Nutrition Society:

[0017] Energy supplied by nutrients Total energy protein 12％～14％ Fat 20％～30％ carbohydrate 55％～65％

[0018] 4. Calculate the daily requirements for each of the three major nutrients. Since the coefficients of energy (CFE) of protein, fat, and carbohydrates are 4 kcal / g, 9 kcal / g, and 4 kcal / g, respectively, the daily required amounts of protein, fat, and carbohydrates are as follows:

[0019]

[0020] 5. Adjust the overall nutrient intake. When determining the nutrient intake of children with diabetes based on their age, disease severity, and complications, the following considerations should be taken into account: (1) protein (2) fat and carbohydrates (3) dietary fiber (4) sodium.

[0021] For example: Zhang, an 8-year-old male with diabetes, is in the first grade of elementary school. He is 150 cm tall and weighs 46 kg. He has no obvious complications. How much energy does he need and how should his diet be arranged?

[0022] 1. Assess weight.

[0023] Standard weight = 150 - 105 = 45 kg

[0024] The patient actually weighs 46 kg, and the degree of obesity is (46-45) / 45 = 2.22%, which is within the range of -10% to +10%, and is considered normal.

[0025] BMI = 46 / 1.5 * 1.5 = 20.44

[0026] 2. Calculate the total daily energy intake.

[0027] For children aged 8 years or younger, use a coefficient of (80-85) if the age is between 7 and 10.

[0028] Daily energy requirement = 1000 + 8 * (80 ~ 85) kcal = 1640 ~ 1680 kcal

[0029] 3. Calculate the energy content of the three major nutrients.

[0030] Based on the recommended energy ratios of the three major energy-generating nutrients in the daily diet of normal adults by the Chinese Nutrition Society, the energy requirements of this patient are calculated as follows:

[0031] Protein (1640-1680 kcal) * (12%-14%) = 196.8-235.2 kcal

[0032] Fat (1640-1680 kcal) * (20%-30%) = 328-504 kcal

[0033] Carbohydrates (1640-1680 kcal) * (55%-65%) = 902-1092 kcal

[0034] 4. Calculate the daily requirements for each of the three macronutrients. The daily requirements for the three macronutrients for the child with diabetes in this example are:

[0035] Protein: (196.8~235.2) kcal ÷ 4 = 49.2~58.8 g

[0036] Fat: (328-504) kcal ÷ 9 = 36.44-56 grams

[0037] Carbohydrates: (902-1092) kcal ÷ 4 = 225.5-273 g

[0038] 5. Adjust the overall nutrient intake. No adjustment is needed if the patient has no complications.

[0039] Therefore, we know the daily energy requirements of a normal child, the proportion of energy from the three major energy-providing nutrients, and the amount of energy supplied. Children with diabetes should especially strictly follow the standards for their meals.

[0040] Children with diabetes also have strict limits on their energy intake at each meal. The energy for each of their three meals should be allocated according to their total daily energy intake, and they should eat at regular times and in fixed quantities. They can have 3 to 6 meals a day, eating small meals frequently. This can effectively control blood sugar, and the shorter intervals between meals make it less likely for hypoglycemia to occur.

[0041] For children undergoing simple dietary control, breakfast, lunch, and dinner can be distributed in a 1 / 5, 2 / 5, 2 / 5 ratio, or a 1 / 3, 1 / 3, 1 / 3 ratio, according to their eating habits. It's important to avoid overloading the pancreas with excessive food, which can lead to elevated blood sugar. If there are snacks, the energy from the snacks should be subtracted from the total energy intake of the previous meal. In short, daily energy intake should be strictly limited to the standard range.

[0042] Developing a diet plan also requires following a certain logic and order. The internationally accepted "food exchange" method for diabetes dietary control can be used to diversify the diet. This method categorizes foods according to their source and properties. Foods within the same category contain similar amounts of protein, fat, carbohydrates, and energy within a given weight. Different categories of foods also provide roughly the same amount of energy. For diabetic patients, the advantages of food exchange include, but are not limited to: (1) ease of achieving balance; (2) convenience in calculating total energy; (3) ensuring food diversification; and (4) flexibility.

[0043] The food exchange system used by the Nutrition Department of Peking Union Medical College Hospital in my country divides food into four or eight subcategories, with each serving containing roughly the same amount of calories, approximately 90 kcal. Foods within the same category can be freely interchanged. The specific food "portions" are as follows (all weights refer to raw weight):

[0044]

[0045] The first step in creating a menu: Determine the amount of staple food.

[0046] After determining the total daily energy intake, the first step is to determine the amount of staple food.

[0047] Staple foods such as rice, corn, millet, and flour contain about 80% carbohydrates, making them the main source of calories in our daily diet. Diabetic patients must control their intake of staple foods, but it's not true that the less staple food you eat, the better. This is because everyone's daily calorie needs come not only from staple foods, but also from other foods (such as meat, eggs, milk, and cooking oil), which can also raise blood sugar levels. Since the carbohydrates in staple foods also stimulate insulin secretion, the proportion of carbohydrates should be appropriately increased, ideally with a daily carbohydrate calorie ratio of no less than 50%. Specific dietary guidelines for each patient should be based on the amount of staple food consumed.

[0048] Relationship between different total energy and staple food weight

[0049]

[0050]

[0051] Note: The numerical relationship above can be simplified to: Daily staple food intake (grams) = 0.25 * Total daily energy - 150. The amount of staple food corresponding to an energy intake below 1200 kcal is not listed above because, generally, an adult's daily energy intake should not be less than 1200 kcal, and therefore, staple food intake should not be less than 150 grams (3 liang) per day. Insufficient intake may cause a negative energy balance, leading to weight loss and potentially hypoglycemia.

[0052] Step 2 in creating a meal plan: Determine the amount of side dishes

[0053] Generally, the daily side dishes and their quantities for diabetic patients are roughly as follows:

[0054]

[0055] Different energy levels in diabetic diets

[0056]

[0057]

[0058] Equivalent dairy product exchange table

[0059] Each serving of dairy provides 5 grams of protein, 5 grams of fat, 6 grams of carbohydrates, and 90 kilocalories.

[0060] food Weight (grams) food Weight (grams) milk powder 20 milk 160 skim milk powder 25 goat milk 160 cheese 25 Sugar-free yogurt 130

[0061] Equivalent Fruit Exchange Table

[0062] Each serving of fruit provides 1 gram of protein, 21 grams of carbohydrates, and 90 kilocalories.

[0063] food Weight (grams) food Weight (grams) Persimmons, bananas, and fresh lychees (with peel) 150 Plums and apricots (with skin) 200 Pear, peach, apple (with skin), star fruit 200 Grapes (with skin) 200 Oranges, tangerines, and grapefruits (with peel) 200 strawberry 200 Kiwi fruit (with skin) 200 watermelon 500

[0064] Equivalent Vegetable Exchange Quantity

[0065] Each serving of vegetables provides 2 grams of protein, 20 grams of carbohydrates, and 90 kilocalories.

[0066]

[0067] Equivalent Meat and Egg Exchange Table: Each exchange serving of meat and eggs provides 9 grams of protein, 6 grams of fat, and 90 kilocalories.

[0068]

[0069] Equivalent Legume Exchange Table

[0070] Each serving of soybeans provides 9 grams of protein, 4 grams of fat, 4 grams of carbohydrates, and 90 kilocalories.

[0071]

[0072] Equivalent Grain and Tuber Exchange Table

[0073] Each serving of grains and tubers provides 2 grams of protein, 20 grams of carbohydrates, and 90 kilocalories.

[0074]

[0075] Equivalent Oil and Fat Food Exchange Table

[0076] Each serving of oils provides 10 grams of fat and 90 kilocalories.

[0077]

[0078]

[0079] Patients and their families need to learn about food interchange. Its biggest advantage is that similar foods or foods with similar nutrient content can be interchanged, providing patients with a wide range of food choices. However, there are two key points to note:

[0080] (1) Interchanging food of the same kind and different kinds

[0081] Different staple foods and side dishes (such as different vegetables, fruits, meats, legumes, oils, and nuts) can be interchanged. The amounts that can be interchanged have been explained in detail above; for example, 50 grams of rice can be interchanged with 50 grams of noodles; 25 grams of biscuits can be interchanged with 35 grams of cornbread, etc. Foods with similar nutrient content can also be interchanged, but the situation is slightly more complex, and common examples are as follows:

[0082]

[0083] (2) Exchange of raw and cooked food

[0084] The weight of food changes significantly after cooking. Unless otherwise specified, the food quantities mentioned below refer to raw weight, not the cooked weight as measured in everyday life. Therefore, diabetic patients should be aware of the interchangeable weights of raw and cooked foods when preparing and weighing their meals.

[0085] The following lists the interchangeability of raw and cooked foods for reference.

[0086] Food raw and cooked interchangeability

[0087] 1 tael of rice 50 grams raw weight 130 grams of cooked rice 1 tael of flour 50 grams raw weight Cooked weight (steamed bun) 75 grams 1 tael of meat 50 grams raw weight 35 grams (cooked)

[0088] Combining the "Relationship between Different Total Energy and Staple Food Weights," "Daily Side Dishes and Their Quantities for Diabetic Patients," and the food exchange tables, the above rules can be roughly simplified into the following food structure table with upper and lower limits, which can be used to standardize and determine the range of food exchange portions:

[0089] Ingredient Structure Table

[0090]

[0091] As can be seen from the above, under normal circumstances, there are clear upper limits for meat, beans, and staple foods, while there are no upper limits for vegetables and fruits. Other types can be adjusted appropriately around the recommended values.

[0092] A diabetic diet is one that requires calculation and weighing. Regarding the application of food exchange portions, the above example will also demonstrate how to plan a meal plan. Follow these steps to create a meal plan:

[0093] Step 1: After calculating the patient's total daily calorie requirement as 1640-1680 kcal, directly calculate the number of food exchange portions: (1640-1680) ÷ 90 = 18.22-18.67 portions.

[0094] Step 2: Plan the actual food exchange portions for the three meals based on the reference range in the "Ingredient Structure Table". In this example, the patient's staple food weight is (1640-1680) kcal * 0.25 - 150 = 260-270. Dividing this by the weight of 25 grams for one exchange portion of most grains and tubers, the number of exchange portions for grains, tubers, or whole grains is 10.4-10.8. Adding nuts, the lower limit of the food exchange portion is already greater than 18.67, reaching 19.9625. Considering that this lower limit is set as an average for the general population and is for reference only, the food exchange portions for some food items can be appropriately reduced in children. Therefore, the diet plan is as follows:

[0095] Recipe Structure Table

[0096]

[0097] Refer to the table above to allocate food exchange portions (users can also manually increase or decrease each food exchange portion as needed), and increase the selection of foods recommended above for this type of patient, such as: ① Sea fish: to supplement protein and unsaturated fatty acids; ② Milk: to supplement protein and calcium. Patients choose and exchange foods according to their own habits and preferences. The following diet plan can be designed using food exchange portions:

[0098]

[0099] In fact, similar foods can be substituted for each other. 25 grams of rice can be substituted for 25 grams of red bean powder; 25 grams of lean meat can also be substituted for 20 grams of ham, and so on.

[0100] Foods of the same type can be interchanged when their nutrient structure is similar. 25 grams of soda crackers can be substituted for 150 grams of banana, as their calorie and carbohydrate content is roughly equivalent. Without increasing total daily calorie intake, eating 150 grams of banana and 25 grams of soda crackers is the same. When blood sugar is stable, a patient can eat one serving of fruit daily, reducing the soda crackers by 25 grams.

[0101] Therefore, as long as people are familiar with using food exchange portions, they can choose a variety of foods without increasing their total calories and fat intake, including fruits, potatoes, vermicelli, and carrots that they previously dared not choose.

[0102] The purpose of snacking is to help blood sugar levels stabilize and reduce the burden on the pancreas. In particular, snacking before bed can effectively prevent nocturnal hypoglycemia. Therefore, it is recommended that diabetic patients have regular nighttime snacks, rather than waiting until they feel hungry.

[0103] When preparing ingredients, it is important to pay attention to various commonly used units of measurement:

[0104]

[0105] Therefore, when creating a diet plan that is accurate in calories and diverse in ingredients, the only information needed from the patient is: ① age; ② height; ③ weight; ④ occupation. Following these specific steps and rules, a corresponding diet plan can be created. For children with diabetes, only the first four essential pieces of information are required to create a diet plan.

[0106] For each individual, these four essential pieces of information are objective, thus the structure of each individual's corresponding diet is relatively stable. On the other hand, the steps and rules for creating a diet are specific or procedurally fixed, and the ingredients are quantifiable and standardized. This makes it feasible and efficient to automatically generate a series of reasonable diets with diverse ingredient choices based on the four essential pieces of information. Currently, for a large number of diabetic patients, mastering the rules for diet planning under different conditions and comorbidities is extremely difficult. There are no highly precise measurement standards or unified planning rules for diets at different times. There are also no unified evaluation standards for assessing the diets of multiple or even large groups of diabetic patients. Furthermore, there is a lack of standards and criteria for different researchers to conduct nutritional intake tests on patients in different dietary or nutrition-related experiments.

[0107] In the same nutritional experiment, the test subjects' different states at different times, and the standards for these states are highly variable, which may lead to a significant bias between the test results and the actual situation of the patients in the experiment. When comparing different nutritional experiments, this bias may be even greater because the evaluation criteria are uncontrollable.

[0108] When developing dietary plans, the aforementioned shortcomings of traditional methods—such as imprecision and the inability to accurately confirm the extent (type and quantity) or changes in a patient's existing dietary nutrient intake—lead to data contamination during observation and recording, resulting in errors in subsequent correlation analyses. For patients, this can lead to significant problems in the long run, including failure to achieve goals such as calorie control, blood sugar control, and even complication prevention. To meet the requirements for accurate measurement of information such as the calorie content of food in high-stability blood sugar control and stabilization experiments for diabetic patients, the following invention will describe its contents in detail and systematically.

[0109] This invention is proposed to solve the above-mentioned problems. Its purpose is to provide a simple, standard, and accurate recipe that uses simple programming to control the structure of ingredients and to provide recipes for multiple categories of ingredients, single-category diversified ingredients, and their effective weight or volume. This greatly improves the accuracy and reliability of recipe results under certain ranges of calories and high standard nutritional requirements.

[0110] This intelligent, high-precision weighing device for dietary ingredients for children with diabetes allows for the creation of compliant meal plans after simple instruction. It provides results such as calorie range, food exchange servings, dietary structure for three meals, specific ingredient contents, equivalent weight (grams) of each ingredient, edible weight (grams), dish name, and auxiliary functions to confirm completion status.

[0111] This recipe provides a reliable basis for variety and data, which is conducive to subsequent related analyses such as nutritional components. This allows for the accurate quantification of the correlation between dietary treatment in children with diabetes and other aspects of the experiment. For example, in functional magnetic resonance imaging (fMRI), the activation location and degree of brain regions stimulated in children with diabetes can be numerically quantified and correlated with the intake values ​​of specific nutrients to determine whether the stimulation location and degree of different brain regions are related to excessive or insufficient intake of that nutrient.

[0112] Furthermore, the present invention also aims to:

[0113] 1. To provide an electronic watch that can be easily programmed by a computer, thereby accurately prompting diabetic patients to prepare, select, weigh, and cook food so as to eat on time.

[0114] 2. Provides an electronic watch with an audible bell indicating the end of the time, which can accurately indicate the start time for diabetic patients and clearly provide patients within a certain distance with the message that it is time to start preparing food, so as to accurately begin weighing.

[0115] 3. Provides a simple time increment / decrement button for preset reminder times. A quick double press of the blue button selects either hour or minute, while slower presses increase the measurement time to a maximum of 60 seconds. A white button next to it decreases the measurement time to a minimum of 0 seconds.

[0116] 4. Provide a tray device for carrying a considerable weight of solid food ingredients, ensuring the cleanliness and integrity of the solid food ingredients, and ensuring that the ingredients are within the effective weighing area during weighing.

[0117] 5. A measuring cup device is provided for holding a considerable weight of liquid food. The device ensures the cleanliness, portability, and mobility of the liquid food, and that the liquid is placed within the effective weighing area during weighing.

[0118] 6. Provide a weight display screen similar to that of a blood pressure monitor, digitally displaying the final weighing data and comparing the result with the edible weight (grams) data in the recipe. When they match, a "beep" sound will indicate that the weight is consistent. This facilitates accurate comparison and detailed recording, and also helps in the subsequent detailed and in-depth analysis of related research structures.

[0119] 7. Provide a touchscreen recipe display screen. Doctors, nutritionists, or other users can input their age, height, weight, and occupation via a mobile app. The system automatically calculates BMI, obesity level, degree of obesity, work intensity, daily energy requirements, daily nutritional ratio (carbohydrates, protein, fat), and generates the day's recipe, recipe details (meal types, ingredient categories, number of food exchanges, total number of food exchanges, ingredient name, equivalent weight (grams), consumption weight (grams), dish name, completion status, etc.), and displays these results on the recipe display screen via Bluetooth or network connection. Users can click the bright blue circle indicating completion to turn it into a dark blue ring, confirming the completion of the weighing step for that ingredient and proceeding to the next ingredient. Even if the weighing is incorrect, the user can proceed to the next step, but the button will remain displayed as a bright blue circle.

[0120] 8. Provide a rechargeable USB data cable for importing and exporting recipes and other information. It can import confirmed recipes and export recipes from the backend hard drive for long-term dietary follow-up, retrospection, and comparative analysis.

[0121] 9. A switch is provided for easily starting the device. The weighing equipment can be started simply by touching the button as needed.

[0122] 10. A battery device that can be easily replaced, allowing the battery to be replaced as needed and easily removed when not in use, thus saving energy.

[0123] 11. A charging port device is provided that allows for easy charging, enabling simple connection to a power source for charging when there is no power or the battery is low and the device is not in use.

[0124] 12. A selector button device with interchangeable units (g / oz) is provided. This device allows for easy and flexible switching of the required weight unit according to the needs of weighing or research, and displays the weight on the left-hand weight display screen.

[0125] 13. A selector button device is provided that allows for the selection of whether to remove the weighing carrier (tare, ~o~). This device allows for easy and flexible reset of the initial weight to 0 after adding the weighing carrier (tray, measuring cup, etc.) according to the needs of weighing or research, and displays the weight on the left-hand weight display screen.

[0126] 14. A device for detachable and replaceable recipe display screens is provided. This device allows for easy and flexible replacement of outdated, damaged, or aging recipe display screens according to the needs of repeated weighing or research, thus saving resources and conserving other equipment. It also facilitates the rational recycling of aging screens and the reuse of usable materials.

[0127] 15. Provides a simple, portable structure that is easy to disassemble, clean, and wash, making it easy to keep clean. It is compact, lightweight, and easy to carry when traveling.

[0128] Finally, the purpose of this invention is that this standardized device is simple, inexpensive, and easy to reproduce, and can be extended to all uncomorbid populations requiring calorie control and related research.

[0129] In summary, this device enables the quantitative design of key dietary plans for patients with diabetes and nephropathy, and also allows for the following research: 1. Analyzing the feasibility of novel treatment methods based on specific calorie or nutrient intake through correlation analysis. 2. Monitoring the hypoglycemic effects of the same treatment method after different calorie intakes to identify the optimal calorie values. 3. Comparing the recovery and stabilization of blood glucose levels after different treatment methods. 4. Assisting in researching the correlation between blood glucose recovery effects and various drug therapies, physical therapies, and exercise therapies.

[0130] Technical solution:

[0131] To achieve the above objectives, before setting up the device of this invention, the initial value for weighing should be set to 0 according to the project requirements. Different kitchens or laboratories can set different weighing units as needed, and the units should be noted in the weighing results for reference in terms of food usage and related research. The following scheme will mainly use food types and weights within the range of 1640-1680 kcal as examples. For instance, in this example, the number of food exchange portions for the patient is 18.22-18.67 portions.

[0132] The device's built-in program or an Excel spreadsheet system can recommend the following recipe planning based on a series of rules:

[0133] Recipe Structure Table

[0134]

[0135] According to the plan, the number of food exchange portions for various ingredients in the three meals can be arranged in Excel as follows. Users can also manually increase or decrease each food exchange portion as needed. It is recommended that users frequently select ingredients that this type of patient should eat more of, such as ① seafood: to supplement protein and unsaturated fatty acids; ② milk: to supplement protein and calcium. After selecting the ingredient name, the equivalent weight (grams), the consumption weight (grams), and the name of the recommended dish will be automatically displayed.

[0136]

[0137] Specifically, under the "Number of Servings for Food Exchange" column, there is a "Total Number of Servings for Three Meals" column, with a target value maintained between 18.22 and 18.67. In the "Ingredient Name" column, the specific ingredients in each category are optional (using Excel's optional operation settings). The selection range is the content from the previous "Equivalent Values ​​of Various Food Exchanges" table (more can be added later). The equivalent weight (grams) is the weight (grams) from the previous "Equivalent Values ​​of Various Food Exchanges" table. For example, the formula for the space containing the equivalent weight (grams) of dairy products is "=LOOKUP(E6,{"Milk Powder","Skimmed Milk Powder","Cheese","Milk","Goat Milk","Unsweetened Yogurt"},{20,25,25,160,160,130})". The consumption weight (grams) is the result of multiplying the number of exchange servings of a specific ingredient by its equivalent weight (grams). Each dish name row has a background color; ingredients with the same background color are grouped into the ingredient section of that dish. The circle on the right is the one you can tap to confirm completion. Once each ingredient has been weighed to the correct weight, a "beep" sound will be emitted. Confirmation can be done automatically by the software or manually by tapping the circle.

[0138] The present invention relates to an intelligent high-precision weighing device for dietary ingredients for children with diabetes. The weighing device includes at least one electronic watch, an electronic watch bell port, two time increment / decrement buttons, a tray, a measuring cup, a weight sensor, a weight display screen, a recipe display screen, a USB interface, a switch, a battery device, a charging port device, a charging cable that also serves as a data cable device, a selector button device for changing the unit (g / oz), a selector button device for changing whether to remove the weighing carrier (tare, ~o~), and a detachable recipe display screen device.

[0139] The main body of this intelligent high-precision weighing device for dietary ingredients for children with diabetes is made of edible ABS plastic, which is waterproof, dustproof, and easy to clean.

[0140] A high-precision weight sensor is placed below the circular weighing area, providing highly accurate weight data. It can intelligently and sensitively sense every gram, with an accuracy of 0.01g, meaning it can accurately detect even a feather. The maximum load capacity is 10kg, and it is suitable for weighing a wide range of objects, including food and medicinal herbs.

[0141] The time and weight display of the electronic watch is a plastic electronic display, similar to the display of an electronic blood pressure monitor.

[0142] The electronic watch's time display shows two times: a smaller display in the upper left corner shows the scheduled time for the next meal preparation, while the larger display in the center shows the current standard time. Users can adjust the scheduled meal preparation time by pressing three different colored buttons next to the time display. Light blue is the time increment button, dark blue is the time decrement button, and white is the selection button, allowing selection between the preset time and the standard time, or between hours and minutes. A small sun-shaped beeping device in the upper right corner of the display emits an alarm sound. A "beep" indicates that the meal preparation time of 11:00 or other set times has arrived. Pressing the beeping device or the alarm bell on the mobile app will silence the alarm. The preset reminder function remains active regardless of whether the device is powered on or off.

[0143] The entire operation is controlled by a single switch. This push-button switch is located in the center of the weighing scale; a light press starts the device. To the right of the switch are two buttons: one for changing the unit (g / oz) and another for selecting whether to remove the weighing medium (tare, ~o~). A light press changes the weighing unit or selects whether to weigh using the tare method. Convertible units include grams / g and ounces / oz. Users can easily switch units with a single press, flexibly handling various proportions and efficiently weighing liquids and solids, making meal preparation smoother. The option to remove the weighing medium (tare, ~o~) allows for one-touch zeroing. Both buttons are large, convenient buttons, simple to operate, and save time and effort.

[0144] Commonly used weighing media include large and small trays, and measuring cups. Large trays are roughly cubic in shape; small trays are disc-shaped. Measuring cups are standardly available in four units: deciliters, milliliters, ounces, and cups, allowing users to choose the appropriate unit. Trays and measuring cups are made from edible materials, and various sizes can be designed and manufactured to suit different weights. For example, time and weight displays on electronic watches can be manufactured and supplied by general instrument manufacturers. Recipe displays can be manufactured and supplied by electronic instrument manufacturers. All of these components are detachable and replaceable.

[0145] The recipe display screen is located below the weighing area of ​​the weighing device. It is a large, touch-sensitive LCD electronic display, 15cm long and 8cm wide, or other suitable sizes. It is intelligent and high-definition, with a clear backlit display. The panel is waterproof, smooth, and easy to clean; it can be wiped clean with a simple wipe. This recipe display screen features a large, high-definition LCD screen, providing clear readings, even at night. It easily handles various scenarios, facilitating meal preparation and other culinary creations, preventing poor visibility during use.

[0146] Each time users input their age, height, weight, and occupation through the mobile app, the recipe display screen automatically shows this information. The software calculates work intensity, BMI, obesity level, degree of obesity, daily energy requirements, and daily nutritional ratios (carbohydrates, protein, and fat) based on predefined rules. It then recommends one item from each food category under the "Food Exchange Servings" column, with the total sum falling within the range of food exchange servings. Users can also manually increase or decrease the number of food exchange servings.

[0147] The formulas for calculating these contents are:

[0148] BMI = weight (kg) / height * height (m²);

[0149] Obesity level = (Current weight - Ideal weight) / Ideal weight * 100%

[0150] Daily energy requirement = Ideal body weight (kg) * Calories burned per kilogram of body weight per day = [Actual height (cm) - 105] * Calories burned per kilogram of body weight per day (see the table of calories burned per kilogram of ideal body weight (kcal) above, and the reference standard for labor intensity classification proposed by the Chinese Nutrition Society in October 1989).

[0151] Calculate the daily nutritional ratio (carbohydrates, protein, fat):

[0152] Energy provided by protein (kcal) = Daily energy requirement (kcal) * (12%–14%)

[0153] Energy provided by fat (kcal) = Daily energy requirement * (20%–30%)

[0154] Energy provided by carbohydrates (kcal) = Daily energy requirement * (55%–65%)

[0155] Calculate the weight of the three macronutrients and enter the weight value in the header column of the table:

[0156] Weight of protein (grams) = Energy provided by protein (kcal) ÷ ​​4

[0157] Weight of fat (grams) = Energy provided by fat (kcal) ÷ ​​9

[0158] The weight of carbohydrates (grams) = Energy provided by fat (kcal) ÷ ​​4

[0159] Finally, confirm whether there are any complications and whether the overall amount of nutrients needs to be adjusted.

[0160] The recipe display screen shows elements including the day of the week in the header row, five main eating time zones on the left, the first row category, the number of food exchange portions, ingredient name, equivalent weight (grams), edible weight (grams), dish name, and completion. In the category column, breakfast includes pre-meal vegetables, water, dairy, fruit, vegetables, meat, eggs, beans, whole grains, oil, seasonings, and nuts; snacks include fruit and whole grains; lunch includes fruit, vegetables, meat, eggs, beans, whole grains, oil, seasonings, and nuts; and dinner includes fruit, vegetables, meat, eggs, beans, whole grains, oil, seasonings, and nuts. Users can double-click on a row in a category to add ingredients to that category, allowing them to add different specific ingredients of a single type to ensure food diversity.

[0161] In the food exchange portion count section, the software system will automatically recommend a set number of food exchange portions, ensuring the total sum falls within the range. Within each category with recommended exchange portion counts, the user selects the desired ingredients, and a subsequent column will automatically display their equivalent weight (grams). The ingredients and their equivalent weights (grams) are listed in a series of tables in the background section, including equivalent dairy, fruit, vegetable, meat / egg, legume, grain / tuberous, and oil / fats exchange tables. The content and types of ingredients will be continuously updated during use. The edible weight (grams) column will calculate the edible weight (grams) using the following formula: Edible weight (grams) = Equivalent weight (grams) * Number of food exchange portions.

[0162] In the dish name column of the recipe table, the recipe table will automatically categorize each ingredient into which dish and uniformly color the background of these ingredients.

[0163] In the "Completed" column of the recipe form, users can click the "Confirm" button to change the original light blue circle to a dark blue ring to confirm that the weighing step for that ingredient is complete, and can then proceed to the weighing step for the next ingredient. If the weighing is incorrect, the user can still proceed to the next step, but the button will still be displayed in light blue, indicating that the weighing of that ingredient item has not yet been completed.

[0164] The battery replacement part is located at the rear of this intelligent high-precision weighing device for children with diabetes. The easy-to-pry cover forms a flip cover over the battery, which can be easily lifted to replace the battery with a new one, such as two AAA batteries, which will provide power.

[0165] The USB charging port is located on the left or right side of the scale, making it easy to insert a USB charging cable to power or replenish the energy reserves of this intelligent, high-precision weighing device for children with diabetes. The charging device completes a full charge in 15 minutes and can last for 3 months or longer.

[0166] The beneficial effects of this invention are as follows:

[0167] Because this device can precisely and cleverly avoid dietary restrictions, accurately create personalized recipes for children with diabetes, and open up a kitchen-based dietary therapy path for them with high-precision standardized weighing of ingredients, and can flexibly adjust the contents of ingredients to increase food diversity, it can greatly improve patient compliance, help users significantly increase the success rate of blood sugar control, maintain the effectiveness of blood sugar stability, and long-term use can help patients improve the cure rate of the "five-horse carriage" treatment method.

[0168] In particular, unlike other food weighing devices, this apparatus is made entirely of waterproof, food-grade material, allowing it to be placed on any slightly damp flat surface. It is small and space-saving. Furthermore, the device is relatively inexpensive and simple to manufacture. Different laboratories can produce it in nearby factories, facilitating the development of new dietary therapy methods, optimization of food combination and proportioning processes, and aiding patient recovery. It also facilitates the standardization of food collection procedures and allows for comparative analysis with other relevant results. Attached Figure Description

[0187] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0188] One person can operate this intelligent high-precision weighing device for dietary ingredients for children with diabetes.

[0189] Before operating this intelligent high-precision weighing device for dietary ingredients for children with diabetes, it is necessary to confirm that the patient is a child with diabetes and to check whether the device is operating normally: whether the display screen is clear, whether the battery is sufficient, and whether all parts are functioning properly. Remove the intelligent high-precision weighing device and check whether all components are complete (e.g., ...). Figure 1 Press and hold the large central switch on the weighing mainboard (e.g., ...). Figure 10 To start the device, press the bottom selection button on the time control knob to choose whether to change the preset time (smaller text at the top) or the real-time time (larger text at the bottom). The time will flash during selection; if the button remains pressed for more than 2 seconds, the selection is confirmed. Then press the button with the "+" sign next to the time display screen (e.g., ...). Figure 4 (Above) Increase the time to the pre-prepared meal time that needs to be reminded. If the button increases the time too much, press the button with "-" (e.g., Figure 4 (Next) Reduce the time to the required amount and check the time display screen (e.g.) Figure 2 Are the numbers displayed on the scale clear? Select the weighing unit as grams and the no-tare mode, and place a large tray (such as...) on the weighing pan. Figure 5 Check the weight display (e.g.) Figure 7 Check if the numbers displayed on the screen are accurate and clear. For example, if the actual weight of the large tray is 20 grams, the weight display should show 20.00. If it is unclear, check the cause. If it is caused by screen aging, replace the screen (e.g., ...). Figure 7 If the battery is low, replace it or charge it promptly (e.g., ...). Figure 9 , Figure 11 , Figure 12 After the inspection is passed, press and hold the main switch to turn off the device and enter the actual project operation test.

[0190] First, such as Figure 16The intelligent high-precision weighing device for dietary ingredients for children with diabetes, as shown in this invention, implements the input of basic patient information, including age, height, weight, and occupation. Using the example from the background section, on the application interface equipped with an input method, the user inputs: age: 8 years old, height: 150cm, weight: 46kg, occupation: student. The software automatically calculates: BMI: 20.44, obesity rate: 2.22%, obesity level: normal, work intensity: moderate, daily energy requirement: 1640-1680 kcal, daily nutritional ratio: protein: 49.2g-58.8g, fat: 36.44g-56g, carbohydrates: 225.5g-273g. The device checks whether each indicator is displayed and whether the results are accurate. If inaccurate, the cause is checked, and the information is manually re-entered and corrected. If necessary, the device is shut down and restarted. If the displayed results are complete and accurate, a preset time reminder is given, and the user proceeds to the recipe selection step. Generally, this step involves re-entering the weight value weekly, but the user can also change the weight value and other changed indicators at any time.

[0191] In the ingredient table on the recipe display screen, the user first observes whether the displayed elements are complete and accurate, including the day of the week in the header row, the five main eating time zones on the left, the first row category, the number of food exchange portions, ingredient name, equivalent weight (grams), edible weight (grams), dish name, and completion. In the category column, breakfast includes pre-meal vegetables, water, dairy, fruit, vegetables, meat, eggs, beans, whole grains, oil, seasonings, and nuts; snacks include fruit and whole grains; lunch includes fruit, vegetables, meat, eggs, beans, whole grains, oil, seasonings, and nuts; dinner includes fruit, vegetables, meat, eggs, beans, whole grains, oil, seasonings, and nuts. The user checks whether the numbers can be manually changed to increase or decrease each food exchange portion, whether recommended ingredient names are displayed, and whether adding ingredients to a category can be done by double-clicking a row. If the information is incomplete, inaccurate, or rows cannot be added smoothly, the user checks the cause and fixes it; if everything is complete, accurate, and rows can be added smoothly, the user checks the sensitivity of ingredient selection.

[0192] In the food exchange portion count section, users check whether the sum of the food exchange portions automatically recommended by the software system is within the total range, and whether the main food categories in the five dining areas have recommended values. Any food item with a recommended value will have a bright blue circle appear next to it in the "Completed" column.

[0193] Randomly check one of the categories. For example, select the lunch vegetable section and choose cabbage. The software system will automatically display the edible weight (grams) as 100 based on the previous 0.2 servings and the equivalent weight (grams) value of 500. If no data is displayed, or the display is incorrect or unclear, check the cause and fix it; if the check passes, proceed to the next step. Under normal circumstances, assuming no malfunctions, this series of equipment checks should be performed once a week.

[0194] Doctors, nutritionists, or users can select all categories of ingredients on a mobile app or recipe display screen for later use. The system will also automatically save the recipe table for that date via a USB interface (e.g.,...). Figure 9 , Figure 12 The files can be exported via Bluetooth for later use, such as backtracking.

[0195] Regardless of whether the intelligent high-precision weighing device for children's diabetic dietary ingredients is powered off or on, it will receive an alarm sound indicating that the meal preparation time has arrived. Upon hearing the "beep" sound, the user presses the sun-shaped speaker (e.g., Figure 3 The alarm sound can be silenced by either a physical alarm or a mobile app, after which the weighing of ingredients can proceed. For example, if a user is weighing milk in the morning, they will use a measuring cup. The user first sets the weighing display to zero, places the clean measuring cup on the weighing platform, and presses the unit selection button (e.g., ...). Figure 13 Select the unit as g, then press the "Remove Weighing Carrier (Tare, ~o~)" key (e.g.) Figure 14 Zero the scale, slowly pour in milk until the target weight is reached. The display will show 200.00 grams, and an alarm will sound once. The user can touch the bright blue circle with their finger to turn it into a dark blue ring, confirming the completion of the weighing step for this ingredient, and then proceed to the next step of weighing the watermelon. After removing the measuring cup and milk, clean the weighing platform, zero the display again, and then put the watermelon in. When the target weight is reached, the display will show 125.00 grams, and an alarm will sound once. The user can touch the bright blue circle with their finger to turn it into a dark blue ring, confirming the completion of the weighing step for this ingredient. If the weighing is incorrect, you can still proceed to the next step, but the button will still show a bright blue circle. The user can complete the weighing of all ingredients in this way. The system will also automatically save a table of weighing completion for this recipe on that date, which can be accessed via USB interface (e.g., Figure 9 , Figure 12 The files can be exported via Bluetooth for later use, such as backtracking.

[0196] Finally, the user gathers all the ingredients and prepares the meal according to the different colors representing different dishes.

[0197] This invention is not limited to the embodiments described above. Without departing from the spirit of this invention, those skilled in the art can use computer code to program the calculation process, making it more comprehensive, and can also connect to the internet for information processing, modifying aspects such as occupational types, ingredient contents, construction techniques, and dimensions. Therefore, the scope of the claims of this invention is not limited to the scope of the detailed description, but rather to the following claims and their technical concept.
