Description

Technical Field

[0001] This utility model relates to a diet calculation panel for kidney disease, belonging to the field of medical auxiliary equipment technology. Background Technology

[0002] Chronic kidney disease (CHD), characterized by progressive decline in kidney function, requires a long-term approach combining medication and dietary management. Clinical studies have shown that the intake of protein, potassium, and sodium in the diet of kidney disease patients directly affects the metabolic burden on the kidneys. Excessive protein intake can increase glomerular filtration pressure, potassium accumulation can easily lead to hyperkalemia and arrhythmia, and excessive sodium intake can induce water and sodium retention and hypertension, further worsening kidney function. At the same time, changes in a patient's weight, such as rapid weight gain or loss in a short period, can directly reflect the state of fluid metabolism and are an important basis for adjusting the diet plan. Therefore, precise control of food intake, nutrient content, and weight changes is a core requirement for kidney disease patients to slow the progression of the disease.

[0003] Existing tools often focus on a single function, such as calculating nutrients or measuring weight. Patients need to carry multiple items, including paper documents, electronic devices, and measuring tools. They also need to switch between different tools, making the operation process complicated. This is especially unsuitable for elderly patients with limited mobility or memory loss, and it is difficult to meet the needs of one-stop dietary management. Paper tools rely on manual calculations, while electronic tools rely on equipment operation. Furthermore, some simple tools, such as dials without positioning structures, lack precise reading guidance, and the pointer is prone to slippage, leading to reading errors. For example, 250mg potassium may be misread as 350mg potassium, which is particularly unfriendly to patients with poor vision and further reduces the accuracy of dietary control. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a diet calculation panel for kidney disease.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A diet calculation panel for kidney disease includes a base, a connecting rod inserted into the upper side of the base, a fixed plate fixedly connected to the end of the connecting rod, and a food intake plate, a nutrient intake plate, and a periodic weight plate magnetically connected sequentially from the outside to the inside on one side of the fixed plate. A click pointer assembly is provided in the middle of the fixed plate, and a display component is provided on one side of the base.

[0006] Through the above technical solution, the base serves as the foundation of the device, providing support. The plug-in rod is vertically fixed to the upper side of the base via a plug-in method, and the fixed plate at its end is the core load-bearing structure. The food intake plate, nutrient intake plate, and periodic weight plate are magnetically attracted to one side of the fixed plate and are arranged radially from the outside to the inside. They can rotate around the axis of the fixed plate to adjust the corresponding scale position. The click pointer component in the middle of the fixed plate is used to accurately point to the scale information of each plate, and the display component on one side of the base is used to assist in recording and displaying diet and weight-related data. All structures work together to realize the functions of diet calculation and data management.

[0007] The plug-in and magnetic connections simplify the assembly and disassembly process, making it easy to store and carry. The multi-layered magnetic arrangement of the trays ensures the flexibility of independent adjustment of each tray while preventing the trays from falling off or becoming misaligned, thus improving operational stability. It integrates three core functions: food intake, nutrient control, and weight tracking. No additional tools are required, meeting the one-stop dietary management needs of kidney disease patients and reducing operational complexity.

[0008] Preferably, the food intake plate uses at least three types of intake plates: grains, vegetables, and meat.

[0009] Through the above technical solution, the food intake plate is subdivided according to food category, including at least three independent sub-plates: grains, vegetables, and meats. The surface of each sub-plate is marked with the recommended intake of the corresponding food, such as grains in grams and vegetables in servings. By rotating the sub-plate, the intake scale of the target food can be aligned with the pointer, so as to quickly locate the intake dose of a specific food.

[0010] The sub-plates are divided into food categories to avoid confusion caused by mixed scales for different foods. This meets the differentiated management needs of kidney disease patients for controlling carbohydrates in grains, potassium in vegetables, and protein in meats. It specifically covers three core food categories, eliminating the need for additional redundant plates. It balances comprehensive functionality with a simple structure, allowing patients to directly match their daily diet and improving operational efficiency.

[0011] Preferably, the nutrient intake chart uses at least three intake charts: protein, potassium, and sodium.

[0012] Through the above technical solution, the nutrient intake panel is subdivided according to the key nutrients for kidney disease patients, including at least three independent sub-panels: protein, potassium, and sodium. Each sub-panel is marked with the daily safe intake range of the corresponding nutrient, such as protein in g / kg body weight and potassium / sodium in mg / day. Rotating the sub-panel can align the actual nutrient dosage required by the patient with the pointer. At the same time, it can be linked with the food intake panel, such as adjusting the protein plate scale according to the amount of meat consumed.

[0013] Focusing on three key nutrients—protein, potassium, and sodium—that increase the metabolic burden on the kidneys, this product precisely matches the dietary restrictions for kidney disease patients, preventing the condition from worsening due to excessive nutrient intake. Each nutrient is independently regulated and can be linked with the food plate to achieve two-way matching of food and nutrients, helping patients quickly calculate what and how much to eat and lowering the professional threshold for dietary calculation.

[0014] Preferably, the number of the cycle weight plates is four, each corresponding to a weight plate for one of the four cycles.

[0015] The above technical solution sets up four independent sub-discs for the periodic weight display, each corresponding to one of the four consecutive periods, such as one week. Each sub-disc is marked with a weight recording scale, such as kg. By rotating the sub-disc, the actual weight value of each period can be aligned with the pointer. The four sub-discs are distributed around the fixed disk, making it easy to switch between and view the weight data of different periods.

[0016] The four-cycle weight pan can completely record the weight change trend within a month, helping patients and medical staff to verify the rationality of the diet plan through weight fluctuations. If there is an abnormal decrease or increase in weight, the diet can be adjusted in time. The periodic data storage avoids the scale crowding caused by recording multiple cycles of data on a single pan, and the magnetic adsorption and rotatable structure makes it easy to quickly compare the weight of different cycles, improving the intuitiveness of data tracking.

[0017] Preferably, the click pointer assembly includes a spring-loaded limiting ring, which is disposed in the middle of the fixed plate. A guide rod is inserted into the middle of the spring-loaded limiting ring. A paddle matching the spring-loaded limiting ring is disposed on the outer side of the guide rod. A fixing plate is disposed at one end of the guide rod. A pointer is disposed on one side of the fixing plate. A limiting nut is threaded onto the outer side of the guide rod. A knob is disposed at the other end of the guide rod. A magnifying lens is disposed on one side of the pointer and at a position opposite to the periodic weight plate.

[0018] With the above technical solution, the spring-loaded limiting ring is fixed in the middle of the fixed plate, and the guide rod passes through the center of the spring-loaded limiting ring. The paddle on the outside of the guide rod cooperates with the elastic protrusion of the spring-loaded limiting ring. When the knob is rotated, the paddle squeezes the elastic protrusion to produce a clicking sound, achieving precise positioning for each rotation of the scale. The fixing plate at one end of the guide rod is connected to the pointer, and the pointer rotates synchronously with the guide rod to point to each scale. The limiting nut is threaded onto the outside of the guide rod to lock the position of the guide rod and prevent accidental displacement. The magnifying convex lens on one side of the pointer is directly opposite the scale of the periodic weight plate, which can magnify the fine scale values.

[0019] The combination of click feedback and spring-loaded limiting structure ensures that the pointer does not deviate when pointing to the scale, solving the reading error problem caused by the looseness of traditional pointers and improving data accuracy; The magnifying convex lens can clearly display the fine scale of the cycle weight dial, making it suitable for elderly patients or people with poor vision; the limiting nut can fix the pointer position, making it easy to view or record data for a long time, and the operation feels stable.

[0020] Preferably, the display component includes a drawer, which is slidably connected to one side of the base via a slide rail. The drawer contains several textured magnets. A daily magnetic plate is provided on one side of the base, and a periodic magnetic plate is provided on the upper side of the base.

[0021] Through the above technical solution, the drawer is slidably connected to one side of the base via a slide rail, and the interior is used to store several texture magnets, such as magnetic patches that label dietary information such as breakfast staple food and dinner protein; the daily magnetic plate on one side of the base can attract texture magnets to record the daily diet plan or actual intake; the periodic magnetic plate on the upper side of the base also attracts texture magnets through magnetic force to summarize dietary data from multiple days to form a periodic dietary record.

[0022] The drawer allows for centralized storage of the sticker magnets, preventing parts from getting lost, and the sliding rail structure makes them easy to pull out and use. The daily and periodic magnetic board partition design allows for separate recording of short-term and long-term dietary data. The data is clearly layered, making it easy for patients to review their dietary patterns. The sticker magnets can be reused, eliminating the need for paper records. This design is both environmentally friendly and allows for flexible adjustment of dietary information to adapt to changes in dietary plans for different dates.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a food intake plate, a nutrient intake plate, and a periodic weight plate arranged sequentially from the outside to the inside along a fixed plate. Each plate is independent and does not overlap, which not only avoids confusion of scales but also enables simultaneous viewing of multi-dimensional data, allowing patients to simultaneously monitor food intake, nutrient control, and weight changes, thereby improving the efficiency of dietary management.

[0024] This invention integrates a click pointer component and a display component, enabling the reading, recording, and display of dietary data without the need for additional tools. This simplifies the operation process, lowers the barrier to entry for kidney disease patients (especially elderly patients), and helps patients manage their diet independently.

[0025] In this invention, the spring-loaded limiting ring and the paddle work together to produce a "click" sound, achieving precise positioning of the pointer and avoiding the scale reading errors caused by the easy slippage of traditional pointers. This ensures accurate reading of data such as food intake, nutrient content, and weight, providing reliable data support for patients' dietary management. The magnifying lens on one side of the pointer can magnify the scale of the periodic weight dial, which is suitable for elderly patients with poor vision, improves the convenience and accuracy of reading the scale, and avoids errors in recording weight data due to vision problems. The limit nut locks the guide rod position, preventing accidental pointer displacement during patient operation and ensuring the stability of data recording; the knob allows patients to easily rotate the guide rod to adjust the pointer position, making operation effortless and convenient, and improving the user experience.

[0037] In this embodiment, a patient weighing 60kg and in stage 3 chronic kidney disease is used as an example to illustrate the specific usage process of the calculation panel: Weight and Nutrient Benchmarks Rotate the first sub-disc of the cycle weight plate 6 until the 60kg mark is aligned with the tip of pointer 11; Rotate the protein disc on nutrient intake disc 5 and align the 0.8g / kg body weight / day (48g / day) mark with the pointer according to the scale corresponding to 60kg body weight. Rotate the potassium and sodium discs to align the upper limit marks of 2500 mg / day and 2000 mg / day with the pointers to complete the baseline setting.

[0038] Food intake matching Grain intake: Rotate the grain plate on food intake plate 4, select the "250g rice" mark and align it with the pointer to correspond to approximately 7.5g of protein; Meat intake: Rotate the meat tray and align the 60g lean meat mark with the pointer, which corresponds to approximately 8.4g of protein; Vegetable intake: Rotate the vegetable tray and select 350g of low-potassium vegetables. Align the mark with the pointer to get approximately 525mg of potassium. Real-time verification: The cumulative scale of the protein plate is 7.5 + 8.4 = 15.9g, which does not exceed the upper limit of 48g. The cumulative scale of the potassium plate is 525mg, which does not exceed the upper limit of 2500mg. It is confirmed that the requirements are met.

[0039] Dietary records and summaries Take out the corresponding texture magnets 16 from drawer 15: Breakfast: 250g of cereal, Lunch: 60g of meat, Dinner: 350g of vegetables, and attach them to the corresponding time period area of ​​the daily magnetic board 17. At the end of each week, the sticker magnets on the daily magnetic board are collected and transferred to the corresponding week area of ​​the cycle magnetic board 18. For example, the area of ​​week 1 will attract all the food stickers of that week. At the same time, rotate the sub-board of week 2 of the cycle weight plate to record the weight of that week, such as 60.2kg, and complete the cycle tracking.

[0040] Pointer locking and tick reading After adjusting each dial, tighten the limit nut 12 clockwise until the nut is flush with the spring limit ring 7 to lock the pointer position and prevent accidental displacement. When reading the scale of the cycle weight plate, the 60.2kg mark can be clearly seen through the magnifying convex lens 14 on the pointer, avoiding reading errors caused by the small scale.
