Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of nutritional management tools for hemodialysis patients, and in particular to a rotating diet guidance tray for nutritional management of dialysis patients. Background Technology
[0002] Hemodialysis patients must strictly adhere to the "three highs and one low" dietary restrictions (high potassium, high phosphorus, high water, and low protein). Studies have shown that:
[0003] High-potassium foods (such as bananas and potatoes) can trigger fatal arrhythmias; serum potassium levels >5.5 mmol / L can increase the risk of death in dialysis patients by 30%.
[0004] High-phosphorus foods (such as dairy products and organ meats) lead to vascular calcification, and approximately 60% of dialysis patients die from cardiovascular complications.
[0005] Excessive water retention (daily increase > 2-3% of dry body weight) can easily trigger acute pulmonary edema, requiring emergency ultrafiltration treatment.
[0006] Protein intake imbalance: Hypoproteinemia increases the risk of infection, but excessive protein exacerbates azotemia.
[0007] However, patients generally lack nutritional knowledge and have difficulty remembering food components. Traditional paper-based dietary guidelines are cumbersome to operate and difficult to dynamically match. When a patient consumes a certain type of high-risk food, it is inconvenient to match it with low-risk compensating foods. Therefore, a rotating dietary guidance disk for dialysis patient nutrition management was designed to solve the above problems. Utility Model Content
[0008] To address the shortcomings of existing technologies, this utility model provides a rotating dietary guidance tray for dialysis patient nutrition management. When a patient ingests a certain type of high-risk food, it is convenient to quickly and easily match low-risk foods to compensate, ensuring the patient's dietary health and making it highly practical.
[0009] To solve the above-mentioned technical problems, the present invention proposes the following technical solution:
[0010] A rotating dietary guidance tray for dialysis patient nutrition management includes a base plate, a fixed shaft, a first turntable, a second turntable, a third turntable, a fourth turntable, and fan-shaped grooves. A fixed shaft is fixedly mounted at the center of the upper surface of the base plate. The first turntable is rotatably mounted on the fixed shaft via bearings. A second turntable is rotatably mounted on the outer surface of the first turntable via bearings. A third turntable is rotatably mounted on the outer surface of the second turntable via bearings. A fourth turntable is rotatably mounted on the outer surface of the third turntable via bearings. Each of the eight fan-shaped grooves on the first, second, third, and fourth turntables has markings indicating high moisture, low moisture, high potassium, low potassium, high phosphorus, low phosphorus, high protein, and low protein, respectively.
[0011] Furthermore, the first, second, third, and fourth turntables can correspond to the names of fruits, staple foods, meats, and vegetables, respectively.
[0012] Furthermore, the radii of the eight sector slots on the first, second, third, and fourth turntables are all the same.
[0013] Furthermore, green safety labels are provided in the sector-shaped slots corresponding to low moisture, low potassium, low phosphorus, and high protein on the first, second, third, and fourth turntables.
[0014] Furthermore, red warning signs are provided in the sector-shaped slots corresponding to high moisture, high potassium, high phosphorus, and low protein on the first, second, third, and fourth turntables.
[0015] Furthermore, the green safety sign and the red warning sign have different shapes, with the green safety sign and the red warning sign respectively corresponding to the shapes of "△" or "○".
[0016] Furthermore, a magnetic strip is embedded on the outer side of the upper surface of the base plate, and a metal strip is embedded in the center below the fan-shaped grooves of the first, second, third, and fourth turntables.
[0017] Furthermore, the width of the magnetic strip is equal to the width of the metal strip, and the magnetic strip is made of neodymium iron boron magnet material, while the metal strip is made of stainless steel material that can be magnetically attracted.
[0018] Furthermore, a reference feeding line is electroplated on the outer side of the upper surface of the magnetic strip.
[0019] As can be seen from the above technical solution, the beneficial effects of this utility model are:
[0020] 1. This utility model is equipped with a first turntable, a second turntable, a third turntable, a fourth turntable, and a fan-shaped groove. When a patient selects a high-risk food that is high in potassium, phosphorus, water, and low in protein, the other three turntables are rotated so that the other three turntables correspond to low-risk foods, thereby ensuring a balanced diet for the patient.
[0021] 2. This utility model features green safety labels and red warning labels, which make it easier for patients to choose food more intuitively. When a patient chooses a food marked with a high-risk red warning label, they need to choose a food marked with a green safety label from the other three food categories to ensure the health of the patient's diet. In addition, the green safety labels and red warning labels have different shapes, which makes it easier for colorblind patients to choose food based on the shapes.
[0022] 3. This utility model incorporates magnetic strips and metal strips. When a patient rotates the food, they select the desired food by turning the first, second, third, and fourth turntables. The magnetic strips attract the metal strips at the bottom of the fan-shaped grooves on the first, second, third, and fourth turntables, thus positioning the rotation of these turntables. This ensures that the food selected in the fan-shaped grooves on the first, second, third, and fourth turntables aligns with the reference feeding line, facilitating food retrieval for the user.

[0033] See Figures 1-4 A rotating dietary guidance tray for dialysis patient nutrition management includes a base plate 1, a fixed shaft 2, a first rotating plate 3, a second rotating plate 4, a third rotating plate 5, a fourth rotating plate 6, and fan-shaped grooves 7. The fixed shaft 2 is fixedly installed in the center of the upper surface of the base plate 1. The first rotating plate 3 is rotatably mounted on the fixed shaft 2 via bearings. The second rotating plate 4 is rotatably mounted on the outer surface of the first rotating plate 3 via bearings. The third rotating plate 5 is mounted on the outer surface of the second rotating plate 4 via bearings. The fourth rotating plate 6 is rotatably mounted on the outer surface of the third rotating plate 5 via bearings. Each of the eight fan-shaped grooves 7 on the first rotating plate 3, the second rotating plate 4, the third rotating plate 5, and the fourth rotating plate 6 is marked with labels indicating high moisture, low moisture, high potassium, low potassium, high phosphorus, low phosphorus, high protein, and low protein, respectively.
[0034] In this embodiment, the first turntable 3, the second turntable 4, the third turntable 5, and the fourth turntable 6 can correspond to the names of fruits, staple foods, meats, and vegetables, respectively. This allows the eight fan-shaped slots 7 within the first turntable 3, the second turntable 4, the third turntable 5, and the fourth turntable 6 to correspond to the high-moisture, low-moisture, high-potassium, low-potassium, high-phosphorus, low-phosphorus, high-protein, and low-protein fruits, staple foods, meats, and vegetables, respectively.
[0035] Specifically, the entire device consists of four rotating trays, corresponding to the fruit, staple food, meat, and vegetable layers, respectively. Each tray is divided into eight equal areas. Taking the fruit layer as an example, these eight areas correspond to the eight categories: high-water-content fruits, high-potassium fruits, high-phosphorus fruits, low-protein fruits, low-water-content fruits, low-potassium fruits, low-phosphorus fruits, and high-protein fruits. The other three trays (staple food, meat, and vegetable layers) are also divided into areas according to these eight categories.
[0036] By setting up a first turntable 3, a second turntable 4, a third turntable 5, a fourth turntable 6, and a sector groove 7, when a patient selects a high-risk food that is high in potassium, high in phosphorus, low in phosphorus, high in water, and low in protein, the other three turntables are rotated so that the other three turntables correspond to low-risk foods, thus ensuring a balanced diet for the patient.
[0037] For example, when a patient wants to eat high-potassium staple foods (such as mixed grain rice),
[0038] 1. Rotate the second turntable 4 so that the mixed grain rice is aligned with the reference feeding line 101 (red high potassium area).
[0039] 2. Rotate the first layer until it points towards the low-potassium fruit (such as apple) and aligns it with the reference feeding line 101.
[0040] 3. Rotate the third layer until it aligns with the reference feeding line 101 for low-potassium meats (such as chicken breast).
[0041] 4. Rotate the fourth layer to align the low-potassium vegetables (such as cucumbers) with the reference feeding line 101.
[0042] In this embodiment, the radii of the eight sector slots 7 on the first turntable 3, the second turntable 4, the third turntable 5, and the fourth turntable 6 are all the same.
[0043] In this embodiment, green safety signs 8 are provided in the sector-shaped grooves 7 corresponding to low moisture, low potassium, low phosphorus, and high protein on the first turntable 3, the second turntable 4, the third turntable 5, and the fourth turntable 6.
[0044] In this embodiment, red warning signs 9 are provided in the sector-shaped grooves 7 corresponding to high moisture, high potassium, high phosphorus and low protein on the first turntable 3, the second turntable 4, the third turntable 5 and the fourth turntable 6.
[0045] In this embodiment, the green safety sign 8 and the red warning sign 9 have different shapes. The green safety sign 8 and the red warning sign 9 are respectively in the shape of "△" or "○", where "△" indicates safety and "○" indicates danger.
[0046] Specifically, in another possible embodiment, red and green labels are used for the identification of each area. Red warning label 9 indicates high-risk food areas, such as those high in potassium, phosphorus, and water, which may have adverse effects on hemodialysis patients; green safety label 8 indicates low-risk food areas, namely those with relatively safe foods such as low in potassium, phosphorus, and water. This clear color contrast makes it easier for elderly patients and those with low levels of education to identify the food.
[0047] In this embodiment, a magnetic strip 10 is embedded on the outer side of the upper surface of the base plate 1, and a metal strip 11 is embedded in the center below the fan-shaped groove 7 of the first turntable 3, the second turntable 4, the third turntable 5 and the fourth turntable 6.
[0048] In this embodiment, the width of the magnetic strip 10 is equal to the width of the metal strip 11, and the magnetic strip 10 is made of neodymium iron boron magnet material, while the metal strip 11 is made of stainless steel material that can be magnetically attracted.
[0049] In this embodiment, a reference feeding line 101 is electroplated on the outer side of the upper surface of the magnetic strip 10, which facilitates the selection of food according to the fan-shaped groove 7 pointed to by the reference feeding line 101.
[0050] By incorporating magnetic strips 10 and metal strips 11, when a patient rotates the food, they can select the food they wish to eat by rotating the first turntable 3, second turntable 4, third turntable 5, and fourth turntable 6. The magnetic strips 10 attract the metal strips 11 at the bottom of the fan-shaped grooves 7 of the first turntable 3, second turntable 4, third turntable 5, and fourth turntable 6, thus positioning the rotational positions of the first turntable 3, second turntable 4, third turntable 5, and fourth turntable 6. This ensures that the food selected by the fan-shaped grooves 7 on the first turntable 3, second turntable 4, third turntable 5, and fourth turntable 6 is aligned with the reference feeding line 101, making it convenient for the user to pick up the food.
[0051] Instructions for use: When a patient consumes food with a high content of a certain component, such as a high-moisture staple food (like porridge), the turntable can be rotated to move the other three layers and the outermost turntable to the corresponding low-moisture fruit, meat, and vegetable areas, thereby achieving a reasonable dietary balance and avoiding the intake of too much or too little of a certain nutrient.
[0052] Its working principle is as follows: When the patient selects a certain type of "high-content food" → rotate that layer to align the food with the baseline → the other three layers automatically rotate to the "low-content food area" → forming a balanced combination of nutrients. The food areas are brightly colored red and green, making them easy for elderly patients and those with low literacy levels to identify, ensuring the feasibility of the nutrition plan.
[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
