Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a measuring tool for quantifying the postoperative diet of patients undergoing gastrectomy for gastric cancer. Background Technology

[0002] Gastric cancer ranks fifth in incidence and fourth in mortality globally, with even higher rates in my country, seriously threatening the health and safety of the Chinese people. With the continuous development of medical technology and the increasing health awareness of the Chinese population in recent years, the survival and recovery rates after surgery have been improving year by year. However, gastrectomy for gastric cancer alters the original physiological anatomy of the gastrointestinal tract, leading to significant postoperative complaints such as reflux and bloating. Therefore, developing individualized dietary plans based on each patient's unique needs is crucial for improving their postoperative quality of life.

[0003] Existing measurement tools for postoperative food intake of gastrectomy patients are relatively simple in structure. They generally use a single measuring cup to measure the required amount of food. There is no special food measurement device for gastric cancer surgery patients. Postoperative food intake of gastric cancer patients mainly relies on the patient's own feelings, without specific quantitative measures and scientific evaluation. At the same time, existing measurement tools lack a sealed protective structure for storing measuring cups, which can easily breed bacteria and affect safe use.

[0004] Therefore, how to provide a measurement tool for quantifying the postoperative diet of patients undergoing gastrectomy for gastric cancer is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0015] As a further preferred embodiment of the present invention: both the germicidal lamp and the annular light strip are configured as ultraviolet lamps, and the annular light strip is disposed outside the limiting groove.

[0016] The beneficial effects of this invention are: 1. This is a measuring tool for postoperative dietary quantity measurement for patients undergoing gastrectomy for gastric cancer. It consists of a base, a measuring cup, and a control panel. The control panel includes a display screen and function buttons. The function buttons are: liquid button, solid button, 3 / 4 full button, 6 / 8 / 9 full button, next level button, food intake button, and discomfort button. Pressing the "liquid" or "solid" function button on the control panel inputs the food type to the MCU control module. Within 15 minutes after eating, the patient presses the "3 / 4 full / 6 / 8 / 9 full / discomfort" feedback button based on their own feeling, and then presses the "next level" button. The display screen immediately shows the next food intake and time (e.g., "next food intake 60ml, time 14:30"). If "discomfort" is pressed, the display screen prompts "pause eating and consult medical staff." This tool allows users to select the appropriate time and amount for the next meal based on their different satiety levels, facilitating the development of a more scientific and reasonable meal plan.

[0017] 2. This is a measuring tool for quantifying postoperative food intake in patients undergoing gastrectomy for gastric cancer. It includes a bubble level and a support adjustment assembly. The support adjustment assembly consists of a threaded sleeve, an anti-slip base, a lead screw, a ball head, and a ball head sleeve. The bubble level allows observation of whether the base is level. If the bubble deviates from the center, rotating the support adjustment assembly (threaded sleeve) at the bottom of the base allows for fine-tuning of the height through the threaded transmission between the lead screw and the threaded sleeve until the bubble is centered. The ball head and ball head sleeve in the support adjustment assembly are movably connected, adapting to different platform tilt angles. Combined with the real-time monitoring of the bubble level, this ensures the measuring cup is level, avoiding measurement errors caused by tilt and ensuring the effectiveness of the measuring cup.

[0018] 3. This is a measuring tool for measuring the postoperative diet of patients undergoing gastrectomy for gastric cancer. A protective cover is installed on the outside of the measuring cup to effectively protect it. The bottom of the protective cover is equipped with a damping rod, a limiting plate, and a limiting groove that work together. The limiting groove engages with the top of the measuring cup to limit and press down on the top, improving the stability and sealing of the measuring cup. Additionally, a germicidal lamp and a ring-shaped light strip are installed at the bottom of the limiting plate to sterilize the inside and outside of the stored measuring cup, preventing bacterial growth and enhancing safe use.

[0019] 4. This is a measuring tool for quantifying the postoperative diet of patients undergoing gastrectomy for gastric cancer. It features a locking block and sealing ring at the bottom of a protective cover, and a groove, embedding groove, and locking slot on the inner wall of the recess. A support spring and support ring are installed at the bottom of the inner wall of the groove, and a sealing groove is provided at the top of the support ring for coordinated use. Since the locking block matches the inner diameter of the embedding groove, sliding groove, and locking slot, pressing down on the protective cover during use pushes the support ring and support spring downwards, separating the locking block from the locking slot at the bottom of the protective cover. Simultaneously rotating the protective cover aligns the locking block with the embedding groove, and then lifting the protective cover upwards allows for quick assembly and disassembly, facilitating better work and use.

Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0031] Please see Figures 1 to 9 In this embodiment: a measuring tool for quantifying the postoperative diet of patients undergoing gastrectomy for gastric cancer includes a base 1, a control panel 2 fixedly installed on one side of the base 1, function buttons 3 on the control panel 2, a display screen 4 on the control panel 2, a bubble level 5 installed on the top of the base 1 for easy observation of whether the base 1 is level, a support adjustment component 6 installed at the bottom of the base 1 for adjusting the level of the base 1, a groove 7 on the top of the base 1, a placement seat 8 fixedly installed in the center of the groove 7, a measuring cup 9 placed on the placement seat 8 to improve the stability of the measuring cup 9, and a protective cover 16 installed on the top of the base 1 to effectively protect the measuring cup 9 and prevent dust and impurities from easily adhering to the measuring cup 9 and causing contamination.

[0032] refer to Figure 1 and Figure 9 As shown, the control panel 2 is equipped with a battery module, a charging module, a voltage regulator module, and an MCU control module. The function buttons 3 consist of liquid buttons, solid buttons, 3 / 4 full buttons, 6 / 4 full buttons, 8 / 4 full buttons, next level buttons, food intake buttons, and discomfort buttons. By setting multiple function buttons 3, users can easily select different types of food and satiety levels, allowing postoperative patients or their families to independently complete food measurement and planning without professional knowledge.

[0033] refer to Figure 1 , Figure 7 and Figure 8As shown, the support adjustment assembly 6 includes a threaded sleeve 601, an anti-slip seat 602 installed at the bottom of the threaded sleeve 601, a lead screw 603 inside the threaded sleeve 601, a ball head 604 fixedly connected to one end of the lead screw 603, and a ball head sleeve 605 fitted over the ball head 604. The bottom of the threaded sleeve 601 is rotatably connected to the anti-slip seat 602 via a shaft. The threaded sleeve 601 and the lead screw 603 are threadedly rotatably connected, and the ball head 604 and the ball head sleeve 605 are movably connected. The ball head sleeve 605 is fixedly installed at the bottom of the base 1. By installing a bubble level 5 on the top of the base 1, it is possible to observe whether the base 1 is in a horizontal state. When the base 1 is tilted, by rotating the threaded sleeve 601 to adjust the lead screw 603, the base 1 can be raised and lowered finely around its perimeter to make the base 1 horizontal, thereby improving the measurement accuracy of the measuring cup 9.

[0034] refer to Figure 2 and Figure 3 As shown, the placement seat 8 has a placement groove inside. The outer diameter of the bottom of the measuring cup 9 is matched with the inner diameter of the placement groove. The outer walls of the measuring cup 9 are respectively provided with graduation lines suitable for liquids and solids. The placement groove limits the bottom of the measuring cup 9, which can improve the placement stability of the measuring cup 9. At the same time, the graduation lines on both sides of the outer walls of the measuring cup 9 are suitable for liquids and solids, making it convenient for users to observe the amount of liquid or solid placed.

[0035] refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a sliding groove 10 is provided on the inner wall of the groove 7, and an embedding groove 11 is provided on the top of the sliding groove 10. The embedding groove 11 penetrates the top of the base 1. A locking groove 12 is provided on the top of the sliding groove 10. There are four sets of sliding grooves 10, embedding grooves 11 and locking grooves 12, which are symmetrically distributed in a ring on the inner wall of the groove 7. A locking block 17 is fixedly installed on the outer side of the bottom of the protective cover 16. A sealing ring 18 is provided at the bottom of the protective cover 16. The outer diameter of the locking block 17 is adapted to the inner diameter of the embedding groove 11, the sliding groove 10 and the locking groove 12. The outer diameter of the bottom of the protective cover 16 is adapted to the inner diameter of the groove 7. By setting the outer diameter of the bottom of the protective cover 16 to be adapted to the inner diameter of the groove 7, and the outer diameter of the locking block 17 to be adapted to the inner diameter of the embedding groove 11, the sliding groove 10 and the locking groove 12, the locking block 17 at the bottom of the protective cover 16 is inserted into the embedding groove 11, and then the protective cover 16 is rotated to quickly fix and install the protective cover 16.

[0036] refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, several sets of support springs 13 are fixedly installed at the bottom of the inner wall of the groove 7. The support springs 13 are symmetrically fixedly installed in a ring inside the groove 7. A support ring 14 is fixedly installed on the top of the support springs 13. A sealing groove 15 is provided on the support ring 14. The inner diameter of the sealing groove 15 is adapted to the outer diameter of the sealing ring 18. The sealing ring 18 and the sealing groove 15 are movably sealed together. By setting the sealing ring 18 and the sealing groove 15 to be movably sealed together, the protective sealing performance of the protective cover 16 to the measuring cup 9 can be improved. At the same time, the support springs 13 support the support ring 14 and the protective cover 16 upward, which will cause the locking block 17 on the outer side of the outer wall of the protective cover 16 to engage and lock with the locking groove 12, preventing the protective cover 16 from accidentally rotating and falling off.

[0037] refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a damping rod 19 is fixedly installed on the top of the inner wall of the protective cover 16. A limiting plate 20 is fixedly installed on one end of the damping rod 19. A limiting groove 21 is opened at the bottom of the limiting plate 20. A germicidal lamp 22 is fixedly installed at the bottom of the limiting plate 20. A ring-shaped light strip 23 is fixedly installed at the bottom of the limiting plate 20. The inner diameter of the limiting groove 21 is adapted to the outer diameter of the cup opening at the top of the measuring cup 9. The measuring cup 9 is movably connected with the limiting groove 21. When the protective cover 16 is installed, the damping rod 19 will push the limiting plate 20 to limit the top of the measuring cup 9. At the same time, the measuring cup 9 is movably connected with the limiting groove 21, which can further improve the limiting stability and sealing of the measuring cup 9.

[0038] refer to Figure 5 and Figure 6 As shown, both the germicidal lamp 22 and the ring light strip 23 are ultraviolet lamps, and the ring light strip 23 is located outside the limiting groove 21. The germicidal lamp 22 and the ring light strip 23 can sterilize the inside and outside of the stored measuring cup 9, preventing bacteria from easily growing in the measuring cup 9 and improving the safety of use.

[0039] Working principle: When using the instrument, the operator places it on a stable surface and observes the bubble level 5 on the top of the base 1. If the bubble deviates from the center, the operator rotates the support adjustment component 6 (threaded sleeve 601) at the bottom of the base 1. The screw 603 and the threaded sleeve 601 drive the instrument to make fine adjustments until the bubble is centered. The ball head 604 and the ball head sleeve 605 in the support adjustment component 6 are movably connected to adapt to different tilt angles of the platform. Combined with the real-time monitoring of the bubble level 5, this ensures that the measuring cup 9 is in a horizontal position, avoiding measurement errors caused by tilting. The liquid (ml) / solid (g) dual graduation lines on both sides of the measuring cup 9 are pre-adapted to different dietary stages after surgery, such as liquid, semi-liquid, and soft food, laying the foundation for accurate measurement in the future. By pressing down on the protective cover 16, the protective cover 16 will push down the support ring 14 and the support spring 13, causing the bottom locking block 17 of the protective cover 16 to separate from the locking groove 12. At the same time, rotate the protective cover 16 so that the bottom locking block 17 of the protective cover 16 is aligned with the embedded groove 11. Then, lift the protective cover 16 upward to quickly disassemble it. Then, take out the measuring cup 9 from the placement groove of the placement seat 8. According to the food state (select liquid for liquid / semi-liquid, select solid for soft food), use the measuring cup 9 to measure the food according to the corresponding scale line (the default basic amount for the first meal is 50ml / corresponding solid amount). Press the "Liquid" or "Solid" function button on control panel 2 to input the diet type into the MCU control module; within 15 minutes after eating, the patient presses the "3 / 6 / 8 / Uncomfortable" feedback button according to their own feeling, and then presses the "Next" button. The display screen 4 immediately displays the next food intake and time (e.g., "Next food intake 60ml, time 14:30"); if "Uncomfortable" is pressed, the display screen 4 prompts "Stop eating and consult medical staff"; after receiving the electrical signal input by the button, the MCU runs the preset algorithm (e.g., "50ml basic amount → 3 / 6 / 8 ... After use, clean the measuring cup 9 and put it back into the placement seat 8. Align the locking block 17 at the bottom of the protective cover 16 with the insertion groove 11 of the groove 7 of the base 1 and insert it. Rotate clockwise to make the locking block 17 slide into the slot 12 along the slide 10. The support spring 13 pushes the support ring 14 upward to close and fix the protective cover 16. At this time, the ultraviolet germicidal lamp 22 and the ring light strip 23 built into the protective cover 16 can be turned on to disinfect the inside and outside of the measuring cup 9.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
