Description

Technical Field

[0001] This utility model relates to a testing tool for international standards of dysphagia food, and more specifically, it relates to a portable tool for determining the international standards of dysphagia food. Background Technology

[0002] The IDDSI standard provides detailed testing methods (such as the fork drip test, spoon tilt test, and fork puncture test) to define food grades. However, significant challenges exist in current clinical and home practices: 1. Reliance on subjective experience: Current testing methods (such as seeing if food flows out from between the tines of a fork) heavily rely on the operator's personal experience and subjective judgment. Different people may draw different conclusions, lacking objectivity and consistency.

[0003] 2. Non-standard operation: The angle of the spoon tilt and the force of the fork piercing cannot be quantified, resulting in poor repeatability of results.

[0004] 3. High professional threshold: For family members and non-professional nursing staff, the text descriptions and testing methods of IDDSI are difficult to understand and accurately implement, which can easily lead to misjudgment and pose safety risks to patients. Utility Model Content

Detailed Implementation

[0016] The present invention will be further described below with reference to embodiments, but this does not constitute any limitation on the present invention. Any limited modifications made by any person within the scope of the claims of the present invention are still within the scope of the claims of the present invention. See Figures 1-5 This utility model discloses a portable tool for determining the international standard grade of dysphagia food, comprising a main housing 1. The main housing 1 is hollow and cylindrical, with a pen clip 17 fixedly mounted on its side wall. A pointed part 2 is screwed onto the lower part of the main housing 1 for easy disassembly. A pressing part 3 is movably inserted into the upper part of the main housing 1, and an upper limit part 4 and a lower limit part 5 are provided between the main housing 1 and the pressing part 3. The upper and lower limit parts limit the movement of the pressing part 3. A first spring 7 is provided between the pressing part 3 and the lower limit part 5 to enable the pressing part 3 to self-reset. A slider 6 is provided below the lower limit part 5, and in the initial state, the slider 6 is in contact with the lower limit part 5. A constant force spring 8 is installed below the slider 6. It is a coil spring that can be stretched to any length within a set tension range, and the spring force it provides is constant, providing a basis for the probe 10 to apply constant pressure to the food sample. The installation method is as follows: the constant force spring 8 is connected to the pressing part 3 through the bracket 9, and the connection between the bracket 9 and the slider 6 and the lower limit part 5 is a sliding connection. Specifically, the bracket 9 can be installed together with the constant force spring 8 first, then the constant force spring 8 can be installed together with the slider 6, then the bracket 9 can be passed through the slider 6 and the lower limit part 5, then an appropriate amount of sealant or epoxy resin can be poured into the inner cavity of the inverted pressing part 3, and the first spring 7 can be placed in it, then the main housing 1 with the bracket 9 installed can be inverted, and the end of the bracket 9 can be inserted into the sealant or epoxy resin. The bracket 9 can be installed after the sealant or epoxy resin has solidified.

[0017] The distance between the pressing part 3 and the constant force spring 8 is fixed by the connection of the bracket 9. However, since the other end of the constant force spring 8 is connected to the slider 6, when the pressing part 3 continues to press down, assuming that the end of the probe 10 is blocked from descending, the constant force spring 8 will extend as the pressing part 3 continues to press down, thus adapting to the downward movement of the pressing part 3. The state transition is as follows: Figure 2 Switch to Figure 3 . Figure 4This is a schematic diagram showing the state when the probe 10 is not acting on any object and the pressing part 3 is pressed down. During the above process, because the spring force provided by the constant force spring 8 remains constant, the force exerted by the probe 10 on the food sample is always the sum of the spring force provided by the constant force spring 8 and the weight of the slider 6 and the probe 10. This ensures that the force applied to the food sample by the tool remains constant during the testing process. It should be noted that this process does not consider sliding friction between the components. When the pressing part 3 is released, it resets under the action of the first spring 7. At this time, the constant force spring 8 also resets, ultimately causing the slider 6 and the probe 10 to reset.

[0018] In addition, to improve the reliability of the constant force spring 8 installation, a mounting plate is fixedly installed below the slider 6. The outer plate segment of the constant force spring 8 is mounted on the mounting plate, which realizes the installation of one end of the constant force spring 8. Moreover, the mounting plate can strengthen the strength of the outer plate segment of the constant force spring 8 and prevent it from deforming under force during the reset process.

[0019] In this embodiment, the upper limit part 4 includes a slip ring 14 disposed on the outer side of one end of the pressing part 3 and an upper limit ring 15 disposed on the top of the main housing 1 to limit the slip ring 14. The upper limit ring 15 can be screwed to the main housing 1 or ultrasonically welded. The slip ring 14 is slidably connected to the inner cavity of the main housing 1. The upper limit ring 15 limits the slip ring 14, thus achieving upper limit positioning of the pressing part 3 and preventing it from detaching from the top of the main housing 1. The lower limit part 5 includes a lower limit ring fixedly disposed in the inner cavity of the main housing 1, achieving lower limit positioning of the pressing part 3.

[0020] A probe 10 is fixed below the slider 6, extending through and to the outside of the tip 2, and is slidably connected to the tip 2. The probe 10 is used to contact the food sample, and the IDSSI level of the food is determined by the depth of its insertion into the sample. In this embodiment, the probe 10 has two right-angle bends to form a clearance portion for mounting the constant force spring 8.

[0021] To facilitate observation of the depth of the probe 10 inserted into the food sample, a viewing window 16 communicating with its inner cavity is provided on one side of the main housing 1 in this embodiment. A scale plate 11, which is a transparent acrylic plate, is installed in the viewing window 16. A pointer 12 corresponding to the position of the scale plate 11 is fixed on the probe 10. In the initial state, the slider 6 is located below the lower limit ring and the two are in contact. At this time, the pointer 12 points to the zero mark on the scale plate 11. During the test, if the pointer 12 points between the 5th and 6th scale lines, it indicates that the current food sample grade is level 5 - fine paste.

[0022] To measure the angular description of food flowability in the IDDSI standard, a food tilt measuring platform 13 is installed on the outer side of the main housing 1 in this embodiment. Specifically, one end of the food tilt measuring platform 13 is rotatably mounted on the side wall of the main housing 1, and an angle scale is provided in the food tilt measuring platform 13.

[0023] The working principle of this utility model is as follows: For puncture testing of food samples: When using the tool, place it vertically on the food sample surface and ensure the tip of the probe 10 is in contact with the sample surface. Then press the pressing part 3 on the top of the main housing 1 to its maximum stroke. At this time, the state of each component in the tool is as follows: Figure 3 As shown, the probe 10 is inserted into the food sample. Because the cohesiveness of food samples varies, the insertion depth of the probe 10 also varies. Once the pointer 12 stops moving, the IDSI level, reflecting the cohesiveness of the food sample, can be obtained by reading the scale indicated by the pointer 12.

[0024] For the tilt test of food samples: Take a small piece of food sample with a spoon and place it on the food tilt measuring platform 13. Slowly rotate the food tilt measuring platform 13. It should be noted that the food tilt measuring platform is installed with damping in the prior art, meaning that after rotating the food tilt measuring platform 13, releasing it will prevent it from rotating on its own due to the damping force. During this process, the operator closely observes the food sample. When the food sample begins to slip or deform, stop rotating. At this time, read the angle scale on the food tilt measuring platform 13. If the food sample slips when tilted at an angle of less than 45 degrees, it may correspond to IDDSI level 4 (extremely viscous); if it hardly flows during tilting, it may correspond to a higher level. The level can be determined by comparing it with the angle description of food flowability in the IDDSI standard.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
