Abstract
Description
Technical Field
[0001] This utility model relates to the field of skin testing technology, specifically to a water-proof structure for assisting in the positioning of a skin ultrasound diagnostic instrument. Background Technology
[0002] The skin ultrasound diagnostic instrument is used to test the thickness and density of the skin. Referring to the group standard "T / CAB 0152—2022 Test Methods for Seven Efficacy of Cosmetics: Anti-wrinkle, Firming, Moisturizing, Oil Control, Repairing, Nourishing and Soothing", it can be used as a method to evaluate the nourishing and firming effects. The instrument has two measurement methods: one is using a coupling agent, and the other is water injection measurement.
[0003] Since the coupling agent's main components are carbomer and glycerin, which have a certain moisturizing effect on the skin, they can affect the measurement of the skin's physiological parameters. Furthermore, the use of the coupling agent often introduces air bubbles, which can also affect the test results. Therefore, the second water-injection test method is commonly used. This method results in a large amount of water (approximately 5ml) flowing out the moment the device is lifted after measurement, causing the subject's skin and clothing to become wet, often causing discomfort. The overflowing water also affects subsequent skin tests, reducing the researcher's testing efficiency. Additionally, a large amount of disposable paper towels are often needed to wipe away the overflowing water during the test. Secondly, the skin ultrasound diagnostic instrument itself does not have a localization function; in each test, the evaluator's experience is required for fuzzy localization. Utility Model Content

[0028] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.
[0029] Example 1:
[0030] This invention provides a water-proof structure for assisting in the positioning of a skin ultrasound diagnostic instrument. It includes a water-proof component 1 with a positioning hole 11 located in the center. The positioning hole 11 allows the probe of the skin ultrasound diagnostic instrument to pass through and positions the probe. The shape of the positioning hole 11 matches the shape of the probe, allowing the probe to pass through without radial movement. In use, the water-proof component 1 adheres to the skin due to its hydrophilicity, with the positioning hole 11 facing the test area. After passing through the positioning hole 11, the skin ultrasound diagnostic instrument probe can directly contact the test area of the skin.
[0031] Specifically, the overflow prevention component 1 is made of sponge material, with a sponge sheet structure and uniform thickness in all parts. In practical applications, not all common absorbent materials are suitable for making the overflow prevention component 1. For example, cotton, linen, polyester, non-woven fabric, and polyester fiber are not suitable. The overflow prevention component 1 in this invention is best made of a material with a large pore size and strong instantaneous water absorption. Konjac sponge is preferred for the overflow prevention component 1. Konjac sponge has the advantages of being soft and skin-friendly, and capable of instant water absorption. After use, the konjac sponge can be squeezed out of the water and then soaked in alcohol for disinfection, allowing it to be reused for the next round of testing, making it environmentally friendly and convenient. This invention solves the problem of overflow and leakage, accurately locates the test site, improves the comfort of the test subject, increases the testing efficiency of the researcher, reduces paper waste caused by wiping water with paper, and is a reusable product, saving resources and avoiding waste, making it very environmentally friendly.
[0032] In practical applications, the minimum maximum outer diameter of the anti-overflow component 1 is ≥1.5 cm, preferably greater than 3 cm. For example, the minimum maximum outer diameter of the anti-overflow component 1 is 4 cm, making it small in size and lightweight, and convenient to carry for outdoor testing. The anti-overflow component 1 in this invention can quickly and effectively absorb water spilled when the skin ultrasound diagnostic instrument is removed, reducing the inconvenience caused to the subject by the instrument itself and improving testing efficiency. Due to the absorbency of the konjac sponge, the use of a large amount of paper towels is avoided, which not only reduces the impact of paper towel friction on the skin but also has the advantage of being environmentally friendly.
[0033] To improve the positioning effect, the thickness of the anti-overflow component 1 is 1 cm to 2 cm, preferably 1.2 cm to 1.8 cm, for example 1.5 cm.
[0034] This invention is based on the principle of the cosmic expansion model and combines the characteristics of two-dimensional spatial curvature changes to achieve precise positioning. The cosmic expansion model describes the changes in spatial scale factors, where different regions expand at different rates, resulting in non-uniformity of the geometric structure during temporal evolution. Inspired by this, the shape design of the anti-overflow component 1 in this invention incorporates a similar non-uniform form, enabling it to provide precise positioning and stable support in different skin areas. A teardrop shape (or a similar streamlined shape) is recommended, as the curvature changes of its two-dimensional contour effectively guide the placement of the probe. According to the mathematical characteristics of the cosmic expansion model, the rate of spatial expansion is non-uniform. Correspondingly, in this invention, the curvature at different locations can optimize the contact and positioning of the probe. The wide end region (low curvature) of the teardrop shape provides more stable support, ensuring the device remains stable on relatively flat areas such as the cheeks and neck; the pointed tip region (high curvature) of the teardrop shape provides precise guidance, allowing the probe to be kept in the center of a smaller test area for measurement, such as the corner of the eye and local wrinkle areas. However, in different test projects, shapes such as elliptical, petal-shaped, circular, and square shapes can also be used according to different needs. Each shape has its own advantages and disadvantages. For example, a circle is uniform and symmetrical, suitable for measurement needs that do not require directional adjustment, and provides stability but has slightly weaker precise positioning ability; square edges and corners can be used for testing special parts, but may cause uneven force on the contact surface; petal-shaped multiple boundaries can adapt to irregular skin areas and are helpful for testing complex areas.
[0035] The basic embodiments of this utility model have been described above. The following describes the application in more detail with reference to preferred embodiments and / or variations of the basic embodiments.
[0036] Example 2:
[0037] In this embodiment, a teardrop shape is used as an example. A hole suitable for the probe of a skin ultrasound diagnostic instrument is drilled in the anti-overflow component 1 as a positioning hole 11. The probe is of model Ultrascan UC22 and has a rectangular hole of 15mm*25mm. The anti-overflow component 1 is as follows. Figure 1 , Figure 2 As shown.
[0038] Figure 3 , Figure 4 The image shows a front and side view of the Ultrascan UC22 skin ultrasound diagnostic instrument (example); Figure 5 , Figure 6 The image shows a front and side view of the Ultrascan UC22 skin ultrasound diagnostic instrument after the anti-overflow component 1 is inserted, using an anti-overflow structure that assists in positioning the skin ultrasound diagnostic instrument.
[0039] Drawing inspiration from the force distribution changes during the expansion of the universe, this invention employs a wrap-around design to ensure that the measuring probe can be stably inserted into the positioning hole 11 in the center of the overflow prevention component 1. The shape and contour of the probe insertion into the positioning hole 11 match, ensuring uniform force distribution during fixation and preventing displacement due to asymmetrical force.
[0040] Referring to the Hubble parameters, we have listed the shape factor (H) in this invention. shape )formula:
[0041]
[0042] The shape factor describes how shape affects liquid diffusion and probe stability.
[0043] The Hubble parameter in the cosmic expansion model is:
[0044]
[0045] in:
[0046] H (Hubble parameter) represents the rate of expansion of the universe, equivalent to how shape affects the distribution of liquids or energy. a (scale factor) corresponds to the shape and size of the device, i.e., the area A.
[0047] The rate of change of the scale factor corresponds to how the boundary of the shape affects the flow, i.e., the perimeter P.
[0048] A key concept in the cosmic expansion model is that space itself is expanding, rather than objects moving within it. The effect of different shapes can be likened to the expansion effect of boundaries; for example, a teardrop-shaped boundary resembles a localized expansion region in the early universe, capable of guiding energy (i.e., guiding the flow of liquid in a device).
[0049] The testing principle of this utility model is as follows:
[0050] Place the anti-overflow component 1 in the area to be tested. The area aligned with the positioning hole 11 is determined according to the test area. Slowly insert the skin ultrasound diagnostic probe into the positioning hole 11 and gently squeeze the sponge downwards. Slowly inject water. Stop injecting water and taking pictures when the image is clearly and completely presented. After the image is taken, slowly lift the probe. As it bounces up, the sponge also slowly bounces back. At this time, the water will be almost completely absorbed by the sponge. After removing the probe, take out the sponge, squeeze out the water, and soak it in alcohol for use in the next round of testing.
[0051] Verification of the structure in this invention has shown that it significantly reduces water overflow by 96.67%, reduces the amount of paper towels used by 83.33%, and significantly improves the accuracy of the number of people located, as well as the comfort of the test subjects. This indicates that the structure can effectively solve the water overflow problem, reduce paper waste, provide high accuracy in instrument testing after positioning, greatly improve the comfort of the test subjects, and enhance the testing efficiency of researchers.
