Abstract
Description
Technical Field
[0001] This application relates to the field of chemical detection, and in particular to a hair treatment device. Background Technology
[0002] Currently, the variety of drugs is complex and their detection is challenging, leading to a growing demand for rapid, accurate, broad-spectrum, and highly sensitive drug detection methods. Conventional detection methods primarily involve testing for drugs in bodily fluids such as urine and blood. However, drugs in bodily fluids are metabolized quickly and easily adulterated. Hair samples, on the other hand, are increasingly becoming a new indicator of drug addiction due to their stability, ease of acquisition, long detection window, resistance to contamination, and the stable drug components they contain. Currently, the main conventional methods for detecting drugs in hair are:
[0003] 1. On-site rapid screening mainly uses colloidal gold, quantum dot fluorescence, Raman spectroscopy, etc. Its main drawback is:
[0004] It suffers from drawbacks such as a high probability of false positives / negatives, a narrow detection range (one or several types), and low sensitivity. In actual testing, it requires repeated manual operation and judgment, which reduces the reliability of the results.
[0005] 2. Laboratory testing mainly utilizes acid hydrolysis, alkaline hydrolysis, solvent ultrasonication, and dry grinding; the main drawback of this approach is:
[0006] The current method suffers from drawbacks such as long processing time, high testing costs, and complex operation. For example, the Ministry of Justice's standard SF / Z JD0107025-2018, "Liquid Chromatography-Tandem Mass Spectrometry Method for the Detection of 15 Drugs and Their Metabolites in Hair," specifies a hair sample processing procedure involving washing, drying, cutting, weighing, freeze-grinding, sonicating in an ice bath, centrifugation, then removing the supernatant, drying, reconstituted, and entering the mass spectrometer for detection. This method is cumbersome, time-consuming, labor-intensive, requires multiple pieces of equipment, and can easily produce unpleasant odors for operators. Furthermore, it requires professional personnel to operate the mass spectrometer and demands high precision in the pretreatment results. Therefore, there is an urgent need for a simpler, fewer-step pretreatment method to replace it. Summary of the Invention
[0007] To address the aforementioned problems, this application provides a hair treatment device.

The hair treatment device provided in this application requires only two test tubes to complete the extraction of hair components, making it simple and efficient. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the grinding apparatus of this application will be further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.
[0042] The serial numbers assigned to components in this document, such as "first" and "second," are used solely to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages). It should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used solely for the convenience of describing this application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0043] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0044] Please see Figure 1 This application provides a hair treatment device 10, which includes a first test tube 110 ( Figure 1 a) and second test tube 120 ( Figure 1 (b) The diameter of the second test tube 120 is smaller than the diameter of the first test tube 110. The length of the second test tube 120 is smaller than the length of the first test tube 110. Therefore, the second test tube 120 can be placed inside the first test tube 110. Please refer to [link / reference]. Figure 1 c. The bottom of the second test tube 120 has a first perforated structure 121. Liquid in the second test tube 120 can leak out through the first perforated structure 121. A filter membrane 122 is provided at one end of the second test tube 120 near the first perforated structure 121. The filter membrane 122 can be used to filter the polishing liquid generated after polishing the hair, and the cleaning liquid used to clean the hair in the second test tube 120 can also leak out through the filter membrane 122 and the first perforated structure 121 and enter the first test tube 110.
[0045] In some embodiments, the bottom of the first test tube 110 is conical; therefore, the first test tube 110 can be easily placed in equipment such as a centrifuge. The bottom surface of the second test tube 120 is flat.
[0046] Please see Figure 2 In some embodiments, the hair treatment device 10 further includes a clamping structure 130. The clamping structure 130 fixes the filter membrane 122 to the bottom of the second test tube 120 to prevent the filter membrane 122 from shaking during washing or centrifugation.
[0047] In some embodiments, see Figure 2 b. The clamping structure 130 is a plate-like structure, and the filter membrane 122 is fixed between the perforated structure and the bottom of the second test tube 120; the clamping structure 130 is provided with a second perforated structure 132. That is, the filter membrane 122 is clamped between the perforated structure and the bottom of the second test tube 120. The liquid in the second test tube 120 can flow out of the second test tube 120 through the second perforated structure 132 and the filter membrane 122.
[0048] In some embodiments, a receiving space 140 is provided between the clamping structure 130 and the bottom of the second test tube 120, and the filter membrane 122 is disposed in the receiving space 140. The size of the receiving space 140 may be adapted to the size of the filter membrane 122, or smaller than the filter membrane 122, so as to achieve the purpose of clamping the filter membrane 122.
[0049] In some embodiments, the second perforated structure 132 is a plurality of circular holes arranged in an array. The diameter of the circular holes may be smaller than the diameter of a hair, and / or smaller than the diameter of the abrasive beads 124.
[0050] In some embodiments, a plurality of the grinding beads 124 are disposed in the second test tube 120.
[0051] In some embodiments, the size of the abrasive bead 124 is larger than the size of the circular hole structure. Therefore, the abrasive bead 124 is less likely to leak out of the circular hole structure.
[0052] The second test tube 120 has a flange 150 at its opening, and the diameter of the flange 150 is larger than the diameter of the first test tube 110. Therefore, the second test tube 120 can be hung on the opening of the first test tube 110 through the flange 150 without falling into the first test tube 110.
[0053] For the method of using the hair washing device provided in this application, please refer to the following embodiments:
[0054] Please see Figure 3 First, weigh the second test tube 120.
[0055] Please see Figure 4-5The second test tube 120 is placed inside the first test tube 110 and weighed together. The hair to be tested can be placed in the first test tube 110. Then, the cleaning solution is placed in the second test tube 120. The hair can be cleaned by stirring, shaking, etc. Then, the cleaning solution is centrifuged and filtered through the first hollow structure 121, the filter membrane 122 and the second hollow structure 132 into the first test tube 110.
[0056] Please see Figure 6 The second test tube 120 and the hair are removed from the first test tube 110, dried, and weighed.
[0057] Please see Figure 7 Place the second test tube 120 into the first test tube 110, add the extract and grinding beads 124 to the second test tube 120, and stir and grind.
[0058] Please see Figure 8 The extract is centrifuged or otherwise forced through the first perforated structure 121, the second perforated structure 132, and the filter membrane 122 from the second test tube 120 into the first test tube 110. By analyzing the components of the extract, the composition of the hair can be determined. Based on the quality of the hair and the weight and content of the extract, the presence of drugs can be analyzed.
[0059] The cleaning solution is a water-acetone cleaning solution. Since hair grows on the body surface, drugs in the hair can enter not only through metabolism from the blood, but also through sweat, sebaceous glands, or external environmental pollution. Cleaning has two main purposes: first, to remove hair care products, sweat, sebum, or surface substances that may interfere with analysis or reduce extraction recovery; second, to remove potential external drug contamination from the environment. Currently available cleaning methods include methanol-water and acetone-water. Using the same batch of blank hair, blank hair matrix extracts were prepared by cleaning and grinding with water-methanol and water-acetone respectively. Methamphetamine standard substances were added, and the ratio of the matrix spike concentration to the corresponding standard substance solution concentration was calculated. The hair matrix effects under the two different cleaning conditions were 80.1% and 80.7%, respectively. Since methanol can extract more components from the hair interior, the water-acetone cleaning method was used.
[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
