[0035] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.
[0036] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this utility model belongs.
[0037] In order to solve the technical problem that the current hair sample collection cannot be used to extract hair samples of specific length segments, and the hair needs to be re-cut and segmented during subsequent experiments, which is time-consuming and labor-intensive; the applicant has developed a new segmented hair sample collection device. The device can collect hair samples in segments during collection, which is convenient for improving the efficiency of subsequent experiments. At the same time, it helps to conduct experiments on hair samples of specific length segments, effectively avoiding the problem of serial misalignment of hair.
[0038] Specifically, see Figure 1 and Figure 2 , Figure 1 This is a structural diagram of an embodiment of a segmented hair sample collection device of the present application. Figure 2 This is a schematic structural diagram from another perspective of an embodiment of the segmented hair sample collection device of the present application.
[0039] like Figure 1 and Figure 2 As shown, the device includes a pressing plate 100 and a carrier plate 200 . The pressing plate 100 includes a pressing surface 101 , and the carrier plate 200 includes a bearing surface 201 facing the pressing surface 101 .
[0040] One side of the pressing plate 100 is integrally connected to the carrier plate 200 , and the pressing plate 100 can be folded toward the carrier plate 200 so that the pressing surface 101 can be closely disposed with the bearing surface 201 .
[0041] Furthermore, a plurality of hair fixing units 300 are arranged on the bearing surface 201 . The plurality of hair fixing units 300 are sequentially arranged along the first direction and can be used to fix hair.
[0042] Based on the above arrangement, the hair is fixed on the supporting surface 201, and the pressing plate 100 and the supporting plate 200 cooperate to clamp the hair. By synchronously cutting the pressing plate 100 and the supporting plate 200, multiple segmented hair samples can be obtained.
[0043] In a specific implementation, the pressing plate 100 and the carrier plate 200 can be directly used to clamp the patient's hair at the root of the hair. After the hair is cut along the end edges of the pressing plate 100 and the carrier plate 200, the pressing plate 100 and the carrier plate 200 are removed and cut into sections. After the sectioning is completed, the pressing plate 100 of a section can be opened to obtain a hair sample of the corresponding section.
[0044] Since the hair is fully fixed, serial problems are effectively avoided, and segmented hair samples can be directly collected, which helps to improve the efficiency of subsequent experiments.
[0045] In this embodiment, the pressing plate 100 and the carrier plate 200 may be made of cardboard to reduce costs. Of course, in other embodiments, other easily cuttable materials may also be used as the pressing plate 100 and the carrier plate 200.
[0046] In this embodiment, the hair fixing unit 300 is a traceless adhesive fixed to the supporting surface 201. In other embodiments, the hair fixing unit 300 may also adopt other devices capable of gluing and binding hair, such as a band, etc., which can also achieve the effect of this embodiment.
[0047] In addition, in this embodiment, the pressing plate 100 and the carrier plate 200 are designed as an integral body. In other embodiments, the pressing plate 100 and the carrier plate 200 may also be designed as separate bodies, which can also achieve the effect of this embodiment.
[0048] To facilitate cutting of hair samples of a fixed length, in this embodiment, a scale 103 arranged along the first direction is further arranged on the outer surface of the pressing plate 100; at the same time, a scale 103 is also arranged on the outer side of the carrier plate 200 to facilitate observation of hair length.
[0049] In addition, a mark 203 is provided on one end surface of the carrier plate 200. The mark 203 is used to mark the direction of the hair root, so as to facilitate sampling of hair at a specific length from the hair root.
[0050] In other embodiments, the scale 103 may also be arranged on the outer surface of the carrier 200, which can also achieve the effect of this embodiment.
[0051] In addition, in this embodiment, the pressing plate 100 and the carrier plate 200 both have a fixed length. In other embodiments, the pressing plate 100 and the carrier plate 200 may also adopt a retractable structure to make their length adjustable to accommodate patients with different hair lengths.
[0052] In order to ensure that each hair sample can remain fixed before being removed after cutting, the plurality of hair fixing units 300 are evenly arranged at equal intervals in this embodiment.
[0053] To further improve the efficiency of hair segment cutting, see Figure 3 , Figure 3 It is a structural schematic diagram of another embodiment of the segmented hair sample collection device of the present application.
[0054] like Figure 3 As shown, a pair of side panels 400 are arranged between the pressure plate 100 and the carrier plate 200 in the segmented collection device. The side panels 400 can be folded so that the pressure plate 100 can be operated to move toward the carrier plate 200. The pressure plate 100, the carrier plate 200 and the pair of side panels 400 cooperate to form an internal working space.
[0055] Furthermore, a plurality of shear blades 500 are arranged on the pressing surface 101 of the pressing plate 100 and are sequentially arranged along the first direction, and the shear blades 500 are extended along the pressing plate 100 toward the carrier plate 200 .
[0056] It is understandable that when the pressing plate 100 is operated to move toward the carrying plate 200 , the shearing blade 500 can evenly cut the hair sample fixed on the carrying surface 201 into segments, thereby quickly achieving the purpose of collecting hair segments.
[0057] Furthermore, in order to prevent the shearing blade 500 from cutting onto the hair fixing unit 300 , the shearing blade 500 and the hair fixing unit 300 are staggered in this embodiment.
[0058] In addition, in this embodiment, the plurality of shear blades 500 are arranged at equal intervals; in other embodiments, the intervals between adjacent shear blades 500 may also be adjusted based on actual needs.
[0059] In order to facilitate the removal of the cut hair sample and to facilitate the fixing of the hair sample on the carrying surface 201 , the side plate 400 and the pressing plate 100 on one side are detachably connected in this embodiment.
[0060] In this embodiment, the side panel 400 on one side is fixed to the pressing plate 100 via an adhesive layer 401. In other embodiments, the side panel 400 and the pressing plate 100 may be fixed by any other feasible detachable means, such as magnetic fixation, Velcro fixation, etc. In addition, the side panel 400 and the carrier plate 200 on one or both sides may be detachably connected, and the effects of this embodiment can be achieved.
[0061] In this embodiment, the side panel 400, the pressing plate 100 and the carrier plate 200 can be a cardboard structure connected as one body, and a fold can be provided in the middle of the side panel 400 so that the side panel 400 can be folded; in other embodiments, the side panel 400, the pressing plate 100 and the carrier plate 200 can also be other materials, such as plastic, etc., and the side panel 400 can also be other foldable structures, such as an accordion telescopic panel, etc., all of which can achieve the effect of this embodiment.
[0062] In addition, in this embodiment, the hair fixing unit 300 is a traceless adhesive. In other embodiments, it can also adopt any device that can fix the hair, such as a rolling belt, and can achieve the effect of this embodiment.
[0063] In order to improve the shearing effect of the shearing knife 500 on the hair, in this embodiment, a notch 202 matching the blade head of the shearing knife 500 is arranged on the supporting surface 201. During shearing, the blade head of the shearing knife 500 can be embedded in the notch 202 to fully cut the hair sample.
[0064] In addition, in order to facilitate identification of the hair root position, a mark 203 is also arranged on one end surface of the carrier plate 200 in this embodiment.
[0065] To further facilitate the pressing operation of the pressing plate 100, please refer to Figure 5 , Figure 5 It is a structural diagram of another embodiment of the segmented hair sample collection device of the present application.
[0066] like Figure 5 As shown, in this embodiment, the segmented collection device also includes a pair of end plates 600 arranged between the pressing plate 100 and the carrier plate 200, the pair of end plates 600 are arranged at intervals along the first direction, and the end plates 600 are formed with openings 601 for hair to pass through, and the end plates 600 are provided with sliding grooves 602 extending from the pressing plate 100 to the carrier plate 200. The two ends of the pressing plate 100 are installed between the pair of end plates 600 by sliding rods 102 passing through the sliding grooves 602, and a buffer spring 700 is arranged between the pressing plate 100 and the carrier plate 200.
[0067] Based on the above design, during initial operation, hair can be passed through the openings 601 on both sides and secured by the hair securing unit 300 located on the carrier 200. The pressing plate 100 is then pressed along the slide groove 602, and the shear blade 500 on the pressing plate 100 cuts the hair into sections. The pressing plate 100 is then reset by the buffer spring 700, and the sectioned hair sample can be removed from the carrier 200.
[0068] In addition, in order to facilitate identification of the hair root position, a mark 203 is also arranged on the outer surface of the end plate 600 at one end in this embodiment.
