Description

Technical Field

[0001] The invention relates to the field of sample detection, and in particular to a sampling device. Background Art

[0002] The female vaginal microecological system is one of the components of the human body's microecological system, which is composed of the vaginal microbial flora, endocrine regulation system, vaginal anatomical structure and local immune system. The clinical evaluation system of vaginal microecology evaluates the vaginal microecological environment from the morphological and functional aspects, including the dominant bacteria, diversity and density of vaginal flora, pathogens (such as Trichomonas and fungi), lactobacillus grading, white blood cell count, epithelial cells and some functional indicators (such as pH, sialidase, leukocyte esterase, glucuronidase, acetylglucosaminidase), etc. The vaginal microecological clinical evaluation system can accurately diagnose various gynecological infections, provide important laboratory diagnostic basis for clinicians, and guide effective clinical treatment.

[0003] Morphology is the most important evaluation index in the vaginal microecological evaluation system. The current general clinical operation method is to use a dry cotton swab to scrape the secretions from the upper 1 / 3 of the inner wall of the vagina, smear it evenly on a clean glass slide, perform Gram staining, and then observe it under an upright optical microscope. Clinical practice requires that the thickness of the secretions in the smear is uniform and appropriate, the bacteria are spread evenly, the cells are not stacked, the staining is uniform, and the background is clean.

[0037] That is, the sampling device is mainly composed of a sampling head 10, a rod body 20 and a base 30, wherein a sample storage portion may be provided on one side surface of the sampling head 10, the one side surface of the sampling head 10 may be a smooth plane, the sample storage portion may be a groove with a horizontal bottom surface, and the sample storage portion may be a horizontal area with a defined range, so as to facilitate placing the sample at a predetermined position. The entire sampling head 10 may be transparent, or the bottom wall of the groove 11 may be transparent, so as to facilitate light to pass through the groove 11 for detecting the sample. The sampling head 10 can be arranged at one end of the rod body 20. The sampling head 10 can be integrally formed with the rod body 20. The sampling head 10 can also be detachably arranged at one end of the rod body 20. The base 30 can be provided with a through slot 31. The sampling head 10 and the slot 31 can be square, such as rectangular. The base 30 can be movably sleeved on the rod body 20. When the base 30 is moved, the sampling head 10 can be placed in the slot 31. When the base 30 is moved, the sampling head 10 can also detach the base 30 from the sampling head 10 to detach the base 30 from the rod body 20. The upper wall surface of the slot 31 facing the sample storage part can be a plane.

[0038] During use, the base 30 can be placed on the rod body 20, and the sampling head 10 can be used to take samples so that the samples are placed in the sample storage part. Then, the base 30 can be moved to move the base 30 toward the sampling head 10. Part of the sampling head 10 can be placed in the slot 31 of the base 30 so that the sample on the sample storage part can be scraped flat through the upper wall of the slot 31 to make the sample flat and uniform. The base 30 and the sampling head 10 can be directly tested together under the detection instrument; the base 30 can also be moved until the base 30 is detached from the sampling head 10 to scrape flat the sample on the sample storage part, and the sampling head 10 can be placed under the detection instrument for detection.

[0039] During use, the sampling head 10 and the base 30 can be separated first, and the base 30 can be detached from the sampling head 10 and the rod body 20. After sampling with the sampling head 10, the base 30 can be moved so that the sampling head 10 can be placed in the slot 31, and the base 30 can be continued to be moved so that the base 30 is placed on the rod body 20. When the base 30 moves on the rod body 20 in a direction away from the sampling head 10, the sample on the sampling head 10 is scraped flat, so that the sample is uniform.

[0040] According to the sampling device of the present invention, the sampling device is an integrated sampling and smearing device, and sampling and smearing are simple and convenient. When sampling, the base 30 is placed on the rod body 20, and the sample is taken through the sampling head 10 so that the sample is placed in the sample storage part. After the sampling is completed, the base 30 is moved so that the base 30 moves toward the sampling head, and the upper wall surface of the groove 31 facing the sample storage part will scrape the sample in the sample storage part, so that the thickness of the secretion of the sample taken is uniform, the squeezing of the sample is reduced, the trichomonas is prevented from being crushed, and the accuracy of the test result is improved.

[0041] In some embodiments, a hydrophilic layer may be formed on the surface of the sample storage portion on one side surface of the sampling head 10 to facilitate contact between the sample and the surface, avoid gaps or air between the sample and the surface, avoid the influence of gaps or air on the test results, and improve the accuracy of the test results. A hydrophobic layer may be formed on the area other than the sample storage portion on the surface of one side of the sampling head 10, and the hydrophobic layer can prevent the sample from remaining in the area outside the sample storage portion, making it easier to clean.

[0042] In other embodiments, the sample storage portion may be transparent, and the area on one side surface of the sampling head 10 except the sample storage portion may be opaque, so as to facilitate the detection of the sample in the sample storage portion, avoid the influence of light transmission on the sample storage portion outside the sample storage portion, improve the light contrast, and improve the accuracy of the detection result.

[0043] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the sample storage portion may include at least one groove 11, for example, there may be three grooves 11, one side surface of the sampling head 10 may be a plane, and the bottom wall of the groove 11 is a horizontal plane parallel to the one side surface of the sampling head 10, which is convenient for scraping the sample and reducing the squeezing of the sample to make the thickness of the sample uniform. The sample can be confined in the groove 11 through the groove 11, which is convenient for placing the sample in a predetermined area.

[0044] In other embodiments of the present invention, Figure 1 and Figure 2 As shown, the sample storage portion may include a plurality of grooves 11, and the grooves 11 may extend along the length direction of the rod body 20. The plurality of grooves 11 may be spaced and distributed along the length direction of the sampling head 10, and may be evenly distributed. At least two of the plurality of grooves 11 have different depths, and samples of different thicknesses may be prepared by grooves 11 of different depths. Samples of different thicknesses may be prepared by one sampling head 10 at the same time, and sampling and sample preparation are convenient for detection.

[0045] In some embodiments, the sample storage portion on one side surface of the sampling head 10 may include a plurality of grooves 11, and the depth of at least one groove 11 changes in a step-like or linear gradient, so that the changes of samples of different thicknesses can be detected in one groove 11. Optionally, the depth of the groove 11 may also change uniformly, that is, the bottom wall of the groove 11 may also be inclined.

[0046] A hydrophilic layer may be formed on the inner side wall and the bottom wall of the groove 11, respectively, to facilitate contact between the sample and the inner side wall and the bottom wall of the groove 11. The bottom wall of the groove 11 is a horizontal plane parallel to the surface of one side of the sampling head 10, to facilitate contact between the sample and the bottom wall, and to facilitate uniform thickness of the sample. A hydrophobic layer may be formed on the area other than the groove 11 on the surface of one side of the sampling head 10, and the hydrophobic layer can prevent the sample from remaining in the area other than the groove, and is easy to clean.

[0047] In some embodiments, the bottom wall of the groove 11 may be transparent, and the area on one side surface of the sampling head 10 other than the groove 11 may be opaque, so as to facilitate the detection of the sample in the groove, avoid the influence of the area outside the groove on the groove area due to light transmission, improve the light contrast, and improve the accuracy of the detection result. According to some embodiments, the sampling head 10 may be square, the slot 31 may be square, the rod body 20 may be long strip, the center line of the sampling head 10 along the length direction of the rod body 20 may be colinear with the center line of the rod body 20, and the base 30 is convenient for the cooperation between the sampling head 10 and the base 30 when moving on the rod body 20, so that the sampling head 10 can be accurately placed in the slot 31 of the base 30.

[0048] According to other embodiments, when the sampling head 10 is placed in the slot 31, the upper wall surface of the slot 31 facing the sample storage portion and the side surface of the sampling head 10 can be in the same plane, and when the base 30 moves or detaches from the sampling head 10, it is convenient to scrape the sample into a uniform thickness.

[0049] Optionally, when the sampling head 10 is placed in the slot 31, a slot 32 may be provided at a position on the base 30 corresponding to the sample storage portion, and the slot 32 may be connected to the slot 31. When the sampling head 10 is placed in the slot 31, the sample in the detection groove 11 may be observed through the slot 32, and the base 30 and the sampling head 10 may be tested together under a testing instrument, which is simple and convenient.

[0050] In some embodiments, the notch 32 and the sample storage portion can be rectangular respectively, the length dimension of the notch 32 can be greater than or equal to the length dimension of the sample storage portion, and the width dimension of the notch 32 can be greater than or equal to the width dimension of the sample storage portion, so that the sample in the groove 11 on the sample storage portion can be fully observed.

[0051] Specifically, Figure 1As shown, a handle 21 may be provided at the other end of the rod body 20. The handle 21 may be round or square, or may be sheet-shaped, so that sampling can be easily performed through the handle 21. An anti-slip structure may be provided on the handle 21 to prevent slipping during operation. The anti-slip structure may be an anti-slip material layer, or may be a raised or recessed anti-slip structure.

[0052] In an embodiment of the present invention, the base 30 and the handle 21 are detachably connected by snapping. When sampling, the base 30 and the handle 21 can be snapped together to prevent the base 30 from moving on the rod body 20 and affecting the sampling of the sampling head 10. After the sampling is completed, the base 30 and the handle 21 can be disassembled and separated. Figure 5 As shown, the base 30 can be moved on the rod body 20, so that sampling and sample smearing are integrated, which is simple and convenient.

[0053] In some embodiments of the present invention, the sampling head 10 is detachably disposed at one end of the rod body 20 to facilitate separation of the sampling head 10 from the rod body 20 and to prevent the rod body 20 from occupying a large detection space due to being too long, thereby facilitating detection.

[0054] In other embodiments of the present invention, Figure 4 As shown, when the sampling head 10 is placed in the slot 31, a notch 22 extending along the circumference of the rod body 20 may be provided on the rod body 20 outside the slot 31 and adjacent to the base 30. The notch 22 facilitates shearing or breaking of the rod body 20 and facilitates separation of the rod body 20 from the sampling head 10.

[0055] After sampling is completed, the base 30 is moved so that the sampling head 10 is placed in the slot 31. When the sampling head 10 is placed in the slot 31, the rod 20 can be broken or cut off, and then the base 30 and the sampling head 10 are directly placed under the detection instrument for detection.
