Description

Technical Field

[0001] The utility model relates to the technical field of skin detection, and particularly to a sampling device for identifying rosacea. Background Art

[0002] Rosacea, also known as acne rosacea or rhinophyma, is a common chronic and recurrent inflammatory skin disease that mainly affects the facial blood vessels and the perifollicular sebaceous gland units.

[0003] Rosacea is related to the infection of Demodex (also known as Demodex folliculorum), and the quantitative detection of Demodex has diagnostic value and significance. The Demodex examination method for rosacea is of great significance for the diagnosis of rosacea and the follow-up during the treatment process.

[0004] The Demodex examination method for rosacea mainly uses microscopic examination. After obtaining samples by scraping, squeezing or transparent adhesive tape method, the samples are placed under a microscope to observe whether there is Demodex infection.

[0005] For example, after cutting the transparent adhesive tape into an appropriate size, it is pasted on the skin or both sides of the nose of the patient for several hours or overnight, and then the adhesive tape is removed and pasted on a glass slide for microscopic observation. During the whole operation process, the adhesive surface of the transparent adhesive tape is easily touched by the hand, resulting in sample contamination. Summary of the Utility Model

[0006] In view of the above problems, the present utility model is proposed to provide a sampling device for identifying rosacea that overcomes or at least partially solves the above problems.

[0007] The sampling device for identifying rosacea includes a sampling tape and a release film covering the sampling tape; the sampling tape is in a strip shape and is composed of a number of sampling units arranged in sequence; each sampling unit includes a flexible rectangular carrier sheet and a flexible circular sampling sheet; the adjacent carrier sheets are connected in a discontinuous manner; the diameter of the sampling sheet is smaller than the width of the carrier sheet, and the sampling sheets are stacked and fixed at the central area of the main plane of the carrier sheet; a glue layer is provided on the main plane of the sampling sheet facing away from the carrier sheet; the release film is in a strip shape and is composed of sub-release films with the same number as the sampling units arranged in sequence, the main plane size of the sub-release film is the same as the main plane size of the carrier sheet, and the adjacent sub-release films are connected in a discontinuous manner; each sub-release film covers the glue layer and is symmetrically arranged with the corresponding carrier sheet; a colored identification circle is provided on the outer peripheral edge of the main plane of the sampling sheet.

[0008] In one embodiment, the sampling device for identifying rosacea further includes a reel, and the sampling tape and the release film are wound together on the reel.

[0009] In one embodiment, the carrier sheet and the sampling sheet are integrally formed.

[0010] During the sampling operation using the sampling device of the present utility model for identifying rosacea, no additional cutting is required, and the operation is more convenient. The direct objects of hand operation are mainly the carrier sheet without the adhesive layer and the sub-release film, which can avoid the adhesive layer being contacted by the hand, thereby reducing the probability of sample contamination.

[0020] Next, a sampling device for differentiating rosacea according to an embodiment of the present utility model will be described with reference to the drawings.

[0021] See Figure 1 , a sampling device for differentiating rosacea according to an embodiment of the present utility model includes a sampling tape and a release film covering the sampling tape. The release film can protect the sampling tape before sampling to avoid being contaminated by hand contact.

[0022] Now see Figure 1 and Figure 2 , the sampling tape is strip-shaped and is composed of a plurality of sampling units arranged in sequence. Each sampling unit includes a flexible carrier sheet in a rectangular shape and a flexible sampling sheet in a circular shape. The adjacent carrier sheets are connected in a point-breaking manner, that is, a plurality of through holes arranged along the length direction are formed at the connection of the adjacent carrier sheets to facilitate tearing and separating each carrier sheet.

[0023] The diameter of the sampling piece is smaller than the width of the bearing piece, and the sampling pieces are stacked and fixed at the central area of the main plane of the bearing piece. Specifically, the area of the main plane of the sampling piece can be determined according to the specific part detected by the Demodex folliculorum examination method for rosacea. For example, the area of the main plane of the sampling piece can be 5 cm 2 , 2 cm 2 , 1 cm 2 , or other suitable area sizes. A glue layer is provided on the main plane of the sampling piece facing away from the bearing piece, and the glue layer is used to adhere to the sample during the sampling process.

[0024] Now refer to Figure 1 and Figure 3 , the release film is strip-shaped and is composed of sub-release films arranged in sequence with the same number as the sampling units. The main plane size of the sub-release film is the same as that of the bearing piece, and the adjacent sub-release films are connected in a discontinuous manner. Each of the sub-release films covers the glue layer and is symmetrically arranged with the corresponding bearing piece. One or more relatively sampling units and sub-release films can be torn off and separated from the sampling device together, thus omitting the cutting operation.

[0025] When using the sampling device for identifying rosacea to conduct the Demodex folliculorum examination for rosacea, the following steps can be adopted: Tear off and separate a certain number of sampling units and sub-release films from the sampling device, then tear off the sub-release film, hold the bearing piece and stick the sampling unit on the cleaned skin or both sides of the nose wing, then gently press the bearing piece to make the glue layer completely fit the sampled position. After several hours, gently pull the bearing piece by hand to remove the sampling unit, and then stick the glue layer of the sampling unit facing and on the glass slide and observe under the microscope. During the whole operation process, the probability of the glue layer contacting the hand is greatly reduced, thereby reducing the probability of the sample being contaminated. The main plane area of the bearing piece or the area of the glue layer is a definite value, which is convenient for counting the number of Demodex folliculorum.

[0026] In this embodiment, a color-containing identification circle is provided on the outer peripheral edge of the main plane of the sampling piece, which is convenient for showing the boundary of the main plane of the bearing piece or the glue layer when observing under the microscope.

[0027] The bearing piece and the sampling piece can be integrally formed. Specifically, they can be integrally injection-molded with a synthetic material having a high light transmittance. For example, they can be integrally injection-molded with an optically transparent silicone material.

[0028] In one embodiment, the sampling device for identifying rosacea further includes a reel (not shown in the figure), and the sampling tape and the release film are wound together on the reel. Before sampling, unwind the required number of sampling units and sub-release films, and then tear them off and separate them together.

[0029] During the sampling operation using the sampling device of this embodiment for identifying rosacea, no additional cutting is required, and the operation is more convenient. The direct objects of hand operation are mainly the carrier sheet without the adhesive layer and the sub-release film, which can avoid the adhesive layer being contacted by the hand, thereby reducing the probability of sample contamination.
