The health examination sanitary napkin S of this embodiment includes a body part S1 for absorbing menstrual blood from a functional point of view and a wing part S2 for maintaining a state of being attached to the user's underwear.

From a structural point of view, the medical examination sanitary napkin S of this embodiment includes an absorbent core 30 for absorbing menstrual blood, a liquid-permeable first cover 10 positioned on one side of the absorbent core 30 , and the absorbent core 30 . A liquid-impermeable second cover 20 positioned on the other side, which is formed on the central side of the second cover 20, and is formed based on menstrual blood absorbed in the absorbent core 30, is formed on the outside of the second cover 20 It is configured to be seen from and is configured to include a through window 40 covered with a transparent film. The color formed based on the menstrual blood absorbed by the absorbent core 30 may be the color of the menstrual blood or the reagent reaction color.

The first cover 10 may be understood as a well-known absorbent cover, and during menstruation, the user's menstrual blood passes through the first cover 10 and is absorbed into the absorbent core 30 . For example, the first cover 10 may be made of a sheet-shaped pure cotton nonwoven fabric, but is not limited thereto.

The second cover 20 may be understood as a well-known waterproof cover, and serves to protect the menstrual blood that has passed through and moved toward the absorbent core 30 from leaking to the outside. For example, the second cover 20 may be formed of a sheet-shaped polyethylene film, but is not limited thereto.

The through window 40 is configured to view the menstrual blood absorbed in the absorbent core 30 from the outside.

The health examination sanitary napkin S of this embodiment includes a plurality of sanitary napkins S on one side of the outer surface of the second cover 20 so as to be visually comparable with the color of the inner side of the second cover 20 seen through the through window 40 . The color is displayed while forming each color area 50 . For example, the plurality of colors 50 may be displayed to form a circular color area along the circumference of the through window 40 , but is not limited thereto.

In the absorbent core 30 , at least a partial area 32 of the area visible to the outside of the second cover 20 through the through window 40 passes through the through window 40 to the second cover 20 . It is configured in a pressed state to have a higher density than the other regions 34 that are not visible to the outside.

In another view, in the absorbent core 30 , at least a portion of an area 32 of the area visible to the outside of the second cover 20 through the through window 40 is provided with the second through window 40 through the through window 40 . The cover 20 is configured in a pressed state to have a thinner thickness than the other regions 34 that are not visible to the outside.

As an example, the absorbent core 30 may be formed of a pad-shaped pulp and/or polymer absorbent paper having a predetermined thickness (eg, 3 to 8 mm), but is not limited thereto. The thickness of the absorbent core 30 may be determined in various thicknesses in consideration of the amount of menstrual blood.

For example, it is preferable that a portion of the region 32 configured in a pressed state be thinly pressed to have a thickness value of about 20 to 50% based on the thickness of the other region 34 , but is not limited thereto. If the press is excessive, the absorbent core 30 may be partially damaged, and if the press is insufficient, it may be unsuitable to obtain the visual effect of this embodiment, so consider the thickness and size of the absorbent core 30 for each product. to determine the press pressurization conditions. The other areas 34 may be unpressed or pressed with a relatively small depression (force or depth) to form a product shape.

If the absorbent core 30 is configured to have the same density or thickness over the entire area, menstrual blood absorbed into the absorbent core 30 passing through the first cover 10 flows toward the second cover 20 in the thickness direction. Before diffusion is sufficiently achieved, it may first be diffused laterally in a thickness position on the side adjacent to the first cover 10 . In this state, the absorption and diffusion of menstrual blood in the thickness direction of the second cover 20 does not proceed sufficiently, so the color of menstrual blood or the reagent reaction color may not be clearly visible through the through window 40 of the second cover 20 . have.

In consideration of this point, in the medical examination sanitary napkin S of the present embodiment, the area 32 of the absorbent core 30 that is seen outwardly of the second cover 20 through the through window 40 is replaced with another area 34, By configuring the pressed state to have a higher density and/or a thinner thickness than the unpressed region), the menstrual blood color or the diagnostic reagent color can be clearly visually seen.

In the region 32 of the absorbent core 30 pressed to have a high density and/or a thin thickness, menstrual blood may be partially absorbed and diffused in a more concentrated state, so that the color of the menstrual blood or the color of the diagnostic reagent is different. It can be visually recognized more clearly than in other areas.

For example, in the partially pressed state of the absorbent core 30 , the absorbent core 30 is stacked in the middle of the first cover 10 and the second cover 20 , and the first cover 10 and the second cover In the process of manufacturing the sanitary napkin S by press-bonding the respective edges 11 and 21 of the 20 to each other, the press mold is configured to partially press the region 32 of the part of the absorbent core 30 deeper can be obtained by In this process, the first cover 10 may also be deformed into a pressed state in the same area as the area 32 of a part of the absorbent core 30 as illustrated in FIG. 5 . However, the press working of the absorbent core 30 is not necessarily limited to the above-described method, and the first cover 10 does not necessarily have a deformed state as shown in FIG. 5 .

For example, the first cover 10 and the second cover 20 have a coupling portion B in the form of surrounding the edge 31 of the absorbent core 30 so that the respective edges 11 and 21 are formed. They are laminated to each other and configured in a press-bonded state.

Preferably, the medical examination sanitary napkin S of this embodiment includes a transparent film cover 60 positioned in the middle between the absorbent core 30 and the second cover 20 . For example, the transparent film cover 60 may be made of a non-toxic antibacterial film (eg, poly-carbonate), but is not necessarily limited thereto.

As an example, the shape of the transparent film cover 60 may be formed as shown in FIG. 3 , but it is not limited to a specific shape as long as the installed position can be stably maintained while covering the through window 40 , and some regions The first cover 10 and the second cover 20 may be positioned to overlap the stacked portions of the edges 11 and 21 and partially press-fixed together.

Using the transparent film cover 60 , the first cover 10 and the second cover 20 each have a coupling portion B in the form of enclosing the rim 31 of the absorbent core 30 . of the edges 11 and 21 are laminated to each other and configured in a press-bonded state, and the through window 40 is covered with a transparent film by the transparent film cover 60 .

As described above, in the medical examination sanitary napkin S of this embodiment, the transparent film cover 60 is positioned between the absorbent core 30 and the second cover 20, and the liquid-permeable first cover 10 and the liquid fire Since the respective edges 11 and 21 are laminated to each other and press-bonded so that the permeable second cover 20 has a shape surrounding the absorbent core 30 and the transparent film cover 60, the first cover ( 10) and in the process of forming the sanitary napkin S by press-bonding each of the edges 11 and 21 of the second cover 20 to each other, a transparent film layer can be naturally obtained, and the penetration of the second cover 20 There is an advantage that a separate process for attaching or adhering the transparent film to the window 40 is not required.

On the other hand, the health diagnosis identification information 80 distinguished by color may be displayed on one side of the plurality of colors displayed on one side of the outer surface of the second cover 20 .

The color region 50 of the plurality of colors is preferably made of a color corresponding to the color of menstrual blood that can be secreted the most among the colors of women's menstrual blood, for example, line pink, bright red, dark purple, orange and It can consist of five colors corresponding to dark brown.

For example, the bright red color is a sign that menstruation starts or indicates a state in which a lot of menstrual blood is not discharged, and the bright red color is expected to be an extremely normal and healthy state (eg, normal hormone levels, smooth blood circulation). However, if it is not the menstrual period, it is advisable to seek additional medical attention from a doctor because inflammation may have occurred or it may be implantation bleeding.

Dark purple is the color of menstrual blood that appears mainly when the amount of menstrual blood is large due to the rapid exfoliation of the endometrium. It may be a sign of , so it is advisable to seek additional medical attention from a doctor.

Orange menstrual blood means that the user is most likely infected with vaginitis, and it is advisable to seek further medical attention.

Dark brown menstrual blood is the secretion of the remaining menstrual blood in the process of almost completing menstruation. In the case of , cancer or other diseases may be suspected, so it is desirable to receive additional examination from a doctor.

That is, the plurality of colors 50 allow the user's health status to be predicted directly or indirectly, and the user can quickly and accurately check his or her health status through his or her menstrual blood color and health diagnosis identification information 80 to be described later. and additional care (e.g. follow-up or visits to a doctor) can be provided.
