Description

Technical Field

[0001] The utility model relates to the technical field of sanitary products, specifically, a pH self-checking sanitary napkin, which is applied to sanitary napkins for daily use of women. Background Art

[0002] A sanitary napkin is a disposable moisture-absorbing item placed in a woman's crotch for absorbing menstrual blood. Under normal circumstances, the normal vaginal flora in a woman's vagina is mainly lactobacilli. However, in some special cases, such as due to diseases or certain bacterial infections, the vaginal flora may be disrupted, which may cause changes in the pH value of the vagina. To more conveniently detect the pH value of women during menstruation, a sanitary napkin that can detect the pH value has emerged on the market.

[0003] For example, a vaginitis detection sanitary napkin disclosed in Chinese patent document CN203598107U includes a PE perforated film, a pH detection chip, a PE airtight bottom film, an adhesive, a release paper, and a PVC aluminized film from top to bottom.

[0004] In the above-mentioned prior art, during actual use, menstrual blood infiltrates the PE perforated film, causing the menstrual blood to enter through the holes and contact the pH detection chip, and the pH detection chip further absorbs the menstrual blood. However, since the menstrual blood on the surface of the sanitary napkin is red or dark red, and even blood clots may accumulate on the surface, it is difficult for users to distinguish or see the color shown by the pH detection chip, so that users are difficult to obtain a pH value reference in practice. Summary of the Utility Model

[0005] In order to overcome the defects existing in the prior art, the utility model provides a pH self-checking sanitary napkin, aiming to solve the problems in the above-mentioned prior art.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a pH self-checking sanitary napkin, including a main body, an absorbent core body is arranged in the main body, one side of the absorbent core body is an absorption surface, the other side is a waterproof surface, a penetration area is arranged on the absorption surface, a pH detection core is arranged on the side of the penetration area close to the waterproof surface, and the pH detection core is attached to the waterproof surface.

[0007] In the above-mentioned pH self-checking sanitary napkin, the absorption surface is an absorption layer, the waterproof surface is a waterproof film, the waterproof film is covered on one side surface of the absorption layer, a plurality of through holes are opened in the penetration area, and the pH detection core is embedded in the absorption layer so that the through holes correspond to the pH detection core.

[0008] In the above-mentioned pH self-checking sanitary napkin, a detection groove is opened on the side of the absorbent core body close to the waterproof film, the detection groove is communicated with the through holes, and the pH detection core is arranged in the detection groove.

[0009] In the above-mentioned pH self-checking sanitary napkin, a diversion area is arranged on one side of the penetration area, and a plurality of arc-shaped grooves are arranged in the diversion area. The plurality of arc-shaped grooves are arranged along the length direction of the absorption layer, and the radii of the plurality of arc-shaped grooves gradually decrease towards the penetration area.

[0010] In the above-mentioned pH self-checking sanitary napkin, a hydrophobic layer is arranged on the surface of the pH detection core. The area of the hydrophobic layer is smaller than the length of the pH detection core, so that one end of the pH detection core forms a liquid absorption end, and the liquid absorption end corresponds to the guide through hole.

[0011] In the above-mentioned pH self-checking sanitary napkin, wings are arranged on both sides of the absorption core body, and a comparison color card film is arranged on at least one side of the wing close to the waterproof surface.

[0012] In the above-mentioned pH self-checking sanitary napkin, flow blocking strips are arranged on both sides of the absorption core body. The flow blocking strips are arranged along the length direction of the absorption core body, and the flow blocking strips are press-fitted and connected with the absorption core body.

[0013] The beneficial effect of the present utility model is that the pH detection core is arranged in the absorption core body, and one side of the pH detection core is attached to the waterproof surface of the bottom surface. That is to say, menstrual blood enters from the penetration area of the absorption core body and then contacts the side of the pH detection core far from the waterproof surface. Due to the filtration of the menstrual blood through the absorption core body, the penetration area and the pH detection core, blood clots stay on the surface of the absorption core body or even within a certain depth of the absorption core body. The remaining liquid contacts the pH detection core when further penetrating downward, so that the pH detection core can show color better, and the pH detection core after showing color can be observed from the side of the waterproof surface, so that users can make better reference.

[0022] The following further describes the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] Combined with Figures 1 to 7 As shown in a pH self-checking sanitary napkin, which includes a main body. An absorption core body 1 is arranged in the main body. One side of the absorption core body 1 is an absorption surface, and the other side is a waterproof surface. A penetration area is arranged on the absorption surface. A pH detection core 6 is arranged on the side of the penetration area close to the waterproof surface, and the pH detection core 6 is attached to the waterproof surface; in this embodiment, by arranging the pH detection core 6 in the absorption core body 1 and making one side of the pH detection core 6 attached to the waterproof surface at the bottom, that is to say, menstrual blood enters from the penetration area of the absorption core body 1 and then contacts the side of the pH detection core 6 away from the waterproof surface. Due to the filtration of menstrual blood through the absorption core body 1, the penetration area and the pH detection core 6, blood clots stay on the surface of the absorption core body 1 or even within a certain depth of the absorption core body 1. The remaining liquid contacts the pH detection core 6 when further penetrating downward, so that the pH detection core 6 can better show color, and the pH detection core 6 after showing color can be observed through the side of the waterproof surface, so that users can better make reference.

[0024] Referring to Figure 3 And Figure 4 As shown in, the absorption surface of this embodiment is the absorption layer 8, and the waterproof surface is the waterproof film 9. The waterproof film 9 is covered on one side surface of the absorption layer 8. A plurality of through holes 4 are opened in the penetration area, and the pH detection core 6 is embedded in the absorption layer 8 so that the through holes 4 correspond to the pH detection core 6; when menstrual blood passes through the through holes 4, it is first absorbed by the absorption layer 8 itself, and at the same time, the remaining part of the menstrual blood contacts one side surface of the pH detection core 6, and the pH detection core 6 absorbs the liquid, so that the pH detection core 6 shows color.

[0025] The waterproof film 9 of this embodiment is a transparent PE film, which enables the waterproof film 9 to have the performance of air permeability and waterproofness. Moreover, a non-woven fabric layer can be covered on the surface of the absorbent core 1, so that when the sanitary pad is in use, the non-woven fabric layer is more comfortable to contact with the skin and can also filter out some blood clots in the menstrual blood first.

[0026] It should be noted that a detection groove is provided on one side of the absorbent core 1 of this embodiment close to the waterproof film 9, and the detection groove communicates with the through hole 4, and the pH detection core 6 is arranged in the detection groove; thus, the pH detection core 6 can be more stably arranged in the absorbent core 1 to prevent displacement and can better absorb and develop color for menstrual blood or liquid. The pH detection core 6 of this embodiment can be formed by pressing multiple layers of non-woven fabrics soaked in methyl red, bromocresol green, and bromothymol blue.

[0027] One side of the penetration area of this embodiment is provided with a diversion area, and multiple arc-shaped grooves 5 are arranged in the diversion area. The multiple arc-shaped grooves 5 are arranged along the length direction of the absorption layer 8, and the radii of the multiple arc-shaped grooves 5 gradually decrease towards the penetration area; through the multiple arc-shaped grooves 5, menstrual blood or liquid can be diverted to the penetration area, and during the diversion process, the arc-shaped grooves 5 can absorb, which is more suitable for users with a large amount of liquid.

[0028] In order to better make the surface of the pH detection core 6 develop color, a hydrophobic layer 11 is provided on the surface of the pH detection core 6. The area of the hydrophobic layer 11 is smaller than the length of the pH detection core 6, so that one end of the pH detection core 6 forms a liquid absorption end 10, and the liquid absorption end 10 corresponds to the through hole 4. Thus, when the liquid absorption end 10 absorbs liquid, the liquid will also enter between the hydrophobic layers 11, so that during the penetration process, the color of the menstrual blood liquid will further fade from the inside to the outside, making the color development on the surface of the pH detection core 6 clearer.

[0029] It should be noted that the hydrophobic layer 11 can be a hydrophobic coating or can be set on the surface of the pH detection core 6 by covering a waterproof film.

[0030] Both sides of the absorbent core 1 of this embodiment are provided with winglets 2, and a color comparison card film 7 is provided on at least one side of the winglets 2 close to the waterproof surface; users can make reference and comparison through the color comparison card film 7, and during the reference and comparison, it is on the back of the absorbent core 1, which is cleaner relative to the absorption surface.

[0031] It should be noted that both sides of the absorbent core 1 of this embodiment are provided with flow-blocking strips 3. The flow-blocking strips 3 are arranged along the length direction of the absorbent core 1, and the flow-blocking strips 3 are press-fitted to the absorbent core 1; the flow-blocking strips 3 can be wound with non-woven fabrics, and the flow-blocking strips 3 are treated with hydrophobic treatment. Through the flow-blocking strips 3, liquid leakage from the side can be reduced, effectively reducing the phenomenon of side leakage.

[0032] The above has described in detail the embodiments of the present utility model in conjunction with the accompanying drawings. However, the present utility model is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
