Background

Menstruation is regulated by the interaction of reproductive hormones of the hypothalamus, pituitary gland and ovary, and in the menstrual period and the proliferation period of the menstrual cycle, the level of estradiol and progesterone in blood is very low, so that the negative feedback effect on the adenohypophysis and the hypothalamus is weakened or eliminated, the secretion of gonadotropin-releasing hormone by the hypothalamus is increased, and then follicle stimulating hormone and luteinizing hormone secreted by the adenohypophysis are increased, so that the follicle develops and the estrogen secretion is gradually increased. At this point, estrogen in turn stimulates the endometrium into the proliferative phase. Luteinizing hormone increases the secretion of progestogen, resulting in ovulation. During this period both estrogen and progestin levels are elevated. This produces an enhanced negative feedback inhibition of the hypothalamus and adenohypophysis, which in turn reduces the levels of ovulation stimulating hormone and luteinizing hormone, resulting in a deterioration of the corpus luteum and thus in a reduction of the estrogen and progestin levels. The endometrium is deprived of the support of these two hormones and is exfoliated and bleeded, i.e. menstruation occurs. At this point, the estrogen and progestin decrease begins the next menstrual cycle again.

Detailed Description

The present invention will be described in detail with reference to the following embodiments.

Referring to fig. 1 to 4, the sanitary napkin includes an absorbent layer 1, a liquid locking layer 2, and a film layer 3, which are sequentially disposed, where the absorbent layer 1 includes a flexible cotton substrate 11 and a guiding core 12 embedded in the flexible cotton substrate 11, two ends of the flexible cotton substrate 11 are provided with limiting indentations 13, the guiding core 12 includes a liquid absorbing layer 121 and a guiding layer 122 fixedly connected to the liquid absorbing layer 121, the guiding layer 122 includes a plurality of parallel guiding cavities 1221 abutting against each other, the guiding layer 122 further includes a permeable layer 1222, the permeable layer 1222 may be made of a material with strong liquid absorption, such as compressed cotton, the guiding cavity 1221 includes a liquid inlet 12211 and a liquid outlet 12212, the liquid inlet 12211 abuts against the liquid absorbing layer 121, the guiding cavity 1221 is a hollow structure, the liquid outlet 12212 is wrapped in the permeable layer 1222, and the permeable layer 1222 is partially filled in a gap between the guiding cavities 1221, and the liquid locking layer 1222 is partially filled in the gap, The other part completely covers the liquid outlet 12212, and the cross-sectional area of the liquid inlet 12211 is larger than that of the liquid outlet 12212.

The depth of the limiting indentation 13 is equal to the sum of the thicknesses of the absorption layer 1 and the liquid locking layer 2. This is to limit the boundary of the blood flow, and when the blood flows to the limiting indentation 13, the blood changes the permeation direction and permeates into the vicinity of the limiting indentation 13.

A plurality of sets of liquid guide wires 123 are arranged on the guide core 12. The liquid guide line 123 includes a transverse line and a folding line having a plurality of intersections with the transverse line. The liquid guide line 123 is actually a line pressed out by an indentation process, and the purpose of this is to enable menstrual blood to penetrate in multiple directions when the menstrual blood flows onto the sanitary napkin, rather than penetrating around a point, so that side leakage caused by uneven penetration can be avoided.

The cross section of the guiding cavity 1221 is an inverted trapezoid. The upper portion of the cross-section of the permeable layer 1222 is a plurality of non-adjacent triangles and the lower portion is a rectangle.

The liquid locking layer 2 is made of absorbent cotton 21 and water-absorbent resin 22 wrapped in the absorbent cotton 21. The jelly can be formed after water absorption, so that the backflow of liquid can be avoided. The surface of the absorption cotton 21 is imprinted with a waveguide line 211, and half of the waveguide line 211 is a folding line protruding upwards, and a part of the waveguide line 211 is a folding line protruding downwards. This guides the menstrual blood from the permeable layer 1222 to permeate through the liquid-lock layer 2 in both directions, and to permeate and diffuse toward both ends of the sanitary napkin, without accumulating in the middle of the sanitary napkin.

The back of the film is coated with hot melt adhesive.

Two sides of the film layer 3 are fixedly connected with two bonding wings 4, and an elastic connecting piece 5 is arranged at a right angle formed between the bonding wings 4 and the main body of the film layer 3. The adhesive flap 4 can be folded over to attach the adhesive flap 4 to the outer side of the panty, and the adhesive flap 4 is covered on the back with an adhesive, for example of the glue type, and is covered with a non-stick film so as not to adhere to other locations, and reference can be made to the design of the adhesive flap 4 on both sides of the sanitary napkin according to the prior art. The elastic connecting member 5 is an elastic fabric having a certain liquid absorbing capacity, and may be, for example, a compressed cotton filled with elastic rubber threads, and a soft plastic having a bottom for water isolation, such as a plastic film like a plastic wrap, which has a certain stretching capacity. The elastic connection 5 can help to prevent side leakage when in use.

The guide core 12 is arranged at the center of the cotton soft base layer 11, and the material of the cotton soft base layer 11 can refer to the material of the existing sanitary towel, specifically the material of the sanitary towel surface layer with high clean silk. The liquid absorbent layer 121 is made of a material that easily absorbs liquid, and may be compressed cotton. Lumen 1221 is preferably water-impermeable, such as being formed of plastic, with inlet 12211 being larger than outlet 12212 so that menses from wicking layer 121 can readily enter inlet 12211 and then exit outlet 12212 into permeable layer 1222, and so that permeable layer 1222 will rapidly absorb blood while it is relatively difficult for blood to return to inlet 12211 from outlet 12212; the menstrual blood enters the liquid locking layer 2 again, and is absorbed by the water absorbent resin 22 to form a jelly shape, so that the user can not feel wet and colate; the outermost film layer 3 separates the liquid-impervious layer 2 with menstrual blood from underwear.

The utility model discloses a sanitary towel, the flow direction that can effective control menses, the menses can evenly distributed in sanitary towel, prevent the edge leakage, guide the special construction of core 12 in addition, can effectively prevent that the menses in the sanitary towel from oozing to the sanitary towel surface when the sanitary towel part receives the extrusion, bring more comfortable experience for the user at the in-process that uses.
