Description

Side leakage prevention sanitary towel

Technical Field

The invention belongs to the technical field of A61F13/47 sanitary napkins, and particularly relates to a side leakage prevention sanitary napkin.

Background

The main material of the sanitary towel is cotton-shaped paper pulp and a polymer absorber, and is used for absorbing menstrual blood flowing out from the vagina when women have menstrual flow. The traditional sanitary towel has larger thickness, not only has insufficient comfort, but also has unsatisfactory air permeability, and is easy to cause warm and damp vulvar skin of women so as to influence the skin health. Therefore, the thinning of the sanitary napkin is an important trend, but the thinning affects the ability of the sanitary napkin to absorb menstrual blood, and side leakage is likely to occur.

Chinese patent document CN 110236796 a discloses a side leakage protection sanitary napkin, wherein a strip-shaped groove is disposed at the center of the surface layer of the sanitary napkin body, a plurality of annular grooves are disposed at the periphery of the strip-shaped groove, and a plurality of slotted holes are disposed at the bottom walls of the strip-shaped groove and the annular grooves. The left end on top layer, right-hand member all are equipped with the protecting band, and the protecting band includes absorbed layer and waterproof layer, and a plurality of capillary hoses are buried to the inside of absorbed layer. The invention uses the strip groove, the annular groove and the protective belt to realize triple leakage-proof function by using 'blocking' as the idea. Chinese patent document CN 209285936U discloses a magnetic therapy nanometer sanitary napkin, wherein a plurality of protrusions are arranged on the surface of the sanitary napkin, and the protrusions can realize the distribution, uniform distribution and flow direction limitation of excretory fluid, thereby improving the absorption efficiency of the excretory fluid. The invention reduces the side leakage probability of the discharged liquid by using the 'leading' as the concept.

On the other hand, when viewed from the physiological anatomy, the vagina has a urethral orifice above which the clitoris protrudes, and the outside of the clitoris is covered with labia minora. When the sanitary towel rubs against the urethral orifice and the clitoris during severe activities such as running and the like, urine is easy to overflow, and the life quality of women is affected.

Disclosure of Invention

The invention aims to provide a side leakage prevention sanitary towel taking 'cut-off' as a leakage prevention concept aiming at the defects of the prior art.

In order to achieve the purpose, the technical scheme of the invention is as follows:

the side leakage prevention sanitary towel comprises a sanitary towel body, wherein a tubular container for being inserted into a vagina is arranged on the inner side of the sanitary towel body, and the top of the tubular container is opened.

The invention concept created by the invention is as follows: the menstrual blood is trapped in the tubular container before reaching the sanitary towel through the arrangement of the tubular container, so that the burden of the sanitary towel body is greatly reduced, and the possibility of side leakage is greatly reduced.

As an improvement, the tubular container is fixed with the sanitary towel body, and the bottom of the tubular container is connected to the inner side of the sanitary towel body. The scheme has two functions, namely, the tubular container can play a role in positioning the sanitary towel body after being plugged into the vagina, so that the probability of slippage of the sanitary towel body is reduced, and the side leakage is prevented; secondly, the tubular container is easy to be pulled out from the vagina.

As a further improvement, the sanitary towel body is provided with a concave part for accommodating the tubular container, and the concave part is positioned on the inner side of the sanitary towel body. After the tubular container containing menstrual blood is pulled out of the vagina, the tubular container returns to the depressed portion and the menstrual blood is poured into the depressed portion.

As a still further improvement, the recessed portion is located at a middle position of the sanitary napkin body and is arranged along a length direction of the sanitary napkin body. When the tubular container is pulled out from the concave part to form a vacant position, and the urethral orifice is just positioned at the vacant position after the tubular container is plugged into the vagina, so the sanitary towel can not generate friction on the urethral orifice any more, and the friction discomfort of the urethral orifice caused by violent movement is eliminated.

As a modification, the outer surface of the tubular container is provided with stripes. The stripes are matched with the folds of the inner wall of the vagina, so that the stability of the tubular container in the vagina can be improved.

As an improvement, the tubular container is in a cylindrical shape with the diameter of 2-4 cm.

As a modification, the tubular container is in the shape of a water drop with a large top and a small bottom.

As a modification, the sanitary napkin body comprises an inner side layer, an absorbent core layer and an outer side layer, and the bottom of the tubular container is connected to the absorbent core layer. Menstrual blood leaking from the outer wall of the tubular container is directly absorbed by the absorbent core layer introduced thereinto.

As an improvement, the two sides of the sanitary towel body are provided with protective wings, and double-faced adhesive tapes are arranged on the protective wings. The protective wings and the double-faced adhesive tape are used for fixing the sanitary towel body to the underpants.

As a further improvement, a circle of three-dimensional guard is arranged on the sanitary towel body and arranged along the edge of the sanitary towel body, and the three-dimensional guard protrudes out of the inner side of the sanitary towel body.

In conclusion, the sanitary towel has the advantages that the structure is simple, the manufacture is convenient, the interception function of the tubular container greatly reduces the amount of menstrual blood directly flowing to the sanitary towel body, and the pudendum can keep a dry and comfortable state while the side leakage probability is reduced.
