Description

TECHNICAL FIELD

The invention relates to a contraceptive device, in particular to a female intravaginal barrier type contraceptive device. Background technique

Intravaginal barrier contraceptive devices currently include uterine caps, vaginal diaphragms and condoms. Because cervical caps and vaginal diaphragms are difficult to place and fail easily, they are rarely used today. The vaginal condom developed abroad in 1990 is similar to a male condom. It is a blind tube made of soft film. It is used by women. It is the same as a male condom. It completely isolates the sex organs without any direct contact. Sexual pleasure and sexual psychology are not promoted. The searched name is "Contraceptive Pouch", US Patent No. 6.170.484B1. Disclosed is a contraceptive device made of flexible material, the structure of which is: the upper part is a fully closed capsule base which can be covered on the cervix. The bottom of the capsule expands to form a capsule, and the shape of the capsule is consistent with the shape of the vaginal expansion area. The lower end of the capsule body extends longitudinally into the capsule to form a capsule tube, and the bottom end of the capsule tube is opened in the capsule. The capsule tube is a longitudinal channel for receiving the penis. The outer wall of the capsule can be provided with a ring-shaped stack, or scale-like folds. The user is able to safely contracept, enhances sexiness and is easy to use. It is understood that the contraceptive pouch uses natural rubber latex as the raw material and is processed by a mold. Due to the particularity of its structure, the mold itself is not easy to process and is easily damaged during production. The cost of the product is high, and if it is repeatedly used, it is easy to breed bacteria, so it is difficult to promote the use. Summary of the Invention

The object of the present invention is to overcome the shortcomings of the prior art and provide a female barrier type.

A contraceptive device, which can effectively prevent contraception, is convenient to use, and has a low manufacturing cost, and at the same time has the functions of preventing disease, treating, helping, and improving the quality of sexual life.

The object of the present invention is achieved by the following technical solution, providing a female barrier contraceptive device, which is a spherical entity made of an elastic material, the shape of the entity is consistent with the shape cavity of the expansion region of the upper vagina, and The upper end and the lower end each have a concave surface, and a plurality of convex rings are arranged on the solid outer wall.

The concave surface on the upper end of the solid body can cover the cervix, and the convex surface on the concave surface and around the cervix can be stimulated. The concave surface of the lower end of the solid body is designed as a lip shape or a glans shape of a penis, and the concave surface is provided with a protrusion that can stimulate the penis.

The entity itself is composed of an upper part, a lower part, and an interlayer disposed therebetween. The interlayer is a curved surface, Flat or flat with outer ring structure.

The interlayer of the entity is disposed in the middle, or near the upper end, or near the lower end.

There is a cup-shaped isolation skeleton inside the entity.

The outer wall of the entity is provided with a small blind hole for storing a medicinal solution, which contains a medicinal solution for treating gynecological diseases, a lubricant, a booster or a spermicide.

The entity is made of non-toxic polymer elastic material or sponge.

The outer ring of the interlayer has a ring structure or a cup-shaped isolation skeleton, and is made of a non-toxic polymer elastic material having a hardness greater than that of a solid material.

Compared with the prior art, the female barrier type contraceptive device of the present invention has the following advantages:

1. Increase sexiness and safe contraception; the elastic entity is located in the spherical cavity in the upper part of the vagina, which can meet the filling needs unique to female sexual excitement. The concave surface of the upper part of the solid is close to the cervix, and the sperm is blocked by the elastic entity, which can ensure that the sperm cannot enter the uterus. The sexually sensitive area in the lower part of the vagina is completely exposed, and there is sufficient and direct natural contact with the penis, which is very sexy.

2. Disease prevention and boost: The entity itself and the raised ring designed on the outer wall of the entity can prevent harmful bacteria from entering the uterus. According to the principle of bionics, bulges for stimulating the cervix and penis are designed on the upper and lower ends of the body to enhance the required stimuli and enhance the sexual pleasure of both men and women. Lip-shaped or penis glans-shaped concave surfaces are designed on the body to enhance both men and women Sexual interest, increase the interest. This is more conducive to the active implementation of family planning.

3. Treatment and boost: The spacer layer in the entity can isolate two functional drugs. The upper part can be impregnated with anti-inflammatory, antipruritic, sterilizing and analgesic drugs according to women's needs to treat gynecological diseases such as vaginitis, cervicitis, cervical erosion; or women impregnated with lubricants to dry the vagina, eliminate pain and enhance pleasure ; Or impregnated with booster to eliminate female apathy and act as a pessary for women with sagging uterus.

4. The solid partition is set in the middle, close to the upper end, close to the lower end, or a cup-shaped isolation skeleton made of an elastic material that is harder than the solid material, which can enhance the tension and meet the special filling of some women with a strong sense of emptiness Demand, and has a "gripping" effect on the inserted penis, which can enhance men's sexy.

5- The simulation enhances the natural pleasure of both men and women, and provides convenience for women with sexual requirements during menstruation. It is safe to use, non-toxic and harmless, easy to operate and easy to use.

6. Low manufacturing cost. The entity is made of non-toxic polymer elastic material. The middle spacer and cup-shaped isolation frame are also made of non-toxic polymer elastic material. The processing is easy, the manufacturing cost is greatly reduced, and it can be used once, which is convenient for popularization. . When in use, the elasticity of the material is used, and it is rolled into a thin rod shape. After pushing into the upper part of the vagina, it can be deployed and positioned by itself.
