Description

Inserter for female condom and method of use thereof

Technical field:

The invention belongs to the field of contraceptive products and auxiliary tools thereof, and in particular relates to a female condom inserter and a using method thereof.

Background technique:

It is well known that condoms are effective in preventing sexually transmitted diseases. Today, 340 million people are infected with sexually transmitted diseases every year, such as genital herpes, viral hepatitis, bacterial vaginosis, pelvic inflammatory disease, syphilis and other sexually transmitted diseases, and some sexually transmitted diseases may be fatal, such as AIDS. It is one of the most serious health problems in the world. Since the first report in 1981, an estimated 35 million people in the world are living with AIDS and tens of millions of people have died from AIDS. Among those infected with HIV, 52% were women. Research shows that women are more likely to be infected with HIV than men. Other STDs, while not fatal, can cause serious health problems and discomfort in people. Therefore, all necessary precautions should be taken to prevent sexually transmitted diseases. And wearing a condom is one of the most effective and low-cost methods. In addition, condoms are effective in preventing unplanned pregnancies.

Whether it's preventing HIV, avoiding other STDs, or reducing your chances of getting pregnant, the condom is an effective tool because it's low-cost and can be used without any special training.

Studies have shown that the emergence of female condoms has increased the safety of sex and can effectively reduce the probability of infection and transmission of diseases (including AIDS). Proper use of the female condom can reduce a woman's risk of HIV infection by 94% to 97%.

The female condom is a film pocket closed at one end, an elastic inner ring is placed at the closed end, and an elastic outer ring is bonded at the open end. When in use, the inner ring will be close to the end of the vagina, and the outer ring is larger and thinner, and will always be placed outside the vaginal opening when in use. Compared with male condoms, female condoms have the following advantages:

1. There is a flexible ring at both ends of the female condom. The bottom of the condom is completely closed. When in use, it will be close to the end of the vagina. The outer ring is larger and thinner. When in use, it will always be placed outside the vaginal opening to block The direct contact between the root of the male penis and the female vulva during intercourse prevents the spread of germs more effectively than the male condom.

2. Due to the unique design and special materials of the female condom, it can prevent the transmission of various venereal viruses and HIV to the greatest extent. The female condom is inserted into the vagina by hand, it can be inserted hours before sex, or it can be used immediately. Different from the male condom, it does not require the male erect penis as an aid for the insertion and removal of the condom, so that the sexual process will not be stopped or interrupted, and it also alleviates the male resistance to wearing a condom in the past. If the female condom is well concealed, the man may complete the entire sex act without realizing that his female partner is wearing a condom.

3. Female condoms are less likely to cause urethritis or cystitis in women than male condoms. The male condom induces friction between the condom and the walls of the woman's vagina and the opening of the woman's urethra, thus sometimes causing so-called urethrocystitis. The inner diameter of the female condom body is large, and if the outer ring does not move, the main friction is between the female condom and the skin of the male penis. Therefore, the female condom is less likely to cause urethritis or cystitis if its outer ring is fixed.

4. Usually, unintended pregnancy brings serious physical and psychological harm to women. Therefore, women pay more attention to the preventive measures of pregnancy. The female condom puts decision-making power and initiative in the hands of the woman, saving her from having to rely on her partner to wear a male condom to prevent pregnancy.

However, until today, the recognition and usage rate of female condoms are still far below the expectations of experts, and the popularity is far lower than that of male condoms. The operation is complicated and the experience is not very good, which makes the media, doctors, and even women themselves avoid the female condom. At present worldwide, the market share of female condoms is only 1.6%.

Part of the reason for this is its difficulty the first few times it is used. In the prior art, the female condom made of polyurethane film or natural latex is a film pocket with one end closure, an elastic inner ring is placed at one end of its closure, and an elastic outer ring is bonded at the open end. During use, it is necessary to pinch the elastic inner ring with fingers, push the female condom into the vagina by hand, and allow the elastic inner ring to open by itself, which is neither hygienic nor guarantees that the operation will be successful once. Also, whether due to cultural reasons or physical inconvenience/discomfort, many women are not comfortable inserting their fingers into their vaginas to place a female condom into the vaginal area.

Therefore, in view of the above technical problems, it is ideal to design a culturally acceptable condom placement tool that allows women to easily place the condom into the vagina and feel comfortable.

Invention content:

In order to solve the above-mentioned technical problems, the present invention will provide an effective and comfortable compact female condom and a condom insertion device which effectively solves all the above-mentioned problems and makes the user feel comfortable during the whole process. It is easy to use, has low cost, has no side effects, and is convenient for the user to put the condom in a suitable position, so that the user feels very comfortable during the whole process.

The technical scheme of the present invention is that a female condom inserter (12) comprises two interlocking cylindrical tubes, an inner tube (20) and an outer tube (30), and the inner tube (20) can be inserted into the outer tube (30) ) to slide back and forth freely. The diameter of the outer cylinder (30) is slightly larger than that of the inner cylinder (20), so that the inner cylinder (20) can freely slide back and forth in the outer cylinder (30). The top opening (32) of the outer cylinder (30) has hemispherical smooth surfaces (33) of several petal-like structures.

Further, there is a frame (38) on the bottom of the outer cylinder (30) to make it easier for the user to hold the inserter. There are several grooves (36) on the outer surface of the bottom of the outer cylinder (30) to make it easier for the user to grasp the outer cylinder of the inserter with two fingers of one hand. The top opening (32) of the outer cylinder (30) has hemispherical smooth surfaces (33) of several petal-like structures. When the outer cylinder (30) is pushed into the vagina, the hemispherical smooth surface (33) of the petal-like structure should be strong enough to maintain its original shape and flexible enough to allow the female condom to pass through easily. When no longer pushed inward, the hemispherical smooth surface (33) of the petal-like structure should resume its original shape and position.

Further, the inner cylinder (20) is completely hollow, or partially hollow, for example, the upper half of a cylinder is hollow or other shapes. The inner diameter of the inner cylinder (20) is slightly smaller than that of the outer cylinder (30), so that the inner cylinder (20) can freely slide back and forth in the outer cylinder (30). In order to ensure that this sliding movement is smoothly transmitted, there are two or more convex cylindrical protrusions (23) on the outer surface of the inner cylinder (20). The diameter of the inner barrel (20) may be the same diameter, or the diameter of the inner barrel top (22) may be slightly smaller than the rest of the inner barrel. Near the top of the outer surface of the inner cylinder (24), several small protrusions are engaged with several grooves (36) on the outer surface of the bottom of the outer cylinder (30) to prevent the inner cylinder (20) from slipping out of the outer cylinder (30) ). There is a border (28) at the bottom of the outer surface of the inner cylinder to make the inner cylinder easier to hold. There is a small protrusion (26) near the bottom of the outer surface of the inner cylinder to prevent the inner cylinder (20) from being pushed into the outer cylinder (30) too deep, so that the inner cylinder (20) can be easily connected with the outer cylinder (30) Detach or slide away. For the embodiment that the inner cylinder is hollow or partially hollow, a series of protrusions 29 are arranged on the inner surface of the inner cylinder to prevent the outer ring of the condom from being pushed into the inner cylinder too deeply.

Further, the inner cylinder (20) and the outer cylinder (30) are made of flat and soft materials, such as rubber, plastic, or cardboard with a smooth coating.

Inserts are available in various diameters and lengths to accommodate women of different sizes, personalities and personal preferences.

The female condom (14) comprises a thin soft sheath (46), and one end of the sheath is closed, that is, an inner ring (42) is arranged in the closed end (43) of the sheath. In order to prevent the open end from easily slipping into the vagina during use, an outer ring (44) is arranged on the open end. The condom cover body (46) is made of thin, soft and not easily cracked material.

Compared with the length of the inserter outer cylinder (30), said inner ring (42) has a relatively large diameter, if the diameter of the inner ring (42) is too large to be inserted into the outer cylinder of the inserter, the condom The inner ring (42) of the inner ring (42) may need to be folded several times, so that its size is suitable, can be inserted in the inserter (12). The inner ring is folded one or more times to fit most or all of it into the top of the outer barrel (30). At the same time, in order not to pull too many openings of the condom, the closed end (43) of the condom inner ring (42) and the condom cover body is folded several times and then extruded into a thin and long shape and put into the outer cylinder (30) the top of. In addition, the closed end (43) of the condom body should be folded together with the inner ring (42) so that once the inner ring (42) is released from the outer barrel (30), it can be closed without significantly pulling the outer ring (44). It can be opened very easily in the condom body (46). Preferably, the inner ring does not substantially change shape when released from the injector and retains its original shape to a large extent after being stretched and placed in the injector for a prolonged period of time. Outer ring (44) is very flexible, can be condom cover body (46) itself, also can be designed into different shapes such as triangle, belt shape or petal shape, preferably can keep its original shape basically after being released from inserter. The inner tube top (22) is positioned at the outer tube bottom (36), and when the cylindrical shape of the inner ring is pushed out of the inserter, the inner ring (42) of the condom will be ejected at the first time.

The outer ring (44) is also extruded into an elongated shape, and passes through the top opening (22) of the inner tube (20), so that part of the outer ring (44) is positioned in the inner tube (20), and the remaining condom cover body and The outer ring is rolled up so that the top opening (22) of the inner tube is close to the outer ring (44) to prevent the outer ring (44) from sliding around.

The using method of this device, its steps are as follows:

1) Put the female condom (14) into the inserter (10), fold the inner ring (42) of the condom and the closed end (43) of the condom body (46) several times, and squeeze it into a thin and The long shape is put into the top of the outer cylinder (30), and the outer ring (44) is also extruded into an elongated shape, and passes through the top opening 22 of the inner cylinder, so that part of the outer ring (44) is located in the inner cylinder (20), Make the inner cylinder top opening (22) close to the outer ring (44) to prevent the outer ring (44) from sliding around;

2) Place the inserter (10) equipped with the female condom (14) at the entrance of the vagina (120), as shown in Figure 6;

3) Grab the bottom of the outer tube (36) and slowly push the condom inserter into the vaginal area until the outer tube (30) is pushed into the middle of the vagina (140), as shown in Figure 7;

4) Then while holding the bottom of the outer cylinder (36), slowly push the bottom of the inner cylinder (28), the outer ring (44) pushes the inner ring (42) out of the inserter (12), and passes through the top of the outer cylinder ( 33) Enter the back of the vagina (160); as shown in Figure 8;

5) Since the space at the rear of the vagina is larger, the closed end (43) of the inner ring (42) and the condom will expand to the rear of the vagina. At this point, the outer cylinder (30) is mostly overlapping the inner cylinder (20). Grasp the bottom of the outer cylinder (36) and slowly remove the condom inserter (10) from the front of the vagina. Due to the pulling force of the inner ring (42) and the sleeve body (46), the outer ring (44) is pulled out of the inserter (10), as shown in Figure 9;

6) The outer ring (44) is partially or completely suspended outside the vaginal opening (120), as shown in Figure 10;

7) Pull the outer ring (44) out of the vaginal opening (120) completely, and straighten it so that it is evenly distributed on the vaginal opening, as shown in Figure 11;

The user uses this inserter (10), similar to a conventional tampon inserter, and pushes the inner ring (42) of the female condom comfortably into the user's vagina by pushing the inner barrel (20) , without requiring her to insert her hand into her vagina. Since female users are very familiar with the use of the tampon inserter, such a design can be easily adopted by female users. It is easy to use, convenient, cost-effective, has no side effects, and is convenient for users to put the condom in a proper position, so that users feel very comfortable during the whole process.
