Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an auxiliary tool for a condom. More specifically, the present invention relates to a condom auxiliary tool for preventing sexually transmitted diseases and dropouts of condoms.

[0002]

2. Description of the Related Art Conventionally, condoms have been known as a means for preventing sexually transmitted diseases. Condoms wear male genitals to prevent contraception and sexually transmitted diseases. Condoms are an effective means of preventing sexually transmitted diseases. However, if the condom falls out due to improper attachment to the penis or improper usage (such as wearing a condom when the male genitalia is wet, intercourse during contraction of the penis after ejaculation, or contraction of the penis), Condoms may remain in the vagina. In a recent study conducted by the Japan Family Planning Association Clinic, among the cases requiring emergency contraception,
About 20% was due to the condom dropping out or the condom remaining in the vagina. As an auxiliary tool for preventing the condom from falling off, a cylindrical ring is known which is mounted on the condom and holds the condom at the base of the penis. As a ring for preventing the condom from falling off,
Known are cylindrical ones made of rubber and those disclosed in Japanese Patent Application Laid-Open No. 07-231905.

[0003]

The conventional ring and the ring shown in Japanese Patent Laid-Open No. 07-231905 have only the effect of preventing the condom from falling off, and sexually transmitted condom on the part covered with the condom. It reduces the infection rate of the disease and is ineffective against infections from other parts. Also, during sexual intercourse, skin may rub against parts other than the genitals, resulting in small scratches. And there is a possibility that bacteria and viruses will be infected from the wound. In particular, pubic hair grows on the part that is rubbed during sexual intercourse, and there is a high possibility that scratches will occur if the parts rub strongly. Condoms, whose main purpose is to prevent contraception and prevent sexually transmitted infections, can fall out by themselves. In addition, even with a conventional ring that is a device for preventing the fall of a condom, the scope of protection against sexually transmitted diseases (sexual infections around the vulva) is narrower than when a condom is used. The present invention is intended to eliminate the problems of falling off and folding in the middle of using a condom.

[0004]

According to the present invention, by providing a thin film on a ring, it is used in combination with a condom which has a narrow protection range for sexually transmitted diseases, and by covering with a thin film of a certain size, protection is provided only by the condom. It protects against sexually transmitted diseases such as external-negative herpes that can not be treated and gargles. In addition to the ring effect, it can be expected to prevent center bending. The present invention takes the following means to prevent infection of sexually transmitted diseases. That is, as described in claim 1, a condom auxiliary tool to be mounted on a condom, wherein a ring for inserting the condom and a sheet are connected to the periphery of the ring to prevent contact with the genitals and the peripheral part of the genitals. .

As described in claim 2, the ring is made of a rubber-like substance having elasticity and extensibility and a hardness of 4 to 30 or a swollen elastomer.

According to the third aspect, the outer diameter of the ring is 50 mm or less, and the width of the sheet connected to the peripheral edge of the ring is 10 to 50 mm.

According to a fourth aspect of the present invention, the inner peripheral surface of the ring which comes into contact with the condom is a circumferential surface parallel to the extending direction of the condom.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described with reference to the drawings. 1 is an overall perspective view showing the configuration of a condom auxiliary tool, FIG. 2 is a front view of the same, FIG. 3 is a sectional view taken along the line AA in FIG. 2, FIG. FIG. 6 is a partial side sectional view showing a positional relationship between the human body and the condom assisting device during sexual intercourse, FIG. 6 is a partial side sectional view showing a condom wearing configuration using the condom assisting device, and FIG. 7 is an inner peripheral surface of the condom assisting device. FIG. 8 is a view showing an example in which a slip stopper is provided, FIG. 8 is a perspective partial cross-sectional view showing another example of a condom assisting tool, and FIG. 9 is a view showing another embodiment of the seat portion of the condom assisting tool.

First, the structure of the condom auxiliary tool will be described with reference to FIGS. 1 to 3. Condom aid 1
Is composed of a cylindrical ring 2 and a doughnut-shaped sheet 3. The inner peripheral surface of the ring 2 is configured parallel to the opening direction as shown in FIG. The front surface and the rear surface are also flat. Thereby, the contact surface between the condom auxiliary tool 1 and the condom can be made large. By configuring the inner peripheral surface of the ring 2 parallel to the extending direction of the condom, the contact efficiency between the ring 2 and the condom can be increased within a certain width.

That is, the friction surface between the ring 2 and the condom can be increased. Furthermore, the condom, which is held down by the ring 2, is held down on the penis. Then, the condom can be pressed down in a sufficient area at the base of the penis. As a result, the frictional force generated between the ring 2 and the condom and between the condom and the penis can be improved, and the condom can be prevented from falling off.
Moreover, since the area for tightening the condom and the penis can be increased by the ring 2, the force for tightening the penis can be reduced by the ring 2 per unit area. Therefore, it is possible to prevent the condom from falling off while reducing the force, and it is possible to eliminate the discomfort caused by wearing the condom auxiliary tool.

A seat 3 is connected to the outer circumference of the ring 2. The seat 3 is thinner than the ring 2. In the embodiment shown in FIGS. 1 to 3, the seat 3
The outer peripheral portion of is formed in a circular shape, and is formed at a uniform distance from the ring 2. Further, the seat 3 has a structure in which the side portion of the ring 2 is connected to approximately the center in the front-rear direction.
By making the sheet 3 thin, the sheet 3 can be made more flexible than the ring 2. As a result, the close contact with the body is increased and the sheet 3 is easily deformed along the body.

The condom auxiliary tool 1 is composed of a rubber-like substance having elasticity and extensibility or a swollen elastomer. As rubber, natural rubber,
It is possible to use various synthetic rubbers such as silicone rubber and urethane rubber. The swollen elastomer may be water, silicone oil, or the like that does not affect the human body even when it comes into contact with the skin or mucous membranes. And the hardness of the substance which comprises the condom auxiliary | assistant tool 1 uses the substance which becomes 4-30 (JIS-A). The outer diameter of the ring 2 is 50 mm or less, and the width of the sheet 3 connected to the peripheral portion of the ring 2 is 10 to 5 mm.
It is set to 0 mm. With such a configuration, it is possible to reduce a feeling of strangeness when the condom auxiliary tool 1 is attached, and it is possible to reduce adhesion of body fluid. The condom auxiliary tool 1 can reduce the infection rate of sexually transmitted diseases through body fluids by making it larger than the size of the female vulva. By setting the outer diameter of the ring 2 to 50 mm or less, the conformability of the seat 3 to the body can be secured. The seat 3 has a uniform width around the ring 2, and can be easily mounted without checking the top and bottom when mounting the condom auxiliary tool 1.

The ring 2 is inserted into a penis fitted with a condom. Then, the ring 2 is attached to the penis with the inner circumference thereof widened. The condom is pressed against the penis by the restoring force of the ring 2 to prevent the condom from falling off. The ring 2 is made thicker than the sheet 3, and in this embodiment, it is about 10 mm thick.
It has a thickness of mm.

Next, the mounting state of the condom auxiliary tool 1 will be described with reference to FIGS. The condom auxiliary tool 1 is attached to the penis from above the condom 4. The condom 4 is prevented from falling off the penis at the base of the penis. The ring 2 prevents displacement of the condom 4 from the penis.
Then, the seat 3 is connected to the ring 2 mounted on the condom 4. This makes it possible to cover a certain range with the sheet 3 centering on the penis.
A condom 4 is attached to the penis, a ring 2 is in close contact with the condom 4, and a sheet 3 is formed integrally with the ring 2. This can prevent the condom 4 from falling off and remaining in the vagina. Further, since the sheet portion 3 covers the peripheral portion of the penis, infection due to contact with body fluid or skin can be suppressed.

Next, the cushion effect of the seat 3 will be described. As shown in FIG. 5, the seat 3 connected to the ring 2 is located in front of the pubic symphysis 6 of the man or in the direction of the penis. The sheet 3 has a body fluid adhesion,
It has a cushioning property while suppressing the infection of bacteria and viruses. That is, on the male side, since the cushion is attached near the pubic bone joint portion 6, it is possible to protect the skin in front of the pubic bone joint portion 6 where strong pressure is generated during sexual intercourse. Further, since the sheet 3 is located between the male and female skins, it is possible to suppress the rubbing between the skins and the occurrence of scratches near the pubic area.
In the state shown in FIG. 5, the seat 3 of the condom assisting tool 1 is located between the pubic bone joint 5 on the female side and the pubic bone joint 6 on the male side. As a result, it is possible to avoid pressing the skin and rubbing the skin between the pubic bone joint 5 on the female side and the pubic bone joint 6 on the male side. That is, the condom auxiliary tool 1 can suppress the occurrence of scratches during intercourse.

Next, a method of mounting the condom 4 using the condom auxiliary tool 1 will be described with reference to FIG. Figure 6
6A is a diagram showing a state where the condom 4 is ready to be worn by the condom auxiliary tool 1, and FIG. 6B is a diagram showing a state in which the condom 4 is being worn by the condom auxiliary device 1.
FIG. 3C is a diagram showing a state where the condom 4 is completely attached by the condom auxiliary tool 1. The condom auxiliary tool 1 is mounted by mounting the condom 4 on the penis 7 and then inserting the penis 7 mounted on the condom 4 into the central hole of the ring 2. Besides this, a condom aid 1
Therefore, the condom 4 can be attached.
As shown in FIG. 6A, the condom 4 is placed on the glans of the penis 7. Then, as shown in FIG. 6B, the condom auxiliary tool 1 is pushed down while passing through the penis 7. As a result, the condom 4 is attached to the penis 7 while the condom auxiliary tool 1 holds down the rolled-up portion of the condom 4. Then, by pushing down the condom auxiliary tool 1 to the root portion of the penis 7, the condom 4 is attached at the same time as the condom 4 is attached, as shown in FIG. 6 (c). Since the condom 7 is attached by the condom auxiliary tool 1, the condom 7 is not damaged by the nail of the hand when the condom 7 is attached, and the probability of contraception and infection can be reduced.

In the condom auxiliary tool 1, the inner peripheral surface of the ring 2 is formed perpendicular to the opening direction as described above. However, in order to improve the condom holding ability of the condom auxiliary tool 1, as shown in FIG. 7, it is possible to form a groove or the like on the inner peripheral surface of the ring 2. FIG. 7A is a perspective partial cross-sectional view showing the configuration of a condom auxiliary tool 1 having an arcuate groove, and FIG. 7B is a condom auxiliary tool 1 having a groove parallel to the opening surface of the ring 2. FIG. 7C is a perspective partial cross-sectional view showing the configuration, and FIG. 7C is a perspective partial cross-sectional view showing the configuration of the condom auxiliary tool 1 having zigzag grooves parallel to the opening surface of the ring 2. By thus forming the groove on the inner peripheral surface of the ring 2, the holding ability of the condom is improved and the condom is prevented from falling off or remaining in the vagina.

As a constitution of the condom auxiliary tool, as shown in FIG. 8, it is possible to form a sheet 3 at an end portion in the opening direction of the ring 2. This makes seat 3
Seat 3 with the side facing the male body
This makes it easier to attach the to the male body. And
The condom auxiliary tool 21 facilitates covering the genital area.

The shape of the seat 3 is not limited to a circular shape, but may be configured as shown in the condom auxiliary tool 22 of FIG. In the condom auxiliary tool 22, the sheet 3 has a heart shape. In the embodiment shown in FIG. 9, the seat 3 extends diagonally upward and to the left above the condom auxiliary tool 22. With this configuration, it is possible to sufficiently cover the pubic bone joint on the male side and the upper body side of the pubic area. And, it becomes possible to reduce the infection rate of sexually transmitted diseases.
