SOLUTION: Two tube type cases made of soft material such as natural rubber, silicone rubber, plastic or the like are stacked in layer, partially made adhere to each other to form a case part 1, and many ring-like projecting parts 2 which are deformed and projected like a semi-cylindrical ring-like groove, are formed on an outer layer on the case part, and a ring-like projecting part is formed on the inner layer thereof. Cavities are partitioned by the ring-like projecting parts 2, and the outer layer and the inner layer are put in the non- adhering state to connect the interiors of the respective ring-like projecting parts with each other to form a connecting pipe 4, which is connected to an air feed device 7 incorporating an air tank 6, a battery-driven air feed pump and a pressure regulator through an air feed pipe 5. At the time of use, air is fed to the respective ring-like projecting parts 2 to be expanded and deformed, thereby obtaining a favorable feeling of pleasure.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contraceptive skin system capable of arbitrarily changing the degree of depression on the inner and outer surfaces.

[0002]

2. Description of the Related Art Conventionally, a contraceptive skin (condom) composed of a test tube-shaped thin film container made of rubber or the like has been used for the purpose of contraception and prevention of sexually transmitted diseases.

[0003]

The conventional ordinary skin can be expected to have a sufficient effect of contraception and prevention of sexually transmitted diseases if it is used with certainty, but in practice, its use is often avoided. The reason is that the wearing is troublesome, but the main reason is that the sensation is weakened. If pleasure does not diminish, but rather increases, it will be actively used, and the effects of contraception and prevention of sexually transmitted diseases, which are the original purposes, will be greatly exerted, and the explosion of the population on the earth in the future will occur. And prevent the shortage of food and other resources, and increase the effect of preventing the increase of patients with sexually transmitted diseases such as AIDS. Whether it can not be increased can be analyzed as follows. Most of the sexual sensations that occur during sexual activity are, as is known in sensory physiology, etc., a large number of minute tactile / vibratory sensory receptors present in the foreskin of the male genitals (the glans penis) and the mucous membrane of the female genitals (the vagina, etc.) It occurs with the stimulus that occurs. These receptors have no sensation when fully pressurized so that they are not stimulated when receiving a large amount of water pressure or air pressure during bathing or diving into the deep sea. A small pressure difference distribution occurs on the foreskin and mucous membrane surface, and the foreskin and mucous membrane are deformed, and the receptors are also stimulated when deformed. (For example, when a single hair is brought into contact, the foreskin surface is deformed and a tactile sensation is generated). And if the deformation persists, the sensation immediately disappears (adaptation phenomenon).
The deformed part is constantly moved, and continuous tactile stimulation and vibration stimulation are obtained. It is considered that a tactile sensation occurs when the deformation change occurs in a relatively long cycle, and a vibration sensation occurs in a short cycle. (If the deformation is persistent, a pressure sensation is generated by the pressure receptor.) Also, if this deformation gradient change (curvature) is abrupt as in the case of contact with a needle, the pain receptor is stimulated. ,
If it is too slow, it does not produce a feeling, so it must be a moderate value. For example, even when rubbing on a smooth, low coefficient of friction surface such as a glass cylinder surface with lubricating oil, little deformation of the receptor occurs and no sensation occurs. The biggest cause of the conventional skin reducing the sensation is that the fine unevenness of the genital surface of the opposite sex is covered with a rubber film and smoothed, and conventionally, thin products using soft rubber are good quality products. The reason is that it is possible to comparatively faithfully reproduce the fine protrusions on the surface of the isomer. Even if a good quality skin is used, if a lubricating liquid such as silicone oil is not used enough, a rubber film adheres to the foreskin surface and the like,
As a result, the outermost layer of the foreskin and mucous membrane is thickened, and no fine deformation occurs, and the feeling is reduced. (However, a moderate amount of slippage occurs between the rubber surface and the foreskin or mucous membrane surface,
If the withdrawal is repeated rapidly and the vibration occurs, the sexual feeling becomes active, but pain is likely to occur. As described above, in order to generate a pleasant sensation, it is necessary to use an appropriate lubricating liquid so that the foreskin, the mucous membrane and the receptors inside the foreskin can undergo a moderate temporal deformation change. . For that purpose, there is a moderate concave protrusion on the plow surface,
Genital foreskin and mucosal surfaces must be pressurized with moderate pressure. (If the pressurization is too small, the foreskin or mucosal surface cannot be deformed to the extent necessary to generate the minimum sensation (subthreshold stimulation that does not reach the threshold).) The present invention solves such a problem. The aim is to obtain a skin system that can be used.

[0004]

Means for Solving the Problems Two test tube-shaped containers made of a thin flexible rubber or plastic are stacked, and the two membranes are partially adhered at a number of places to form a number of continuous small cavities. , A container with a number of small concave protrusions on the inner and outer surfaces, a long and thin flexible air supply pipe connected to the cavity, and a free end of the air supply pipe connected to an air supply device that can be set to an arbitrary pressure. This is a basic configuration of the present invention. After sufficiently applying the lubricating liquid to the inner and outer surfaces of the container, attach it to the male genitalia, insert it into the female genital, activate the air supply device, and send air selected at a fine appropriate pressure into the container, A concave projection is formed on the inner and outer surfaces of the axle, and moderate pressurization is applied to the amphoteric genitalia, so that the deformation of the vibratory and tactile receptors during sexual activity can occur moderately, and the best pleasure is achieved. To be obtained.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of a contraceptive skin system with variable concave protrusion according to the present invention. FIG. 2 is an enlarged left side view of a part thereof. 1 is a test tube-shaped container having a thickness of 0.02 to 0.5 mm, a horizontal length of 20 cm and a diameter of about 3 cm, which is made of a flexible material such as rubber, urethane resin or other plastics. A container part formed by laminating two layers and adhering them in many parts. Reference numeral 2 denotes a number of annular projections formed by deforming and projecting the outer layer into a semi-cylindrical annular groove having a radius of about 5 mm. (A recess is formed between the respective annular projections.) Reference numeral 3 denotes an annular projection corresponding to 2 provided on the inner layer.
As a result, a cavity having a diameter of about 10 mm is formed. The right annular protrusion has a slightly smaller inner diameter and a slightly larger outer diameter, and has a function of preventing falling off from male genitals and a function of preventing entry into female genitals. Reference numeral 4 denotes a communication pipe formed by disbonding an outer layer and an inner layer connecting the insides of the respective annular protrusions. The communication pipe does not appear in the drawing, but exists below the container portion 1. Reference numeral 5 denotes an air supply pipe made of a flexible rubber or plastic having a thickness of about 0.2 mm and a length of about 1 m, which is continuous with the inner space of the annular protrusion 2. Reference numeral 6 denotes an air tank formed by increasing the diameter of a part of an air supply pipe, and the end thereof is fitted into a nozzle 10. Reference numeral 7 denotes an air supply device in which a battery-driven air supply pump, a pressure regulator, and the like are built in a rectangular parallelepiped box. 8 is a push button type start switch. 9 is
Pressure setting knob connected to the pressure regulator in the air supply device. 10
Is a nozzle connected to a pump in the air supply device 7.

Next, the usage and operation will be described. When the switch 8 is turned off, the current supply circuit to the internal pump is stopped, the valve connected to the nozzle 10 is opened, and the air in the tank 6, the air supply pipe 5, and the annular protrusions 2 and 3 is exhausted. Apply enough silicone oil or other lubricating liquid to the inner and outer surfaces of the container 1, cover the male genitalia, insert it into the female genitalia, and press the switch 8 to activate the air supply pump, and the air is discharged from the nozzle 10 to the tank. 6 → pneumatic pipe 5 → annular projections 2 and 3,
After reaching the communication pipe 4, the tank 6, the annular projections 2 and 3, the communication pipe 4, and the like expand to the state shown in the figure. The ring-shaped protrusion 2 deforms the female genitals from the inside in a waveform, and the ring-shaped protrusion 3 deforms the male genitals from the outside in a waveform. If the degree of deformation is too large, turn knob 9 to lower the air pressure,
The annular projections 2 and 3 are reduced. If the difference between the diameters of both genitals is large and the degree of concave deformation of the genitals is too small, such as when a woman is a prolific woman, turn the knob 9 to increase the air pressure and increase the degree of expansion of the annular protrusions 2 and 3. You just need to increase it. By performing sexual behavior, the deformed part moves in the long axis direction of the genitals, and good pleasure can be obtained. (The container part 1 also expands and contracts in the left and right directions to some extent, contributing to the movement of the deformed part.) When the air in the annular protrusion is removed due to the sexual behavior, the air flows in the air supply pipe 5 backward, It is stored in the tank 6 and serves as a buffer for an excessively large change in the atmospheric pressure due to a change in the volume between the hermaphrodites. After the sexual activity, the switch 8 is turned off, the tank 6 is extracted from the nozzle 10, and discarded together with the container 1 and the air supply pipe. , Without using the air supply device 6, blow air into the mouth from the end of the protein 6, clip the end of the tank,
The tank may be tied in a round knot to prevent air leakage. At the end of the tank 6, a check valve made of a rubber pipe having a length of several centimeters that has entered the tank may be attached, air may be blown through the mouth through a straw, and the straw may be pulled out to maintain a constant pressure. . A choke valve is inserted at the boundary between the tank 6 and the air supply pipe 5 so that the pressure in the annular projections 2 and 3 increases or decreases slightly in the tank 6 or the valve is moved from the tank to the air supply pipe. Ventilation is easy, but the reverse is possible by inserting an incomplete check valve with a large resistance or a check valve of the opposite, so that the pressurization of the danger accompanying sexual activity may take some time. A special sexual sensation that increases or decreases with a delay may be generated. Air may be supplied to the tank 6 by a hand pump used for a sphygmomanometer or the like. Attach stakes at intervals of 10 cm to pillars with a height of 1 to 2 m and connect the end of tank 6 to the nozzle at the lower end of a 1 l hot water container with a built-in heater with a temperature controller to heat it to about 40 ° C. Container at any height,
It is also possible to suspend the suspension and send warm water of an appropriate water pressure into the inner space of the annular protrusions 2 and 3. The air supply device 7 is expanded, and an actuating plate for appropriately sandwiching or loosening the tank 6 from the left and right by a motor drive is provided to cause air pressure fluctuation at a cycle of about 1 to 10 Hz, so that the inside of the annular protrusions 2 and 3 May be changed to increase the pleasure. In this case, the air pressure fluctuation may be obtained by the reciprocating motion of the piston of the piston pump in the air supply device 7.
When air is separately supplied to the inner space of the ring-shaped protrusions 2 and 3 and the inner space of the middle layer (described later), a pressure adjustment period adjustment knob, a maximum pressure setting knob, a minimum pressure setting knob, and the like are respectively provided. It is also possible to provide a variable pressure cycle and amplitude that can be arbitrarily selected. Simultaneously with the short-period pressure fluctuation, the amplitude is set
A knob that changes with a trend of about 0 seconds may be provided. The inside of the annular protrusion 2 is divided into two cavities that do not communicate with each other,
The air pressure may be changed at different cycles by connecting to different air supply devices. (The same applies to the ring-shaped protrusion 3.) A round filter is provided in the air supply device, these optimum set values are stored, and the next time, one-touch operation may be performed with this set value. . An indicator indicating the pressure in the air supply pipe 5 may be provided in the air supply device 7. Alternatively, a scale consisting of a transparent plastic belt with a width of 1 cm and a width of about 1 mm is provided in the middle of the tank 6, with one vertical line drawn around it and about 3/4 circumference. , Glue one end to the opposite side of the vertical line of the tank,
If the degree of expansion of the tank changes, the point of coincidence between the vertical line and the eye may change so that the atmospheric pressure can be measured. The air pressure applied to the cavities such as the annular projections 2 and 3 is usually higher than the blood pressure.
It is desirable to set it to a little lower around 100 mmHg. In these cases, the air supply pipe 5 is made of a slightly hard material and its surface is covered with urethane foam or the like so that the air pressure fluctuation can be transmitted faithfully, so that the feel of the air does not deteriorate. Due to the expansion and contraction of the cavity due to the atmospheric pressure fluctuation, the container part 1 expands and contracts in the longitudinal direction as well, thereby enhancing the tactile / vibration sensation stimulating action. The expansion and contraction in the axial direction can be increased. For example, if the annular protrusion is formed as a large number of protrusions having a minor axis of 3 mm, a major axis of 5 mm, and a length of about 10 mm and inclined at about 60 °, if the internal pressure is low, the surrounding area is pressed, and the inclination of the projections increases. , The tip moves in the long axis direction of the container portion 1. (If the inclination direction of the adjacent protrusion is reversed, the relative movement distance increases.) A cavity having a diameter of about 3 cm is provided in the closed end of the container portion 1, and the internal pressure is changed by an independent air supply system. Alternatively, the entire container may be reciprocated in the long axis direction. The cavity formed by the annular protrusions 2 and 3 is formed into two parallel single-layer coils as described later,
A constant air pressure may be applied to one coil and a variable air pressure may be applied to the other coil, so that the container 1 expands and contracts in the long axis direction by the latter change. Alternatively, the cavity may be formed into a large number of zigzag shapes that extend 2.3 cm diagonally from the large cavity of the opening portion and bend. Good.

Next, an outline of a method of manufacturing the container 1 will be described. On the outer surface of a test tube mold having a length of about 30 cm and a diameter of about 5 cm, a groove corresponding to the annular protrusion 3 and the communication pipe 4 is carved,
Around this, a rubber film for the inner layer of the test tube-shaped container portion 1 was spread and covered (the air in the groove may be evacuated by a vacuum pump through a vent hole provided in the mold) and applied on a flat plate. Roll it over the rubber glue and attach it to the area other than the depression. A metal cylinder with an inner diameter of 5.5 cm and an outer diameter of about 6.0 cm
Cover with a test tube type rubber film for the outer layer,
If the tip of the outer layer portion is brought into contact and the metal cylinder is moved in the long axis direction of the inner layer portion, the outer layer portion is overturned, is overlaid on the inner layer portion, is adhered with rubber glue, and the annular protrusion 2, A communication tube 4 and a cavity surrounded by 3 are formed. Before covering the metal cylinder with the outer layer, a small hole is made in a part of the outer layer, the end of the air supply pipe 5 is passed through, and the outer surface of the inner layer is attached to the outer surface of the inner layer with a rubber paste, or If the end is adhered and the outer layer is covered, the air supply pipe 5 can be attached. If the material of the inner layer and the outer layer is thermoplastic, after covering the outer layer, air is blown in at a low pressure from the air supply pipe 5 to prevent contact with the cavity, and is pressed from the surroundings with a heating mold or high frequency heating. You may. A thermosetting adhesive may be applied to the outer surface of the inner layer, covered with the outer layer, and then bonded by heating. A rubber belt may be applied to a long rubber belt having a width of about 1 mm and a thickness of about 0.1 mm, and the mold may be wound around the inner layer film in a coil shape, and the outer layer film may be covered thereon, and the two may be bonded. (The inner space becomes a coil shape as described later.) After bonding, a small amount of silicone oil or another anti-adhesion agent may be fed through the air supply pipe 5 to prevent the inner surfaces of the annular protrusions 2 and 3 from adhering. . A test tube-shaped inner layer film made of thermosetting material such as rubber to which sulfur powder has been added is coated with an anti-adhesive agent only on the parts that are not to be adhered to the outer surface, and the outer surface is covered on those outer surfaces and heat-cured. May be. A large amount of lubricating liquid may be applied to the inner and outer surfaces of the container portion 1 and then, together with the vicinity of the air supply pipe 5, may be rolled up from the opening to reduce the apparent volume and stored.

In the above embodiment, various other design changes are possible. The outline is described below. The outer diameter of the test tube-shaped rubber film of the outer layer constituting the container part is made slightly larger than the free diameter of the inner layer, and both are adhered in an expanded state of the same diameter, and when the air is expanded by air supply, a ring-shaped protrusion is formed. In both 2 and 3, the material rubber may be expanded at substantially the same magnification. The inner and outer rubber films may be formed in advance by forming grooves like the ring-shaped protrusions 2 and 3 and then bonded together. The radius of the grooves of the annular protrusions 2 and 3 may be arbitrarily changed within a range of about 1 to 10 mm. A large number of hemispherical small protrusions having a radius of about 1 mm may be protruded from the surfaces of the annular protrusions 2 and 3 to enhance the tactile stimulation. A single-layer coil is wound around a rubber thread with a diameter of about 0.1 mm or a rubber belt with a thickness of about 0.1 mm and a width of about 1 mm, and a number of small protrusions with a diameter of about 0.1 mm and a length of about 1 mm protruding from the surface. May be adhered to enhance the tactile sensation. The thickness of the rubber film for the inner and outer layers of the container portion 1 may be changed depending on the portion, and the surface may have a sine waveform having a wavelength in the major axis direction of 1 mm and an amplitude of about 0.5 mm. (If the waveform is a square wave or the like, pain will be generated.) The sizes of the ring-shaped protrusions 2 and 3 may be changed in a wave shape in the circumferential direction. The distance between each ring-shaped protrusion is 1 mm to several c
It can be arbitrarily selected within a range of about m. The left and right width of the communication pipe 4, the width in the circumferential direction, the number provided for each circumference, and the like can be arbitrarily selected. The shape and size of the bond between the inner and outer layers,
The distribution state or the like can be arbitrarily selected, and the shape and size of the concave protrusions generated on the inner and outer surfaces of the container portion 1 can be arbitrarily selected. The communication pipe 4 may be omitted, and the cavity formed by the annular protrusions 2 and 3 may be formed into one continuous single-layer coil. In that case, the cavity is 1
In the case of the book alone, the distance of the cavity from the opening of the container portion 1 to the tip becomes longer, and the circulation of air becomes worse. Therefore, one thick annular cavity connected to the air supply pipe 5 is provided near the opening,
Then start several narrow cavities in parallel,
May be reached in the form of a parallel coil. The size and shape of the annular protrusions 2 and 3 and the communication pipe 4 may be variously changed depending on the location in the container portion 1. These are manufactured by an automatic device using a servomotor, an air cylinder, and the like. Polyvinyl alcohol or the like is added to the rubber latex in a range of about 10 to 80% to form a rubber film containing a water-soluble substance.
And it may be made to dissolve in water after several hours even if it is flushed to a flush toilet or the like. Rubber latex solidifies in an acidic environment and dissolves in an alkaline environment.Therefore, a rubber film is made of a material with a low degree of vulcanization and added with an acidic substance, and then enters a flush toilet and dissolves in an alkaline environment. You may.

[0009] An adhesive is partially applied to the outer surface of the test tube type rubber film as the middle layer, and the test tube type rubber film as the outer layer is covered,
The container may be turned upside down, partially coated with an adhesive, covered with a test tube-shaped rubber film for the inner layer, and formed into a three-layer container portion 1. In this case, only one air supply pipe 5 may be attached, holes may be made in some places in the middle layer, and a common air pressure may be applied to the inner and outer cavities, or the air supply pipes may be attached to the inner and outer cavities, respectively. A separate air supply device may be provided so that the internal and external air pressures can be arbitrarily changed. The middle layer may be made of a soft or hard foamed resin having a thickness of about 1 cm. In this case, the open ends of the rubber films of the inner layer and the outer layer are directly adhered to each other to prevent air leakage. Since the surface of the foamed resin has fine concave protrusions, in this case, an adhesive portion may be provided on the entire surface. Alternatively, the middle layer is made of a foamed resin, and the surface is provided with a thick rubber (or a freeze-dried product thereof) made of thick natural rubber, silicone rubber, polyvinyl alcohol containing a large amount of water, and natural rubber having concave protrusions on the surface. The inner layer and the harmful layer may be made of a material such as a product obtained by laminating a film, and the entire surface of the middle layer may be coated with rubber paste and the inner and outer layers may be bonded. Two test tube-shaped rubber membranes for the middle layer are stacked and bonded to each other at several places parallel to the long axis with several to ten or more discontinuous linear adhesive lines or a large number of discontinuous annular adhesive lines. Then, with one air pipe 5, the middle layer and the annular projections 2 and 3
Or the air may be supplied by separate air supply pipes, so that the overall thickness can be varied over a wide range. (It is easier to obtain the sensation if the pitch of the ring-shaped protrusions 2 and 3 is made finer and larger, but then the thickness of the entire container 1 becomes smaller. However, if the thickness of the middle layer can be increased or decreased, the thickness of the entire container 1 increases. It is also possible to put a test tube-shaped foamed resin between the middle layers and to bond the middle layer film to the inner and outer surfaces thereof. Air flows through the open cells, and the thickness changes according to the air pressure. This middle layer has an inner diameter of 40
mm and an outer diameter of about 42 mm. (Especially the opening is thickened or rounded,
Prevent pain sensation due to contact with the human abdomen. The middle layer may be a double layer bonded at the opening, and a small amount of the lubricating liquid may be put therein. Between the inner and outer middle layers, a large number of long-tilted rubber partitions of about 1 × 20 cm in the major axis direction are inserted,
When the air pressure in the middle layer is low, the partition wall falls down in one direction and the inner and outer layers are close to each other, and when the air pressure increases, the inner and outer layers are moved away, so that the inner diameter and outer diameter of the entire container part can be greatly changed. You may. The partition may be formed of a large number of ring-shaped flat rubber films having small air holes or a continuous coiled rubber film.

[0010] Rubber glue is applied to the entire rubber film for the middle layer, and the end is covered with a test tube-shaped holding rod whose right side is directed to the right side. From the left end (opening) of the membrane to the right end, stick the middle of the air supply pipe, wind it around it in a single-layer coil so as to surround the entire middle layer, and when it reaches the left end, overturn the integrated material And apply rubber glue to the entire middle layer on the surface,
The remaining part of the air supply pipe may be wound in a coil shape and attached so that the end of the air supply pipe reaches the end of the middle layer. Also in this case, two air supply pipes may be provided and wound around the inside and outside of the middle layer. The tip of the air supply pipe 5 may be divided into two parts and wound around the inside and outside of the test tube-shaped debris membrane. Place a circular rubber film of about 5cm in diameter on a horizontal table, place a metal cylinder of about 3cm in diameter with a release agent applied on its outer surface, stand it up, apply rubber to the long air pipe with closed end, and place it on the rubber disk May be wound into a single-layer coil to obtain an integrated product in which a rubber tube continuous coil is adhered to a rubber disk, and a product having substantially the same function as that shown in FIG. 1 may be obtained. This disc-shaped rubber membrane is omitted,
An inner layer test tube type rubber film may be covered on a metal cylinder, an air supply tube coil may be attached to the outer surface thereof, and an outer layer test tube type rubber film may be further covered.

A long rubber balloon-like rubber membrane having a diameter of about 3 cm and a length of about 40 cm, one end of which is closed, and the other end of which has a tubular outlet having a diameter of about 1 cm and a length of about 10 cm, and has an elongated bellows-like concave projection. Put a thin brush with rubber glue at the tip inside the blow port, apply rubber glue in a ring shape around the mouth of the balloon inside the balloon, pull out the brush, put it on the tip of a test tube type mold with an outer diameter of about 3 cm, If the balloon is covered from the closed end of the balloon so that the balloon is doubled, the inner surface of the closed end of the balloon comes in contact with the adhesive-attached portion when the balloon is over the outside of the mold, and stops. After the adhesive has hardened, remove it from the mold. After applying the lubricating liquid to the entire surface, blow an appropriate amount of air from the air outlet and tie the water outlet to stop air leakage.
With a little more than a centimeter, the inside is in a state where the rubber film is in close contact. Male genitals are inserted inside, and inserted into female genitals from the side of the mouth. (If the outlet is longer than 30cm and it is attached to the outer surface of the balloon with rubber glue, the end of the spout can be brought outside.) In this case, a long straight pipe with a diameter of about 5mm 3cm at the end of the 9
Put a 0-degree curved brush-type tube into the balloon from the outlet, and blow the air into the balloon while inflating the balloon appropriately. And apply rubber paste to the inside of the balloon in a coil shape,
After removing the tube, the tube may be covered with the mold and the inner surface of the balloon may be double-bonded in a coil shape. A variety of sizes may be provided to manufacture a group of products in which various amounts of liquids and gases that are hard to leak even after a long period of time are enclosed, so that air does not need to be blown when used.

In order to prevent the container portion 1 from detaching during sexual activity, a rubber thin film having a large number of ventilation micropores for evaporating perspiration similar to the skin with good touch, and pants that adhere to the body using elastic fibers are used. The container part 1 having a flange attached thereto may be joined to a hole formed in the container, the opening of which is appropriately inclined, and a male or a female may wear it and put it on the genitals for use. (The flange and pants may be made detachable with hook-and-loop fasteners or adhesive.) In that case, the pants may be pantyhose-type, or the back may be split vertically to open and close, and limbs, torso, etc. may be inserted from there. It may be a full-body clothing type equipped with a shirt that can do things. When minimizing the size of the pants, in the minimum case, only the belt ring to be fitted to the roots of both legs may be used. If you have erectile dysfunction due to diabetes or other problems, it may cause divorce, which is a serious problem. In order to cope with this, a container part 1 using a middle layer made of a semi-structural material having a thickness of about 1 mm may be attached to the above-mentioned pants so that at least a woman can be satisfied with sex. (However, as described above, if a vibration stimulus is applied due to atmospheric pressure fluctuation, even if you cannot erect, you can give a sexual feeling to the male genitals and ejaculate it.) The middle layer is made of two hard materials A gap of about 1 mm is formed between the two, and the two are joined at the opening, and a width of about 1 mm is formed on the inner surface of a test tube-shaped rubber film having a thickness of about 0.1 mm for forming the concave protrusion 2.
A long rubber belt with a thickness of about 0.3 mm and a thickness of about 0.3 mm is attached to the coil, only the opening is attached to the outer surface of the middle layer, and an air supply device is provided between the two. It expands greatly and extends in the longitudinal direction, and when decompressed, causes them to shrink and move. A rubber film similar to that of the container portion 1 is housed in the middle layer to serve as an internal rubber film, and the middle layer and the internal rubber film are joined only by their openings, and an independent air supply device is provided to the inside of the rubber film. , An air supply system connected to the opening in the inner layer of the middle layer is provided, a small hole is opened in the closed end of the inner layer of the middle layer, if the pressure in the inner layer of the middle layer is increased, the internal rubber film is pushed to the opening side, and if the pressure is reduced, the reverse occurs. With the internal rubber film filled with air at a moderate pressure, air with a higher pressure is sent into the middle layer and pushed back close to the opening, where the male genitals are inserted into the internal rubber film. , Then depressurize the inside of the middle layer, aspirate the male genitals and the inner rubber membrane into the middle layer, fill the cavernous body of the penis, erect it, fluctuate the middle layer pressure, change the degree of retraction, Fluctuates the internal rubber film pressure, causing tactile sensation and vibration It may be. (At the closed end of the inner layer, open a small hole that does not connect to the cavity in the inner layer, extend the inner rubber membrane to the end in the middle layer, and if the inner space of the middle layer is decompressed,
Male genitals are sucked into the internal rubber film, and with the pressure fluctuation,
The genital tip may be moved. If ejaculation does not occur even in this way, if necessary, remove from the female genitalia and in a urethane home-made cup attached to the shaft of the motor that reverses the rotation direction every 1/4 to 1/2 rotation Ejaculate by inserting their tips into the genitalia, pull out the male genitals, contact the opening with the female genitals, increase the air pressure in the middle layer, push the internal rubber film into the female genitals, send in the antistatic solution, pregnancy May be planned.

The surfaces of the inner layer and the outer layer of the container 1 must have affinity for the lubricating liquid and be very soft. A natural rubber thin film having a low degree of vulcanization satisfies the conditions, but if thickened, it becomes harder than the foreskin and mucous membrane on the surface of the genitals. In order to obtain a very flexible surface, the following may be performed. Polyester polyurethane with a diameter of 10 μm or less
Weave a velvet-like cloth with silk and other fine fibers, their surfaces coated with a very thin natural rubber, and as thin as possible the sprinkled rubber fibers. (When the loop on the surface is cut,
Sometimes it doesn't cut. In addition, depending on the velvet surface portion, the length of the bristle feet may be changed to form a concave protrusion. This is adhered to the rubber membrane surface, and the aqueous solution (sol) of glycoproteins such as alginic acid, sodium alginate, pectin, polyvinyl alcohol, liquor, gelatin, casein, mucin, and other substances, and yamaimo , An aqueous solution of fine powder of seaweed, silicone containing a volatile solvent, and a silicone rubber sol, etc., are filled, and the solvent is freeze-dried or naturally evaporated. In the case of using water as a solvent at the time of use, it is immersed in hot water for several minutes and returned to the sol or gel, and the oily solvent is used as it is. These are coated on the surface with a soft thick gel or sol. The softer,
It is easy to peel off, but velvety hair prevents shedding. After attaching the velvet to the rubber film, immerse it in an aqueous solution of calcium chloride, shake off the water by centrifugal force, etc., and dry it.A small amount of calcium chloride will adhere to the surface of each fiber. Water-soluble calcium alginate is attached to the surface of the fiber, and a water-soluble but flexible and viscous sodium alginate sol or gel may be attached to the outer layer.
(Thrombin, an enzyme that converts fibrinogen into water-insoluble fibrin instead of calcium chloride, is attached to the surface and immersed in an aqueous solution of fibrinogen collected from bovine blood containing calcium ions and other coagulation cofactors. A material having a membrane and a fibrinogen sol or gel attached to the outer surface may be made.) The composite of the velvet and the gel is rich in elasticity, and
If it is airtight, the rubber film attached to the lower surface may be omitted, and the container 1 having a cavity may be formed by itself.
One or several very thin rubber films on the velvet surface,
It may be adhered in a scattered manner to prevent peeling of the surface. In this case, the injection needle may be pierced into the velvet to inject the sol. After applying the sol as described above to the surface of the above fine fiber and drying it, knit a cloth or knit with a stuffed thread or a stuffed cocoon with a soft stuffed cotton thread and dried. It is made and filled with a sol, and is adhered to the inner and outer layers of the container part 1, and immersed in water at the time of use to make it soft. While not dried, it may be soaked in a sol containing the same preservative at a low concentration, stored in a bag, and removed from the bag at the time of use. Apply a liquid such as sulfur chloride to the surface of the inner and outer layers made of garbage, immerse it in a liquid of liquid, spray a latex liquid, and form a thicker rubber layer that is harder near the substrate and softer on the surface. Is also good. After applying rubber particles and latex containing starch particles to the rubber surface and reacting with sulfur chloride, dissolve the starch in warm water to make it into a starchy powder, and remove the formic acid in the micropores. May be impregnated. A high-concentration aqueous solution of fibrinogen taken from bovine blood or the like is applied to the surface of the inner and outer layers, immersed in a coagulation factor solution to form and adhere to a fibrin fiber sponge, and an aqueous solution containing fibrinogen in a lower concentration than before is used. Gradually, an open layer of fibrin sponge may be overlaid and their networks impregnated with mucin or other viscous sol. After adhering a polyurethane sponge having a thickness of about 1 mm to the surface of the rubber film for the inner and outer layers, the hydrophilicity may be increased by chemical treatment or the like, and mucin or the like may be impregnated. This urethane foam is impregnated with an aqueous solution of calcium chloride, centrifugally dehydrated, and then impregnated with a dilute aqueous solution of sodium alginate in the urethane foam layer, and is further applied to a height of about 1 mm from the surface thereof, and the surface is coated with an aqueous solution of calcium chloride. Most sodium alginate may be converted to a gel of insoluble calcium alginate. (In this case, the calcium alginate gel contains a lot of water, so it does not become so hard. Of course, mucin, sodium alginate and other sols may be further impregnated.) The protein or alginate sol was filled. In this case, a curing agent containing formalin or calcium ions may act only on the surface to reduce the water solubility of the surface. A seamless test tube knitted with very thin polyurethane or the like may be impregnated with rubber, gelatin, or the like and used as a material for the container portion 1.

Mucus as a physiological lubricating liquid is an aqueous solution containing mucin, a glycoprotein that strongly attracts water molecules, strongly adheres to the foreskin and mucosal surface, forms a slightly thick layer, maintains a suitable viscosity, In addition to the action, it also acts to protect the surface.
(If the viscosity is too small, the adhesion layer becomes thin, and if it is too large like a gel, an adhesive action appears, the lubrication / abrasion action becomes small, and the texture is impaired. Therefore, a sol having a viscosity that is not so large is preferred.) If the surface of the container is hydrophilic, mucin solution or the like may be used, but rubber and many plastics are hydrophobic, and the adhesion of the aqueous lubricating liquid is not very good. The rubber may be made hydrophilic by adding polyvinyl alcohol, alginic acid, or the like, or the surface may be covered with a hydrophilic substance.However, if the film surface is lipophilic, an oily substance or a sol of water and oil can be used. A lubricating liquid may be used. In addition, as described above, the tactile and vibrational receptors are deformed, and since it is important that the deformation moves, in an aqueous or oily liquid component,
Structure or soft plastic spheres, starch particles, lumpy spheres of about 0.01 to 0.1 mm close to the size of the receptor,
It is desirable to use a lubricating liquid containing microcapsules or the like in which the liquid is sealed. A large number of easily deformable particles in which a liquid such as water is sealed in a thin rubber sphere having a diameter of about 1 cm may be added to the lubricating liquid. If the material is soft such as rubber, the shape of the grains may be cubic, irregular, or other. Such a lubricating liquid containing particles may be put in a small tube or the like and applied to the container 1 at the time of use. To make microcapsules, an aqueous solution of sodium alginate is dropped into an aqueous solution of calcium chloride to solidify the surface, or sulfur chloride is applied to the surface of the particles, dropped into a rubber latex solution, and a vulcanized rubber layer is formed on the surface. Alternatively, a rubber latex solution may be dropped into sulfur chloride.
