DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a tightening member used in a device for causing an erection of a male genital organ by utilizing a reduced-pressure suction action.

[0002]

2. Description of the Related Art For male genitalia that cannot exhibit an erection due to psychological or physical reasons, an erection assisting device utilizing reduced pressure is used as a device that also serves as a treatment. This device places the male genitals partially or wholly in a decompressed environment, forcing blood into blood vessels in the corpus cavernosum tissue, and venous flow to the roots of the male genitals, which expand and solidify due to vasodilation. The erection state is maintained for a predetermined time by attaching a tightening member for preventing the reflux of the erection. As a means for keeping the male genitals under a reduced-pressure suction environment, a cylindrical member having one end open to insert the male genitals and the other end connected to a conduit communicating with the suction pump is used. The cylinder into which the male genitals are inserted is pressed so that the open end is in close contact with the skin around the base of the genitals,
The internal pressure is reduced by the operation of the suction pump.

[0003] The fastening member is disclosed, for example, in US Pat.
As shown in JP-A-8,008, JP-A-4,741,329 or JP-A-1-212552, it is composed of a ring-shaped simple band or compression body made of a rubber material. Generally, these tightening rings are attached to the outer periphery of the open end of the above-mentioned cylinder before the male genitals erect, and after the erection, they are removed by hand or the like around the base of the male genitals when the cylinder is removed from the male genitals. It is.

[0004]

However, in the case of the conventional tightening ring, when the cylinder is transferred from the outer periphery of the open end to the male genitalia, the rubber material strongly collides with the genitals due to the strong elasticity of the rubber material inward in the radial direction. Because of that, the feeling of pain is remarkable. In addition, a large expansion force is required for mounting to the open end of the cylinder, and the usability when mounting the genitals is poor. Furthermore,
After use, if no lubricant is used, slippage is poor and removal is troublesome. An object of the present invention is to provide a tightening member of this kind which does not cause a great pain at the time of mounting, has good usability, and does not require a lubricating material for removal in view of the problems of the conventional tightening ring. Is to provide.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, a feature of the present invention is to reduce blood pressure in a cylinder into which a male genital is inserted, thereby causing blood to flow into blood vessels in the cavernous tissue of the male genital. Forcibly attracting and tightening a part of the male genital erected by the expanded blood vessel to prevent the return of the blood and maintain an erected state, a tightening member used for an erection assisting device of the male genital , Male genitals
Resiliently and detachably attached to the outer periphery of the open end on the insertion side
A clamping member, the clamping member body is formed by a synthetic resin elastic gel material, of the clamping member body in the middle portion, of diameter with sufficient elastic recoil to prevent reflux of the blood when expanded The point is that a through hole is formed.
As the male gel material, a polyethylene gel material is desirable.

[0006]

With this fastening member, the through hole is expanded with fingers or the like,
It is mounted on the outer periphery of the open end of the cylinder in the same manner as a conventional tightening band. And since this fastening member has moderate viscoelasticity and is in the form of jelly, even when it is transferred from the outer periphery of the open end to the root of the male genitalia, the contact is soft and the pain is alleviated. In addition, the feeling of being attached to the genitals does not have a heterogeneous feeling like a rubber material, and does not cause discomfort to a partner at the time of sexual intercourse. Furthermore, since the present fastening member has such a smoothness as to be appropriately wet, it is not necessary to apply a lubricant such as jelly when removing after use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on illustrated embodiments. FIG. 1 is an overall external perspective view of an erection assisting device using a fastening member according to one embodiment of the present invention. In the figure, reference numeral 1 denotes a cylinder having a deaeration port 3 in a bottom wall 2 whose inside is decompressed with a male genital inserted. The other end of the tube 5 having one end connected to the suction port of a pump (not shown) of the deaerator 4 is connected to the deaeration port 3.

Reference numeral 6 denotes an open end of the cylinder 1, which has a double wall structure in which an outer wall 6b surrounds the outer periphery of the inner wall 6 at a required interval as can be seen in detail in FIGS. The lower end of 6b is connected to the inner wall 6a by a flange-like horizontal wall 6c.

Reference numeral 9 in the figure denotes a shallow groove formed on the outer periphery of the outer wall of the open end 6 of the cylinder 1. A tightening ring 10 is mounted in the groove 9 by utilizing its elasticity. The fastening ring 10 is formed of an elastic gel material made of synthetic resin. As a specific material, for example, polyethylene-based elastic gel manufactured by Ohba Kiko Co., Ltd. is suitable. Various types can be selected for tensile strength and elongation. For example, in this example, this elastic gel is used under the test conditions of JIS K6301 under the following test conditions:
Tensile strength is 7.9kg / cm2, elongation is 1300-1
500%, rebound resilience 25%, and compression set 1
2% and a hardness Hs of 4 under the test condition SRIS0101 were used. This elastic gel has moderate viscosity and elasticity. In addition, an elastic gel having a required elasticity, such as one obtained by wrapping silicone with a polyethylene gel material, can be used as the fastening member. The tightening ring 10 made of an elastic gel material may have a narrow width as shown in FIGS. 1 to 3, but as shown in FIG. 4, a disk-shaped main body 10a having a rounded outer peripheral surface and a required thickness May have a small-diameter through hole 10b formed at the center. This through hole 10b
Is formed into a system that has sufficient elastic contractile force to prevent blood return when dilated with a diameter smaller than that of a male genitalia in an erect state. Then, by pulling the through-hole 10b with a finger or the like, a ring having an appropriate elastic contraction force toward the center is obtained as shown in FIG.

Reference numeral 7 denotes a groove between the inner wall 6a and the outer wall 6b. The groove 7 has a packing member 8 having substantially the same shape as the groove 7.
Are inserted and fixed so that the front end surface 8a thereof slightly protrudes from the upper end surfaces of the inner and outer walls 6a and 6b (see FIG. 3).

A suction pump driven by an electric motor is provided in the deaerator 4, and a gauge 4a for indicating the pressure in the cylinder and a switch for turning on / off the electric motor are provided on the casing surface. 4b (see FIG. 1). In addition, the deaerator 14
Although not shown, a vertical type having an inclined surface on one side end of the upper surface may be used, and a foot-operated type in which the pressure indicating gauge and the switch are arranged on the inclined surface may be used. Further, the degassing device 4 and the cylinder 1 may be directly connected to the degassing port 3 of the cylinder bottom 2 and the tube connection port of the degassing device 4 detachably without the tube 5 interposed therebetween. When the cylinder and the deaerator are directly connected, the switch is naturally operated by finger.

The erection assisting device having the above configuration is used in the same manner as a conventional product. When the user inserts the elastic genitalia M into the cylinder 1 and presses the open end 6 of the cylinder 1 against a body part around the base of the genitalia, the end surface of the cylinder open end 6, that is, the end surfaces of the inner and outer walls 6a and 6b. Since the tip end surface 8a of the packing member 8 protrudes outward more than this, this portion comes into contact with the body part and is elastically deformed. Since the packing member 8 is made of an elastic gel material and has a jelly-like shape, the surface of the body can be finely deformed even by irregular irregularities or pubic hair of the body, and the body can be subjected to only a slight pressing force. (See FIG. 6). Therefore, when the suction pump of the deaerator 4 is operated, the pressure inside the cylinder is rapidly and efficiently reduced. Thereafter, the cylinder 1 may be slightly lifted, and at the same time, the clamping member 10 may be transferred to the base of the genitals by manually shifting the fastening member 10 from the concave groove 9 on the outer periphery of the open end. At this time, since the fastening member 10 is made of an elastic gel material, a strong elastic collision does not occur at the base of the genitals at the time of this transfer, and the user can work with peace of mind. Further, the fastening member 10 attached to the genitals
Has an appropriate viscoelasticity and does not cause any discomfort.

FIGS. 7 and 8 show a modification of the cylinder. The cylinder 11 has a gentle slope formed on the outer periphery of the cylinder body reaching the open end portion 16.
According to this, when the fastening member 10 is mounted on the outer periphery of the open end portion 16, the inner diameter of the fastening member 10 can be expanded by gradually moving it from the cylinder bottom wall 12 side. Despite being thicker than the cylinder body 1a, the operation can be performed easily. Also,
The cylinder 11 is evacuated to the bottom wall 12 and a safety valve B for manual operation is attached to the cylinder 13. The safety valve B is made of rubber, and when the cylinder 11 is depressurized, the flange portion b is in close contact with the outer surface of the bottom wall 12 to maintain airtightness in the cylinder, while being bent by a finger as needed. The inside of the cylinder is returned to normal pressure by releasing the close contact state of the flange portion b (see the sectional view of FIG. 7).

A packing member 18 attached to the open end 16 of the cylinder 11 has two ring-shaped peaks 18a and 18 on its protruding tip surface as shown in FIG.
b is formed. The outer portions 18a of the two mountain portions 18a, 18b protrude longer than the inner portions 18b.
Therefore, according to the packing member 18, one of the two peaks 18a and 18b having different heights is brought into contact according to the unevenness of the body part, so that the airtightness inside the cylinder 11 can be further improved. In addition, the pressing force at the time of use can be further reduced.

In the above embodiment, the outer shape of the tightening member is circular, but the present invention is not limited to this, and various shapes can be used.

[0016]

As described above, according to the present invention, since the fastening member is formed of an elastic gel material made of synthetic resin, the jelly-shaped viscoelasticity allows the deaeration syringe to be formed.
The contact at the time of transfer collision from the outer periphery of the opening end to the male genitalia can be softened, and the tightening at the time of use can be performed softly and without any foreign feeling. Furthermore, according to the present invention, the material can be easily removed without using a lubricant due to the wetness of the material.
