DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a rubber packing for a negative pressure suction device according to a first embodiment of the present invention and a method of using the same will be described below with reference to FIGS.

Referring to FIGS. 1 and 2, the rubber packing for the negative pressure suction device according to the present embodiment has a thin cylindrical shape having an outer diameter of about 40 mm, a thickness of about 0.8 mm, and a length of about 8 mm in the central axis direction. A large-diameter portion 1, an annular portion 2 having a thickness in the radial direction of about 2 mm and a length of about 3 mm in the central axis direction provided around the entire rear end of the large-diameter portion 1, and a front end of the annular portion 2. Small diameter part 3 extending forward
And The small diameter portion 3 has a thickness of about 1 mm, a length in the central axis direction of about 19 mm, and an inner diameter of all ends of about 14 mm, and has a diameter from the rear end to the front end as shown in FIG. It has a thin, generally cylindrical shape that decreases.

When using the rubber packing of the present embodiment, as shown in FIG. 4, the central axis of the small diameter portion 3 is positioned at the center of the open end of the cylindrical main body 4 of the negative pressure suction device. The large-diameter portion 1 is folded back so that the entire surface of the large-diameter portion 1 is brought into close contact with the outer periphery of the cylindrical body 4 near the open end.

Next, the male genitalia is inserted into the cylindrical main body 4 through the insertion hole 5 over its entire length. In this state, the surface of the small diameter portion 3 of the rubber packing closely adheres to the periphery of the base of the male organ,
The internal space of the tubular main body 4 is sealed. Then, pump 6
To make the internal space of the cylindrical main body 4 decompressed,
Helps erection by making it easier for blood to flow into the cavernous body of the male organ.

When the desired erection state is obtained, the cylindrical body 4
By pulling out the rubber packing, the rubber packing remains on the base of the male genital in a state where its periphery is tightened by the elastic force of the rubber. This prevents blood collected in the corpus cavernosum from flowing back to the human body, and maintains an erected state.

The above operation is the same as that of the conventional rubber packing for a negative pressure suction device. The rubber packing for negative pressure suction of this embodiment is different from the above-mentioned conventional one in the following points.

First, a groove 7 having a V-shaped cross section is provided on the inner surface of the small-diameter portion 3 of the rubber packing from the rear end to the front end of the small-diameter portion 3 in a substantially central axis direction. This groove 7 is intended to be easily broken after using the rubber packing so as not to cause pain when removing the rubber packing, but it is necessary to maintain at least enough strength not to be broken in a use state. No. In this embodiment, the depth of the groove 7 is set to 0.4 mm. The groove 7 having such a shape can be formed at the same time when the rubber packing of the present embodiment is integrally formed from a sheet-like rubber material by a mold. The groove 7 is formed on the inner surface of the annular portion 2, the large diameter portion 1, and the small diameter portion 3 from the rear end of the annular portion 2 to the front end of the small diameter portion 3.

On the front side surface of the small diameter portion 3 corresponding to the position where the groove 7 extends, a pair of ridges 8 and
8 are provided. Further, a heart-shaped knob 9 is formed at a position where the groove 7 is provided on the outer periphery of the annular portion 2 at a position sandwiching the end of the groove 7 from both right and left sides. Knob 9
Has the same thickness as the annular portion 2, but has a pair of annular projections 9 a, 9 a for preventing slippage on its surface, and a position sandwiched between the pair of projections 9 a, 9 a. Is provided with a thin-walled tapered portion 9b having a tapered cross section.

During use, the rubber packing remaining at the base of the male genital in the state shown in FIG.
By pinching the pair of projections 9a, 9a of the knob 9 with the fingers of both hands and pulling it to the left and right, the thin tapered portion 9 of the knob 9 is formed.
A break occurs from b. Thereafter, the tearing proceeds along the groove 7 and can be easily broken over the entire length of the rubber packing. As a result, it is possible to easily remove the rubber packing without causing a phenomenon that the front end of the small diameter portion 3 is hardly stuck and detached as in the conventional product, causing a pain.

The pair of ridges 8, 8 provided on the surface of the small-diameter portion 3, even when the breach breaks out of the groove 7, proceeds in the circumferential direction of the small-diameter portion 3 so that the breach advances. In order to prevent the problem that only the portion near the front end of 3 remains, the thickness is provided to increase the thickness of the small diameter portion 3 at the position sandwiching the groove 7 from both sides.

The pair of ridges 8, 8 are not formed on the surface of the large diameter portion 1. That is, when a convex ridge is formed on the surface of the large-diameter portion 1, the surface of the large-diameter portion 1 and the surface near the open end of the cylindrical main body 4 in the state of being attached to the cylindrical main body 4 shown in FIG. This is because a gap is generated between the two and air leaks when the pump 6 is operated, so that a desired reduced pressure state cannot be obtained. Since the thickness of the large diameter portion 1 is smaller than the thickness of the small diameter portion 3 and the depth of the groove 7 is constant, the thickness of the groove 7 at the valley bottom is smaller than that of the small diameter portion 3 in the large diameter portion 2. ing. Therefore, in the large-diameter portion 1, the tearing proceeds reliably along the groove 7, and there is no need to provide a guard such as a pair of ridges 8,8. In addition, since the large-diameter portion 1 does not require strength as the small-diameter portion 3 does, there is no particular problem even if it is so thin.

The rubber packing having the structure of the present embodiment can integrally mold a sheet-like rubber material with a mold, and has good productivity.

In this embodiment, the groove 7 is formed on the inner peripheral surface of the rubber packing. However, the groove 7 is formed on the outer peripheral surface, that is, on the surface of the small-diameter portion 3 in a region sandwiched between the pair of ridges 8,8. However, substantially the same operation and effect can be obtained.

The knob 9 is not limited to the shape of this embodiment as long as it can be pinched by both fingers and pulled to the left and right sides. The pair of annular projections 9a, 9a serving as anti-skids is not limited to an annular shape, but may have other shapes as long as irregularities for anti-slip are obtained. When the rubber packing of this embodiment is broken after use, it is in the state shown in FIG. 5 and is discarded. The above-mentioned conventional rubber packing for a negative pressure suction device has been repeatedly used many times in order to keep its original shape even after use, but it was not preferable from a sanitary viewpoint. On the other hand, the rubber packing of the present embodiment is extremely sanitary because it is disposable one by one.

Next, a second embodiment of the present invention will be described with reference to FIG. In the rubber packing for a negative pressure suction device of the present embodiment, instead of the groove 7 in the first embodiment, a V-shaped groove 17 having a predetermined length is intermittently formed at predetermined intervals. Only this point is different from the first embodiment. According to the present embodiment, since there is a portion where no groove is formed between the adjacent grooves 17, the small diameter portion 3 is formed.
The structure in which the strength of the region where the groove is formed is maintained higher and the tearing can be sufficiently advanced is realized.
The strength of the small diameter portion 3 is an important characteristic required to obtain a sufficient tightening force as a rubber packing for preventing backflow of blood and to prevent tearing in use.

Next, a third embodiment of the present invention will be described with reference to FIG. The rubber packing for the negative pressure suction device according to the present embodiment includes a surface of the small diameter portion 3 in a region between the pair of ridges 8, 8 instead of the V-shaped groove 7 in the first embodiment. A cut groove (so-called half cut) 27 having a depth of about 0.4 mm is formed on the surface of the large diameter portion 1. Such a cut groove 27 can be formed by making a cut with a knife edge in the rubber packing after being integrally molded. Such a kerf 27
By providing the same, as in the case of the first embodiment, it is possible to cause the breach generated from the knob 9 to proceed along the incision 27 and to easily remove it after use. Become. In the present embodiment, the cut groove 27 is formed on the front surface of the rubber packing. However, it may be formed on the inner surface, that is, at the same position as the groove 7 in the first embodiment.

Next, a fourth embodiment of the present invention will be described with reference to FIG. The rubber packing of this embodiment is
Instead of the kerf 27 in the third embodiment, the groove 3
7 is formed at a predetermined pitch intermittently in a perforated shape.

According to this embodiment, since there is a portion where no groove is formed between the adjacent grooves 37, the strength of the small diameter portion 3 during use can be maintained high as in the second embodiment. it can.

[0045]

As described above, according to the present invention, the rubber packing can be easily removed without pain by breaking the rubber packing along the groove after use. Disposable. Therefore, it is possible to easily and safely use a negative pressure suction type erection assisting device having characteristics superior to other treatment methods such as no side effect. In addition, hygiene is improved as compared with a conventional product used repeatedly.

As a result, it is possible to eliminate the worries of men who have erectile dysfunction, and to help them regain a worthwhile life. Furthermore, since it is applied to relatively elderly men, it has a unique effect that it plays an important role as a measure against transition to an aging society.
