Description

The present invention relates to a soft resin breast pad used by being sandwiched (held) between the chest and the breast by a brassiere.

A breast pad that is stored in a cup of a brassiere and used to supplement a resected breast as a treatment for breast cancer or the like and to supplement a bulge of the chest has been widely used.

This type of breast pad is used by being held between the chest and the brassiere, not fixed to the chest or brassiere, and therefore moves within the brassiere and is misaligned. In some cases, the fit was not always good.

Therefore, conventionally, a breast pad that can reduce a feeling of discomfort when worn has been proposed. For example, Patent Document 1 discloses a breast pad made of cloth and provided with wings protruding downward from the lower periphery of the pad body to reduce the displacement of the pad body.

Japanese Unexamined Patent Publication No. 2016-79545

However, the cloth breast pad as disclosed in Patent Document 1 lacks the texture and weight of the actual breast. On the other hand, the breast pad made of soft resin such as silicone (rubber) is superior in texture and weight to the breast pad made of cloth. In addition, when trying to eliminate the displacement of the pad body by providing wings that protrude downward from the lower periphery of the pad body of the breast pad, the breast pad made of soft resin is relatively heavier than the one made of cloth. Elimination of breast pad misalignment is inadequate.

Further, the displacement of the breast pad is likely to occur due to the movement of the wearer, and may be displaced not only by the displacement in the vertical and horizontal directions but also by the rotation in the cup of the brassiere. For example, in the case of a breast pad made of soft resin, which is deformed into a circular shape in a plan view to make it closer to the actual shape of the breast, the breast pad rotates in the cup of the brassiere, so that the appearance shape of the breast is worn in the correct posture. It may be deformed.

On the other hand, as a model breast for breast cancer palpation, a soft resin breast pad is known in which a model affected part imitating the elasticity of breast cancer tissue is embedded inside and the surface has a convex curved surface imitating the shape of the breast. There is. This breast pad lacked usability because the entire breast pad moved during palpation.

Therefore, the applicant first obtains a pad body having a convex curved surface whose surface imitates the shape of a breast, and a breast pad having a thin flange portion extending outward from the lower portion of the peripheral edge of the pad body to the side. developed. This breast pad is intended to reduce the displacement of the pad body housed in the cup by pressing the flange portion with the lower end edge of the peripheral edge of the cup of the brassiere.

However, those who have had their breasts resected due to breast cancer or the like tend to wear loose bras with a sufficient size because they do not want to tighten the wound too much. Then, the pressure on the flange portion becomes weak, and when the pad body moves up and down due to movement or the like, the pad body may pop out from the upper side of the brassiere or a feeling of popping out occurs. In addition, they do not have a sense of security about exercise and will instill a sense of refraining from strong exercise.

The present invention has been made in view of the above-mentioned problems, and gives a sense of security against misalignment during use even when a loose brassiere is used or when a strong exercise is performed. It is an object of the present invention to provide a breast pad made of a soft resin such as silicone (rubber) that can be produced. Another object of the present invention is to provide a breast pad as a model breast for breast cancer palpation, which is excellent in usability.

As a result of intensive research to achieve the above object, the present inventor has provided a thin flange (feather) extending outward from the lower part of the peripheral edge of the pad body to the side of the breast pad made of soft resin, and further. When the convex stopper is arranged along the outer peripheral edge of the flange portion, the lower end edge of the cup of the brassiere fits between the outer peripheral edge of the pad body and the convex stopper, and the breast pad is stable and the brassiere. It was found that it can be stored in the cup and the breast pad can be further reduced from rampaging in the cup, especially from the upper side.

That is, the breast pad according to one aspect of the present invention is a breast pad made of soft resin that can be used by holding it on the chest without being fixed to the brassiere by wearing a brassiere, and the surface of the breast pad imitates the shape of the breast. The pad body has a convex curved surface, a thin flange portion extending outward from the lower portion of the peripheral edge of the pad body to the side portion, and the same as the convex direction of the convex curved surface of the pad body continuously from the surface of the flange portion. It is characterized by having a convex stopper that protrudes to the side and is provided at a predetermined distance from the peripheral edge of the pad body.

In the breast pad, a known soft resin can be widely used, and it is preferable to use a known soft resin generally used as a material for artificial breasts. Further, since this breast pad is used in contact with the chest, it is particularly preferable to use a medical soft resin such as silicone (rubber).

Further, the extending length (protruding width) of the flange portion of the breast pad is more than enough to be pressed by the cup peripheral edge (lower part and side portion) of the wearing brassiere, and if it is too long, a feeling of discomfort in wearing does not occur more than necessary. It is preferable to set the degree. The extending length of the flange portion depends on the size of the pad body, but may be, for example, about 10 to 30 mm. Also, if there is a difference between the cup size of the brassiere and the size of the pad body, that is, even if the size of the pad body is small, the side when the pad body is displaced in the left-right direction in the cup of the brassiere. The protruding width may be set so that the flange portion of the portion does not enter the cup.

Further, the thickness of the flange portion of the breast pad should be as thin as possible within a range that guarantees the strength to withstand use. On the other hand, it suffices if it is thick enough to be pressed by the periphery of the cup of the brassiere when attached. The thickness of the flange portion may be, for example, about 0.2 to 1.5 mm when it is made of silicone rubber. Further, the thickness of the flange portion may be uniform or non-uniform. For example, the fit may be improved by adding a taper so that the tip becomes thinner.

Further, a plurality of convex stoppers are arranged side by side on the flange portion so as to be spaced apart along the outer peripheral edge of the flange portion, but when three or more are provided, the separation distance is uneven even if it is uniform. You may. The convex stopper is arranged on the flange portion along the peripheral edge of the flange portion, so that the convex stopper is formed at a position separated from the edge of the pad body. The length (separation distance) between the edge of the pad body and the convex stopper may be appropriately determined depending on the design (shape), size, etc. of the brassiere to be used, and may be, for example, about 10 to 25 mm. .. The shape of the convex stopper is not particularly limited, such as a rectangular shape, a circular shape, or a rectangular shape having a curvature when viewed from above, and may be a shape in which the upper portion expands from the lower portion or vice versa. The size is not particularly limited, and may be an appropriate size. For example, the length can be about 10 to 20 mm, the width can be about 5 to 10 mm, and the height can be about 5 to 10 mm. The number of convex stoppers may be appropriately determined, preferably 3 to 6. Further, the plurality of convex stoppers are preferably arranged as a whole from the lower part of the peripheral edge of the pad body to the side portion, and are arranged below the center line of the pad body.

According to the above breast pad, when worn (when used), the lower end of the pad body and at least one or more convex stoppers on the flange are pressed against the chest by the cup peripheral portion of the brassiere. .. As a result, the breast pad in the cup of the brassiere is resistant to vertical sway caused by walking or running when worn, and horizontal swaying when the arm is moved or the body is twisted. It is possible to effectively reduce the deviation in the vertical and horizontal directions and the deviation due to rotation. Even if you are using a brassiere of a generous size or if you exercise hard, you can reduce the amount of the breast pad popping out from the top of the brassiere, and you can use it with confidence.

Further, in the breast pad, it is preferable that the flange portion is provided on the side portion of the pad body on the arm portion side (side portion side). Further, in the breast pad, it is more preferable that the flange portion is provided so as to extend over both side portions of the peripheral edge of the pad body. As a result, the pad body can be more effectively absorbed and attenuated by pressing and correcting the pad body in the vicinity of the arm where the movement is large. Further, the convex stoppers can be arranged up to both sides, and the allowable size of the brassiere can be increased.

Further, in the breast pad of the present invention, it is preferable that a plurality of convex stoppers are arranged side by side on the flange portion so as to be separated from each other, and the flange portion is not formed on the upper side of the peripheral edge of the pad body. In other words, although it depends on the size of the flange part, the flange part protrudes onto the cup of the brassiere, and when a shirt or blouse is worn on the jacket, the flange part is visible from the open collar part (chest part). This is because it may impair the cohesiveness.

Further, in the breast pad of the present invention, the pad body may be a hollow bag-like body, and the flange portion may extend from the bottom surface thereof. As a result, the weight of the breast pad can be reduced, and the deviation of the mounting position can be further reduced.

Further, the thickness of the upper layer of the pad body formed of the hollow bag-like body is made thicker than the thickness of the lower layer, a recess is formed in the central portion of the lower layer, and an injection needle for air injection is inserted into the recess. A valve may be formed. By doing so, the air pressure of the pad body can be adjusted as appropriate according to the size of the user's chest, and by thickening the upper layer of the pad body, the air injection needle is pierced from the thinner lower layer. It is possible to reduce the accidental penetration of the upper layer. The thickness of the upper layer of the pad body can be made thick enough so that the weight of the breast pad does not become heavier than necessary. For example, when silicone (rubber) is used for the soft resin, it depends on the size of the pad body. It is preferably about 5 to 10 mm. The thickness of the lower layer of the pad body is preferably about 1 to 5 mm.

Here, as the needle insertion valve in the breast pad, for example, a rubber material similar to that called "heso" or "mushi" provided for injecting air into a tennis ball, volleyball, or the like. Needle insertion valves and needle insertion valves made of medical and industrial materials can be widely used. The needle insertion valve may be the same member as the soft resin forming the lower layer (bottom surface) or a different member, but is made of a well-known rubber material called "navel" or "mushi". Is more preferable as a separate member and integrated so as to be embedded in the soft resin of the lower layer (recess).

According to such a breast pad, since the needle insertion valve is formed in the recess of the lower layer (bottom surface) of the pad body, it is possible to reduce the contact of the needle insertion valve with the skin of the chest at the time of wearing, and the needle insertion valve can be reduced. When another member such as the above-mentioned "navel" is used, the safety can be improved and the air permeability can be improved. Further, the pad size of the breast pad can be adjusted by adjusting the air pressure using a general-purpose small pump with the needle insertion valve. Further, by making the thickness of the lower layer of the pad body relatively thin and providing a recess in the lower layer (bottom surface), the elasticity of the lower layer can be improved, and the wearing feeling (usability) can be further improved. .. Further, it is possible to prevent the flange portion from being pulled or loosened and displaced due to the change in the air pressure of the pad body, and it is possible to easily maintain a constant pressing feeling by the brassiere.

Further, the breast pad according to another aspect of the present invention is a breast pad made of soft resin used as a model for breast cancer palpation, in which a model affected part imitating the elasticity of breast cancer tissue is embedded and the surface is surfaced. A pad body having a convex curved surface that imitates the shape of a breast, a thin flange portion extending outward from the lower end of the peripheral edge of the pad body, and a parallel arrangement on the flange portion along the outer peripheral edge of the flange portion. It is characterized by having a plurality of convex stoppers.

The flange portion of the breast pad may be formed so as to extend from one peripheral edge to the entire peripheral edge of the lower end of the peripheral edge of the pad body, and it is more preferable to extend the flange portion from the entire peripheral edge. Further, the extending length of the flange portion is preferably long because the stability is improved, and may be, for example, about 10 to 40 mm.

According to this breast pad, by having the flange portion, it is possible to produce a feeling of use closer to the actual chest.

According to the present invention, it is possible to provide a breast pad made of a soft resin such as silicone (rubber), which reduces wearing deviation during use. Further, according to the present invention, it is possible to provide a breast pad as a model for breast cancer palpation, which is excellent in stability and highly practical.

It is a schematic front view which shows an example of the breast pad which concerns on embodiment of this invention. FIG. 1 is a schematic cross-sectional view taken along the line II of FIG.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic front view showing an example of a breast pad according to an embodiment of the present invention. The breast pad 1 is a bowl-shaped (convex curved surface) pad body 2 that imitates a breast, a flange portion 3 extending downward from the lower edge of the peripheral edge of the pad body 2 in a flange shape, and a flange portion 3 above. , It has four convex stoppers 4, 4, 4, 4 arranged side by side along its outer peripheral edge. The breast pad 1 is formed by using medical silicone (rubber).

As shown in FIG. 2 with a schematic cross-sectional view of the breast pad 1, the pad body 2 has an upper layer 2a forming a convex curved surface shape and a lower layer 2b forming the bottom of the upper layer 2a, and the convex space of the upper layer 2a. The inner space is formed by covering the lower layer 2b with a lid, and the whole is a hollow bag-like body. An upward recess 2b1 is formed in the central portion of the lower layer 2b. A needle insertion valve 2b2 is formed in the central portion of the recess 2b1 so that the air pressure in the internal space can be adjusted by moving air in and out of the internal space. The needle insertion valve 2b2 is formed of a general-purpose needle insertion valve used in tennis balls, volleyball, and the like.

The thickness of the upper layer 2a is not particularly limited, and in this example, it is about 5 to 10 mm. The thickness of the lower layer 2b is not particularly limited, and is thinner than that of the upper layer 2a, and in this example, it is about 1 to 2 mm.

The flange portion 3 is formed in the form of a thin sheet extending outward from the lower end of the peripheral edge from the lower portion 2a1 of the pad body 2 to the side portion (side side when mounted) 2a2 and the opposite side portion 2a3. The thickness of the flange portion 3 is not particularly limited, and in this example, it is about 0.5 to 1 mm.

The convex stopper 4 is formed on the flange portion 3 separated from the outer peripheral lower end edge (lower portion 2a1, side portions 2a2, 2a3) of the pad body 2 by a predetermined distance. Here, the convex stopper 4 is arranged on the outer peripheral edge side of the flange portion 3, but the flange portion 3 may extend further outward from the formation position of the convex stopper 4.

In the present embodiment, four convex stoppers 4 are provided so as to be separated from each other along the outer peripheral edge of the flange portion 3, but three or five or more convex stoppers 4 may be provided. The distance between 4 and 4 is not particularly limited, but is preferably about 20 to 40 mm, for example. Further, the shape of the convex stopper 4 is not particularly limited, and if the height is higher than the height that can be locked to the lower part of the cup of the brassiere to be used, a columnar shape, a prismatic shape, a triangular pillar shape, an arc shape, a star shape, or the like. It can be shaped like a heart or the like. Here, it has a rectangular columnar shape having a length of about 10 to 15 mm, a width of about 3 to 5 mm, and a height of about 5 to 8 mm.

The breast pad 1 is formed by, for example, overcoating a medical liquid silicone on a plaster mold or pouring the liquid silicone into a plaster mold to cure the upper layer 2a and the lower layer 2b, a flange portion 3, and a convex stopper. 4 can be formed and these can be integrally manufactured by laminating them with an appropriate adhesive.

In addition, a convex portion having a shape imitating a nipple may be formed on the surface of the upper layer 2a of the pad body 2, so that the shape can be closer to the actual breast shape. Further, the breast pad 1 may be colored in any color.

The needle insertion valve 2b2 can be provided by being embedded in the recess 2b1 of the lower layer 2b of the pad body 2 before the silicone resin is cured, and is embedded by curing the silicone resin. By setting the needle insertion valve 2b2 to a color different from the color of the lower layer 2b (recess 2b1), its position can be easily understood and it is possible to prevent the needle for air injection from being pierced at the wrong position.

Further, in the breast pad as a model for breast cancer palpation according to the embodiment of the present invention, it is preferable that the internal space of the pad body 2 is filled with silicone resin or gel in the above-mentioned breast pad 1. .. Further, it is preferable that the flange portion 3 is formed over the entire periphery of the pad body 2.
