Description

  The present invention relates to a soft resin breast pad that is used while being held (held) between a chest by a brassiere.

  Breast pads that are housed in brassiere cups have been widely used to make up for breasts that have been excised as a treatment for breast cancer and the like, and to make up for breast swelling.

  This type of breast pad is used while being held between the chest and the bra, and is not fixed to the chest or the bra, and therefore moves and moves in the brassiere. In some cases, the feeling of wearing was not necessarily good.

  Therefore, breast pads that can reduce the uncomfortable feeling at the time of wearing have been proposed. For example, Patent Document 1 discloses a breast pad made of cloth and provided with wings that project downward from the lower peripheral edge of the pad body to reduce the displacement of the pad body.

Japanese Patent Laid-Open No. 2006-79545

  However, the cloth breast pad as disclosed in Patent Document 1 is poor in actual breast texture and weight. In contrast, a breast pad made of a soft resin such as silicone (rubber) is superior in texture and weight to a breast pad made of cloth. In addition, when trying to eliminate the displacement of the pad body by providing wings that project downward from the lower peripheral edge of the pad body of the breast pad, the soft resin breast pad is relatively heavy relative to the cloth, It can be said that the breast pad displacement is insufficiently resolved.

  Also, this breast pad displacement is likely to occur due to the movement of the wearer, and may be displaced not only by vertical and horizontal displacement but also by rotating within the brassiere cup. For example, in the case of a soft resin breast pad that has a circular shape deformed in plan view in order to approximate the shape of the actual breast, the breast pad rotates in the brassiere cup, so that the mounting appearance shape in the correct posture can be reduced. There is a risk of deformation.

  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 simulating the elasticity of breast cancer tissue is embedded inside, and the surface has a convex curved surface simulating the shape of a breast. Yes. This breast pad lacked a feeling of use because the whole breast pad moved during palpation.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a breast pad made of a soft resin such as silicone (rubber) with reduced mounting displacement during use. Another object of the present invention is to provide a breast pad as a model breast for palpation of breast cancer which is excellent in usability.

  The present inventor has conducted intensive research to achieve the above object, and in a soft resin breast pad, when a flange (wing) is provided also on the peripheral side of the pad body, not only in the vertical direction but also in the horizontal direction. It was found that the deviation of the rotation and the deviation of the rotation can be effectively reduced.

  That is, a breast pad according to an aspect of the present invention is a soft resin breast pad that is used while being housed in a brassiere cup, and a pad body having a convex curved surface whose surface imitates the shape of a breast, and the pad body It has the thin flange part extended outside from the lower part of a peripheral edge to a side part, It is characterized by the above-mentioned.

  In addition, in the said breast pad, a well-known thing can be widely used as a soft resin, It is preferable to use the well-known soft resin generally used as a material of an artificial breast. Moreover, since this breast pad is used in contact with the chest, it is particularly preferable to use a soft medical resin such as silicone (rubber).

  In addition, the extension length (protrusion width) of the flange portion in the breast pad is more than can be pressed by the cup peripheral edge (lower and side portions) of the mounting brassiere. It is preferable to set the degree. Although the extension length of this flange part is based on the size of a pad main body, what is necessary is just to be about 10-20 mm, for example. Also, if there is a difference between the brassiere cup size and the pad body size, that is, even if the pad body size is small, if the pad body is displaced in the left-right direction within the brassiere cup, What is necessary is just to set it as the protrusion width more than the grade which the flange part of a part does not enter in a cup.

  Further, the thickness of the flange portion of the breast pad is preferably thin as long as the strength enough to withstand use is guaranteed. On the other hand, it is only necessary to have a thickness that can be pressed at the cup periphery of the brassiere when worn. For example, when the flange portion is made of silicone rubber, the thickness may be about 0.2 to 1.5 mm. Further, the thickness of the flange portion may be uniform or non-uniform. For example, the fit may be enhanced by providing a taper so that the tip is thinner. Further, the base end may be made thin and the tip may be made thick so that a recess is provided in the base end portion, and the cup peripheral edge of the brassiere can be accommodated in the recess so as to further reduce the displacement of the breast pad.

  In addition, it is preferable that the size of the pad body in the breast pad corresponds to the cup size of the brassiere used. In other words, it is better to use a brassiere that matches the size of the pad body. In the breast pad, the flange portion may be provided at the upper part of the peripheral edge of the pad main body, or may be provided on the entire peripheral edge of the pad main body.

  According to the breast pad, the side flange portion can be pressed against the chest in addition to the lower portion of the pad main body at the cup periphery of the brassiere when worn (in use). As a result, the breast pad in the brassiere cup can be prevented from shaking up and down due to walking and running when worn, and left and right shaking when moving the arm or twisting the body. Deviations in the vertical and horizontal directions and deviation due to rotation can be effectively reduced.

  In the breast pad, the flange portion is preferably provided on the side of the pad main body on the arm side (side portion side). In the breast pad, it is more preferable that the flange portion is provided so as to extend over both sides of the periphery of the pad main body. Thereby, a movement can be absorbed and attenuated more effectively by correcting the pressure of the pad body in the vicinity of the arm portion where the movement is large.

  In the breast pad, the pad body may be a hollow bag-like body. Thereby, weight reduction of a breast pad can be achieved and the shift | offset | difference of a mounting position can be reduced more.

  Further, in the breast pad, the pad main body may have a recess formed in the bottom surface, and a needle insertion valve through which an injection needle for air injection is inserted may be formed in the recess.

  Here, as the needle insertion valve in the breast pad, for example, a rubber material similar to that called “navel” or “musi” provided for injecting air into a tennis ball, volleyball, etc. Needle insertion valves, needle insertion valves made of medical and industrial materials, and the like can be widely used. The needle insertion valve may be the same member as the soft resin forming the bottom surface or may be a separate member, and is more preferably formed integrally with the recess.

  According to such a breast pad, since the needle insertion valve is formed in the concave portion on the bottom surface, the needle insertion valve can be prevented from coming into contact with the skin of the chest when worn. Furthermore, 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. In addition, since the recess is provided on the bottom surface, the recess can improve the elasticity of the bottom surface, and it is possible to prevent the flange portion from being pulled or loosened by changing the air pressure of the pad body, and to be displaced. It is easy to keep the feeling of pressing constant.

  A breast pad according to another aspect of the present invention is a soft resin breast pad used as a model for breast cancer palpation, in which a model affected area simulating the elasticity of breast cancer tissue is embedded and the surface is It has a pad main body having a convex curved surface imitating the shape of a breast, and a thin flange portion extending outward from the peripheral lower end of the pad main body.

  The flange portion in 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 pad body, and more preferably extended from the entire peripheral edge. Further, the extension length of the flange portion is preferably longer because 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 an actual chest.

  ADVANTAGE OF THE INVENTION According to this invention, the breast pad made from soft resins, such as silicone (rubber), which reduced the mounting | wearing deviation at the time of use can be provided. Moreover, according to this invention, the breast pad as a model for breast cancer palpation which was excellent in stability and was practical can be provided.

  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 has a pad main body 2 having a ridge shape (convex curved surface shape) imitating a breast on the surface 2a side, and a flange portion 3 extending in a ridge shape from the lower peripheral edge of the pad main body 2. The breast pad 1 is made of silicone (rubber).

  The pad main body 2 has a deformed circular shape (elliptical shape) imitating a planar view breast on the surface 2a side, and a recess is formed on the bottom surface 2b side as shown in a schematic sectional view in FIG. The size of the pad body 2 is determined according to the cup size of the brassiere used.

  The flange portion 3 is formed in a thin sheet shape extending outward from the lower end of the peripheral edge from the lower portion 2a1 of the pad main body 2 to the side portion (side side when mounted) 2a2. The thickness of the flange part 3 is not specifically limited, In this example, it is set as about 0.5-1 mm, and it is set as the taper shape made thin as the front-end | tip.

  The breast pad 1 can be integrally formed by, for example, applying liquid silicone over a plaster mold or pouring the liquid silicone into a plaster mold and curing it.

  In addition, you may form the convex part of the shape imitating a teat on the surface 2a of the pad main body 2, and it can be made closer to an actual chest shape by doing so. Further, the breast pad 1 may be colored in an arbitrary color.

  Next, another example of the breast pad according to the embodiment of the present invention will be described. As shown in the schematic front view and the schematic cross-sectional view in FIGS. 3 and 4, the breast pad 10 includes a pad main body 20 having a ridge shape (convex curved surface shape) imitating the breast on the surface side, and a peripheral edge of the pad main body 20. And a flange portion 30 extending in a bowl shape from the lower end. The breast pad 10 is made of silicone (rubber).

  The pad main body 20 is composed of a deformed circular (elliptical) outer skin part 20a imitating a breast in plan view, and a center part of the bottom skin part 20b on the back surface side, and the outer skin part 20a and the bottom skin part 20b. An internal space 50 is formed between the two, forming a hollow bag-like body as a whole.

  A recess 20c is formed near the center of the bottom skin 20b so as to be recessed toward the outer skin 20a. A space is formed in the internal space 50 between the recess 20c and the outer skin portion 20a. A needle insertion valve 40 is formed at the center of the recess 20c so that the air pressure in the internal space 50 can be adjusted by taking air into and out of the internal space 50. The needle insertion valve 40 may be formed of the same material as the bottom skin portion 20b, such as a thick knob-like portion, or other materials such as general-purpose needle insertion valves used in tennis balls, volleyball, etc. May be formed.

  The recess 20c provided at the center of the bottom skin portion 20b is preferably formed to a depth and width that prevents the needle insertion valve 40 provided in the recess 20c from contacting the skin of the user's chest when worn. By doing so, it is preferable also in terms of air permeability.

  The air can be taken into and out of the internal space 50 of the pad main body 20 by inserting the injection needle 70 for injecting air into the needle insertion valve 40. The air can be easily introduced by using, for example, a commercially available air dropper 60 for introducing air into a soft tennis ball or a manual pump such as a cylindrical pump for introducing air into volleyball. The size of the pad body 20 is determined according to the cup size of the brassiere used.

  The flange portion 30 is formed in a thin sheet shape extending outward from the lower end of the peripheral edge from the lower portion 20a1 of the pad main body 20 to both side portions 20a2, 20a3. The flange part 30 is also a peripheral part of the bottom skin part 20b, and is formed by bonding the skin part 20a from the surface side to the peripheral part of the bottom skin part 20b. The thickness of a flange part is not specifically limited, In this example, it is about 0.5-1 mm.

  Note that the thickness of the skin portion 20a and the bottom skin portion 20b may be appropriately determined in consideration of strength and weight, and is set to about 2 to 3 mm here.

  The breast pad 10 may be manufactured by, for example, applying liquid silicone on a plaster mold to form a skin portion 20a and a bottom skin portion 20b, and bonding them together using an appropriate adhesive. In addition, the folding | returning part 20a4 turned up inside is formed in the peripheral part of the skin part 20a, and it is used as a paste allowance at the time of bonding.
