Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
The artificial breast according to the present embodiment can be mounted on the chest by a patient whose breast has been removed by surgery, for example. As shown in FIG. 1, the shape determination step S1 and the outer contour of the determined shape are included. It is manufactured through a measuring step S2 for measuring and a cutting step S3 for cutting the artificial breast based on the measured outer contour shape.

  The shape determination step S1 is a step in which the patient can determine the shape of the obtained artificial breast. The shape determination is performed by using the laminated member 1 and the rectangular sheet member 2 each made of urethane, as shown in FIG. Done with. The laminated member 1 is made of a plurality of circular (or may be oval) sheet-like urethanes in a plan view that can be laminated, and the corresponding member 3 is a single rectangular sheet member made of urethane. Can be obtained by cutting the patient into an arbitrary shape, and these constitute a simulated member for manufacturing the urethane artificial breast according to this embodiment.

  Specifically, as shown in FIG. 3, the laminated member 1 has a plurality of diameters that are set to be smaller in the order of D1 to D6 and have different diameters so as to form a mountain shape in the laminated state (this embodiment). 6) are made of sheet urethane 1a to 1f, which can be arbitrarily selected by the patient to be in a laminated state (see FIG. 5). That is, when the bulge size of the artificial breast that the patient wants to obtain is increased, a large number of laminated members 1 are selected and laminated, while when the bulge size is desired to be reduced, a smaller number of laminated members 1 are selected and It is laminated so that it is at an arbitrary position.

  Thereby, the laminated member 1 in a laminated state forms a mountain shape as a whole, and a laminated product simulated by the patient's breast can be obtained. In addition, when laminating, adhesive or double-sided tape or the like is applied or adhered to the back surface of each sheet-like urethane 1a to 1f so that each sheet-like urethane 1a to 1f after lamination can maintain a mountain shape. deep. Moreover, before lamination | stacking, a patient can cut each sheet-like urethane 1a-1f into desired shapes with cutting tools, such as scissors and a cutter, and can also obtain arbitrary shapes as a whole.

  As shown in FIG. 4, when the patient cuts the rectangular sheet member 2 into a desired shape with a cutting tool such as scissors or a cutter, the corresponding member 3 can be applied to a defect site in the chest of the patient caused by surgery, for example. The shape is made to correspond. However, as shown in FIG. 5, the corresponding member 3 can be laminated on the lowest part of the mountain shape formed by the laminated member 1 and should be bonded with the above-described adhesive or double-sided tape.

  As described above, since the overall shape of the artificial breast to be obtained can be determined by laminating the simulated members composed of the laminated member 1 and the corresponding member 3, the patient can be completely removed from the environment. The person can determine the shape of the artificial breast and protect the privacy of the patient. In addition, for example, if the simulated member (the laminated member 1 and the corresponding member 3) is sent as a kit to the patient's home, and the patient determines the shape and then returns it, the patient's privacy can be further protected. it can.

  The mountain shape obtained by laminating the laminated member 1 and the corresponding member 3 as described above is sent to a processing process such as a factory, and an artificial breast that can be worn by the patient is manufactured based on the outer contour of the mountain shape. . That is, a mountain shape composed of the laminated member 1 and the corresponding member 3 is measured three-dimensionally (measurement step S2), and block urethane (rectangular or cubic foamed urethane) is cut based on the measured value ( In the cutting step S3), an integral and three-dimensional urethane artificial breast 4 as shown in FIG. 6 is manufactured.

The urethane artificial breast 4 includes a mountain-shaped portion 4a formed following the outer contour of the laminated member 1 in a laminated state, and a corresponding portion 4b formed following the planar shape of the corresponding member 3. And can be worn by the patient on the chest. However, the laminated member 1 in the laminated state is formed with a plurality of step shapes for each layered portion, but the step shape is leveled so as to simulate a human breast, and the whole is formed into a gentle mountain-shaped portion 4a. .

  Block urethane is made of urethane containing a predetermined amount of bamboo charcoal (a urethane material containing a predetermined amount of bamboo charcoal and foamed into a block shape). The artificial breast also contains a predetermined amount of bamboo charcoal. Thus, since the urethane artificial breast according to the present embodiment contains bamboo charcoal, a high antibacterial effect, deodorizing effect, or fungicidal effect can be exhibited by the action of the bamboo charcoal.

  Here, in this embodiment, the laminated member 1 and the corresponding member 3 are substantially the same as the block-like urethane (for example, the degree of foaming or the content of bamboo charcoal). Thereby, even in an environment where a third party can be completely blocked, it is easy for the patient to image the artificial breast finally obtained, and it is possible to easily determine an arbitrary shape. Note that the laminated member 1 and the corresponding member 3 may have the same texture as the block urethane and do not contain bamboo charcoal.

  As described above, according to the urethane artificial breast according to the present embodiment, a mold for molding urethane is not necessary, so that the manufacturing cost can be reduced, and the number of laminated members 1 and the number of the laminated members 1 can be arranged. Because it can be laminated with, shape a mountain shape of arbitrary height and shape that matches the patient's chest, and block shape urethane can be cut based on the outer shape of the molded mountain shape to obtain an artificial breast, The shape can be determined by the patient alone. In addition, the patient can determine the shape of the artificial breast in an environment where the third party can be completely blocked, and the privacy of the patient can be further protected.

  Furthermore, according to the present embodiment, a corresponding member having a shape corresponding to the defect site in the patient's chest is stacked on the lowest portion of the mountain shape, and an artificial breast is formed based on the outer shape of the mountain shape including the corresponding member. Therefore, it is possible to obtain an artificial breast that also matches the chest of a patient who has lost in a surgical operation or the like in an environment that can completely block a third party.

  Furthermore, the urethane artificial breast according to the present embodiment is able to reliably adhere to the wearer's skin and suppress displacement due to its low resilience elasticity, and is light in weight. Can be reduced. In particular, in the present embodiment, since the corresponding member formed integrally with the artificial breast matches the chest of the patient who has been lost due to surgery or the like, it is possible to further improve the wearability by further suppressing the deviation and the loss Chest protection and body shape correction can be achieved. The urethane artificial breast according to the present embodiment is highly hygienic because it is highly breathable and can suppress the stuffiness during wearing and can be repeatedly washed.

  As mentioned above, although this embodiment was described, this invention is not limited to this, For example, it is good also as what is not provided with the corresponding member 3 in a simulation member, and is only the laminated member 1 which consists of sheet-like urethane 1a-1f. Further, the number of sheet urethanes that can be laminated or the thickness of each sheet urethane can be arbitrarily set. Furthermore, in the urethane artificial breast according to the present embodiment, bamboo charcoal is contained in a predetermined amount, but other materials (for example, pigments for coloring) may be contained.

  Laminating members made of a plurality of circular or elliptical sheet-like urethanes in a plan view that can be laminated and having different diameters to form a mountain shape in the laminated state are laminated in an arbitrary number and arrangement. A urethane artificial breast obtained by forming a mountain shape of arbitrary height and shape according to the chest of the patient and cutting block urethane based on the outer shape of the molded mountain shape, or the urethane artificial As long as it is a simulated member for manufacturing a breast, it can be applied to a member having a different external shape or one having other functions.
