The corrective orthopedic bra (Fig. 1a) is made in the form of an anthropometrically corresponding three-dimensional configuration of the mammary glands of an adjacent frameless multilayer bra. The product structurally consists of one upper (4), two lower (5, 6) and one side (7) parts of the cups, cut-off barrels (2), belt (1), adjustable straps (3). Corrective orthopedic bra with front closure (Fig. 16) on hooks (13) and multi-row loops (14). The location of the loops in two / three rows allows you to adjust the required degree of compression of the product. On the wrong side of the cups of the orthopedic bra (Fig. 16) there are symmetrical convex set-in pockets for fixing breast exoprostheses. The convex shape of the pockets is structurally solved by two parts: upper (9) and lower (10), connected along a curved cut (11). This configuration of the pockets makes it possible to place exoprostheses of any shape inside the product (Fig. 2).

The degree of pressing the edges of the corrective orthopedic bra is provided by elastic bands stitched along the upper (12a) and lower (12b) edges.

Between the outer and inner layers of the package of elastic materials of each cup of the corrective orthopedic bra, there is a removable three-layer cover (15) attached to the product (Fig. 3a). The connection of the removable cover with the product (Fig. 5a) is made by means of hooks (28) and loops (27) (Fig. 5b). For convenience of positioning the removable cover inside the corrective orthopedic bra, inlets (29, 30) are provided along the upper edge of the upper part of the pocket (9) and the lower edge of the lower part of the pocket (10) (Fig. 1b).

Removable cover - a three-layer product, made of elastic cotton material, with differences on the outer and inner sides. Removable pouch contains three pockets. On the inside of the cover there is an inner pocket (Fig. 4) intended for the exoprosthesis (1b).

The pocket consists of two parts (23, 24) with an entrance (25) in the central part of the part (Fig. 4a), which provides convenient positioning of the exoprosthesis (Fig. 4b).

On the outside of the cover are pockets:

- side (17) (Fig. 7d) - for the side shape-setting gasket (31),

- upper (18) (Fig. 8d) - for the upper shaping gasket (33),

- lower (19) (Fig. 10) - to accommodate the weighting agent (35).

The configuration of the details of the bra pockets (9, 10) located on the wrong side of the corrective orthopedic bra (Fig. 1b) allows you to place silicone prostheses (16) (Fig. 3a, Fig. 4b) of any configuration, including asymmetrical ones (Fig. . 2), the purpose of which is the general correction of the spatial shape of the woman's body after mastectomy. Depending on the prevalence of the tumor, during the operation on the woman's body, the affected areas (nearby soft tissues, adipose tissue, lymph nodes, muscle tissue, skin, etc.) are surgically removed, which significantly changes the relief of the body surface and requires visual correction.

Typical models of breast exoprostheses: 1) postoperative (textile), 2) for daily wear (silicone), 3) lightweight silicone (for sports, pool, etc.).

Typical forms of silicone exoprostheses: 1) triangular, drop-shaped, rounded; 2) symmetrical and asymmetrical (Fig. 2). Typical forms of silicone exoprostheses do not take into account the variety of options for the spatial configuration of the bodies of operated women. Most often, women complain about the acquired asymmetry in the topography of the fat layer in the healthy and operated areas of the figure, especially in the chest area (top, along the edges) and armpits. Some women, in order to even out the relief of the body in the operated area and achieve symmetry of the shape of the breast on the left and on the right, use liners made in a handicraft way, which are trimmings of the filler extracted from lightweight textile prostheses. Women put these pads in the pocket of an orthopedic bra next to the silicone exoprosthesis. Such a solution of the confection package does not provide reliable fixation of handicraft pads, there is a possibility of their mobility, and as a result of the displacement, asymmetry in the spatial configuration of the healthy and operated sides of the body increases.

The weight of silicone exoprostheses is comparable to the weight of a healthy female breast. Silicone exoprostheses of typical shape visually correct the surface topography on the operated side. However, there are individual differences in tumor involvement of the mammary glands, and, accordingly, a variety of postoperative body configurations after surgical treatment. Therefore, it is impossible to take into account all variants of the acquired new morphology of the woman's body in standard forms of exoprostheses. Services for the manufacture of individual silicone breast exoprostheses are provided by some enterprises that produce standard products. However, the cost of such exoprostheses significantly exceeds the cost of their standard counterparts. Therefore, handicraft-made pads remain available to many women as a means of smoothing asymmetry.

In the early postoperative period, women have to use soft textile prostheses of the mammary glands, the spatial shape of which is universal, and is created by a lightweight filler made of hypoallergenic fibers, to eliminate the imbalance in the body configuration. The weight of such prostheses is too small. Some women, in order to eliminate excessive mobility of the textile prosthesis when walking, use additional weighting agents made in a handicraft way, which partially compensates for the weight imbalance of the body after the operation. Such weighting agents are placed in a bra next to a textile prosthesis. At the same time, both inserts often shift relative to each other when the woman moves, which increases discomfort. A typical constructive and technological solution of well-known models of orthopedic bras does not provide for the embedding of weighting agents in the product.

The confection package of a corrective orthopedic bra includes a removable cover attached to the product by means of hooks and loops between the layers of pocket materials in one or both cups of the bra (depending on the outcome of the operation, when one or both breasts are removed). The removable cover is three-layer (Fig. 3), and on the outer side it is two-layer and contains three pockets - side, top and bottom (Fig. 6b) for placing two form-setting two-layer gaskets - side (31) (Fig. 7a) and top ( 33) (Fig. 8a), with fillers from textile materials, for example, from synthetic winterizer; and a two-layer weighting agent (35) (Fig. 9a), filled with silicone and/or other materials. On the inside, the cover contains one pocket (Fig. 4), assembled from two parts: central (Fig. 6c) and side (Fig. 6d). A pocket on the inside of the cover serves to fasten the exoprosthesis (Fig. 4b).

In the side pocket (17) (Fig. 7d) of the cover for correcting the relief of the operated body through the inlet (21), a side shape-setting gasket (31) (Fig. 7a) is placed. On the inside, there is a lateral form-setting gasket with an opening (32) (Fig. 7b) for adjusting the volume of the filler. Technologically, the lateral shaping pad can be made both with closed sections (Fig. 7b) and with open sections (Fig. 7c), machined on a special machine.

In the upper pocket (18) of the cover (Fig. 8d) of the cover for correcting the relief of the operated body through the inlet (22) place the upper shape-setting gasket (33) (Fig. 8a). On the inner side of the upper form-setting gasket with a hole (34) (Fig. 8b) to control the volume of the filler. Technologically, the upper form-setting gasket can be made both with closed sections (Fig. 8b) and with open sections (Fig. 8c), processed on a special machine.

In the lower pocket (19) of the cover (Fig. 10) of the cover for correcting the relief of the operated body, a weighting agent (35) is placed through the inlet (20) (Fig. 9a). On the inside, a weighting agent with a hole (36) (Fig. 9b). Technologically, the weighting agent can be made both with closed sections (Fig. 9b) and with open sections (Fig. 9c), processed on a special machine. The two-layer weighting material is filled with a silicone liner.

Removable cover assembly algorithm:

- overcast sections (inlets) of the side (17), upper (18) and lower (19) pockets (Fig. 3) on the upper part of the cover;

- connect the two upper parts of the cover on a cover-seam machine along a chalked auxiliary line to form a side (17) (Fig. 7d) and upper (18) (Fig. 8d) pockets designed to accommodate two form-setting two-layer gaskets - side (31) and top (33);

- stitch a tuck on the overlock (Fig. 6a) on the upper part of the cover;

- connect the two upper parts of the cover on a cover-seam machine along a chalked auxiliary line to form a lower pocket (19) (Fig. 10) designed to accommodate the weighting agent (35);

- the central (23) and side (24) parts of the pocket along the inside of the cover (Fig. 4), fold in half, wrong side inward and put one on top of the other, aligning the fold of the central part of the pocket with a cut on the side part of the pocket, to form an inlet (25) (Fig. 4b), designed to accommodate the exoprosthesis;

- put the assembled upper part of the cover with the wrong side on the assembled inner part of the cover, equalize and overcast the cuts on the overlock;

- thread the shoulder strap into the hook (27) (Fig. 10) and sew on the top seam of the cover.

The proposed constructive and technological solution of the corrective orthopedic bra allows you to securely fix the breast exoprosthesis inside the product and, if necessary, shaping pads placed inside the removable cover, depending on the individual characteristics of the body configuration in the postoperative period, on the left or right side of the removable cover.

Breast exoprostheses for permanent wear are made of medical silicone placed in an elastic shell. The exoprosthesis, placed in the product and heated by the heat of the woman's body, acquires little mobility, which imitates the natural swaying of the breast, similar to that of a healthy breast. The disadvantage of silicone exoprostheses is the low friction characteristics of its shell, as a result, the mobility of the exoprosthesis inside the bra is often observed, and sometimes its slipping. Placing the exoprosthesis inside the cover makes it possible to give it additional stability inside the corrective orthopedic bra due to: 1) increasing friction between the outer and inner layers of the product and the corresponding layers of the cover, which is an additional shell of the prosthesis, and 2) fastening the cover to the main part of the product.

A removable cover can also be used in the initial postoperative period, when women are recommended to wear lightweight prostheses filled with textile fibers. The presence in the pocket of the removable cover of the hole (25) located between the details of the pocket (23, 24) (Fig. 4) allows the woman to independently adjust the volume of the shape of the bra cup by positioning inside the additional amount of filler of the textile liner. In the case of using an orthopedic corrective bra in the early postoperative period, complete with a textile breast exoprosthesis, a weighting agent (35) (Fig. 10) is placed in the pocket (19) to correct the weight imbalance.

The corrective orthopedic bra is a safe product, because it is made of elastic knitted materials with a compression effect. Preservation of the spatial shape of the product provides a multilayer package of materials containing natural fibers. High anthropometric conformity is achieved by three-dimensional design of the three-dimensional form of a corrective orthopedic bra in the environment of a three-dimensional graphic system based on a personalized avatar - a digital twin of a woman's body after a mastectomy. As a result of 3D design (Fig. 11), an individual shape is generated for both the adjacent bra and the shape of the inserts - shaping pads and weighting material. The high anthropometric conformity of the product will save the woman in the postoperative period from internal discomfort and improve her quality of life.

The proposed corrective orthopedic bra has high competitive advantages over imported products due to the use of innovative constructive and technological methods for shaping and confectioning the product, taking into account the configuration of the thoracic region of the body of Russian women after mastectomy. As part of the import substitution program, the production of innovative corrective orthopedic bras in terms of design and technological solutions is aimed at saturating the domestic market with high quality and design rehabilitation products.
