Abstract
Description
Technical Field
[0001] This utility model relates to the medical field, specifically a bra for cosmetic purposes and to protect the skin in the radiotherapy area after breast cancer radiotherapy. Background Technology
[0002] The female breast is composed of skin, fibrous tissue, mammary glands, and fat. Breast cancer is a malignant tumor that occurs in the epithelial tissue of the mammary glands. 99% of breast cancer cases occur in women, while men account for only 1%. The number of patients with this disease is increasing year by year. The main treatment for breast cancer is to remove the part of the breast containing the lesion and to use radiotherapy and chemotherapy as adjuvant therapy.
[0003] Wearing a bra after surgery is a major issue for patients. If patients do not wear a bra, the skin in the radiation-treated area will rub against the clothing frequently, causing a series of problems such as skin damage, redness, swelling, inflammation, and pain. Moreover, patients may feel inferior when they do not wear a bra, and physical trauma can lead to psychological problems, making patients prone to a lack of self-confidence. However, traditional bras are not suitable for breast cancer patients after surgery, and traditional bras are inconvenient for observing and examining the skin in the radiation-treated area. Utility Model Content
[0004] The purpose of this invention is to provide a bra for cosmetic purposes and to protect the skin in the radiotherapy area after breast cancer radiotherapy. It can effectively support the original position of the breast, protect the skin in the radiotherapy area, and flexibly and conveniently adjust the degree of support according to the breast, the condition, and the surgical situation. It can also shape the contour to beautify the breast shape, while being functional and comfortable.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A bra for cosmetic purposes and skin protection in the radiation-treated area after breast cancer radiotherapy includes a garment body, a cushioning pad, and a support structure. The cushioning pad is detachably connected to the inner side of the garment body corresponding to the breast. The support structure includes a support strap, a positioning part, and an adjustment component. The support strap can wrap around the shoulder and lift the garment body upward. The positioning part is located on the garment body and connected to the support strap. The adjustment component is located at the support strap position to change the distance between the positioning part and the head. It also includes a prompting device for feedback on the adjustment range.
[0007] Compared with existing technologies, the bra designed for cosmetic purposes and skin protection in the radiation-treated area after breast cancer radiotherapy, which adopts the above-mentioned technical solution, has the following beneficial effects:
[0008] The bra of this invention, designed for cosmetic purposes and skin protection in the radiotherapy area after breast cancer radiotherapy, utilizes the flexible disassembly and assembly of the cushioning pads, as well as the lifting and adjustment functions of the support structure. While shaping and beautifying the breast to maintain the patient's image, it can effectively protect the skin in the radiotherapy area of the breast, avoiding a series of problems caused by direct friction between the skin in the radiotherapy area and the patient's clothing. It also has the functionality of protecting the postoperative skin and the comfort of wearing it.
[0009] Furthermore, by adjusting the combination of components and prompts, medical staff can clearly inform patients of the appropriate support height for daily use, based on their breast size, condition, and surgical history, or adjust it to a suitable support position during treatment. This ensures that the skin in the breast radiotherapy area is in a safe and comfortable position, increasing the protective effect on the skin in the radiotherapy area.
[0010] Preferably, the positioning part is a positioning ring piece located on the garment body corresponding to the breast position. The adjustment component includes a fixing part, a limiting protrusion, a locking groove, and a guide surface. The support strap is divided into a first strap body and a second strap body. The first strap body is connected to the portion of the garment body corresponding to the chest, and the second strap body is connected to the portion of the garment body corresponding to the back. The fixing part is located on the second strap body and has a through groove through which the first strap body can pass. The locking groove is located on the fixing part and communicates with the through groove. The limiting protrusion is elastically set, and there are multiple limiting protrusions. The multiple limiting protrusions are evenly spaced along the length direction of the first strap body. The guide surface is located on the side of the limiting protrusion facing the second strap body. When the first strap body passes through the through groove, the multiple limiting protrusions sequentially insert into or exit the locking groove. The indicator is a multiple color indicator mark respectively located on different limiting protrusions. Utilizing the telescopic characteristics of the limiting protrusions and the force transfer function of the guiding surface, the first belt is pulled towards the second belt to adjust the support height, while automatically locking the adjusted position. This method is convenient and efficient, allowing patients to operate it themselves daily and reducing the time spent by medical staff in treatment and nursing care. Furthermore, the intuitive and clear visual cues using color-coded indicators facilitate quick determination of the current support height, and the different heights indicated by different colors help clarify whether adjustment is needed.
[0011] Preferably, the positioning ring is located on the surface of the garment body away from the cushioning pad, and the cushioning pad is connected to both the garment body and the positioning ring via a quick-connect fitting. Because the quick-connect fitting is located between the garment body and the positioning ring, the skin of the breast and the radiotherapy area will not come into contact with the quick-connect fitting, thus preventing pressure sores or friction on the skin of the breast and the radiotherapy area.
[0012] Preferably, the quick-connect component is a reset piece made of memory material. The garment body and positioning ring both have positioning grooves through which the reset piece can pass. The cushioning pad has a shaping and stress-bearing layer on the side facing the positioning ring, and the positioning ring is connected to the shaping and stress-bearing layer. Utilizing the deformation and recoverability of the reset piece, it can be used repeatedly and can meet the need for temporary separation of the garment body and cushioning pad. The cushioning pad can be replaced or the garment body can be washed separately for reuse, increasing the service life of the structure.
[0013] Preferably, the inner side of the buffer pad is provided with a protective component, which includes a medication layer and a contact layer. One side of the medication layer can be attached to the inner side of the buffer pad, and the other side of the medication layer can be attached to or separated from the contact layer and the existing dressing. Multiple sets of protective components are provided, arranged sequentially and attached to the inner side of the buffer pad. For patients requiring medicated dressings, the treatment needs can be met while wearing the dressing by removing the contact layer and attaching the dressing. Furthermore, because there are multiple sets of protective components, multiple treatments can be performed, offering flexibility and convenience.
[0014] Preferably, all areas of the garment corresponding to the breast are transparent observation sections, and the cushioning pads are also transparent. A shielding layer can be detachably attached to the outer surface of the observation section. Utilizing the light transmittance of the transparent structure of the observation section, patients do not need to remove their entire bra; medical staff only need to open the shielding layer to directly and clearly understand the recovery status of the treatment area, improving the efficiency of postoperative observation.
[0015] Preferably, the edge of the shielding layer can be attached to the edge of the outer surface of the observation part.
[0016] Preferably, the shielding layer is composed of multiple sheet-like adhesive layers, and the multiple adhesive layers are attached and connected to each other.
[0017] Since different patients have different radiotherapy locations and ranges, the need for postoperative observation can be met by opening the corresponding layer.
[0018] Preferably, both the garment body and the cushioning pad have an antibacterial layer on their surfaces, and the antibacterial layer has multiple ventilation holes. Compared to traditional breast prostheses and bras, this effectively directs the heat and moisture generated by the skin's respiration outwards appropriately, avoiding prolonged exposure to heat and moisture that could cause discomfort or damage to the skin, and effectively preventing skin inflammation in the radiotherapy area.

[0025] The present invention will now be further described with reference to the accompanying drawings.
[0026] like Figures 1 to 5 The bra shown is for cosmetic purposes and to protect the skin in the radiation-treated area after breast cancer radiotherapy. It consists of a body 1, a cushioning pad 2, and a support structure.
[0027] The cushioning pad 2 is detachably connected to the inner side of the garment body 1 corresponding to the breast. The support structure includes a support strap 3, a positioning part, and an adjustment component 5. The support strap 3 can wrap around the shoulder and lift the garment body 1 upwards. The positioning part is located on the garment body 1 and connected to the support strap 3. The adjustment component 5 is located at the position of the support strap 3 to change the distance between the positioning part and the head.
[0028] The positioning part is a positioning ring 4 located on the garment body 1 at the position corresponding to the breast.
[0029] The adjustment component 5 includes a fixing part 50, a limiting protrusion 51, a locking groove 52, and a guide surface 53.
[0030] The support strap 3 is divided into a first strap body 30 and a second strap body 31. The first strap body 30 is connected to the part of the garment body 1 corresponding to the chest, and the second strap body 31 is connected to the part of the garment body 1 corresponding to the back. The fixing part 50 is provided on the second strap body 31, and the fixing part 50 is provided with a through groove 54 through which the first strap body 30 can pass. The locking groove 52 is provided on the fixing part 50, and the locking groove 52 communicates with the through groove 54. The limiting protrusions 51 are elastically provided, and there are multiple limiting protrusions 51. The multiple limiting protrusions 51 are evenly spaced along the length direction of the first strap body 30. The guide surface 53 is provided on the side of the limiting protrusions 51 facing the second strap body 31. When the first strap body 30 passes through the through groove 54, the multiple limiting protrusions 51 are sequentially inserted into or removed from the locking groove 52.
[0031] It also includes prompts for feedback on the adjustment range. These prompts can be scale markings, gear indicators, or color indicators. In this embodiment, to facilitate intuitive viewing and adjustment by medical staff and patients, the prompts are multiple color-coded indicators 6 respectively located on different limiting protrusions 51. Specifically, in this embodiment… Figure 4 As shown, the color markings on the three limiting protrusions 51 are light yellow, light red, and light purple, respectively.
[0032] The positioning ring 4 is located on the surface of the garment body 1 away from the cushioning pad 2. The cushioning pad 2 is connected to both the garment body 1 and the positioning ring 4 via a quick-connect fitting. The quick-connect fitting is a reset piece 7 made of memory material (such as memory metal or shape memory polymer). Both the garment body 1 and the positioning ring 4 are provided with positioning grooves 70 through which the reset piece 7 can pass. The side of the cushioning pad 2 facing the positioning ring 4 is provided with a shaping and stress-bearing layer 20, and the positioning ring 4 is connected to the shaping and stress-bearing layer 20.
[0033] To assist in the recovery of the buffer pad 2 in this embodiment, a protective component 8 is also provided on the inner side for easy application of the dressing. The protective component 8 includes a drug application layer 80 and a contact layer 81. One side of the drug application layer 80 can be attached to the inner side of the buffer pad 2, and the other side of the drug application layer 80 can be attached to or separated from the contact layer 81 and the existing dressing. Multiple sets of protective components 8 are provided, and multiple sets of protective components 8 are arranged in sequence and attached to the inner side of the buffer pad 2.
[0034] Furthermore, to facilitate doctors' observation and examination of the skin in the radiotherapy area, the garment 1 has a transparent observation section 10 corresponding to the breast, and the cushioning pad 2 is also transparent. A shielding layer 9 is detachably connected to the outer surface of the observation section 10. In this embodiment, the shielding layer 9 is attached by an adhesive method, which is easy to remove and restore the shielding state. In order to avoid pulling on the radiotherapy site as much as possible, the edge of the shielding layer 9 can be attached and fixed to the edge of the outer surface of the observation section 10.
[0035] In addition, since different patients have different radiotherapy locations and ranges, the shielding layer 9 is divided into multiple sheet-like adhesive layers 90, and the multiple adhesive layers 90 are attached and connected to each other. That is, in this embodiment, only the part of the adhesive layer 90 corresponding to the radiotherapy area needs to be opened to observe and check the recovery status.
[0036] In addition, both the garment body 1 and the cushioning pad 2 have an antibacterial layer on their surfaces, and the antibacterial layer has multiple air vents.
[0037] In this case, since breast cancer surgery may involve total, partial, or no mastectomy, the cosmetic aspect refers to shaping and beautifying the breast using the cushioning pad 2. During use, a suitable garment body 1 and cushioning pad 2 are first selected. The cushioning pad 2 supports the original position of the breast. Applying force causes the repositioning piece 7 to deform or close. The shaping and support layer 20 of the cushioning pad 2 is placed inside the garment body 1, and the repositioning piece 7 passes through the positioning groove 70 to reposition itself, forming a shape as shown... Figure 4 The state shown.
[0038] When not in use, part of the first strap 30 is located in the groove 54 of the fixing part 50, and one of the limiting protrusions 51 is located in the locking groove 52. After the garment 1 is initially put on the chest, if the height of the breast support needs to be increased, the first strap 30 can be pulled directly towards the second strap 31. Part of the force will be transferred to the guide surface 53, so that the limiting protrusion 51 in the current locking groove 52 is forced to retract into the groove 54, automatically and temporarily releasing the locking state, and allowing the first strap 30 to move in the groove 54. When the subsequent limiting protrusion 51 contacts the fixing part 50, it will also be forced to retract into the groove 54. The subsequent limiting protrusion 51 moves synchronously with the first strap 30. When the subsequent limiting protrusion 51 moves to the opening of the locking groove 52, the limiting protrusion 51 is not restricted by the inner wall of the groove 54, and the limiting protrusion 51 automatically extends and locks into the locking groove 52, realizing automatic locking after the support strap 3 is adjusted. If it is necessary to lower the support height of the breast, press the limiting protrusion 51 in the current locking groove 52. During this forward and reverse adjustment process, by checking the color indicator 6 corresponding to the limiting protrusion 51 in the current locking groove 52, and the support status corresponding to each color indicator 6, medical staff can inform the family whether adjustment is needed or assist in adjusting the support height during treatment, based on the patient's surgical situation and condition.
[0039] If a dressing is needed, the inner contact layer 81 can be peeled off to expose the medication layer 80. The dressing can then be attached to the medication layer 80 for wear. When medication is not needed, the dressing along with the adjacent medication layer 80 can be peeled off to expose the other set of inner protective components 8. At this time, the other set of contact layers 81 will be exposed, and the patient can wear the dressing normally to support the breast. If medical staff need to observe and examine the radiotherapy area, they only need to open the portion of the dressing 90 corresponding to the radiotherapy area to observe and examine the recovery.
[0040] The above description is a preferred embodiment of the present utility model. For those skilled in the art, several modifications and improvements can be made without departing from the principle of the present utility model, and these should also be considered within the protection scope of the present utility model.
