Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a nipple protection dressing for breast reconstruction. Background Technology

[0002] With the development of medical technology and a deeper understanding of breast cancer treatment, more and more breast cancer patients are choosing breast reconstruction surgery to improve their postoperative quality of life and physical appearance. Among these, nipple-areola-sparing breast cancer reconstruction surgery has become possible and is widely used clinically. This surgical approach can preserve the nipple-areola complex while removing breast tissue, thus maintaining the natural appearance of the breast postoperatively. Although the technique of nipple-areola-sparing breast cancer reconstruction surgery is relatively mature, complications can still occur, such as nipple-areola necrosis, infection, and implant displacement. In particular, ischemic necrosis of the nipple-areola significantly affects the surgical outcome. Besides the meticulous intraoperative technique, selection of an appropriate incision, preservation of an appropriate glandular thickness, and avoidance of equipment that may damage blood supply, postoperative care is equally crucial. Postoperative care measures (such as appropriate bandaging and wearing pressure bras) help protect blood supply, but their effectiveness depends on patient cooperation and the quality of care. Sometimes, improper bandaging or wearing of pressure bras can actually compress the nipple, affecting blood supply. Some clinicians use a method of cutting the end of a syringe into a small piece and placing it over the nipple. The drawbacks are that it is not easy to fix and it is prone to displacement; moreover, the plastic material of the syringe is relatively hard, which can cause pressure and ischemia in the areola area. Others cut holes in the nipple area of ​​the strap or bra, which also has the disadvantages of being prone to displacement and damaging clothing. Utility Model Content

[0003] In order to overcome the problems existing in the prior art, the purpose of this utility model is to provide a nipple protection dressing for breast reconstruction, which can effectively protect the nipple after reconstruction, reduce the occurrence of ischemic necrosis, and provide a comfortable wearing experience.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A nipple protection dressing for breast reconstruction includes a sheet-like soft raised portion and a soft covering portion. The soft covering portion is located at the bottom of the soft raised portion, and the maximum thickness of the soft raised portion is 2±0.5 cm. A first through hole is provided at the center of the soft raised portion, and a second through hole is provided at the center of the soft covering portion. The diameter of the second through hole is larger than that of the first through hole. The first through hole and the second through hole are concentrically arranged to accommodate the nipple. At least a portion of the bottom surface of the soft covering portion is provided with an adhesive layer.

[0005] Furthermore, the outer edge of the soft protrusion is circular, elliptical, or a deformed elliptical shape.

[0006] Furthermore, the soft raised portion is made of cotton material. Cotton material is soft and breathable, facilitating postoperative recovery.

[0007] Furthermore, an anti-stick backing film is affixed to the adhesive layer to prevent contamination. Simply peel off the backing film before use.

[0008] Furthermore, the bottom surface of the soft raised portion and the top surface of the soft covering portion are bonded together.

[0009] Furthermore, the top edge of the soft raised portion and the top edge of the soft covered portion are bonded together by an annular adhesive strip.

[0010] Furthermore, at least one of the inner ring of the soft raised portion and the bottom ring near the first through hole is provided with an annular drug storage layer that directly contacts the breast skin. The drug storage layer stores drugs and can directly act on the breast in contact.

[0011] Furthermore, the diameter of the first through hole is 3±0.3 cm, which allows the nipple to be located therein without being compressed.

[0012] Furthermore, the diameter of the second through hole is 5 ± 0.3 cm.

[0013] Compared with existing technologies, this invention has the following advantages: The nipple protection dressing of this invention has good fixation; both its soft raised portion and soft covering portion are made of soft material, allowing it to fit closely to the areola and avoid causing additional damage to the breast. The thickness of the soft raised portion is just right, and it has a first through-hole in the middle, forming a protective ring around the nipple, effectively resisting external pressure. This invention can further provide a drug-reservoir layer at the bottom of the soft raised portion near the first through-hole, allowing the medication to be directly applied to the nipple and areola after surgery, thereby further improving the postoperative recovery effect.

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0020] In the description of this utility model, it should be understood that the terms "center," "length," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In this utility model, unless otherwise expressly specified and limited, "upper" or "lower" of the first feature than the second feature may include direct contact between the first and second features, or it may include contact between the first and second features not being in direct contact but through another feature between them.

[0021] As one embodiment of this utility model, such as Figures 1-3 As shown, a nipple protection dressing for breast reconstruction includes a sheet-like soft raised portion 1 and a soft covering portion 3. The soft covering portion 3 is located at the bottom of the soft raised portion 1, and the maximum thickness of the soft raised portion 1 is 2 ± 0.5 cm. A first through-hole 2 is provided at the center of the soft raised portion 1, and a second through-hole is provided at the center of the soft covering portion 3. The diameter of the second through-hole is larger than that of the first through-hole 2. The diameter of the first through-hole 2 is set to 3 ± 0.3 cm to allow the nipple to be placed within it without pressure; the diameter of the second through-hole is set to 5 ± 0.3 cm. The first through-hole 2 and the second through-hole are concentrically arranged to accommodate the nipple. At least part of the bottom surface of the soft covering portion 3 is provided with an adhesive layer, which contacts the breast skin. The adhesive layer can use existing medical adhesives such as acrylic pressure-sensitive adhesives. The wearing process of this utility model is as follows: align the first through hole 2 with the nipple, align the back of the nipple protection patch (i.e. the bottom surface of the soft covering part 3) with the areola, and use the adhesive layer to adhere the nipple protection patch to the breast skin.

[0022] Based on the above embodiments, a soft raised portion 1 of suitable thickness is provided, and a first through hole 2 is provided in the middle of the soft raised portion 1, and the size of the first through hole 2 is limited to provide space for the nipple and prevent the nipple from being squeezed by external force and rubbed by clothing. In addition, the soft covering portion 3 is made of soft material and is thin, which can better fit the breast skin.

[0023] The soft raised portion 1 is preferably made of cotton material, which is soft and breathable. The soft covering portion 3 uses existing medical dressings, such as polyethylene nonwoven fabric or polypropylene nonwoven fabric, which are soft, not easily deformed, and non-irritating to the skin, further ensuring comfort and protection during postoperative care.

[0024] As in the above embodiment, the outer edge of the soft raised portion 1 is circular, and the outer edge of the soft covering portion 3 is also circular. As another embodiment, see [link to embodiment]. Figure 4 The outer edges of the soft raised portion 1 and the soft covering portion 3 are deformed elliptical shapes, with the minor axis of the ellipse concave towards the center. The outer edge shapes of the soft raised portion 1 and the soft covering portion 3 in this invention are not specifically limited. Because the materials of the soft raised portion 1 and the soft covering portion 3 are soft, they can be made into various shapes to conform to the breast. The specific shape used can be determined according to the application requirements.

[0025] To prevent the adhesive layer of the nipple protection patch from becoming contaminated or sticking together during storage or transportation, an anti-stick backing film is also attached to the adhesive layer. To use, simply peel off the backing film and apply the patch.

[0026] To further enhance the functionality of the nipple protection dressing, in some embodiments, at least one of the inner ring of the soft raised portion 1 and the bottom ring near the first through-hole 2 is provided with an annular drug-reservoir layer 4 that directly contacts the breast skin. The diameter of the aforementioned second through-hole is larger than that of the first through-hole 2, providing space for the drug-reservoir layer 4. The drug-reservoir layer 4 preferably comprises a gel and a drug contained therein, enabling the drug to be released continuously and stably and act on the breast tissue. The drug-reservoir layer 4 can be in the form of a paste, gel, or other solid form. It preferably stores a vasodilator, such as nitroglycerin, which can continuously improve blood supply to the nipple and promote wound healing and recovery. The gel can be any known gel, such as polyacrylic acid gels (e.g., carbomer), chitosan gel, etc.

[0027] In summary, the nipple protection dressing for breast reconstruction provided by this utility model, through its reasonable structural design, effectively protects the nipple, reduces the occurrence of ischemic necrosis, and provides a comfortable wearing experience, offering a safer and more reliable postoperative care solution for patients after breast cancer reconstruction surgery.
