A method for providing negative pressure wound therapy (NPWT) and phototherapy to a wound includes providing NPWT by drawing a negative pressure at the wound using a pump. The method also includes providing phototherapy by operating a light source to provide light having a specific wavelength to the wound. Drawing the negative pressure at the wound for NPWT changes a surface topology of the wound to expose different surfaces of the wound to the light for phototherapy.

A chest seal is provided, including a release layer; an adhesive layer, a center of the adhesive layer being opened with an exhaust through hole; and a backing layer. The adhesive layer is arranged between the release layer and the backing layer; the backing layer includes a lower backing layer and a soft backing layer; the lower backing layer and the soft backing layer are staggered and form an overlapping area; the overlapping area includes a connection area and a non-connection area; and the lower backing layer is arranged above the adhesive layer and does not completely block the exhaust through hole. The chest seal can prevent external air from entering the chest cavity and discharge the effusion in the chest cavity when a penetrating wound is formed in the chest cavity through the structural design between the exhaust through hole, the lower backing layer, and the soft backing layer.

Disclosed herein are devices and methods for protecting reconstructed nipples, typically post-surgery. The nipple protector may include a circular base portion and an annular ridge concentrically disposed to define a central aperture. The nipple protector In may further include an adhesive layer disposed on a bottom surface of the base portion for adhering the nipple protector to an area surrounding the reconstructed nipple. The nipple protector is fashioned to allow for direct access to the new nipple, which facilitates application of antibiotic ointments. The nipple protector softly adheres to the skin to provide flexible, adherent, comfortable, and water tolerant usage.
