An adhesive wafer (10) for an ostomy device, the wafer comprising a skin-facing adhesive layer (40), a backing layer (30) on the non-skin-facing side of the adhesive layer, and a hole (60) for accommodating a stoma. On the central portion of the backing layer is located a release layer (110) being configured to release a neutralizer. The neutralizer is capable of neutralizing or at least minimizing the level of skin or adhesive aggressiveness of the output.

The present invention relates to a magnesium alloy material, which is an in situ magnesium hydroxide nanosheet layer modified magnesium alloy. The material is prepared from a magnesium alloy through a hydrothermal reaction under alkaline condition. The protective effect of the in situ formed magnesium hydroxide nanosheet layer structure results in remarkably enhanced corrosion resistance of the magnesium alloy, meanwhile the biocompatibility can also be significantly improved since the release rate of magnesium ion can be significantly reduced. In addition, the two-dimensional nanolayer structure has a non-releasing physical antibacterial property depending on contact. Therefore, the magnesium alloy material according to the present invention has an extremely great application prospect in the field of medical implant.
