A system for preserving functionality of a skin-engageable element for attachment to a skin portion of a user during storage including a skin-engageable element and a protective element having discrete portions projecting therefrom. The discrete portions are adapted to engage with through-going passages in an adhesive layer of the skin-engageable element, and ensure that the passages are open and passable when the protective element is removed before use of the skin-engageable element. A protective element attachable to a proximal adhesive side of a skin-engageable element for attachment to a skin portion of a user is also disclosed.

An ostomy pouch emptying device which has a receiver for receiving effluent from an ostomy pouch. The emptying device may accommodate disposable receptacles, such as emesis bags with integrated rims, or may directly interface with a receptacle such as a toilet bowl. The device can be used while standing or sitting, and may be secured to a wall or placed atop a lap of the user. An embodiment could also provide a portable system for disposing of the effluent from the ostomy pouch.
