A medical device and methods of applying a barrier product are described that allow for improved adhesion of a barrier product to skin in the area of a wound such as a stoma, fistula or other opening in human skin. The medical devices herein include a handle; a roller arm; and a roller head. The exterior surface of the roller head is configured to enhance adhesion of a barrier product to an area of mammal skin near a wound opening. Kits and other options are described for facilitating use of the medical devices by patients having wounds or medical professionals.

A shaft securing mechanism is provided that includes pins, bearings or other securing members that are biased inwardly at an angle with respect to the axis of the shaft being engaged by the mechanism. The angled orientation of the engagement of the pins with the shaft enables the pins to more securely hold the shaft relative to the handle without significant slop or play in the lateral or longitudinal directions. The mechanism also includes a tapered inner surface to increase the ease of alignment of the shaft with the mechanism, which allows the shaft to be engaged with the handle by only pressing and rotating the shaft into the mechanism within the handle.

A prying head is provided in the present disclosure. The prying head, which is used in cooperation with a hand tool, includes a prying portion, a supporting portion and an assembling portion. The prying portion includes a ground-abutting surface and an article-abutting surface. The article-abutting surface is connected to the ground-abutting surface to form a sharp edge. The supporting portion is connected to the prying portion and includes a curved surface. The curved surface is connected to the ground-abutting surface and the article-abutting surface, so as to make an end of the supporting portion away from the sharp edge into a curved form. The assembling portion is connected to the supporting portion and includes a blind hole. The blind hole is recessed from an end of the assembling portion away from the sharp edge.
