Abstract

An ostomy coupling device comprises a faceplate for placing over the stoma including a neck having outwardly facing threads, and a generally cylindrically shaped screw coupling having threads on the inner surface thereof. The narrow portion of an ostomy pouch is placed over the neck, and the screw coupling is thereafter rotated onto the neck, whereby the aperture collar of the pouch is conformed to the space between the matching threads of the screw coupling and faceplate, thereby providing a seal between the pouch and the stomal aperture.
