Abstract
The ostomy system includes a pouch that is adhesively coupled to a mounting wafer. The mounting wafer has a landing zone film formed of releasable plastic and the pouch has a face plate with a resealable adhesive that secures to the landing zone of the mounting wafer. The landing zone of the mounting wafer includes one portion that is immovable with respect to the body surface that the mounting wafer is secured to and another portion that is deflectable away from the body surface. The deflectable portion of the landing zone, also referred to as the floating landing zone, is sized for gripping between the fingers during pouch separation from the mounting wafer. Gripping of the floating landing zone during pouch separation helps isolate the pouch separation force from the abdominal area underlying the mounting wafer. The mounting wafer also includes indicia border lines that facilitate alignment of the pouch face plate with the mounting wafer.
