Step 1: Wipe the stoma and its surrounding skin with warm water and dry, remove the sclerotic keratinized skin and stain, and keep the skin around the stoma clean and dry.

Step 2: Measure the stoma’s size with the measuring card supplied. Please do not touch the stoma with your fingers while measuring it.

Step 3: According to the measured size and shape of the stoma, cut a hole of an appropriate size on the film of the ostomy flange. The hole diameter is usually 2mm bigger than the stoma diameter.

Step 4: Peel the protective release paper on the inside ring of the flange and stick aiming at the stoma(It is good to blow air into the bag before attaching, to prevent thin films from sticking to each other), and then strip the protective release paper on the outside ring， and carefully paste-up from the middle towards the outside.

Step 5: To make stickup secure(especially in areas and seasons with low temperature), you should press the pasted part with your hands for several minutes, in turn, the hydrocolloid flange could increase viscosity with the rising temperature.
