Abstract
A pouch for medical use (e.g., an ostomy pouch) is configured to facilitate flushing in a toilet. The pouch may carry an adhesive collar at its entrance aperture. The collar may have a thickness of 0.8 mm (about 32 mils) or less. The collar may include an adhesive layer of about 0.4 mm (about 16 mils) or less in thickness. The adhesive may be carried on a substrate of about 0.5 mm (about 20 mils) or less in thickness. The pouch may include a tear strip to facilitate tearing open of the pouch. The tear strip may be configured to generate a first initial tear from which propagate one or more other tears. Various features of the tear strip are described for enhanced functionality in use.
