Class Information
Number: 604/378
Name: Surgery > Means and methods for collecting body fluids or waste material (e.g., receptacles, etc.) > Absorbent pad for external or internal application and supports therefor (e.g., catamenial devices, diapers, etc.) > Containing layers having differing absorption characteristics (e.g., flow control, wicking, etc.)
Description: Subject matter wherein significance is attributed to a layer or the collecting means which is characterized by specific structure or composition which, by the nature of the material provides capillary action and allows the movement of the absorbed body liquids from one component of the collecting means or the movement of the absorbed body liquids from one portion of the component to another portion thereof in order to maintain that portion of the collecting means next to the body or body orifice as dry as possible.
