Underpants-type disposable diaper with cover nonwoven fabric having improved air permeability
A cover nonwoven fabric covers a back surface of an inner member from between a front side outer member and the inner member to between a back side outer member and the inner member. The cover nonwoven fabric extends from a back surface side of a base portion of one side gather to a back surface side of a base portion of the other side gather. The cover nonwoven fabric has holes penetrating the front and back surfaces at intervals from between the front side outer and inner members to between the back side outer and inner members. The side edges of the cover nonwoven fabric are located at the positions same as the side edges of the narrowest part of the absorber in the width direction or on the center side in the width direction with respect to the side edges of the narrowest part.

Pressure-mitigating surfaces with inflatable chambers and methods for deploying and controlling the same
Described herein are systems and apparatuses for enhanced comfort through contact pressure reduction. In particular, the systems and apparatuses disclosed herein prevent or otherwise mitigate pressure by actively orienting a patient over an anatomy-specific pressure-mitigating contact surface on which the patient rests. A pressure-mitigating contact portion of the contact surface includes a plurality of independently pressurized chambers configured in a specific geometric pattern that is designed to mitigate contact pressure between a support surface (e.g., bed or chair) and a specific anatomic region of a patient's body when the specific anatomic region of the patient's body is oriented over an epicenter of the geometric pattern. Additionally, a plurality of elevated side support portions and a wedge interconnected on the base material are configured to actively orient the specific anatomic region of the patient's body over the epicenter of the geometric pattern.
