Pre-expanded tampon pledget

Abstract

The present invention provides a pre-expanded tampon pledget formed from cellulosic absorbent fibers. The fibers are not tightly compressed, thus, the pledget has a reduced fiber density. As a result, a softer, more pliable pledget is formed that not only increases user comfort during use, but also affords a user with comparable and / or increased leakage protection over conventional tampons or tampon pledgets.

Description

technical field [0001] The present invention generally relates to an improved tampon or swab. More particularly, the present invention relates to a pre-expanded hemostatic swab. The pre-expanded hemostatic swab has reduced fiber density and provides comparable or improved leak protection and performance compared to similar commercially available compressed hemostatic swabs. Background technique [0002] Hemostatic swabs are typically compressed either during processing or prior to placement in the hemostatic applicator. These swabs typically compress their fibers to allow for easy ejection of the swab from the applicator and, more importantly, easy insertion of the swab into the vagina. In such a hemostatic swab, the fibers of the swab swell significantly when they come into contact with moisture. Once inflated, the hemostatic swab will eventually conform to the contours of the body to provide leak protection. Typically, for better leakage protection, more fibers are inc...

Problems solved by technology

[0004] Until now, the benefit of providing a hemostatic swab with a lower density and thus fewer fibers per unit volume has not been appreciated

Additionally, it has not been appreciated that lower density or fewer fibers per unit volume achieve comparable and / or improved leakage protection relative to common hemostatic swabs
