Apparatus for aspirating, irrigating and cleansing wounds

An apparatus for cleansing wounds in which irrigant fluid from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a device for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing. The cleansing means (which may be a single-phase, e.g. microfiltration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The dressing and a method of treatment using the apparatus.

Method and apparatus for making patterned apertured substrates
11484446 · 2022-11-01 · ·

The present disclosure relates to apparatuses and methods for making patterned apertured substrates that may be used as components of absorbent articles. During the manufacturing processes, a precursor substrate advances in a machine direction between a pattern roll and an anvil roll. The pattern roll rotates about an axis of rotation and includes a plurality of pattern surfaces, wherein the substrate is compressed between the anvil roll and the pattern surfaces of the pattern roll to form discrete bond regions in the substrate. The pattern surfaces on the pattern roll are formed on continuous threads extending circumferentially around the axis of rotation along helical paths parallel with each other. As such, the pattern surfaces press the substrate against the outer circumferential surface of the anvil roll in the different axial locations along the cross direction as the pattern roll rotates when forming the discrete bond regions.

Absorbent core layer and absorbent personal care article containing such layer
11253407 · 2022-02-22 ·

An absorbent core layer (18) for absorbing and retaining body exudate includes a first longitudinally directed end region (25), a second opposing longitudinally directed end region (26), and a middle region (22) positioned between the end regions. The middle region (22) includes a first embossing pattern and has a first thickness. The first longitudinally directed end region (25) and second opposing longitudinally directed end region (26) each include a second embossing pattern different from the first embossing pattern, and also having apertures. The end regions (25, 26) each have a second thickness, the second thickness being less than the first thickness.
