Patent number: 12168843Abstract: A nonwoven web material is formed from fibers including a first polymer, a second polymer and a filler. The first polymer and second polymer may be olefin homopolymers and the filler may be calcium carbonate. The second polymer may have a lower melt flow rate than the first polymer. The fibers are formed in a monocomponent, i.e., monofilament, or multicomponent, e.g., sheath-core bicomponent, arrangement. The nonwoven web material may be used to form an article such as a medical product, a surgical product, a personal protective product, and/or an industrial garment.Type: GrantFiled: December 21, 2020Date of Patent: December 17, 2024Assignee: O&M Halyard, Inc.Inventors: Prasad S.

Patent number: 11666107Abstract: A protective guard is provided for sealing an interface. The protective guard includes a body having a fluid impervious material and proximal and distal segments that may comprise a superabsorbent or a non-superabsorbent material. The proximal and distal segments are positioned on first and second sides, respectively, of the interface. The protective guard extends about the interface to create a fluid barrier. In some embodiments, the non-superabsorbent material may be an elastic material, such as an elastic band, and in particular embodiments, the non-superabsorbent material may be nitrile. In further embodiments, the non-superabsorbent material may be an expandable material that expands upon contact or interaction with a fluid.Type: GrantFiled: April 17, 2020Date of Patent: June 6, 2023Assignee: O&M Halyard, Inc.Inventors: Prasad S.

Patent number: 11528947Abstract: A personal protection and ventilation system is provided. The system includes a gown having front and rear panels, a hood, and visor; a fan; an air tube; and a helmet. The fan is positioned between the wearer and a body-facing surface of the rear panel. The front panel and at least a portion of the hood are formed from a first material including a first spunbond layer, a spunbond-meltblown-spunbond laminate, and a liquid impervious elastic film disposed therebetween. The first material has an air volumetric flow rate of less than about 1 standard cubic feet per minute (scfm). The rear panel is formed from a second material including a nonwoven laminate having an air volumetric flow rate of about 20 scfm to about 80 scfm. Therefore, the fan is able to intake a sufficient amount of air from the environment through the rear panel to provide cooling/ventilation to the hood.Type: GrantFiled: August 23, 2019Date of Patent: December 20, 2022Assignee: O&M Halyard, Inc.Inventors: Jerald T.

Patent number: 10314346Abstract: A multi-layered face mask coated with discontinuous patterns of phase change material are incorporated into the face mask construction to provide for cooling of the microclimate in the dead space of the face mask. Optimized cooling is achieved by strategic placement of layers coated with a phase change material within the mask construction and the amount and density of the phase change material in contact with the temperature sensitive areas of the face, as well as areas experiencing the maximum amount of flux from exhaled breath. The shape of the mask can also be adjusted to increase skin contact with the phase change material and decrease dead space volume, which reduces the volume of warm exhaled air and can provide sufficient cooling with less phase change material. The discontinuous patterns of phase change material also provide inter-layer spacing between the layers of the mask, which can improve splash resistance.Type: GrantFiled: April 20, 2017Date of Patent: June 11, 2019Assignee: O&M Halyard, Inc.Inventors: Prasad S.
