WOUND DRESSING
20180344533 · 2018-12-06 ·

A would dressing includes an absorbent core including a top carrier layer and a bottom carrier layer, a superabsorbent substance dispersed between the top carrier layer and the bottom carrier layer and the bottom carrier layer, and a shell formed by a facing layer and a backing layer. The absorbent core is located in the shell between the facing layer and the backing layer. The facing layer and the backing layer each can include a supporting structure. The supporting structure of the facing layer and the supporting structure of the backing layer each can include an inner surface facing towards the absorbent core and an outer surface facing away from the absorbent core. The outer surface of the supporting structure of the facing layer and/or the outer surface of the supporting structure of the backing layer can be laminated with a foam layer.

Bandage for reducing blood leakage from aggressive bleeding site
10143594 · 2018-12-04 ·

A bandage for use at an aggressive bleeding site of a patient is disclosed. The bandage includes a stretchable wrap, an auxiliary strap, a primary absorbent body, and at plural secondary absorbent bodies. The primary absorbent body is located on the inner surface of the wrap. The wrap is arranged to be wrapped about and tightly encircle a portion of the body of a patient at which the bleeding site is located to cause the primary absorbent body to apply pressure thereto. The auxiliary strap is secured to the wrap and is normally held in stowed position on the wrap, but arranged to be moved to an extended position whereupon the secondary absorbent bodies overlies said primary absorbent body and apply pressure thereto and to the underlying aggressive bleeding site.

Pressure-Distributing Wound Prevention and Treatment Device

A dressing or device to distribute pressure for the purpose of prevention and treatment of wounds and intact skin is provided. The pressure distributing properties are achieved by a closed cell foam material that is in direct contact with the intact skin or wound and that can also have the ability to manage and absorb moisture. These unique characteristics creates a flexible, and easy to use dressing that can be cut to size and applied to any desired location on a patient.

SKIN-PROTECTIVE HYDROGEL WOUND DRESSING

Disclosed herein is a hydrogel wound dressing having a wound-contact side and a non-wound-contact side wherein the rate of moisture evaporation from said non-wound contact side is faster than the rate of moisture evaporation from said wound contact side, thereby causing said dressing to curl toward said non-wound contact side upon drying. Optionally, the hydrogel wound dressing can be comprised of two materials having different rates of moisture evaporation bonded together to form a bilayer structure.

Apparatus and method for wound infection prevention

A wound healing device and method that greatly reduces the risk of infection of an incision or wound by removing fluid from the subcutaneous skin layers. The wound healing device includes a first portion that is positioned external of, and on top of, the wound. At least one strip, cord, finger, member is in fluid communication at one end with the first portion while the second free end of the at least one strip, cord, finger, member is pushed down into the wound, in between the sutures or staples of a closed incision. Both the first portion and the at least one strip comprise fluid absorbable material for absorbing the wound fluid. The device remains in place for approximately 1-3 days after which it is removed. Upon removal, natural temporary type of fistulae are formed in the subcutaneous skin layers to continue draining wound fluids outward for another 1-2 days.

WOUND DRESSING AND METHOD OF TREATMENT

Embodiments disclosed herein are directed to negative pressure treatment systems and wound dressing systems, apparatuses, and methods that may be used for the treatment of wounds. In particular, some embodiments are directed to improved wound dressings comprising an obscuring layer that may hide fluid contained therein. Some embodiments may further comprise one or more viewing windows disposed therethrough so as to enable monitoring or examination of fluids contained therein.

Wound care materials, devices and uses

Material comprising a flexible porous hydrophilic polymer foam or fibre matrix comprising two matrix faces and therebetween a structural matrix framework defining a network of cells, having a cell network surface and therein a network of pores and a powder charge comprising antimicrobial additive and/or wound dressing additive, wherein the powder charge is comprised at the matrix face or faces and/or within the cell network or within the structural matrix framework and wherein the additive is micronized, a method for the preparation thereof comprising micronizing the additive and dosing powder charge to the matrix or a reactive phase for the manufacture of said matrix, devices comprising the material and uses thereof.

Oxygen distributor
10080850 · 2018-09-25 · ·

An oxygen distributor (1) positionable, in use, in a wound for supplying oxygen to the wound has an oxygen delivery area (17) for, in use, receiving a supply of oxygen. At least one tube (19A) extends from the oxygen delivery area, having a tube wall with an oxygen-permeable, liquid-impermeable section. Oxygen delivered to the oxygen delivery area can flow away from the oxygen delivery area along the, or each, tube.

Hybrid Dressings of Hydrophilic Material and Polymer Foam
20180263823 · 2018-09-20 ·

Disclosed are hybrid wound dressings that include at least one front layer of a hydrophilic absorbent material and at least one layer behind the front layer that is made of an open-celled polymeric foam made from high internal phase emulsions (HIPEs). The hydrophilic absorbent material may be a natural polymeric material; a synthetic, non-foam polymer; or a material like glass microfiber. Each layer has a rate of fluid absorption and a capillary suction pressure (CSP) for a working fluid like blood plasma. The CSP increases from the front layer toward the layers behind the front layer, such that fluid is drawn away from a wound.

HEMOSTATIC ABSORBENT PRODUCT FOR MUCOSAL MEMBRANES, KIT CONTAINIG THE SAME, AND METHOD OF USING THE SAME
20180256403 · 2018-09-13 ·

A kit that includes an absorbent product adapted for mucosal membrane hemostasis, and instructions using the absorbent product is disclosed. The absorbent product can include a liquid permeable pouch, and at least one sheet of absorbent material within the liquid permeable pouch. The instructions can include rolling and/or folding the absorbent product, placing the rolled and/or folded absorbent product proximate the site of the bleeding, and applying pressure to the absorbent product. The instructions can also include inserting the absorbent product into a mucous membrane, such as a nostril or the vaginal canal. Methods of utilizing the absorbent product and the kit are also disclosed.
