A disposable dressing forms a compartment around and above a wound site and a volatile antimicrobial compound is allowed to sublimate/evaporate into the compartment. A heating element is included in the dressing, with heat stimulating wound healing and simultaneously accelerating sublimation/evaporation of the antimicrobial compound.

Method for Wound Infection Prevention
20230083446 · 2023-03-16 ·

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 upward for another 1-2 days.

Advanced Wound Dressing For Incisional Wounds That Provides Apposition Forces As A Result Of Fluid Absorption
20220331166 · 2022-10-20 ·

A dressing for the treatment of incisional wounds includes an upper cover, a patient interface layer, and an absorbent material. The upper cover is configured to substantially cover the incisional wound. The upper cover includes a drape and a plurality of spines coupled to the drape. The drape includes a first side and a second, wound-facing side. The patient interface layer is coupled to the second side of the drape and includes a plurality of openings that are configured to receive fluid from the incisional wound. The absorbent material is disposed between the second side of the drape and the patient interface layer.

Ph sensing for sensor enabled negative pressure wound monitoring and therapy apparatuses

Embodiments of apparatuses, systems, methods for monitoring wound pH are disclosed. In some embodiments, a wound dressing includes one or more optical sensors configured to measure a change in color of a pH-sensitive adhesive that changes color in response to changes in wound exudate pH. In some embodiments, the wound dressing may further comprise hydrophilic channels that direct wound exudate to a pH-sensitive material over the optical sensors. Such dressings may also be used in combination with a negative pressure wound therapy system.

MEDICAL DRESSING

A medical dressing having a geometrical plane of symmetry. A border portion extends along the contour of the pad. A central portion of the dressing has a smaller width perpendicular to the plane of symmetry than the widths of the adjoining portions. The medical dressing comprises a gripping tab which is coplanar with the border portion and which projects outwardly from the border portion. The medical dressing may be used for pressure ulcer prevention, such as at a heel of a human body.

Therapy delivery systems and methods

Fluid removal systems and methods for removing a fluid from a tissue site are presented. The systems include a semi-permeable inbound conduit, which is fluidly coupled to a treatment-fluid delivery unit, for placement proximate to the tissue site, and a semi-permeable outbound conduit, which is fluidly coupled to the inbound conduit and to a treatment-fluid collector, for placement proximate to the tissue site of a patient. The treatment-fluid collector receives a treatment fluid and a recruited fluid from the tissue site. A recruited-fluid determination unit may be coupled to the treatment-fluid collector to determine a volume of the recruited fluid recruited from the patient. The treatment fluid is any fluid (including a gas) that pulls the fluid from an interstitial and intracellular space. A reduced-pressure treatment subsystem may also be included, among other things, for removing ascites and other fluids from a body cavity.

ABSORBENT WOUND DRESSING

The present invention concerns extensible absorbent wound dressings. The wound dressing has a wound contact layer having a proximal surface facing toward the wound and a distal surface facing away from the wound, and a backing layer having a proximal surface facing toward the wound and a distal surface facing away from the wound, the backing layer having an absorbent region located on a proximal surface thereof, the absorbent region comprising a plurality of discrete absorbent members, wherein the backing layer is configured to be positioned over the wound contact layer, such that the absorbent region is located adjacent to the distal surface of the wound contact layer, and wherein the absorbent region and the wound contact layer are configured to be detached at least in an area inside a perimeter of the absorbent region. The absorbent wound dressings of the present invention can be used to dress so-called truly three-dimensional anatomical areas, such as for example a knee or an elbow.

Wound dressing, ingredient delivery device and IV hold-down, and method relating to same

An adhesive device used as a wound dressing, ingredient delivery device or IV hold-down in which inadvertent edge release of these devices along the periphery of the polymeric film layer is minimized when the handling layer, which is adhered to the polymeric film layer, is removed after application of the polymeric film layer to the patient.

Wound dressing and method of treatment

A wound dressing, a method of manufacturing a wound dressing, and a method of treating a patient are disclosed. The wound dressing may include an absorbent layer for absorbing wound exudate; and an obscuring element for at least partially obscuring a view of wound exudate absorbed by the absorbent layer in use.

Wound and bandage protection system and method
09833361 · 2017-12-05 ·

A wound/bandage protector configured as a wrap, a sock/mitten, or a bandage may be made out of stretchable material. The wrap may have one or more fastening straps as well as possibly a first catch fastening surface. The sock/mitten may have a fastening strap and a sheath. The wrap, the sock/mitten, and the bandages may have apertures and aperture covers. In addition, the wound/bandage protectors as well as the bandages may have diamond or triangular gauze configurations with the gauze pad having three or four primary corners, the primary corners of the gauze pad in most instances being oriented towards edges of the body portion or length or width tangents of the body portion, preferably mid-points or mid-sections of the length or width tangents or body portion edges.
