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.

A dressing apparatus and methods for facilitating healing, the apparatus and methods involving a dressing member, an electromagnetically conductive element mechanically coupled with the dressing member, and a primary RFID device configured to transmit at least one output signal to the electromagnetically conductive element, to receive at least one return signal from the electromagnetically conductive element, and to provide an alert if the at least one return signal has a strength corresponding to at least approximately a threshold amount of fluid present in the dressing member, whereby healing is facilitated.

A first-aid device for controlling a bleeding injury of a limb, said first-aid device comprising, at least in use: an emergency bandage having a blood absorbing portion with a central point, configured for absorbing blood from the injury, and at least one bandage strap connected at least indirectly to the blood absorbing portion and configured for securely mounting the blood absorbing portion to the limb with said blood absorbing portion being positioned over the injury; and a tourniquet having a tourniquet longitudinal axis and attached to the emergency bandage so that, in a plan view of the device, said tourniquet longitudinal axis is spaced from said central point of the emergency bandage to a distance required for limiting blood flow to the injury, said tourniquet having at least one tourniquet strap extending along the tourniquet longitudinal axis and configured for securely mounting the tourniquet to the limb.

Provided herein are methods for making foam materials and foam material products having a polyurethane foam matrix defining a plurality of pores, a hydrophilic agent retained within at least a portion of the pores for improving an absorption of the foam material, a salt retained within at least a portion of the pores in an amount sufficient to render the foam material isotonic, a surfactant retained within at least a portion of the pores in an amount sufficient to be released upon contact with a moist surface. Also provided herein are methods for making a multilayer foam by casting a second foam layer on a first foam layer substrate and compressing the second foam layer before the second layer is fully cured to form an interface layer in situ.

The present invention is directed to a hemostatic textile, comprising: a material comprising a combination of glass fibers and one or more secondary fibers selected from the group consisting of silk fibers; ceramic fibers; raw or regenerated bamboo fibers; cotton fibers; rayon fibers; linen fibers; ramie fibers; jute fibers; sisal fibers; flax fibers; soybean fibers; corn fibers; hemp fibers; lyocel fibers; wool; lactide and/or glycolide polymers; lactide/glycolide copolymers; silicate fibers; polyimide fibers; feldspar fibers; zeolite fibers, zeolite-containing fibers, acetate fibers; and combinations thereof; the hemostatic textile capable of activating hemostatic systems in the body when applied to a wound. Additional cofactors such as thrombin and hemostatic agents such as RL platelets, RL blood cells; fibrin, fibrinogen, and combinations thereof may also be incorporated into the textile. The invention is also directed to methods of producing the textile, and methods of using the textile to stop bleeding.

This disclosure relates to a multi-layer wound care device having absorption and fluid transfer properties. The wound care device contains capillary force one-way pumps that are capable of transporting fluid, such as wound exudate, away from a wound site to the opposite side of the wound care device, which functions as a segregated fluid reservoir. This fluid transport mechanism generally aids in reducing wound maceration by removing excess wound fluid and the protease enzymes and infectious bacteria contained within the wound fluid. The wound care device performs this function, often times for multiple days, without the loss of the physical integrity of the wound care device. In addition to providing a uni-directional fluid transport mechanism, the wound care device provides improved absorption properties.

A device designed to be packed into a wound that will expand to fill the voids of the wound to control bleeding is provided. The device is comprised of two or more individual pouches, linked together, and filled with an expandable material that will swell upon absorption of blood through the pouch walls.

According to some aspects of the invention a method for creation of a wound covering with haemostatic action includes: applying to an open wound a cell structure (grid)-forming water-soluble haemostatic composition designated as a Hemoblok consisting of a polyacrylic matrix as an active ingredient, where the matrix includes one or more polymeric carboxylic acid of a predetermined average molecular weight range, and a bactericidal agent; creating by Hemoblok on a wound surface a structure clot formation with blood plasma proteins, including albumin; creating by Hemoblok on the wound, a covering containing albumin molecules in cells of a polyacrylic structure matrix (grid), which is a primary organizer of sustainable grid structure clot film; further supplying of Hemoblok on an open wound surface to form a multilayered solid grid structure film; terminating of Hemoblok supply on a wound surface with following gradual replacement of a surface structure hemoblok-protein by fibrin.

In some embodiments, a system includes an applicator pad, an application device (e.g., a grip), and a reservoir. The grip can be releasably couplable to the applicator pad and configured to dispose the applicator pad against a wound of a subject such that pressure can be transferred to the wound via the applicator pad to enhance hemostasis. The reservoir can be configured to contain medication to be released to the wound via the applicator pad.

A wound dressing is provided, which includes a substrate and a plurality of silver particles. The substrate has a first surface and a second surface which are opposite to each other, and the substrate further includes a plurality of microstructures. A plurality of silver particles is embedded rather in the microstructures or in the gaps between the microstructures, between first surface and the second surface. The wound dressing has a moisture vapor transmission rate being about 4000-20000 g/(m.sup.2*24 hr).
