Hemostatic agents and devices are made from oxidized cellulose fiber, the oxidized cellulose having a carboxylation content increased by the action of nitrogen dioxide on virgin cellulose fiber. A composition may be incorporated into the oxidized cellulose fiber to cause a pharmacological effect on a wound to which the hemostatic agents and devices are applied. When applied, the oxidized cellulose fiber causes blood emanating from the wound to clot. The oxidized cellulose fiber can either be resorbed into the wound or removed from the wound after healing. A hemostatic bandage includes a pad of unwoven oxidized cellulose fibers mounted on a substrate. Methods of arresting a flow of blood emanating from a wound using such devices are also disclosed. Methods of fabricating oxidized cellulose are also disclosed.

A device includes a patch or bandage, applied on or adjacent to a specific external surface of a human or animal body part, which delivers light of varying wavelengths, intensity and duration for treatment of various diseases or abnormalities.

Compositions that include nanoscale structured materials or precursors thereof (e.g., self-assembling peptides) are described. The compositions can include other substances (e.g., a vasoconstrictor). Also described are methods for using the compositions to promote hemostasis, to protect the skin or wounds from contamination, to decontaminate a site upon removal of previously applied compositions that provided a protective coating, and to inhibit the movement of bodily substances other than blood. The compositions are also useful in isolating tissue, removing tissue, preserving tissue (for, e.g., subsequent transplantation or reattachment), and as bulking, stabilizing or hydrating agents. Medical devices that include the compositions (e.g., a stent or catheter), bandages or other wound dressings, sutures, and kits that include the compositions are also described.

Disclosed herein are color change laminate materials suitable for a variety of uses. The color change laminate materials include at least two layers of extensible materials having visually distinct coloration, and indicate a stretched or extended state by exposing the previously covered coloration of a lower layer. The color change laminate materials may also indicate the amount of stretching or extension is applied to the laminate. When the laminate includes elastic materials capable of stretch and recovery, the color change laminate materials may further be reversible color change laminate materials that can display color change upon extension and then recover the extension and return to the original coloration. Such color change laminate materials and reversible color change laminate materials are highly useful for use in garments or other textile type applications, in or on personal care products, protective wear products, health care and medical care products, bandages and the like.

Disclosed herein are elastic laminate materials having an elastic member and at least one fibrous nonwoven web. The elastic laminate materials have highly desirably properties of extensibility and elastic recovery, and cloth-like aesthetic properties of softness and drapability. In embodiments, the elastic laminate materials may include a second fibrous nonwoven web bonded to the opposite side of the elastic member. Also disclosed herein is a process for forming the elastic laminate materials. Such elastic laminate materials are highly useful for components in or on personal care products, protective wear garments, medical care products, bandages and the like.

The invention relates to a therapeutic device to promote the healing of a wound, comprising a porous paid which is permeable for fluids to place on the wound, a bandage to cover the wound and to provide an essentially airtight seal around the wound, a drainage line connecting the pad with a suction pump so that suction can be applied to the wound to draw the fluids away from it, whereby the line is connected to the suction pump via a canister to collect fluid sucked from the wound, a connector to connect the pad to the drainage line, means to determine a prevailing wound pressure basically comprising the wound and this surrounding skin area, as well as a control unit to control the wound pressure. In order to generally improve metrology with the goal of making possible a more reliable and more secure dressing of the wound, and also to design metrology in an especially simple and error-free way, it is proposed that the pad interconnect the suction pump solely via the drainage line.

An apertured fibrous nonwoven web with an array of apertures is made that allows for increased functionality and improved aesthetic appearance. The material is particularly well-suited for use as a topsheet or bodyside liner material for personal care absorbent articles including, but not limited to feminine hygiene products, diapers, diaper pants, training pants, adult incontinence devices, bandages and the like. The fibrous nonwoven web includes first, second and third arrays of apertures with varying characteristics that provide improved fluid handling properties for various body exudates.

A surgical bandage for treating a wound that allows various fluids or fluid-like substances including cyanoacrylate adhesives to be applied. The surgical bandage has a wound treatment portion for being placed over a wound and a place for a flowable cyanoacrylate adhesive or any other fluid or fluid-like substance to be applied to the underlying wound (laceration, surgical incision or other tissue separation). A source is used to apply the cyanoacrylate or other fluid to the wound treatment portion flowing through at least one opening of the wound treatment portion to the underlying wound and its surrounding area either by direct application or from a non-contact distance. The surgical bandage allows for direct visualization before, during and after its application. The surgical bandage allows for removal of blood or any fluid that may be present in, on or around the wound by blotting or wiping.

A modified starch material for biocompatible hemostasis, biocompatible adhesion prevention, tissue healing promotion, absorbable surgical wound sealing and tissue bonding, when applied as a biocompatible modified starch to the tissue of animals. The modified starch material produces hemostasis, reduces bleeding of the wound, extravasation of blood and tissue exudation, preserves the wound surface or the wound in relative wetness or dryness, inhibits the growth of bacteria and inflammatory response, minimizes tissue inflammation, and relieves patient pain. Any excess modified starch not involved in hemostatic activity is readily dissolved and rinsed away through saline irrigation during operation. After treatment of surgical wounds, combat wounds, trauma and emergency wounds, the modified starch hemostatic material is rapidly absorbed by the body without the complications associated with gauze and bandage removal.

The composition and method for healing tissues is a medicinal composition for facilitating the growth, protection and healing of tissues and cells in animals and humans.

The main ingredient of the formulated compositions is hydrolyzed collagen, which can be combined with polysulfated glycosaminoglycans, hyaluronic acid or salts thereof, or a glucosamine salt, and mixtures thereof. The composition may be formulated as an aqueous eye drop solution.

A sleeve for covering a portion of a limb at a wound site incorporates a molecular sieve material which is at least partially exposed so that blood flowing from a wound site over which the sleeve is positioned contacts the molecular sieve material to facilitate clotting. One end of the sleeve may be closed to form a stocking or a mitten. The molecular sieve material may also be incorporated into a cap or similar device for wearing on the head of a victim. A chin strap may be attached to the cap to facilitate the retaining of the cap on the victim's head. The molecular sieve material may also be incorporated into a bandage that is directly wearable on a wound.
