摘要:
The present disclosure provides amine-modified polymer foams, which may be used for wound dressing materials. For example, the modified materials can include a covalently attached molecule comprising free amine groups. Such amine groups can be used, for instance, to conjugate biologically active polypeptides and/or linkers. Methods for using modified polymers are also provided.
摘要:
The invention is a class of medical bandages that are effective for use in the treatment of various types of tissue burns, such as burns due to heat, chemicals, or sun exposure. The inventive bandages are comprised of a thin and flexible heat sink such as a hydrogel infused with a thermally conductive material such as aluminum oxide particles. The inventive bandages rapidly cool a burn wound by ensuring direct contact of the infused hydrogel with the burn to draw heat away from the burn via conduction.
摘要:
Disclosed is a wound dressing material comprising a substrate, about 2.5% to about 8% by weight of a bicarbonate, and a film-forming agent, the film-forming agent serving as a binder for said bicarbonate to said substrate, the film-forming agent and the bicarbonate being present in a ratio of between 1:2 and 2:1 with respect to one another. Also disclosed are a method for preparing a wound dressing material and a method for treating a wound.
摘要:
Absorbent product having a liquid permeable surface and a liquid impermeable opposite surface, the absorbent product including an odor control material, the odor control material including a carrier material and a plurality of odor control particles adhered to the carrier material. The carrier material has a first surface located towards the liquid permeable surface of the absorbent product and a second opposite surface located towards the liquid impermeable surface of the absorbent product. The plurality of odor control particles are bonded to the second surface of the carrier material with a water soluble binder substance wherein the binder substance at least partly dissolves when in contact with an aqueous solution.
摘要:
Provided is a water-absorbing agent which is less likely to cause gel blocking and is suitable for a sanitary product and an absorbent article each being thin and containing a large amount of a water-absorbing agent, and which, while maintaining or hardly losing the other physical properties (a fluid retention capacity and a bulk specific gravity) of the water-absorbing agent, simultaneously achieves a high water absorbing speed (e.g., FSR), a high fluid retention capacity under load, high liquid permeability, and salt tolerance. The water-absorbing agent is a polyacrylic acid (salt)-based water-absorbing agent whose surface and its vicinity are crosslinked by an organic surface crosslinking agent, characterized by satisfying the following (A)-(D): (A) Free Swell Rate (FSR) of at least 0.28 g/g/s, or Absorption Time (Vortex) of 42 seconds or less; (B) Absorption Against Pressure (AAP) of at least 20 g/g; (C) Salt Tolerance Index represented by “Salt Tolerance Index=(CRCdw)/(CRCs)” where CRCdw is a centrifuge retention capacity (unit; g/g) for deionized water (dw), and CRCs is a centrifuge retention capacity (unit; g/g) for a 0.9 weight % saline, satisfying “Salt Tolerance Index≦0.49×CRCs−7.47”; and (D) Bulk Specific Gravity of 0.55 to 0.70 g/cm3.
摘要:
Aptamer-modified polymers and materials thereof, used for binding factors in a wound bed. The aptamer-modified materials can be polypeptides conjugated to polymer foam materials and used, for example, as dressings, wound inserts, or pads.
摘要:
A wet wound dressing is formed from hydrophilic polyurethane foam. The hydrophilic polyurethane foam is formed by the foaming process using a hydrophilic polyurethane material and a foaming agent. The hydrophilic polyurethane material is star-shaped polyurethane formed by a reaction between a first polyether polyol and polyisocyanate then reacting with a second polyether polyol. The first polyether polyol includes at least three terminal hydroxyl groups. The hydrophilic polyurethane foam has non-continuous closed holes. The wet wound dressing possesses excellent permeability, water absorbency, and capable of preventing sticking of wound, thereby reducing frequency of changing wound dressing, such that wound healing is uninterrupted.
摘要:
An absorbent article, such as a catamenial device, comprises a liquid pervious topsheet, the topsheet having an inner surface oriented toward the interior of the absorbent article and an outer surface oriented toward the skin of the wearer when the absorbent article is being worn. The absorbent article includes a backsheet joined to the topsheet, the backsheet having an inner surface oriented toward the interior of the absorbent article and an outer surface oriented toward the garment of the wearer when the absorbent article is being worn. The absorbent article includes an absorbent core disposed between the topsheet and the backsheet, the absorbent core having an inner surface oriented toward the skin of the wearer when the absorbent article is being worn and an outer surface oriented toward the garment of the wearer when the absorbent article is being worn. The absorbent article includes a lotion composition applied to at least a portion of the inner surface of the topsheet, the inner surface of the backsheet, and/or a substrate or surface thereof disposed between the inner surface of the topsheet and the inner surface of the backsheet, wherein the lotion composition comprises a polypropylene glycol material.
摘要:
Disclosed are solid dressings for treated wounded tissue in mammalian patients, such as a human, comprising a haemostatic layer consisting essentially of fibrinogen and a fibrinogen activator, wherein the fibrinogen is present in an amount between 3.0 mg/cm2 of the wound facing surface of the dressing and 13.0 mg/cm2 of the wound facing surface of the dressing. Also disclosed are methods for treating wounded tissue.
