A pressurized tourniquet includes an elastic band, a hemostatic dressing, and a pressurized member. A through tough is formed at the outer surface of the elastic band and has an extending direction vertical to the longitudinal direction of the elastic band and parallel to the width direction of the elastic band. The hemostatic dressing is disposed to the inner surface of the elastic band. The pressurized member has a base portion, an insertion portion connected with the base portion and detachably inserted in the through tough and having one end forming an anchor portion protruding from and interfered with the through tough, and a pressurized portion connected with the base portion and parallel to the insertion portion to form a slot therebetween for passage of the elastic band. Thus, the pressurized tourniquet of the present invention has advantages of convenient manufacturing and easy replacement of accessories.

The present disclosure provides a wound dressing composition comprising cross-linked hydrogel scaffold and embedded therein anti-bacterially active honey, said activity being determined by the detection of hydrogen peroxide production rate by said wound dressing; said wound dressing further comprising at least one of a photo-initiator and/or at least one UV cross linker, the total amount of said photo-initiator and/or UV cross linker is equal or less than 0.2% w/w out of the total weight of the wound dressing. Also disclosed herein is a method of preparing the wound dressing and methods of using the same with respect to wounds, the method of preparation comprises mixing a hydrogel forming mixture comprising hydrogel forming monomer or monomers, honey and at least one photo-initiator and/or at least one UV cross-liker to form a homogenous mixture; and subjecting the homogenous mixture to UV irradiation until said homogenous mixture solidifies.

The present invention is in the fields of mechanical engineering and medicine, focused on the area of dressings and devices for negative pressure therapies. More specifically, the invention discloses an improved dressing, a device that provides the generation and indication of negative pressure that can be detachably connected to a dressing, a kit, a manufacturing process and a negative pressure therapy. The dressing of the invention comprises a valved connector detachably connectable to a device for manual generation of negative pressure and optionally comprises a means for colorimetric indication of negative pressure. The device of the invention provides manual generation of negative pressure and also visually indicates the negative pressure, for the user to verify that the negative pressure is within a range suitable for treatment, which preferably includes alternating the intensity of the negative pressure. The invention provides several practical advantages, including: the generation and indication of negative pressure in a simplified manner; the reduction of costs when compared with the costs of electronic devices for indicating negative pressure; the expansion of access to patients to the benefits of negative pressure therapy; use in non-hospital conditions.

A tubeless energy drainage device for trauma, pertaining to the field of tubeless drainage technology, especially relating to a tubeless energy drainage device for trauma. The device includes energy transmission carriers, lead wires, and a frequency electrical energy generator. The frequency energy resonance generator transmits electrical energy to the energy transmission carriers, activates metal potassium ions on the energy transmission carriers, and creates resonance through conduction of metal ions in a wound covering layer and changing frequency of a wound, thereby achieving retrograde drainage of the wound's own sinus in a drainage area. The device disclosed by the present invention is of great significance for the rapid and full drainage of intractable wounds and battlefield wounds, and the drainage, healing, and pain relief of minute wound fistulas that cannot be tubed.

A cover layer for a vacuum wound therapy dressing includes a backing layer formed from a flexible polymeric membrane and an adhesive layer for affixing the backing layer over a wound bed to provide a substantially fluid-tight seal around a perimeter of the wound bed. The cover layer is reinforced with a reinforcement layer extending to a peripheral region of the backing layer to distribute forces associated with evacuating a reservoir, as defined by or within the cover, to stimulate healing of the wound bed.

This disclosure relates to apparatuses and methods for preventing the onset and progression of post-operative ileus and for preventing and/or alleviating post-operative edema. In one example, a fan-like polyurethane heat-sealed bilayer that surrounds a plurality of wedge-shaped foam strips that join at a collecting foam portion, is subjected to a negative pressure provided through silicone tubing which is sealed to the perforated collecting foam portion. Such negative pressure applied for approximately 48-72 hours after closure of the abdomen, helps prevent and/or alleviate post-operative edema and ileus, which in turn enhances patient recovery, and reduces the length of their hospital stay.

A dressing for treating tissue may be a composite of dressing layers, including a contact layer, a manifold layer, and an adhesive drape. The manifold layer may include one or more layers of felted open-cell foam in some examples. The manifold layer may be relatively thin to reduce the dressing profile and increase flexibility, which can enable it to conform to difficult geometry and other tissue sites under negative pressure. The dressing may have a length and a width less than the length. The manifold layer may include a population of holes extending at least partially therethrough, wherein the holes may be configured to promote anisotropic contraction of the dressing parallel to its width. The population of holes may have a circular, ovoid, triangular, square, hexagonal, irregular, or morphous shape. The dressing may be a bolster that may anisotropically contract to provide a closing force to a linear wound.

Systems, apparatuses, and methods for closing an opening through a surface of a tissue site are described. The system includes a sealing member adapted to cover the opening to form a sealed space and a negative-pressure source adapted to be fluidly coupled to the sealed space to provide negative pressure to the sealed space. The system also includes a contracting layer adapted to be positioned adjacent the opening and formed from a material having a firmness factor and a plurality of holes extending through the contracting layer to form a void space. The holes have a perforation shape factor and a strut angle causing the plurality of holes to collapse in a direction substantially perpendicular to the opening. The contracting layer generates a closing force substantially parallel to the surface of the tissue site to close the opening in response to application of the negative pressure.

The present invention includes disposable absorbent articles, such as disposable undergarment, diapers, other garments, and wound care dressings, having an elastomeric material disposed between two substrate layers and an absorbent core system that disposed on top of or between the two substrate layers. This invention may also include a disposable article having an elastomeric material disposed between two substrate layers without an absorbent core. The inclusion of an stretch adhesive in the construction of the article in various portions of the article (e.g., fastening tabs, front and/or rear sections, entire article, etc.) results in improved securement of the article to a wearer for reducing the risk of leakage and further improving comfort for the wearer. Furthermore, the inclusion of a stretch adhesive can provide a smooth contoured fit to a wearer, thereby improving appearance and self-confidence for the wearer.
