摘要:
The inventive disclosure contained herein is generally directed to a class of medical bandages that in many embodiments are effective in the treatment of various types of tissue burns, whether be burns due to thermal burns, sun exposure, or rashes. Such products can include a plurality of specialized bandages and wraps that incorporate an extremely thin layer of thermally conductive metal (often aluminum) at the base of a substrate adapted to be in direct contact with a burn wound, while manufacturing the top side of the aluminum substrate to have a heat-dissipation-enhancing topography to help cool burns faster by enhancing thermal-convection properties. The bandage can also feature a thermochromic indicator for users to realize the thermal-cooling status of a burn to which a bandage has been applied.
摘要:
Active polymeric films are described which comprise a permeable polymer matrix provided with one or more functional groups and, embedded within the polymer matrix, one or more nanoparticles of an inorganic substance(s) such as copper or silver to provide antibacterial properties.
摘要:
An adhesive patch for attaching to the skin for medical, cosmetic, and/or orthopedic purposes. The patch is formed with a film that includes a carrier material, which is provided with a therapeutically effective coating on both sides.
摘要:
A wound contact device comprising a permeable material and a wound contact layer having voids extending through the contact layer to a depth in the permeable material. The wound contact layer can comprise a thin sheet or film forming a generally flat and smooth wound contact surface having essentially no discontinuities or gaps. The wound contact layer can comprise a thin sheet of highly calendered fabric forming a wound contact surface having a mean surface roughness in the range of about 0 microns to about 200 microns. In progressive wound healing, an embodiment of the wound contact device having the fabric contact surface is used in earlier healing stages and an embodiment of the wound contact device with film contact surface is used in later healing stages. The wound contact device is particularly useful in wound dressings for use in suction-assisted wound therapy.
摘要:
An antibacterial bandage formed from at least one foam with at least one antimicrobial agent and at least one hemostatic agent is disclosed. The at least one antimicrobial agent and the at least one hemostatic agent may be mixed with materials forming the foam during manufacture of the at least one foam.
摘要:
Silver nanoparticles are mixed with a chitosan solution, to form a chitosan/silver nanoparticle dispersion, which is then subjected to a freeze-drying process, to form a chitosan/silver nanoparticle matrix suitable for use as a wound dressing.
摘要:
A hemostatic biocidal dressing includes pro-coagulant and biocidal agents providing a physical barrier to bleeding as well as chemical action to promote blood coagulation and thereby arrest coverage. At the same time, biocidal properties of the dressing prevent the introduction of infected agents and the establishment of infection within wounded tissue. A silverized textile provides biocidal action while a granulated hemostatic agent disposed within interstitial regions between polymer fibers provides coagulating action.

摘要:
A hemostatic agent comprises diatomaceous earth in particle form. Devices for promoting hemostasis comprise diatomaceous earth in particle form and a receptacle for retaining the particles therein. The receptacle is defined by a mesh having openings therein. A hemostatic sponge comprises a substrate, diatomaceous earth disposed on the substrate, and a release agent disposed on the substrate. A hemostatic sponge may also comprise a film into which diatomaceous earth is incorporated, or it may comprise a substrate, diatomaceous earth disposed on the substrate, and a film disposed over the diatomaceous earth. A hemostatic sponge may also comprise a first substrate, diatomaceous earth disposed on the first substrate, and a second substrate disposed on the diatomaceous earth. When treating a bleeding wound using any of the foregoing devices, application of the device causes the diatomaceous earth to come into contact with blood to cause a clotting effect.
摘要:
An apparatus includes a pressure housing configured to be coupled to a vacuum source and a diaphragm sealingly coupled to the pressure housing. The diaphragm is configured to move in response to the vacuum source. A magnet is coupled to the diaphragm. A magnetic switch is disposed opposite the magnet and is configured to be actuated by the magnet when the magnet is a predetermined distance from the magnetic switch. The magnetic switch is configured to selectively actuate the vacuum source.
