Abstract:
A system for providing a method of sealing skin with a film forming polymer is provided. The system includes providing an at least two part applicator containing a sealant composition in one or more frangible containers, providing instructions for using the applicator associated therewith, where the method including moving at least one of said applicator parts from a first position to a second position and applying said sealant to skin. The composition has film former, a plasticizer and 3000 to 10000 ppm of a dye that changes color when is undergoes a phase change. The color change is visible to a human eye under normal light conditions. changing dyes may be used to indicate that the composition has dried. The dyes change color in response to the phase change, i.e., drying of the film former. The dye may be added either directly to the composition, incorporated into a sponge on an applicator through which the composition is dispensed and applied, applied separately or applied simultaneously from a separate reservoir. The amount of dye in the composition can be adjusted to provide a visual cue to the user of the application area and the extent of cure though should generally be in the range of 3000 to 10000 ppm.
Abstract:
A synergistic antimicrobial composition containing at least two kinds of antimicrobial agents, including poly-hexamethylene biguanide (PHMB), stably associated to a material substrate is described. The substrate can take the forms of an anti-infection face mask, medical devices, or surgical instruments.
Abstract:
A skin sealant composition of a film former and a plasticizer and having various color changing dyes may be used to indicate that the composition has dried. The dyes change color in response to the phase change, i.e., drying of the film former.

Abstract:
Iodine is used in about 80 percent of surgeries in the US to remove some level of microbial load on the skin prior to making an incision. Skin sealants are applied over skin preps to seal the skin and hold any remaining bacteria in place. Iodine produces a characteristic orange-brown color on skin. A skin sealant is provided that has a decolorant that reacts with the iodine found in most skin preps, rendering the skin prep colorless. A skin sealant containing ascorbic acid (vitamin C), Indigo Carmine or Indigo will react with the iodine, thus visually indicating where the skin prep and sealant have been applied and allowing an unobstructed view of the incision.
Abstract:
Skin sealants are usually applied over skin preps to seal the skin and hold any remaining bacteria in place prior to surgical incisions. This sealant is generally left on the skin after surgery. This two step process is time consuming, as each layer must dry before the next one is applied. A skin preparation is provided that immobilizes at least 95 percent of bacteria on the skin and is essentially free of cyanoacrylate. The skin preparation has a fugitive solvent and may also have antimicrobial compounds like iodophors, biguanides, phenols, quaternary amines, antibiotics and metals. This skin preparation may be used without an additional skin sealant or incise applied over it prior to surgery.
Abstract:
A composition having various color changing tannates may be used to indicate that the composition has dried. The tannates change color in contact with an acid. The composition may be, for example, a skin prep, skin sealant, food product, paint or other building material or other product that undergoes a phase change. The tannate may be added either directly to the composition, incorporated into a sponge on an applicator through which the composition is dispensed and applied, applied separately or applied simultaneously from a separate reservoir. The amount of tannate in the composition can be adjusted to provide a visual cue to the user of the application area and the extent of cure.
Abstract:
A material substrate having at least part of a surface treated with an antimicrobial composition is described. The antimicrobial composition exhibits at least a 3 log 10 CFU reduction within a period of about 30 minutes after contact with various species of a broad spectrum of microorganisms. The substrate can be a nonwoven material that has good fluid barrier properties, which can be used in protective garments and sheets. Methods for manufacturing and imparting the antimicrobial treatment to the substrate are also provided.
Abstract:
La presente divulgación describe un tubo de cecostomía (30) que tiene un cabezal (36) con una abertura (42) y una válvula. Existe un catéter flexible (34) con un lumen (38) que tiene extremos proximal y distal, el extremo proximal del catéter está en comunicación fluida con la abertura en el cabezal, una porción del catéter se extiende lejos del cabezal para definir el extremo distal. Existe un dispositivo retenedor (32) que se proporciona en el extremo distal del catéter. El dispositivo retenedor puede cambiar de forma, de un primer perfil o configuración a un segundo perfil, por ejemplo en respuesta al contacto con un fluido, en donde el segundo perfil es más grande que el primer perfil y el segundo perfil se adapta para retener el tubo de cecostomía en su lugar, en un cuerpo. El dispositivo puede comprender un segundo lumen a través del cual se puede inyectar adhesivo y distribuirlo a lo largo de la superficie externa del catéter. El dispositivo puede colocarse en una sola operación quirúrgica inicial.
