  • Skin coating with microbial indicator
    Publication number: 20080145316
    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. A skin coating is provided that has an indicator that gives a visible color change upon contact with microbes or microbial by-products and so provides an early warning of infection. The coating is a curable coating composition that may also be used without skin preps and may be used to protect other disruptions in the skin like wounds, bruises, abrasions, burns, acne, blisters, bites, stings, punctures and cuts. It may also be used to close wounds or provide an additional barrier to other parts of the skin, such as the nails and mucosa.

  • Color changing skin sealant
    Publication number: 20080063615
    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.

  • Thermochromic compositions for skin applicaion
    Publication number: 20080026015
    Abstract: Thermochromatic dyes may be added to compositions to be applied to skin in order to indicate where the composition is applied. After application to the skin the composition will turn from colored to colorless in a short period of time as its temperature rises in response to the curing reaction and to heat from the skin. The dyes are microencapsulated in order to avoid migration of the dye into the wound and to remain protected and functional. The dyes are selected such that they have a transition temperature between room temperature and that of the skin.

  • Detection of microbe contamination on elastomeric articles
    Patent number: 7300770
    Abstract: An elastomeric article that contains a chromogen that undergoes a detectable change in color in the presence of one or more microbes is provided. For example, in one embodiment, the chromogen is a solvatochromic dye (e.g., Reichardt's dye) that undergoes a color change in the presence of bacteria or other microbes. More specifically, such dyes may respond to differences in polarity between microbe components (e.g., cell membrane, cytoplasm, etc.) and the environment outside the cell. Alternatively, other mechanisms may be wholly or partially responsible for the interaction between the dye and the microbe, such as acid-base reactions, redox reactions, and so forth.

  • Solvatochromatic bacterial detection
    Patent number: 7282349
    Abstract: Solvatochromic dyes are used herein to indicate the presence of bacteria by incorporating them into various substrates such as films, woven and nonwoven fabrics, paper towels, coform and airlaid materials and bonded carded webs. These dyes change color in response to a change in polarity of the environment. Since water is a polar solvent and most bacteria are made from non-polar substances, the presence of bacteria changes the polarity of the environment, triggering a change visible by the unaided eye. A lateral flow device incorporating solvatochromic dyes and a method of detecting bacteria are also included.
