Multilayered gloves having enhanced barrier protection

Abstract

A type of multilayered glove consisting of an inner layer, an outer layer, and pigments between the layers is disclosed. The layers can be made of the same or different materials to incorporate desired barrier properties such as oil or chemical resistance to a glove. The layers can also be made of the same or different colors. The glove can have the same physical barrier protection as wearing two gloves, but without the discomfort of wearing two gloves. The glove enhances barrier protection and allows users to detect any breach of the outer layer during the surgical procedure, which enables the user to execute corrective actions before cross contamination occurs.

1 . A type of multilayered glove comprises of an outer layer, an inner layer, pigments embedded between the interface of the outer layer and the inner layer, and linkages between the inner and the outer layer.  
   
   
       2 . A glove according to  claim 1  wherein said inner layer and said outer layers have the same or different colors.  
   
   
       3 . A glove according to  claim 1  wherein said inner layer and said outer layers are made of the same or different type of latexes.  
   
   
       4 . A glove according to  claim 1  wherein the thickness of said inner layer is either thicker or thinner than said outer layer, and the thickness of said glove meets the ASTM D 3577 or ASTM D 3578 standard.  
   
   
       5 . A glove according to  claim 1  wherein said outer layer and said inner layer are physically linked together.  
   
   
       6 . A glove according to  claim 1  wherein the pigments embedded between said outer layer and said inner layer add the feature of providing a warning for the breach of the outer layer of said glove.

 a.Macrolex® Fluorescent Red G, Macrolex® Fluorescent Yellow 10GN, Macrolex® Green G Gran, Macrolex® Violet 3R Gran, Macrolex® Blue RR Gran, cadmium red, diarylide yellow, azoic yellow, chrome yellow, cadmium yellow, molybdate orange, pyrazolone orange, dianisidine orange, cadmium orange, pyrazolone red, azoic red, cadmium red, carbozole violet, perylene scarlet, quinacridones, carbaxole dioxazine, phthalocyanine, magenta, chrome oxide green, iron oxide, antimony oxide, sodium silicofluoride, titanium dioxide, clay, zinc oxide, zinc carbonate, calcium carbonate, silica, mica, animal black, charcoal, lampblack, litharge, lead chromate, white lead, lead carbonate, cadmium yellow, ultramarine, ferric ferrocyanide, vermilion (mercuric sulfide), chlorophyll (green), xanthophyll (yellow), carotene, anthocyanin, etc.    
   
   
       8 . A glove according to  claim 1  wherein said outer layer contains natural rubber, carboxylated acrylonitrile butadiene latex, nitrile rubber, polycholoroprene, polyurethane, polyisoprene, isobutylene-isoprene, ethylene-propylene, styrene-butadiene rubber, polybutadiene, polyvinyl alcohol, polyvinyacetate, silicone, acrylonitrile-butadiene, butyl rubber, silicone rubber, polyacrylate, and their blends, or mixtures thereof.  
   
   
       9 . A glove according to  claim 1  wherein said inner layer contains natural rubber, carboxylated acrylonitrile butadiene latex, nitrile rubber, polycholoroprene, polyurethane, polyisoprene, isobutylene-isoprene, ethylene-propylene, styrene-butadiene rubber, polybutadiene, polyvinyl alcohol, polyvinyacetate, silicone, acrylonitrile-butadiene, butyl rubber, silicone rubber, polyacrylate, and their blends, or mixtures thereof.  
   
   
       10 . A method for making a glove according to  claim 1  to form an impermeable film is not limited to a surgical or an examination glove but includes industrial gloves, balloons, condoms, finger cots, tubes or sheaths.  
   
   
       11 . A type of multilayered glove comprises of an outer layer, an inner layer, and linkages between the inner layer and the outer layer.  
   
   
       12 . A glove according to  claim 11  wherein said inner layer and said outer layers have the same or different colors.  
   
   
       13 . A glove according to  claim 11  wherein said inner layer and said outer layers are made of the same or different type of latexes.  
   
   
       14 . A glove according to  claim 11  wherein the thickness of said inner layer is either thicker or thinner than said outer layer, and the thickness of said glove meets the ASTM D3577 or ASTM D 3578 standard.  
   
   
       15 . A glove according to  claim 11  wherein said outer layer and said inner layer are physically linked together.  
   
   
       16 .
