The hydrogel is preferably a hydrophilic material such as a polyurethane, collagen, polyacrylonitrile, polyvinyl alcohol, or polyvinyl acetal. The fire retardant fabric is preferably a fabric woven or knitted from polyamide or polyimide fibers having a thickness sufficient to provide the desired degree of protection. The composite is applied to the object to be protected, which can be a person or an endotracheal tube or surgical instrument, using the adhesive to adhere the composite thereto.

  • Patent number: 5002540
    Abstract: A device for inserting into the vagina of a patient for delivery of a medicament in the vagina. The walls of the tubular member comprising the device are comprised of water-swellable materials having a higher porosity at one end than the other, the relatively low porosity end being positioned distally in the vagina to the relatively high porosity end. The medicament is contained within a reservoir in the tubular member and delivered to the vagina through the pores in the walls of the tubular member at different rates depending upon the porosity. Also provided is a method of delivering a medicament to the vagina of a patient.
