  • Patent number: 8323266
    Abstract: A fluid delivery device for transdermal delivery of a fluid to a patient. The device comprises an envelope that may be applied to a patient's skin. The envelope comprises at least one diffusion layer coupled to at least one impermeable layer such that at least a chamber is defined therebetween. Other embodiments include internal diffusion layers, and thus possess additional chambers, as well. In one arrangement, an adhesive boundary layer permits the device to be removably secured to a patient and inhibits radial migration of fluid beyond the periphery of the device. In another arrangement, preferably, an anti-microbial layer is provided to inhibit the growth of microorganisms.
    Type: Grant

  • Patent number: 7854732
    Abstract: A fluid delivery device is provided for transdermal delivery of fluid medications to patients. The device can comprise a thin envelope which is applied to a patient's skin. The envelope can comprise at least one diffusion layer coupled to at least one impermeable layer such that at least one chamber can exist therebetween. Other embodiments can include internal diffusion layers, and thus can possess additional chambers, as well. The impermeable layer can comprise a top surface of the device. A valve positioned in the impermeable layer can facilitate filling the device with fluid, as well as connection of the device to external fluid sources such as an intravenous bag, pump, or other external fluid delivery system. The diffusion layer can comprise a coiled wire member to control the rate of fluid flow from the device to the patient's skin.
