  • Publication number: 20140154786
    Abstract: Exothermic and/or endothermic chemical reactions in combination with phase change materials can produce output temperature(s) within strict tolerances without requiring expensive and complicated external equipment to generate and maintain an output temperature. Similarly, an exothermic phase change material, which generates heat as a consequence of crystallizing a supercooled liquid, can generate heat at a constant temperature, without requiring expensive and complicated external equipment, as a consequence of the liquid form of the exothermic phase change material being in equilibrium with the solid form of the exothermic phase change material. Numerous biological and chemical processes and/or diagnostic devices require a constant temperature or temperatures for set periods of time.

  • Patent number: 8556861
    Abstract: Devices and methods for intradermal (ID) administration of diagnostic and therapeutic agents, vaccines and other compounds into the dermal layer of the skin are disclosed. The devices and the methods simplify the ID injection process and increase the consistency of the placement of the needle tip in the dermal space close to the skin surface allowing for a shallow cannula placement in the dermis. Furthermore, the devices and methods broaden the number of sites suitable for ID injection and make the ID injection possible with limited training.

  • Publication number: 20110224609
    Abstract: An adapter device (100, 200) for use in combination with a syringe (20) to form an assembly (10) for delivering an intradermal injection. The adapter device comprises a body (110, 210) which is connectable to the syringe. A second primary skin contacting surface (232) is positioned at a distal end (126, 226) of the body. At least one support element (140, 150, 240) is connected to the body. With the assembly in an assembled condition, the at least one support element supports a needle cannula (24) connected to the syringe. The needle cannula is supported by the at least one support element intermediate a base (26) and a tip (28) of the needle cannula. At least a terminal portion of the needle cannula extends axially in a direction substantially parallel to at least a planar portion of the second primary skin contacting surface.

  • Publication number: 20050037033
    Abstract: The present invention is directed to microbicidal compositions containing a microbicidal formulation or agent and methods of use thereof for preventing the transmission of or treating sexually transmitted infections and/or common vaginal infections, while minimizing disruptions to vaginal ecology and epithelium. In a preferred embodiment, the microbicidal formulation or agent is ciclopirox olamine. These compositions are preferably encapsulated in the form of a foam, cream, wash, gel, suppository, ovule, lotion, ointment, film, tablet, foaming tablet, tampon, vaginal spray, or aerosol. Preferably the concentration of microbicidal agent is approximately 0.01% to approximately 50% by weight, more preferably between approximately 0.1% to approximately 28%, and most preferably between approximately 0.5% and approximately 5%.

  • Patent number: 6217512
    Abstract: A visual cervical inspection apparatus for visual inspection of a cervix has a housing having a cavity. The housing has a proximal viewing aperture located in a proximal end of the housing and a distal aperture at a distal end of the housing. A light source is attached to the housing and is adapted to illuminate the cervix with light sufficient to visibly enhance the definition between cancerous and healthy cervical tissue. Magnification optics are disposed within the cavity of the housing which provide for magnified viewing of the illuminated cervix. The visibly enhanced definition between cancerous and healthy cervical tissue can thus be more easily viewed by a user of the visual cervical inspection apparatus. Light emitting diodes of the appropriate light wavelength can be used to provide the necessary illumination of the cervix. Krypton, xenon or other similar bulbs may also be used when filtered to produce light of approximately between 480-580 nanometers.
