  • Patent number: 6752817
    Abstract: A pressure ring for a lancing device for holding open a skin puncture while collecting a blood sample includes a collar that fits onto the end of a lancing device. A skirt is provided on the collar and a flared portion depends from the skirt. At least one axial slit is formed in the skirt. The pressure ring is made of a flexible material such as polypropylene such that when the lancing device with a pressure ring is placed on a person's skin and pressure is applied, the slits spread apart stretching the skin for a puncture by a lance in the lancing device. Once a puncture has been made, the pressure ring holds the puncture wound open to allow bleeding. Removing the lancing device from the puncture site releases the skin allowing the puncture wound to close.

  • Patent number: 6752917
    Abstract: A novel process for the continuous preparation of perfluorinated organic compounds by electrochemical fluorination of the parent non-fluorinated or partially fluorinated organic compounds, in which the quantity of charge which the electrolyte can still take up is kept in the range from about 5 Ah per kg of electrolyte to about 600 Ah per kg of electrolyte during the electrochemical fluorination, can be operated continuously over a prolonged period of time without the electrode area-time yield decreasing over time and without the formation of polymeric by products occurring.
