  • Patent number: 4230663
    Abstract: A "cold" gas sterilization process that operates at temperatures below 80.degree. C. in a temperature range that is generally considered nonsporicidal. The process is capable of sterilizing with gaseous hydrogen peroxide at extremely low concentrations in a gas phase, such as 0.5 mg/L. The widely used process of "cold" sterilizing with ethylene oxide is typically run at a gas concentration of 630 mg/L and 55.degree. C. Apparatus is also disclosed for use of this process in "cold" sterilization of contact lenses.
    Type: Grant

  • Patent number: 4153050
    Abstract: A device for applying intermittent compression to a body member, such as a leg, of a patient is disclosed. This device has a highly elastic stocking of the antiembolism type with an inelastic external panel secured to a portion of the stocking's circumference to provide a bladder cavity and restrict circumferential stretching of only a portion of the stocking. The inelastic panel has an openable structure, and internal bladder retaining pockets. An inflatable bladder includes an inner shaping panel causing the bladder to more readily conform to the shin area of the leg.
