Fluid Amplifiers Patents (Class 128/DIG10)
  • Patent number: 6110292
    Abstract: Fluidic oscillators are used to apply pulsatile sweeping streams of a liquid, preferably a cleansing solution, to selected areas of epidermis in a manner consistent with the resonant characteristics of the epidermis. The device thereby cleanses the skin, pores, and folds of microorganisms.

  • Patent number: 3973558
    Abstract: An improved oral irrigation technique is characterized by an oscillatory swept water jet issued to sweep back and forth at high frequencies across the user's gums and teeth. High frequency operation is achieved by oscillating the jet itself rather than the jet-issuing body. The high frequency sweeping jet effects faster cleaning action and more effective gum massage than prior art pulsed jet irrigators having lower effective operating frequencies.

  • Patent number: 3942518
    Abstract: An apparatus for intermittently applying compression to a portion of a patient's body enclosed in a therapeutic appliance. A timer is operated from a regulated pressurized fluid source to generate control signals to a valve which alternately inflates and deflates the appliance. The elements of the timer may be time delay valves, penumatic timing valves or fluidic elements which function to produce adjustable timing intervals for the control signals whereby the inflation and deflation intervals and the cycle time may be manually changed.
