  • Pneumatic massage system
    Patent number: 11883358
    Abstract: A pneumatic massage system includes a source of pressurized air, a fluidic switching module in communication with the source of pressurized air, a first bladder in communication with the fluidic switching module, a second bladder in communication with the fluidic switching module, and a third bladder in communication with the fluidic switching module. The fluidic switching module is configured to direct air from the source of pressurized air to each of the first bladder, the second bladder, and the third bladder in a predefined sequence. The predefined sequence includes inflating the first bladder, inflating the second bladder while deflating the first bladder, and inflating the third bladder while deflating the second bladder.
