  • Patent number: 8591439
    Abstract: An extended term resuscitation system includes a plurality of inflatable cuffs adapted to extend around separate portions of the anatomy of a patient (i.e. the chest, abdomen and legs) for enhancing the circulation when inflated/deflated periodically. A primary low-pressure-high-volume air compressor is in fluid communication with each of the cuffs through individual air handlers. The air handlers are formed with an inflation and a deflation diaphragm valve which, under the control of an electronic timer and a pneumatic circuit, connect the respective cuff to the output of the compressor for inflation or to the atmosphere for deflation. A secondary air compressor provides air under suitable pressure to the pneumatic circuit for the control of the diaphragm valves. As an option the operator may change the cyclical rate and cuff pressure. A ventilator provides oxygen to the patient in selected volumes or on demand.

  • Patent number: 8277399
    Abstract: A patient resuscitation/respiratory system includes a system control unit with a timer module controlling a plurality of air pressure modules. In an exemplary embodiment, the air pressure modules include a first air pressure module for controlling a first flow of pressurized gas from a first pressurized gas supply to an inflatable abdominal cuff, a second air pressure module for controlling a second flow of pressurized gas from the first gas supply to an inflatable chest cuff, and a third air pressure module for controlling a third flow of pressurized gas from the first gas supply to an inflatable leg cuff. The control unit in this embodiment includes a ventilator supply module for controlling a flow of breathable gas from a second pressurized gas supply to a patient ventilator module to periodically connect the patient ventilator module and the patient's lungs to the breathable gas supply.
