Abstract:
1. A patient resuscitation/respiratory system, comprising: a housing; a system control unit disposed within the housing, the system control unit including: a timer module; a plurality of air pressure modules, including a first air pressure module for controlling a first flow of pressurized gas from a first pressurized gas supply to an inflatable abdomen 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; each of said plurality of air modules comprising a pressure regulator with an on/off function controlled by the timer module, such that in a regulator-on mode, a regulator main valve is open to pressurize the respective cuff associated with the air module, and said regulator main valve is closed during a regulator-off mode; each air module having an inlet for receiving the pressurized gas during the regulator-on mode, an outlet chamber through which gas flows to or from the respective cuff, a reference pressure chamber and a pressure compensated discharge valve connected between the outlet chamber and the ambient, the module being arranged to establish a preset pressure in the reference chamber when the regulator is in the on-mode and ambient pressure in the reference chamber when the regulator is in the off-mode, the discharge valve sensing the pressures in the reference chamber and the outlet chamber and connecting the outlet chamber to the ambient when the pressure in the outlet chamber is a small amount higher than the reference pressure whereby the pressure compensated discharge valve functions as a relief and a discharge valve depending on the status of the pressure regulator; 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 second pressurized gas supply; each air module further including an air injection system for diluting said first flow, said second flow and said third flow of pressurized gas from the first pressurized gas supply in the regulator on-mode with ambient air and for preventing release of gas from the respective cuffs through said air injection system during the regulator-off mode; the timer module configured to automatically cycle the plurality of air pressure modules to periodically inflate and deflate the cuffs in a resuscitation mode.
