PROBLEM TO BE SOLVED: To provide a pressurization respiratory gas humidifier adapter with a pressure relief valve having an audible signal generator at a small flow respiratory gas feed system as incorporated in the system. SOLUTION: The adaptor is for protecting the pressure relief valve and the audible signal generator from accidental damage during use of a humidifier system, especially during connection of the adaptor 30 to a respiratory gas supply system, and when the adaptor is connected to a humidifier container before the adaptor is coupled to the gas feed system. The pressure relief valve and the audible signal generator are incorporated in the humidifier adaptor to form a gas-tight seal to a standard type medical humidifier container. The pressure relief valve alleviates pressure in a humidifier gas system for adjustment when trouble occurs in a gas passage to a patient, while generating audio sound generated at a prescribed pressure threshold level through a desired respiratory gas flow range.

摘要:
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. The timer module is configured to automatically cycle the plurality of air pressure modules to periodically inflate and deflate the cuffs in a resuscitation mode. The system control unit in a portable embodiment may be battery powered, and the gas supplies may be portable compressed gas cylinders.
