Respiratory ventilatory device and method of operating same

A method of operating a respiratory ventilator device including an inhaled air assembly including an injector diaphragm housing including a flexible injector diaphragm dividing an interior volume of the injector diaphragm housing into an inhalation air chamber containing inhalation air and a compressed air chamber for containing compressed air, an inhalation inlet line coupled to the injector diaphragm housing for channeling the inhalation air from a supply of inhalation air into the inhalation air chamber, and an inhalation outlet line coupled to the injector diaphragm housing for delivering the inhalation air from the inhalation air chamber to a patient respiratory circuit, an exhaled air assembly including an extractor diaphragm housing including a flexible extractor diaphragm dividing an extractor interior volume of the extractor diaphragm housing into an exhalation air chamber and a second compressed air chamber, an exhalation inlet line coupled to the extractor diaphragm housing for channeling exhaled air from the patient respiratory circuit into the exhalation air chamber, and an exhalation outlet line coupled to the extractor diaphragm housing for delivering the exhaled air from the exhalation air chamber to an exhaust air collection system, a pneumatic compressed air assembly coupled to the injector diaphragm housing and the extractor diaphragm housing, and a control system including a processor operatively coupled to the pneumatic compressed air assembly, the method including the processor performing an algorithm for operating the respiratory ventilator device including the steps of:

• operating the pneumatic compressed air assembly in a first phase including the injector diaphragm and the extractor diaphragm in a center position;
• and
• operating the pneumatic compressed air assembly in a second phase including delivering compressed air into the injector diaphragm housing to move the flexible injector diaphragm to channel inhalation air from the injector diaphragm housing to the patient respiratory circuit.

A non-transitory computer-readable storage media having computer-executable instructions embodied thereon to operate a respiratory ventilator device including an inhaled air assembly including an injector diaphragm housing including a flexible injector diaphragm dividing an interior volume of the injector diaphragm housing into an inhalation air chamber containing inhalation air and a compressed air chamber for containing compressed air, an inhalation inlet line coupled to the injector diaphragm housing for channeling the inhalation air from a supply of inhalation air into the inhalation air chamber, and an inhalation outlet line coupled to the injector diaphragm housing for delivering the inhalation air from the inhalation air chamber to a patient respiratory circuit, an exhaled air assembly including an extractor diaphragm housing including a flexible extractor diaphragm dividing an extractor interior volume of the extractor diaphragm housing into an exhalation air chamber and a second compressed air chamber, an exhalation inlet line coupled to the extractor diaphragm housing for channeling exhaled air from the patient respiratory circuit into the exhalation air chamber, and an exhalation outlet line coupled to the extractor diaphragm housing for delivering the exhaled air from the exhalation air chamber to an exhaust air collection system, a pneumatic compressed air assembly coupled to the injector diaphragm housing and the extractor diaphragm housing, and a control system including a processor operatively coupled to the pneumatic compressed air assembly,

• when executed by the processor the computer-executable instructions cause the processor to perform an algorithm including the steps of:
• operating the pneumatic compressed air assembly in a first phase including the injector diaphragm and the extractor diaphragm in a center position;
• and
• operating the pneumatic compressed air assembly in a second phase including delivering compressed air into the injector diaphragm housing to move the flexible injector diaphragm to channel inhalation air from the injector diaphragm housing to the patient respiratory circuit.
