Abstract
A system that includes both an Airway and Ventilation device (AV) and an Automated External Defibrillator (AED) device is described. The system allows minimally trained persons to operate it in emergency situations involving respiratory failure and/or cardiac arrhythmias. An integral part of the AV of the system is a face mask manufactured in two parts: a face attachment unit configured to attach to the patient's face and a mask body that is releasably connected to the face attachment unit by a quick release mechanism allowing quick removal of the mask body from the face attachment unit, leaving only the face attachment unit attached to the patients' face, in order to address urgencies such as vomiting. After vomiting ceases and is cleared, then the mask body may be reattached to continue ventilation.
Core Innovation
The document describes a system configured to assist minimally trained persons to operate it in emergency situations involving respiratory failure and/or cardiac arrhythmias. The system integrates an Airway and Ventilation device with an Automated External Defibrillator so that the operator can receive audible or visual instructions while vital signs and ECG data are monitored and recorded.
The face mask comprises a face attachment unit configured to be attached and secured to the face of a patient by connectors that ensure a tight fitting to face contours, and a mask body releasably connected to the face attachment unit by a quick release/attachment mechanism. The mask body comprises a hollow tube that passes from an interior side to an exterior side and provides a mouth airway securing channel, together with a CO2 sensor configured to measure end tidal CO2 in exhalations and a ventilation tube connected to a portable ventilator for delivering air or oxygen and removing exhaled air.
The quick release/attachment mechanism allows quick removal of the mask body from the face attachment unit, leaving only the face attachment unit attached while leaving the mouth and nose exposed to the surroundings. Processor and dedicated software determine when to apply electric shock according to evaluation of the state of ventilation, where the state of ventilation is evaluated according to the end tidal CO2 measured in each chest compression applied by the operator to the patient.
Claims Coverage
The provided independent claim covers six inventive features: an integrated emergency system for minimally trained operators, a quick-release face mask with face attachment unit, an ETCO2 mouth airway securing channel and ventilation tube, rapid mask body removal leaving mouth and nose exposed, shock timing determination based on ventilation state from ETCO2 during chest compressions, and AED ECG detectors with monitoring and electrical shock via chest pads.
Integrated emergency system for minimally trained operators
A system configured to assist minimally trained persons in emergency situations involving respiratory failure and/or cardiac arrhythmias, comprising an Airway and Ventilation device and an Automated External Defibrillator, with a user interface for audible or visual instructions, communication functionality, and a data management unit that operates the system, provides instructions, and records ECG and vital-signs data.
Quick-release face mask with face attachment unit
A face mask comprising a face attachment unit configured to be attached and secured to the face of a patient by connectors that ensure a tight fitting to face contours, and a mask body releasably connected to the face attachment unit by a quick release/attachment mechanism.
ETCO2 mouth airway securing channel and ventilation tube
A face mask body configured to include a hollow tube passing from the interior side to the exterior side and configured to provide a mouth airway securing channel, a CO2 sensor configured to measure end tidal CO2 in exhalations, and a ventilation tube connected to a portable ventilator configured to deliver air or oxygen to the patient and to remove exhaled air.
Rapid mask body removal leaving mouth and nose exposed
A quick release/attachment mechanism configured to allow quick removal of the mask body from the face attachment unit, leaving only the face attachment unit attached by the connectors to the patient’s face and leaving the mouth and nose of the patient exposed to the surroundings.
Shock timing determination based on ventilation state from ETCO2 during chest compressions
Processor and dedicated software configured to determine when to apply electric shock according to evaluation of the state of ventilation, wherein the state of ventilation is evaluated according to the ETCO2 measured in each chest compression applied by the operator to the patient.
AED ECG detectors with monitoring and electrical shock via chest pads
An Automated External Defibrillator comprising one or more electrocardiogram detectors adapted to be attached to the chest of the patient and configured to both monitor ECG and to apply electrical shock to the patient via one or more chest pads.
The claim coverage combines the integrated emergency system with the specialized quick-release airway and ventilation mask, ETCO2 sensing, portable ventilator interface, and processor-controlled shock timing based on ventilation-state evaluation from ETCO2, while the AED monitors ECG and delivers shock through chest pads.
