Abstract
A compact automated external defibrillator (AED) is a device configured to receive electrocardiogram signals while the AED's electrode pads are in airtight storage. A surface of the device has a first electrical connection and a second electrical connection to a circuit board, each at a separate defined location on the surface. The circuit board receives ECG signals from a patient when the first defined location and the second defined location on the surface of the device body are put in contact with the patient. The circuit board may be configured to sense ECG signals from the patient through a plurality of additional defined locations on the surface of the device.
Core Innovation
A compact automated external defibrillator (AED) is configured to receive electrocardiogram (ECG) signals from a patient while an AED proximate pad and an AED distal pad are within airtight storage. A surface of the device body has a first electrical connection and a second electrical connection to a circuit board, each at a separate defined location on the surface, and the circuit board is an indivisible unit configured to receive ECG signals from a patient when the first defined location and the second defined location on the surface of the device body are put in contact with the patient. The circuit board may be configured to sense ECG signals from the patient through a plurality of additional defined locations on the surface of the device body.
The patent identifies that taking an ECG normally requires deploying AED pads or using larger wired ECG devices, which can impede prompt patient treatment and do not provide significant advantages in size or mobility. The disclosed solution locates ECG electrodes on a surface of the compact AED device body so an ECG can be taken without unpacking or exposing the AED proximate pad and AED distal pad to air, and provides a complete electrical circuit through the compact AED circuit board using electrodes fixed and accessible on an external surface of the device body.
Claims Coverage
This coverage identifies five main inventive features extracted from the independent claim(s).
Receiving ECG signals while pads are in airtight storage
A compact automated external defibrillator configured to receive ECG signals from a patient while an AED proximate pad and an AED distal pad are within airtight storage.
Device body for compact storage limiting air exposure
A device body configured for compact storage of the AED proximate pad and the AED distal pad, the compact storage configured to limit exposure of the AED proximate pad and the AED distal pad to air.
Circuit board as an indivisible unit within the device body
A circuit board configured as an indivisible unit within the device body, the circuit board controlling defibrillation and located within the device body behind a front body housing.
First and second electrical connections on device surface
The device body comprising a first electrical connection between the circuit board and a first defined location on a surface of the device body and a second electrical connection between the circuit board and a second defined location on the surface, said surface configured to not increase exposure of the AED proximate pad and the AED distal pad to air.
Circuit board receives ECG signals when locations contact patient
The circuit board configured to receive the ECG signals from the patient when the first defined location and the second defined location on the surface of the device body are put in contact with the patient.
The independent claim centers on a compact AED that preserves pad airtight storage while providing surface-mounted electrical connections and an indivisible internal circuit board that together enable sensing of ECG signals when defined surface locations contact a patient.
Stated Advantages
Enables an easier, more accurate, and more mobile method for assessment of emergency and non-emergency medical conditions.
Allows an emergency medical technician (EMT) to take an ECG using a compact AED without using a large, heavier AED or ECG device.
Allows non-medically trained people to easily and quickly take their own ECGs outside of a medical environment without deploying the AED pads.
Permits replacement of a disposable cartridge containing sealed pads with a cartridge containing ten electrodes to obtain a traditional 12-lead ECG, providing a mobile ECG platform that doubles as an AED.
Enables a reusable AED once the AED pads are replaced, which reduces replacement costs and adds functionality.
Extends the life of the AED by allowing hydrogel, or other adhesive, to be replaced prior to or after expiration.
Allows use of pads having different sizes and complies with IEC60601-2-4 requirements for total area and minimum individual area.
Allows re-use of AED electrodes and circuitry to provide on-demand single lead ECG, on-demand 6-lead ECG, and 12-lead ECG for purposes beyond determination of shockable arrhythmias or CPR.
Documented Applications
Use in emergency and non-emergency medical assessment to evaluate and baseline patient conditions.
Enabling EMTs to take ECGs using a compact AED in the field without deploying AED pads.
Permitting non-medically trained individuals to take ECGs outside medical environments for health care maintenance, recording, tracking and reporting diagnostic data to medical providers.
Providing a mobile ECG platform that can be converted to obtain a traditional 12-lead ECG by replacing a disposable cartridge containing electrodes.
Industrial applicability to the medical industry.
