Pocket-Sized Automated External Defibrillator - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240017080 titled 'Pocket-Sized Automated External Defibrillator

Simplified Explanation

The abstract describes an automated external defibrillator (AED) device that includes various components such as a high voltage capacitor (HV cap), batteries, a DC/DC converter circuit, an H-bridge circuit, and a memory and microprocessor. These components are contained in a pocket-sized housing. The AED device continuously monitors and adjusts the rate at which the batteries charge the HV cap and includes a variable frequency relaxation oscillator circuit to acquire a patient's z-body measurement.

  • The AED device includes a high voltage capacitor (HV cap) to store energy for delivering a defibrillation shock to a patient.
  • Batteries are used to charge the HV cap.
  • The DC/DC converter circuit consists of a high voltage transformer, a FET switch with an associated driver, and a rectifying diode.
  • The H-bridge circuit transforms the energy released from the HV cap into a bi-phasic pulse.
  • The memory and microprocessor operate the AED device.
  • The components, including the HV cap, DC/DC converter circuit, H-bridge circuit, batteries, memory, and microprocessor, are contained in a pocket-sized housing.
  • The AED device continuously monitors and adjusts the charging rate of the batteries to the HV cap.
  • The AED device includes a variable frequency relaxation oscillator circuit to acquire a patient's z-body measurement.

Potential Applications:

  • Emergency medical services: The AED device can be used by paramedics and other medical professionals to deliver defibrillation shocks to patients experiencing cardiac arrest.
  • Public spaces: AED devices can be installed in public areas such as airports, shopping malls, and sports stadiums to provide immediate assistance in case of sudden cardiac arrest.

Problems Solved:

  • Lack of immediate access to defibrillation: The AED device provides a portable and easily accessible solution for delivering defibrillation shocks, potentially saving lives in emergency situations.
  • Inefficient charging of the HV cap: The AED device continuously monitors and adjusts the charging rate of the batteries to ensure efficient energy storage in the HV cap.

Benefits:

  • Portability: The pocket-sized housing makes the AED device highly portable and easy to carry in emergency situations.
  • Continuous monitoring and adjustment: The AED device continuously monitors and adjusts the charging rate of the batteries, ensuring optimal energy storage for effective defibrillation.
  • Z-body measurement: The variable frequency relaxation oscillator circuit allows the AED device to acquire a patient's z-body measurement, potentially providing additional information for accurate defibrillation.


Original Abstract Submitted

automated external defibrillator (aed) devices may include a high voltage capacitor (hv cap) configured to store energy required to deliver a defibrillation shock to a patient; batteries configured to charge the hv cap; a dc/dc converter circuit including a high voltage transformer, a fet switch with associated driver, and a rectifying diode; an h-bridge circuit configured to transform energy released from the hv cap into a bi-phasic pulse; and a memory and microprocessor configured to operate the aed device. in particular, the hv cap, the dc/dc converter circuit, the h-bridge circuit, the one or more batteries, and the memory and the microprocessor may contained in a pocket-sized housing, the aed device may be configured to continuously monitor and adjust the rate at which the batteries charge the hv cap, and the aed device may include a variable frequency relaxation oscillator circuit configured to acquire a patients z-body measurement.
