WEARABLE DEFIBRILLATOR WITH OUTPUT STAGE HAVING DIVERTING RESISTANCE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240050759 titled 'WEARABLE DEFIBRILLATOR WITH OUTPUT STAGE HAVING DIVERTING RESISTANCE

Simplified Explanation

Abstract Explanation

The abstract describes an external defibrillator that includes a special output stage for delivering high-voltage defibrillation pulses. The output stage consists of switches that can turn on to deliver the pulse and turn off during other times. It also includes a diverting resistance to prevent electrical current leakage into the patient while a capacitor is being charged. Additionally, there is an optional detector to notify if any component is malfunctioning. The use of semiconductor switches in the output stage instead of relays allows for a lighter and more compact external defibrillator, which is particularly advantageous for wearable defibrillator applications.

Patent/Innovation Explanation

  • The external defibrillator includes a special output stage with switches for delivering high-voltage defibrillation pulses.
  • The switches can turn on and off, ensuring the pulse is delivered only when needed.
  • A diverting resistance is included to prevent electrical current leakage into the patient during capacitor charging.
  • Semiconductor switches are used instead of relays, reducing weight and volume of the defibrillator.
  • The lighter weight and smaller size make the defibrillator more suitable for wearable applications.
  • An optional detector can identify any malfunctioning component, ensuring the device operates properly.

Potential Applications

  • Medical settings: External defibrillators can be used in hospitals, clinics, and emergency medical services to treat cardiac arrest.
  • Wearable defibrillators: The compact and lightweight design makes the technology suitable for wearable devices that can be worn by individuals at risk of sudden cardiac arrest.

Problems Solved

  • Weight and volume: The use of semiconductor switches instead of relays reduces the weight and volume of the external defibrillator, making it more portable and easier to carry.
  • Electrical current leakage: The inclusion of a diverting resistance prevents electrical current from leaking into the patient during capacitor charging, ensuring the safety of the procedure.
  • Component malfunction: The optional detector can identify any malfunctioning component, allowing for timely repairs or replacements and ensuring the device functions properly.

Benefits

  • Portability: The reduced weight and volume of the external defibrillator make it easier to carry, especially in wearable defibrillator applications.
  • Safety: The diverting resistance prevents electrical current leakage into the patient, enhancing the safety of the defibrillation procedure.
  • Reliability: The optional detector helps identify any malfunctioning component, ensuring the device operates reliably and effectively.


Original Abstract Submitted

in embodiments, an external defibrillator has an electrical circuit with a special output stage for the high-voltage defibrillation pulse. the output stage includes switches that can turn on for delivering the pulse, and off during all other times. the output stage also includes a diverting resistance to divert electrical current that could leak into the patient while a capacitor is being charged. an optional detector may notify if a component is malfunctioning. an advantage can be that an external defibrillator may be created according to embodiments that uses, in its output stage, semiconductor switches instead of relays. as semiconductor switches weigh less and occupy less volume than relays, an external defibrillator according to embodiments may have less weight and volume. especially in wearable defibrillator applications, less weight means less effort to carry and less volume means easier concealment under clothing.
