Abstract

A defibrillator device is provided. The defibrillator device includes a first electrode, a second electrode, a readout module, a USB interface, a voltage converter and a stimulation module. When the first and second electrodes contact the chest of a patient, the readout module obtains a physiologic rhythm signal of the patient and provides a heart rhythm signal according to the first physiologic rhythm signal. According to a first voltage from a portable electronic device, the voltage converter generates a second voltage when the first USB interface is coupled to the portable electronic device, wherein the second voltage is larger than the first voltage. When the physiologic rhythm signal indicates that cardiac arrhythmia is present in the patient, the stimulation module provides an electric shock energy to the chest of the patient via the first and second electrodes according to the second voltage.

First claim

What is claimed is:

1. A defibrillator device, comprising:
a first electrode;
a second electrode;
a readout module coupled to the first and second electrodes, obtaining a first physiologic rhythm signal of a patient when the first and second electrodes contact a chest of the patient, and providing a heart rhythm signal according to the first physiologic rhythm signal;
a first USB interface;
a voltage converter directly coupled to the first USB, wherein according to a first voltage from a portable electronic device via the first USB interface, the voltage converter generates a second voltage when the first USB interface is coupled to the portable electronic device, wherein the second voltage is higher than the first voltage;
a stimulation module coupled to the first and second electrodes and the voltage converter, providing an electric shock energy to the chest of the patient via the first and the second electrodes according to the second voltage when the first physiologic rhythm signal indicates that cardiac arrhythmia is present in the patient;
a memory, storing an application; and
a controller coupled to the first USB interface, the readout module and the stimulation module, receiving the heart rhythm signal from the readout module, and determining whether the cardiac arrhythmia is present in the patient according to the heart rhythm signal,
wherein when the cardiac arrhythmia is present in the patient, the controller controls the stimulation module according to the application stored in the memory to provide the electric shock energy to the chest of the patient.

2. The defibrillator device as claimed in claim 1 , wherein after the stimulation module provides the electric shock energy to the chest of the patient, the readout module re-obtains a second physiologic rhythm signal from the patient via the first and second electrodes, and the readout module provides a second heart rhythm signal according to the second physiologic rhythm signal, and the controller determines whether to continue performing the electric shock procedure according to the second heart rhythm signal, wherein when the second heart rhythm signal indicates that the heart rhythm of the patient is normal, the controller stops performing the electric shock procedure.

3. The defibrillator device as claimed in claim 1 , further comprising:
a display interface, displaying an execution state of the electric shock procedure.

4. The defibrillator device as claimed in claim 1 , further comprising:
a Bluetooth module, communicating with a mobile phone when the electric shock energy is provided to the chest of the patient, so as to provide the heart rhythm signal to the mobile phone, and to call an emergency call or provide a location of the patient to an emergency rescue unit.

5. The defibrillator device as claimed in claim 4 , wherein the portable electronic device is a mobile power unit.

6. A defibrillator system, comprising:
a portable electronic device; and
a defibrillator device, comprising:
a first electrode;
a second electrode;
a readout module coupled to the first and second electrodes, obtaining a first physiologic rhythm signal of a patient when the first and second electrodes contact a chest of the patient, and providing a heart rhythm signal according to the first physiologic rhythm signal;
a first USB interface;
a voltage converter directly coupled to the first USB, wherein according to a first voltage from the portable electronic device via the first USB interface, the voltage converter generates a second voltage when the first USB interface is coupled to the portable electronic device, wherein the second voltage is higher than the first voltage;
a stimulation module coupled to the first and second electrodes and the voltage converter, providing an electric shock energy to the chest of the patient via the first and the second electrodes according to the second voltage when the first physiologic rhythm signal indicates that cardiac arrhythmia is present in the patient;
a memory, storing an application; and
a controller coupled to the first USB interface, the readout module and the stimulation module, receiving the heart rhythm signal from the readout module, and determining whether the cardiac arrhythmia is present in the patient according to the heart rhythm signal,
wherein when the cardiac arrhythmia is present in the patient, the controller controls the stimulation module according to the application stored in the memory to provide the electric shock energy to the chest of the patient,
wherein the portable electronic device is a mobile power unit.
