Embodiment Construction

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0045] Such as figure 1 As shown, the present invention provides a portable heart defibrillator based on Bluetooth, including a controller 110, an ECG acquisition module 120, a Bluetooth module 130, a charging and discharging module 140, an A / D converter 150, a display circuit 160, and a button circuit 170.

[0046] Wherein, the controller 110 selects STM32F103ZET6 chip, which is a 32-bit microprocessor with fast processing speed and complete functions.

[0047] The overall structure of the portable cardiac defibrillator is that the controller 110 controls the ECG acquisition module 120 to collect human ECG signals and realize amplification and filtering. After the ECG signals are collected, the ECG waveform is displayed on the smart phone 180 through the Bluetooth module 13...

Abstract

The invention discloses a portable cardiac defibrillator based on Bluetooth. The portable cardiac defibrillator based on Bluetooth comprises a controller, an electrocardio acquisition module, a Bluetooth module and a charge-discharge module. The electrocardio acquisition module is used for acquiring electrocardio signals and is connected with the controller through an A / D converter so as to convert electrocardio analog signals into electrocardio digital signals and transmit the signals to the controller. The Bluetooth module is connected with the controller and used for wireless data transmission with a mobile phone. The charge-discharge module is connected with the controller and is used for conducting electric defibrillation on the human body after being charged under the control of the controller. Compared with existing portable cardiac defibrillators, the portable cardiac defibrillator based on Bluetooth has the advantages that the Bluetooth communication technology is integrated with an advanced acquisition circuit, so that correct electrocardio signals can be obtained, and data can be sent to the mobile phone. The invention further provides an electrocardiosignal acquisition method of the portable cardiac defibrillator based on Bluetooth.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a portable heart defibrillator based on bluetooth. Background technique [0002] The term "ventricular fibrillation" has actually been around for a long time, and people's knowledge and understanding of it is becoming more and more comprehensive. There are many scientists who have made outstanding contributions. Early defibrillation can be traced back to 1882. American scientists Battelli and Prevost confirmed through experiments that high-intensity alternating current is of great help to defibrillation. In 1887, Mcwilliam eliminated ventricular fibrillation under chloroform anesthesia by inducing direct electric shock to the heart, although it could not be recorded by electrocardiogram (ECG) at that time. In 1938, Beck and Wiggers experimented with electrical defibrillation on dogs and achieved success; the real clinical application began in 1947, when Beck used AC ele...
