The specific embodiment
Below in conjunction with accompanying drawing this utility model is described further, but embodiment of the present utility model is not limited to this.
As shown in Figure 1, be provided with electrocardio amplifying circuit module, filter circuit, A/D modular converter, microcontroller and bluetooth module in the electrocardio sampling module of the present utility model, A/D modular converter, bluetooth module are connected respectively on the master controller.The electrocardio sampling module is had the inclination electrical interface, and the electrocardio interface connects the electrocardiogram acquisition module.The electrocardiosignal of human body is passed through signal conditioning circuit, electrocardio amplifying circuit again by the cardiac diagnosis lead-line collection, is connected the collection of MSP430 control electrocardiosignal at last with the A/D modular converter by the electrocardio interface.MSP430 is transferred to the electrocardiogram parameter that collects on the smart machines such as being wirelessly transmitted to mobile phone on the bluetooth module by the wireless module interface, can realize analyzing and processing and demonstration to ECG data.
As shown in Figure 2, use the INA332 amplifying circuit of 3V running voltage that the electrocardiosignal of gathering is amplified 10 times.
As shown in Figure 3, filter circuit adopts the adjustable active band elimination filter of asymmetric double T of Q-value, and Q-value is adjusted to suitable position, makes filter circuit have 50 hertz trap function.After the more powerful interfering signal of elimination, next adopt an in-phase amplification circuit that has the low-pass filtering function that the signal of telecommunication is amplified 100 times again, signal is reached more than the V level.
Adopt 10 built-in high-precision A modules of MSP430 to convert electrocardiosignal to digital signal.
Use the bluetooth module of specialty, this module size is little, and power consumption is little, adopts serial ports to communicate by letter with MSP430.MSP430 sends to the electrocardiogram (ECG) data that collects on the smart machine by bluetooth module.
Default software uses new algorithm that electrocardiogram (ECG) data is carried out the extraction of digital filtering and ecg-r wave on the smart machine, finally is presented on the device screen.Smart machine monitoring patient's at any time that so just can be by having Bluetooth function at one's side electrocardio.
Above-described embodiment of the present utility model does not constitute the restriction to this utility model protection domain.Any modification of within spiritual principles of the present utility model, having done, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present utility model.
