The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, this utility model 12 is led cardiac electric recording apparatus, comprise ecg signal acquiring pretreatment module 13, body position sensor 12, processing and control element (PCE) 11 and communication unit 18, wherein processing and control element (PCE) 11 is connected with information display module 14, key-press module 15, energy supply control module 16 and data memory module 17 respectively by interface.

As shown in Figure 2, of the present utility model 12 lead processing and control element (PCE) described in the cardiac electric recording apparatus 11 adopts the STR910F microprocessor of ST company, it is connected with the mba140 body position sensor 12 that is adopted by ADC interface 27, is used for that position information is transformed into digital signal and handles and store; It also is connected with ecg signal acquiring pretreatment module 13 by the serial data mouth; It also is connected with the GPRS module 31 of described communication unit 18 by UART bus 30, thereby wireless data transmission just can be realized in the place that is implemented in GPRS network.

Wherein said communication unit 18 includes GPRS module 31, USB interface 28 and local network interface 29.

Described ecg signal acquiring pretreatment module 13 has adopted synchronous 8 tunnel signal acquisition module, and it is made up of one stage signal amplification module, bandpass filtering modules block, 50Hz trap band resistance module, second signal amplification module and ADC module, and each module is connected successively.Ecg signal acquiring need obtain useful small-signal under strong relatively noise background, so the one-level amplification module adopts precision instrument amplifier AD620, the secondary amplification module adopts the TLC27L4 integrated operational amplifier, adds that filtration module and trap module form the electrocardiosignal amplification module in the lump.
