Abstract

The utility model discloses a WLAN real time cardiogram transmitting detecting system, comprising a cardiogram lead wire, an amplifying circuit, a filter circuit, a CPU module, a power supply module, a WLAN module, a memorizer, a wireless router, an Ethernet and a server. An ecg signal collected from human body surface is amplified by the amplifying circuit. After a 50 Hz interfering signal is filtered by the filter circuit, the ecg signal is sent to the CPU module and then is stored in the memorizer after the analog-to-digital conversion of the CPU module. At the same time, the ecg digital signal is sent to the WLAN module. The ecg signal sent by the WLAN module is received by the wireless router and is transmitted to the server by the Ethernet. The ecg signal is analyzed and stored by a special dynamic ecg analysis software; consequently, the real time monitoring of the ecg signal of the user is realized. The utility model can store the dynamic ecg data for 24 hours continuously like a cardiogram HOLTER recorder, transmit the ecg data in real time over long distances and accomplish the cross-regional consultation and the treatment of the dynamic cardiogram.

Description

WLAN transmits Electrocardiographic detection system in real time

Technical field

This utility model relates to a kind of by the Electrocardiographic detection system of the real-time transmission of WLAN.Be applicable to the inspection of cardiovascular disease, belong to medical Instrument field.

Background technology

Electrocardiogram is mainly used in characteristic and quantitative analysis diagnosis such as the arrhythmia of cardiovascular disease and myocardial ischemia, utilizes electrocardiogram monitor that electrocardiosignal is noted, and sends to the IP end of LAN or wide area network again through WLAN.The recipient of IP end is a PC, and the software of PC can be analyzed, and in artificial presence, electrocardiosignal is made final diagnosis.

Existing prevailing implementation method is the electrocardiogram that hospital uses electrocardiograph record patient, requires patient to lie in bed, and can not write down the electrocardiogram (ECG) data of patient in orthobiosis.Though the portable dynamic electrocardiograph does not require that patient lies in bed in hospital, patient carries out data to hospital and reads behind the record electrocardiogram (ECG) data, can not monitor patient in real time.Useful in addition landline telephone is uploaded data, and telephone charge is more expensive.

WLAN is current just at a kind of equipment of high speed development, and its transmission speed height can connect with wired network is convenient at automatically switching network under the low speed.

The agreement that wireless LAN communication uses is (802.11a/b/g), according to the difference of residing WLAN, uses corresponding protocol automatically.Pass through wireless local area network communications module, the data that electrocardiogram equipment can be collected are transferred to special-purpose PC or electrocardiogram (ECG) data processing terminal equipment wirelessly and carry out analyzing and processing, the data of transmission can be current real-time electrocardiogram (ECG) datas, also can be the data that have been recorded on the storage medium.

Adopt wireless local area network technology to carry out transfer of data, have following several big advantage:

1, message transmission rate height, the reliability height.Wireless local area network technology (802.11a b g), when carrying out transfer of data, transfer rate can reach 11Mb/s, 54Mb/s even higher in theory, definitely can satisfy the requirement of the real-time Transmission of multichannel electrocardiogram (ECG) data.Use Transmission Control Protocol in the communication, guaranteed the reliability of electrocardiogram (ECG) data transmission.

2, WLAN has reached very high coverage rate in a lot of big cities, can pass through WLAN, realize whenever and wherever possible patient's electrocardio being monitored in real time, increased the mobility of equipment greatly, this diagnosis for the heart patient has very big meaning with monitoring.Simultaneously, use the price of WLAN generally low, realize that by WLAN the function of monitoring in real time has the advantage of relative low price than the price of using mobile communications network.

Summary of the invention

The purpose of this utility model provides a kind of WLAN and transmits Electrocardiographic detection system in real time.

WLAN of the present utility model transmits Electrocardiographic detection system in real time, comprises electrocardiogram acquisition and transmission and electrocardio receiving and analyzing two parts; Electrocardiogram acquisition and hop comprise cardiac diagnosis lead-line, amplifying circuit, filter circuit, CPU module, supply module, Wireless LAN module and memorizer, cardiac diagnosis lead-line, amplifying circuit, filter circuit and CPU module link to each other successively, and Wireless LAN module links to each other with the CPU module respectively with memorizer; The electrocardio receiving and analyzing partly comprises wireless router, Ethernet and server, and wireless router, Ethernet and server link to each other successively.

During use, the electrocardiosignal input amplifying circuit that cardiac diagnosis lead-line is gathered human body surface, after amplifying, amplifying circuit delivers to filter circuit, filter circuit filtering 50Hz interfering signal, deliver to the AD end of CPU module, after CPU module analog digital conversion, be stored in the memorizer, simultaneously electrocardiographicdigital digital signals is delivered to Wireless LAN module, the electrocardiosignal that Wireless LAN module sends is received by the wireless router of electrocardio receiving and analyzing part, the electrocardiographicdigital digital signals that wireless router receives is sent in the server through Ethernet, server is analyzed the data of receiving by the dynamic electrocardiogram analysis software of special use, storage, thus realize the user electrocardiosignal is monitored in real time.

The beneficial effects of the utility model are:

This utility model not only has 24 hours the dynamic electrocardiogram (ECG) data effect of storage continuously of electrocardiogram HOLTER monitor, also have by WLAN and change wired network, the remote function that transmits dynamic electrocardiogram (ECG) data in real time, can receive, monitor user dynamic electrocardiogram information in real time, the consultation of doctors treatment that provides hardware platform, user to wait trans-regional, transprovincially to carry out dynamic electrocardiogram for diagnosis treatment.

WLAN of the present utility model transmits in real time Electrocardiographic detection system when transfer of data, does not need as traditional electrocardiogram HOLTER out of servicely, and the data with ECG analysis system are connected on the computer from the memorizer taking-up again, read and analyze.This utility model can directly obtain electrocardiogram (ECG) data from server end wirelessly, and in the process of transfer of data, Electrocardiographic detection system can non-stop run, makes data transmission procedure become easy.
