## Background
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a medical remote monitoring technology, more particularly, to a device for remotely monitoring electrophysiological data and a pathological image and a method thereof.
BACKGROUND OF THE INVENTION
In recent years, with the development of the mobile network technology, there appear cardiogram remote monitoring devices using a digital cell phone and a digital cell phone module, which apply the mobile network high speed wireless IP technology to collect and monitor the heart electrophysiological data of the patient population distributed over the society, and remotely send the data to a target hospital for analysis and diagnosis. This remote monitoring technology can treat patients in time, can reduce the mortality due to the cardiovascular disease, and becomes an important development content in the medical field for the mobile network technology.
In prior art, the digital cell phone or a baseband processor of the digital cell phone is usually coupled to a traditional cardiogram guardianship recorder through two ways, a physical connection or a short distance wireless radio frequency (RF) connection. FIG. 1 is a diagram of a discrete heart electrophysiological data remote mobile monitoring system of prior art, as in the U.S. Pat. No. 6,801,137, and the Chinese patent application No. 03116539.7. A cardiogram guardianship recorder 12 is coupled with a dedicated digital cell phone 10, and the cardiogram guardianship recorder 12 and the dedicated digital cell phone 10 are wirelessly connected to each other through a Bluetooth module. The cardiogram guardianship recorder 12 is a cardiogram signal collection system controlled by a microprocessor MCU, in which includes at least a cardiogram signal collection circuit, an Analog to digital (AD) convertor, a program memory, a data buffer memory, a system clock, a Bluetooth, a work power supply, an application software, and so on. The cardiogram guardianship recorder 12 is responsible for collecting a cardiogram analog signal data, obtaining a digital signal data via an analog to digital conversion, then buffering and storing the converted digital signal data, and transmitting the digital signal data to a Bluetooth module 11 of the dedicated digital cell phone 10 through a Bluetooth module 13. The dedicated digital cell phone 10 is an integral digital cell phone system, including an operation system and an application program. The dedicated digital cell phone 10 is responsible for receiving the data transmitted from the cardiogram guardianship recorder 12, and then processing and storing the received data. When a user requires sending data, a mobile network is registered by operating the dedicated digital cell phone. Then the monitoring data is transmitted to a target server, and an analysis process result is obtained.
The disadvantage of the above prior technology is that the monitoring data has to be received and processed continuously by means of the dedicated digital cell phone, and when the patient turns off the dedicated digital cell phone in an environment such as an air plane flight, a heart monitoring is terminated at the same time. As illustrated in FIG. 1, although part of hardware and functions of the cardiogram guardianship recorder 12 is simplified, and the powerful hardware and software functions of the dedicated digital cell phone 10 are applied more, it can just works continuously for several hours to obtain some segmented cardiogram monitoring data because of the massive power consumption of the Bluetooth transmission/reception and the operation of the digital cell phone. Such segmented cardiogram monitoring data does not have significant effect and advantage for most patient users who require a long time monitoring. Meanwhile, it can not provide 24 hours continuous monitoring data required by doctors in the hospital when they review and analyze the cardiogram data. During the usage, the patient user has to carry one dedicated digital cell phone additionally, charge or replace a battery frequently, which is inconvenient to the daily life of the user. Meanwhile, the manufacture cost of the dedicated digital cell phone is expensive, and the patient user has to afford a higher application cost.
FIG. 2 illustrates a diagram of an integrated heart electrophysiological data remote mobile monitoring system of the prior art, as in the Chinese patent applications No. 200520054381.8, 200510115114.1 and 200610030198.3. A cardiogram guardianship recorder 20 is coupled to a baseband processor 21, and the cardiogram guardianship recorder 20 and the baseband processor 21 are connected to each other through their asynchronous series data communication ports UART. The cardiogram guardianship recorder 20 includes at least a microprocessor MCU module, a cardiogram data collection module, a liquid crystal module, a keyboard module, a USB module, an external data storage card, an external data memory, a system clock, a work power supply manager, an internal multiple analog to digital (AD) convertor, an asynchronous series communication port UART, and an application program, etc., for the collection process and storage of the cardiogram data. The baseband processor 21 is a baseband processor of a general GPRS or CDMA digital cell phone, in which there is a mobile voice communication and wireless data communication module of which the cores are a microprocessor MCU and a digital signal processor, and in which there are at least a coprocessor, a system and periphery bus, a periphery bus interface, an internal data memory, a Direct Access Memory DMA, a buffer memory, a work power supply manager, a baseband unit, a frequency control unit, a system clock, a real time clock, a timer, and a periphery instrument and interface. The periphery instrument and the interface thereof include: a multiple analog to digital (AD) convertor unit, a keyboard control unit, a liquid crystal control unit, an audio process unit, an external data storage card control unit, an external data memory Flash control unit, an asynchronous series communication port UART unit, a USB controller unit, a SIM card control unit, a JTAG test unit, a radio frequency antenna, and an operation system and TCP/IP protocol, etc. As illustrated in FIG. 2, most of the function units and the periphery instruments of the baseband processor are in an idle status. When sending the monitoring data, the cardiogram guardianship recorder 20 controls the baseband processor 21 to start-up operation through the asynchronous series data communication port UART, registers with the mobile network, and makes a network data information exchange.
As the design method in FIG. 2, the primary cause is that the baseband processor is a mobile voice communication and wireless data communication chip, only the asynchronous series communication ports UART are opened, the external application and the base support of other application fields are not considered by manufacturers, and changing the base control program of the baseband processor is a very difficult work in technology. Therefore, it has to employ the cardiogram guardianship recorder 20 and the baseband processor 21 which are connected to each other through the asynchronous series communication port UART and integrated into a physical entity. In addition, there is a similar technology applying a low cost baseband processor module. However, due to the lack of TCP/IP protocol, a further expensive network processor hardware unit, for example, the IP 2000, is required between the cardiogram guardianship recorder 20 and the baseband processor module 21. The cardiogram guardianship recorder 20 may control the baseband processor 21 to be in a “sleep” status, which reduces the power consumption of the device, so as to be capable of continuously monitoring and recording cardiogram data for a long time. Moreover, the integrated structure is convenient for the user to carry and use. However, the disadvantage of such technology is that the structure of the hardware system is complicated and redundant; most of the hardware and functions, such as the multiple analog to digital (AD) convertor, within the baseband processor are idle and wasted, only the data communication function of the baseband processor gets used. Such superimposition of the low level causes not only the waste of resource and the reduction of reliability, but also a higher level of the operation power consumption. Accordingly, the whole machine requires a larger hardware space and a higher manufacture cost.

FIG. 7 is a flow chart for the main program of the application program module 200 for controlling the operation of the mobile network terminal device according to one embodiment of the present invention. As illustrated in FIG. 7, the mobile network terminal device proceeds into an initiation and a self test after power-on, and enters a standby status. In the standby status, if a “setting key” is triggered, the mobile network terminal device will proceed into a setting status. Under this status, a user information/data setting 210, a function setting 220, and a work mode setting 230 can be selected so as to make a corresponding setting. After completing the setting, the mobile network terminal device returns to the standby status. If the work mode does not be selected and/or set, a default work mode is electrophysiological data monitoring mode 230a. In the standby status, if a “running key” is triggered, the mobile network terminal device will operate according to the work mode flag. In the standby status, if a “emergency recourse key” is triggered, the mobile network terminal device will proceed into a network emergency recourse work mode 230h, and send the recourse information “I need help” to the preset target address. In the standby status, if a “power-off key” is triggered, the mobile network terminal device will turn off the power supply, and stop operating.
FIG. 8 is a flow chart illustrating the process steps of the mobile network terminal device in the electrophysiological data monitoring mode. The mobile network terminal device proceeds into electrophysiological data monitoring work status 230a, set the previous network online flag to be zero according to the work mode flag, reads an access point domain name APN and a remote target server IP address stored in the external data memory 107, registers with the GPRS mobile network, establishes a data connection to the target server, and sends a local host user flag and a service category request flag to the target server. The mobile network terminal device sets the network online flag to be 1 according to a response flag replied from the remote target server, controls the microprocessor unit (MCU) of the GPRS baseband processor 100 to enter a sleep status, maintains a network online connection. Meanwhile, the mobile network terminal device sets the interrupt frequency of the timer unit GPTn of the GPRS baseband processor module 100 to be an integer power of 2, sets the interrupt callback function to be the sampling function, and can sets the sampling frequency to be at least 128 Hz. Data of each channel of the multiple analog to digital (AD) convertor unit is read by the sampling function according to the preset sampling frequency, and the data is sent to and stored in the buffer memory unit. The record storage flag is regularly sent by the sampling function, and the microprocessor unit (MCU) performs a storage command, reads data from the buffer memory unit, and then sends the data to and stores the data in a preset area of the external data storage card 106. In certain case, if the mobile network terminal device registers with the GPRS mobile network for three times continuously and does not receive the response flag replied from the target server each time, sets the network online flag to be 0 and keeps monitoring the electrophysiological data.
When the electrophysiological data is analyzed and determined to exceed an alert threshold, the mobile network terminal device sets an alarm category flag, and sends an audio alert and/or a vibration alert, a light alert, and a text alert. At the same time, the mobile network terminal device checks whether the network online flag is 1 or not. If the network online flag is 1, the data is packetized, the monitoring data packet is sent, an analysis process suggestion returned from the target server is received, and the network data information exchange is completed. Thus, the mobile network terminal device goes into a status for selecting to exit the electrophysiological data monitoring. If exiting the electrophysiological data monitoring has not been selected for several seconds, the electrophysiological data monitoring proceeds automatically. Otherwise, the work flow is ended. In addition, if the network online flag is 0, the network is not in a connection status, and the mobile network terminal device registers again to establish a connection, sends a monitoring data packet, and receives the analysis process suggestion returned from the target server. If the mobile network terminal device registers with the GPRS mobile network for three times continuously and does not receive the response flag replied from the target server each time, a network connection failure flag is set, and the user is prompted that the network connection is failed. During the electrophysiological data monitoring, the user can end the monitoring work flow by pressing the exit key.

The mobile network terminal device proceeds into the electrophysiological data special monitoring work status 230b, turns off the power supplies of the voice module 105 and the radio frequency antenna unit of the GPRS baseband processor module 100 according to the work mode flag. Meanwhile, the mobile network terminal device sets the interrupt frequency of the timer unit GPTn to be an integer power of 2, sets the interrupt callback function to be the sampling function, and can sets the sampling frequency to be at least 128 Hz. Data of each channel of the multiple analog to digital (AD) convertor unit of the GPRS baseband processor module 100 is read by the sampling function according to the preset sampling frequency, and the electrophysiological data is sent to and stored in the buffer memory unit. The record storage flag is regularly sent by the sampling function, and the microprocessor unit (MCU) performs a storage command, reads data from the buffer memory unit, and then sends the data to and stores the data in a preset area of the external data storage card 106. When the electrophysiological data exceeds an alert threshold, the mobile network terminal device sets an alarm category flag, and sends a vibration alert and/or a light alert, and a text alert, so as to prompt the user to operate the keyboard module 102 and activate the network data communication function. The mobile network terminal device activates the radio frequency antenna unit of the GPRS baseband processor module 100 according to the instruction sent by the keyboard of the user, sets the previous network connection count to be zero at the same time, reads the access point domain name APN and the target server IP address stored in the external data memory 107, registers with the GPRS mobile network, establishes a data connection to the target server, sends the local host user flag and the service category request flag. According to the response flag replied from the target server, the mobile network terminal device reads the event data stored in the external data storage card 106, packetizes the data, and makes a data/information exchange over the network. If there is no response from the target server, the mobile network terminal device will increase a network connection count by 1, and determine whether the network connection count is greater than 3. If the network connection count is greater than 3, the user is prompted that a network connection is failed. During the electrophysiological data special monitoring, the user can end the special monitoring work flow by pressing the exit key.
In accordance with one embodiment of the present invention, the power supplies of the voice module 105 and the radio frequency antenna unit of the GPRS baseband processor module 100 are turned off. The mobile network terminal device is in an offline and silent status, which is convenient for the user to use the mobile network terminal device in the occasions such as an air plane flight, a conference, and an inhibition of the mobile device. Therefore, the continuity of the electrophysiological data monitoring can be maintained, and the electrophysiological abnormity of the user in those special occasions can be detected in time.

By the frequency-division sampling function, the sampling frequency of the pacemaker pulse channel is set to be at least 2,048 Hz, and the sampling frequency of the cardiogram signal channel is set to be at least 128 Hz. The multiple analog to digital (AD) convertor unit of the GPRS baseband processor module 100 is activated according to the preset frequency-division sampling frequency by the frequency-division sampling function, and data of each channel is read. The pacemaker pulse data is compressed, and then sent to and stored in the buffer memory unit. The record storage flag is regularly sent by the frequency-division sampling function. The microprocessor unit (MCU) of the GPRS baseband processor module 100 performs a storage command, reads data from the buffer memory unit, and then sends the data to and stores the data in a preset area of the external data storage card 106. Since the amount of the pacemaker pulse data is large, the data is compressed for storage by a corresponding ratio, which reduces the storage space occupied by the data effectively. When the pacemaker pulse data exceeds an alert threshold, the mobile network terminal device sets an alarm category flag, sends an audio alert and/or a light alert, and a text alert, so as to prompt the user to enable a network data communication function by operating the keyboard. The mobile network terminal device activates the radio frequency antenna unit according to the sending instruction sent from the user keyboard, sets the previous network connection count to be zero at the same time, reads the access point domain name APN and the target server IP address stored in the external data memory 107, registers with the GPRS mobile network, establishes the data connection to the target server, sends the local host user flag and the service category request flag, reads the event data stored in the external data storage card 106, packetizes the data, and makes the data/information exchange over the network. If the target server does not make a response, the mobile network terminal device will increase the network connection count by 1, and determine whether the network connection count is greater than 3. If the network connection count is greater than 3, the user will be prompted that the network connection is failed. During the heart pacemaker monitoring, the user can end the heart pacemaker monitoring work flow by pressing the exit key.
In accordance with one embodiment of the present invention, the raising of the sampling frequency of the pacemaker pulse channel can avoid the missing of the pacemaker pulse data. Therefore, it is benefit to make a calculation and an analysis so as to provide the clinic diagnosis by the remote server and clinic doctors. Meanwhile, the power supply of the radio frequency antenna unit is turned off during the heart pacemaker monitoring, which effectively prevents the radio frequency radiation from interfering with the normal work of the heart pacemaker including the automatic cardioversion IDC. The problem that the existing technology can not be used to the heart pacemaker monitoring and the automatic cardioversion IDC monitoring is solved well.
