The diagram schematically depicts the functional blocks made by the client end and the monitoring end. In addition to the circuit-based functional modules, some portions of the module may be embodied by software or firmware. In an exemplary embodiment, a monitoring server 49 may be installed at the monitoring end. The monitoring server 49 is such as a computer server that is installed within a LAN.

A user interface initiated by the monitoring program is used to guide the user to perform authentication, message acquirement, and monitoring physiological signals.
The monitoring server 49, over the first network, connects with the at least one physiological sensing device at the client end for acquiring the physiological signals. While the monitoring server receives the request made by the medical staff who uses the monitoring terminal device 42 for accessing the messages, the server may permit the staff's access request for the client's data according to his privilege. In which, the monitoring program converts the physiological signals to the understandable monitoring messages. The user interface initiated by the monitoring program therefore displays the monitoring messages. The messages may be made to describe any abnormal condition, for example using video, pictures, or lighting. The monitoring program not only allows the staff to access the physiological signals stored in the monitoring server 49, but also to acquire the latest signals instantly for real-time monitoring.
Further, the monitoring terminal device 42 and the monitoring server 49 may be within the same LAN; or alternatively located in different network domains. Over the mentioned second network, the monitoring terminal device 42 is connected to the monitoring server 49. The monitoring terminal device 42 is such as a computer system having a data process unit 421 that is used to process the physiological signals obtained from the monitoring server 49 to be the monitoring information. The data processing unit 421 is a core circuit of the monitoring terminal device 42 in charge of data processing including the signals useful to the present invention.

The input module 423 includes the inside circuit for processing input signals, and an input interface such as the touch-sensitive display, tangible keyboard, computer mouse, or a gesture sensor.
In addition to the physiological sensing devices 47, 48 at the client end, the user at the client end may also use a mobile communication device 40 such as mobile phone, smart phone, or tablet computer. In particular, the mobile communication device 40 is provided for the user to transmit the physiological signals when the user puts on the portable physiological sensing device(s). Through this mobile communication device 40, the user is allowed to communicate with the medical staff at the monitoring end.
The mobile communication device 40 has built-in communication function, for example the communication unit 403 is activated to establish connection to the network 4.

Over the network 4, the medical staff at the monitoring end is allowed to communicate with the end user by vocal or video call. The mobile communication device 40 may include a video-audio processing unit 401 that is used to process the audio/video signals there-between. In one embodiment, a notification technological may be adopted to conduct the message transmission. For example, the monitoring terminal device 42 transmits messages to the mobile communication device 40 at the client end using a notification message.
In one further embodiment, the mobile communication device 42 may be disposed with a positioning unit 402 for acquiring position thereof. The positioning unit 402 is such as the circuit components of a Global Positioning System (GPS). The positioning unit 42 acquires the device's positioning information that is transmitted to the monitoring end. When the monitoring staff obtains the client's position, any location-based assistance may be provided if any emergency is met. For example, the nearby hospital may be recommended based on the positioning information.
According one of the embodiments of the present invention, a monitoring program is initiated to establish connection with the monitoring server when the medical staff uses the monitoring terminal device to access the client's physiological signals. Then the monitoring server generates a request of ID verification for confirming the staff's privilege to use the monitoring terminal device. The verified ID is allowed to access the subscriber's data. In the meantime, it determines the clients to be monitored when the privilege associated with the medical staff's ID is verified. The medical staff may be permitted to access multiple clients' data and as well to monitor multiple clients.
The client's data may include the each client's ID and the associated physiological signals. The physiological signals include signals instantly obtained from the client end. The signals may also be the monitoring data collected within a period of time for the purpose of diagnosis. The signals may be the accessible history. Those data may be stored and updated in or link to the subscriber database of the monitoring server. Furthermore, the medical staff may modify the diagnosis or give annotation to the content.
It is noted that the monitoring program installed in the monitoring terminal device may be configured to determine the abnormal signals from the physiological signals according to a preset warning threshold. In addition to creating records, the monitoring program is activated to transmit message to the client end. The mentioned notification is one of the methods to conduct the messaging. The medical staff may also therefore decide the method to communicate with the user at the client end. At last, the content may be updated to the database when the medical staff makes diagnosis. It is noted that the process of updating database never ends until all the physiological data are completely checked.
In one further embodiment, when the person to be monitored under the telemedicine information system is a patient who is bedridden in bed, he or she may wear the wearable physiological sensor for a period of time; the physiological sensor may periodically send the physiological data as the sensor is always on line. The monitoring end therefore periodically receives the message from the client end. Any medical decision can be made if any abnormal condition is checked.
In one further embodiment, the person to be monitored may wear the physiological sensor at the moment he/she feels unwell since the physiological sensor is not always put on. Therefore, the physiological data may be generated and sent to the monitoring end at the moment the person put on the sensor. The person to be monitored may activate a communication with the medical staff as he requires. The medical staff at the monitoring end may clearly check the medical data associated with the retrieved physiological data through his/her handheld monitoring terminal device. The staff may provide location-based medical advice to the person, or/and establish a communication channel to the client end. The advice is such as teaching any person at the client end to handle the emergency, or to take medicine. In an exemplary example, multiple medical staffs may simultaneously in consultation over a voice call or video call as a conference call. A suitable nearby hospital may be advised when the monitoring end can position the person to be monitored.

If any abnormal condition is found by the monitoring end, the communication set 517 is utilized to communicate with the remote medical staff over a voice call, video call or by texts. In one further embodiment, the positioning circuit in the communication set 517 assists the monitoring end to recognize the person's location since he/she is permitted free to walk or go out. The positioning function allows the medical staff anytime to acknowledge the person's location. It is also convenient that the monitoring end sends staff to the site if any abnormal condition is checked. Any location-based medical advice may also be provided if the person needs.
In one embodiment, the communication set at the client end is such as a smart phone or tablet computer. The program at the monitoring end is allowed to send a navigation map to the communication set at the client end according to the positioning data. Therefore, the person at the client end may accordingly find the help in accordance with the navigation map.
At the monitoring end, the servers and devices are within a local network 55. The server at the monitoring end is such as a monitoring server 551 used for retrieving physiological data from the client end. A subscriber database 553 at the monitoring end is used to store and record information of the client end. A wireless station 555 is introduced to the system for rendering wireless communication service for the monitoring terminal device 557. The device 557 is therefore allowed to wirelessly access the monitoring server 551 and the subscriber database 553.
In this architecture of telemedicine information system, the client end may be accessible to the monitoring end over the network 50 in addition to the traditional telecommunication. Over the network 50, the both sides may be conducted with voice or audio/video call if any abnormal condition is found. The mentioned notification may be incorporated to this system of notifying message over the network 50. In an exemplary embodiment, a user interface may be initiated by the program operated in the monitoring terminal device 557, and used to display the message onto the screen of the device 557. The user interface may also guide the user, e.g. the medical staff, to operate the system, including network connection, retrieval of the physiological data, and the communication made to the client end. Besides the software program installed in the communication set, a program add-on in web browser or any specific web site may serve the foregoing functionalities.
In one embodiment of the system, a message server 531 is installed. This message server 531 renders the function of transferring messages. For example, the message server 531 may render the above-mentioned service of notification, by which the messages are transferred to the corresponding client end. While the message server 531 serves as an email server, the messages are the electronic mails. While the message server 531 conducts the short message service (SMS), the message server 531 may be a simple message service server.
This figure depicts the user interface of the monitoring terminal device. When the monitoring terminal device is utilized to retrieve client data associated with one or more client ends from a monitoring server, one or more monitored items 603 of the every client end may be displayed according its corresponding identification code 601. For example, the monitored items corresponding to the identification code 1 provided by the system are such as heart rhythm and blood pressure.
