The present invention relates to an optimized data control server for a many-to-many communication-based emergency medical system.

The emergency medical system is a medical system that is directly connected to the patient's life by initial treatment. In case of emergency patient in medical blind spots such as home, mountain, wallpaper or farming and fishing village, only basic treatment is available in public health center and small and medium hospitals. Require prompt treatment.

 In order to diagnose several specialists in a tertiary medical institution for multiple patients, M-to-M based communication with multiple patients versus multi-specialists is required.

Among existing network technologies, many-to-many connections are broadcast and multicast. Broadcast is not suitable for medical system applications because it supports the same information in one direction only. Since multicast uses UDP (user datagram protocol), an additional control protocol is essential for the stable transmission of medical data, and due to its close relationship with the standardization of IPv6, it is not yet used in practical applications. In other words, the existing multi-connection support is IPv6 based multicast technology. Routers supporting the multicast protocol are not currently used in general commercial networks, and selective security of patient information is not possible in emergency medical systems. Since all data is transmitted based on UDP protocol, reliable transmission is not guaranteed. In addition, it is difficult to manage participants in the center because the right to join or leave multiple connections does not exist in the application layer of the emergency care system, but in the host.

Hereinafter, the configuration and operation of a data server of a multi-many communication-based emergency medical system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is an explanatory diagram for schematically explaining an operation of a data control server of a communication-based emergency medical system according to an embodiment of the present invention. That is, FIG. 1 is a basic structure of a many-to-many communication-based emergency medical system using a data control server, and includes M patient systems 100, a data control server 200, and N doctor systems 300.

The M patient system 100 is basically DICOM (Digital Imaging and Communications in Medicine), which is a standard for four multimedia data: bio signals, high definition video signals, video conference audio and audio signals, and X-ray or digital medical images. Transmit the image signal. This may vary in the number of transmitted data depending on the location of the patient or the environment of use.

The data control server 200 is located at the center of the emergency medical system, and includes N pseudo-systems for data such as bio signals, high-definition video signals, video conference audio and video signals, and X-ray or DICOM image signals from patient systems. To communicate with each other. The data control server 200 includes two control schemes, a first control scheme and a second control scheme. The first control method is a control method when only one doctor needs one patient to receive a service from a data control server, that is, one patient system needs only one doctor system. The second control method is a control method when one patient needs several specialists, that is, when one patient system needs to communicate with several doctor systems. The data control server 200 first checks how many doctors the patient needs to consult and takes the first control method when only one specialist is needed, and the second control method when several specialists are needed. It works according to.

The database server 400 stores patient information data from the data control server 200 and multimedia related data and control information used for transmission in real time.

FIG. 2 is an example of a diagram of a connection between a patient and a doctor system when the data control server of FIG. 1 operates in the first control method, and FIG. 3 is a view for explaining when the data control server of FIG. 1 operates in the first control method. It is also. As shown in FIG. 2, the first control scheme is for a case where M patient systems 100 and N doctor systems 300 are connected to the data control server 200 but mutually independent communication is required.

When the emergency condition of the P1 patient is required consulting the C1 specialist, the P1 patient system 100 requests the service according to the emergency situation to the data control server 200 (1 in FIG. 3).

The data control server 200 receives the status and transmission bandwidth of the P1 patient system and delivers the patient information such as network address, transmission bandwidth information and multimedia data type information of the P1 patient system to the C1 doctor system 300, and the P1 patient system. Request communication with 100 (2 in FIG. 3).

The C1 doctor system 300 adjusts the compression rate and the like so as to enable optimal communication with the P1 patient system 100 and the C1 doctor system 300 determines whether the connection with the P1 patient system 100 is approved. 200) (3 in FIG. 3).

This again applies to the P1 patient system 100 in the reverse order, when the P1 patient system 100 receives confirmation of the connection with the C1 doctor system 300 (4 in FIG. 3), the transmission environment of the C1 doctor system 300 and The compression rate and type of the transmitted data are determined according to the text situation.

After the data control server 200 manages the above negotiation process and the information exchange is completed, the P1 patient system 100 and the C1 doctor system 300 communicate directly without passing through the data control server 200 (Bypass). 3), the P1 patient system 100 and the C1 doctor system 300 transmit the communication network status to the data control server 200 at intervals of 1 minute (6 and ⑦ in FIG. 3). Even if the state of the communication network changes drastically, the data control server 200 enables rapid processing without loss of data.

FIG. 4 is an explanatory diagram for describing an operation when a user switching is required when the first control method of the data control server of FIG. 1 is operated.

When the first control method operates, the data control server 200 may need to switch users in the patient or the doctor because several users are connected in a one-to-one manner. For example, if one patient needs communication with another specialist, or vice versa, another patient needs a different connection with the specialist who is communicating.

In the first case, when one patient needs to communicate with another specialist, as shown in FIG. 4, the P1 patient system 100 disconnects from the C1 doctor system 300 and communicates with the C2 doctor system 300. When requesting a connection (1 in FIG. 4), the data control server 200 notifies the C1 doctor system 300 of the release request (2 in FIG. 4), and stably P1 patient system 100 and C1 doctor system ( The connection of 300) is released (3, 4 of FIG. 4). After the negotiation and connection of the P1 patient system 100 and the C2 doctor system 300 is a process for allowing direct communication is the same as Figure 3 (⑤ ~ 내지 of Figure 4).

In the second case, when another patient needs a different connection with the communicating specialist, that is, when another patient requests a connection to one communicating physician, the communication with the existing P1 patient system 100 is maintained, Use different ports and multiple monitors to enable simultaneous communication.

Since the first control method of the data control server 200 controls direct communication between users, there is an advantage that unnecessary transmission time and processing time can be reduced as compared with communication passing through the data control server 200.

FIG. 5 is an example of a connection diagram of a patient and a doctor system when the data control server of FIG. 1 operates in the second control method, and FIG. 6 illustrates an operation of the second control method in the data control server in FIG. It is also. As shown in FIG. 5, the second control method of the data control server 200 enables integrated control for a case where a patient wants to communicate by connecting to several doctors at the same time. FIG. 6 is a flowchart illustrating a process flow of the data control server 200 for real time simultaneous connection of M patients P1, ..., PM with N physicians C1, ..., CN. The data control server 200 is provided with a priority transmission table characterized by the specialist, and the patient information transmission method to the doctor system 300 applies a multiple copy method.

The most important consideration in the multiple access is to handle the bandwidth change problem occurring in various network environments such as LAN, x-DSL, WLAN, etc. The patient system 100, which is a transmitter of the information, can maximize each bandwidth. It is not a big problem because it transmits to the data control server 200, but if there is a low bandwidth in the pseudo system 300 to be a receiver, serious transmission delay or data loss may occur. Basically, transmitting the patient information to the N pseudo-systems 300 uses a multiple copy method. The problem of various transmission bandwidths was solved from the observation that the data required for N specialists to consult the patient's condition differed depending on the nature of the medical system. For example, a cardiologist would prefer a bio-signal among four multimedia data (bio signals, high-definition video signals, video conferencing audio and video signals, and X-ray image signals). It is required first. Therefore, in the data control server 200 of the present invention, the priority transmission table specialized for the specialist is prepared in consultation with the emergency specialist and the specialist in each field.

Table 1 shows the priority transmission table characterized by the specialist in the data control server 200.

In FIG. 6, there are connection requests from the M patient systems 100, and the data control server 200 confirms the connection and confirms the data type, compression information, size, and transmission bandwidth of each patient system (① in FIG. 6). ). The data control server negotiates with the N pseudo systems 300 to check the classification and the transmission environment. That is, the transmission status of each pseudo system 300 and the kind of the pseudo system 300 for the multi-copy. ) (② in FIG. 6). The transfer table is created in accordance with the transfer tables characterized in the N pseudo systems 300 (3 in Fig. 6). If the bandwidth of each of the pseudo system 300 is larger than the bandwidth of the data transmitted by the plurality of patient systems 100, all the data can be stably transmitted regardless of the transmission table, but the bandwidth of the pseudo system 300 is greatly reduced. Only the priority data given according to the multi-faceted specialist is transmitted according to the bandwidth. It transmits the data of the M patient system 100 (④ in Fig. 6) and communicates with the pseudo system through the transmission table (⑤ in Fig. 6). Then, the patient information data and multimedia related data and control information used for transmission are stored in the database server 400 in real time (6 in FIG. 6).

7 is an example of a connection diagram of a patient and a doctor system when the data control server of FIG. 1 operates. The data control server 200 includes both the first control method and the second control method, and therefore the data control server 200 can operate in the first control method and the second control method, as shown in FIG. 7. For example, when there is a mixture of independent and multiple connections between patient and physician systems, the communication settings are organically adjusted.

The data control server 200 first checks how many doctors a patient needs to consult with, and if only one specialist is needed, communicates by the first control method, and when several specialists are needed. In the second control scheme, the bandwidth of each specialist system is measured and communicated using the multiple copy scheme according to the transmission table. Therefore, the data control server 200 of the present invention has the advantage that the communication can be optimized as well as the user's requirements while minimizing unnecessary transmission delays and processing delays, and can also store data.

The emergency system using the data control server 200 of the present invention transmits each multimedia data using different network protocols to ensure real time transmission and stable transmission at the same time. Table 2 shows the transport protocols selected according to the characteristics of the multimedia data.

High Definition Video Image courtesy (V & A) Vital signs X-ray, DICOM image protocol UDP UDP TCP TCP

 As shown in Table 2, UDP is used when more real-time transmission is required, such as high-definition video signals or video conferencing, and TCP is used when data loss significantly affects medical diagnosis such as biosignals and X-ray images. To ensure that the transfer is successful.

The following describes the configuration of the data transmission partial system of the present invention.

8 is a high-definition camera and videoconferencing transmission sequence diagram of the present invention. It is a flowchart when video conferencing (Video & Audio) is performed through the high-definition camera mounted in the patient system 100 and the doctor system 300, respectively.

When the high quality image data is transmitted from the patient system 100 to the pseudo system 300 (S100), the pseudo system decodes the compressed data (S110) and displays the high quality image (S120).

If the patient system 100 transmits the video conference image data to the doctor system 300 (S130), the doctor system 300 determines whether the received video conference image data is compressed to H.261 or H.263. According to the decoding (S140, S145), a display is performed.

When the patient system 100 transmits the video conference voice data to the doctor system 300 (S150), the doctor system 300 decodes the data compressed by G.711 to perform audio play.

9 is a result of the videoconferencing transmission of FIG. 8. That is, the high definition video image signal and the video conference information transmitted through the data control server 200.

In the present invention, the high-definition camera and videoconferencing data are acquired using two cameras mounted in the patient system 100 and the doctor system 300, respectively. High-definition cameras compress the video using MPEG4 at 640 × 480 resolution. In video conferencing, video data is compressed using H.263 and audio data using G.711.

10 is a biosignal transmission sequence diagram of the present invention.

When the patient system 100 transmits the patient's biosignal information to the doctor system 300, the doctor system 300 checks whether the patient's biosignal is a patient's biosignal (S210) and according to the input biosignal. Electrocardiogram (ECG), oxygen saturation (SPO2), respiratory signal (Resp), blood pressure (NIBP: Non invasive blood pressure) is displayed (S220, S230, S240, S250).

FIG. 11 is an example of a biosignal transmission result of FIG. 10 through a data control server.

The bio signals obtained from the patient monitor of the patient system 100 include electrocardiogram, oxygen saturation, blood pressure, respiration. The ECG signal is designed to selectively check the long section as shown in the transmission result of FIG.

12 is an X-ray and DICOM image transmission sequence diagram of the present invention.

If the patient system 100 transmits an X-ray, DICOM image file to the pseudo system 300 (S300), if the DICOM image is stored in the database server 400 in accordance with the DICOM standard and other image files are also stored in the database server 400 Store in (S310, 320).

 The patient system 100 transmits control information to the doctor system 300 (S330), and the doctor system 300 checks whether there is an image to be controlled among the stored files (S340), and the file to be controlled is a DICOM image. If the file is a DICOM image file is displayed (S350), and if the file to be controlled is not a DICOM image file but another file, the other file is displayed (S360).

FIG. 13 is an example of an X-ray and DICOM image transmission result of FIG. 12 through a data control server.

X-ray images are acquired in accordance with the DICOM standard at PACS, an in-hospital information system. Emergency medical systems acquire and transmit radiographic images through an interface that is compliant with DICOM standards.

The following describes the configuration of the data control server partial system of the present invention.

FIG. 14 is a direct connection sequence diagram of a first control method of the data control server of FIG. 1.

The patient system 100 first requests a connection to the data control server 200 (S400), and the data control server 200 confirms whether or not the patient can join (S410) and approves the connection, and the patient system in the patient information list. IP information and port information of the 100 are stored (S420). The patient system 100 then transmits the patient information to the data control server 200 (S430). That is, the patient system transmits the type and information of the data to be transmitted. The data control server 200 stores patient information in the control monitor (S440). After that, we wait for consulting of the doctor system.

The doctor system 300 also requests connection to the data control server 200 (S450), and the data control server 300 checks whether the doctor is a joinable doctor (S460), and if the doctor is a joinable doctor, the patient in the doctor system 300. In response to a request for information (patient IP, port, etc.) (S500), the data control server 200 transmits a patient information list (patient IP, port, etc.) to the pseudo system 300 (S510).

The doctor system 300 checks whether the patient is a patient who meets the characteristics of the doctor's specialty from the patient information, that is, the doctor wants to connect to the patient, and adjusts the compression ratio to allow optimal communication with the patient system (S520). In this case, the doctor system 300 adjusts the compression ratio and the like so as to enable optimal communication with the patient system 100, and the doctor system 300 grants the approval of the connection with the patient system 100 to the data control server 200. If the patient system 100 receives the connection approval with the doctor system 300 through the data control server 200, the compression rate and type of the transmission data according to the transmission environment and the professional situation of the doctor system 300 Determine.

The doctor system 300 requests a connection to the patient system 100 (S530). As a result, the doctor system 300 establishes a direct session with the patient system 100. That is, the patient system side creates a server socket for listening to the pseudo system after listening to the data control server, and is listening.

The patient system 100 notifies the doctor system 300 that the connection is successful (S540), and transmits patient information to the doctor system 300 (S550). The patient data transmitted at this time is an image signal file such as a high quality video image signal, a video conference image and audio signal, a biosignal such as an electrocardiogram or a respiratory signal, a DICOM image or other images.

The doctor system 300 sends the specialist data to the patient system (S560). This specialized data is an image signal file such as video conferencing video and audio signals, DICOM images or other images.

FIG. 15 is a multiple connection sequence diagram of a second control method of the data control server of FIG. 1.

The patient system 100 first requests a connection to the data control server 200 (S400), and the data control server 200 confirms whether or not the patient can join (S410) and approves the connection, and the patient system in the patient information list. IP information and port information of the 100 are stored (S420). The patient system 100 then transmits the patient information to the data control server 200 (S430). That is, the patient system transmits the type and information of the data to be transmitted. The data control server 200 stores patient information in the control monitor (S440). After that, we wait for consulting of the doctor system.

The pseudo system 300 also requests a connection to the data control server 200 (S450), and the data control server 300 checks whether the doctor is a joinable doctor (S460), and if the doctor is a joinable doctor.
