The present invention relates to a document processing system based on the HL7 standard, and to a document processing system based on the HL7 standard for supporting the generation and transmission of a message according to the HL7 standard.

In general, when a doctor visits a medical institution, the medical staff manages the patient's medical treatment by recording it on paper or storing it on a personal PC.

In large medical institutions, there are multiple departments and departments, and since departments and departments use software developed by different companies according to their characteristics, it is often necessary to share medical information documents between departments. If so, the medical information documents are exchanged for paper.

If metadata is used to share information of different software with the medical department, the metadata only connects two specific softwares, and in order to link more softwares, another module must be added. Also, this problem also occurs among other hospitals.

In addition, new modules must be added in order to share medical information documents of different software, thus consuming unnecessary time and money.

In order to solve this problem, medical information information technology is being actively promoted, including hospital networking and related research.

Health Level 7 (HL7) is a healthcare information standard for networking between healthcare organizations. It is a set of rules that ensures that information is compatible between software applications in different healthcare sectors. It is a trend, and the use of this means that all types of medical services can be used regardless of the type or size of the medical institution. In other words, HL7 is a network standard that can share patient's medical information.

Accordingly, the development of a system that supports the transfer of medical information documents between medical institutions in accordance with the HL7 standard is required.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and provides a document processing system based on the HL7 standard for generating a message in consideration of the characteristics of a medical institution according to the HL7 standard, and supporting the transmission and reception between the medical institutions. There is.

The present invention for achieving the above object is a document processing system connected to the communication network, and transmitting and receiving the HL7 message,

A database for storing at least one HL7 standard message according to the HL7 standard; The HL7 standard message stored in the database includes a document creation module for defining a message by selecting a message required by a specific medical institution and modifying it to match the characteristics of the medical institution.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram showing in detail the configuration of a document processing system according to the present invention.

As shown, the document processing system 100 includes a database 110 for storing at least one HL7 standard medical information document (HL7 standard message) according to the HL7 standard, and a medical institution among HL7 standard messages stored in the database 110. Document creation module 120 to define a message by selecting a message required by the, and modify it to meet the characteristics of the medical institution, verification module 130 for verifying whether the verification metafile conforms to the HL7 standard, documents The control module 140 for transmitting the HL7 message generated by the compose module 120 or performing processing for the received HL7 message and an access module for adding or deleting data to the HL7 message to generate the HL7 message ( 150).

In more detail, the database 110 stores at least one HL7 standard medical information document (HL7 standard message) according to the HL7 standard generated based on medical information. Here, the HL7 standard message is a HL7 standard document format in which medical information on a specific patient is not recorded, which is preferably based on HL7 version 2.x.

The document preparation module 120 extracts a message required by a specific medical institution from the HL7 standard messages stored in the database 110 and modifies the message to match the characteristics of the medical institution.

In addition, the document creation module 120 converts the HL7 message modified for the characteristics of the medical institution into a verification metafile and an access metafile in order to be applied to the verification module 130 and the access module 150. Generation means 121, access code generation means 123 for generating an access module mapped to the HL7 message using the access metafile, and the verification metafile, verification module 130, control module 140 and access module And engine code generating means 125 for generating an HL7 interface engine module using the 150.

The verification module 130 verifies whether the HL7 message conforms to the HL7 standard by using the data of the verification metafile generated by the metafile generating unit 121, and also requires that the HL7 message is required by a specific medical institution. Check whether it is reflected.

The access module 150 generates the HL7 message by recording the medical information data of the specific patient in the HL7 message, or extracts the specific data from the HL7 message received from the control module 140, and parses the HL7 message.

The access module 150 also includes optimization means 152 for removing the portion of the HL7 message that does not hold data.

The access module 150 is associated with a Microsoft Foundation Class (MFC) class, and utilizes the Intellisense function provided by Visual Studio to check the summary of the properties included in each part of the message and to provide data. It allows you to enter. Here, Intellisense features include summary information display or word autocompletion, providing an array of options for easy access to language references, which can be run directly by code editors or directly to retrieve language elements when coding. Without having to close the mode command window, you can find the information you need without losing context, insert language elements directly into your code, and let the user finish typing on behalf of the user.

The control module 140 transmits the HL7 message to the communication network through the TCP / IP protocol, the HTTP protocol, or the SOAP protocol, and generates an event when receiving the HL7 message to process the event.

The HL7 interface engine disclosed in FIG. 1 is a module including a verification metafile, a verification module 130, a control module 140, and an access module 150. The HL7 interface engine is included in an actual program and operated in a medical institution. This module is used to link with the active program. The HL7 interface engine may be implemented as an independent configuration separate from the document creation module 120. In this case, the HL7 interface engine is a system of another medical institution in order to interoperate with a program provided in another medical institution. The access module 150 writes medical information about the specific patient in the HL7 message to generate the HL7 message for the specific patient.

2 to 5 are diagrams illustrating an embodiment of a document creation module according to the present invention, and show an example of a screen displayed on a monitor when a metafile is generated in the document creation module 120.

When the document creation module 120 is executed, information is extracted from the database 110 and a document creation module screen is displayed as shown in FIG. 2, on the left side of at least one message list and messages added by a user according to the characteristics of a medical institution. The child item segment is displayed.

When a specific message item is selected in the message list, detailed information of the selected message is displayed on the right side so that the message information can be modified.

In addition, if a segment that is a lower item of the message is selected, detailed information of the segment is displayed on the right so that the segment information can be modified. At this time, when the table information exists in the segment, it is also possible to modify the table information.

3 is a diagram showing that the metafile generating unit 120 of the document creation module 120 generates the verification metafile and the access metafile. When the metafile generating unit 120 executes the metafile generation, Meta files can be displayed by displaying all events, messages, segments, composites, data elements, tables, and primitives defined in the HL7 standard. To be created.

4 is a diagram illustrating the structure of the verification metafile generated by the metafile generating unit 120. The event, message, and segment are designated as XML tags, and the data inside each tag is separated using a delimiter.

FIG. 5 is a view showing a metafile structure for access generated by the metafile generating unit 120, and is divided into a message structure, a segment structure, a segment group structure, a composite structure, a subcomposite structure, and the like. It is.
