Abstract

PROBLEM TO BE SOLVED: To transmit maximum information according to a character set usable on a transmission destination device.SOLUTION: A medical information management server receives retrieval conditions and character set information from a client terminal (step S13), and acquires one or multiple groups (groups of single byte characters, ideographic characters, and phonograms) contained in the character set of the client terminal (step S14). Then, the medical information management server searches for a patient matching the retrieval conditions (step S16), and extracts the patient's name (single byte characters, ideographic characters and phonograms) represented by characters corresponding to the groups contained in the character set of the client terminal (step S17). Then, the medical information management server converts the character codes for the patient's name from the character set in the medical information management server to the character set of the client terminal (step S18), and transmits the patient's name with the converted character codes to the client terminal (step S19).

Description

  The present invention relates to a data transmission device and a data communication system.

  In general, in a system that handles medical information, a usable character range (character set) is defined for each system. A character set is a set of characters defined by international and industrial standards. The types of character sets are ISO_IR 6 (ASCII characters + symbols), ISO_IR 100 (Latin 1 (Western European characters)), ISO_IR 101 (Latin 2 (Eastern European characters)), ISO_IR 13 (Roman characters + half-width kana), ISO 2022 IR 87 (First level kanji + full-width kana), GB18030 (simplified kanji + general East Asia), ISO_IR 192 (Unicode), and the like.

  In the medical information system, many person names are managed by single byte characters (Singlebyte), ideographic characters (Ideogram), and phonetic characters (Phonogram). Depending on the settings at the time of shipment or installation of the system, in each system, a person name such as a patient name is displayed by a display method corresponding to the character set.

  8A to 8D show examples of conventional display of person names. As shown in FIG. 8A, in a system in Japan, a person name is displayed as a single byte character (ASCII character), an ideogram (kanji), or a phonetic character (kana). As shown in FIG. 8B, in a system in the European Union, a person name is displayed with single-byte characters and phonetic characters (Latin extended characters). As shown in FIG. 8C, in the system in the United States, a person name is displayed with single-byte characters. As shown in FIG. 8 (d), in a system in China, a person name is displayed with single-byte characters and ideograms.

  In operation for each medical facility, systems that can handle the same character set are usually connected. For example, the character set usable in the A system is “ISO_IR 6”, the character set usable in the B system is “ISO_IR 13” and “ISO_IR 6”, and the character set usable in the C system is “ISO_IR 13”. ”, The A system and the B system can be connected by“ ISO_IR 6 ”, and the B system and the C system can be connected by“ ISO_IR 13 ”, but the A system and the C system can be connected. Can not.

  Thus, conventionally, communication between the same character sets has been mainstream. However, in recent years, as devices and systems in medical facilities become multi-vendor, unified management of images and character information for devices and systems that handle different character sets is required. In facilities where a wide variety of systems coexist, it is necessary to perform data communication between systems with different character sets even if the information is somewhat degraded.

  For example, by using the smallest character set (for example, ASCII characters) described in product specifications, it is possible to exchange the minimum amount of data, or exchange information by masking part of information according to the communication partner. The method to take is taken.

  In the character information management server, the patient ID is associated with the patient name represented in advance by a single byte character (ASCII character), an ideogram (kanji), and a phonetic character (kana / kana), A character information inquiry system that transmits a patient name in a character type requested from a client terminal based on a patient ID has been proposed (see Patent Document 1).

[Operation of each device in medical information communication system]
Next, the operation in the medical information communication system 100 will be described.
FIG. 5 is a ladder chart showing a patient name registration process executed in the medical information management server 10 and the client terminal 20a. The processing in the medical information management server 10 is realized by software processing through cooperation between the control unit 11 and a program stored in the storage unit 15. Further, the processing in the client terminal 20a is realized by software processing in cooperation with the control unit 21 and a program stored in the storage unit 25.

  First, in the client terminal 20a, the user inputs the patient name from the operation unit 22 using single-byte characters (for example, ASCII characters), ideographic characters (for example, kanji), and phonetic characters (for example, kana) (step S1). And the input patient name is acquired by three types of characters by the control part 21 based on the operation signal from the operation part 22 by a user's operation.

  Next, the control unit 21 generates a patient name represented by single-byte characters, ideograms, and phonetic characters, and character set information indicating a character set that can be used by the client terminal 20a read from the storage unit 25. Then, it is transmitted to the medical information management server 10 via the communication unit 24 (step S2).

  In the medical information management server 10, the control unit 11 receives the patient name and character set information transmitted from the client terminal 20a via the communication unit 14 (step S3).

  Next, the control unit 11 refers to the character code correspondence table 152 based on the character set information received from the client terminal 20a, and from the character set “GB18030” of the client terminal 20a to the character set “ISO” of the medical information management server 10. The character code of the patient name (single byte character, ideogram, phonetic character) received from the client terminal 20a is converted into “2022 IR 6” and “ISO 2022 IR 87” (step S4).

And the patient name after character code conversion is memorize | stored in the patient information D1 of the memory | storage part 15 by the control part 11 (step S5). For example, “TANAKA ^ RAIKA” as a single byte character, “Tanaka ^ Kiraka” as an ideographic character, and “Tanaka ^ Leica” as a phonetic character are stored in the patient information D1 of the storage unit 15.
This completes the patient name registration process.

Similarly, registration processing is performed for patient information D1 and examination information D2 other than the patient name. Moreover, it is good also as inputting and registering patient information D1 and test | inspection information D2 from the operation part 12 of the medical information management server 10. FIG.
The patient name registration process may be performed from the client terminals 20b and 20c, but it is desirable to perform the patient name registration process from an apparatus that can use a character set including all single-byte characters, ideograms, and phonetic characters. .

  FIG. 6 is a ladder chart showing a patient name search process executed in the medical information management server 10 and the client terminal 20a. The processing in the medical information management server 10 is realized by software processing through cooperation between the control unit 11 and a program stored in the storage unit 15. Further, the processing in the client terminal 20a is realized by software processing in cooperation with the control unit 21 and a program stored in the storage unit 25.

  First, in the client terminal 20a, the user inputs search conditions such as a patient ID and an examination date from the operation unit 22 (step S11). Then, the input search condition is acquired by the control unit 21 based on an operation signal from the operation unit 22 by a user operation.

  Next, the control unit 21 sends the search condition and the character set information indicating the character set usable by the client terminal 20a read from the storage unit 25 to the medical information management server 10 via the communication unit 24. It is transmitted (step S12).

  In the medical information management server 10, the control unit 11 receives the search condition and character set information transmitted from the client terminal 20a via the communication unit 14 (step S13).

  Next, the control unit 11 refers to the character set-group correspondence table 151 based on the character set information received from the client terminal 20a, and one or a plurality of groups (single-byte characters) included in the character set of the client terminal 20a. , Each group of ideograms and phonetic characters) is acquired (step S14).

  Next, the control unit 11 refers to the character code correspondence table 152 based on the character set information received from the client terminal 20a, and from the character set “GB18030” of the client terminal 20a to the character set “ISO” of the medical information management server 10. The character code of the search condition is converted into “2022 IR 6” and “ISO 2022 IR 87” (step S15).

  Next, the patient information D1 and examination information D2 in the storage unit 15 are referred to by the control unit 11, and a patient corresponding to the search condition is searched (step S16). For example, when a patient ID is input as a search condition, information corresponding to the input patient ID is searched from patient information D1 and examination information D2. When an examination date is input as a search condition, information corresponding to the entered examination date is retrieved from the patient information D1 and the examination information D2. And the patient name (single byte character, ideogram, phonetic character) represented by the character corresponding to the group acquired by step S14 is extracted from the patient information D1 by the control part 11 (step S17).

  Next, the character code correspondence table 152 is referred to by the control unit 11 and extracted from the character sets “ISO 2022 IR 6” and “ISO 2022 IR 87” of the medical information management server 10 to the character set “GB18030” of the client terminal 20a. The character code of the patient name thus converted is converted (step S18). And the patient name after character code conversion is transmitted to the client terminal 20a by the control part 11 via the communication part 14 (step S19).

In the client terminal 20a, the patient name transmitted from the medical information management server 10 is received by the control unit 21 via the communication unit 24 (step S20). Then, the patient name (single byte character, ideogram, phonetic character) is displayed on the display unit 23 by the control unit 21 (step S21).
This completes the patient name search process.

As described above, the case where the medical information transmitted from the medical information management server 10 to the client terminal 20a is the patient name has been described. However, a person name other than the patient name, such as a doctor name, a nurse name, and an engineer name, may be used. Further, these person names may be included in the accompanying information attached to the image file.
Also, the medical information management server 10 and the client terminals 20b and 20c perform the same process as the patient name search process shown in FIG.
