Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4: in order to carry out the consultation of doctors of exchanges data ，Wei strange land between heterogeneous medical infosystem, provide possibility, the present invention includes sampling terminal, relay station and expert system; Sampling terminal is connected with relay station, and relay station is connected with expert system; Sampling terminal is transferred to relay station by the medical information of collection, and relay station converts described medical information to the middle medical information of HL7 message form, and relay station is transferred to expert system by medical information in the middle of described.
Particularly, sampling terminal comprises the sample devicess such as electro cardio signal workstation or sphygmomanometer, and relay station forms by special purpose computer is abstract, and expert system consists of the computer of server Ji Qi high in the clouds management; In the embodiment of the present invention, sampling terminal-relay station adopts stelliform connection topology configuration with being connected of expert system, and the required channel quantity of ，Tu1Zhong network topology mechanism is n bar as shown in Figure 1, and SPL-N represents one group of sampling terminal and relay station, and SC represents expert system.Expanding to community and national medical information switching network, is the cascade of a plurality of stelliform connection topology configurations.
In the embodiment of the present invention, sampling terminal is transferred to relay station by medical information, relay station is converted to medical information the middleware form that all can read identification between different medical infosystem, medical information in the middle of described middleware information is, is converted to middleware form process by medical information and comprises as follows:
1), resolve coded data: sampling terminal is passed through wireless technology, transmission packet is in relay station, relay station is preserved application data by the logical relation of message → message section → field → composition → subconstiuent, them, directly in the link manager of relay station, the various foundation classs (as time, wave sequence and annotation sequence etc.) that relay station reads in message deposit in respectively in the multilevel-pointer linked list data structure of message.
By the linked list data structure of traversal message object, by the definition of order of message segment, essential/washability and repeatable order, read the also data structure of verification message object, search the message element of arbitrary appointment, the schema file that uses HL7 to provide redefines data element and institutional framework thereof; The data memory format of HL7 standard code is XML, and how regulation XML document organizes these message elements.The access relation of HL7 message construction process chained list is: travel through a message section chained list in message object, to each message section object, its field array of pointers element of sequential access, to each field, travel through its Repeating Field chained list, to the nested traversal to its composition chained list of each Repeating Field, to each composition nested traversal to its subconstiuent chained list again, until by data and message separator character on schedule hierarchical relationship insert step by step in message character string variable, its nest relation is as shown in Figure 4.
Use XMLBeans to generate XML(extend markup language (eXtensible Markup Language XML)) data manipulation class.XMLBeans is the XML.Java the Bind tool of increasing income that Apache provides, and it can produce XML data element operation " class " according to XMLschema compiling.According to the feature of HL7 standard, each message that sampling system can be obtained, message section, field, data type etc. are written as respectively a concrete class, then take out message, message section, data type structure class interface.
The corresponding conversion of sampled data and HL7 message data content.Because every record of data mainly comprises header file, data file and comment file.Use the language such as Java, therapeutic scheme and medication information can be stored in element clinialTrial, sampled data is stored in wave sequence; In header file, by sample frequency and initial time, represent; Time series and wave sequence are made to corresponding stores processor, under element sequenceSet, the 1st daughter element sequence sequence storage time, the measured value of the 2nd to the 7th element sequence corresponding stored wave sequence.The initial value of attribute value sequence storage time of the daughter element own of time series sequence, the unit of unit sequence storage time; The baseline value of the value property store wave sequence of wave mode sequence sequence daughter element own, unit representation unit; The resolution of the value property store Wave data of another daughter element scale of wave sequence sequence, unit representation unit.And its annotation information is stored in same XML file with an independent element and Wave data, to realize the corresponding conversion of data content.
HL7 message propagation: transmission of messages module major function is to realize the transmission of medical information between multi-user by computing machine/wireless communication networks, guarantee data security simultaneously, maintain secrecy and the high efficiency of data access, this module is by three sub-module compositions: S1), message validation verification: in communication process, first receiving system carries out the checking of message details in phraseological validation verification and MSH message section to the message receiving, if message is by checking, deliver to application program and continue next step processing, otherwise produce a refuse information and return to transmitting system.Message, when validation verification, need to be called the conscientious parsing of HL7 message construction/parsing module and obtain required data element.S2), message queue: the speed of Internet Transmission and the speed of Message Processing are inconsistent often, in order to coordinate the difference between the two, when receiving system is subject to message, first, in memory setting Yi Ge buffer zone, send successively by the principle of first in first out.S3), relay station and expert system for system described in the embodiment of the present invention, Client/Server pattern, adopts TCP/IP and the programming of Winsock socket, realizes reception and the transmission of message.
HL7 message parse is to be application data by the message conversion of standard format: first resolve message character string, take message separator character as sign, define message section, field, composition and subconstiuent in message, the multipole pointer chain list data structure of structure message, then by the traversal to chained list in data structure, search arbitrary data element.
The realization of Database and content search: XML is as a kind of data file layout; itself possesses database function; and can provide the retrieval to each element by XQuery; but consideration wisdom medical treatment platform is shared the service of grade; the standard of protection XML data structure; can consider with other database, as the MySQL application mode that the data, services phase is combined of increasing income, XML data file index to be stored in to MySQL as a data element.The mode of XQuery and MySQL combination is also used in its inquiry.Application data is at expert system data display.
The present invention's terminal of sampling is transmitted packet in the link manager of relay station by wireless technology, feature according to HL7 standard, can be each message that will use, message section, field, data types etc. are all written as respectively a concrete class, take out again message, message section, data type builds class interface, realize the various foundation classs of message, the parsing giving information and construction method, realize the HL7 coding of general data message or the function that HL7 source codec arrives general data, to realize interconnecting of the systems such as the coordinated exchange Middleware implementation of each main body by relay station and hospital HIS, the intercommunication of various medical treatment detection device data interconnection, its producer's product module standardized designs makes its catbird seat in competition, improve family, hospital is the ability of collaborative work between system separately, the feasibility of the raising strange land consultation of doctors etc.
