Fig. 1 is a digital home healthcare middleware architecture.
Detailed Description
Referring to fig. 1, the architecture of the service middleware upon which the method of the present invention relies is implemented. The system consists of six-layer structure of a network adaptation layer, a medical data conversion layer, a granularity service component layer, a digital medical service bus, a medical data integration layer and a medical service providing layer. Wherein,
the network adaptation layer is used for encapsulating services according to technical standard protocols of different networks and realizing data network layer interaction among different network medical application systems; the functions of interface adaptation, user interface and API interface provision are provided;
the medical data conversion layer is used for realizing standardized conversion between input or data medical data according to the medical standard library and the conversion mechanism and strategy between the medical standard library and the medical standard library;
and the granularity service component layer is used for classifying services according to granularity and seeking an integration method of the fine granularity component services so as to integrate the fine granularity component services into coarse granularity services and release the coarse granularity services as Web services, thereby reducing the data communication traffic among the systems.
The digital medical service bus is used for completing registration, inquiry, binding and the like of medical related services and message interaction among the services;
the medical data integration layer is established on a transmission mechanism, realizes extraction and insertion of medical data, and simultaneously packages the medical data or forms an analyzable file.
The method for realizing the home medical service and the data integration through the service middleware is further described as follows:
step one, a network adaptation layer encapsulates services according to open technical standard protocols adopted by a telecommunication network, a broadcast and television network and the Internet so as to provide service output which is suitable for different user access interfaces and has standard description formats;
the open technical standard protocol comprises http, Ftp, SMTP, XML, SOAP, WSDL, UDDI, SDH and the like; the network adaptation layer packaging method and the interface can be manually configured or secondarily developed through the reserved API according to the adaptive configuration of the network.
Step two, the medical data conversion layer converts medical information from different systems or services into medical data meeting HL7 standard or DICOM standard and provides the medical data to the granularity service component layer, and simultaneously converts the medical data output by the granularity service component layer into data output consistent with the service source standard; in the integration process of the family medical service, the data conversion from each medical information system is a service with larger workload, and the success or failure of the integration is also determined. Therefore, on one hand, in the design process, the H L7 standard or the DICOM standard which has wide application and is easy to accept is selected as the conversion medium, and meanwhile, the preprocessing before integration is realized through the introduction of the medical data conversion layer, which is beneficial to the wide application of the invention.
Here, the standards of the service sources are constantly changing due to the number of different hospitals integrated or accessed, so the medical standards library of the medical data conversion layer should be a dynamic learning and rich process. The conversion policy may be increased according to the API interface provided by the network adaptation layer.
Step three, the granularity service component layer defines fine granularity service, coarse granularity service and combined service according to the function based on the service and the data quantity sent and received by the service, integrates the fine granularity component service into the coarse granularity service through the integration of the fine granularity component service, and forms Web medical service which can be realized through a network;
the granularity service component layer takes the fine granularity components and the workflow description file as raw materials and provides services for the Web medical service layer; from the perspective of the Web services layer, the logical component layer provides coarse-grained service components. Traffic changes may cause the functionality of the Web service to change. Because the coarse-grained service component is only a logic service component based on the fine-grained service component and the process arrangement, the requirement of function change can be met only by modifying the process configuration file without deeply modifying the function of the source code level.
Step four, the digital medical service bus finishes registration, inquiry, binding, calling, coordination, arrangement of combined service and message interaction of medical service; the method inquires and positions the service according to the request, completes the calling work of the service and realizes the binding among the service source provider, the current service requester and the service provider.
Step five, the medical data integration layer dynamically configures the sharing setting of the database according to the heterogeneous data source structure information and the sharing requirements of each service source to generate a mapping configuration file; automatically extracting shared data from heterogeneous data sources according to the configuration file, and generating the shared data into XML file representation; packing or parsing XML files;
step six, the medical service providing layer interacts with the medical data integration layer, various functional entities in the medical service providing layer respectively realize the management of data views, metadata and users, provide safety guarantee for data integration, optimize the query request of the users, and store the information of the users and the administrator and cache intermediate data by using XML documents; here, the medical service providing layer should have: the management module is used for managing the medical data view, the medical metadata and the user; the management module is used for providing a graphical interface for a manager of the service platform, guiding the manager to establish a uniform data view according to the data relationship between heterogeneous data sources, dividing users, granting the users access rights of the users to different levels of the data view, and providing updating management on metadata so that the middleware can provide support for a new data source in time; the safety management module is used for providing safety guarantee for medical data and service integration, such as authority authentication, authentication on user access authority and authentication on administrator authority; encryption and decryption, namely encrypting data entering and exiting the middleware and encrypting a data view file: and service control, namely monitoring the service operation to ensure the complete execution of the service. The service control part is completed by a service bus, and the other parts are formed by service combinations in a service layer; the data engine module is used for optimizing the query request of the user in the medical data integration process, making a query plan with minimum cost, decomposing the query according to the plan, decomposing the query into the query of a bottom data source, serializing the queries, calling a data source adapter according to the serialization and executing the query; after the adapter returns the query result, the data engine firstly performs necessary screening on the data and then merges the data according to the data association relation defined by the data view; and the storage management module is used for describing the description of the data view by adopting XML, and storing user and administrator information and caching intermediate data by using an XML document.
In summary, the method for integrating digital home medical services and data can add other auxiliary steps to the implementation process of the essential key steps in the implementation of the method for integrating digital home medical services and data, without departing from the core of the invention and falling into the protection scope of the invention.
