Study On The Integration Of ECGs Devices In Digital Hospital Based On Service Oriented Architecture

Digital is an important tool for hospital, and it can improve services and benefit, Optimize management pattern and work flow. As the degree of digital information deeps and the requirement of medical data sharing increases, the integration of medical devices and information systems gradually became popular in digital treatment. Digital hospital involves the integration and share of amounts of medical data. For the device integration, now the general solution is case-by-case access or small-scale interoperation by system integrator or provider according to the detailed requirement, this solution results in Information Islands and influences the depth and extent of information sharing. For the information system integration, the standardization of information system in many hospitals fall behind and it makes the effective integration between systems become impossible.Electrocardiogram (ECG) is one of the three routine examinations in hospital. Because of the complex ECG information, covering all ECG information is almost impossible. Moreover, information systems are divided vertical by their function in departments. ECG devices apply in many department, and it maybe need to integrate with different information systems. Even the same information may be expressed by different formats. Now there are many standards of electrocardiogram data format and it is a great disadvantage to the integration and share.Based on the deep research of a Medical Device Integration Framework based of SOA and analysis of requirement of ECG devices, this paper first propose a solution about the integration of ECG devices in that framework. We take the 12 leads ECG devices as a virtual device, design how it works. Virtual devices can shield the complexity of physical devices and improve efficiency of devices integrating in the digital hospital. This paper also implements design a data gateway which implement any kind of mutual conversion of SCP-ECG, FDA XML ECG and DICOM ECG.At last, this paper gives an application of ECG data gateway in the experimental system of core platform of digital hospital, and received a favorable feedback.
