  • A variety of medical devices have evolved throughout the years. Commonly used devices have typical radiological appearances which are familiar to radiologists. However, some new devices, as well as devices that are not commonly used, may be missed or misinterpreted by radiologists. It is even more difficult to identify a certain medical device with limited clinical history. Therefore, accurate identification of medical devices is crucial to diagnose malposition and potential complications. In this article, we provide a pictorial review of medical devices of the abdomen and pelvis according to classifications that include gastrointestinal devices, hepatobiliary devices, genitourinary devices, and miscellaneous. We also comprehensively review the clinical and radiologic features of complications related to these medical devices.

  • Purpose: The purpose of this study is to find out the cognizance of medical device safety information (MDSI) monitoring in the hospital and oriental hospital workers, and the different aspect of MDSI between oriental medical devices and medical devices. Methods: The survey was performed both in the oriental medicine hospital and general hospital. The survey had 16 items; 2 items basic questions, 5 items in the awareness of MDSI, 5 items in the education of MDSI, 4 items in the necessity of defining oriental medical devices and differences between general and oriental medical devices. A total of 120 hospital worker were participated; 60 oriental medicine hospital workers and 60 general hospital workers. They had worked in the oriental medicine or general hospital associated with 'Medical Device Safety Monitoring Center, Dongguk University Ilsan Hospital' in 2019 and 2020. Results: The cognizance of MDSI was high both in oriental medicine hospital and general hospital workers and there were no significant differences between oriental medicine and general hospital workers. When we divided the hospital workers into the senior workers who had worked for over 3 years and junior workers for less than 3 years, the senior workers had higher awareness of MDSI than junior workers. However, the cognizance of education of MDSI was high which was not different between senior and junior workers. Both hospital workers thought that it was necessary to define oriental medicine device legally and the oriental medical device might have low risk and less side effect than medical device. Conclusion: The cognizance of MDSI was high and there was no significant differences between oriental medicine and general hospital workers. Because the senior hospital workers had higher recognition of MDSI, we need to provide the continuous education program for junior hospital workers. Although oriental medical device are thought to be safer than medical device, we need to have a legal definition.

  • Medical Gateway(MG), that integrates medical devices with its unique data format in various hospital information systems, provides effectiveness in the cost of the management unlike existing systems that uses PC as a gateway to hospital information systems because MG enables to interface medical devices with itself. However, in spite of using MG for integrating medical devices, we need additional programs or systems to interwork with EMR system of each hospital in accordance with the configuration of DB. In this paper, we design and implement the format of medical information and server system for interworking MG with EMR system. The proposed system makes easy exchanging medical data between MG and EMR system. Thus, the proposed system can contribute to a national project to export abroad advanced hospital setup converged with IT.

  • Recently, many of hospitals have hurried to computerize the resulting data from medical devices, in order to introduce Electric Medical Record(EMR). In terms of the linkage between medical devices and hospital information systems, however, many difficulties have arisen due to some reasons such as the variety of prescription input, the format difference of the resulting data sheet, and the interface difference between medical devices from different companies. To solve these problems, many researches on standardization of the resulting data of medical devices have been performed. In this study, the linkage between hospital information systems and resulting datum in Electrocardiogram(ECG) generating biosignal waveform was tested by applying Medical waveform Format Encoding Rules(MFER) Version 1.02, which has more advantages than existing global standard. MFER viewer, in addition, was made to display the resulting data on a screen. The MFER viewer was tested and compared to the existing Scalable Vector Graphics (SVG) Viewer. The results showed that this method is more effective in the interface the data storage and application, because of simplicity and easiness in data applications. And the results show that the MFER is convenience and effective for physician. It is considered that the role of MFER as the interface in biosignal waveform including Electrocardiogram medical devices would expand in the near future.

  • This exploratory study aimed to explore the perception (knowledge and attitude) and behaviors of medical personnel regarding medical device safety and to identify the differences in results linked with the type of their task. A questionnaire was administered to medical personnel working at a tertiary care hospital with 900 beds in Incheon, Korea, and 220 completed questionnaires were used for analysis. The results revealed that the majority of the medical personnel perceived the potential risk involved in different types of medical devices they use and stated that they need training programs for safe use of medical devices. Concerning the perception regarding medical devices across different positions within the hospital, it was found that the residents had a low awareness about safety issues, although the medical services they handled involve high risks, thereby calling for safety training. Further nationwide studies are needed to improve the quality and validity of data and eventually to provide important information required by policy makers and academicians to manage medical device safety.
