Field of the Invention [0002] The present invention relates to a medical device monitoring apparatus, and more particularly, to a medical device monitoring apparatus connected to a plurality of medical apparatuses and a hospital information system to perform monitoring on the medical apparatus.

Due to the development of information and communication, computer-based patient records have become commonplace in the medical field. Such medical information includes personal medical information such as family history, past history, and mental illness records as well as visual information such as X-ray.

Representative systems for processing and managing such medical information include an electronic medical record (EMR) system and a facsimile (Picture Archiving and Communication System: PACS). The EMR system includes medical record such as admission record, outpatient initial record, outpatient record, problem list, progress record, surgery / anesthesia record, discharge summary, consultation medical record and special treatment record, prescription execution linkage record, Nursing records such as observation record, special measurement record, nursing process, discharged nursing record, surgical nursing record and restoration nursing record, record of the patient's basic information and patient record such as patient reception information, It is a system that can integrate all the information about the patient without chart (chartless) by constructing the prescription record such as injection prescription, examination prescription and treatment / surgery prescription as an integrated database (DB).

Therefore, EMR is able to reduce the chart management cost, labor cost, various printing expenses, etc. by computerizing without medical chart, medical care, nursing, prescription, It provides intervention to prevent medical accidents, improve efficiency of medical treatment and reduce redundant tasks, and to work efficiently and manage various statistics.

Fax (PACS) is an image storage and transmission system that stores and manages medical images photographed without film (filmless) as digital data, which is required in analog imaging medical devices such as conventional X-ray and CT. This PACS eliminates the cost of film management and film purchasing because the film is not needed, and it can improve the efficiency of the medical treatment because the medical image can be seen and diagnosed everywhere.

However, the conventional EMR has a problem in that it can not interoperate with the test information measured in a plurality of medical devices having various data interface standards, only by computerizing the text-based information recorded by the medical staff, the nursing staff, . That is, a plurality of medical devices have different data interface standards, and thus can not be interworked with the EMR system.
