The present invention relates to a medical information conversion device, which is characterized in that after a conversion device is electrically connected to at least one medical device, the interface format of the medical device is read by using an interface comparison module, and then at least one comparison database is used. Extracting a data record format that conforms to the format of the user interface, and using a data capture module to retrieve the information required by the user from the interface format, and obtaining the relevant subject by the identity recognition module The information is finally generated by a conversion module integrating the information of the interface comparison module, the data acquisition module and the identity recognition module to generate a relay conversion information. In this way, the messy data can be retrieved from each medical device, and the format can be automatically converted after being integrated with the identity identification data, thereby facilitating the transfer, reading and storage of the data.本新型為有關一種醫療資訊轉換裝置,主要係將一轉換裝置電性連結至少一醫療設備後,利用一介面比對模組讀取該醫療設備之使用介面格式,接著由至少一比對資料庫中提取一符合該使用介面格式之資料記錄格式,並利用一資料擷取模組由該使用介面格式中擷取使用者所需之資料,且可透過一身分辨識模組取得受測者之相關資料,最後以一轉換模組整合該介面比對模組、該資料擷取模組及該身分辨識模組之資訊而產生一中繼轉換資訊。藉此,可從各醫療設備擷取凌亂的資料,並得與身分識別資料整合後自動轉換格式,而方便資料的轉傳、讀取、儲存。
