1、AbstractTelemedicine systems have become an important supporting for the medical staffs. As the development of the mobile phones, it is possible to apply the mobile phones to be a part of telemedicine systems. We developed an innovative Remote Patient Monitoring System using a Java-enabled 3G mobile
2、 phone. By using this system, doctors can monitor the vital biosignals of patients in ICU/CCU, such as ECG, RESP, SpO2, EtCO2 and so on by using the real-time waveform and data monitoring and list trend data monitoring functions of installed Java jiglet application on the mobile phone. Futhermore, d
3、octors can check the patients information by using the patient information checking function. The 3G mobile phone used has the ability to implement the application as the same time as being used to mak a voice call. Therefore, the doctor can get more and more information both from the browsing the s
4、creen of the mobile phone and the communicating with the medical staffs who are beside the patients and the monitors. The system can be conducted to evaluate the diagnostic accuracy, efficiency, and safety of telediagnosis.I. INTRODUCTIONHE rapid development of information and telecommunication tech
5、nology has brought great revolutions in our everyday lives. The impact to medical field is being felt with many new applications using these technologies. Telemedicine is essentially the use of both information technology and telecommunications to provide health services or support health service pr
6、ovision over a distance. Telemedicine systems can be devided into two fields: one is that the mobile devices are used by patients to measure the medical data of themselves. For example, the European EPI- MEDICS project has developed a Personal ECG Monitor having the capabilities of recording ECG at
7、anywhere and anytime 2. A Peak flow monitoring system via a mobile phone for asthma is developed in UK5. The other field is that the mobile devices are used by medical staffs as an assistant for their daily work. A paramedical system has been developed using PDA to get efficient medical information
8、in India1.TDuring the past decade, several new kinds of mobile devices, such as PDA, mobile phones and some intelligentPu Zhang, Yuichi Kogure, Hiroki Matsuoka, Masatake Akutagawa, Yohsuke Kinouchi are with the Institute of Technology and Science, the University of Tokushima, Tokushima, 770-8506, JA

(corresponding author to provide phone: +81-88-656-7576; e-mail: zhangpuee.tokushima-u.ac.jp) Qinyu Zhang is with ShenZhen Graduate School of Harbin Institute of Technology, ShenZhen, Chinaand wearable medical devices have been designed. Combined to the recent proliferation of wireless communic
10、ation solutions, this provides new development opportunities for telemedicine. However, there are some inherent limitations of mobile devices, such as memory capacity, CPU speed, small screen area, etc. These make internet access from mobile devices more difficult as compared to that from desktop co
11、mputers. In Japan, mobile phone is recognized as “Ubiquitous service platform”. The total number of the subscribers of mobile telephone(including PHS) is about 95 million. The big market is shared by three carrier companies. More than 52 million users belong to NTT DoCoMo Inc., while over 27 million
12、 users belong to KDDI Corporation, and about 15 million users belong to SOFTBANK Corporation(as of January 31, 2007, according to Telecommunications Carriers Association, Japan). The statistic data mean that almost each person in Japan has a mobile phone in hand. In another aspect, the mobile phones
13、 have become more and more powerful. Although remain small screen size of the mobile terminals, the functions, such as memory capacity, CPU speed, Java-enabled applications and camera performance are continuously getting improved. Futhermore, third- generation(3G) mobile communication networks(WCDMA
14、) combine standardized streaming with a range of unique services to provide high-quality Internet contents. The phone is possible to transfer large amount of data, such as photos, movies and application files etc, because of its wide transmission band. This paper presents a novel Remote Patient Moni
15、toring System for doctor. By using a 3G mobile phone, the doctor can monitor the realtime biosignals of patients in ICU/CCU through the screen of the mobile phone while making a voice call. The software developed on the mobile phone can realize three main monitoring functions, including realtime wav
16、eform and data monitoring, list trend data monitoring and the patient information checking. The doctor can select which he wants to check using the keyboard of the mobile phone. The whole system has been implemented in the laboratory environment. The main function of the system, i.e., transferring the waveform data
