of this study was to design and implement an integrated Telemedicine system, able to handle different Telemedicine needs especially in the fields of: 机械专业中英文文献翻译 10 • Emergency health care provision in ambulances, Rural Hospital Centers (or any other remote located health center) and navigating Ships • Intensive care patients monitoring • Home telecare, especially for patients suffering from chronic and /or permanent diseases (like heart disease). In other words we determined a Multipurpose system consisting of two major parts: a) Telemedicine unit (which can be portable or not portable depending on the case) and b) Base unit or doctor39。 s unit (which can be portable or not portable depending on the case and usually located at a Central Hospital). Figure 1 describes the overall system architecture. In each different application the Telemedicine unit is located at the patient39。 s site, whereas the base unit (or doctor39。 s unit) is located at the place where the signals and images of the patient are sent and monitored. The Telemedicine device is responsible to collect data (biosignals and images) from the patient and automatically transmit them to the base unit. The base unit is prised of a set of userfriendly software modules, which can receive data from the Telemedicine device, transmit information back to it and store important data in a local database. The system has several different applications (with small changes each time), according to the current healthcare provision nature and needs. Before the system39。 s technical implementation, an overview of the current trends and needs in the aforementioned Telemedicine applications was made, so that the different requirements are taken into account during design and development, thus ensuring maximum applicability and usability of the final system in distinct environments and situations. Table 1 provides the results of this overview, which was done towards a predefined list of criteria that usually influence a Telemedicine application implementation (cost, portability, autonomy, weight and size of Telemedicine device, type and quality of 机械专业中英文文献翻译 11 PC and camera, munication means used). Besides the above, the Telemedicine applications can be examined towards other criteria, like for example security needs, transmission type (continuos, store amp。 forward) needs, ECG leads required (3 or 12 leads), etc. These last are examined in more detail in the next paragraph, where the overall technical description of the system is provided. System design and technical implementation As mentioned above, the system consists of two separate modules (Figure 1): a) the unit located at the patient39。 s site called Telemedicine unit and b) the unit located at doctor39。 s site called Base Unit. The Doctor might be using the system either in an Emergency case or when monitoring a patient from a remote place. The design and implementation of the system was based on a detailed user requirements analysis, as well as the corresponding system functional specifications. The study was mainly based on the experience of Telemedicine projects named AMBULANCE [22] and Emergency 112 [33] where functional prototypes of a device with emergency Telemedicine functionalities was built and extensively evaluated. Through these project we had phased the need to implement a telemedicine device, which would facilitate a flexible architecture and could be used in several emergency or monitoring cases that have simiral needs of information transmition. The Telemedicine unit is responsible for collecting and transmitting biosignals and still images of the patients from the incident place to the Doctor39。 s location while the 机械专业中英文文献翻译 12 Doctor39。 s unit is responsible for receiving and displaying ining data. The information flow (using a layered description) between the two sites can be seen in Figure 2. a) Telemedicine Unit The Telemedicine unit mainly consists of four modules, the biosignal acquisition module, which is responsible for biosignals acquisition, a digital camera responsible for image capturing, a processing unit, which is basically a Personal Computer, and a munication module (GSM, Satellite or POTS modem). The biosignal acquisition module was designed to operate with some of the most mon portable biosignal monitors used in emergency cases or in Intensive care Units such as a) CRITIKON DINAMAP PLUS Monitor Model 8700/9700 family of monitors, b) PROTOCOLWelch Allyn Propaq 1xx Vital Signs Monitor, c) PROTOCOLWelch Allyn Propaq Encore 2xx Vital Signs Monitor. The biosignals collected by the patient (and then transmitted to the Base Unit) are: • ECG up to 12 lead, depending on the monitor used in each case. • Oxygen Saturation (SpO2). • Heart Rate (HR). • NonInvasive Blood Pressure (NIBP). • Invasive blood Pressure (IP). • Temperature (Temp) • Respiration (Resp) 机械专业中英文文献翻译 13 The PC used depends on the type of the Telemedicine application (role of the Telemedicine unit). As shown in Table 1: a) in cases where the autonomy and small size of the system are important (mainly in ambulances), a sub notebook like Toshiba libretto 100 ct portable PC is used, a picture of a portable device is shown in Figure 3 b) in cases where we need some autonomy but size is not considered an important element a Typical Pentium portable PC is used。 c) in cases where we do not necessarily need autonomy, portability and small system size, a Typical Pentium Desktop PC is used. The control of the Telemedicine unit is fully automatic. The only thing the telemedicine unit user has to do is connect the biosignal monitor to the patient and turn on the PC. The PC then performs the connection to the base unit automatically. Although the base unit basically contr。
