许多方面已经展示了使用移动电话和互联网的远程医疗应用。无线通信和计算机网络技术的融合是当前电信行业的一个趋势，无线应用协议（WAP）设备的出现就是一个例子。由于WAP也将成为未来移动通信设备的共同特征，因此研究其在远程医疗中的应用是值得的。本文介绍了我们实验室开发的基于wap的远程医疗病人监护系统的实现和经验。它利用WAP设备作为移动接入终端，实现一般问诊和病人监护服务。授权用户可以在WAP设备上以存储转发模式浏览患者的一般数据、监测血压（BP）和心电图（ECG）。用无线标记语言（WML）、WMLScript和Perl编写的应用程序驻留在内容服务器中。建立MySQL关系数据库系统，用于存储血压读数、心电数据、患者病历、诊所和医院信息以及医生与患者的预约。建立了一个无线心电子系统，用于在室内环境下记录动态心电并将心电数据存储到数据库中。在测试过程中，电路交换数据（CSD）使用一部符合WAP 1.1标准的WAP电话，在GSM 1800兆mhz的频率上，通过香港流动电话服务供应商提供的WAP网关与内容服务器连接。从数据库中成功检索数据并显示在WAP手机上。该系统显示了WAP在远程患者监护和患者数据检索中的可行性。
Many parties have already demonstrated telemedicine applications that use cellular phones and the Internet. A current trend in telecommunication is the convergence of wireless communication and computer network technologies, and the emergence of wireless application protocol (WAP) de. vices is an example. Since WAP will also, be a common feature found in future mobile communication devices, it is worthwhile to investigate its use in telemedicine. This paper describes the implementation and experiences with a WAP-based telemedicine system for patient-monitoring that has been developed in our laboratory. It utilizes WAP devices as mobile access terminals for general inquiry and patient-monitoring services. Authorized users can browse the patients' general data, monitored blood pressure (BP), and electrocardiogram (ECG) on WAP devices in store-and-forward mode. The applications, written in wireless markup language (WML), WMLScript, and Perl, resided in a content server. A MySQL relational database system was set up to store the BP readings, ECG data, patient records, clinic and hospital information, and doctors' appointments with patients. A wireless ECG subsystem was built for recording ambulatory ECG in an indoor environment and for storing ECG data into the database. For testing, a WAP phone compliant with WAP 1.1 Was used at GSM 1800 MHz by circuit-switched data (CSD) to connect to the content server through a WAP gateway, which was provided by a mobile phone service provider in Hong Kong. Data were successfully retrieved from the database and displayed on the WAP phone. The system shows how WAP can be feasible in remote patient-monitoring and patient data retrieval.
