title: Telemedicine system for patients on continuous ambulatory peritoneal dialysis.
abstract: Over recent decades, rapid progress in information and telecommunications technology has led to the application of these technologies in the medical field. In 1999, we reported on a telemedicine system (version 1.0) that used an automated peritoneal dialysis machine to collect data on patients with end-stage renal disease. After 2002, we focused on using cellular telephones in a new telemedicine system (version 2.0) to monitor patient data at home, including blood pressure (BP), heart rate, body weight, urine volume, and blood glucose. By 2003, we had developed a fully automatic system called I-converter (version 3.0) to collect data from a fully automatic device and send it via cellular telephone. After the fully automatic device measures a patient's BP, I-converter sends the data directly to the main server in our central data center. That server is directly connected to Web site by application service provider (ASP) technology. Recently, to make the system simpler, we developed a new version called D-converter (version 4.0). The telephone used in this new system is a Personal Handy-phone System (PHS). The PHS has several advantages: high-speed data transmission, low power output, little electromagnetic interference with medical devices, and easy locating of patients. The D-converter system uses a small computer and a PHS card called a Dopa card. Our telemedicine systems monitor continuous ambulatory peritoneal dialysis (CAPD) patients at home. For elderly and handicapped patients, these systems are very advantageous because they reduce visits to the outpatient clinic. In addition, data can be monitored at the patient's home in real time. The present paper reports our recent advances in telemedicine systems for CAPD patients.
