Design and testing of the Baxter Integrated Disconnect Systems (IDS)

This paper describes the result of a miltidisciplinary approach to the design and evaluation of a new CAPD disconnect system: the Baxter Integrated Disconnect System (IDS). This system consists of a bag full of fresh Dianeal, an empty bag for the drainage of spent dialysate and tubings connecting the 2 in a Y fashion. With this system, the patient makes only one connection. The system is disposable. The major property that makes this unique is that all components are preassembled, and the whole system is steam-sterilized as 1 unit. In general, similar systems use different sterilization methods for the various components of the system. Those components are then assembled, under clean conditions by the manufacturer, without final sterilization of the unit. Assembly of the components is sometimes left to the patient. The concept of IDS, therefore, is unique and warrants lower rates of contamination. This system has been tested on patients for a total observation period of 765 patient months, and has proven to be simple, safe and effective. It yields a 63% probability of peritonitis-free patients at 24 months.
