Closter: A New Connection for a Double-Bag System to Prevent Exogenous Peritonitis

Abstract

Although CAPD has been widely accepted as routine treatment for uremic patients, recurrent peritonitis still remains a limiting factor. Since 1978 to reduce the incidence of the peritonitis mainly due to exogenous origin, we have used a doublebag system with satisfactory results. To make easier the connection and to reduce the chances of contamination during the bag-exchange manoeuvre, we designed “Closter”, a new closed sterile connection. This device consists of a needle mounted on a Luer cap, and protected by a folding plastic cover. A thin diaphragm at the end of the needle closes the entire system. During the connecting manoeuvre, the cap is first locked to a branch of the Y adaptor connected to the Tenckhoff catheter, then the needle, driven with a slight pressure through the diaphragm and the antiseptic chamber, puts the system in line.
