Abstract

An ambulatory dialysis system and connector which effectively prevents peritoneal infections such as peritonitis. The connector is comprised of a cylinder containing a disinfecting solution which continuously bathes the male and female connectors of a tube during use. A highly absorbent material is packed in the cylinder and saturated with a disinfectant and bathes the male and female connectors when connection is made and continually bathes them during use. A connection is provided by a male fitting on the end of a tube connected to a container of dialysate fluid or an abdominal opposing tube. A male connector is inserted into the female connector through the cylinder containing the absorbent material saturated with the disinfectant. The absorbent material is packed such that the male connector contacts the absorbent material during insertion to disinfect the opposing ends simultaneously while connection is being made. Once the dialysate fluid is delivered to the patient through the connector, the tube may be pulled off the outer end of the male connector to remove the empty containers. The male connector is then sealed and capped.

Claims

1. A method of protecting a tube connection from contamination during peritoneal dialysis comprising;

forming cylindrical means;

packing said cylindrical means with an absorbent material substantially filling said cylindrical means;

saturating said absorbent packing material with a disinfectant;

surrounding a connection site of first and second telescopically mating tube ends with said cylindrical means packed with said saturated absorbent material;

said saturated absorbent material being kept in continuous intimate contact with said connection of said first and second telescopically mating tube ends throughout use;

whereby said connection of said telescopically mating tube ends is continuously protected from contamination throughout use.

2. The method according to claim 1 in which said cylindrical means is formed as a pair of telescopically mating cylinders on each end of said first and second telescopically mating tube ends whereby one of said telescopically mating tube ends is pushed through said saturated absorbent packing material to mate with the other of said mating tube ends.

3. The method according to claim 2 including forming locking means on said telescopically mating cylindrical means;

whereby said telescopically mating cylindrical means are locked together around said telescopically mating tube ends after the connection is made.
