Peritoneal dialysis connection system and method for using ultraviolet light emitting diodes

A peritoneal dialysis system comprising:

• a peritoneal dialysis fluid supply;
• a supply line in fluid communication with the peritoneal dialysis fluid supply, the supply line terminating at a supply connector;
• a patient connector in fluid communication with a patient's indwelling catheter;
• and
• a connecting device configured to be placed around both the supply connector and the patient connector to connect the supply connector to the patient connector without a user having to thereafter physically contact the supply connector or the patient connector;
• and
• a housing placeable around the connecting device, the housing including a plurality of ultraviolet (“UV”) light-emitting diodes (“LED's”) positioned to direct energy towards mating surfaces of at least one of the supply connector and the patient connector during a connection of the supply connector to the patient connector.
