Abstract

Peritoneal dialysis systems and methods are provided by the present disclosure. In a general embodiment, a peritoneal dialysis system includes a peritoneal dialysis fluid supply, a supply line in fluid communication with the peritoneal dialysis fluid supply and terminating at a supply connector, a patient connector in fluid communication with a patient'"'"'s indwelling catheter, a device configured to connect the supply connector to the patient connector without a user having to physically contact the supply connector or the patient connector, and a housing placeable around the connecting device and including a plurality of ultraviolet (“UV”) light-emitting diodes (“LED'"'"'s”) positioned to direct energy towards at least one of the supply connector and the patient connector.

Claims

1. 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;

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 sized so as to be placed about the connecting device and including a plurality of ultraviolet (“

UV”

) light-emitting diodes (“

LED'"'"'s”

) positioned to direct energy towards at least one of the supply connector and the patient connector.

2. The peritoneal dialysis system of claim 1, wherein the plurality of UV-LED'"'"'s are configured to deliver about 200 milliJoules of energy in a period of about a minute.

3. The peritoneal dialysis system of claim 1, wherein at least one of the supply connector and the patient connector is at least partially opaque to UV light.

4. The peritoneal dialysis system of claim 1, which includes a transfer set, the transfer set connecting the patient connector to the indwelling catheter.

5. The peritoneal dialysis system of claim 1, wherein the housing is hinged or halved to fit around the connecting device.

6. The peritoneal dialysis system of claim 1, which is configured to emit UV light from the UV-LED'"'"'s just prior to the supply connector and the patient connector being mated via the device.

7. The peritoneal dialysis system of claim 1, which is configured to emit UV light from the UV-LED'"'"'s just after the supply connector and the patient connector are disconnected via the device.

8. The peritoneal dialysis system of claim 1, wherein the peritoneal dialysis fluid supply includes a supply bag.

9. 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.

10. The peritoneal dialysis system of claim 9, wherein the device includes a UV transmissive material that allows the UV-LED'"'"'s to direct energy inwardly through the device.

11. The peritoneal dialysis system of claim 10, wherein the device allows the UV-LED'"'"'s to direct energy inwardly through the device at a plurality of locations.

12. The peritoneal dialysis system of claim 9, wherein an inner surface of the housing includes a UV light reflective material.

13. The peritoneal dialysis system of claim 9, which is configured to power a first portion of the plurality of UV-LED'"'"'s for a period of time and a second portion of the plurality of UV-LED'"'"'s after the period of time.

14. The peritoneal dialysis system of claim 9, wherein the peritoneal dialysis fluid supply includes a supply bag.

15. The peritoneal dialysis system of claim 9, wherein the UV-LED'"'"'s are positioned to direct energy towards mating surfaces of at least one of the supply connector and the patient connector just prior to and during the connection of the supply connector to the patient connector.

16. The peritoneal dialysis system of claim 9, wherein the UV-LED'"'"'s are positioned to direct energy towards mating surfaces of at least one of the supply connector and the patient connector during and just after disconnecting the supply connector from the patient connector.
