Abstract

Hand held and portable disinfection units for use with patients having indwelling catheters hospitalized or under care in an intensive care unit.

Claims (21)

1. A UV disinfection device for disinfecting catheter connectors, comprising

a body having a first end and a second end, the body shaped to be held in a hand of a user;

a generally barrel shaped opening positioned at or near the first end of the body, the opening having a first opening end and a second opening end and shaped to receive a catheter connector, the generally barrel shaped opening being open at the first opening end and closed at the second opening end such that a catheter connector to be disinfected is insertable only through the open first opening end;

a generally cylindrical shaped kill zone within the opening;

a UV-C transmissive lumen positioned within the kill zone;

a plurality of UV-C LEDs positioned around a circumference of the kill zone at two or more circumferential planes along a length of the kill zone; and

a sensor for identifying a particular catheter connector inserted in the generally barrel shaped opening and operable to enable disinfection of the particular catheter connector only when the particular catheter connector is recognized as an authorized catheter connector.

2. The disinfection device of claim 1 , comprising a disinfection progress indicator.

3. The disinfection device of claim 1 , comprising a sensor to sense insertion of a component within the barrel-shaped opening.

4. The disinfection device of claim 2 , wherein insertion of a component is configured to trigger at least one of activation, authentication, and logging disinfection information using a controller of the device.

5. The disinfection device of claim 3 , wherein the sensor is configured to interact with a tag on the component configured to be inserted within the barrel shaped opening.

6. The disinfection device of claim 1 , wherein the device comprises a head portion positioned at an angle relative to a body portion.

7. The disinfection device of claim 1 , comprising a UV-C LED positioned in the proximity of the first or second opening ends of the barrel shaped opening.

8. The disinfection device of claim 1 , further comprising a display.

9. The disinfection device of claim 1 , comprising about 4-12 UV-C LEDs positioned within the barrel shaped opening.

10. The disinfection device of claim 1 , wherein the UV-C LEDs are symmetrical about a longitudinal axis of the opening.

11. The disinfection device of claim 1 , comprising a rechargeable battery.

12. The disinfection device of claim 1 , wherein the device is configured to transmit data to a separate device or database through a wired or wireless connection.

13. The disinfection device of claim 7 , wherein the UV-C LED positioned in the proximity of the first or second end of the barrel shaped opening is positioned in the proximity of the second end of the barrel shaped opening.

14. The disinfection device of claim 1 , wherein the disinfection device is operable to log complete disinfection cycles for the particular catheter connector.

15. The disinfection device of claim 1 , wherein the disinfection device is operable to log incomplete disinfection cycles for the particular catheter connector.
