Abstract

An elliptical-shaped housing contains a UV light source and a power source. A connector is removably mounted in the housing and is disinfected or sterilized by UV light. A reflective coating inside the housing enhances the intensity of the UV light to disinfect or sterilize the connector.

Claims

1. An assembly for disinfecting a connection, comprising;

a connection comprising a first connector and a second connector;

a housing having an inner surface, an outer surface, a hinged cover to removably contain the connection, a first aperture within a first wall of the housing sized to receive the first connector, and a second aperture within a second wall of the housing sized to receive the second connector, the first aperture having a size different from the size of the second aperture;

an UV light source mounted inside the housing so that no portion of the UV light source contacts the housing inner surface; and

a power source and an electronic circuit for controlling electrical power to the UV light source;

wherein the first and second apertures are arranged within the housing to properly position the first connector and the second connector to receive UV light.

2. The assembly of claim 1, wherein the housing has a first chamber and a second chamber, the UV light source being mounted in the first chamber and the power source being mounted in the second chamber.

3. The assembly of claim 1, wherein the first connector includes a transfer set connector and the second connector includes a Y-set connector.

4. The assembly of claim 3, wherein the connectors are formed of a material that is transmissive of UV light.

5. The assembly of claim 4, wherein the transfer set connector and the Y-set connector are formed from a transmissive polymer.

6. The assembly of claim 1, wherein in the UV light source is ultraviolet C and has a wavelength in the range of 100 nm to 280 nm.

7. The assembly of claim 6, wherein the UV light includes any of a mercury lamp, light emitting diode, or fluorescent lamp.

8. The assembly of claim 1, wherein the housing comprises an elliptical shape and has a first foci F₁ and a second foci F₂, the UV light source being mounted at the first foci F₁, and the connection being mounted at the second foci F₂.

9. An assembly for disinfecting a connection, comprising;

a connection comprising a first connector and a second connector;

a housing having an inner surface, an outer surface, a cover, a first aperture within a first wall of the housing sized to receive the first connector, and a second aperture within a second wall of the housing sized to receive the second connector, the first aperture having a size different from the size of the second aperture;

an UV light source mounted in a first region; and

a power source and an electronic circuit for controlling electrical power to the UV light source mounted outside the first region,

wherein the first and second apertures are arranged within the housing to properly position the first connector and the second connector to receive UV light.

10. A method for disinfecting a connection, comprising;

providing the connection comprising a first connector and a second connector;

providing a housing having an inner surface, an outer surface, a cover to removably contain the connection, a UV light source, a first aperture within a first wall of the housing sized to receive the first connector, and a second aperture within a second wall of the housing sized to receive the second connector, the first aperture having a size different from the size of the second aperture; and

removably inserting the connection such that the first connector is positioned in the first aperture and the second connector is positioned in the second aperture, thereby properly positioning the connection for receiving UV light.
