Abstract

Embodiments include a lighting assembly includes an elongate gasket body formed of a resilient, optically transmissive material. The gasket body includes a light source cavity at least partially defined by a light transmission portion and an attachment channel configured to attach the gasket body to a mount. A light source is disposed in the light source cavity. Other embodiments include securement ring including a clamp portion and a lighting assembly portion. The clamp portion includes first and second segments, each being semi-annular in shape and curving between first and second ends, the first end of the first segment coupled to the second end of the second segment and the second end of the first segment coupled to the first end of the second segment to collectively form an aperture. The lighting assembly portion includes a first and second segments, each being semi-annular in shape and including a light source.

First claim

What is claimed is:

1. A lighting assembly, comprising:
an elongate gasket body extending along a length and formed of a resilient, optically transmissive material, the gasket body comprising:
a light source cavity extending along the length, the light source cavity at least partially defined by a light transmission portion, the light source cavity being enclosed as viewed in a plane transverse to the length; and
an attachment channel extending along the length, the attachment channel configured to attach the gasket body to a mount; and

a light source disposed in the light source cavity and extending along the length, the light source arranged such that light emitted from the light source is incident and transmitted through the light transmission portion of the gasket body.

2. The lighting assembly of claim 1 , wherein the gasket body further comprises a sealing protrusion extending along the length, the sealing protrusion comprising a cavity extending along the length and being at least partially defined by a convex contact portion as viewed in a plane transverse to the length.

3. The lighting assembly of claim 1 , wherein the gasket body further comprises an attachment channel extending along the length, the additional attachment channel configured to attach the gasket body to an additional mount.

4. The lighting assembly of claim 1 , wherein the gasket body extends along the length between a first end and a second end, the light source cavity being open at at least one of the first end and the second end.

5. The lighting assembly of claim 1 , wherein the length of the gasket extends along a perimeter of a predetermined shape.

6. The lighting assembly of claim 1 , wherein the material diffuses light emitted from the light source and transmitted therethrough.

7. The lighting assembly of claim 1 , wherein the light source comprises one or more solid-state light emitters.

8. The lighting assembly of claim 1 , wherein the attachment channel comprises protrusions configured to engage the mount upon insertion into the attachment channel.

9. The lighting assembly of claim 1 , wherein:
the light transmission portion comprises an inner surface facing a light emitting surface of the light source; and
a distance from the light emitting surface of the light source to the inner surface along a direction orthogonal to the light emitting surface is 1 mm to 20 mm.

10. The lighting assembly of claim 1 , wherein a thickness of the light transmission portion along a direction orthogonal to the light emitting surface is 1 mm to 10 mm.

11. A medical device suspension system, comprising:
a mounting plate;
a spindle attached to the mounting plate;
a canopy comprising opposed major surfaces that are spaced apart from one another in a thickness direction, an end surface extending between the opposed major surfaces, and an orifice extending through the opposed major surfaces, the spindle extending through the orifice; and
the lighting assembly of claim 1 , wherein the end surface of the canopy is disposed in the attachment channel.

12. The medical device suspension system of claim 11 , wherein a securement ring retains the canopy in place with respect to the spindle, and wherein the securement ring comprises an additional light source.

13. A securement ring mountable to a cylindrical support member, the securement ring having a height along a longitudinal axis and comprising:
a clamp portion comprising a first segment and a second segment, each of the first and second segments of the clamp portion being semi-annular in shape and curving about the longitudinal axis between a first end and a second end, the first end of the first segment coupled to the second end of the second segment and the second end of the first segment coupled to the first end of the second segment such that the segments collectively form an aperture; and
a lighting assembly portion comprising a first segment and a second segment, each of the first and second segments of the lighting assembly portion being semi-annular in shape and curving about the longitudinal axis between a first end and a second end, an outer surface of each segment of the lighting assembly portion comprising a recess in which a light source is disposed.

14. The securement ring of claim 13 , wherein the light source comprises one or more solid-state light emitters arranged to radially emit light about the longitudinal axis.

15. The securement ring of claim 14 , further comprising a lens cover at the outer surface that covers the light source.

16. The securement ring of claim 15 , wherein the lens cover diffuses light emitted from the light source and transmitted therethrough.

17. The securement ring of claim 13 , wherein the segments of the lighting assembly portion are removably attached to respective segments of the clamp portion.

18. The securement ring of claim 13 , wherein a bottom surface of the first segment of the lighting assembly portion comprises pins and a top surface of the first segment of the clamp portion comprises holes that cooperate with the pins.

19. A medical device suspension system, comprising:
a mounting plate;
a spindle attached to the mounting plate;
a canopy comprising opposed major surfaces that are spaced apart from one another in a thickness direction, an end surface extending between the opposed major surfaces, and an orifice extending through the opposed major surfaces, the spindle extending through the orifice; and
the securement ring of any one of claim 13 retaining the canopy in place with respect to the spindle.

20. The medical device suspension system of claim 19 , further comprising a gasket at the end surface of the canopy, wherein the gasket comprises an additional light source.

21. A medical device suspension system, comprising:
a mounting plate;
a spindle attached to the mounting plate;
a cable management cover disposed around a portion of the spindle;
a canopy comprising opposed major surfaces that are spaced apart from one another in a thickness direction, an end surface extending between the opposed major surfaces, and an orifice extending through the opposed major surfaces, the spindle extending through the orifice; and
the securement ring of claim 13 retaining the canopy in place with respect to the cable management cover.

22. The medical device suspension system of claim 21 , further comprising a gasket at the end surface of the canopy, wherein the gasket comprises an additional light source.
