Abstract

A sterilizable multi-part handle for attachment to a handle receiving fitting of a hospital surgery room light fixture is made of light weight, inexpensive molded plastic parts which are disposable after use, the handle including a handle body having a body grip portion and a threaded head portion to engage the fixture fitting and a disc separate from the handle which is provided with a central aperture via which the disc is assembled to the handle in a snap on fit connection between the handle body and disc. The exemplary connecting means includes a plurality of detents provided on the inner periphery of the disc aperture which snap into and seat within a disc receiving groove provided in the handle body head portion adjacent a disc seating flange against which the disc seats when the handle is turned into tight engagement with the associated light fixture fitting. A sterilized kit of handle parts is disclosed wherein a pair of nested handle bodies seat in side by side relation upon a pair of stacked disc with a retainer strap thereabout to hold the array in such preassembled compact relation within a sterilized peel back type package.

Claims

1. A sterilizable multi-part handle for attachment to a handle receiving fitting on a medical surgery room light fixture, said handle comprising:

a handle body having a body grip portion and a head portion to engage said fitting;

a disc separate from said handle and having a central aperture within a surrounding annular web; and

connecting means associated with said handle body head portion and said disc aperture for mounting said disc to said handle body preparatory to mounting said handle to said light fixture.

2. The sterilizable multi-part handle of claim 1 wherein:

said handle body is provided in the form of a molded one-piece sterilizable plastics material tubular body having a body grip portion having a scored exterior surface and said head portion is a hollow boss having an exterior pipe type thread.

3. The sterilizable multi-part handle of claim 2 wherein:

said disc is provided in the form of a molded one piece sterilizable plastics material disc.

4. The sterilizable multi-part handle of claim 3 wherein:

said body grip portion and disc are provided with an enveloping thin walled disposable plastic material cover.

5. The sterilizable multi-part handle of claim 4 wherein:

said disc has a peripheral bead and said cover has an annular flange, said head fitting snugly within said flange.

6. The sterilizable multi-part handle of claim 1 wherein said connecting means comprises:

a seating flange on said handle body head portion generally adjacent said body grip portion against which said disc seats when assembled thereto.

7. The sterilizable multi-part handle of claim 1 wherein said connecting means comprises:

a disc receiving groove in said head portion adjacent said seating flange which receives said disc partially therein when said disc is seated against said seating flange.

8. The sterilizable multi-part handle of claim 7 wherein said handle body head portion has an integral snap ring like annular protuberance portion adjacent said disc receiving groove over which said disc must pass to enter said disc receiving groove.

9. The sterilizable multi-part handle of claim 7 wherein said handle body head portion is provided with a relief groove between said annular protuberance portion and said disc receiving groove providing resiliency to said protuberance portion to facilitate said disc passing over the same into said disc receiving groove.

10. The sterilizable multi-part handle of claims 7, 8 or 9 wherein said disc is provided with a plurality of detents protruding inwardly of said central aperture to snap over said adjacent portions of said head portion as said disc is seated against said seating flange.

11. The sterilizable multi-part handle of claim 1 wherein said connecting means comprises:

a annular protuberance about said handle body head portion having an outer diameter smaller than the inner diameter of said disc central aperture; and

one or more detents protruding inwardly of said central aperture on said disc to provide an interference snap on fit of said disc to said handle body when said disc aperture is forced over said annular protuberance.

12. The sterilizable multi-part handle of claim 11 wherein said one or more detents have chamfered end surfaces facing laterally of said disc to facilitate said snap on fit of said disc to said handle body.

13. A sterilized package kit of easily assembled multi-part light weight plastic molded handles for use with a medical surgery room light fixture having a handle receiving fitting, said kit being provided within a sterile package and comprising:

a pair of discs in stacked relation, one on top of the other;

a pair of handle bodies in side by side relation and resting on said one of said discs; and

a retainer strap wound about and holding said handle bodies and discs in a compact array thereof prior to their removal from said package and assembly of said discs to said handle bodies to provide assembled handles.

14. The kit of claim 13 wherein:

said pair of handle bodies each have a grip portion of generally uniform outer dimensions and a head portion of larger outer dimensions than said grip portions; and

said handle bodies are nested in side by side relation with the head portions of each of said bodies lying adjacent the grip portion of the other.

15. The kit of claim 13 wherein:

said retainer strap comprises an easily frangible paper like material.

16. The kit of claim 13 wherein said pair of discs are provided in the form of two individually molded, one piece circular and centrally apertured sterilizable plastic material discs.
