Method for making a light handle cover
View Patent ↗A method of making a light handle cover including providing a first mold tool and a second mold tool. The first mold tool engages with the second mold tool to form a mold cavity. The mold cavity is injected with a moldable material. The light handle cover is formed as a single integral piece with a substantially cylindrical grab portion that is circumscribed on one end by a substantially circular base shield. A plurality of teeth are formed in the light handle cover. Each of the plurality of teeth is separated by a space. The light handle cover is ejected from the second mold tool with a burst of air.
1. In a light handle cover for use on surgical light handles, the improvement comprising:
a cylindrical grab portion having a distal end defining a handle receiving cavity;
a substantially circular base shield integrally connected with the cylindrical grab portion and having an annular recess spaced a predetermined distance from the cylindrical grab portion;
a plurality of teeth spaced a predetermined distance apart and including a base and a distal end, wherein a width of the base is larger than a width of the distal end and the distal end of the teeth define a circular handle receiving aperture, the plurality of teeth projecting inwardly toward the handle receiving cavity and also away from the distal end of the cylindrical grab portion prior to engagement with the surgical light handle and projecting inwardly toward the handle receiving cavity and also toward the distal end of the cylindrical grab portion during engagement with the surgical light handle; and
a circumferential channel defined between a connecting end of the teeth and the annular recess.
2. The light handle cover of claim 1 ,
wherein the distal end of the cylindrical grab portion is rounded and includes a thickened wall section.
3. The light handle cover of claim 1 , further comprising:
a shoulder ring between the base shield and the light handle cover.
4. The light handle cover of claim 1 , wherein the teeth include a generally trapezoidal shape.
5. The light handle cover of claim 1 , further comprising a thickened area where the teeth merge with the cylindrical grab portion.
6. The light handle cover of claim 1 , wherein the cylindrical grab portion, substantially circular base shield, and plurality of teeth are all integrally formed as a single unit in an injection molding process.
