referring to the figures , there is generally disclosed in fig1 - 4 a disposable cover for the handle of a light head ( e . g ., surgical light head ). surgical light heads , such as the one illustrated by way of example in fig1 , are commonly used in sterile environments ( e . g ., operating rooms ) for directing light onto a desired area and capturing video at the same time . surgical light heads can vary in size , shape and light output . generally , a surgical light head 12 such as illustrated in fig1 includes a positioning handle 14 that extends generally perpendicularly outward from the light emitting surface . video capturing ( e . g ., camera ) equipment is generally housed within the handle 14 . the camera in the handle 14 is configured to capture images / video from surgical procedures and / or for clinical teleconferencing . using the handle 14 a physician or technician is able to control the position and direction of the camera in the handle 14 and the light emitted from the light head . as best illustrated in fig2 - 3 , the cover 10 comprises a generally elongated hollow body or member 16 . the body 16 is generally cylindrical or tubular in shape . the body 16 includes a first end 18 that is open . when the cover 10 is mounted on the handle 14 , the handle 14 is received into the body 16 through the open first end 18 of the cover 10 . the body also includes a second end 20 opposite the first end 18 of the cover 10 . in one aspect of the invention , the contour of the body 16 tapers generally from a larger to smaller profile from the first end 18 to the second end 20 . in another aspect of the invention , the first end 18 of the body 16 includes a collar 30 having a generally larger diameter profile to accommodate a collar on the handle 14 of the light head 12 . the body 16 of the cover 10 from the collar 30 to the second end 20 is generally tubular ( i . e ., a fixed diameter along this defined length ). the second end 20 terminates in a rim 24 . a lens 22 is recessed within the body 16 of the cover 10 behind the rim 24 . the lens 22 extends across the body 16 of the cover 10 to close off the second end 20 at an optimal depth ( e . g ., ½ - ¾ of an inch ) behind the rim 24 . the lens 22 is recessed within the second end 20 behind the rim 24 to protect the lens from incidental or unwanted contact . the thickness of the sidewalls of the body 16 and lens 22 are generally thin ( e . g ., 80 - 120 thousandths of an inch ). in one aspect of the invention , the collar 30 is configured to secure the cover 10 to the handle 14 of the light head 12 . for example , the collar 30 includes a tab 28 ( as best illustrated in fig4 ) having a detent 32 that creates an interference fit against the outside surface of the handle 14 or a counter reciprocal feature on the outside surface of the handle 14 . the interference between these features removably secures the cover 10 to the handle 14 to prevent the cover 10 from unintentionally separating from the handle 14 , particularly during manipulation of the light head 12 . according to one aspect of the invention , the tab 28 is perforated along edges contiguous with the collar 30 to allow the tab 28 and detent 32 to be separated from the collar 30 to prevent reuse of the cover 10 . the cover 10 is preferably manufactured or produced as a single - piece . in one aspect , the lens 22 is single unitary piece integral with the body 16 of the cover 10 . the cover 10 is preferably injection molded as a single , unitary piece . in a preferred form , the cover 10 is injection molded from a clear thermoplastic resin , such as for example , a polycarbonate material . other thermoplastic materials , that are preferably clear , are also contemplated such as urethane , polystyrene , polyethylene , polymethyl methacrylate , etc . the mold is configured with cosmetic texturing ( e . g ., by in - mold texturing ) to create a frosted appearance of the surface 26 , such as a textured , generally translucent appearance . the lens 22 is left untextured ( e . g ., polished steel tooling is used for surfaces of the mold forming the lens 22 ) and possesses the optically - clear , transparent properties of the clear thermoplastic material used to form the cover 10 . in this embodiment , the lens 22 is configured of the same material used to produce the body 16 of the cover 10 and is molded - in with the body 16 of the cover 10 , for example , during the injection molding process . the single - piece construction of the cover 10 prevents the unnecessary and unwanted handling , shipping and stocking of multiple parts for constructing a single handle cover . the rim 24 extending outward from the lens 22 also helps to protect the lens 22 from being damaged , scratched , scuffed or dirtied during handling , packaging , shipping , attachment and / or use . the cosmetically frosted surface 26 of the body 16 camouflages smudges and other contrasting marks received during handling , packing , shipping , attachment and / or use . text and other advertising / branding artwork and text can also be included on the surface 26 and be clearly visible due to the contrasting frosted surface 26 of the cover 10 . the above specification , examples , and information provide a description of the manufacture and use of the compositions of the invention . since many embodiments of the invention can be made without departing from the spirit and scope of the invention , the invention resides in the claims hereinafter appended .
the invention is a disposable cover handle cover for a surgical light head , and more particularly to a single - piece , integrally - formed disposable handle cover for a surgical light head and the like . the disposable cover includes a single - piece hollow member having a first open end adapted to receive the positioning handle of the surgical light head housing a camera and a second open end generally opposite the first end . the second end is closed off by a lens disposed within and integral with the hollow body .
