A sterile disposable plastic cover for a handle of an operating room fixture such as a cylindrical handle for a light fixture is disclosed. The cover includes a hollow member which is open at one end and includes a hand guard. The open end is partially restricted with a retention member which permits the handle of the operating fixture to extend through the open end of the hollow member and holds it in place. Preferably, the retention member is a disc which includes a pair of intersecting slits which define an opening smaller than the opened end of the hollow member.

Why it's free to use
- Filed June 7, 1990 and granted April 21, 1998. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 7, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 7, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
