Abstract
Abstract An assembly for attachment to a conventional operating room light fixture includes a handle and a disposable cover. The handle has an upper portion adapted to be attached to the light fixture. The handle further includes an annular rigid disk at a central portion thereof and an annular ring provided below the annular rigid handle flange and defining a groove therebetween. A grip portion is provided at a lower portion of the handle. The assembly also includes a sterile, disposable cover, including a hollow grip cover having a closed end and a flexible flange formed integrally with the grip cover at an open end thereof and adapted to be fitted over the grip portion of the handle and advanced thereon. The disposable cover further includes a circular rigid cover flange attached to the flexible flange and curved away from the rigid disk when the grip cover is fitted over the grip portion of the handle, with the rigid disk restraining further advancement of the rigid cover flange. The rigid cover flange also includes an opening corresponding to the open end of the grip cover, and a plurality of snaps provided along the circumference of the opening and adapted to be fitted within the groove to securely fit the disposable cover over the handle. For industry-standard handles available with some operating room light fixtures, a light handle adapter may be attached to the standard handle to secure the disposable cover onto the handle. The light handle adapter is slid up the handle toward the light fixture. The light handle adapter may be affixed to the light handle by an adhesive or other mechanical means, and the disposable cover is secured to the light handle adapter.
