A dispensing apparatus for serially dispensing plastic bags from a wound roll of continuous flexible plastic bags joined along perforated severance lines. A container is provided which is adapted to receive the wound roll of plastic bags. The container has a bottom, a pair of opposed sides having an inwardly facing flange extending therefrom, and a separating tongue projecting outward from the bottom. The flanges define a self-threading slide for threading the plastic bags from the wound roll along a predetermined path onto the separating tongue. The separating tongue separates the plastic bags from the wound roll as the plastic bags engage the separation tongue along a predetermined path of travel. A mounting bracket cooperates with the bottom to mount the container to a solid surface in a plurality of different positions while maintaining the desired orientation of the container, to ensure that the wound roll is biased against the bottom and the flanges for self-braking of the wound roll and for limiting overspinning thereof as plastic bags are serially separated therefrom.

Methods and devices are provided for maintaining visibility during surgical procedures. In general, the methods and devices can allow for a surgical instrument to maintain visibility during a surgical procedure using a protective element coupled to the surgical instrument. The protective element can protect a viewing element on the surgical instrument while the surgical instrument is being passed through an introducer device into or out of a body cavity (e.g., during insertion and/or withdrawal). The protective element can also optionally protect the surgical instrument's viewing element while at least a portion of the surgical instrument is disposed in a body cavity.

There is provided an inflatable cushion inflated through a single inflation valve. A pair of inflated panels held in place by at least one tie strap connecting the panels rest beneath each end of the bottom of an article to be protected. The cushion has a pair of inflatable end chambers interconnected to the bottom panels and a pair of inflatable side chambers interconnected to the end chambers, which when inflated protect the ends and sides of the article. This is facilitated by internal openings which allow the inflated panels to easily bend underneath the ends of the article and around the corners. There are recesses at each corner which extend from each corner of one internal opening toward a peripheral edge of the cushion to provide a wedge-like portion of the side chambers. In one of the embodiments, an additional pair of internal openings facilitates a pair of top inflatable chambers interconnected to the end chambers to rest on the top of the article. In another embodiment of the present invention, the top chambers are interconnected by inserting an inflatable hook located a the periphery of one of the top chambers through a hook receiving member located on the other top chamber to interlock the chambers together. The receiving member may be an inflatable extension of one of the top chambers and the receiving member has an opening therein for retaining the hook.

In another embodiment of the present invention, the chamber protecting the upper portion of the article includes a single inflatable chamber which folds across the top of the article. The top chamber has an internal opening in the middle thereof formed by a weld. Extending inwardly from the weld are portions of each thermoplastic sheet which remain after the cushion has been cut and adapted to hold a thin article.
