  • Patent number: 5330422
    Abstract: The device shown herein is made of essentially two parts one of which parts is essentially a hollow tube closed for a substantial distance at one end having a hollow cap with only a side opening therein. The second part is a rod with an end portion adapted to snugly fit into the interior of the cap of the first part. This second part is rotatable on its linear axis and when held in a particular axial position, the second part end portion is adapted to block the side opening so as to cut off communication between the interior and the exterior of this cap. This second part end portion has a cut-away section so that when this second part is rotated axially, preferably in the neighborhood of 180.degree. , this cut-away section is positioned adjacent to the side opening of the cap of the first part thereby allowing communication of fluid through the opening in said cap.

  • Patent number: 5250064
    Abstract: The surgical instrument guard described herein comprises a shield which fits over the blade of a scalpel and prevents accidental contact or "sticks" with the blade when not in surgical use. In one modification pressure of the surgeon's thumb or finger lifts the shield away from the blade so that the blade may be used in surgery. When the pressure is released, the shield returns to its protective position. In another modification the position of the blade is controlled by a peg or short bar extending into a slot in the side of a protective shield. The shield may be moved forward or backward as far as the slot can move with respect to the peg. When the shield is in the forward position, the shield covers the blade and protects against accidental "sticks". When the shield is moved backward, the blade is exposed and is available for surgical use.
