  • Patent number: 5647502
    Abstract: A terrestrial wall mounted medical waste disposal container having a flexibly pivoted top closure lid is shown. The container includes a lid mount which is fitted in a sealing manner upon the top of the container, and a flexible lid which is attached to the lid mount. The lid mount has a recessed top face which abuts and slopes toward an entrance aperture in the top face of the mount. The flexible lid is divided into two portions by a living hinge. The larger and outer portion of the lid is pivotable along the hinge. In the lid's extreme opened position it lies flat on the recessed top face of the lid mount and so also slopes toward the entrance aperture; in this maximally extended position the lid's outer edge comes sufficiently close to the wall that it is impossible to deposit a waste item accidentally behind the lid or the container.

  • Patent number: 5533974
    Abstract: A safety catheter includes a pivoted cam and gripping wheel within a housing. As the catheter needle is withdrawn from the catheter the needle point is captured and locked within the housing, reducing the risk of needlestick injuries. When locked, the cam prevents the needle tip from being pushed out of the bottom of the housing, and the gripping wheel prevents the needle from being pulled out of the top of the housing. The sharp needle point is automatically covered and safely contained in the housing as it is withdrawn from the catheter.

  • Patent number: 5471705
    Abstract: A body, which may have a tubular or dome-like shape with an open top and bottom, has a wall with one or more elongated slots extending along the wall from the top toward the bottom. A cauterizer blade may be drawn through a slot in any suitable orientation to wipe debris from the blade. A mounting, such as a pressure-sensitive adhesive sheet, may be used to attach the body to a surgical drape. A slot may have two parallel inner edges for wiping or scraping the cauterizer blade. The distance between the inner edges defines the slot width, which should be approximately equal to the width of the cauterizer blade to be cleaned. The sides of the slot may be beveled to form chisel-like inner edges that enhance the wiping action. At the top of the body the slot may also have a "V"-shaped notch to guide the cauterizer blade into the slot. The adhesive sheet may be attached to the open bottom of the dome-shaped body.

  • Patent number: 5449068
    Abstract: Apparatus for safely and conveniently removing a blade from a surgical scalpel, and for disposing of used blades. The preferred embodiment includes an aperture through which the blade may be inserted into a container. The aperture is defined by parallel guide walls. A first and second shoulder project from one guide wall, and a third shoulder projects from the other guide wall. An angled blade deflector is disposed in the interior of the container, behind the aperture. Insertion of the scalpel blade into the aperture and against the angled blade deflector pushes the blade against the first and second shoulders, which causes the blade to deform and separate slightly from the handle and to engage the third shoulder. This third shoulder holds the rear of the blade within the aperture, so that manual withdrawal of the handle from the aperture detaches the blade from the handle, leaving the detached blade within the container for easy disposal.

  • Patent number: 5415180
    Abstract: An easily assembled system for handling surgical instruments includes as components (a) a waterproof container sized to fit into a ring of a conventional surgical ring-stand; (b) a waterproof expandable wrap sized to fit over such a ring prior to insertion of the container; and (c) a flexible, pliant, porous cradle, with handles, sized to fit into the container. The floor of the cradle is porous with respect to the sterile solution used to fill the container-cradle combination and into which bloodied surgical instruments are deposited. The cradle facilitates removal of the instruments by containing them when it is lifted out of the container, during which the now murky solution drains completely out of the cradle and into the container. The handles may be strengthened against tearing by three-dimensional curvilinear molding which pre-biases the handles and adjacent portions of the rim against the stress-pattern engendered by lifting significant masses of solids and undrained liquids.

  • Patent number: 5415315
    Abstract: A container lid for a medical storage-disposal container including a slide closure resistant to inadvertent movement from an open position into a fully closed and locked position. The container lid includes a top cover defining a disposal aperture and a laterally oriented depression. The slide closure contains a descending flange configured to engage the top cover depression and lock the slide closure in a fully closed position. An obstructing tab is pivotally coupled to the top cover and projects into the disposal aperture. The slide closure can only be moved into a fully closed and locked position if the obstructing tab is rotated into a non-obstructing orientation. The slide closure further includes protrusions on opposing lateral sides to require application of an affirmative force in order to displace the slide closure from a fully opened position.
