  • Patent number: 4596329
    Abstract: A surgical instrument container has a top and bottom whose opposing surfaces are bordered by sidewalls and articulately connected to form an enclosed box. A planar substrate having upper and lower surfaces adapted to receive surgical instruments is pivotally mounted between the top and bottom. When the box is open, the substrate can be pivoted between the top and bottom to provide easy access to both upper and lower substrate surfaces. The substrate is positioned within the sidewalls of the top and bottom surfaces to effect enclosure of the substrate when the box is closed and thereby prevent retained surgical instruments from protruding through or falling out of the box. The substrate may be a porous foam or magnetic material or combination of each. The box may be mechanically or magnetically latched. The box may be composed of transparent material to permit visual inspection of the retained instruments when the box is closed.

  • Patent number: 4447238
    Abstract: A medical tube holder and its method of use are disclosed. The holder has a backing element having front and back faces, a portion of the back face having means to adhere to a substrate. The element has an elongate elastic strip having a free end and an end attached to the element suitable for wrapping around tubing to form a loop within which the tubing is held. Members possessing a mutual magnetic attraction are mounted on the front surface of the element for mutual engagement when the element is folded. After the tube is positioned within the loop, the free end of the strip is pulled to tighten the loop and is then positioned between the magnetic members. When the element is folded, the strip is held between the magnetic members to lock the tube within the loop.

  • Patent number: 4395807
    Abstract: A surgical blade remover is disclosed wherein a surgical blade is easily and effectively removed from the tang of a handle. The device is provided with two members which are spaced to form a channel sized to permit the tang to be positioned between them while the blade rests on the upper surfaces of the members. The channel between the members at their lower portions widens to permit the handle to enter the channel sufficiently that the heel of the blade can abut a projection which extends upward from each surface of the members. The handle enters this widened lower portion of the channel while the blade rests against the upper surfaces of the members thereby releasing the heel of the blade from the tang. The blade can then be removed from the handle by pulling the handle out of the channel because the projections prevent the blade from moving with the handle.

  • Patent number: 4344532
    Abstract: A surgical blade remover is disclosed having an essentially wedge-shaped support member which tapers from its front side to its back side. The support has one or more mutually parallel latitudinal slots open at one end and along their length extending from the front side of the support into its interior. The slots are sized to receive the tang of the blade holder while preventing the blade itself from passing therethrough. The surface of the support member bordering each slot is covered with an adhesive which holds the blade in place as the blade holder is pivoted downward in the slot away from the blade. When the hilt of the blade becomes detached from the holder, as a result of this pivoting action, the holder is withdrawn from the slot. The blade remains affixed to the adhesive on the support and is retained for its disposal.
