  • Patent number: 4637513
    Abstract: A disposable surgical implement collector wherein a lamination of sponge plastic is provided at intervals with a series of spaced ribs, the ribs and adjacent portions of the lamination being depressed at intervals to form clearly marked channels dividing the ribs into a series of embossments which are numbered; each embossment adapted to receive a surgical needle or other small disposable surgical instrument; the sponge plastic lamination being bonded to a relatively rigid lamination provided with fold lines so that the complementary sections of the needle collector thus formed may enclosed the surgical instruments for disposal; the collector being provided with means for maintaining the collector in a folded condition.In one embodiment, each rib is folded upon itself in opposite lateral direction to confront adjacent portions of the laminations.

  • 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: 4385692
    Abstract: A surgical instrument tip protector has a cushioned foam base member for receiving a surgical instrument positioned thereon and a cover member which overlies a lower portion of said base and is peripherally bonded to said base to form an open-ended pocket to protect the instrument tip. The cover is a single integrally formed material comprising a foam portion which is essentially opaque and a non-porous portion which is essentially transparent located to permit the visual inspection of said instrument tip. The cover is formed by providing a single piece of foam and applying heat and pressure to a predetermined area to form the non-porous transparent portion.

  • 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.

  • Patent number: 4336806
    Abstract: A medical tube holder and its method of use are disclosed. The holder has a backing strip having front and back faces, a portion of the back face being adapted to adhere to a substrate, such as a surgical drape. The backing strip has preferential tube receiving locations and is movable between a folded and unfolded position. Members possessing a mutual magnetic attraction are mounted on the front surface of the strip for mutual engagement when the strip is folded. The tubing is secured within the preferential receiving locations between folded sections of the strip when the strip is in its folded position.
