  • Patent number: 11759276
    Abstract: A drape (600) suitable for covering non-planar surfaces of equipment (1201) is provided. The drape (600) facilitates quick and efficient deployment while ensuring that a sterile field established by a drape portion (601) is not compromised. The drape (600) can include a drape wrapping layer (209) wrapped about a drape portion (601) that is formed initially with two abutting elongated accordion fold stacks (604,605). Non-sterile personnel (801) can handle the drape wrapping layer (209) to position the drape (600) along surfaces of the equipment (1201) without touching the sterile drape portion (601). Sterile personnel can then expand the abutting elongated accordion fold stacks (604,605) to drape the surfaces of the equipment (1201).

  • Patent number: 10912621
    Abstract: A stockinette (200), suitable for covering an appendage (1440) of a patient, includes one or more folds (206). The fold (206) can be in a length of material (205) disposed between an open end (204) and a closed end (203). Alternatively, the fold (880) can be in an optional cuff (860) formed by a section of material (661) near the open end (603). Folds can be present both in the length of material (205) and in the cuff (860) as well. The cuff (860) can be disposed atop the fold (206) in the length of material (205). The stockinette (200) enables one person to apply the stockinette (200) to an appendage (1440) with one continuous motion that expands the folds.

  • Patent number: 10413469
    Abstract: A patient positioner (100) includes a central portion (102) and a pair of shoulder restraints (105,106) extending distally away from a first side (107) of the central portion. Each shoulder restraint can terminate at an attachment area (108,109). Each attachment area can comprise fastener (114,115). Complementary fasteners (214,215) can be disposed on the central portion (102). The shoulder restraints can then be folded (116) about a patient's shoulders, with the fasteners attaching to the complementary fasteners. A plurality of securement straps (121,122,123,124,125,126) configured to attach the patient positioner to a procedure table (701) can extend distally from the second side (110) and the third side (111) of the central portion, respectively.

  • Patent number: 9050085
    Abstract: Medical lens assemblies and sterile drapes with a lens assembly are presented herein. In one embodiment, a lens assembly includes an annular lens housing that is attachable to a medical drape. The lens housing is configured to releasably attach to a medical device, such as a surgical microscope. An annular lens cover holder is removably attachable to the lens housing. A lens cover for shielding the objective lens is pivotably hinged to the lens cover holder. In another embodiment, a drape assembly includes a flexible body sized to cover an optical device. A lens housing attached to the drape body is engageable with the optical device to attach proximate an objective lens thereof. A lens cover holder is removably attached to the lens housing to rotate about a first axis. A lens cover is mounted to the lens cover holder to pivot about a second, different axis.

  • Patent number: 8464722
    Abstract: An equipment drape (1000) is made from an elongated drape body (1401) that includes an equipment opening (1041). The elongated drape body (1401) is telescopically folded (1403) to form a telescopic drape body (1404). An accordion fold (1501) is then applied to form a rectangular shape (1503). The distal edges (1011,1012) are then folded back over the rectangular shape (1503) to meet at a longitudinal part (1511). Insertion indicators (1043,1044) can be attached to the equipment opening (1041). A user can easily and quickly insert their hands into the equipment opening (1041) to deploy the equipment drape (1000) with a single motion without having to first fumble with and unfold the drape.

    Abstract: An adjustable drape (100) is manufactured from a flexible fabric layer and has a front major face (201) and a rear major face (101). One or more wearer attachment devices (102,103) are disposed along the rear major face (101), while one or more adjustment devices (202,203) are disposed along the front major face (201). When the flexible fabric layer attached to the chest of a wearer (400), it is not visible from the behind the wearer (400). Accordingly, the adjustable drape (100) can be used to preserve patient dignity during advanced imaging procedures.
