  • Patent number: 11937864
    Abstract: The invention relates to a magnetic-navigation joint type puncture needle which comprises a head section and needle sections, wherein, the head section is made of stainless steel material with high magnetic conductivity and is connected with the following needle sections coaxially mounted with the head section through a flexible joint; two needle sections are also coaxially connected with each other through a flexible joint; the needle sections are made of non-magnetic stainless steel material; the flexible joints adopts serpentine tubes formed by melting and engraving cobalt-chromium alloy through laser; and both the head section and the needle sections can be bent, but the flexibility of the head section and that of the needle sections are smaller than the flexibility of the flexible joints.

  • Publication number: 20230276950
    Abstract: Multilayered cushions and positioners include a plurality of compressible layers, at least of which may include a breathable chamber that holds compressible beads. The compressible beads may flow until an object is placed thereon or until the compressible layer is placed against a surface. A compressive force exerted by the object or the surface on the beads may compress them, causing the beads to conform to a shape of the object or surface and increasing a coefficient of friction of the beads, which may hold the beads in position and increase a rigidity of the cushion or positioner at the location thereof that receives the object or surface. An intermediate element, such as a pressurizable element, may be positioned between compressible layers to prevent forces exerted one of the compressible layers from being communicated directly to the other compressible layer.

  • Publication number: 20230106871
    Abstract: An infection control filter label includes a frame and a filter membrane that covers a window through the frame. The frame may be removably secured to a cover for an item, such as a cushion (e.g., a pillow, a positioner, a mattress topper, a mattress, a seat cushion, etc.), bedding (e.g., a duvet, etc.), or the like to provide a sealed cover for the item. The sealed cover may be impermeable, with the infection control filter label limiting the passage of dust and microorganisms (e.g., fungi, bacteria, mold spores, etc.) from passing therethrough. Thus, the sealed cover may protect its contents from external factors (e.g., sick individuals, etc.) while protecting the environment outside the sealed cover from the contents of the sealed cover. Information about the item may be provided on the frame; for example, by printing, writing, or the like.

  • Patent number: 11123509
    Abstract: Disclosed is a respiratory treatment apparatus that may be especially helpful for pediatric patients, though it may be useful for patients of all ages. In one embodiment, the apparatus comprises an endotracheal tube that is physically coupled to a bronchial blocker in a non-concentric fashion. In another embodiment, the apparatus comprises an endotracheal tube that is physically coupled to a steering balloon apparatus. The endotracheal tube, bronchial blocker, and/or steering balloon apparatus may be non-unitary components that are attachable to one another with one or more attachment structures, and once physically coupled, may be put to use. The endotracheal tube and bronchial blocker and steering balloon apparatus may be selected from a plurality of endotracheal tubes and bronchial blockers and steering balloon apparatus, to create an assembled apparatus that meets the needs of the patient.

  • Patent number: 10596051
    Abstract: The present invention relates to a system and method for sacral and trochanteric support and off-loading. The system provides a ultra low pressure plenum and a positioner. The patient body size and size and corresponding surface area of the positioner control the amount of gas which is displaced evenly against the walls of the ultra low pressure plenum to allow the combination of the ultra low pressure plenum and the positioner to slightly lift a patient from a bed surface, thereby offloading the sacrum and trochanter. The positioner can be an ultra low pressure bladder.

  • Patent number: 10363185
    Abstract: The present invention relates to a system and method for support and off-loading. The system includes an inner bladder filled with a flowable composition. An outer bladder filled with a flowable composition is positioned adjacent to the inner bladder. The composition of the inner bladder has greater flow characteristics than the composition of the outer bladder. The inner bladder micro-contours to the received body part and the outer bladder macro-contours to the inner bladder after the inner bladder is micro-contoured to the received body part. Alternatively, the system provides a pair of ultra low pressure plenums and a positioner. The patient body size and size and corresponding surface area of the positioner control the amount of gas which is displaced evenly against the walls of the ultra low pressure plenums.

  • Patent number: 10016326
    Abstract: The present invention relates to a support for a body part including a compression device in combination with a lower leg protection system. The compression device can be integral with the outer support at a position received over the lower leg. One or more valves can extend from a compression bladder for attachment to a pneumatic device. Inflation of the compression bladder positioner adjacent the lower leg also displaces air in the outer support toward the foot which causes simultaneous massaging of the foot. The pneumatic device can be adjusted to provide either sequential or intermittent therapies. The outer support can include a rigid outer shell for providing support.

  • Patent number: 9120666
    Abstract: The present invention provides a method and system for customization of flow characteristics of a support using permanent and controlled evacuation of interstitial gas during the manufacturing process. The flow characteristics can be customized to provide a stiffer or less stiff support by a comparative degree. The flow characteristics can be permanently changed. The support includes a bladder filled with a fluidized particulate material. The medium of the fluidized particulate material includes interstitial spaces. A predetermined amount of gas can be removed to provide a support having a desired specific support characteristic.
