  • Publication number: 20210031021
    Abstract: Aspects of the present invention relate to a medical tube for delivering nutrients or medication to a patient. The tube comprises a flexible tubular body for conveying the nutrients or medication to the patient and a small-bore connector for connecting the medical tube to a syringe or pump. The small-bore connector is secured to the tubular body by an overmoulded component that encapsulates a portion of the tubular body and a portion of the connector thereby securing the connector relative to the tubular body of the medical tube.

  • Patent number: 9993362
    Abstract: An adjustable knee brace for fitting a variety of leg sizes and adjustable to limit flexion or extension motion of a knee. The knee brace includes an adjustable length provided by a strut that telescopes within a receiver. A latch assembly mounted on the receiver selectively applies a frictional force to lock the strut member and the receiver against relative telescoping movement. An adjustable range of motion hinge is operatively associated with the telescoping strut. The hinge includes a hinge plate connected to the strut member and having a semi-circular peripheral edge defining a plurality of uniformly spaced apart keys. A range of motion stop is movably positionable relative to the semi-circular peripheral edge and includes a movable latch having teeth.

  • Publication number: 20160317774
    Abstract: Various embodiments of a connector assembly are provided to removably couple a proximal end of a tracheal tube to components associated with a ventilator or an anesthesiology machine. The disclosed embodiments include a compression fitting, which creates an airtight seal between walls of the tracheal tube and components of the compression fitting, thus allowing air to flow to and from a patient.

  • Publication number: 20140290649
    Abstract: Various embodiments of a tracheal tube having a suction lumen are provided. For example, the suction lumen may be associated with two spaced apart pressure transducers, whereby a pressure drop between the transducers indicates that the suction lumen is free of blockages and a characteristic lack of pressure drop and/or particular pressure curve is indicative of a blockage. In addition, embodiments may include a tracheal tube with sensors configured to sense a buildup of secretions. The sensors may be located proximate to an opening in the suction lumen. In other embodiments, a blockage-clearing system for a suction lumen may be provided that blows air into the suction lumen to clear blockages. In particular, in certain embodiments, the blockage-clearing system may operate to create its own pressurized air source by utilizing the pressure change created in the suction line by a blockage.

  • Patent number: 8408210
    Abstract: According to various embodiments, a tracheal tube ventilating device includes a sealing portion near a distal end of the tube. The sealing portion has an electroactive polymer configured to undergo a clinically effective change in volume, thickness, or both upon application of an electrical potential. Such a change in volume, thickness, or both enables sealing of the device against an inner surface of a trachea while permitting the free passage of ventilating gas through the tube. In addition, at least one electrical conductor is coupled to the electroactive polymer and is configured to apply the electrical potential.

  • Publication number: 20110290254
    Abstract: A tracheal tube assembly includes a connector body, a cannula extending from the connector body, and an insert that provides rigidity to the connector body and retains the cannula in the connector body. The cannula has a tapered upper end that fits between conforming tapered sections of the connector body inner surface and the insert. The insert may include features to prevent rotation of the cannula as well as rotation of the insert in the connector body. Features of the insert and connector body may also interface to mechanically retain the insert in the connector body. Different sizes of cannula may be accommodated by different inserts, while using the same or different connector bodies.

  • Publication number: 20110265798
    Abstract: Various embodiments of a tracheal tube having spaced lumens and an associated ported adapter are provided. The lumens of the tracheal tube are spaced around the circumference of the tracheal tube to facilitate evacuation (e.g., suctioning and blowing) and other applications at various locations around the circumference of the tracheal tube. The ported adapter includes lumen extensions that may be inserted into the lumens of the tracheal tube, thereby forming a connection between the ported adapter and the tracheal tube. More specifically, hollow ports extending through the lumen extensions and the body of the ported adapter facilitate connection of the lumens of the tracheal tube with external equipment such as, for example, evacuation equipment for suctioning and blowing into and out of the lumens of the tracheal tube.
