  • Patent number: 11896762
    Abstract: An endotracheal tube airway patency system and method are provided. The system includes an endotracheal tube having a tube body having a proximal end, a distal end, an inner surface, a distal opening disposed at the distal end of the tube body, a proximal opening disposed at the proximal end of the tube body, and an airflow-effacing surface disposed within the tube body. The airflow-effacing surface includes a telescoping inner sleeve configured to be removed from the endotracheal tube body. The system further includes a tool for removal of the telescoping internal sleeve from the endotracheal tube body. The tool includes an elongated body having a proximal end and a distal end; a handle located at the proximal end of the elongated body; and at least one extension member disposed at the distal end of the elongated body. The at least one extension member is configured to couple to the telescoping internal sleeve for removal of the telescoping internal sleeve from the endotracheal tube body.

  • Patent number: 11883553
    Abstract: Seal integrity indicators for sterilization containers are provided. For example, a seal indicator may indicate whether the container is sufficiently sealed to prevent an ingress of contaminants into the container. If the container is sufficiently sealed, the seal indicator is visible, but if not, the seal indicator is not visible. Thus, the seal indicator undergoes a change in state when the sterilization container transitions from unsealed to sealed, or vice versa, such that a user may ascertain whether the container is properly sealed to maintain the container's sterility. An exemplary seal indicator includes an invertible projection formed with the container gasket that is not visible from outside the container until inverted, due to force applied by the lid, to extend through an opening in the container body. Closure mechanisms for sterilization containers also are provided.

  • Patent number: 11752294
    Abstract: A respiratory access assembly may include a manifold having a first mating surface defining a first port opening. The respiratory access assembly may include a rotatable adapter having a second mating surface defining a second port opening and a seal assembly disposed between the manifold and the rotatable adapter that includes a first seal ring, a second seal ring, and an outer seal ring disposed proximate an outer perimeter of at least one of the manifold or the rotatable adapter. The rotatable adapter may be rotatable relative to the manifold between an open configuration and a closed configuration. The seal assembly may include a connection portion connected between the first seal ring and the second seal ring. The connection portion may form a seal between the first mating surface and the second mating surface between the first seal ring and the second seal ring.

  • Patent number: 11478321
    Abstract: Indicators for indicating the integrity of a seal of a sterilization container are provided. For example, a seal indicator may indicate whether the container is sufficiently sealed to prevent an ingress of contaminants into the container. If the container is sufficiently sealed, the seal indicator is in one state and displays a first indicium, and if the sterilization container is not sufficiently sealed, the seal indicator is in another state and displays a second indicium. Thus, the seal indicator undergoes a visible change in state when the sterilization container transitions from unsealed to sealed, such that the user may be assured that the container is properly sealed to maintain sterility of the articles post-sterilization. Further, the seal indicator undergoes a visible change in state if the seal is subsequently broken, to signal to the user that the seal and the sterility of the container interior has been compromised.

  • Patent number: 11273233
    Abstract: Closure mechanisms and seal integrity indicators for sterilization containers are provided. For example, a closure mechanism comprising at least one handle and at least two arms is provided with a sterilization container lid to apply a more uniform or evenly distributed force to a container gasket. A container body defines an inner lip on which the gasket and lid are received such that the sealing interface is recessed within the container. Further, a seal indicator may indicate whether the container is sufficiently sealed to prevent an ingress of contaminants into the container. If the container is sufficiently sealed, the seal indicator is visible, but if not, the seal indicator is not visible. Thus, the seal indicator undergoes a change in state when the sterilization container transitions from unsealed to sealed, or vice versa, such that a user may ascertain whether the container is properly sealed to maintain the container's sterility.

  • Patent number: 10987185
    Abstract: The present disclosure provides sterilization containers with features for sealing a volume against an ingress of contaminants. The present disclosure also provides a sterility breach detection system for detecting whether the sterilization container seal has been breached, which potentially could compromise the sterility of any contents of the container. Further, the present disclosure provides a controller system for detecting, tracking, and alerting a user to the state of a sterilization container, such as whether the container seal has been breached. The sterility breach detection system and/or the controller system may utilize a smart gasket to detect breaches in a seal of a sterilization container, and a controller in operative communication with the smart gasket may activate an indicator to alert a user to a detected breach in the seal.

  • Patent number: 10683138
    Abstract: Handles for containers and sterilization containers are provided. For example, a handle for a sterilization container comprises a base portion, a grip portion connected to the base portion, and a stop. The base portion is repositionable with respect to the container to change an orientation of the grip portion with respect to a bottom surface of the container. In some embodiments, a sterilization container comprises a body having a bottom surface, a lid, a first handle attached to a first end of the body, and a second handle attached to a second end of the body. Each handle includes a base portion rotatable within a plane parallel to the respective end of the body to reposition the handle with respect to the body, which changes an orientation of a grip portion of each handle with respect to the bottom surface.
