  • Patent number: 9980706
    Abstract: A cannula arrangement includes an inner tube disposed within an outer tube. A flexible sealing element is connected to a proximal portion of the outer tube. The flexible sealing element has a longitudinal axis coaxial with the outer tube. The flexible sealing element has a cantilevered portion that longitudinally extends a longitudinal distance parallel to the longitudinal axis in a proximal direction from the proximal end of the outer tube. The cantilevered portion has a projecting portion that projects diagonally toward the inner tube to define an interior edge to contact an outer surface of the inner tube.

  • Patent number: 9962233
    Abstract: Systems, devices, and methods are disclosed for the cleaning of an endotracheal tube while a patient is being supported by a ventilator connected to the endotracheal tube for the purpose of increasing the available space for airflow or to prevent the build up of materials that may constrict airflow or be a potential nidus for infection. In one embodiment, a method for cleaning endotracheal tubes comprises inserting a cleaning device within an endotracheal tube while a cleaning member is in a compressed position, radially expanding the cleaning member to an expanded position within the endotracheal tube, and withdrawing the cleaning device from the endotracheal tube with the cleaning member in the expanded position.

  • Patent number: 9956367
    Abstract: An airway device configured for intubation under blind or optionally under indirect vision of a fiber optic scope. It also configured to be used as a supraglottic airway device supporting external breathing or anesthesia circuits. The device comprises a tube system with expansion projections, a base, one or more inflation balloons, and a gastric suction tube. The device can include a stylet to guide endotracheal tube during intubation. The tube system can include an air tube and fiber-optic-probe tube. The balloon system can move the end of the tube system anteriorly to align it with the laryngeal opening. The balloon system can seal the airway leakage for low positive pressure ventilation for the device to operate as a supraglottic airway device. The inflation balloon and expansion projection can displace tissue that can block the airway path. The base can carry esophageal gastric drainage tube to the upper esophageal sphincter to block and drain gastric content regurgitation.

  • Patent number: 9925351
    Abstract: An aromatherapy device includes a housing forming two annular wells for retaining a scented fluid therein. Each well includes an insert positioned in the well to assist the retention of the fluid in the well by providing a second contact surface for the fluid to contact. The shape of the annular well and the viscosity of the fluid discourage the fluid from leaking out of the housing if laid on its side.

  • Patent number: 9907919
    Abstract: Especially during emergencies, there is a need for laryngeal mask heads with a ventral respiration chamber that has a cuff which surrounds the respiration chamber and which can be adjusted in size without having to be inflated. To meet said need, the laryngeal mask head comprises non-pneumatic structures to adjust the size of the mask head in the medial-lateral direction and the ventral-dorsal direction, which are preferably implemented by open, resilient channels extending in the same direction as the cuff.

  • Patent number: 9889265
    Abstract: An airway manifold includes a manifold body having an upper body portion and a lower body portion. The body portions are engaged such that the upper body portion is rotatable relative to the lower body portion, whereby a generally hollow interior space is defined. The lower body portion has a port open to the interior space, and the upper body portion includes a plurality of ports open to the interior space. A first upper body port is axially alignable with the lower body port to define a substantially linear passageway therebetween when the upper body portion is at a first rotatable position relative to the lower body portion. A second upper body port is axially alignable with the lower body port to define a substantially linear passageway therebetween when the upper body portion is at a second rotatable position.

  • Patent number: 9839345
    Abstract: In an endoscope, a flexible device of an elongated tube has a variable stiffness device. The variable stiffness device includes a movable control wire and a coil spring, to which compression force is applied to change stiffness. There occur changes in stiffness of the flexible device in plural radial directions of the coil spring at an equal point in an axial direction. The variable stiffness device is so constructed that a difference between maximum and minimum levels of stiffness of the variable stiffness device is set at most 0.2 time as much as stiffness of the flexible device with internal structures other than the variable stiffness device. Thus, unexpected grip feeling in manipulation of an operator at the time of advance can be removed in relation to undulating motion of the coil spring.
