  • Patent number: 10261135
    Abstract: An electrical device includes a memory storing a value indicative the remaining available rated capacity of one or more batteries. The stored value is changed in use to reflect reducing capacity. The initial stored value is chosen so that there is a very high (e.g. >99.9%) confidence that the one or more batteries will provide at least the capacity indicated by the initial stored value. This reduces the chance of failure during emergency procedures. The one or more batteries may be integral to the electrical device. An override facility is provided.

  • Patent number: 9833587
    Abstract: A camera tube used in connection with a laryngeal mask cooperates with an intubation stylet. The camera tube is an elongate member having a length extending between opposite distal and proximal ends of the elongate member. The distal end of the camera tube has a camera. The camera tube has an exterior surface and an intubation stylet guide support surface extending radially outward from the exterior surface along a portion of the length adjacent to the distal end. The intubation stylet guide support surface is configured to cooperate with an intubation stylet guide support surface. The user may manipulate the proximal end of the camera tube to change the orientation of the intubation stylet with in the laryngeal mask while using the camera to visualize the patient's laryngeal opening. Once the intubation stylet is aligned with the patient's laryngeal opening, the intubation stylet may be advanced therethrough.

    Abstract: Video-based laryngoscopes having an external centrally located channel coursing from the handle to a curved blade configured to deliver an ETT to a trachea as visualized by a non-removable, or alternatively, a removable video camera and lighting unit located beneath the external channel. The channel laryngoscope may be made for single use in a patient and discarded, or be processed for re-use. Alternatively, the channel laryngoscope may have a removable video camera and lighting member located within an internal chamber that runs parallel with the external channel. In another embodiment a laryngoscope adapter may be detachably affixable to the channel laryngoscope equipped with the non-removable camera to provide a decontaminated or sterile surface to permit re-use of the channel laryngoscope without having to undergo washing or decontamination procedures.

    Abstract: Apparatuses for guiding an endotracheal tube during intubation and associated methods of their use; the apparatuses formed to contain a plastic element able to hold deformations so as to conform the apparatus to the shape of a patient's endotracheal airway. The plastic element has sufficient give so as to minimize traumatic engagement with the inner surface of the airway lumen. Methods for using the apparatuses exploit indirect visualization where the person performing the intubation can shape the apparatuses so as to place the distal end into the field of view of the indirect visualization instrument even with minimal alignment of the patient's airway.

  • Publication number: 20130197312
    Abstract: A laryngoscope has a first and second handle portion defining an internal cavity and forming a handle assembly. The laryngoscope includes a first and second blade portion defining an internal cavity and forming a blade assembly. A light and camera source within the internal cavity of the blade assembly illuminates at least a portion of the blade assembly and obtains images of the operation of the laryngoscope. A microprocessor coupled to the camera is mounted within one internal cavity and can record images from the camera. The microprocessor provides on-board recording capable of capturing video and audio and event data, such as from a simulator. A keypad is configured to provide for on-Board event flagging of the recorded data recorded by the microprocessor. The microprocessor may wirelessly transmit data from the laryngoscope.

  • Patent number: 8479739
    Abstract: A system and method for endotracheal intubation of airways are disclosed. A malleable stylet having a distal end and a proximal end, a charged coupled device (CCD) at the distal end and a transmitter, at or near the proximal end or connected to the proximal end of the stylet with connectors, transmits video to a visualization device comprising a receiver means, a display means, and a display support adapted to be worn on an operator in a position so that the operator can view the display with one eye while simultaneously viewing the airway directly. The display support is typically worn on the head of a physician. A second display can be worn by a student or observer. In some instances, the transmitter means and receiver means are wireless.

  • Patent number: 8460184
    Abstract: The claimed subject matter provides systems and/or methods that facilitate improving visualization associated with intubation. A dynamically articulating laryngoscope blade can be controlled to configure to normal anatomic variants and pathologic abnormalities to facilitate placing of an endotracheal tube into a patient's trachea. Further, cameras can be integrated into and/or mounted upon the dynamically articulating laryngoscope blade. The cameras can enable stereoscopic visualization of the laryngeal aperture allowing for depth perception. Moreover, the cameras can be moved independently of the blade allowing for optimal viewing of the laryngeal opening.

  • Patent number: 8419634
    Abstract: The claimed subject matter provides systems and/or methods that facilitate improving visualization associated with intubation. A dynamical articulating laryngoscope can include a handle assembly and a blade assembly. The blade assembly can further include a main blade assembly, a proximal blade assembly, and a distal blade assembly. A medium control articulation point can couple the main blade assembly and the proximal blade assembly, and a fine control articulation point can couple the distal blade assembly and the proximal blade assembly. Further, the proximal blade assembly can pivot relative to the main blade assembly around the medium control articulation point and/or the distal blade assembly can pivot relative to the proximal blade assembly around the fine control articulation point. Pivoting about the medium control articulation point and/or the fine control articulation point can be effectuated by one or more blade control components.

  • Publication number: 20130072757
    Abstract: A battery pack (10) for an electrical device (60) has a cover portion which forms part of the assembled electrical device (60) and a seal (78) for forming a waterproof seal between the battery pack (10) and the electrical device (10). Thus, every new battery pack can form a fresh seal with the electrical device (60), allowing effective waterproofing. A battery pack (10) for an electrical device (60) includes a memory storing a value indicative the remaining available rated capacity of the battery pack (10). The stored value is changed in use to reflect reducing capacity. The initial stored value is chosen so that there is a very high (e.g. >99.9%) confidence that the battery pack will provide at least the capacity indicated by the initial stored value. This reduces the chance of failure during emergency procedures. An override facility is provided.

  • Publication number: 20130060089
    Abstract: Disclosed is a laryngoscope insertion section having a curved superior surface and a curved inferior surface, and a channel extending from the proximal end the channel having an inferior internal surface with a greater curvature than the curvature of the inferior surface. The insertion section is compatible with laryngoscope hardware optimised for indirect viewing, yet enables direct viewing. Additionally, the distance between the inferior and superior surfaces is at a maximum within the intermediate portion, and enables the dimensions of the proximal and distal portions to be minimized. Thus, the intermediate portion, which is located in the patient's oral cavity in use, is provided with greatest depth and therefore strength where the greatest forces are received, whereas the distal and proximal portions are of reduced dimensions to as to minimize trauma to the patient's airway and mouth areas, respectively, in use.
