Publication number: 20190216309Abstract: A laryngoscope insertion section comprising a tube guide including at least an inferior tube guiding member and a superior tube guiding member, wherein the thickness of the insertion section in a first region is less than the external diameter of the largest diameter endotracheal tube in an operating range of endotracheal tube sizes plus the thickness of the inferior tube guiding member plus the thickness of the superior tube guiding member. Typically, the insertion section comprises an elongate member and the tube guide is lateral of the elongate member. Typically, an endotracheal tube is retained within the tube guide in flexural tension.Type: ApplicationFiled: January 15, 2019Publication date: July 18, 2019Inventors: Matthew John Ross McGrath, Morgan James Walker

Publication number: 20190195955Abstract: 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.Type: ApplicationFiled: February 28, 2019Publication date: June 27, 2019Inventors: Matthew John Ross McGrath, Peter Douglas Colin Inglis, Brian Alan Laffoley

Publication number: 20190142262Abstract: A multifunctional visualization instrument is provided that, in certain embodiments, includes a body having a proximal end and a distal end. The multifunctional visualization instrument includes a display screen on the body and a camera stick at the distal end of the body and comprising an arm and a camera. The arm of the camera stick is sized to fit within a channel of a removable laryngoscope blade. The multifunctional visualization instrument includes a port on a surface of the laryngoscope, configured to mate with an introducer and a steering input for steering the introducer, displayed on the display screen simultaneously with an image of the patient captured by the camera.Type: ApplicationFiled: November 13, 2018Publication date: May 16, 2019Inventors: Peter Douglas Colin Inglis, Hua Yang, Matthew John Ross McGrath, Michael Ng, Andrew J. Gano, Rhea Marie May

Publication number: 20190142263Abstract: A video laryngoscope has an arm comprising a video camera, at least one electrical conductor extending to the video camera, an elongate electrical conductor retaining member retaining the electrical conductor and an overmoulding extending around the elongate cable retaining member and having a smooth outer surface. Providing a laryngoscope arm overmoulded to provide a smooth outer surface has the benefit of allowing the laryngoscope arm to be readily cleaned or sterilised, and minimises the number of features, such as seams or joints, where dirt or infectious bodies may be retained.Type: ApplicationFiled: November 30, 2018Publication date: May 16, 2019Inventors: Matthew John Ross McGrath, Peter Douglas Colin Inglis

Publication number: 20190133430Abstract: A laryngoscope system includes a body having a handle and an arm, a camera mounted on a distal end of the arm, and a removable blade having a channel sized to fit over the arm to couple the blade to the body. The blade includes a magnet, and a sensor disposed in the body is responsive to the magnet. The laryngoscope system also includes a processor disposed in the body and programmed to enable at least one monitoring function in response to a signal from the sensor.Type: ApplicationFiled: October 29, 2018Publication date: May 9, 2019Inventors: Peter Douglas Colin Inglis, Matthew John Ross McGrath, Michael Ng

Publication number: 20180084984Abstract: 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.Type: ApplicationFiled: September 14, 2017Publication date: March 29, 2018Inventors: Matthew John Ross McGrath, Peter Douglas Colin Inglis
