Abstract: 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.

Abstract: 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.

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.

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.

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.
