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: 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.

Abstract: Disclosed is a video laryngoscope having a body, an insertion section extending from the body generally parallel to a median plane of the laryngoscope extending through the body, and a display screen assembly extending from the body generally perpendicular to the median plane, the body comprising a grip portion intermediate the display screen assembly and the insertion section. The display screen assembly, comprising a display screen, extends laterally from the body and the inner edge of the display screen falls within the lateral extent of the body. The grip portion is also of a minimum size to allow an adult to grip the laryngoscope, the hand abutting the screen assembly.

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 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: The invention relates to medical devices for carrying out internal examination, such as laryngoscopes. The laryngoscope is provided with a camera element within a channel inside the blade.

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 laryngoscope insertion section for a laryngoscope, which is typically a video laryngoscope, includes a lateral tube guide configured to retain an endotracheal tube in a plane. A viewing port for a camera or other image collector is laterally displaced from the plane of the endotracheal tube. The said plane of the endotracheal tube is aligned substantially in the same plane as a patient's median plane and the tube can be advanced into the larynx using a natural curving motion similar to the motion used to introduce an endotracheal tube using a convention laryngoscope. In a preferred embodiment, the distal tip of the insertion section and a retained endotracheal tube will be located in the patient's median plane during intubation. As the tube guide retains endotracheal tubes substantially in a plane, lateral curvature is avoided, reducing resistance to advancement of the tube.

Abstract: A video laryngoscope and elongate laryngoscope insertion section for a video laryngoscope, comprising a viewing port through which an imaging device within the insertion section can obtain images of a larynx, the insertion section extending between a distal end for insertion into a subject and an opposite proximal end, and having an inferior surface and an opposed superior surface, wherein the insertion section comprises a proximal region where the insertion section extends through a subject's teeth in use, a distal region extending to the distal end and an intermediate region therebetween, wherein the inferior surface of the insertion section comprises or consists of a curved region which extends from the proximal region through the intermediate region to the distal region, wherein the curved region of the inferior surface is continuously longitudinally curved along the length of the longitudinally curved region and wherein the longitudinal curvature of the curved region of the inferior surface varies in the
