A metal laryngoscope blade with a resiliently elastically deformable metal blade hook-on fitting for removable double snap engagement into an operative intubation position on a laryngoscope handle with a correspondingly sized handle hook-on fitting.

A laryngoscope assembly with enhanced viewing capability including a laryngoscope handle having a permanently mounted laryngoscope optical system. The laryngoscope optical system has a view tube with a leading aperture lens for affording a field of view along a deflected line of sight viewing in an operative intubation position. The laryngoscope handle includes a laryngoscope optical system securing arrangement for mechanically securing the laryngoscope optical system in the operative intubation position. The laryngoscope assembly also includes an interchangeable laryngoscope blade including a trailing view tube sleeve for slidably mounting on the view tube and a leading spatula wherein the view tube sleeve has a leading transparent window for covering the aperture lens. The laryngoscope assembly further includes a blade securing arrangement for mechanically securing the laryngoscope blade on the laryngoscope handle in the operative intubation position.

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. A laryngoscope (60) comprising a handle comprising a demountable battery pack (10) comprising one or more batteries (20) and an arm (49) operable to retain a demountable laryngoscope blade.

A blade for a laryngoscope having a handle, the blade having an elongated body having a central axis, and having a distal tip symmetric about the central axis; a downwardly convex arcuate central portion including a first flange and a second flange is disclosed herein. Each flange has a distal flange tip and a proximal base, the first flange tip being a mirror image of the second flange about the central axis. The outer edge of the base of the first flange is convex and the outer edge of the base of the second flange is concave with respect to the central axis. A light attachment area is provided along the central axis. The distal tip may have any one of a variety of shapes, including having outer rounded lobes, being generally rectangular, or having a spoon shape.

A tongue stabilizer includes a tongue-engaging plate that is held on a laryngoscope blade by pressure sensitive adhesive, with a foam strip in-between to compensate for any irregularities between the tongue-engaging plate and the laryngoscope blade. The tongue-engaging plate is cup shape to cradle the tongue to prevent the tongue from interfering with the visibility and process of intubation. A protective strip can be used to cover the adhesive.
