A non-sterile, portable, battery-powered device intended to provide the light source for a laryngoscope (i.e., rigid intubation type) when fitted into the laryngoscope handle. It typically consists of a removable cylindrical cell that produces light which is emitted from the laryngoscope handle via a fibreoptic laryngoscope blade for airway illumination. The device may be kinetically or electrically recharged. This is a reusable device.
