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.
Claims13
A video laryngoscope comprising a body, one or more batteries which are integral to the body, and a memory storing a value indicative of the remaining available rated capacity of the one or more batteries, the video laryngoscope further comprising a usage recording device operable to determine when the video laryngoscope is operated and to update the value stored in the memory responsive to such usage to reflect the consumption of power from the one or more batteries resulting from the operated video laryngoscope.
