Abstract: A breathing apparatus (10) comprises a breathing circuit which includes a gas reservoir (50) having one end (54) open to the atmosphere. The reservoir comprises a substantially rigid structure and may be supplemented by an inflatable bag. The circuit is connected, in use, to an oxygen supply container (60), the apparatus further including means (62) for regulating the flow of oxygen into the circuit in response to detect gas levels in the circuit. The preferred apparatus is portable and provides an efficient use of oxygen.

Abstract: One aspect of the present invention provides a laryngoscope comprising a blade; a doployable mirror, and an operating mechanism, the operating mechanism being arranged to deploy the mirror. The mirror is pivotable with respect to the blade and the arrangement is such that an initial operation of the operating mechanism causes the mirror to be deployed while further operation of the operating mechanism causes the mirror to be pivoted with respect to the blade. In the preferred embodiment, the blade has a pivotable tip which is also operable by the operating mechanism. The deployment of the mirror, the pivoting of the mirror 30 and the pivoting of the tip 18 can all be performed by operation of a single operating mechanism, preferably in the form of a simple lever. The laryngoscope may therefore readily be operated using only one hand and without the need for any dextrous finger movements.
