Medical respiratory apparatus
First Claim
1. A medical respiratory apparatus including a cylindrical respiratory chamber which is at least in part at least translucent, the chamber containing, in use, a fluid intended for inhalation that is water or an aqueous solution of a medicament intended for inhalation, such chamber including a float member formed of an inert material, the float member being a ring adapted to float upon the water or aqueous solution intended for inhalation such that sufficient of the surface of the water or aqueous solution is exposed to permit entrainment of the water or aqueous solution intended for inhalation in the atmosphere above it, the float member having a shape conforming to the internal shape of the chamber and an overall diameter slightly less than the internal diameter of the chamber, at least the outer peripheral surface of the float member having a coloration distinct from that of the water or aqueous solution to be contained within the chamber, whereby the level of the water or aqueous solution within the chamber can be readily observed.

Abstract
A medical respiratory apparatus includes a chamber (10) which is at least in part at least translucent. The chamber (10) includes a float member (12) formed of an inert material and contains, in use, a fluid intended for inhalation. The float member (12) is adapted to float upon the fluid intended to be contained within the chamber (10) and has a peripheral dimension adjacent, but less than, the internal peripheral dimension of the chamber (10). At least the outer peripheral surface of the float member (12) has a coloration distinct from that of the fluid to be contained within the chamber such that the level of the fluid within the chamber (10) can be readily observed.

-
a cylindrical respiratory chamber which is at least in part at least translucent, the chamber containing, in use, a fluid intended for inhalation that is water or an aqueous solution of a medicament intended for inhalation, and a float member positioned within the chamber, the float member being formed of an inert material of lower density than the water or aqueous solution intended for inhalation, such that the float member is adapted to float upon the water or aqueous solution intended for inhalation, the float member being a ring that conforms to the internal shape of the chamber and has an overall diameter slightly less than the internal diameter of the chamber such that sufficient of the surface of the water or aqueous solution is exposed to permit entrainment of the water or aqueous solution intended for inhalation in the atmosphere above it, and at least the outer peripheral surface of the float member having a coloration distinct from that of the water or aqueous solution to be contained within the chamber during use, whereby the level of the water or aqueous solution within the chamber can be readily observed.
