Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
97 words
A device for moistening and warming inhalation air with tracheotomy and endotracheal intubation, said device having a cavernous body which is made of a light, porous material having an open pore structure and which is encased in a cylinder-like casing of light material having open ends and having a porosity which is denser than that of the body, said cavernous body completely filling said Cylinder, a recess extending through the casing into the body intended to function as a passage-way through said casing for air passing between said cavernous body and a patient through a tracheal tube.
