Nasal and oral/nasal mask, for non-invasive artificial respiration, is molded from a synthetic material by heat and pressure, using numerical photographic data to shape the mold according to the patient's features

摘要

The nasal and oral/nasal mask (1) is shaped from photography of the raised and recessed zone of the patient's facial features by numerical photography. The numerical photographic data are used to generate a program to shape the interior of a mold, step-by-step, in the required mask structure. The mold shapes a sheet of synthetic material by heat and pressure, together with inserts of blocks of resin or metal alloy.. A cushion (16) is formed to lie against the skin
