The objective is to produce a system that confine the respiratory flow environment of an infected patient, from his initial pickup until the end of his treatment (ambulance or helicopter transport, hospital stay). For this, the patients’ ENT sphere ( ear, nose and throat) is isolated thanks to a bubble slightly depressurized and attached to the patient. The system allows cares provide to the patient while being comfortable to wear.

Validation of the idea has been made with an experiment representing a severe risk of contamination: an open nebulizer has thus been used as particles generator. The Cirrus 2 (Intersurgical©, France) nebulizer was issued by a 9 L/min oxygen flow. Particles count, at 1m far from the patient, has been done thanks to an industrial laser counter usually used in white rooms with a particle size sensitivity from 0.3 to 25 µm (Lasair III, Particle Measuring Systems©, CO, USA). Particles diffusion and filtration has been clearly observed.
