AUTONOMOUS DEVICE FOR PROTECTING A PERSON, A MATERIAL OR A PRODUCT AGAINST THE RISK OF CONTAMINATION, BY AN AIR HARNESS WITH ULTRA CLEAN HORIZONTAL FLOW FLOW.
An autonomous device for protecting a person, a material or a product against the risk of contamination The invention relates to an autonomous device for producing an ultra-clean horizontal laminar flow air beam with controlled temperature and hygrometry, in the field of a zone sensitive to contamination, by means of a horizontal "C" -shaped air circuit, open on the laminar flow air beam and suspended on any structure. Under the beam, a plan connected to the circuit makes it possible to have a support for a medical or surgical act, for the research, for the production of continuous industrial products or for products of high technologies. Masts fixed inside the "C" horizontal lying between the upper and lower segments and on either side of the beam, allow the attachment of ancillary equipment. A motorized system partially hooked on the high structure, allows to raise or lower the device and to vary the height of the worktop and beam. The device according to the invention is particularly intended for protection against the risk of contamination in the hospital sector, food industry, pharmaceutical laboratories, micro and nano technologies, aerospace and high technologies. Dispositif autonome permettant de protéger une personne, une matière ou un produit contre le risque de contamination L'invention concerne un dispositif autonome permettant de produire un faisceau d'air à flux laminaire horizontal ultra propre à température et hygrométrie maîtrisées, sur le champ d'une zone sensible à la contamination, au moyen d'un circuit d'air en forme de « C » couché horizontal, ouvert sur le faisceau d'air à flux laminaire et suspendu à une structure quelconque. Sous le faisceau, un plan relié au circuit permet de disposer d'un support à un acte médical ou chirurgical, à la recherche, à la production de produits industriels en continu ou de produits de hautes technologies. Des mâts fixés à l'intérieur du « C » couché horizontal entre les segments haut et bas et
