Cyclic device limiting the risks of contamination in certain devices installed in a hospital environment

摘要

The invention relates to a device which can be fitted to any apparatus which receives or treats contaminated waste in any manner (compressing, crushing, storing). The aim of the invention is to create in the chamber of these apparatuses, at the time of their loading, a slight reduction in atmospheric pressure. This pressure reduction limits turbulence and air flow which could convey contaminated micro-organisms which are undesirable for the ambient medium to the outside. The device consists of a fan 1, a diaphragm 5 neutralising smells and a micrometric filter 4. The apparatus is thus independent of any room fitted with a drainage pipe. The device according to the invention is intended in particular for a hospital environment and in particular apparatuses installed in departments (recovery, surgery, maternity, laboratory, etc.). In general it may be extended to the industrial environment and to any sector of activity which requires the same hygiene criteria. IMAGE
