Diffusion cap for surgical unit in hospital, has porous wall diffusing laminar air flow, and compensation area forming angle with horizontal component so as to diffuse air in direction of zone located under area of porous wall

摘要

The cap (3) has a porous wall (11) diffusing a laminar air flow. The porous wall includes an area that is intended to be in close relationship with an upper face (20) of a suspended equipment i.e. turntable (13). A compensation area forms an angle with a horizontal component so as to diffuse air in the direction of a zone located under the area of the porous wall. A marginal area is located beyond the compensation area with regard to the area of the porous wall. A transition area is arranged between the compensation area and the marginal area. Independent claims are also included for the following: (1) a method for diffusing air through a porous wall (2) a surgical unit.
