Title:
HUMIDIFYING AND PROTECTIVE ARRANGEMENT APPLIED TO A MASK
Document Type and Number:
WIPO Patent Application WO/2019/018912
Kind Code:
A1
Abstract:
A utility model pertaining to the technological sector of face masks, relating, especially, to a new humidifying and protective arrangement applied to a mask, providing practical, versatile and low-cost face masks that may or may not be disposable, and which are capable of humidifying inhaled air in a simple and economical manner without the use of external energy. The mask has a particulate filter composed of a fluid-retaining material and it may be recharged by the actual user in a simple manner, preferably with water or other fluids, having spaces that allow the entry of the inspired air such that the inhaled air containing oxygen enters the mask only via the humidifying filter. The masks may or may not be disposable, those that are re-usable being made from washable materials. Owing to the fact that the material of the humidifying filter can be replaced, for reasons of hygiene the filter may be removed from the base or body of the mask and replaced with another.
