PORTABLE RESPIRATORY VIRUS PROTECTION DEVICE Russian patent published in 2022 - IPC A62B18/02 A62B18/08 A62B18/10 

FIELD: portable protective devices.

SUBSTANCE: inventions group relates to portable protective devices for protection against respiratory viruses. In accordance with the first embodiment, the portable protective device includes a face shield, a respiratory guide, an air cleaner, a fastening tape, an insertion port for inserting a straw, and a cap. The face shield is adapted to be worn on the user's face so as to cover the user's eyes, nose, and mouth. The face shield has an air inlet for taking outside air in at its top and has an air channel formed around its edge to form a channel through which air is expelled to the outside when the user breathes. The respiratory rail is attached to surround the back of the face shield, comes into close contact with the user's face, and has a diaphragm at its center to separate the user's eyes and respiratory organs. An air cleaner connected to the air inlet at the top of the face shield cleans and supplies outside air to the air inlet. The fastening tape is connected to the back of the face shield to be worn on the back of the wearer's head. An insertion port for inserting a straw allowing the user to consume a drink is formed at the bottom of the face shield. The cap opens/closes the insertion port. An air intake hole is formed on the diaphragm so that the air, purified by the air cleaner, can flow to the respiratory organs of the user through the air inlet. A non-return valve is installed inside the diaphragm, which opens the air intake hole when the user inhales and closes the air intake hole when the user exhales. In accordance with the second embodiment, the portable protective device, instead of a plug-in port and a cap, contains a mouth shield connected to the lower part of the face shield and enclosing the user's mouth from the external environment, made rotatable, while the face shield is adapted to be worn on the user's face so as to cover the eyes and the user's nose, and has an air inlet for taking outside air in at the top of it.

EFFECT: inventions allow the user to consume drinks and food while minimizing the risk of exposure to respiratory viruses.
