Fluid Unidirectional Flow Structure, Check Assembly, and Respiratory Device

Abstract

Disclosed is a fluid unidirectional flow structure. The fluid unidirectional flow structure (100) comprises; a first flow-checking body (110) and a second flow-checking body (120); the first flow-checking body (110) comprises a first connection portion (111) that is interconnected with a first flow portion (112) having at least one first through-hole (113); the second flow-checking body (120) comprises a second connection portion (121) interconnected with a second flow portion (122) having at least one second through-hole (123); when a fluid reverses directions, at least part of the first flow portion (112) moves relative to at least part of the second flow portion (122). The fluid unidirectional flow structure (100) may be designed in any shape, so as to facilitate installation. Also disclosed are a check assembly, and a respiratory device, when used on a breathing passageway, the invention may be adapted to a respiratory passageway of any size and shape. The fluid unidirectional flow structure (100) may also be installed on the body of a respiratory isolation mask (1000), wherein the shape of said mask may be adapted to the shape of the face of a person or animal. The shape of the first flow-checking body (110) and of the second flow-checking body (120) may be configured to be adaptable, so as to better bring into play the function and utility of the fluid unidirectional flow structure.
