Breather valve and application method thereof

Abstract

The invention discloses a breather valve and an application method thereof. The breather valve comprises a breather tube, a valve plate and a return spring; the valve plate is disposed within the breather tube; the return spring used for returning the valve plate is disposed within the breather tube. The return spring allows the valve plate to be returned in time when a patient breathes, sealing is insufficient, and no leakage occurs.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a breathing ventilation valve and a method for using the same. Background technique [0002] Such as figure 1 as shown, figure 1 is a perspective view of an existing respiratory ventilation valve, widely used in respiratory mask equipment, combined with figure 2 as shown, figure 2 It is a cross-sectional view of an existing breathing ventilation valve. A valve piece 140 is movable between the gas suction port 110 and the gas discharge port 120. The middle part of the valve piece 140 is stuck on the breathing ventilation valve body, and is restored by the pressure of the inhaled gas and its own recovery. The force swings back and forth between the gas suction port 110 and the gas discharge port 120 . [0003] When the patient is inhaling, the gas is inhaled by the gas suction port 110, and the valve plate 140 is separated from the gas suction port 110 under the act...
