[0007] According to an optional embodiment, the nose clip device includes a pressing rod with a threaded cylinder erected below a horizontally placed rectangular block, the upright cylinder being inserted into a socket on the respiratory filter mask body; a pressing head that is overall in the shape of an ellipsoid and has a threaded groove in the center; and a pair of nose clips that are fixed to the respiratory filter mask body and are overall in a Y shape.

[0008] According to an optional embodiment, the pressing head is threadedly connected to the pressing rod through a central threaded groove, and the whole is close to the nose clip to control the opening and closing of the nose clip.

[0009] According to an optional embodiment, the proximal end of the breathing filter connecting tube is a hollow elliptical cylindrical mouthpiece for oral placement; the middle part is an internal depression with a diameter of 2 mm, in which a gasket is placed to prevent air leakage; the distal end is a hollow cylindrical cannula for inserting a lung function test instrument; and the entire interior of the breathing filter connecting tube contains an air filter for filtering the inhaled gas.

[0010] According to an optional embodiment, the ventilation device includes an external thread structure that is threadedly fixedly connected to the ventilation threaded hole of the respiratory filter mask body; and an air filter for filtering the inhaled gas.

[0011] According to an optional embodiment, the air cushion is distributed around the periphery of the respiratory filtering mask body.

[0012] The utility model provides a disposable respiratory filtering mask for lung function examination, which has the following technical effects: compared with a traditional mouthpiece for lung function examination, the disposable respiratory filtering mask for lung function examination solves the problem that the mouthpiece is easy to fall off by adding a mask body and an elastic band, and adds a nose clip device in the mask body to solve the problem that the nose clip falls off during the patient's forced exhalation during the lung function examination due to the nose clip being worn alone, resulting in air leakage.
