Detailed Description
The present invention will be further described with reference to the following examples and accompanying drawings.
As shown in fig. 1, a mouse sputum aspirator comprises a face mask 3, wherein the face mask 3 is cylindrical, one end of the face mask 3 is open, and the other end is closed. The mask is characterized in that a sleeve 2 is arranged in the mask 3, the sleeve 2 is arranged along the axial direction of the mask 3, the inner end of the sleeve 2 extends to the opening of the mask 3, the outer end of the sleeve 2 penetrates out of the mask 3, and the pipe wall of the sleeve 2 is fixedly connected with the mask 3. A sputum suction pipe 4 is movably arranged in the sleeve 2 in a penetrating manner, one end of the sputum suction pipe 4 is an extending end, the other end of the sputum suction pipe is a suction end, the extending end extends out of the inner end of the sleeve 2, and the suction end is connected with a suction device 5.
Arc breach 3a has been seted up to the open end of face guard 3, and this arc breach 3a suits with the mouse neck, and this arc breach 3a forms the region of stepping down.
The inner end of the sleeve 2 is connected with two chewing bars 2a, the two chewing bars 2a are distributed on two sides of the sleeve 2, and the two chewing bars 2a are parallel to the end connecting line direction of the arc-shaped gap 3 a.
