However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides an interface for a sputum suction device, comprising a negative pressure device 1 and a connecting tube 2, the negative pressure device 1 is provided with a suction port 3, the suction port 3 is provided with a primary connecting end 4, a secondary connecting end 5, a tertiary connecting end 6 and a quaternary connecting end 7, a fixing ring 8 is sleeved and fixed on the surface of one end of the connecting tube 2, and two Velcro strips 9 are symmetrically fixed on the surface of the negative pressure device 1.

[0022] The effect achieved by the entire embodiment 1 is that when installing the connecting tube 2, with the cooperation of the first-level connecting end 4, the second-level connecting end 5, the third-level connecting end 6, and the fourth-level connecting end 7, the end of the connecting tube 2 mounted on the suction port 3 can be snapped into a position adapted thereto, so that the interface of the suction port 3 has high versatility and can be compatible with various types of suction tubes and suction equipment. The Velcro 9 can cooperate with the fixing ring 8 to further restrict the connecting tube 2 after the connecting tube 2 and the suction port 3 are plugged in, so as to prevent the connecting tube 2 from being detached due to accidental contact by active personnel, and with the setting of the Velcro 9, personnel can also remove the connecting tube 2 simply and quickly.

[0023] Embodiment 2, as Figure 1-Figure 4As shown, the negative pressure device 1 is provided with a plug terminal 10, a pressure gauge 11, an adjusting button 12 and a bottle body 13, and the suction port 3 is arranged on the bottle body 13; one end of the two Velcro strips 9 is a hook surface 901, and the other end is a sticky surface 902, the two hook surfaces 901 are fixed on the surface of the bottle body 13, and the sticky surface 902 ends of the two Velcro strips 9 pass through the fixing ring 8 and are respectively adhered to the corresponding hook surfaces 901; the cross-sections of the secondary connecting end 5, the tertiary connecting end 6 and the quaternary connecting end 7 are all trapezoidal, and a limiting ring 14 is arranged on the surface of the primary connecting end 4; the diameter of the primary connecting end 4 is smaller than the diameter of the secondary connecting end 5, the diameter of the secondary connecting end 5 is smaller than the diameter of the tertiary connecting end 6, and the diameter of the tertiary connecting end 6 is smaller than the diameter of the quaternary connecting end 7; the connecting pipe 2 is a hose, and a clamping ring 15 is fixed to the inner wall of one end of the connecting pipe 2 close to the fixing ring 8.

[0024] The effect achieved by the entire embodiment 2 is that the Velcro 9 can further restrict the connecting tube 2 from both sides after the connecting tube 2 and the suction port 3 are plugged in, so that the connecting tube 2 can be installed on the negative pressure device 1 more firmly, to prevent the connecting tube 2 from being detached due to accidental contact by active personnel, and will not delay the removal of the connecting tube 2 by personnel.
