[0023] A sputum suction tube of the utility model will be described in more detail below in conjunction with the accompanying drawings, wherein preferred embodiments of the utility model are shown. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the beneficial effects of the utility model. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation to the utility model.

[0024] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0025] like Figure 1 As shown, the embodiment of the utility model provides a convenient and practical sputum suction tube, comprising a suction tube 1, a bag 2, a sleeve 3 and a mouthpiece 4.

[0026] Specifically, the straw 1 includes an outlet end 10, a negative pressure connection end 11 and an inlet end 12; the outlet end 10 and the inlet end 12 are respectively located at the two ends of the straw 1; the negative pressure connection end 11 is close to the outlet end 10; the negative pressure connection end 11 is used to be connected to a negative pressure adsorption device; the bag 2 is connected to the outlet end 10; the mouthpiece 4 is installed on the sleeve 3 and is close to the inlet end 12; the straw 1 passes through the sleeve 3 and the mouthpiece 4, and is slidably connected to the sleeve 3 and the mouthpiece 4.

[0027] Preferably, the straw 1 is a Y-shaped structure. Further, the straw 1 is a hose.

[0028] In a specific example, the negative pressure connection end 11 and the outlet end 10 are both located at the top of the Y-shaped structure, and the inlet end 12 is located at the bottom of the Y-shaped structure. Furthermore, the negative pressure connection end 11 faces the direction opposite to the ground, and the angle between the negative pressure connection end 11 and the outlet end 10 is an obtuse angle; and the outlet end 10 faces the ground. In the process of sputum suction, by facing the bag 2 and the outlet end 10 to the ground and located below the negative pressure connection end 11, it is convenient for sputum to enter the suction tube 1 and enter the outlet end 10 smoothly under the influence of gravity, thereby flowing to the bag 2.

[0029] In this embodiment, a plurality of through holes 13 are provided on the side wall of the straw 1 close to the inlet end 12 .

[0030] Preferably, in order to improve the effect of suctioning phlegm, the end of the inlet end 12 may be provided with a curved surface. Those skilled in the art will appreciate that the end of the inlet end 12 may be shaped according to actual needs, for example, the end may be a curved surface, a flat surface, or other shapes.

[0031] In a specific example, the side wall of the straw 1 is connected to a limiting strip 5. Specifically, the limiting strip 5 is slidably disposed in the sleeve 3. The limiting strip 5 can prevent the straw 1 from directly sliding out of the sleeve 3, especially after the suction of sputum is completed, if the straw 1 directly slides out of the sleeve 3, sputum splashing is likely to occur.

[0032] In this embodiment, a protective film 6 is provided inside the negative pressure connection end 11 to allow gas to circulate and prevent liquid from circulating. The provision of the protective film 6 can prevent the negative pressure adsorption device from sucking sputum into the negative pressure connection end 11 when the negative pressure adsorption device is in use, thereby preventing the port of the negative pressure adsorption device from being blocked.

[0033] The protective film 6 is close to the outlet end 10 to prevent sputum from entering the negative pressure connection end 11 and facilitate the sputum to flow smoothly along the tube wall of the straw 1 and the protective film 6 to the outlet end 10 under the action of gravity, thereby reaching the pouch 2.

[0034] In one embodiment, the mouthpiece 4 is provided with a through hole 40. Specifically, the straw 1 passes through the through hole 40. After the sputum suction is finished, the inlet end 12 of the straw 1 can be retracted into the through hole 40 or the sleeve 3 by pulling the straw 1 to prevent the sputum from splashing out to the outside.

[0035] Preferably, the mouthpiece 4 is made of hard silicone.

[0036] In order to facilitate installation and disassembly, the mouthpiece 4 is detachably installed on the sleeve 3.

[0037] In addition, in this embodiment, the pouch 2 is connected to the outlet port 10 in a detachable manner.

[0038] In this embodiment, in the initial state, since the straw 1 is bendable, the outlet end 10 of the straw 1 and the pouch 2 can face the ground (to facilitate the sputum to slide smoothly into the pouch 2 under the action of gravity), and the inlet end of the straw 1 is located in the sleeve 3 or the through-hole 40. When the sputum suction operation is required, according to the actual situation, the mouthpiece 4 can be first stuck in the patient's mouth (or the straw 1 can be straightened to the throat first, and then the mouth can be stuck), and then the straw 1 can be slowly extended from the through-hole 40 to the throat. Start the negative pressure adsorption device, and the sputum in the patient's throat enters the straw 1 through the multiple through holes 13 and the inlet end 12, and slides into the pouch 2 under the action of negative pressure and gravity. After the sputum suction is completed, pull the straw 1, retract the inlet end 12 of the straw 1 into the sleeve 3 or the through-hole 40, and remove the mouthpiece 4.

[0039] In summary, the sputum suction tube proposed by the utility model has the following advantages:

[0040] Through the arrangement of a straw, a bag, a sleeve and a mouthpiece; and the straw includes an outlet end, a negative pressure connection end and an inlet end; the outlet end and the inlet end are respectively located at the two ends of the straw; the negative pressure connection end is close to the outlet end; the negative pressure connection end is used to be connected to a negative pressure adsorption device; the bag is connected to the outlet end; the mouthpiece is installed on the sleeve and is close to the inlet end; the straw passes through the sleeve and the mouthpiece, and is slidably connected to the sleeve and the mouthpiece. This device can achieve sputum suction, and collect sputum into the bag for unified treatment to avoid environmental pollution, and there is no need to use an additional sputum collection device to avoid waste of resources. This device can also avoid the opening and closing of the patient's mouth during the suction process to affect the position and use of the suction tube, thereby ensuring the effect of suction. In addition, this device can be used once, and there is no need to replace the bag regularly. It is not only simple, convenient and hygienic, but also environmentally friendly.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
