DETAILED DESCRIPTION

[0025] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects according to the utility model are described in detail as follows by combining with the drawings and preferred embodiments.

[0026] Referring to Figures 1-7 A sputum suction device for pneumology department, comprising a host computer 1 and a cannula 3, the cup hole 101 is installed on the host computer 1, the storage cup 2 is placed in the cup hole 101, the negative pressure interface 204 of the storage cup 2 is connected with the negative pressure system of the host computer 1 through the negative pressure pipeline, and the sputum suction interface 205 of the storage cup 2 is connected with the cannula 3 through the sputum suction tube.

[0027] During use, the cannula 3 is installed at the end of the suction tube, and then the cannula 3 is inserted into the patient's throat and trachea, and then the suction operation is performed. The suction operation can be realized with existing technology and will not be elaborated here. In this solution, the cannula 3 can prevent the sputum in the suction tube from flowing back, and compared with the suction pipe in the existing technology, in this solution, the suction pipe is actually composed of the cannula 3 and the suction pipe. The cannula 3 is in contact with the patient's saliva and other body fluids in the mouth, and the suction pipe is not extended into the patient's mouth, so it does not come into contact with the patient's saliva and other body fluids in the mouth, and the sputum in the suction tube will not flow back, so the cannula 3 can be set to be disposable, and the sputum suction of different patients can be achieved by replacing the cannula 3, which is less costly. Example

[0028] Reference Figure 4 The detachable connection between the cannula 3 and the suction tube can be: the cannula 3 is made of materials such as rubber or silicone, has elastic deformation ability, and has an interference fit with the suction tube, so the cannula 3 can be directly plugged into the suction tube, making disassembly and assembly more convenient and quick.

[0029] A baffle member extends from the inner wall of the cannula 3 and is arranged in an array along the axis of the cannula 3. The baffle member includes two arc-shaped baffles 302 arranged on the inner wall of the cannula 3. The baffles 302 are made of soft material, such as rubber or silicone. The connection positions of the two baffles 302 and the inner wall of the cannula 3 are respectively located on both sides of the axis of the cannula 3. The maximum distance between the side of the baffle 302 away from the connection position and the connection position is slightly greater than the inner radius of the cannula 3. In this way, Figure 4 As shown, the dotted line represents the axis of the cannula 3, and the baffle 302 slightly exceeds the dotted line. During suction, due to the negative pressure, the baffle 302 will be offset toward the side of the suction tube, and the sputum can pass through the baffle 302, and the suction is carried out normally without being affected. After the suction is completed, the negative pressure disappears, the rubber or silicone has a certain elasticity, and the baffle 302 is restored. At this time, the sputum in the suction tube is blocked by the baffle 302 and cannot pass through multiple baffles 302. Therefore, it can prevent sputum reflux.

[0030] Preferred embodiment, see Figure 3 A convex plate 301 extends from the tube opening of the cannula 3 for connecting to the suction tube. During the suction operation, the convex plate 301 is directed downward. In this way, if the medical staff accidentally lets go due to fatigue or other reasons, the convex plate 301 will prevent the cannula 3 from excessively extending into the patient's throat, thereby achieving a protective purpose. In addition, the presence of the convex plate 301 can also remind the medical staff to keep the convex plate 301 close to the patient's mouth to prevent the suction tube behind the convex plate 301 from being contaminated by saliva in the patient's mouth. Example

[0031] Reference Figures 5-7, the storage cup 2 comprises a cup body composed of a plurality of coaxially screwed cup bodies 201, an opening of the cup body is coaxially screwed with a cup cover 202, another opening of the cup body is coaxially screwed with a cup bottom 203, and a negative pressure interface 204 and a sputum suction interface 205 are arranged on the cup cover 202; the advantage of the detachable split type of the storage cup 2 is that the storage cup 2 can be disassembled into segments for cleaning, each segment is short, convenient to wipe, more convenient to clean and disinfect, and the disassembly and assembly are also convenient and fast.

[0032] In a preferred embodiment, in order to avoid the influence of the sealing performance of the threaded connection of the storage cup 2 on the negative pressure and then on the sputum suction operation, referring to Figure 7 , the outer circular surface of the cup cover 202 is coaxially provided with a sealing ring 206, the bottom of the sealing ring 206 is inlaid with a magnet 207, referring to Figure 2 , the end surface of the main machine 1 provided with the cup hole 101 is further provided with an annular groove 102, the annular groove 102 is coaxial with the cup hole 101 and communicates with each other, the groove bottom of the annular groove 102 is inlaid with a magnet 103, the opposite poles of the magnet 103 and the magnet 207 are opposite, the storage cup 2 is placed in the cup hole 101 and the magnet 103 is aligned with the magnet 207, the sealing ring 206 is tightly attached to the groove bottom of the annular groove 102 by the magnetic attraction force between the two, and then during sputum suction, the negative pressure system is started, if the sealing performance of the threaded connection of the storage cup 2 is poor, then the negative pressure will cause the air in the cup hole 101 to enter the storage cup 2, the cup hole 101 is in a negative pressure state, and the sealing ring 206 is tightly attached to the groove bottom of the annular groove 102 under the action of negative pressure, so as not to affect the subsequent sputum suction operation.

[0033] In a preferred embodiment, referring to Figure 2 , the end surface of the main machine 1 provided with the annular groove 102 is further provided with an identification 104 close to the magnet 103, referring to Figure 5 , the upper end surface of the cup cover 202 is provided with an identification 208 located directly above the magnet 207, which means that the positions of the magnet 103 and the magnet 207 can be determined by the identification 104 and the identification 208, which facilitates the alignment between the two, in addition, a handle is arranged on the cup cover 202, when the storage cup 2 is taken away, the medical staff can hold the handle, rotate the storage cup 2 first, and then take the storage cup 2 upwards, which is more labor-saving when taking the storage cup 2.

[0034] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in any form. Although the present application has been disclosed with preferred embodiments, it is not intended to limit the present application. Any person skilled in the art can make minor changes or modifications to the disclosed technical content, or make equivalent embodiments with equivalent changes, without departing from the technical solution of the present application. Any modification, equivalent change or modification of the above embodiments, which does not depart from the technical solution of the present application, is still within the scope of the technical solution of the present application.
