[0020] The following will be combined with the attached embodiment of the utility model Figure 1-Figure 4 , the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0021] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0022] like Figure 1 , a sputum suction device, comprising a liquid collection chamber 1, a connecting shell 4, a fixed tube 2 and a rotating tube 6;

[0023] The top of the liquid storage bin 1 is detachably connected to the connecting shell 4, and the top of the connecting shell 4 is fixedly connected to the fixed tube 2; one end of the fixed tube 2 is inserted into the liquid storage bin 1, and the other end thereof is rotatably connected to the rotating tube 6 through a connecting mechanism 7, so that the open end of the rotating tube 6 faces upward or downward, and the rotating tube 6 is used to connect the drainage tube;

[0024] The outer side surface of the connecting shell 4 is fixedly connected to a negative pressure pipe 5 for suction.

[0025] When suctioning sputum, the open end of the rotating tube 6 is set downward, and it can be connected to the drainage tube by plugging, snapping, etc. The drainage tube is a prior art, which is used to attract sputum in the patient's mouth and throat. The negative pressure tube 5 can be connected to a corresponding negative pressure device, such as an air pump, a manual suction air bag, etc. After the open end of the rotating tube 6 is set downward, the negative pressure device is turned on, and under the action of negative pressure, sputum is sucked into the effusion bin 1 for accumulation. When the effusion bin 1 needs to be cleaned, the rotating tube 6 can be rotated so that its open end is facing upward, and the open end is connected to the corresponding flushing water pipe, flushing head and other equipment. The flushing water is flushed from top to bottom through the rotating tube 6 and the fixed tube 2 in the effusion bin 1 to complete the cleaning. Compared with the prior art, the utility model controls the different directions of the rotating tube 6 by rotating. When its opening is facing downward, it is convenient to carry out suction operations and facilitate sputum to enter the effusion bin 1. When the opening of the rotating tube 6 is facing upward, a flushing operation can be carried out, so that the flushing water moves from top to bottom to avoid the backflow of the flushing water. The utility model provides two different working modes for two working scenarios of sputum suction and flushing. By using the rotating tube 6 and the fixed tube 2 in coordination, sputum reflux can be effectively avoided, making the sputum suction and flushing processes safer and more hygienic.

[0026] Further, one end of the fixed tube 2 inserted in the fluid storage bin 1 is located below the negative pressure tube 5. Such a design can prevent the negative pressure tube 5 from sucking out sputum, so that the negative pressure tube 5 only generates negative pressure without sucking away sputum.

[0027] Furthermore, one end of the fixed tube 2 inserted in the liquid storage bin 1 is fixedly connected to the sieve cylinder 3, and the opening of the sieve cylinder 3 is arranged downward. The surface of the sieve cylinder 3 is a grid mesh structure, and the sputum enters the sieve cylinder 3 through the fixed tube 2, thereby preventing the sputum from splashing.

[0028] Furthermore, both the fixed tube 2 and the rotating tube 6 are "L"-shaped structures.

[0029] Specifically, Figure 1 When the open end of the rotating tube 6 faces downward, the rotating tube 6 and the fixed tube 2 together form an arch structure, which can prevent sputum from flowing back.

[0030] Furthermore, the connecting mechanism 7 includes a clamping ring 701 and a screw 702; one end of the rotating tube 6 and the fixed tube 2 connected thereto is respectively provided with an adaptable flange portion, and the two clamping rings 701 clamp the flange portion thereof, and the two clamping rings 701 are respectively provided with an adaptable semicircular hole 704, and the semicircular hole 704 is coaxially distributed with the clamping ring 701, and the screw 702 is connected in the semicircular holes 704 of the two clamping rings 701.

[0031] Specifically, the screw rod 702 passes through the semicircular holes 704 on the two clamping rings 701, and corresponding nuts can be set at both ends of the screw rod 702 to lock the two clamping rings 701 and retain a certain degree of rotation. The semicircular hole 704 plays a limiting function, so that the two clamping rings 701 can only rotate 180° relative to each other, so the rotating tube 6 can only rotate 180°, so that its opening faces upward or downward. The flange part has a flange structure and is distributed in the circumferential direction around the end face of the rotating tube 6 / fixed tube 2. The clamping ring 701 and the flange part can be fixedly connected or detachably connected by screws.

[0032] Furthermore, a sealing ring 703 is provided between the two flange parts, and the sealing ring 703 realizes an airtight function. A corresponding annular groove can be provided between the two flange parts so that the sealing ring 703 is clamped in the annular groove.

[0033] Furthermore, the connecting shell 4 is a funnel structure, and the inner diameter of the lower end is larger than the inner diameter of the upper end.

[0034] Furthermore, a drain port 8 is provided at the bottom of the liquid storage bin 1, and a corresponding valve can be provided on the drain port 8 to discharge sputum or flushing water.

[0035] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations, modifications, and substitutions made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
