Description

Technical Field

[0001] This utility model belongs to the technical field of airway auxiliary treatment instruments, and specifically relates to an airway sputum ring suction device. Background Technology

[0002] In the field of airway support technology, airway management is a crucial aspect of intensive care, anesthesia, and respiratory therapy, especially for patients on mechanical ventilation after the establishment of an artificial airway. The accumulation and clearance of sputum directly affect ventilation effectiveness and infection control. Traditional endotracheal tubes primarily function to maintain airway patency and provide ventilation support, but their relatively simple structure often lacks an integrated effective sputum drainage device. Frequent suctioning is clinically necessary to prevent sputum plug formation, reduce the risk of pulmonary infection, and maintain airway patency.

[0003] Currently, the common method of sputum suctioning involves inserting a separate suction catheter deep into the airway via an endotracheal tube and applying negative pressure. While this procedure is effective in removing secretions, it also has significant drawbacks. First, repeated insertion of the suction catheter can easily cause mechanical damage to the airway mucosa, leading to bleeding or edema. Second, the ventilator connection needs to be disconnected during the procedure, which can result in interrupted ventilation and decreased oxygenation, posing a certain risk, especially for critically ill patients.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an airway sputum ring suction device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an airway sputum ring suction device, comprising a tracheal tube. The tracheal tube has a suction chamber and an inflation chamber within its wall. Both ends of the inflation chamber and the suction chamber are connected to the side surface of the tracheal tube on which it is installed. A balloon and a suction ring are fixedly mounted on the tracheal tube. An inflation tube is disposed within the inflation chamber. One end of the inflation tube passes through the inflation chamber and is connected to the inner cavity of the balloon. The other end of the inflation tube extends out of the inflation chamber and is connected to an inflation connector. The inner ring of the suction ring is fixedly sealed to the side surface of the tracheal tube, and the inner ring has an opening area. The suction ring has several suction holes. One end of the suction chamber is located in the opening area where it communicates with the side surface of the tracheal tube. A suction tube is disposed within the suction chamber. One end of the suction tube communicates with the opening area of ​​the suction ring, and the other end extends out of the suction chamber and is connected to a suction connector.

[0007] Furthermore, the endotracheal tube has a support groove near the end where the balloon is located, a camera is installed in the groove, and a wire cavity is opened in the wall of the endotracheal tube. One end of the wire cavity is connected to the side surface of the endotracheal tube, and the other end is connected to the support groove. A data cable for connecting the camera is installed in the wire cavity.

[0008] Furthermore, two symmetrically arranged water cavities are formed inside the wall of the tracheal tube, with one end of each water cavity communicating with the side surface of the tracheal tube and the other end communicating with the end face of the tracheal tube near the camera. The openings of the two water cavities near the camera are respectively located above the camera lens. A flushing tube is provided inside each water cavity, with one end of the flushing tube located at the opening of the water cavity near the camera and the other end extending from the side surface of the tracheal tube to the outside.

[0009] Furthermore, a machine end connector is provided at the end of the endotracheal tube furthest from the camera.

[0010] Furthermore, the suction ring is located between the balloon and the machine end connector, and is close to the balloon.

[0011] This utility model has the following beneficial effects: This invention, through the design of a balloon, suction ring, and suction hole, can reduce the risk of airway damage during endotracheal tube insertion after sputum production. This method also allows for more convenient sputum removal. Furthermore, the design of the suction ring, suction hole, and suction tube allows for annular drug administration into the airway, making airway drug administration more convenient.

[0016] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0017] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0018] Please see Figures 1-2 As shown, this utility model is an airway sputum ring suction device, including a tracheal tube 1. The tracheal tube 1 has a suction chamber and an inflation chamber inside its wall. Both ends of the inflation chamber and the suction chamber are connected to the side surface of the tracheal tube 1 on which it is installed. A balloon 2 and a suction ring 4 are fixedly installed on the tracheal tube 1. An inflation tube 3 is disposed inside the inflation chamber. One end of the inflation tube 3 passes through the inflation chamber and is connected to and fixedly connected to the inner cavity of the balloon 2. The other end of the inflation tube 3... The other end of the air chamber is connected to an air inflator. The inner ring of the suction ring 4 is fixedly sealed to the side surface of the endotracheal tube 1, and the inner ring of the suction ring 4 has an opening area. The suction ring 4 is provided with several suction holes 7. One end of the suction chamber is connected to the side surface of the endotracheal tube 1 at the opening area. A suction tube 5 is provided in the suction chamber. One end of the suction tube 5 is connected to the opening area of ​​the suction ring 4, and the other end extends out of the suction chamber and is connected to a suction inflator 6.

[0019] After the endotracheal tube 1 is inserted into the airway through the human mouth, the balloon 2 is inflated by the inflation tube 3, so that the balloon 2 expands and fits into the airway, thereby fixing the endotracheal tube in the airway. Since the balloon 2 adheres to the airway wall inside the airway, sputum usually accumulates. Therefore, a suction ring 4 is provided near the balloon 2. The opening area of ​​the suction ring 4 is connected to the suction tube, and the open end (i.e. the external end) of the suction tube 5 is connected to a controllable negative pressure device. This allows the controllable negative pressure device to create suction force on the opening area through the suction tube 5, so that the accumulated sputum enters the opening area through the suction hole 7 and is then discharged from the airway through the suction tube 5, thus avoiding airway infection caused by sputum contact. By designing the balloon 2, suction ring 4, and suction port 7, the risk of airway damage during endotracheal tube intubation can be reduced after sputum production and suctioning. This method also allows for more convenient sputum removal. Furthermore, the design of the suction ring 4, suction port 7, and suction tube 5 allows for ring-shaped drug administration into the airway through this channel, making airway drug administration more convenient.

[0020] In one embodiment, for the tracheal tube 1, a slot 8 is provided at the end of the tracheal tube 1 near where the balloon 2 is provided, a camera 9 is provided in the slot 8, and a wire cavity is opened in the tube wall of the tracheal tube 1. One end of the wire cavity is connected to the side surface of the tracheal tube 1, and the other end is connected to the slot 8. A data cable for connecting the camera 9 is provided in the wire cavity 8.

[0021] The lens of camera 9 is coated with a nano-coating to further reduce the adhesion of sputum to the lens of camera 9 during intubation.

[0022] Camera 9 is mainly used for airway intubation under visual guidance. The camera is connected to an external display screen via a data cable (including a USB connector) to enable visual guidance and facilitate intubation.

[0023] In one embodiment, for the tracheal tube 1, two symmetrically arranged water cavities are formed inside the tube wall of the tracheal tube 1. One end of each water cavity is connected to the side surface of the tracheal tube 1, and the other end is connected to the end face of the tracheal tube 1 near the camera 9. The openings of the two water cavities near the camera 9 are respectively located above the mirror surface of the camera 9. A flushing pipe 10 is provided inside each water cavity. One end of the flushing pipe 10 is located at the opening of the water cavity near the camera 9, and the other end extends from the side surface of the tracheal tube 1 to the outside.

[0024] During the intubation of the endotracheal tube 1, a small amount of sputum will be on the lens surface of the camera 9. Cleaning fluid is dripped onto the lens surface of the camera 9 through the flushing tube 10 to clean the lens surface. The waste liquid generated during the cleaning process is directly suctioned out through other suction tubes inserted into the endotracheal tube 1. At the same time, other sputum generated in the airway (located on the other side of the balloon) is also suctioned out.

[0025] In one embodiment, for the endotracheal tube 1, a machine end connector 11 is provided at the end of the endotracheal tube 1 away from the camera 9, and the machine end connector 11 is used to connect to an external ventilator.

[0026] In one embodiment, the suction ring 4 is located between the balloon 2 and the machine end connector 11, and is close to the balloon 2.
