[0002] The main purpose of sputum suction is to clean the respiratory tract secretions, keep the respiratory tract unobstructed, promote the improvement of respiratory function and pulmonary ventilation, and prevent the occurrence of complications such as aspiration pneumonia, dyspnea, cyanosis, and even asphyxia. In addition, sputum suction can also help diagnose the pathogens of pulmonary infections because the aspirated sputum can be sent for inspection to determine the source of infection. In some cases, sputum suction can also be used as a means of drainage to help control infectious diseases. Often, during sputum suction, the sputum suction tube is bitten, and the position of the sputum suction tube is not easy to move.

[0003] Regarding sputum suction devices, there are many existing technologies, for example:

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] The main purpose of sputum aspiration is to clear respiratory tract secretions, maintain airway patency, promote respiratory function, improve pulmonary ventilation, and prevent complications such as aspiration pneumonia, dyspnea, cyanosis, and even asphyxia. In addition, sputum aspiration can also help diagnose the pathogens of pulmonary infections because the aspirated sputum can be sent for examination to determine the source of infection. In some cases, sputum aspiration can also be used as a means of drainage to help control infectious diseases. It is often encountered that the patient bites the sputum aspiration tube and the position of the sputum aspiration tube is not easy to move during sputum aspiration.

[0026] Please refer to Figures 1 - 5As shown in the figure, this embodiment provides a multi-stage adjustable portable sputum suction device, including a hose 1. An annular groove 111 is provided inside the hose 1. In order for the hose 1 to move its position, specifically as follows: A threaded joint 11 is fixedly connected to the end of the hose 1. An annular plate 27 is provided inside the hose 1. The outer surface of the annular plate 27 is slidably connected to the inner surface of the hose 1. One end of the annular plate 27 is fixedly connected to one end of a cylindrical rod 2. The other end of the annular plate 27 is fixedly connected to a visible sputum suction mirror 28. The other end of the cylindrical rod 2 is fixedly connected to a square block 21. The movement of the square block 21 drives the movement of the cylindrical rod 2. Through the movement of the cylindrical rod 2, the hose 1 and the visible sputum suction mirror 28 are driven to move to determine the position of the sputum. However, during the sputum suction process of existing sputum suction devices, some children and some patients with cerebral hemorrhage are unable to cooperate as required by doctors or family members, bite the sputum suction tube, and there is no visible mirror to see the sputum inside the body, and they can only rely on experience. Some lack of experience may lead to incomplete suction. In addition, in order not to scratch the throat during the sputum suction process, the tube is relatively soft and cannot be moved and adjusted to the desired position, resulting in limited application scope.

[0027] The improvement of this embodiment lies in:

[0028] By moving the square block 21, the cylindrical rod 2, the annular plate 27 and the visible sputum suction mirror 28 are driven to move. By moving the cylindrical rod 2, the position of the hose 1 is driven to move. By rotating the handle 25, the rotating shaft 24 is driven to rotate. By rotating the rotating shaft 24, the fixed plate 22, the side plate 222, the rotating rod 221 and the square block 21 are driven to rotate back and forth. By rotating the square block 21, the cylindrical rod 2 moves back and forth, realizing the convenience of the forward and backward movement of the cylindrical rod 2. By sliding the armrest 32 left and right in the king-shaped groove 31, the square block 21 is driven to rotate left and right, realizing the left and right movement of the cylindrical rod 2 and improving the application scope.

[0029] In order to facilitate the forward and backward movement of the cylindrical rod 2, specifically, a rotating rod 221 is fixedly connected to the front and back sides of the square block 21. The outer surface of the rotating rod 221 is rotatably connected to a side plate 222. One end of the side plate 222 is fixedly connected to a fixed plate 22. A rotating shaft 24 is fixedly connected to the side of the fixed plate 22. The outer surface of the rotating shaft 24 is rotatably connected to a mounting plate 23. The other end of the rotating shaft 24 is fixedly connected to a handle 25. By rotating the handle 25, the rotating shaft 24 is driven to rotate. By rotating the rotating shaft 24, the fixed plate 22, the side plate 222, the rotating rod 221 and the square block 21 are driven to rotate back and forth. By rotating the square block 21, the cylindrical rod 2 moves back and forth, realizing the convenience of the forward and backward movement of the cylindrical rod 2.

[0030] In order to fix the forward and backward movement position of the cylindrical rod 2, specifically, a hole groove 241 is provided on the outer surface of the rotating shaft 24. The end of a U-shaped block 26 is slidably connected inside the hole groove 241. The other end of the U-shaped block 26 is fixedly connected inside the mounting plate 23. By fixing the U-shaped block 26 through the mounting plate 23 and fixing the rotating shaft 24 through the U-shaped block 26, the forward and backward movement position of the cylindrical rod 2 can be fixed.

[0031] Secondly, in order for the cylindrical rod 2 to move left and right, a rectangular plate 3 is fixedly connected to the right side of the mounting plate 23. A king-shaped groove 31 is formed on the outer surface of the rectangular plate 3. A handrail 32 is slidably connected inside the king-shaped groove 31. The end of the handrail 32 is fixedly connected to the right side of the square block 21. By sliding the handrail 32 left and right in the king-shaped groove 31, the square block 21 is driven to rotate left and right, realizing the left and right movement of the cylindrical rod 2.

[0032] Considering that some patients bite the flexible tube 1, an oral protector 29 is slidably connected to the outer surface of the flexible tube 1. By using the oral protector 29 to open the mouth, it is ensured that the patient cannot bite the flexible tube 1.

[0033] In summary, the working principle of this solution is as follows:

[0034] Put the oral protector 29 into the patient's mouth, manually insert the flexible tube 1 towards the throat. When approaching the sputum position, insert the end of the visual sputum aspirator 28 into the flexible tube 1 from inside the threaded joint 11. Determine the sputum position through the image captured by the visual sputum aspirator 28. At this time, hold the rectangular plate 3 with one hand and manually press the handrail 32 towards the inside of the throat with the other hand. Drive the square block 21, the cylindrical rod 2 and the annular plate 27 downward through the handrail 32. Drive the flexible tube 1 downward to the sputum height by clamping the annular plate 27 at the end of the flexible tube 1. Drive the cylindrical rod 2 and the annular plate 27 to move through the movement of the square block 21. Drive the flexible tube 1 to move its position through the movement of the cylindrical rod 2. Drive the rotation of the fixed plate 22, the side plate 222, the rotating rod 221 and the square block 21 back and forth through the rotation of the handle 25. Drive the cylindrical rod 2 to move back and forth through the rotation of the square block 21, realizing the convenience of the back and forth movement of the cylindrical rod 2. After determining the front and back positions of the sputum and stopping at the ideal position, manually insert the U-shaped block 26 into the hole groove 241 and the rectangular plate 3 at this time. Fix the U-shaped block 26 through the mounting plate 23, and fix the rotating shaft 24 through the U-shaped block 26, realizing that the back and forth movement position of the cylindrical rod 2 can be fixed. At this time, determine the left and right position of the sputum again through the image transmitted back by the visual sputum aspirator 28. Drive the square block 21 to rotate left and right by sliding the handrail 32 left and right in the king-shaped groove 31, realizing the left and right movement of the cylindrical rod 2. After aligning the flexible tube 1 with the sputum, hold the flexible tube 1 with one hand and keep it still, and pull out the rectangular plate 3 from inside the flexible tube 1 with the other hand. Thread the threaded joint 11 tightly onto the sputum aspirator, and then sputum aspiration can be performed. After use, manually unscrew the threaded joint 11 from the sputum aspirator, which is convenient for storage, improves the sputum aspiration accuracy, sucks more cleanly, and expands the scope of application.
