Description

Technical Field

[0001] This utility model relates to the technical field of expectoration training devices, and in particular to an expectoration training device for patients with COPD. Background Technology

[0002] COPD is a common lung disease characterized by airflow limitation, usually caused by factors such as prolonged smoking, air pollution, and occupational exposure. COPD patients often cough up sputum, especially thick sputum. A cough training device is a device used to help COPD patients clear sputum from their airways. These devices can help patients expel sputum more effectively by simulating a cough or providing airflow, thereby improving respiratory function and reducing the risk of infection.

[0003] However, some existing cough training devices used by COPD patients typically clear sputum from the airways by vibrating the airflow. But the vibrations generated by the airflow are usually not adjustable, which reduces the effectiveness of sputum clearing during use. In addition, they are inconvenient to carry around, which reduces the convenience of the device. Furthermore, the membrane inside that generates air vibrations is easily damaged when not in use, which also reduces the lifespan of the device. Therefore, these problems need to be solved. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cough training device for COPD patients.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A fixing shaft is fixedly connected to the top of the guide plate. The two ends of the fixing shaft are rotatably connected to opposite sides inside the housing. A rotating mechanism for rotating the fixing shaft is provided inside the housing. A knob allows for easy rotation of the fixing shaft and guide plate during use, thereby controlling the airflow inside the housing and thus the frequency of vibration of the membrane inside the housing. This improves the effectiveness of the device. Furthermore, rotating the protective sleeve enhances the device's convenience and also rotates the barrier plate, thus restricting the membrane's movement.

[0007] Preferably, the sliding mechanism includes a limiting block, a limiting ring is fixedly connected to one end of the sliding sleeve, the limiting ring is slidably sleeved on the outer surface of the fixed ring, two limiting grooves are horizontally opened on the surface of the fixed ring, and limiting blocks are slidably connected inside each of the two limiting grooves.

[0010] Furthermore, a protective sleeve is provided on the surface of the outer shell, and the protective sleeve is rotatably fitted onto the outer surface of the outer shell.

The barrier plate cooperates with one end of the horizontal plate to restrict the rotation of the protective sleeve on the surface of the outer shell, and at the same time, it will drive the connecting shaft and the barrier plate inside the outer shell to rotate.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. When in use, the protective cover can be rotated so that it is perpendicular to the outer shell surface. At the same time, the connecting shaft and the barrier plate inside the shell will also rotate, which can loosen the film surface. Then, the suction nozzle can be inserted into the fixing ring for use. Alternatively, when not in use, the barrier plate can be used to press the film against one end of the horizontal plate to improve the protective effect on the film.

This controls the vibration frequency of the membrane. The smaller the airflow gap, the greater the vibration frequency, thus improving the performance of the device. Attached Figure Description

[0028] In this utility model, a protective sleeve 2 is provided on the surface of the outer shell 1. The protective sleeve 2 is rotatably fitted on the outer surface of the outer shell 1.

[0029] Working Principle: In actual use, the knob 4 allows for easy rotation of the fixed shaft 31 and the guide plate 3, thereby controlling the airflow inside the outer casing 1. This controls the frequency of vibration of the diaphragm 33 inside the outer casing 1, improving the device's effectiveness. Combined with the rotation of the protective sleeve 2, the device's convenience is enhanced. Simultaneously, the barrier plate 23 rotates, further restricting the diaphragm 33. When in use, the protective sleeve 2 can be rotated until it is perpendicular to the surface of the outer casing 1. This rotation also causes the connecting shaft 22 and the barrier plate 23 inside the outer casing 1 to rotate, loosening the diaphragm 33. The suction nozzle 5 can then be inserted into the fixing ring 16 for use. During use, the suction nozzle 5 should be placed against the mouth area, and air should be inhaled. External air enters the housing 1 through the protective cover 13 and flows in through the bottom of the guide plate 3. When the air passes over the surface of the membrane 33, it causes the membrane 33 to vibrate, which in turn causes the air to be drawn in. The vibration of the air effectively relieves coughing. During use, the knob 4 can be manually rotated. The rotation of the knob 4 is positioned by the cooperation of multiple second magnetic blocks 41 and first magnetic blocks 110. At the same time, under the connection of the connecting column 32, the fixed shaft 31 and the guide plate 3 will rotate simultaneously, which can control the gap between the bottom of the guide plate 3 and the inside of the housing 1, thereby controlling the amount of airflow inside the housing 1 and thus controlling the vibration frequency of the membrane 33. The smaller the airflow gap, the greater the vibration frequency.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
