Description

Technical Field

[0001] This utility model relates to the field of breathing training device technology, and in particular to a breathing training device. Background Technology

[0002] Breathing trainers, especially three-ball stimulating breathing trainers, are medical devices widely used in clinical and home rehabilitation. Their main function is to guide users to perform continuous deep breathing exercises through visual feedback, thereby effectively expanding alveoli, preventing atelectasis, and improving lung function. They are particularly suitable for post-surgical patients and patients with respiratory diseases.

[0003] Existing three-ball breathing trainers typically consist of a main outer shell, a main airway, multiple bronchial airways (each corresponding to a different flow threshold), and a movable indicator piston or ball located inside the shell. When the user inhales through the mouthpiece or mask, the airflow passes sequentially through the main airway and bronchial airways. When the inspiratory flow rate reaches the design threshold of a specific bronchial airway, the corresponding indicator piston or ball rises to indicate the current inspiratory level.

[0004] However, existing products of this type often employ traditional methods for forming their internal airways, such as assembling multiple independent plastic components (e.g., pipes, connectors) within an inner shell. This multi-component assembly method leads to cumbersome manufacturing processes, low assembly efficiency, and the presence of numerous seams increases the risk of gas leakage, affecting the sealing reliability of the airway system and the accuracy of flow measurement. Therefore, there is an urgent need for an integrated breathing trainer with optimized structural design that can fundamentally simplify the assembly process, improve airtightness, ensure the regularity and smoothness of the airflow channel, and achieve product compactness and low-cost manufacturing. Utility Model Content

[0005] Therefore, it is necessary to provide a breathing trainer that addresses the technical problems of cumbersome and inefficient production and assembly processes in existing breathing trainers.

[0006] A breathing trainer includes a main body shell formed by fastening a first shell and a second shell together. Based on this, a main airway and three branch airways are formed inside the main body shell. One end of the main airway is connected to the outside of the main body shell. The other end of the main airway is connected to the top of the three branch airways respectively. The bottom of each branch airway is connected to the atmospheric environment outside the main body shell.

[0007] The first housing is provided with a first air guide cavity, a second air guide cavity, a third air guide cavity, and a fourth air guide cavity; the first air guide cavity is located on one side edge of the first housing; the second air guide cavity, the first air guide cavity, and the fourth air guide cavity are arranged parallel to each other on the adjacent side of the first air guide cavity, and the second air guide cavity, the first air guide cavity, and the fourth air guide cavity are arranged sequentially along a predetermined direction; wherein, the first air guide cavity is configured as an L-shaped cavity formed by connecting a main cavity and a branch cavity, the main cavity is arranged parallel to the adjacent second air guide cavity, and the branch cavity extends from the top of the main cavity. The bending and extending arrangement is located at the top of the second, third, and fourth air guide chambers, and the branch chambers are sequentially connected to the main chamber, the second air guide chamber, the third air guide chamber, and the fourth air guide chamber; the second shell is mirror-image of the first shell and has another set of first, second, third, and fourth air guide chambers arranged in the same manner. Based on this, when the first shell and the second shell are fastened together, the two first air guide chambers form the main air channel, and the two second, two third, and two fourth air guide chambers respectively form three air channels.

[0008] In one embodiment, the second housing is further provided with a connecting pipe. The bottom end of the connecting pipe is located on the outer surface of the side wall of the second housing, and one end of the connecting pipe is connected to the inside of the main cavity, while the other end of the connecting pipe extends a predetermined distance toward the outside of the second housing, thereby forming a pipe connection structure.

[0009] In one embodiment, the connecting pipe is provided with an intercepting net, which is disposed inside the connecting pipe.

[0010] In one embodiment, each of the second, third, and fourth air guide chambers is provided with a first connecting channel and a second connecting channel. The first connecting channel is located at the top of the second, third, and fourth air guide chambers to connect the three air channels with the diversion chamber. The second connecting channel is located at the bottom of the second, third, and fourth air guide chambers to connect the three air channels with the external atmosphere.

[0011] In one embodiment, each of the second, third, and fourth air guide chambers is provided with a limiting protrusion, which is located adjacent to the wall surface on the top side of the corresponding second connecting channel.

[0012] In one embodiment, the top and bottom ends of the first housing are provided with support structures, and the top and bottom ends of the second housing are provided with mirror support structures corresponding to the first housing, so that the first housing and the second housing can be fastened together to form a stable support platform.

[0013] In one embodiment, the first housing is further provided with a sealing structure, which is located at the mating surface where the first housing and the second housing cooperate.

[0014] In one embodiment, the sealing structure described above uses a sealing strip made of an elastic material.

[0015] The aforementioned breathing trainer integrates a complex airway system, which traditionally requires multiple independent parts, into two main injection-molded components by precisely machining the first, second, third, and fourth air-guiding chambers on the first and second shells respectively. The L-shaped main chamber and branch chamber design connect the vertical branch airways with the horizontal convergence airways, allowing the airflow channels to be arranged neatly in three-dimensional space, avoiding unnecessary bends and wasted space, thus achieving a "compact" and "organized" overall structure. The "interlocking" assembly method greatly simplifies the production assembly process, reduces assembly costs and error rates, and improves production consistency. The mirror-symmetric chamber design ensures that when the two shells are interlocked, each pair of corresponding chambers can connect to form a complete and closed airway. Compared with multi-part assembly structures, it has higher integration and structural strength, and can better withstand the impacts and stresses of daily use, improving the product's durability.

[0023] Please see Figures 1 to 4This utility model discloses a breathing trainer 1, which includes a main body shell formed by the interlocking of a first shell 10 and a second shell 20. Based on this, a main airway a and three branch airways b for accommodating an indicator piston or indicator ball are formed inside the main body shell. One end of the main airway a is connected to the outside of the main body shell to connect to the user's breathing end structure such as an external hose, mouthpiece or mask. The other end of the main airway a is connected to the top of the three branch airways b respectively. The bottom end of each branch airway b is connected to the atmospheric environment outside the main body shell, thus constituting the basic structure of the breathing trainer 1. Specifically, the first housing 10 is provided with a first air guide cavity a1, a second air guide cavity b1, a third air guide cavity b2, and a fourth air guide cavity b3; the first air guide cavity a1 is located on one side edge of the first housing 10; the second air guide cavity b1, the first air guide cavity a1, and the fourth air guide cavity b3 are arranged parallel to each other on the adjacent side of the first air guide cavity a1, and the second air guide cavity b1, the first air guide cavity a1, and the fourth air guide cavity b3 are arranged sequentially along a predetermined direction; wherein, the first air guide cavity a1 is configured as an L-shaped cavity formed by connecting a main cavity a11 and a branch cavity a12, the main cavity a11 is arranged parallel to the adjacent second air guide cavity b1, and the branch cavity a12 extends from the top of the main cavity a11 and is arranged in the second air guide cavity b1. 1. The top ends of the third air guide cavity b2 and the fourth air guide cavity b3, and the branch cavity a12 are sequentially connected to the main cavity a11, the second air guide cavity b1, the third air guide cavity b2 and the fourth air guide cavity b3, thereby forming a compact and regular air guide structure; similarly, the second housing 20 is mirror-image of the first housing 10 and is provided with another set of first air guide cavities a1, second air guide cavities b1, third air guide cavities b2 and fourth air guide cavities b3 arranged in the same manner. Based on this, when the first housing 10 and the second housing 20 are fastened together, the two first air guide cavities a1 constitute the main air channel a, and the two second air guide cavities b1, the two third air guide cavities b2 and the two fourth air guide cavities b3 respectively constitute three air channels b, thereby forming a compact and regular complete air guide channel.Based on the above configuration, the breathing trainer 1 of this solution precisely machines the first, second, third, and fourth air-guiding cavities on the first housing 10 and the second housing 20, respectively. This integrates the complex airway system, which traditionally requires multiple independent parts for assembly, onto two main injection-molded parts. The L-shaped main cavity a11 and the branch cavity a12 design can connect the vertical branch airway b with the horizontal converging airway, making the airflow channels neatly arranged in three-dimensional space, avoiding unnecessary bending and space waste, thus achieving a "compact" and "organized" overall structure. The "interlocking" assembly method greatly simplifies the production assembly process, reduces assembly costs and error rates, and improves production consistency. The mirror-symmetric cavity design allows each pair of corresponding cavities to connect and form a complete and closed airway when the two housings are interlocked. Compared with multi-part assembly structures, this design has higher integrity and structural strength, and can better withstand bumps and stresses during daily use, thus improving the product's durability.

[0024] Furthermore, the second housing 20 is also provided with a connecting pipe 21. The connecting pipe 21 is located on the outer surface of the side wall of the second housing 20 at the bottom end corresponding to the main cavity a11. One end of the connecting pipe 21 is connected to the inside of the main cavity a11, and the other end of the connecting pipe 21 extends a predetermined distance toward the outside of the second housing 20, thereby forming a pipe connection structure to achieve effective connection between the main cavity a11 and external hoses, mouthpieces, or masks and other user breathing end structures.

[0025] Specifically, in one embodiment, the connecting pipe 21 is provided with an intercepting net 22, which is disposed inside the connecting pipe 21, so as to intercept large particles of foreign objects and prevent external foreign objects from entering the main cavity a11.

[0026] Furthermore, each of the second air guide chambers b1, the third air guide chamber b2, and the fourth air guide chamber b3 is provided with a first connecting channel c and a second connecting channel d; wherein, the first connecting channel c is respectively located at the top of the second air guide chamber b1, the third air guide chamber b2, and the fourth air guide chamber b3, thereby realizing the connection between the three air channels b and the diversion chamber a12; the second connecting channel d is respectively located at the bottom of the second air guide chamber b1, the third air guide chamber b2, and the fourth air guide chamber b3, thereby realizing the connection between the three air channels b and the external atmosphere.

[0027] Furthermore, each of the second air guide chambers b1, the third air guide chamber b2, and the fourth air guide chamber b3 is provided with a limiting protrusion b101. The limiting protrusion b101 is located adjacent to the wall surface on the top side of the corresponding second connecting channel d to limit the indicator ball contained in each branch airway b, so as to prevent the indicator ball from falling completely to the bottom of the branch airway b and causing adverse effects on the airflow of the second connecting channel d.

[0028] Furthermore, the first housing 10 is provided with support structures 101 at both the top and bottom ends. Correspondingly, the second housing 20 is provided with mirror support structures 101 at both the top and bottom ends corresponding to the first housing 10, so that the first housing 10 and the second housing 20 can be fastened together to form a stable support platform, so as to achieve stable placement of the breathing trainer 1 in both directions.

[0029] Furthermore, the first housing 10 is also provided with a sealing structure 11, which is located at the mating surface of the first housing 10 and the second housing 20, thereby strengthening the spacing and sealing between the main airway a and the three branch airways b, and preventing leakage and crossflow between the airways.

[0030] Specifically, in one embodiment, the sealing structure 11 is a sealing strip made of elastic material, so that when the first housing 10 and the second housing 20 are fastened together, the sealing structure 11 undergoes elastic deformation to fill the splicing gap between the first housing 10 and the second housing 20, thereby ensuring sealing performance.

[0031] In summary, the breathing trainer disclosed in this utility model integrates a complex airway system, which traditionally requires multiple independent parts for assembly, into two main injection-molded parts by precisely machining first, second, third, and fourth air-guiding cavities on the first and second shells respectively. The L-shaped main cavity and branch cavity design connect the vertical branch airways with the horizontal convergence airways, making the airflow channels neatly arranged in three-dimensional space, avoiding unnecessary bending and space waste, thus achieving a "compact" and "organized" overall structure. The "interlocking" assembly method greatly simplifies the production assembly process, reduces assembly costs and error rates, and improves production consistency. The mirror-symmetric cavity design allows each pair of corresponding cavities to connect and form a complete and closed airway when the two shells are interlocked. Compared with multi-part assembly structures, it has higher integration and structural strength, and can better withstand the impacts and stresses of daily use, thus improving the product's durability.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
