Description

Technical Field

[0001] This utility model relates to the field of breathing training technology. Background Technology

[0002] Breathing training is an important means of improving respiratory system function and efficiency, and it is widely used in respiratory disease rehabilitation, physical fitness enhancement, and daily health maintenance. Currently, most common breathing training devices on the market, such as "breathing dumbbells," are unidirectional training structures. Their core principle is that the user blows air into the device, which drives the internal counterweight components (such as small balls or pistons) to move and generate resistance, thereby achieving the purpose of exercising the expiratory muscles.

[0003] However, such one-way cardiopulmonary rehabilitation devices have obvious limitations: First, they are single-function devices that can only train the expiratory muscles and cannot effectively train the inspiratory muscles. The strength and endurance of the inspiratory muscles are equally important for overall respiratory function, resulting in an incomplete training effect. Second, the internal counterweight components (such as built-in weights) of some cardiopulmonary rehabilitation devices are mostly fixed or require disassembly of the main body of the device to remove them. Disassembly is difficult, which not only makes it inconvenient to adjust the training resistance intensity according to the user's needs, but also brings great inconvenience to the cleaning and maintenance of the device. Internal dirt accumulation can easily affect the hygiene of use and the life of the device.

[0004] Therefore, there is room for improvement in existing breathing training equipment. Utility Model Content

[0005] The technical problem solved by this disclosure is to provide a device for bidirectional breathing training.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a cardiopulmonary rehabilitation device, which includes a base shell, a bent tube, a breathing tube, and at least one weight ball; the bent tube is installed on the base shell, and its proximal end is connected to one end of the breathing tube, while the other end of the breathing tube is exposed for the user to blow and exhale; the weight ball is movably placed inside the bent tube, and can move from the proximal end to the distal end of the bent tube when the user blows through the breathing tube, and move from the distal end to the proximal end of the bent tube when the user inhales; a cap is provided at the distal end of the bent tube, and the cap has an air hole for airflow to drive the movement of the weight ball.

[0007] As described above in the cardiopulmonary rehabilitation device, the cap is removable to allow the weight ball to be placed or removed via the distal end of the bent tube.

[0008] As described above, the cardiopulmonary rehabilitation device has a base shell assembled from two half-shells, with the joint of the two half-shells forming a nesting groove, and the proximal and distal ends of the bent tube nested in the nesting groove respectively.

[0009] As described above in the cardiopulmonary rehabilitation device, the bent tube has an overall transparent structure so that the user can observe the movement dynamics of the weight ball.

[0010] As described above, in the cardiopulmonary rehabilitation device, the portion of the bent tube exposed outside the base housing has a transparent observation window along its length, which is used by the user to observe the movement dynamics of the weight ball.

[0011] As described above, the cardiopulmonary rehabilitation device has a cylindrical base housing with two opposing slots on its sidewall. The portion of the bent tube between its proximal and distal ends extends out of the base housing through the corresponding slots. Both the proximal and distal ends of the bent tube are provided with radial flanges, which abut against the inside of the slots to prevent the bent tube from detaching from the base housing.

[0012] As described above in the cardiopulmonary rehabilitation device, the distal end of the bent tube is exposed through the upper surface of the base housing, and the cap is closed and connected to the upper surface of the base housing.

[0013] As described above, the cardiopulmonary rehabilitation device has an anti-slip pad at the bottom of the base housing.

[0014] As described above, the cardiopulmonary rehabilitation device includes an inner tube, a middle tube, and a mouthpiece; one end of the inner tube is connected to the proximal end of the bent tube, the end of the inner tube away from the bent tube is connected to one end of the middle tube, and the mouthpiece is connected to the end of the middle tube away from the inner tube.

[0015] As described above in the cardiopulmonary rehabilitation device, the bent tube is a U-shaped tube.

[0016] The beneficial effects of this disclosure are as follows: By combining the bent tube with the weight ball, the user can blow air through the breathing tube to blow the weight ball from the proximal end to the distal end (training the expiratory muscles), and inhale while exhaling to pull the weight ball back from the distal end to the proximal end (training the inspiratory muscles). This breaks through the limitation of existing unidirectional breathing dumbbells that can only train the expiratory muscles, and realizes the synchronous training of the inspiratory and expiratory muscles, significantly improving the integrity and effectiveness of breathing training.

[0027] See appendix Figure 1-3The image shows a cardiopulmonary rehabilitation device 1, which includes a base housing 2, a bent tube 3, a breathing tube 4, and at least one weight ball 5. The bent tube 3 is mounted on the base housing 2, with its proximal end 30 connected to one end of the breathing tube 4, and the other end of the breathing tube 4 exposed for the user to exhale. The weight ball 5 is movably placed inside the bent tube 3 and can move from the proximal end 30 to the distal end 31 of the bent tube 3 when the user exhales through the breathing tube 4, and from the distal end 31 to the proximal end 30 when the user inhales. A cap 21 is provided at the port 32 of the distal end 31 of the bent tube 3, and the cap 21 has an air hole 22 for airflow to drive the movement of the weight ball 5.

[0028] In this embodiment, the core structure of the cardiopulmonary rehabilitation device 1 includes a base shell 2, a bent tube 3, a breathing tube 4, weight balls 5, and a cover 21. The base shell 2 is the basic structural carrier of the cardiopulmonary rehabilitation device 1, and the remaining structures are assembled and connected through the base shell 2. The cardiopulmonary rehabilitation device 1 is placed and held by the user through the base shell 2. The bent tube 3 is preferably in the form of a U-shaped tube (shown as a transparent U-shaped tube in the figure), serving as an airflow channel and a moving carrier for the weight balls 5. It is fixed by the base shell 2. The breathing tube 4 is the airflow interaction medium between the user and the cardiopulmonary rehabilitation device 1. The cover 21 realizes the dual functions of limiting the weight balls 5 and allowing airflow.

[0029] Using the breathing tube 4 as a reference, the end of the bend tube 3 connected to the breathing tube 4 is defined as the proximal end 30, and the end away from the breathing tube 4 is defined as the distal end 31. When the user blows air through the breathing tube 4, the airflow enters the proximal end 30 of the bend tube 3 through the breathing tube 4, flows along the inside of the bend tube 3 towards its distal end 31, and exits through the air vent 22. Under the action of the airflow, the weight ball 5 moves from the proximal end 30 to the distal end 31 of the bend tube 3. When the user inhales air through the breathing tube 4, the airflow enters the distal end 31 of the bend tube 3 through the air vent 22, flows along the inside of the bend tube 3 towards its proximal end 30, and is inhaled by the user. Under the action of the airflow, the weight ball 5 moves from the distal end 31 to its proximal end 30 of the bend tube 3. Thus, the user achieves bidirectional breathing training.

[0030] In some embodiments, the cap 21 is removable to allow the weight ball 5 to be placed or removed via the distal end 31 port 32 of the bent tube 3.

[0031] This embodiment makes further improvements by optimizing the connection between the distal end 31 (port 32) of the bent tube 3 and the cap 21. This ensures that the cap 21 can be easily disassembled while still meeting the functional requirements for placing and removing the weight balls 5. The port 32 of the bent tube 3 serves as the channel for placing and removing the weight balls 5. There are usually multiple weight balls 5 of varying weights, allowing users to freely choose the appropriate number and weight of weight balls 5 to place inside the bent tube 3, which helps in conducting scientific breathing training. Furthermore, the cap 21 is removable, facilitating cleaning and maintenance of the bent tube 3 and the weight balls 5.

[0032] In some embodiments, the base housing 2 is assembled from two half-shells 20, and the joint of the two half-shells 20 forms a nesting groove 24, in which the proximal end 30 and distal end 31 of the bent tube 3 are nested respectively within the nesting groove 24.

[0033] The base shell 2 adopts a symmetrical assembly design of two half-shells 20. The nesting groove 24 consists of two parts, which are respectively formed on the two half-shells 20. After the two half-shells 20 are assembled, they together form the nesting groove 24 at the splice, which is used to fix the proximal end 30 and the distal end 31 of the bent tube 3. The middle part of the bent tube 3 is exposed outside the base shell 2. During assembly, the proximal end 30 and the distal end 31 of the bent tube 3 can be placed into the nesting groove 24 of one half-shell 20, and then the other half-shell 20 is assembled with it. The two half-shells 20 fit tightly together, and the nesting groove 24 is completely closed, wrapping and fixing the proximal end 30 and the distal end 31 of the bent tube 3.

[0034] The two half-shells 20 can be fixed together by screwing. A small hole is provided on one half-shell 20, and a screw hole is provided on the other half-shell 20 to mate with the screw thread. The small hole and the screw hole are positioned correspondingly. The screw is inserted through the small hole and tightened into the screw hole, thereby fixing the two half-shells 20 together. Rubber plugs can be placed at the small holes on the half-shells 20 to protect the connection and improve the appearance of the shell.

[0035] In some embodiments, the bent tube 3 is an entirely transparent structure, allowing the user to observe the movement of the weight ball 5. To achieve the core functions of overall transparency and observation of the weight ball 5's movement, the bent tube 3 can be integrally molded from high-transmittance medical-grade acrylic material. The entirely transparent U-shaped bent tube 3 is installed into the nested slots 24 of the two half-shells 20. After assembly and fixation, the arc-shaped section in the middle of the bent tube 3 is almost completely exposed, forming an unobstructed observation area. Furthermore, scale lines can be printed along the length of the bent tube 3, allowing the user to quantify breathing intensity and make training more targeted. At the same time, the transparent tube body allows the user to directly observe the internal cleanliness and perform timely cleaning and maintenance. Weight balls 5 of different weights can be of different colors, further improving visual recognition and making it easier for users to select different weight weights of weight balls 5 for use. It also allows for quick detection of the weight ball 5's movement, enabling adjustments to breathing training movements.

[0036] In some embodiments, the portion of the bent tube 3 exposed outside the base housing 2 has a transparent observation window along its length, which is used by the user to observe the movement dynamics of the weight ball 5.

[0037] A continuous transparent observation window is provided along the length of the bent tube 3 exposed in the base housing 2 (extending from the exposed portion at the proximal end 30 to the exposed portion at the distal end 31), covering the entire path of the weight ball 5's movement. The transparent observation window is made of transparent material and is integrated with the main body of the bent tube 3 to ensure clear observation and structural integrity. The transparent observation window can be made of high-transmittance PC plastic, and the tube body can be made of ABS, using a secondary injection molding process to integrally mold the two, with a sealed joint to ensure a smooth inner wall and good airtightness of the tube. Similarly, graduations can be set along the transparent observation window, allowing users to quantitatively observe the degree of breathing training.

[0038] In this embodiment, the transparent observation window is set along the exposed part of the bent tube 3, reducing the amount of high-cost transparent material used and lowering the overall manufacturing cost, while maintaining the core observation function. The non-transparent tube body also enhances the structural strength of the bent tube 3. The observation window precisely covers the movement path of the weight ball 5, avoiding dust adhesion caused by the transparent design in unrelated areas (reducing cleaning frequency), thus balancing applicability and cost-effectiveness.

[0039] In some embodiments, the base housing 2 is cylindrical, and two opposing slots 25 are formed on the side wall of the base housing 2. The portion between the proximal end 30 and the distal end 31 of the bent tube 3 extends out of the corresponding slots 25 and is exposed outside the base housing 2. Both the proximal end 30 and the distal end 31 of the bent tube 3 are provided with radial flanges 33, which abut against the inner side of the slots 25 to prevent the bent tube 3 from detaching from the base housing 2.

[0040] The base housing 2 adopts a cylindrical structure symmetrically assembled from two half-shells 20. Two opposing slots 25 are located on the side wall of the base housing 2, serving as channels for the passage of the bent tube 3. The two slots 25 are symmetrically distributed radially along the cylinder, corresponding to the proximal end 30 and distal end 31 of the bent tube 3, respectively. Radial flanges 33 are provided on the outer walls of both the proximal end 30 and the distal end 31. When the bent tube 3 is fixed within the nested groove 24, the radial flanges 33 abut against the inner side of the corresponding slot 25, forming a stop and stabilizing the assembly of the bent tube 3 and the base housing 2.

[0041] In some embodiments, the port 32 of the distal end 31 of the bent tube 3 is exposed through the upper surface of the base housing 2, and the cap 21 is connected to the upper surface of the base housing 2. The cap 21 can be fitted to the upper surface of the base housing 2 by means of tight fit, snap-fit, or threaded connection. When the cap 21 is connected to the base housing 2, it covers the port 32 to prevent the weight ball 5 from falling off. After the cap 21 is opened, the port 32 is exposed, making it easy to put in and take out the weight ball 5.

[0042] In some embodiments, an anti-slip pad 23 is disposed on the bottom of the base housing 2. The anti-slip pad 23 can be made of soft rubber and can be laid on the bottom of the base housing 2 by means of nesting or bonding, so as to play a protective role in preventing slipping and wear.

[0043] In some embodiments, the breathing tube 4 includes an inner tube 40, a central flexible tube 41, and a mouthpiece 42; one end of the inner tube 40 is connected to the proximal end 30 of the bent tube 3, the end of the inner tube 40 away from the bent tube 3 is connected to one end of the central flexible tube 41, and the mouthpiece 42 is connected to the end of the central flexible tube 41 away from the inner tube 40.

[0044] The inner tube 40, as the rigid connection part of the breathing tube 4, mainly achieves stable docking with the bent tube 3. It can be connected using methods such as tight insertion or threaded connection. The aperture at the connection point with the proximal end 30 of the inner tube 40 is smaller than the diameter of the weight ball 5, ensuring airflow while preventing the weight ball 5 from flowing into the inner tube 40 from the connection point. The base housing 2 has a through hole 26, through which the end of the inner tube 40 furthest from the bent tube 3 connects to the central flexible tube 41. The central flexible tube 41 provides angle adjustment for the breathing tube 4, adapting to different user postures. It can be made of food-grade silicone material, possessing good flexibility and resilience. The central flexible tube 41 can be tightly connected to the inner tube 40 and the mouthpiece 42 using a tight insertion method. The mouthpiece 42 directly contacts the user's mouth, with a focus on comfort and hygiene. It can be made of medical-grade PP plastic with an antibacterial surface treatment, a seamless structure for easy wiping and disinfection, and can be disassembled and replaced independently.

[0045] This cardiopulmonary rehabilitation device 1 uses bidirectional breathing to drive the movement of weighted balls 5 as its core function. Its basic structure includes a base shell 2, a bent tube 3, a breathing tube 4, at least one weighted ball 5, and a cap 21. It enables bidirectional breathing training without adjustment or flipping. As the user exhales and inhales, airflow enters the bent tube 3 through the breathing tube 4, driving the weighted ball 5 to move back and forth within the tube. The air vents 22 of the cap 21 ensure airflow for this process. The design also incorporates several practical optimizations: the base uses a modular structure and nested design to secure the bent tube 3; the cap 21 is detachable, allowing users to freely select the number and weight of the weighted balls 5 to adjust the intensity; the bent tube 3 has a transparent structure for observing its movement; the breathing tube 4 features a three-section flexible design to improve adaptability; and the base has an anti-slip structure to enhance stability.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. For those skilled in the art, this utility model can have various modifications, combinations, and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of the claims of this utility model.
