Description

Technical Field

[0001] This utility model belongs to the field of cardiology nursing technology, and specifically relates to a respiratory training aid for cardiac rehabilitation. Background Technology

[0002] Cardiac rehabilitation is a crucial component of comprehensive cardiovascular disease management, playing a vital role in improving patients' cardiac function, enhancing their quality of life, and reducing the risk of recurrent cardiovascular events. Breathing training is a core element of cardiac rehabilitation; proper breathing exercises can regulate the balance of the autonomic nervous system, improve cardiopulmonary coordination, and reduce cardiac workload. Cardiac rehabilitation breathing training aids have emerged as tools to assist patients in effective breathing training. They aim to guide patients in mastering correct breathing rhythm, depth, and breath-holding techniques to achieve optimal rehabilitation results.

[0003] Chinese utility model patent publication number: CN220554569U (application number: CN202322153542.X): An assisted cardiac magnetic resonance breathing trainer, comprising a main body device for wearing on the face for inhalation, exhalation, and breath-holding, and a display device on the main body device for displaying the effects of inhalation, exhalation, and breath-holding. One side of the display device has an air inlet / outlet device for unidirectional air intake and exhaust. The display device includes a display tube made of BB1 glass, with two symmetrically arranged support rods inside the display tube, and a wire connecting the support rods. This utility model's assisted cardiac magnetic resonance breathing trainer, through its floating and stationary settings, makes the examiner's inhalation, exhalation, and breath-holding states more clearly; through its unidirectional air intake setting, it avoids external air entering the device and interfering with training; and through its unidirectional air intake and unidirectional air exhaust setting, it ensures that hypoxia will not occur during prolonged breathing training.

[0004] First, the display tube in the aforementioned breathing trainer is made of BB1 glass. While it offers some transparency and stability, glass is heavy and fragile. In everyday cardiac rehabilitation training scenarios, patients may accidentally bump into it or drop it, damaging the display tube. This not only increases the cost of equipment repair or replacement but also poses a potential safety hazard. Second, the trainer's support rods consist of two symmetrically arranged straight rods. This structure offers limited stability when providing internal support, especially when the patient's breathing is rapid or irregular. The movement of the ribbons on the threads may be affected by the limitations of the support structure, resulting in inaccurate and unstable display of breathing status. Furthermore, the ribbon design is relatively simple, and its movement may not attract sufficient attention from the patient, hindering their ability to visually assess subtle changes in breathing. Additionally, during prolonged use, the rigidity of the connecting tube in the main unit may cause discomfort due to pressure on the patient's face, and the ear loop fixation method may be unstable and uncomfortable. For cardiac rehabilitation patients requiring long-term breathing training, this could reduce adherence to the device. Utility Model Content

[0005] In view of this, the present invention provides a respiratory training aid for cardiac rehabilitation, which solves the safety hazards of traditional respiratory training devices and optimizes the auxiliary effect of respiratory training for cardiac rehabilitation.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a respiratory training aid for cardiac rehabilitation, including a breathing mask assembly. The breathing mask assembly has a visual display component for displaying the effects of inhalation, exhalation, and breath-holding. A gas inlet / outlet component for unidirectional air intake and exhaust is located on one side of the visual display component. The visual display component includes a display tube with three evenly distributed arc-shaped support bars inside. The three arc-shaped support bars are circumferentially distributed at equal angles within the display tube. An elastic rope is arranged between the arc-shaped support bars, and multiple colored spheres are strung on the elastic rope. The gas inlet / outlet component includes an exhaust pipe with a first Tesla valve. An intake pipe with a second Tesla valve is located on one side of the exhaust pipe.

[0008] The technical effects of the breathing training aid for cardiac rehabilitation provided by this utility model are as follows: Specifically, the central angle of each arc-shaped support bar is approximately 120°, and its two ends are fixed to corresponding positions on the inner wall of the visualization display tube. The curvature of the arc-shaped support bar matches the curvature of the inner wall of the visualization display tube, and its installation position is close to the middle area of ​​the visualization display tube. This allows the arc-shaped support bar to provide uniform support force from three directions when the elastic rope and the colored ball move due to the impact of airflow, preventing the elastic rope from shaking excessively or the colored ball from colliding with the inner wall of the visualization display tube due to uneven force. At the same time, the connection points between the arc-shaped support bar and the inner wall of the visualization display tube are evenly distributed in the circumferential direction, ensuring the stability and symmetry of the entire structure. This allows the user to clearly and accurately observe the movement of the colored ball on the elastic rope, thereby intuitively judging the breathing situation. Furthermore, this arrangement also facilitates the uniform distribution of airflow within the visualization display tube, making the movement of the colored ball more accurately reflect various characteristics of breathing, such as the depth, speed, and rhythm of breathing.

[0009] Based on the above technical solution, the respiratory training aid for cardiac rehabilitation of this utility model can be further improved as follows:

[0010] The breathing mask assembly includes a breathing mask body, a connecting hose on the breathing mask body, and headbands on both sides of the connecting hose.

[0011] Furthermore, the exhaust pipe is made of medical-grade silicone, and the exhaust pipe is connected to the display tube and the first Tesla valve respectively through a sealing joint.

[0012] Furthermore, the intake pipe is connected to the second Tesla valve via a sealing joint, and the intake pipe is made of medical-grade silicone.

[0013] Furthermore, the sphere is spherical with a diameter of 3-5cm, has a hollow internal structure, weighs between 5-10g, and is made of environmentally friendly rubber material.

[0014] Environmentally friendly rubber materials refer to natural rubber or synthetic rubber that has undergone environmentally friendly treatment, such as EPDM rubber. Natural rubber has the characteristics of high elasticity and good wear resistance, while EPDM rubber has excellent properties such as weather resistance, ozone resistance, and chemical corrosion resistance. Moreover, it does not contain harmful substances during the production process and meets environmental protection requirements.

[0015] Furthermore, the display tube is connected to the exhaust pipe and the breathing mask assembly respectively via a sealing joint.

[0016] The sealing joint uses a combination of internal and external threads for connection. Corresponding thread structures are set at the corresponding connection parts of the exhaust pipe, intake pipe, visual display tube, and breathing mask assembly. The connection is tightened by rotation. At the same time, a rubber sealing ring is set at the threaded connection to ensure the connection is airtight and prevent gas leakage.

[0017] Furthermore, the arc-shaped support strip is made of nylon, and the arc-shaped support strip is connected to the display tube through a slot.

[0018] Furthermore, the headband is made of breathable fabric and has an adjustable length.

[0019] The headband has Velcro straps at both ends. One end has a longer loop side, while the other end has hooks that can be attached to different positions on the loop side, allowing for length adjustment. The breathable fabric is typically a blend of cotton and polyester fibers. Cotton fibers offer excellent moisture absorption and breathability, absorbing exhaled moisture to keep the skin dry and comfortable; polyester fibers provide strength and abrasion resistance, ensuring the headband's durability.

[0020] Furthermore, the inner wall of the display tube is provided with an annular groove that matches the arc-shaped support strip, and the end of the arc-shaped support strip is provided with a protrusion that matches the groove.

[0021] Furthermore, the display tube is made of transparent acrylic material.

[0022] Compared with the prior art, the beneficial effects of the respiratory training aid for cardiac rehabilitation provided by this utility model are:

[0023] The visualization display tube is made of high-strength transparent acrylic material, which offers significant advantages over traditional BB1 glass. Its weight is greatly reduced, lessening the burden on patients caused by excessive equipment weight, especially for frail cardiac rehabilitation patients, making it easier and more convenient to use. Simultaneously, acrylic material has excellent impact resistance, effectively resisting accidental collisions and drops that may occur during daily use, greatly reducing the risk of display tube breakage and improving the overall safety and durability of the equipment. This not only reduces repair or replacement costs due to equipment damage but also ensures the patient's personal safety during training, allowing them to focus more on breathing exercises without worrying about the adverse consequences of equipment damage.

[0024] The support structure inside the visualization display tube has been changed from two straight rods to three arc-shaped support bars, evenly distributed in a circular pattern. This structural design provides more uniform and stable support. When the patient performs breathing training, airflow enters the visualization display tube through the intake pipe, causing the colored ball on the elastic rope to move. The arc-shaped support bars effectively support the elastic rope and the colored ball from three directions, making the trajectory of the colored ball under the influence of airflow more stable and regular. Patients can observe changes in the amplitude, speed, and direction of the colored ball's movement in multiple dimensions to more accurately judge key information such as their breathing depth, speed, and rhythm. For example, when the breathing depth is greater, the amplitude of the colored ball's movement will increase accordingly; when the breathing speed is faster, the oscillation frequency of the colored ball will also increase. This multi-dimensional and intuitive display of breathing status helps patients better understand their breathing situation, adjust their breathing training strategies in a timely manner, and thus improve the effectiveness of breathing training.

[0025] The design of the colored balls offers significant advantages over traditional ribbons. Made of environmentally friendly rubber, the balls possess a certain weight and elasticity. Their non-slip texture increases friction with the elastic cord, making the balls more securely attached and less prone to slipping or falling off due to airflow. The hollow structure and suitable weight allow the balls to produce a variety of noticeable movements under airflow, such as swinging, rotating, and bouncing. These movements are more eye-catching than the simple swinging of ribbons, better attracting the patient's attention and allowing them to focus on the ball's movements. This, in turn, helps them become more aware of changes in their breathing, improving self-monitoring abilities and training effectiveness during breathing exercises. Attached Figure Description

[0038] Furthermore, in the above technical solution, the display tube 201 is connected to the exhaust pipe 31 and the breathing mask assembly 10 respectively through a sealing joint.

[0039] Furthermore, in the above technical solution, the arc-shaped support strip 21 is made of nylon material, and the arc-shaped support strip 21 is connected to the display tube 201 through a slot.

[0040] Furthermore, in the above technical solution, the headband 11 is made of breathable fabric and has an adjustable length structure.

[0042] Furthermore, in the above technical solution, the display tube 201 is made of transparent acrylic material.

[0043] Specifically, the principle of this utility model is as follows:

[0044] In terms of fluid dynamics principles, when a patient wears a breathing mask and undergoes breathing training, air enters through the intake pipe. A Tesla valve on the intake pipe ensures that air flows into the device in only one direction, preventing backflow. After entering the visualization display tube, the air, due to its flow characteristics, exerts a force on the elastic cord and colored ball inside. According to Bernoulli's principle, the faster the gas flow, the lower the pressure. During inhalation, the airflow is faster, resulting in relatively lower pressure inside the visualization display tube. The colored ball will then move accordingly under the influence of the airflow, such as swinging, rotating, or bouncing in the direction of the airflow. During exhalation, the airflow direction is reversed, the Tesla valve opens, and the gas is expelled. The colored ball then changes its motion again under the combined action of the airflow and the elastic cord. By observing and analyzing the motion of the colored ball, various parameters of the patient's breathing can be indirectly understood.

[0045] Regarding the visualization principle, the visualization display tube is made of transparent material, with colored balls and elastic ropes inside forming the core of the visualization. The positional changes and trajectories of the colored balls on the elastic ropes visually reflect changes in airflow, thus reflecting the patient's respiratory status. The arc-shaped support bar provides a stable spatial framework for the movement of the colored balls, allowing their movement to occur in a relatively stable and regular environment, facilitating patient observation and understanding. Simultaneously, the scale markings on the outer surface of the visualization display tube serve as an auxiliary reference. When the colored balls move to different scale positions, patients can more accurately understand their respiratory depth values, further improving the quantification and accuracy of respiratory training.
