Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and more specifically, to a pulmonary function rehabilitation device for respiratory nursing. Background Technology

[0002] In respiratory nursing, pulmonary rehabilitation is crucial for patients with respiratory diseases such as chronic obstructive pulmonary disease (COPD), asthma, and pulmonary fibrosis. Effective pulmonary rehabilitation can improve patients' respiratory function, enhance their quality of life, and reduce the frequency and severity of disease attacks. Currently, common pulmonary rehabilitation methods include breathing exercises and exercise training. Breathing exercises often utilize simple breathing machines, requiring patients to perform specific breathing movements to strengthen their respiratory muscles; exercise training encompasses various forms such as aerobic exercise and strength training. However, existing rehabilitation methods lack precise, personalized guidance during implementation, making it difficult to dynamically adjust rehabilitation plans based on the patient's real-time pulmonary function status, resulting in inconsistent rehabilitation outcomes.

[0003] While existing pulmonary rehabilitation devices can detect a patient's lung capacity to some extent, they often only record the data. After determining a patient's lung capacity, they cannot tailor a highly targeted and scientifically effective exercise plan based on the results, or the provided plan lacks flexibility and adaptability, failing to adjust the intensity and method of exercise as the patient's lung function improves. This makes it difficult for patients to receive effective exercise guidance after lung capacity testing, resulting in slow pulmonary rehabilitation and unsatisfactory overall exercise outcomes.

[0004] Therefore, we have made improvements to this and proposed a pulmonary function rehabilitation device for respiratory nursing. Utility Model Content

[0005] In order to achieve the above-mentioned objectives, this utility model provides a pulmonary function rehabilitation device for respiratory nursing to improve the above-mentioned problems.

[0006] The application is as follows:

[0007] include:

[0008] The box body has at least three independent upright cavities, and at least two of the upright cavities have a convex cross-section, and also has:

[0009] A wrapping plate is placed on the bottom surface of the vertical cavity and divides the vertical cavity into chambers that are wider at the top and narrower at the bottom;

[0010] The cavity is formed by a wrapping plate surrounding the vertical cavity, and its cross-section is smaller than that of the vertical cavity.

[0011] A connecting cavity is provided on the box body, connecting each of the upright cavities;

[0012] A ventilation slot is provided on the side of the box body away from the ground and connects to the vertical cavity;

[0013] A sphere, positioned within an upright cavity;

[0014] A convex sphere, mounted on the wrapping plate, extends in the same convex shape as the convex upright cavity, and has the following characteristics:

[0015] An extension portion is provided on the convex sphere;

[0016] The trachea is located on the box body and connects to the upright cavity;

[0017] When the gas lifts the sphere through the upright cavity until it contacts the convex sphere, the extension extends in the direction of covering the ventilation channel.

[0018] Preferably, the convex sphere further includes:

[0019] The recess is formed on the surface adjacent to the convex sphere and the sphere, and is located on the path of movement of the sphere.

[0020] Preferably, the diameter of the sphere is smaller than that of the cavity, and the diameter of the convex sphere is larger than that of the cavity but smaller than that of the vertical cavity.

[0021] Preferably, the extension portion is an annular strip made of elastic material, and a counterweight ring is embedded at its root.

[0022] Preferably, the communicating cavity is provided with a valve to control the communication state between it and the upright cavity.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] In the scheme of this application:

[0025] To address the issues of abrupt resistance adjustment and limited training intensity modes in existing pulmonary function rehabilitation training technologies, this application utilizes a convex sphere-sphere contact linkage mechanism to achieve dynamically increasing airflow resistance training. When the airflow lifts the sphere and precisely embeds it into the convex sphere's depression, the diverted airflow pushes the convex sphere downwards. Its elastic extension section, embedded with a counterweight ring, accelerates the coverage of the ventilation slot, causing the expiratory resistance to increase steadily with increasing force, thus strengthening respiratory muscle training. Simultaneously, the convex matching structure guides the components to move along a set path, effectively avoiding rigid impacts through airflow dispersion buffering and contact surface friction, extending the equipment's lifespan. The connecting chamber valve independently controls the opening and closing of multiple chambers, supporting flexible graded and combined training modes to adapt to the needs of different rehabilitation stages.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0032] For an example, please refer to... Figure 1 , Figure 2 and Figure 3 A pulmonary function rehabilitation device for respiratory nursing, comprising:

[0033] The box 1 has at least three independent upright cavities 11, of which at least two upright cavities 11 have convex cross-sections, and also has:

[0034] A wrapping plate 12 is disposed on the bottom surface of the vertical cavity 11 and divides the vertical cavity 11 into a chamber that is wider at the top and narrower at the bottom;

[0035] The cavity 13 is formed by the enclosure plate 12 surrounding the vertical cavity 11, and its cross-section is smaller than that of the vertical cavity 11.

[0036] A connecting cavity 14 is provided on the box body 1 and connects to each upright cavity 11;

[0037] Ventilation slot 15 is provided on the side of box 1 away from the ground and is connected to vertical cavity 11;

[0038] Sphere 2 is disposed in vertical cavity 11;

[0039] The convex sphere 3, mounted on the wrapping plate 12, extends in the same convex shape as the convex upright cavity 11, and has the following characteristics:

[0040] Extension portion 32 is provided on convex sphere 3;

[0041] Trachea 4 is installed on box 1 and connects to vertical cavity 11;

[0042] When the gas passes through the upright cavity 11 and lifts the sphere 2 to contact the convex sphere 3, the extension portion 32 extends in the direction of covering the ventilation channel.

[0043] When a patient blows air through the trachea 4, the airflow is distributed to the bottom of each individual upright cavity 11 via the connecting cavity 14. This rising airflow acts on the sphere 2 at the bottom of the cavity, generating an upward lifting force. As the patient's blowing force increases, the sphere 2 rises steadily against gravity within the cavity formed by the covering plate 12. Crucially, when the blowing force reaches a certain threshold, the sphere 2 is lifted to make physical contact with the convex sphere 3 mounted on the covering plate 12.

[0044] When the sphere 2 comes into contact with the depression 31, because the sphere 2 is smaller than the convex sphere 3, the airflow, when passing the junction of the sphere 2 and the convex sphere 3, partially lifts the convex sphere 3. Under the impact force of the sphere 2, the direct force of the airflow, and gravity, the extension part 32 extends, thereby blocking the upright cavity 11. This gradually blocks the passage from the trachea 4, the connecting cavity 14, the ventilation channel 15 to the atmosphere, making the blowing process increasingly difficult. This results in a gradual change in the airflow, allowing the patient to receive stable exercise during use.

[0045] Furthermore, since the cross-section of the convex ball 3 is of different sizes, and the vertical cavity 11 has the same shape as the convex ball 3, the convex ball 3 can only move along the same path. However, the airflow is more likely to come out from the smaller part of the convex ball 3. If the airflow is too strong, the convex ball 3 will flip over with the larger part, causing the ball 2 and the smaller part of the convex ball 3 to come into contact with the vertical cavity 11, generating friction. This prevents the ball 2 and the convex ball 3 from colliding and extends the service life of the equipment.

[0046] The convex sphere 3 also includes:

[0047] The recess 31 is formed on the surface adjacent to the convex sphere 3 and the sphere 2, and is located on the movement path of the sphere 2;

[0048] When the airflow lifts the sphere 2 to the top of the vertical cavity 11, the sphere 2 is precisely embedded in the recess 31 of the convex sphere 3, ensuring stable and centered contact.

[0049] The diameter of sphere 2 is smaller than that of cavity 13, and the diameter of convex sphere 3 is larger than that of cavity 13 but smaller than that of vertical cavity 11.

[0050] The extension 32 is a ring-shaped strip made of elastic material, and a counterweight ring is embedded at its root;

[0051] After the sphere 2 comes into contact with the convex sphere 3, it pushes the sphere downward; the counterweight ring embedded in the root of the extension 32 uses gravity to accelerate the downward pressure of the elastic ring strip, quickly covering the ventilation groove 15.

[0052] A valve is provided in the connecting cavity 14 to control the communication state between it and the upright cavity 11;

[0053] The valves in the connecting cavity 14 can independently open and close each upright cavity 11, enabling single-cavity graded training or multi-cavity combined training to meet the needs of different rehabilitation stages.

[0054] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
