Description

Technical Field

[0001] The present invention relates to the technical field of nasal respiration rehabilitation, and more specifically, the present invention is a nasal respiration training device for the rehabilitation care of chronic obstructive pulmonary disease (COPD). Background Art

[0002] COPD is a chronic inflammatory lung disease that includes two main types: chronic bronchitis and emphysema. As the disease progresses, the patient's airway becomes narrow, and the elasticity of the alveoli decreases, leading to difficulty in breathing. Respiratory training is one of the important means for COPD patients to manage their condition. Through a series of breathing exercises, patients can strengthen the strength of the respiratory muscles, improve lung function, reduce dyspnea, and improve the quality of life. By training the respiratory muscle groups, their functions can be enhanced, achieving the effect of improving the overall physical and mental condition, playing an important role that cannot be replaced by drugs. Respiratory training includes various different methods, such as nasal respiration training, pursed-lip breathing, and abdominal breathing, etc.

[0003] Currently, during the nasal respiration training in the rehabilitation process, due to partial loss of the patient's own breathing ability, when breathing through the nose, it shows rapidity and a too short stroke during the entire breathing cycle, resulting in incomplete inflation and contraction of the patient's lungs, being unable to prompt the expulsion of the remaining air in the lungs, and unable to deeply stimulate the lungs, leading to an unsatisfactory overall training effect. The patient cannot specifically improve the depth of the entire breathing process through nasal respiration and simultaneously stimulate the deep tissues of the lungs. Therefore, there is an urgent need for a device to assist patients in nasal respiration training. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a nasal respiration training device for the rehabilitation care of COPD. By setting a triangular block, a rotating ball, and an arc-shaped notch, when the patient breathes through the nasal cavity, the external air flow will gradually enter the interior of the cavity through the opening of the respirator and drive the rotating ball to start rotating. When the rotating ball rotates, the gap range between the arc-shaped notch and the corner of the triangular block changes continuously from small to large and then from large to small. Thus, when the patient uses nasal respiration, a variable weak resistance is provided, ensuring that the amount of inhaled air is uniform and the stroke is lasting in each breathing cycle, thereby achieving the effect of deep breathing and deeply stimulating the patient's lung tissue, effectively improving the rehabilitation effect of nasal respiration training, so as to solve the problems raised in the above-mentioned background art.

[0005] To achieve the above object, the present invention provides the following technical solution: A nasal breathing training device for the rehabilitation and nursing of chronic obstructive pulmonary disease, comprising a breathing apparatus. The overall structure of the breathing apparatus is a trapezoidal structure with a wider upper part and a narrower lower part. A pair of through pipes are connected and communicated at the bottom end of the breathing apparatus. A rubber gasket is sleeved on the surface of the through pipes. On the left and right sides of the inner wall surface of the breathing apparatus, a pair of triangular blocks are symmetrically installed respectively. The triangular blocks are triangular in shape. The inclination of the inclined surface of one side of the triangular block near the inlet of the breathing apparatus is smaller than the inclination of the inclined surface of the side near the through pipe. Spherical cavities are formed on the inner wall surfaces at the front and rear ends of the breathing apparatus, and a rotating ball is rotatably installed inside the spherical cavities; Arc-shaped notches are formed on the surface of the rotating ball. The number of the arc-shaped notches is two, and the two arc-shaped notches are arranged end to end. The width of the arc-shaped notch gradually increases from one side to the other side as a whole, and the curvature of the outer arc track gradually increases synchronously as a whole. On the upper and lower ends of the surface of the rotating ball, diversion notches are symmetrically formed. The arc-shaped notches and the diversion notches are communicated with each other. The corner of the triangular block near the rotating ball extends into the inner part of the arc-shaped notch on the surface of the rotating ball, and the extension distance is equal to the minimum width value of the arc-shaped notch; A cavity is formed inside the breathing apparatus. The internal space of the cavity is divided by a pair of spherical cavities and forms two trapezoidal regions. The widths of the ends where the two trapezoidal regions are in contact with each other are equal. The width of the other end of the trapezoidal region in the upper half part is greater than the width of the other end of the trapezoidal region in the lower half part, and the length of the trapezoidal range in the upper half part is less than the length of the trapezoidal range in the lower half part. On the inner wall of the breathing apparatus near the through pipes and between the two through pipes, an arc-shaped inner wall is formed. The arching direction of the arc of the arc-shaped inner wall points to the center position of the rotating ball.

[0006] In a preferred embodiment, the diameter of the rubber gasket is greater than the diameter of the through pipe, and the surface of the rubber gasket is provided with a matte texture.

[0007] In a preferred embodiment, a clearance fit is adopted between the spherical cavity and the rotating ball, and a layer of lubricating liquid is applied between them.

[0008] In a preferred embodiment, the length of the arc-shaped notch is adapted to the thickness of the triangular block, and the corners of the triangular block are provided with rounded transitions.

[0009] In a preferred embodiment, the cross-section of the diversion notch is triangular, and the diversion notch is annularly surrounded and opened on the outer side surface of the rotating ball.

[0010] The technical effects and advantages of the present invention: By providing a triangular block, a rotating ball, and an arc-shaped notch, and through their mutual cooperation, when a patient breathes through the nasal cavity, the external air flow will gradually enter the interior of the cavity through the opening of the respirator. Under the guidance of the cavity, it will gradually penetrate towards one side of the rotating ball, pass through the gap reserved between the rotating ball and the triangular block, and drive the rotating ball to start rotating through the frictional force generated when the air flow contacts the rotating ball. When the rotating ball rotates, due to the design of the increasing volume of the arc-shaped notch on its side surface, the gap range between the arc-shaped notch and the corner of the triangular block continuously changes from small to large and then from large to small. Therefore, when the patient breathes through the nasal cavity, a variable weak resistance is provided, thus preventing the patient from inhaling a large amount of air in a short period of time, which may cause the entire breathing cycle to be too rapid and the travel distance to be too short, unable to deeply stimulate the lungs. This ensures that the amount of air inhaled by the patient in each breathing cycle is uniform and the travel distance is long and slow, thereby achieving deep breathing and deeply stimulating the patient's lung tissue, effectively improving the rehabilitation effect of the patient's nasal breathing training.

[0013] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0014] As shown in the attached Figure 1 to the attached Figure 18 A nasal breathing training device for the rehabilitation and nursing of patients with chronic obstructive pulmonary disease, including a respirator 1. The overall structure of the respirator 1 is in a trapezoidal structure with a wider upper part and a narrower lower part. A pair of through pipes 2 are connected and communicated at the bottom end of the respirator 1. A rubber washer 3 is sleeved on the surface of the through pipe 2. A pair of triangular blocks 4 are symmetrically installed on the left and right sides of the inner wall surface of the respirator 1. The overall shape of the triangular block 4 is an obtuse triangle. The inclination of the inclined surface of the triangular block 4 on the side close to the inlet of the respirator 1 is smaller than the inclination of the inclined surface on the side close to the through pipe 2. Spherical cavities 5 are formed on the inner wall surfaces at the front and rear ends of the respirator 1. A rotating ball 6 is rotatably installed inside the spherical cavity 5. Through the above settings, by using different inclinations of the inclined surfaces on both sides of the triangular block 4, it is ensured that when the air flow enters the inside of the respirator 1 from the outside, the speed of the whole process changes from fast to slow and the air volume changes from large to small, so as to ensure that the breathing speed of the patient slows down during the breathing process, and it is ensured that the patient cannot inhale a large amount of air in a short time, resulting in insufficient depth of lung irritation. Further improve the rehabilitation effect of the patient's breathing training; The surface of the rotating ball 6 is provided with arc-shaped notches 7. The number of the arc-shaped notches 7 is two, and the two arc-shaped notches 7 are arranged end to end. The width of the arc-shaped notch 7 gradually increases from one side to the other, and the curvature of the outer arc track of the whole gradually increases synchronously. The upper and lower ends of the surface of the rotating ball 6 are symmetrically provided with diversion notches 8. The arc-shaped notch 7 is communicated with the diversion notch 8. One side corner of the triangular block 4 close to the rotating ball 6 extends towards the inside of the arc-shaped notch 7 on the surface of the rotating ball 6, and the extension distance is equal to the minimum width value of the arc-shaped notch 7. Through the above settings, when the rotating ball 6 rotates with the breathing airflow, the gap range between the arc-shaped notch 7 of the rotating ball 6 part and the corner of the triangular block 4 changes continuously from small to large and from large to small. Therefore, when the patient breathes through the nasal cavity, a variable weak resistance is provided, so as to prevent the patient from inhaling a large amount of air in a short time, thereby prolonging the breathing process and deeply stimulating the lung tissue to achieve the purpose of rehabilitation training; A cavity 9 is arranged inside the respirator 1. The internal space of the cavity 9 is divided by a pair of spherical cavities 5 to form two trapezoidal regions. The widths of the two trapezoidal regions in contact with each other at one end are equal. The width of the other end of the trapezoidal region in the upper half is greater than the width of the other end of the trapezoidal region in the lower half, and the length of the trapezoidal range in the upper half is less than the length of the trapezoidal range in the lower half. An arc-shaped inner wall 10 is formed on the inner wall of the respirator 1 close to the through pipe 2 and between the two through pipes 2. The arching direction of the arc of the arc-shaped inner wall 10 points to the center position of the rotating ball 6. Through the above settings, by using the characteristics of different widths and lengths of the two trapezoidal regions, a large amount of external air flow will enter the inside of the respirator 1 quickly, and at the position of the rotating ball 6, that is, at the dividing line where the two trapezoidal ranges contact, the whole speed of the air flow will slow down and the air flow rate will also decrease synchronously. Thus, during the whole breathing process of the patient, the air flow speed slows down and the amount of air inhaled per unit time will be reduced, so as to increase the duration of the whole breathing cycle of the patient and help deeply stimulate the lungs to achieve the purpose of effectively increasing the rehabilitation training effect.

[0015] The diameter of the rubber gasket 3 is larger than the diameter of the through pipe 2, and the surface of the rubber gasket 3 is provided with frosted lines. The length of the arc-shaped notch 7 is adapted to the thickness of the triangular block 4. The corner of the triangular block 4 is provided with a rounded corner transition. The other side of the triangular block is adapted to the inner wall shape of the respirator, and the track lengths of the two are equal. Through the above settings, it is ensured that the friction between the rubber gasket 3 and the patient's nasal cavity is large, and the stability of the respirator 1 during wearing is improved. At the same time, by setting a rounded corner at the corner of the triangular block 4, it is ensured that when the air flow passes through, it can smoothly pass through the corner of the triangular block 4 and move along its wall surface, which fully improves the overall practicability of the device.

[0016] For specific reference, please refer to the attached Figure 2and appendix Figure 11 The spherical cavity 5 and the rotating ball 6 are in clearance fit, and a layer of lubricating liquid is applied between them.

[0017] The specific implementation method is as follows: The clearance fit between the spherical cavity 5 and the rotating ball 6 can ensure that the rotating ball 6 can rotate inside the spherical cavity 5 after being slightly pushed by an external force, and due to its own inertia, its rotation will not be easily interrupted. At the same time, the clearance fit setting can effectively avoid problems such as jamming of the rotating ball 6 inside the spherical cavity 5.

[0018] Specifically refer to the appendix of the specification Figure 12 The cross-section of the diversion groove opening 8 is triangular, and the diversion groove opening 8 is annularly surrounded and opened on the outer side surface of the rotating ball 6.

[0019] The specific implementation method is as follows: By using the above-mentioned diversion groove opening 8, it is ensured that during the rotation of the rotating ball 6, air flow will enter the inside of the diversion groove opening 8, and under its guiding action, it will enter the inside of the respirator 1 along the surface of the rotating ball 6, thereby ensuring the stability of the rotating ball 6 during rotation, prompting it to always maintain an axial rotation posture, and further improving the practicability of the device.

[0020] The working principle of the present invention: The first step: First, the operator normally assembles each component of the device, then normally uses the device, inserts the two through pipes 2 below the respirator 1 into the two nostrils of the patient respectively, and squeezes and seals the contact surface between the nostrils and the through pipes 2 through the rubber gaskets 3 on the surface of the through pipes 2 and completes the fixing operation of the entire respirator 1.

[0021] Step 2: First, when the patient breathes through the nasal cavity, the external air flow will gradually enter the interior of the cavity 9 through the opening of the respirator 1. Under the guidance of the cavity 9, it gradually penetrates towards the side of the rotating ball 6. At this time, the air flow adopts a single-sided flow mode, passes through the gap reserved between the rotating ball 6 and the triangular block 4, and drives the rotating ball 6 to start rotating through the frictional force generated when the air flow contacts the rotating ball 6. When the rotating ball 6 rotates, due to the design that the volume of the arc-shaped notch 7 on its side increases, and the two arc-shaped notches 7 are arranged end to end on the surface of the rotating ball 6, the gap range between the arc-shaped notch 7 and the corner of the triangular block 4 changes continuously from small to large and then from large to small. Thus, when the patient breathes through the nasal cavity, a variable weak resistance is provided, which prevents the patient from inhaling a large amount of air in a short time, causing the entire breathing cycle to be too rapid and the stroke to be too short, and unable to stimulate the deep part of the lungs. It ensures that the amount of air inhaled by the patient in each breathing cycle is uniform and the stroke is lasting and slow, so as to achieve deep breathing and deeply stimulate the patient's lung tissue. By utilizing the characteristic that the human nasal cavity always breathes unilaterally (in the nasal turbinate mucosa, our blood vessels will undergo autonomous alternating contraction and relaxation, resulting in corresponding alternating changes in the size of the two nasal turbinates and nasal resistance. This change occurs in a cycle every 2-7 hours, which is the reason for the unilateral breathing of the nasal cavity. Simply put, the blood vessels on both sides inside the human nasal cavity will expand and contract, which leads to a change in the resistance inside the two nasal cavities, and then causes one nostril to work and the other nostril to relax, and the unilateral breathing mechanism appears. Medically, it is called the physiological turbinate cycle), it can ensure that the air flow direction inside the respirator 1 is single and will not be disordered. When the patient breathes through the right nostril, the air flow will tend to the right side of the whole respirator 1, thus driving the rotating ball 6 to rotate clockwise. When the patient breathes through the left nostril, the gas flow direction is opposite, effectively ensuring the continuous operation of the respirator 1. Finally, the device completes the auxiliary stimulation and gain effect on the patient's nasal breathing training, and that's it.

[0022] Step 3: First, the operator normally shuts down the device. Then, the operator checks whether the fixation between the various components of the device is normal. Then, replace and repair the aging and severely worn parts inside the device.

[0023] Finally, several points should be noted: First, in the description of this application, it should be noted that unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be understood in a broad sense. It can be a mechanical connection or an electrical connection, or it can be the communication inside two components. It can be directly connected.
