Description

Technical Field

[0001] This invention relates to the field of respiratory exercise aids, and in particular to a respiratory exercise nursing aid for lung cancer patients. Background Technology

[0002] A respiratory training aid is a device that strengthens respiratory muscles and improves respiratory function by providing controllable resistance or guiding breathing patterns. Its core principle is to simulate the physiological load during breathing, helping users strengthen respiratory muscles such as the diaphragm and intercostal muscles, thereby increasing lung capacity and gas exchange efficiency. It is widely used in medical rehabilitation, sports training, and daily health management.

[0003] Existing breathing training aids can only make coarse adjustments and cannot finely adjust the resistance of blowing for patients with low capacity, such as those with neuromuscular diseases or ALS. Due to severe atrophy of the respiratory muscles, it is difficult to trigger the resistance feedback mechanism of traditional threshold trainers, thus making it impossible to conduct low-resistance blowing training for these patients. Therefore, improvements are needed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a respiratory exercise nursing aid for lung cancer patients.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: This invention discloses a respiratory exercise nursing aid for lung cancer patients, comprising a base, a cylindrical transparent tube vertically mounted on the top of the base, an annular limiting body installed inside the cylindrical transparent tube, and a sphere placed on the top of the annular limiting body. The top of the cylindrical transparent tube is provided with an internally threaded cover, and the internally threaded cover is provided with a coarse adjustment component. The coarse adjustment component includes a threaded post, a lifting post, and a pressure spring. The threaded post is vertically threaded through the top of the internally threaded cover, and the lower end of the threaded post is vertically rotatably connected to the lifting post. A pressure spring is vertically fixedly mounted at the bottom of the lifting post, and the bottom of the pressure spring is fixedly mounted on the top of the sphere. By rotating the threaded post, the lifting post can be driven to move up and down, thereby adjusting the pressure of the pressure spring on the sphere. The top of the cylindrical transparent tube is provided with an externally threaded area, and the outer side of the externally threaded area engages with the internally threaded area on the inner side of the internally threaded cover, realizing a detachable connection between the internally threaded cover and the cylindrical transparent tube. Multiple vent holes are opened through the top of the internally threaded cover to balance the air pressure inside the cylindrical transparent tube and the outside. An air blowing assembly is connected to the cylindrical transparent tube, a liquid storage tank is installed on the top of the base, and a fine adjustment assembly is provided on the liquid storage tank; The fine adjustment assembly includes a circular tube, a push-pull rod, a push-pull handle, and a rubber piston. The cylindrical transparent cylinder and the bottom of the liquid storage tank are connected by a connecting tube. The top of the liquid storage tank is vertically connected to the circular tube, and a rubber piston is slidably installed inside the circular tube. A push-pull rod is vertically installed on the top of the rubber piston, and a push-pull handle is installed on the top of the push-pull rod outside the circular tube. The rubber piston moves up and down along the circular tube to adjust the amount of liquid at the bottom of the cylindrical transparent cylinder.

[0006] As a preferred embodiment of the present invention, a valve is installed on the connecting pipe, and the valve is used to block the flow channel of the connecting pipe to control the liquid flow state between the cylindrical transparent cylinder and the liquid storage tank.

[0007] As a preferred embodiment of the present invention, a guide rod is vertically fixedly installed on the top of the sphere, and the top of the guide rod passes through the pressure spring in sequence and slides into the bottom of the lifting column. The guide rod is used to guide the extension and retraction direction of the pressure spring to prevent the pressure spring from shifting laterally.

[0008] As a preferred embodiment of the present invention, a guide cylinder is vertically fixedly installed on the outer side of the lifting column via a rectangular plate, and a guide post is slidably inserted into the top of the guide cylinder. The top of the guide post is fixedly installed on the inner top of the internal threaded cover. The guide cylinder and the guide post cooperate to guide the up and down movement of the lifting column, ensuring that the lifting column moves stably in the vertical direction.

[0009] In a preferred embodiment of the present invention, the air blowing assembly includes an air outlet and an air blowing tube. The air outlet is fixedly installed at the bottom of the cylindrical transparent tube, and the air blowing tube is vertically installed at the top of the base. One end of the air blowing tube passes through the side wall of the cylindrical transparent tube and communicates with the interior of the air outlet. The other end of the air blowing tube is fitted with an air nozzle on the outside of the cylindrical transparent tube. The patient blows air into the air blowing tube through the air nozzle, and the airflow enters the cylindrical transparent tube through the air outlet.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention forms a dual adjustment mechanism through the cooperation of a coarse adjustment component and a fine adjustment component. The coarse adjustment can quickly adjust the pressure of the pressure spring on the ball by rotating the threaded column, which is suitable for patients in the recovery period with a certain foundation of respiratory muscle strength. The fine adjustment, on the other hand, changes the amount of liquid in the cylindrical transparent tube slightly by sliding the rubber piston in the circular tube, and precisely controls the resistance of airflow through the liquid. Even patients with severe respiratory muscle atrophy and low ability can trigger bubble movement and ball rise and fall feedback through a low resistance threshold, which solves the core pain point of existing technologies that patients with low ability cannot participate in training.

[0012] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0013] Example 1 like Figure 1-4As shown, the present invention provides a respiratory exercise nursing aid for lung cancer patients, including a base 1, a cylindrical transparent tube 2 vertically mounted on the top of the base 1, an annular limiting body 15 installed inside the cylindrical transparent tube 2, and a ball 14 placed on the top of the annular limiting body 15. The top of the cylindrical transparent tube 2 is provided with an internal threaded cover 3, and the internal threaded cover 3 is provided with a coarse adjustment component. The coarse adjustment component includes a threaded column (4), a lifting column (12) and a pressure spring (13). The threaded column (4) is vertically threaded through the top of the internal threaded cover (3), and the lower end of the threaded column (4) rotates vertically with the lifting column (12). The lifting column (12) is vertically fixed at the bottom with a pressure spring (13), and the pressure spring (13) is fixedly installed at the top of the ball (14). By rotating the threaded column (4), the lifting column (12) can be driven to move up and down, thereby adjusting the pressure of the pressure spring (13) on the ball (14). The top of the cylindrical transparent tube (2) is provided with an external thread area (18), and the outer side of the external thread area (18) is threaded with the inner thread of the inner thread cover (3), so as to realize the detachable connection between the inner thread cover (3) and the cylindrical transparent tube (2). The top of the inner thread cover (3) is provided with multiple exhaust holes to balance the air pressure inside the cylindrical transparent tube (2) and the outside. When coarse resistance adjustment is required, rotate the threaded post 4 at the top of the inner threaded cover 3 clockwise or counterclockwise. Since the threaded post 4 and the inner threaded cover 3 are threadedly engaged, the rotation is converted into vertical linear motion of the threaded post 4. When rotating clockwise, the threaded post 4 moves downward, causing the lower end of the rotating lifting post 12 to move downward synchronously. The lifting post 12 generates a compressive force on the pressure spring 13 at the bottom, increasing the spring deformation and thus increasing the downward pressure on the ball 14. When rotating counterclockwise, the threaded post 4 moves upward, and the lifting post 12 moves upward accordingly. The compressive force on the spring decreases, and the pressure on the ball 14 also decreases accordingly. By changing the spring pressure, the airflow pressure threshold required to lift the ball 14 can be adjusted, thus achieving coarse resistance adjustment. The coarse adjustment component can quickly adapt to lung cancer patients at different stages of their condition. For example, patients with weak respiratory muscles in the early postoperative period can reduce the spring pressure and reduce the resistance to blowing by rotating the threaded column 4 counterclockwise. As training progresses and respiratory muscle strength increases, the pressure can be increased by rotating it clockwise to gradually increase the training intensity. The elastic properties of the pressure spring 13 can buffer the instantaneous impact of airflow on the ball 14, avoid rigid contact damage to the patient's respiratory muscles, and improve training safety.

[0014] When the rotating threaded column 4 drives the lifting column 12 to move vertically, the guide cylinder 16, which is fixed to the outside of the lifting column 12 by the rectangular plate, slides along the guide column 17 in sync. When the lifting column 12 moves downward, the guide cylinder 16 extends downward along the guide column 17; when the lifting column 12 moves upward, the guide cylinder 16 retracts upward along the guide column 17; the top of the guide column 17 is fixed to the top of the inner threaded cover 3, and its vertical posture can limit the lateral rotation or offset of the guide cylinder 16, thereby constraining the movement trajectory of the lifting column 12. The cooperation between the guide cylinder 16 and the guide column 17 ensures that the lifting column 12 always moves vertically, avoiding the deflection of the lifting column 12 caused by the torque generated by the rotation of the threaded column 4, thereby ensuring that the pressure of the pressure spring 13 on the ball 14 is evenly distributed. For lung cancer patients who rely on precise resistance adjustment, this structure can improve the adjustment accuracy of the coarse adjustment component and avoid the problem of the actual resistance not matching the set resistance due to structural offset. At the same time, the sliding cooperation can reduce the wear of the lifting column 12 and extend the overall service life of the device.

[0015] Please see Figure 4 Furthermore, the top of the cylindrical transparent tube 2 is provided with an external thread area 18, and the outer side of the external thread area 18 is engaged with the internal thread of the inner side of the internal thread cover 3, so as to realize the detachable connection between the internal thread cover 3 and the cylindrical transparent tube 2. The top of the internal thread cover 3 is provided with multiple vent holes to balance the air pressure inside the cylindrical transparent tube 2 and the outside. In an embodiment of the present invention, when it is necessary to install or remove the internal thread cover 3, the internal thread cover 3 is rotated clockwise, and the internal thread on its inner side is disengaged from the external thread area 18 at the top of the cylindrical transparent tube 2, so that the internal thread cover 3 can be removed; the internal thread cover 3 is rotated counterclockwise, and the internal thread and the external thread area 18 are tightly engaged, so as to fix the internal thread cover 3; during the patient's air blowing training, the air pressure in the cylindrical transparent tube 2 increases with the airflow input, and excess gas can be quickly discharged through the exhaust hole at the top of the internal thread cover 3, so that the air pressure in the transparent tube is balanced with the external atmospheric pressure; The threaded inner thread cap 3 is easy to disassemble, allowing caregivers to regularly clean the sphere 14, annular retainer 15, and air outlet 19 inside the cylindrical transparent tube 2, reducing the risk of infection caused by bacterial growth inside the device for lung cancer patients. The design of the vent hole can prevent excessive air pressure inside the transparent tube, preventing patients from having to overcome additional air pressure resistance when blowing air, reducing the burden on respiratory muscles, and is especially suitable for lung cancer patients with weak respiratory function. In addition, the sealing of the threaded connection can prevent liquid from leaking from the top of the transparent tube during training, improving the safety of use.

[0016] An air blowing component is connected to the cylindrical transparent tube 2, and a liquid storage tank 5 is installed on the top of the base 1, and a fine adjustment component is provided on the liquid storage tank 5; The fine adjustment assembly includes a circular tube 6, a push-pull rod 7, a push-pull handle 8, and a rubber piston 11. The bottom of the cylindrical transparent cylinder 2 and the liquid storage tank 5 are connected by a connecting tube 9. The top of the liquid storage tank 5 is vertically connected to the circular tube 6, and the rubber piston 11 is slidably installed inside the circular tube 6. The top of the rubber piston 11 is vertically installed with the push-pull rod 7, and the top of the push-pull rod 7 is located outside the circular tube 6 with the push-pull handle 8. The rubber piston 11 moves up and down along the circular tube 6 to adjust the amount of liquid at the bottom of the cylindrical transparent cylinder 2. In an embodiment of the present invention, when it is necessary to adjust the resistance of breathing exercises for lung cancer patients, especially those with low respiratory capacity due to respiratory muscle atrophy, the fine adjustment component is first operated. The push-pull handle 8 is held and applied vertically, causing the push-pull rod 7 to move synchronously. The rubber piston 11 connected to the lower end of the push-pull rod 7 slides vertically within the circular tube 6. If the push-pull handle 8 is pushed downwards, the rubber piston 11 compresses the space within the liquid storage tank 5, and the liquid in the tank flows into the bottom of the cylindrical transparent cylinder 2 through the connecting pipe 9, increasing the amount of liquid in the transparent cylinder. If the push-pull handle 8 is pulled upwards... The handle 8 and rubber piston 11 expand the space inside the storage tank, and the liquid in the transparent tube flows back into the storage tank, reducing the amount of liquid in the transparent tube. After the liquid volume is adjusted, the patient blows air into the air tube 20 through the air nozzle of the air blowing assembly. The airflow is delivered through the air tube 20 to the air outlet 19 at the bottom of the cylindrical transparent tube 2, and disperses into the liquid from the air outlet 19, generating upward air pressure. When the air pressure reaches a certain threshold, it can achieve the training effect, forming an airflow channel that passes through the annular limiting body 15 and finally exits from the exhaust hole of the internal threaded cover 3. The sliding of the rubber piston 11 enables micro-adjustment of the liquid volume, allowing precise control of the airflow resistance through the liquid. This perfectly suits the needs of low-resistance, finely adjustable lung cancer patients, such as those with neuromuscular diseases or severe respiratory muscle atrophy, addressing the problem that traditional assistive devices cannot trigger resistance training. The transparent cylindrical tube 2 allows for a direct view of liquid fluctuations and the rising and falling of the sphere 14, facilitating real-time observation of training effects by patients or caregivers and enhancing patients' confidence in training. The overall structure is primarily mechanically driven, without complex electronic components, making it simple to operate and with a low failure rate, suitable for long-term home or clinical care. A certain amount of sterilizing and disinfecting liquid can be added to the liquid to ensure that bacteria cannot grow in the liquid; When training patients with intellectual disabilities, it is necessary to open the closed passage between the sphere 14 and the annular limiting body 15 to ensure that the cylindrical transparent tube 2 can be ventilated normally without damaging the resistance of the sphere 14.

[0017] Please see Figure 1 Furthermore, a valve 10 is installed on the connecting pipe 9, and the valve 10 is used to block the flow channel of the connecting pipe 9 in order to control the liquid flow state between the cylindrical transparent cylinder 2 and the liquid storage tank 5. In an embodiment of the present invention, when adjusting the liquid volume, the control knob of valve 10 is manually rotated to switch the valve core of valve 10 from the closed state to the open state, the flow channel of connecting pipe 9 is opened, and the liquid can flow freely between the cylindrical transparent cylinder 2 and the liquid storage tank 5; after the liquid volume in the transparent cylinder is adjusted to the target value, the valve 10 knob is rotated in the opposite direction, the valve core is reset and the channel of connecting pipe 9 is blocked, and the liquid is fixed in the respective cavities of the transparent cylinder and the storage tank, and no longer flows. The on / off control of valve 10 can precisely lock the adjusted liquid volume, preventing the liquid from flowing back and forth in the connecting tube 9 during the patient's breathing training, which would cause the resistance to fluctuate and ensure the stability of the training resistance. At the same time, when it is necessary to clean the assist device or change the liquid, such as changing to sterile water to avoid infection, opening valve 10 can quickly empty the liquid in the transparent tube, simplifying the cleaning and maintenance process and reducing the risk of lung cancer patients developing lung infections due to incomplete device cleaning.

[0018] Please see Figure 4 Furthermore, a guide rod 21 is vertically fixedly installed on the top of the ball 14, and the top of the guide rod 21 passes through the pressure spring 13 in sequence and slides into the bottom of the lifting column 12. The guide rod 21 is used to guide the extension and retraction direction of the pressure spring 13 to prevent the pressure spring 13 from shifting laterally. In an embodiment of the present invention, when the pressure spring 13 is stretched and deformed by the lifting column 12, the guide rod 21 fixed at the top of the ball 14 slides vertically along the reserved hole at the bottom of the lifting column 12; when the spring is stretched, the guide rod 21 extends outward from the lifting column hole; when the spring is compressed, the guide rod 21 retracts into the lifting column hole; at the same time, when the patient blows air to lift the ball 14, the guide rod 21 rises synchronously with the ball 14, limiting the lateral displacement of the ball 14 and ensuring that the ball 14 is always vertically aligned with the center hole of the annular limiting body 15. The guide rod 21 can effectively constrain the extension and retraction direction of the pressure spring 13, preventing the spring from being subjected to force on one side due to lateral deviation, thereby preventing uneven force, jamming or tilting of the ball 14, and ensuring the accuracy of resistance feedback. For lung cancer patients with low capacity, stable resistance feedback can avoid ineffective blowing due to device malfunction and improve training efficiency. In addition, the presence of the guide rod 21 can extend the service life of the pressure spring 13 and reduce wear caused by spring deviation.

[0019] Please see Figure 1Furthermore, the air blowing assembly includes an air outlet 19 and an air blowing tube 20. The air outlet 19 is fixedly installed at the bottom of the cylindrical transparent tube 2, and the air blowing tube 20 is vertically installed at the top of the base 1. One end of the air blowing tube 20 passes through the side wall of the cylindrical transparent tube 2 and is connected to the inside of the air outlet 19. The other end of the air blowing tube 20 is located on the outside of the cylindrical transparent tube 2 and is equipped with an air blowing nozzle. The patient blows air into the air blowing tube 20 through the air blowing nozzle, and the airflow enters the cylindrical transparent tube 2 through the air outlet 19. In an embodiment of the present invention, during training, lung cancer patients place their mouths against the mouthpiece at the end of the air inflator 20 and slowly blow air into the air inflator 20; the airflow flows along the cavity of the air inflator 20, passes through the side wall of the cylindrical transparent tube 2, and enters the air outlet 19 fixed at the bottom of the transparent tube; the air outlet 19 is provided with multiple sets of small air holes, which can disperse the airflow into uniform small bubbles, avoiding splashing caused by a single strong airflow impacting the liquid; the dispersed bubbles move upward and generate upward pressure on the liquid. When the pressure reaches a set threshold, it lifts the ball 14 on the annular limiting body 15 and rises from the gap between the ball 14 and the limiting body, and finally is discharged through the exhaust hole of the internal threaded cover 3; The dispersed airflow design of the air outlet 19 can prevent liquid splashing and contamination of the patient's respiratory tract or clothing, improving user comfort; the blowing tube 20 is vertically installed on the top of the base 1, and the blowing nozzle is located on the outside of the transparent tube, allowing patients to train in a sitting or semi-reclining position, which is suitable for the postoperative bed rest or semi-reclining position requirements of lung cancer patients; the process of airflow transforming into bubbles is highly visualized, and patients can intuitively perceive their own breathing strength by observing the number of bubbles and the rising and falling state of the spheres, enhancing the initiative and fun of training, and helping to adhere to breathing exercises in the long term.

[0020] The workflow of this embodiment is as follows: 1. Instrument initialization and fluid filling: First, prepare the instrument by rotating the inner thread cap 3 counterclockwise to disengage it from the outer thread area 18 at the top of the cylindrical transparent tube 2 and opening the transparent tube; inject sterile water into the cylindrical transparent tube 2, and then tighten the inner thread cap 3 clockwise to ensure the thread is sealed. At the same time, check whether the vent hole at the top of the inner thread cap 3 is unobstructed to prevent air pressure blockage.

[0021] 2. Fine-tuning of resistance: Open valve 10 on connecting pipe 9 to connect the cylindrical transparent cylinder 2 with the liquid storage tank 5; the nurse holds the push-pull handle 8 of the fine-tuning component and applies vertical force according to the patient's respiratory muscle strength: to reduce resistance, pull the push-pull handle 8 upward, causing the push-pull rod 7 and rubber piston 11 to move upward in the circular tube 6, expanding the space inside the liquid storage tank 5, and the liquid in the cylindrical transparent cylinder 2 flows into the storage tank through the connecting pipe 9, reducing the amount of liquid in the transparent cylinder. The less liquid, the less resistance when the airflow passes through; to slightly increase resistance, push the push-pull handle 8 downward, the rubber piston 11 compresses the space in the storage tank, and the liquid flows back into the transparent cylinder, increasing the amount of liquid; once the amount of liquid is adjusted to the target value, if the liquid in the transparent cylinder only covers the top of the exhalation head for patients with low capacity, close valve 10 to lock the amount of liquid and avoid resistance fluctuations caused by liquid flow during training.

[0022] 3. Coarse Resistance Adjustment: If the patient's respiratory muscle strength is slightly stronger, resistance needs to be supplemented based on fine adjustment. The threaded column 4 at the top of the inner threaded cover 3 can be rotated: Rotating the threaded column 4 clockwise moves it downward along the thread structure of the inner threaded cover 3, causing the lower end of the rotating lifting column 12 to move downward simultaneously. The lifting column 12 compresses the pressure spring 13 at the bottom, increasing the downward pressure of the spring on the ball 14. At this time, the patient needs a greater airflow pressure to lift the ball 14, and the resistance increases accordingly. If the patient has difficulty blowing, rotate the threaded column 4 counterclockwise, and the lifting column 12 moves upward, reducing the spring pressure and lowering the resistance. During the adjustment process, the guide cylinder 16 on the outside of the lifting column 12 slides synchronously along the guide column 17 to ensure the vertical stability of the lifting column 12 and avoid spring pressure deviation.

[0023] 4. Patient breathing training: The patient assumes a comfortable sitting or semi-recumbent position, places their mouth against the mouthpiece at the end of the air inhalation tube 20, and slowly and evenly blows air into the air inhalation tube 20; the airflow is delivered along the air inhalation tube 20 to the air outlet 19 at the bottom of the cylindrical transparent tube 2, and disperses into uniform small bubbles through the small air vents of the air outlet 19; when the bubbles move upward, they generate upward air pressure on the liquid; the airflow passes through the gap between the sphere 14 and the annular limiting body 15, and finally exits from the exhaust hole of the internal threaded cover 3, completing one effective exhalation training; during the training, the guide rod 21 at the top of the sphere 14 slides along the bottom of the lifting column 12 to prevent the sphere 14 from shifting laterally and to ensure the stability of the airflow channel.

[0024] Training Completion and Equipment Maintenance: After training, first close valve 10, then open the internal threaded cover 3 counterclockwise to empty the liquid in the cylindrical transparent cylinder 2; disassemble the connection between the air tube 20 and the air outlet 19, and rinse the air tube 20, air outlet 19, cylindrical transparent cylinder 2, and ball 14 with sterile water to remove any liquid residue; after drying all components, reassemble them to ensure smooth sliding between the guide cylinder 16 and guide column 17, and between the guide rod 21 and lifting column 12, in preparation for the next use and to avoid bacterial growth that could lead to lung infection in lung cancer patients.

[0025] This invention forms a dual adjustment mechanism through the cooperation of a coarse adjustment component and a fine adjustment component. The coarse adjustment can quickly adjust the pressure of the pressure spring on the ball by rotating the threaded column, which is suitable for patients in the recovery period with a certain foundation of respiratory muscle strength. The fine adjustment, on the other hand, changes the amount of liquid in the cylindrical transparent tube slightly by sliding the rubber piston in the circular tube, and precisely controls the resistance of airflow through the liquid. Even patients with severe respiratory muscle atrophy and low ability can trigger bubble movement and ball rise and fall feedback through a low resistance threshold, which solves the problem that patients with low ability cannot participate in training in the existing technology.

[0026] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
