Description

Technical Field

[0001] This invention relates to the field of respiratory rehabilitation training equipment, and more specifically to a pulmonary function rehabilitation training device for respiratory patients. Background Technology

[0002] In the clinical diagnosis and rehabilitation system of respiratory medicine, pulmonary function rehabilitation training is one of the core means to improve the lung function and quality of life of patients with respiratory diseases such as chronic obstructive pulmonary disease and interstitial pneumonia. With the development of respiratory rehabilitation medicine, a variety of pulmonary function rehabilitation training methods have been formed in clinical practice, including manual training methods such as pursed-lip breathing and abdominal breathing, as well as mechanized training using professional equipment. Among them, mechanized training has become an important method widely used in clinical practice because it can more accurately quantify training intensity and improve training compliance. Currently, the most commonly used pulmonary function rehabilitation training equipment in clinical practice is the Ruijiong three-ball breathing trainer. This device mainly consists of a transparent catheter base, three suspended balls of different weights inside, and a mouthpiece. The airflow generated by the patient's exhalation and inhalation lifts the balls. The height and duration of the balls' rise can reflect the patient's expiratory and inspiratory abilities, thereby achieving targeted training of pulmonary function. The three-ball breathing trainer can help patients strengthen their respiratory muscles and increase their vital capacity. It is also simple in structure and easy to operate, making it convenient for patients to carry out rehabilitation training independently outside the hospital. In actual use of the Ruijiong three-ball breathing trainer, water vapor and sputum impurities carried in the patient's exhaled air can enter the device's tubing and adhere to the tubing wall. Long-term accumulation can lead to a decrease in tubing transparency, affecting medical staff and patients' ability to judge the training effect by observing the movement of the balls. To ensure a clear field of vision, the device usually needs to be disassembled and cleaned after use. However, frequent disassembly can easily damage the device's sealing structure, affecting the device's airtightness and thus reducing the accuracy and effectiveness of the training.

[0003] Therefore, this invention proposes a pulmonary function rehabilitation training device for respiratory patients to solve the above problems. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides a pulmonary function rehabilitation training device for respiratory patients. It utilizes the patient's respiratory airflow to drive a cleaning ring to move synchronously and scrape away impurities from the inner wall of the riser. In conjunction with a hydrophobic layer, a hydrophilic layer, and an inclined support ring, it achieves automatic collection of impurities, completing internal cleaning without disassembling the device, thus reducing the frequency of device disassembly and ensuring the airtightness of the device.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A respiratory function rehabilitation training device for respiratory patients includes a respiratory trainer consisting of a breathing tube, a connecting horizontal tube, an exhaust tube, a base, a resistance adjustment component, and three vertical tubes. Each vertical tube is equipped with a flow indicator, which is a cylindrical structure. Each flow indicator has a support ring coaxially fixedly connected to its side wall. The support rings have an inclined cross-section, with the side of the support ring closest to the flow indicator being lower than the other side. Each support ring is detachably connected to a cleaning ring, which is coaxially arranged with the corresponding flow indicator. Each cleaning ring has a hydrophobic layer and a hydrophilic layer arranged sequentially from the outside to the inside. Each flow indicator is equipped with a collection component for storing impurities collected by the cleaning ring.

[0006] The technical principle of the above scheme is as follows: When the patient is performing breathing training, the airflow generated by inhalation and exhalation acts on the bottom and top of the flow indicator, forming an axial thrust and pull on the flow indicator, causing the flow indicator to move axially. The flow indicator drives the support ring and the cleaning ring to move synchronously. During the movement, pressure is generated between the outer wall of the cleaning ring and the inner wall of the riser. The cleaning ring scrapes away impurities on the inner wall of the riser. Because the gas generated by the patient's inhalation and exhalation has a high humidity, the hydrophobic layer on the outside of the cleaning ring reduces the adhesion of impurities, allowing the scraped impurities to fall onto the support ring by their own gravity along the hydrophobic layer. Subsequently, the impurities are collected in the collection component along the inclined surface of the support ring. During this process, viscous substances such as sputum in the impurities are actively adsorbed and collected on the hydrophilic layer.

[0007] The above approach has the following beneficial effects: 1. This method uses the patient's breathing airflow during training as the driving force to clean the inner wall of the riser during each breathing training session, reducing the risk of decreased tube wall transparency caused by long-term accumulation of impurities. 2. This solution improves the accuracy of medical staff and patients in observing the movement of flow indicators during training by keeping the inside of the riser pipe clean; 3. This solution, through automatic cleaning during the breathing training process, reduces the risk of damage to the equipment's sealing structure caused by frequent disassembly, compared to the traditional method of disassembling the equipment for cleaning after each training session.

[0008] Furthermore, each collection component includes a storage tank, which is located at the bottom of the corresponding flow indicator. The storage tank and the flow indicator are threaded together. Each storage tank is connected to a symmetrically arranged inclined channel. The other end of each inclined channel contacts the inner wall of the corresponding cleaning ring near the support ring. The end of the inclined channel connected to the storage tank is lower than the other end.

[0009] Beneficial effects: Impurities that fall off from the cleaning ring enter the inclined channel under the guidance of the support ring, and are collected into the storage tank through the inclined channel. At the same time, the detachable design of the storage tank makes it easy to clean the storage tank.

[0010] Furthermore, each storage compartment has a handle embedded in its bottom.

[0011] Beneficial effect: The handle provides an operating point for rotating the storage tank, improving ease of operation.

[0012] Furthermore, the inner walls of the storage tanks are all coated with an antibacterial coating.

[0013] Beneficial effects: The antibacterial components of the antibacterial coating inhibit the growth and reproduction of bacteria and fungi, reducing the risk of juice spoilage, off-flavors, and secondary contamination in the storage tank.

[0014] Furthermore, the three flow indicators are set to green, yellow, and red, respectively.

[0015] Beneficial effects: By using different colors to create visual contrast during training, patients can quickly identify the progress of their training.

[0016] Furthermore, a filter cover is detachably connected to the connection between the breathing tube and the breathing trainer. The filter cover consists of a primary filter layer, a secondary filter layer, and a high-efficiency filter layer.

[0017] Beneficial effects: Through staged filtration, particulate matter, bacteria and viruses in breathing gas are further removed, reducing the amount of impurities entering the riser, thereby extending the service life of the cleaning ring and storage tank, reducing the frequency of equipment disassembly and cleaning, and improving the equipment's sealing performance.

[0018] Furthermore, the base is equipped with several ultraviolet disinfection lamps corresponding to the riser, and the side wall of the base is equipped with a switch button, which is electrically connected to the ultraviolet disinfection lamps.

[0019] Beneficial effects: After training, the inside of the riser is physically sterilized by ultraviolet disinfection lamps, which also extends the service life of the cleaning ring and reduces the frequency of equipment disassembly.

[0020] Furthermore, the surface of the risers is coated with an anti-fog coating.

[0021] Beneficial effects: The anti-fog coating prevents fogging on the riser surface, improving the clarity of the flow indicator during training.

[0022] Furthermore, the inner walls of the inclined channels are all coated with polytetrafluoroethylene.

[0023] Beneficial effects: The low coefficient of friction and non-stick properties of the polytetrafluoroethylene coating allow impurities to enter the storage tank smoothly under the influence of gravity.

[0024] Furthermore, a buffer layer is fixedly connected to the top of each flow indicator.

[0025] Beneficial effects: The buffer layer absorbs the impact force between the flow indicator and the top of the riser, reducing the wear and tear on the flow indicator and the riser. Attached Figure Description

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] The following detailed description illustrates the specific implementation method: Example 1:

[0032] As attached Figure 1 As shown: A pulmonary function rehabilitation training device for respiratory patients includes a respiratory trainer consisting of a breathing tube 1, a connecting horizontal tube 2, an exhaust tube 3, a base 4, an adjustment component, and three risers 5. The breathing tube 1, the connecting horizontal tube 2, the exhaust tube 3, and the adjustment component are all designed with reference to the Ruijiong three-ball respiratory trainer. Since the patient's breathing gas carries impurities such as water vapor and sputum, these impurities will enter the risers 5 and adhere to the wall of the risers 5. If they accumulate over a long period of time, the transparency of the risers 5 will decrease, affecting the observation of the training effect. Therefore, after training, the risers 5 are disassembled and cleaned to ensure good transparency. However, frequent disassembly can reduce the airtightness of the risers 5, thereby affecting the training effect. To reduce the frequency of disassembly of the breathing trainer and improve its airtightness, as shown in the attached... Figure 2 and attached Figure 3 As shown, the surface of the riser 5 is covered with an anti-fog coating, and the riser 5 is equipped with a flow indicator 6 (the top of the flow indicator 6 is fixedly connected with a buffer layer to absorb the impact force between the flow indicator 6 and the riser 5 and reduce the loss). The flow indicator 6 is set as a cylindrical structure. The side wall of the flow indicator 6 is coaxially bonded with a support ring 7. The cross section of the support ring 7 is inclined. The side of the support ring 7 close to the flow indicator 6 is lower than the other side. A cleaning ring can be detachably connected to the support ring 7. The cleaning ring is coaxially set with the corresponding flow indicator 6. The cleaning ring is set with a hydrophobic layer 8 and a hydrophilic layer 9 from the outside to the inside. The flow indicator 6 is equipped with a collection component for storing the impurities collected by the cleaning ring. As attached Figure 3As shown, the collection components all include storage tanks 10 (the inner walls of the storage tanks 10 are all coated with antibacterial coatings to inhibit the growth and reproduction of bacteria and fungi and reduce the risk of secondary pollution in the storage tanks 10). The storage tanks 10 are all located at the bottom of the corresponding flow indicators 6, and the storage tanks 10 and the flow indicators 6 are threaded together. The storage tanks 10 are all connected to symmetrically arranged inclined channels 11 (the inner walls of the inclined channels 11 are all coated with polytetrafluoroethylene, which reduces the adhesion of impurities by utilizing its low coefficient of friction and non-stick properties). The other end of the inclined channel 11 is in contact with the inner side wall of the corresponding cleaning ring near the support ring 7. The end of the inclined channel 11 connected to the storage tank 10 is lower than the other end. To further reduce the frequency of disassembly and cleaning, as shown in the attached document... Figure 4 As shown, a filter cover 13 is detachably connected to the connection between the breathing tube 1 and the breathing trainer. The filter cover 13 consists of a primary filter layer, a secondary filter layer, and a high-efficiency filter layer.

[0033] The specific implementation process is as follows: When the patient begins pulmonary function rehabilitation training, he first breathes through the breathing tube 1. The exhaled and inhaled airflow passes through the primary filter layer, the secondary filter layer, and the high-efficiency filter layer of the filter hood 13 in sequence. The primary filter layer first intercepts large particulate impurities in the airflow, such as dust and large sputum clumps. The secondary filter layer further filters out medium-sized particles and some bacteria. The high-efficiency filter layer precisely filters out tiny bacteria, viruses, and fine water vapor condensation particles. After these three stages of filtration, the impurity content of the airflow entering the breathing trainer is greatly reduced, reducing the probability of impurities entering the riser tube 5 from the source, thereby reducing the adhesion of impurities to the inner wall of the riser tube 5 and reducing the frequency of equipment disassembly and cleaning. When the airflow enters the riser 5, it exerts a force on the flow indicator 6, causing the flow indicator 6 to move up and down within the riser 5. This movement of the flow indicator 6 drives the support ring 7 to move synchronously. The support ring 7 then drives the cleaning ring to move up and down along the inner wall of the riser 5. The outer wall of the cleaning ring is tightly fitted to the inner wall of the riser 5. During this relative movement, the hydrophobic layer 8 on the outer side of the cleaning ring scrapes away impurities from the riser 5, causing the impurities to adhere to the cleaning ring. The hydrophobic layer 8 utilizes its hydrophobic properties to reduce the adhesion of water vapor, phlegm, and other impurities to the hydrophobic layer 8, allowing the scraped impurities to slide down the hydrophobic layer 8 under their own gravity onto the support ring 7. The inclined surface of ring 7 causes impurities to gather towards the side closer to the flow indicator 6. During the gathering process, the impurities pass through the hydrophilic layer 9 and actively adsorb viscous phlegm and other impurities in the hydrophilic layer 9. Then, the remaining impurities enter the inclined channel 11 and finally enter the storage tank 10. The antibacterial coating on the inner wall of the storage tank 10 inhibits the growth and reproduction of bacteria and fungi in the storage tank 10, preventing impurities from deteriorating, producing odors, and causing secondary pollution in the storage tank 10. The storage tank 10 and the flow indicator 6 are connected by a threaded detachable connection, which facilitates the subsequent periodic disassembly of the storage tank 10 for cleaning and replacement, further improving the cleanliness and hygiene of the equipment. Meanwhile, the anti-fog coating on the surface of riser 5 prevents exhaled hot air from condensing into water mist on the surface of riser 5, improving the transparency of riser 5 and allowing patients and medical staff to clearly observe the movement of flow indicator 6, thereby improving the accuracy of training effect judgment. There is no need to frequently disassemble the equipment to clean the water mist on the surface of riser 5, thus reducing the number of disassembly times, protecting the airtightness of the equipment, and improving the accuracy and effectiveness of training. Throughout the training process, the patient's breathing movements not only complete the rehabilitation training of lung function, but also simultaneously achieve automatic cleaning of the inside of the equipment, reducing the frequency of equipment disassembly and cleaning, reducing the problem of decreased airtightness caused by frequent disassembly, and improving the overall performance and service life of the equipment.

[0034] Example 2:

[0035] As attached Figure 3 and attached Figure 5 As shown, the difference from Embodiment 1 is that each storage tank 10 has a handle 12 embedded in its bottom. The handle 12 provides an operating force point for the rotation of the storage tank 10, thereby improving the ease of operation.

[0036] Example 3:

[0037] As attached Figure 2 As shown, the difference from Embodiment 2 is that the three flow indicators 6 are set to green, yellow and red respectively. The different colors create a visual contrast during the training process, making it easier for patients to quickly identify the completion status of the training.

[0038] Example 4:

[0039] As attached Figure 1 As shown, the difference from embodiment 3 is that the base 4 is equipped with several ultraviolet disinfection lamps corresponding to the riser 5, and the side wall of the base 4 is equipped with a switch button. The switch button and the ultraviolet disinfection lamp are electrically connected. The ultraviolet disinfection lamp and the switch button are preferably Luminus XBT-3535-UVC and Panasonic EVP button, respectively. After the training is completed, the inside of the riser 5 is physically sterilized by the ultraviolet disinfection lamp, which also extends the service life of the cleaning ring and reduces the frequency of equipment disassembly.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
