Description

Technical Field

[0001] This utility model relates to the field of medical monitoring equipment, specifically to a module for collecting gas flow rate. Background Technology

[0002] Accurate monitoring of respiration is crucial in the fields of healthcare and rehabilitation training. However, current respiratory monitoring technologies have several shortcomings. Firstly, traditional respiratory monitoring methods largely rely on simple instruments, such as spirometers for basic lung capacity measurement. These instruments often provide limited information and cannot achieve continuous and dynamic monitoring of gas flow during respiration. In some respiratory training scenarios, such as rehabilitation training for patients with chronic obstructive pulmonary disease (COPD), asthma, or respiratory regulation training for athletes, knowing only a single indicator like lung capacity is far from sufficient. Secondly, while some existing gas flow monitoring devices can measure gas flow, they have several problems. First, their complex structure, large size, and portability limit their use in different scenarios, especially for users who need to conduct mobile training or rehabilitation training in different locations. Secondly, some devices can interfere with the normal use of respiratory training equipment during measurement. For example, some gas flow monitoring devices, when installed on respiratory training equipment, can alter the original airflow path, requiring users to overcome additional resistance during training and affecting the training effect. Furthermore, some monitoring devices have incomplete data acquisition and transmission functions, making it difficult to easily transmit data to external devices for analysis and storage. This hinders doctors or coaches from adjusting training or treatment plans based on real-time data. In addition, some devices have power supply issues; devices with built-in power supplies often increase weight and cost, and require regular battery replacements. This not only increases operating costs but may also interrupt monitoring due to battery depletion, causing inconvenience to users. In summary, existing respiratory monitoring technologies struggle to meet the needs for accurate, convenient, continuous, and non-interfering monitoring of inhalation and exhalation. Therefore, this invention aims to provide an improved gas flow acquisition module to solve the aforementioned problems. Utility Model Content

[0029] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Example 1

[0031] like Figure 1-4 As shown, a module for collecting gas flow includes a vent pipe 1, a carrier box 3 connected to the side of the vent pipe 1, a cover 6 connected to the opening of the carrier box 3, and a controller 5 connected inside the carrier box 3. The controller 5 includes a USB module 501, a microcontroller module 502, and an analog voltage data acquisition module 503. The USB module 501 and the analog voltage data acquisition module 503 are respectively connected to the microcontroller module 502. The USB module 501 is connected to an external smart device 7. The analog voltage data acquisition module 503 is connected to a gas flow sensor 2 that penetrates the carrier box 3 and is inserted into the vent pipe 1.

[0032] Working principle:

[0033] When the gas flow acquisition module is connected to the breathing training device and starts working, the user performs breathing training, and the gas flows through the ventilation tube 1.

[0034] Gas flows through the surface of gas flow sensor 2 inside vent pipe 1. Gas flow sensor 2 is a hot-film gas flow sensor, and its working principle is based on the principle of heat transfer. When the gas flows, it carries away or brings heat, causing a change in the temperature distribution on the sensor, which in turn generates an analog voltage signal related to the gas flow rate.

[0035] The analog voltage data acquisition module 503 is connected to the gas flow sensor 2 and is responsible for acquiring the analog voltage signal generated by the gas flow sensor 2.

[0036] The acquired analog voltage signal is transmitted to the microcontroller module 502. Upon receiving the analog voltage signal, the microcontroller module converts and analyzes the signal according to a pre-set program and algorithm. This microcontroller module integrates an analog-to-digital converter to convert the analog signal into a digital signal, and then, based on the corresponding mathematical model and calibration data, converts the digital signal into the corresponding gas flow rate data.

[0037] The converted gas flow data is transmitted to an external smart device 7 via USB module 501. The external smart device 7 can be a mobile phone or tablet, etc. The data is transmitted to the external smart device 7 via USB communication protocol.

[0038] The corresponding software in the external smart device 7, such as the specially developed respiratory monitoring software, receives the gas flow data and further processes the data, such as displaying it to the user in the form of charts, data lists, etc. The user can intuitively observe the changes in gas flow during the breathing process, and can also store the data for subsequent in-depth analysis and evaluation of the breathing situation, providing data basis for medical diagnosis, rehabilitation training and sports training.

[0039] Example 2

[0040] like Figure 1-4 As shown, a module for collecting gas flow includes a vent pipe 1, a carrier box 3 connected to the side of the vent pipe 1, a cover 6 connected to the opening of the carrier box 3, and a controller 5 connected inside the carrier box 3. The controller 5 includes a USB module 501, a microcontroller module 502, and an analog voltage data acquisition module 503. The USB module 501 and the analog voltage data acquisition module 503 are respectively connected to the microcontroller module 502. The USB module 501 is connected to an external smart device 7. The analog voltage data acquisition module 503 is connected to a gas flow sensor 2 that penetrates the carrier box 3 and is inserted into the vent pipe 1.

[0041] The vent tube 1, the carrier box 3, and the box cover 6 are all made of plastic.

[0042] The advantages of the above settings are:

[0043] Cost-effectiveness:

[0044] Plastic materials are generally cheaper than other materials such as metals and ceramics, which can significantly reduce the manufacturing cost of this gas flow acquisition module. For mass production, lower material costs can increase profit margins, making the product more price-competitive in the market, easier to promote and popularize, and able to meet the needs of different user groups, including medical institutions, rehabilitation centers, and home users. The cost advantage is even more pronounced in large-scale application scenarios.

[0045] Lightweight:

[0046] The relatively low density of plastic makes the overall structure consisting of the ventilation tube 1, the carrier box 3, and the lid 6 lightweight. In practical use, the light weight facilitates portability and operation. For example, for users or medical personnel who need to use the module in different environments, the lightweight design makes it easy to connect to different breathing training devices without adding excessive extra weight to the equipment. This avoids affecting the normal use of the breathing training equipment and the user's operating experience due to weight issues, and also facilitates the movement and transportation of the equipment.

[0047] Ease of processing:

[0048] Plastic products have good plasticity and are easy to process and manufacture through molding processes such as injection molding and blow molding. This ease of processing allows manufacturers to more easily produce vent pipes and carrier boxes with complex shapes and precise structures. It also enables the vent pipe and carrier box to be injection molded as a single piece, ensuring a tight connection and structural stability between the two, reducing assembly errors between components, improving production efficiency, ensuring product consistency and quality stability, and meeting the needs of large-scale industrial production.

[0049] Chemical stability:

[0050] In typical operating environments, most plastics exhibit good chemical stability and are not prone to chemical reactions with common gas components. When gas flows through the ventilation tube 1, the plastic material does not react with the gas, ensuring that the gas composition and properties remain unaffected. This guarantees the accuracy of the gas flow sensor measurement, avoids measurement errors caused by changes in gas composition due to chemical reactions, and provides reliable data support for respiratory monitoring.

[0051] Electrical insulation:

[0052] The gas flow acquisition module contains electronic components such as a controller. The excellent electrical insulation properties of the plastic prevent damage to the internal circuitry due to leakage, ensuring the electrical safety of the module, reducing the risk caused by electrical faults, improving the overall reliability and service life of the module, and avoiding potential harm to users due to electrical safety issues.

[0053] Corrosion resistance:

[0054] Compared to metal materials, plastic products generally have better corrosion resistance, able to withstand the erosion of some corrosive gases or environmental factors. This is crucial for gas flow acquisition modules that are used for extended periods in various environments. For example, in medical environments where humidity and chemical volatilization may occur, plastic materials can maintain good performance, extend the module's lifespan, reduce structural damage and performance degradation caused by corrosion, and ensure the module's long-term stable operation.

[0055] The vent pipe 1 and the carrier box 3 are integrally injection molded.

[0056] The advantages of the above settings are:

[0057] Structural stability:

[0058] The integrated injection molding process manufactures the ventilator 1 and the carrier box 3 as a single unit, eliminating the gaps and interfaces that may exist in traditional connection methods. This avoids problems such as loosening and leakage at the connection points due to long-term use or different environmental conditions, ensuring the structural integrity of the gas flow acquisition module, making the entire device more robust and durable, and guaranteeing that gas will not leak from the connection points during respiratory monitoring, thereby improving the accuracy and reliability of the monitoring data.

[0059] Good sealing performance:

[0060] The one-piece injection molding structure has no additional connection points, which better ensures the seal between the vent pipe and the carrier box compared to other connection methods. Good sealing is crucial for the gas flow acquisition module, as gas leakage can severely affect the accuracy of the gas flow sensor measurement, potentially leading to deviations in the results. One-piece injection molding effectively prevents gas leakage from the connection between the vent pipe 1 and the carrier box 3, ensuring that the gas flows only along the predetermined channel, guaranteeing the stability of the gas flow and the accuracy of the flow measurement.

[0061] Processing efficiency and cost:

[0062] In the manufacturing process, one-piece injection molding can improve production efficiency. By completing the manufacturing of the vent pipe 1 and the carrier box 3 in a single injection molding operation, the time and labor costs required for traditional multi-part assembly are reduced, and additional connection processes such as assembly, welding, or fastening are avoided, thereby lowering production costs. Furthermore, one-piece injection molding can reduce errors caused by assembly operations, ensuring product consistency and quality stability, and helping to improve the product qualification rate. This advantage is even more significant in large-scale production.

[0063] Design flexibility:

[0064] The one-piece injection molding process allows for more flexible design of the shape and size of the ventilation tube 1 and the carrier box 3 during the design phase to meet different usage requirements and application scenarios. For example, the shape of the ventilation tube and the carrier box structure can be designed to match the interface shape of the specific breathing training equipment, achieving better compatibility and adaptability. Furthermore, special structural features, such as reinforcing ribs and positioning structures, can be integrated during the injection molding process as needed to further improve the strength and performance of the structure while ensuring the overall aesthetic appearance.

[0065] Advantages of fluid dynamics:

[0066] The integrated injection-molded vent tube 1 and carrier box 3 allow for a smooth transition, reducing airflow disturbances caused by the connection structure. When gas flows within the vent tube, the airflow enters the carrier box area more smoothly, avoiding turbulence and pressure loss at the connection point. This results in a more stable and uniform gas flow throughout the channel, which has a positive impact on the accurate measurement of gas flow by the gas flow sensor, helping to improve the accuracy and reliability of the measurement.

[0067] The carrier box 3 is adhesively connected to the box cover 6.

[0068] The advantages of the above settings are:

[0069] Good sealing performance:

[0070] The adhesive connection creates a relatively sealed space between the carrier box 3 and the cover 6. For the gas flow acquisition module, which contains electronic components such as the controller 5, good sealing performance prevents external dust, moisture, and other impurities from entering the carrier box 3, avoiding damage to the internal electronic components and ensuring their normal operation and lifespan. Simultaneously, good sealing performance also helps ensure the accuracy of gas flow measurement, prevents external gas from interfering with the stable flow of internal air, and ensures that the measurement environment of the gas flow sensor 2 is unaffected by external factors.

[0071] Ease of assembly:

[0072] Adhesive bonding is a relatively simple process that does not require complex mechanical connecting parts, saving assembly time and costs during assembly. Furthermore, this connection method eliminates the need for additional processing of the carrier box 3 and the lid 6, reducing processing steps, improving production efficiency, and making it particularly suitable for large-scale production. It also avoids structural defects that may be introduced during processing, ensuring the overall quality of the product.

[0073] Appearance integrity and aesthetics:

[0074] Compared to other connection methods, adhesive bonding makes the connection between the carrier box 3 and the cover 6 smoother, without any protruding connecting parts. This makes the overall appearance of the gas flow acquisition module simpler and more aesthetically pleasing. For some application scenarios where appearance is a requirement, it can improve the overall visual effect of the product and enhance the user experience.

[0075] Connection reliability:

[0076] Choosing a suitable adhesive can create a strong connection between the carrier box 3 and the cover 6, ensuring that the cover 6 will not accidentally detach during normal use and that the controller 5 and other components inside the carrier box 3 remain in a safe and stable state. Furthermore, the adhesive can fill the tiny gaps between the carrier box 3 and the cover 6, further enhancing the tightness and stability of the connection and making the entire structure more reliable.

[0077] V. Flexibility and Adaptability:

[0078] Adhesive bonding offers a degree of flexibility, allowing for the selection of different adhesive types to suit various design requirements and operating environments, adapting to different carrier box 3 and lid 6 materials and application scenarios. For example, for gas flow acquisition modules that need to operate under varying temperatures, humidity levels, or chemical conditions, appropriate temperature-resistant, moisture-resistant, or chemically resistant adhesives can be selected to ensure good performance under diverse conditions. Furthermore, adhesive bonding makes it easier to achieve tight connections for carrier boxes and lids with special shapes or structures, without being limited by shape.

[0079] The carrier box 3 has a groove 4 corresponding to the USB module 501.

[0080] The advantages of the above settings are:

[0081] Protect the USB module:

[0082] The groove 4 provides a certain degree of physical protection for the USB module 501. During daily use, transportation, or storage, the presence of the groove prevents the USB module 501 from being easily subjected to external impacts, friction, or pressure, thus avoiding damage or deformation of the USB interface due to external physical factors, extending the service life of the USB module 501, and ensuring its reliable connection with external smart devices.

[0083] Positioning and stabilizing functions:

[0084] The groove 4 is designed to position the USB module 501, ensuring it is correctly positioned within the housing 3 and preventing displacement or movement during use. This guarantees stability when the USB module 501 connects to the external smart device 7, reducing data transmission interruptions or anomalies caused by unstable connections and ensuring reliable and continuous data transmission.

[0085] Compactness of the overall structure:

[0086] This makes the overall structure of the USB module 501 and the carrier box 3 more compact, and makes the appearance of the entire gas flow acquisition module more regular. It also prevents the USB module 501 from protruding from the surface of the carrier box 3, reducing the risk of accidental damage caused by protruding parts. At the same time, it is convenient to integrate the gas flow acquisition module into other devices or systems, improving space utilization. Especially in some application scenarios with strict space requirements, it helps to achieve the miniaturization and compact design of the device.

[0087] Reduce external interference:

[0088] Because the USB module 501 is located within the recess 4, the impact of external electromagnetic interference on the USB module 501 can be reduced to some extent. Since external electromagnetic signals may interfere with data transmission, placing the USB module 501 within the recess 4 reduces the influence of external electromagnetic signals, ensuring the quality of data transmission between the USB module 501 and the external smart device 7, improving the stability and reliability of the entire system, and ensuring that gas flow data can be accurately and stably transmitted to the external smart device for analysis and processing.

[0089] Example 3

[0090] like Figure 1-4 As shown, a module for collecting gas flow includes a vent pipe 1, a carrier box 3 connected to the side of the vent pipe 1, a cover 6 connected to the opening of the carrier box 3, and a controller 5 connected inside the carrier box 3. The controller 5 includes a USB module 501, a microcontroller module 502, and an analog voltage data acquisition module 503. The USB module 501 and the analog voltage data acquisition module 503 are respectively connected to the microcontroller module 502. The USB module 501 is connected to an external smart device 7. The analog voltage data acquisition module 503 is connected to a gas flow sensor 2 that penetrates the carrier box 3 and is inserted into the vent pipe 1.

[0091] Gas flow sensor 2 is a hot-film gas flow sensor.

[0092] The advantages of the above settings are:

[0093] High-precision measurement:

[0094] Hot-film gas flow sensors offer high measurement accuracy. They determine gas flow rate by measuring the effect of gas flow on the heat transfer of a heating element within the sensor. They are sensitive to even minute changes in gas flow rate, providing precise measurement results. This is crucial for applications requiring accurate monitoring of respiratory function, helping to accurately assess respiratory function and providing doctors, rehabilitation therapists, and users themselves with more reliable data to better understand subtle changes in breathing.

[0095] Rapid response:

[0096] This type of sensor features a rapid response, enabling it to quickly detect changes in gas flow rate. When gas begins to flow or its flow rate changes, the hot-film gas flow sensor can detect this change and output a corresponding signal within a very short time. This allows the entire gas flow acquisition module to track the dynamic gas flow during respiration in real time and accurately, without significant measurement delay. It ensures accurate reflection of real-time changes in gas flow even under conditions of rapid breathing frequency or complex breathing patterns, providing timely data support for monitoring respiratory status.

[0097] Wide measurement range:

[0098] Hot-film gas flow sensors typically have a wide measurement range, capable of measuring gas flow from low to high speeds, meeting the measurement needs of different breathing intensities. Whether it's the low gas flow during normal breathing or the high gas flow generated during strenuous exercise or breathing training, accurate measurements can be obtained within their measurement range. They are suitable for gas flow monitoring in different user groups and different breathing training scenarios, demonstrating strong adaptability.

[0099] Good linearity:

[0100] Its output signal typically exhibits a good linear relationship with the gas flow rate, meaning there is a relatively simple linear correspondence between the sensor's output signal and the actual gas flow rate. This linearity facilitates signal processing and data analysis, allowing the sensor's output signal to be converted into actual gas flow rate data using a simple linear transformation formula. This reduces complex calibration and data processing procedures, simplifies the data processing algorithms in the microcontroller module, and improves the overall data processing efficiency and accuracy of the gas flow acquisition module.

[0101] Stability and reliability:

[0102] Hot-film gas flow sensors exhibit good stability during long-term use, and their performance is not easily affected by environmental factors. Under normal operating conditions, their measurement performance can remain stable for a long time, ensuring the consistency and reliability of measurement data, reducing measurement errors caused by fluctuations in sensor performance, and providing a stable data source for long-term respiratory monitoring and data analysis.

[0103] No moving parts:

[0104] This sensor typically contains no moving parts, avoiding the problems of measurement accuracy and lifespan affected by wear, jamming, or damage of mechanical components, compared to some traditional mechanical gas flow sensors. The absence of moving parts simplifies its structure, increases reliability, reduces maintenance costs and repair needs, improves the overall reliability and lifespan of the gas flow acquisition module, and reduces noise generated by component movement, preventing interference with measurement results.

[0105] The 502 microcontroller module is an N32G43 microcontroller module.

[0106] The advantages of the above settings are:

[0107] Stable performance:

[0108] The N32G43 microcontroller module boasts excellent performance stability, maintaining a stable operating state even during extended periods of operation.

It can efficiently convert the analog voltage signal acquired by the analog voltage data acquisition module 503 into digital data, using built-in algorithms to transform it into useful gas flow data. This avoids resource waste due to excessive processing power, as well as data processing delays due to insufficient processing power, ensuring the efficient operation of the entire system.

[0111] Low power consumption:

[0112] The N32G43 microcontroller module has low power consumption, which is crucial for gas flow acquisition modules that rely on external smart devices for power and lack their own power supply. Low power consumption reduces overall system energy consumption, alleviates the power burden on external smart devices, extends their battery life, and also helps reduce module heat generation, improving system stability and reliability. This makes it particularly suitable for applications requiring long-term continuous respiratory monitoring.

[0113] Abundant peripheral interfaces:

[0114] This microcontroller module is typically equipped with a rich set of peripheral interfaces, facilitating connection and communication with other modules. For example, it can easily connect to analog voltage data acquisition module 503, USB module 501, etc., to achieve data acquisition, processing, and transmission. The abundant interfaces also facilitate system expansion and upgrades, allowing for the addition of other functions in subsequent development, such as connecting more sensors or performing other control functions, thus improving the system's scalability and flexibility.

[0115] Cost-effectiveness:

[0116] While meeting system performance requirements, the N32G43 microcontroller module offers a cost advantage. Its relatively reasonable price helps reduce the overall manufacturing cost of the gas flow acquisition module, making the product more competitive in the market. Simultaneously, it provides developers with an economical hardware option that is suitable for large-scale production and widespread application, while ensuring performance.

[0117] High integration:

[0118] The N32G43 microcontroller module typically features high integration, incorporating multiple functional modules such as a built-in analog-to-digital converter.
