Description

Technical Field

[0001] This utility model relates to a hypoxia-inducing training device, belonging to the field of biomedical engineering technology. Background Technology

[0002] Hypoxia-induced training has received widespread attention in sports science and biomedicine in recent years. Studies have shown that hypoxia has a significant stimulating effect on human metabolism, cardiopulmonary function, and erythropoiesis, effectively improving the body's oxygen utilization efficiency and exercise endurance. This mechanism has been widely applied in athletes' high-altitude training, cardiopulmonary rehabilitation, and the treatment of some diseases.

[0003] Current traditional hypoxia-inducing training equipment, such as the animal limb ischemia adaptation training device disclosed in prior patent application CN207679484U, uses pressure sensors to detect the pressure of inflatable airbags and a control device to regulate the pressure of the airbags on the animal's limbs to create a hypoxic environment. However, it cannot perform digital analysis of the data under hypoxic conditions. In addition, hypoxia induction can also be achieved through a sealed chamber, where a person enters the chamber and the hypoxia activates and stabilizes hypoxia-inducible factors. This method is rudimentary and lacks safety guarantees; another method is a breathing helmet, which, compared to a sealed chamber, seals the head and reduces the structural volume, but safety is still not guaranteed, and it requires professional assistance and is cumbersome to operate. Furthermore, traditional training equipment often uses a separate design for blood oxygen detection, which is inconvenient to install and carry. Moreover, the detection method is often based on infrared light, a single light source, which cannot guarantee data accuracy.

[0004] Therefore, it is necessary to design a new type of hypoxia induction training device that can perform hypoxia induction training in a relatively safe and operable local area without the need for professional assistance. Furthermore, it should use multiple detection light sources to collect blood oxygen data, and the blood oxygen detection module should have a high degree of integration, occupy little space, and be easy to carry with the training device. This would meet the requirements for convenience, safety, and accuracy in hypoxia induction training. Utility Model Content

[0018] The data output module is a display screen or a voice module, used to relay the data detected by the blood oxygen detection module.

[0019] The training module includes:

[0020] An armband is used to put a strap over a patient's arm;

[0021] An air pump, connected to the arm cuff via an air tube, is used to inflate the arm cuff.

[0022] The training module also includes a housing and a control circuit board and a solenoid valve installed inside the housing. The solenoid valve and the air pump are both connected to the control circuit board.

[0023] The housing is also provided with an air hole, and the two ends of the solenoid valve are respectively connected to the air pump and the air hole, and the air hole is connected to the air tube of the arm belt.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figure 1-7 As shown, the present invention provides a hypoxia-inducing training device, comprising:

[0035] Training module for patient hypoxia induction training;

[0036] Blood oxygen detection module 2 is used to detect the patient's blood oxygen concentration value;

[0037] The data output module is used to output the blood oxygen concentration value detected by the blood oxygen detection module 2.

[0038] The training module includes a training device 1 and an armband 13. The training device 1 has air vents 3, and an air tube 131 extending from the armband 13 is inserted into the air vents 3. The armband 13 is used to fit around the patient's arm. The training device 1 includes a housing 11 protecting the internal control circuit board 8, and a power supply 82, a solenoid valve 83, and an air pump 81 disposed inside the housing 11. The air pump 81 is used to inflate the armband 13. The two ends of the solenoid valve 83 are respectively connected to the air pump 81 and the air vents 3. The air from the air pump 81 is transferred to the air vents 3 and then enters the air tube 131 to complete the gas delivery operation. The power supply 82, the solenoid valve 83, and the air pump 81 are all mounted on the control circuit board 8 inside the housing 11. The solenoid valve 83 is located on both sides of the power supply 82. The air pump 81 is mounted on the bottom of the control circuit board 8. The air vents 3 are located on both sides of the training device 1. By adopting an integrated design, internal components such as power supply 82, solenoid valve 83, and air pump 81 are compactly mounted on control circuit board 8, making the device lightweight and portable, suitable for various scenarios such as gyms, rehabilitation centers, or home use.

[0039] The two ends of the solenoid valve 83 are connected to the air pump 81 and the air port 3, respectively, to achieve precise control of airflow. This ensures that the equipment can adjust air pressure and flow rate according to training needs, improving the accuracy and effectiveness of hypoxic environment simulation. The solenoid valve 83 regulates the opening and closing of airflow by controlling electrical signals, giving the equipment automated air path adjustment capabilities, reducing the complexity of manual operation for users, and making it more convenient to use. Moreover, the cooperation of the air pump 81 enables the solenoid valve 83 to manage air pressure more efficiently, avoid unnecessary airflow leakage, improve the energy utilization efficiency of the equipment, and extend the battery life of the power supply 82.

[0040] The data output module is a display screen 7, which is used to relay the data detected by the blood oxygen detection module 2. The outer surface of the housing 11 is also provided with a display screen 7.

[0041] The display screen 7 is connected to the control circuit board 8 via wires or pin headers and terminal blocks, facilitating its assembly, disassembly, and maintenance. If the display screen 7 malfunctions, only the display screen 7 or its corresponding connection structure needs to be replaced, eliminating the need for complete equipment replacement and reducing maintenance costs. This also avoids complex internal wiring, reducing design complexity and enhancing overall structural reliability. Furthermore, it ensures stable transmission of data and electrical signals between the control circuit board 8 and the display screen 7, providing real-time display of training data and ensuring accurate information feedback for the user.

[0042] The top of the control circuit board 8 is also provided with a charging port 10, and the top of the corresponding housing 11 is provided with a charging through hole 101, so that users can quickly find the charging interface and avoid damage to the device or inconvenience of use due to inconvenient plugging and unplugging. In addition, the compact design of the charging port 10 and the top of the control circuit board 8 makes full use of the internal space of the device, maintaining a reasonable internal layout while avoiding wasted space, making the device more compact and exquisite.

[0043] A switch 9 is also provided on the top of the control circuit board 8, and a corresponding through hole for the switch 9 is provided on the top of the housing 11, allowing users to easily operate the device by switching it on and off, making it more intuitive and convenient to use. Furthermore, mounting the switch 9 on the top of the control circuit board 8, combined with the through hole design of the housing 11, does not occupy extra space and avoids the vulnerability caused by an externally protruding switch 9, thus optimizing the overall structure of the device. In addition, the switch 9 is designed as a sliding switch, controlling the start and stop via a sliding slider, preventing accidental contact and avoiding malfunctions due to unforeseen circumstances, thus enhancing safety.

[0044] The back of the housing 11 is provided with an anti-static and anti-slip pad 111, which effectively increases the friction between the equipment and the contact surface. This ensures the stability of the equipment and prevents it from sliding or tipping over, regardless of whether it is used on a smooth or inclined surface. Simultaneously, the use of anti-static materials effectively reduces the interference of static electricity on the internal electronic components of the equipment, ensuring the stability and safety of the equipment's operation, and is particularly suitable for protecting precision instruments.

[0045] The surface of the housing 11 is provided with a start / stop button 4, a training button 5, and a detection button 6, which are used to facilitate the operation of the training device 1 during hypoxia-induced training.

[0046] The blood oxygen detection module 2 is installed inside the housing 11, specifically located inside the housing 11 near the upper left and upper right corners of the control circuit board 8. Correspondingly, a detection window 122 is provided on the wall of the housing 11 near the blood oxygen detection module 2, which is used to contact the detection area to collect detection data.

[0047] The upper left and upper right corners of the housing 11 are provided with grooves 12, and the blood oxygen detection module 2 is installed in the grooves 12. This effectively avoids external impacts, protects the module's sensors and circuitry, and improves the durability and reliability of the device. Furthermore, the grooves 12 provide a stable mounting position for the detection module, preventing it from loosening or shifting due to vibration or collisions during device movement or use, thus improving operational stability. At the same time, the groove design embeds the detection module inside the housing 11, saving internal space and preventing the module from protruding from the surface of the housing 11, improving the overall compactness and aesthetics of the device.

[0048] The blood oxygen detection module 2 can be an existing detection device, but as an improvement, in this invention, the blood oxygen detection module 2 is a multi-source blood oxygen detection module, including: a detection phototube 23, used to detect the intensity change of the light source after it is scattered or absorbed; a first light-emitting diode 21, used as a light source emitting red light; a second light-emitting diode 22, connected to the control module 25, used as a light source emitting near-infrared light; the control module 25, connected to the detection phototube 23, the first light-emitting diode 21, and the second light-emitting diode 22, and also connected to the control circuit board 8, used to control the start and stop of the detection phototube 23 and the first light-emitting diode 21. An in-situ detection sensor 24, connected to the control module 25, is used to sense the patient's detection position. Through the cooperation of the detection phototube 23 and the light-emitting diodes, physiological indicators such as blood oxygen concentration and heart rate of the finger can be accurately measured. The first light-emitting diode 21 and the second light-emitting diode 22 are used to emit light of different wavelengths respectively, and the detection phototube 23 performs accurate detection based on the changes in the intensity of the collected light, providing high-precision data support. Furthermore, the combination of the photodetector 23 and the light-emitting diode enables the blood oxygen detection module 2 to monitor the finger's status in real time and provide feedback to the display screen 7. Users can check their physical condition at any time, ensuring the safety and effectiveness of training. Additionally, the in-place detection sensor 24 can sense whether the finger is placed on the detection module, ensuring that each training data comes from correct operation. If the finger is incorrectly positioned, the sensor can immediately provide feedback, preventing erroneous data caused by improper operation.

[0049] The detection phototube 23, the first light-emitting diode 21, the second light-emitting diode 22, and the in-situ detection sensor 24 are all integrated into the control module 25. This integrated design concentrates multiple key components (such as the detection phototube 23, the light-emitting diodes, and the in-situ detection sensor 24) on the control module 25, significantly simplifying the system's hardware structure. It reduces complex wiring and external components, making the device more compact, stable, and easier to assemble and maintain. Furthermore, concentrating the detection phototube 23, the red and near-infrared light-emitting diodes, and the in-situ detection sensor 24 within the same module ensures optical alignment and coordinated operation between components, reducing data deviations caused by inaccurate component positioning and improving the accuracy and consistency of measurement data. In addition, the integrated design reduces the space occupied by individual components, making the device more compact. For devices like the hypoxia-induced training instrument that require portability and ease of use, the optimized size makes it more suitable for portability and improves the user experience.

[0050] The first light-emitting diode 21 emits 660nm red light. In blood oxygen saturation measurement, the difference in absorption characteristics between oxyhemoglobin and deoxyhemoglobin in the blood produces a significant response. By using 660nm red light, the concentration of oxyhemoglobin can be effectively detected, allowing the detection phototube 23 to more sensitively capture the light signal, thereby accurately measuring blood oxygen levels and providing higher measurement accuracy. This design reduces errors and interference, ensuring more accurate physiological data. Furthermore, red light can effectively penetrate the skin and be absorbed by oxyhemoglobin in the blood, resulting in good contrast between the reflected light received by the detection phototube 23 and the surrounding environment, thus enhancing signal quality and improving detection performance.

[0051] The second light-emitting diode 22 emits near-infrared light at a wavelength of 940nm. Near-infrared light at 940nm has a strong absorption capacity for deoxygenated hemoglobin. This allows near-infrared light, in conjunction with red light (660nm), to accurately distinguish the ratio of oxyhemoglobin to deoxyhemoglobin when detecting blood oxygen saturation, thereby improving the accuracy of blood oxygen concentration measurement. Furthermore, near-infrared light has strong penetrability, allowing it to penetrate skin and blood vessels for effective detection at deeper blood levels. Combined with 660nm red light, it provides more physiological information, enhancing the multidimensionality and comprehensiveness of the data.

[0052] In actual use, first fix the armband 13 near the armpit, then slide to turn on the switch 9 of the training device 1. Hold the training device 1 with both hands, placing your index or middle finger on the blood oxygen detection module 2 to ensure the module can collect data. Then, based on the real-time data displayed on the screen 7, the patient uses their thumb to operate the start / stop button 4, training button 5, and detection button 6 to complete the hypoxia-induced training. The operating principle is to pre-fix the relative positions of bones, blood vessels, and muscles by increasing the pressure of the armband 13. When the data on the screen 7 reaches the predetermined value, the duty cycle of the pressure control PWM is adjusted to the relative maximum, quickly blocking veins and arteries. This position is maintained, and after judging from the data on the screen 7 that the elastic reaction force of the armband 13 and the muscle tension are in balance and stable, final pressure is applied. The blood vessels are pressed against the bones by the muscles. This method of hypoxia-induced training has the best blocking effect, significantly reduces user discomfort, improves training tolerance, and significantly reduces arm indentations after training.

[0053] By adopting the above technical solution, the hypoxia-inducing training device 1 of this utility model, through the setting of solenoid valve 83, air pump 81, and air vent 3, achieves precise control of airflow, simulates different hypoxia environments, and is suitable for scientific training and rehabilitation assistance. Simultaneously, it is equipped with a blood oxygen detection module 2, which utilizes dual-wavelength technology emitting 660nm red light and 940nm near-infrared light to monitor physiological parameters such as blood oxygen saturation in real time, ensuring accurate and reliable data. Furthermore, the display screen 7 of the data output module can intuitively present the training status. The device's compact and portable structure, the ergonomic design of the armband 13, and its efficient and precise airflow control provide safe and scientific support for hypoxia-inducing training, while significantly improving the user experience.

[0054] 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 protection scope of this invention.
