Description

Technical Field

[0001] This utility model belongs to the field of breathing training equipment, and in particular relates to a portable patient breath-holding training device. Background Technology

[0002] Deep Inspiration Breath Hold (DIBH), an advanced respiratory gating technique, has significant application value in radiotherapy, especially in the treatment of thoracic tumors. The basic principle of this technique requires the patient to take a deep breath and hold it before treatment, using this as their breathing state during therapy. Through this operation, DIBH significantly reduces unnecessary radiation dose and volume to the heart and lungs during radiotherapy, effectively minimizing potential damage to normal tissues. The introduction of DIBH also greatly improves the accuracy of radiotherapy. In conventional radiotherapy, the thoracic tumor target area moves due to the body's respiratory movements, forming a dynamic irradiation target area. This dynamism increases the difficulty and uncertainty of radiotherapy. However, with DIBH, the tumor target area remains relatively stable during breath-holding, transforming this "moving target" into a relatively static target area, making radiotherapy more precise and improving treatment outcomes.

[0003] The DIBH (Diverterless Inhalation and Hemostasis) technique further reduces the radiation dose to the cardiopulmonary region by increasing lung volume, causing the diaphragm to shift downwards, and elevating the thoracic cavity. This effect not only enhances the safety of radiotherapy but also provides good repeatability, ensuring that each treatment achieves the desired irradiation effect. Therefore, in the radiotherapy of thoracic tumors such as lung cancer and breast cancer, the DIBH technique can bring significant benefits to more patients compared to radiotherapy under free breathing conditions. However, in practical application, the breath-holding technique requires a high level of patient cooperation. Before radiotherapy, doctors need to observe and guide patients one-on-one in breath-holding training. This training method is not only time-consuming and laborious but also inefficient. Patients often cannot meet the requirements of radiotherapy in terms of the rhythm, depth, and duration of breath-holding, resulting in longer radiotherapy times, lower efficiency, and compromised biological effects. This affects the treatment outcome and the number of patients that can be treated daily by the linear accelerator. Utility Model Content

[0007] The guidance display mechanism includes a display and a speaker;

[0008] The signal processing mechanism is electrically connected to the tension sensor and the pressure sensor respectively, and is used to receive the status signals of the tension sensor and the pressure sensor; the signal processing mechanism is electrically connected to the display and the speaker respectively, and is used to control the playback content of the display and the speaker.

[0009] Optionally, the fixing strap is an elastic fixing strap; the tension sensor is fixedly connected in parallel to the inner side of the fixing strap.

[0010] Optionally, there are two fixing straps, and each of the two fixing straps is fixedly connected to a clamping and positioning member at the end away from the connecting buckle; each of the two clamping and positioning members has an installation groove at the end away from the fixing strap; the two installation grooves are respectively clamped and fixed to the end of the tension sensor; the two fixing straps and the tension sensor together form a ring structure.

[0018] As described above, the portable patient breath-holding training device of this utility model has at least the following beneficial effects:

[0019] This invention breaks down the breath-holding training device into a sensing and monitoring mechanism, a guidance and display mechanism, and a signal processing mechanism. This achieves high-precision monitoring and intuitive guidance during the breath-holding training process, improving training effectiveness and user experience. The addition of tension and pressure sensors within the sensing and monitoring mechanism allows the device to comprehensively and accurately capture physiological changes during the patient's breathing process. The tension sensor, secured by a strap, fits tightly against the patient's examination site, enabling real-time monitoring of subtle contour changes caused by breathing, providing data for assessing breathing patterns. Simultaneously, the addition of a pressure sensor allows the device to measure the expansion resistance of the strap on the chest and abdominal cavities during breathing, facilitating the assessment of the patient's breathing force, depth, and potential respiratory obstruction. The display within the guidance and display mechanism plays real-time video feeds from the sensing and monitoring mechanism. The system collects status changes, visually displaying the dynamic responses of different examination sites during patient breathing. This visual feedback mechanism not only facilitates patient self-observation and adjustment of breathing patterns but also enhances the interactivity and participation of the training process. The speaker provides sound reminders and guidance, effectively guiding patients to train according to specific breathing frequencies and depths through preset rhythms or instructions, further enhancing the scientific rigor and effectiveness of the training. The signal processing mechanism, as the central hub of the entire system, receives and processes status signals from the stretch and pressure sensors. Through processing, this raw data is transformed into easily understandable and operable playback content, such as graphical breathing curves and voice prompts, simplifying the user experience and making the training process more intelligent and efficient.

[0020] This invention simplifies the fixing process of the tension sensor by adding a clamping and positioning component to the fixing strap, ensuring the stability and accuracy of the sensor during training. The clamping and positioning component firmly holds the tension sensor, preventing displacement or loosening during the patient's breathing, thus ensuring the continuity and reliability of the monitoring data. An arc-shaped mounting plate is fitted on the side of the tension sensor closest to the patient's body, facilitating the installation of the pressure sensor. The arc-shaped mounting plate increases the stability of the installation, allowing the pressure sensor to more accurately monitor the expansion of the chest and abdominal cavities during the patient's breathing. A detachable pad on the side of the mounting plate closest to the patient's body increases the fit and evenly distributes the compressive force on the pressure sensor, avoiding inaccurate monitoring data due to excessive local pressure, ensuring that the pressure sensor can accurately and stably monitor the patient's respiratory status. Both the tension and pressure sensors in this invention are designed to be detachable. This design facilitates storage and maintenance after training, allowing users to disassemble the sensors as needed and store them in a dedicated storage box, avoiding the risk of damage or loss due to prolonged exposure.

[0021] This invention improves the flexibility and adaptability of the fixation strap by adding connecting buckles. Patients can adjust the connection length of the fixation strap under the guidance of a doctor to adapt to different body types and training needs, avoiding the need for patients to readjust the connection length of the fixation strap during training. After adjustment, the strap is fixed by inserting or hooking the connecting buckles for easy wearing, ensuring the accuracy of data during training and providing doctors with more reliable assessment basis, thereby helping to develop more scientific training plans and improve training efficiency.

[0032] Please see Figures 1 to 7 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0033] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0034] Please see Figures 1 to 7This invention provides a portable patient breath-holding training device, comprising a sensing and monitoring mechanism, a guidance and display mechanism, and a signal processing mechanism 7. The sensing and monitoring mechanism includes a tension sensor 1, a pressure sensor 2, and a fixing strap 3. The tension sensor 1 is fixedly connected to the patient's examination site via the fixing strap 3 to monitor the expansion amplitude of the patient's thoracic and abdominal cavities. The tension sensor 1 is a flexible capacitive strain sensor; the expansion of the thoracic and abdominal cavities causes a change in the distance between the stretchable electrodes, resulting in a change in capacitance, which converts the change in the patient's respiratory profile into an electrical signal. The pressure sensor 2 is fixedly connected inside the tension sensor 1 to monitor the patient's breath-holding. The pressure sensor 2 is a piezoresistive pressure sensor that converts the expansion resistance of the fixation strap 3 against the patient's chest and abdominal cavity during breathing into an electrical signal. The fixation strap 3 is equipped with a connecting buckle 301 for adjusting its tightness. The guidance display mechanism includes a display 5 and a speaker 6. The display 5 shows the status changes of the sensing and monitoring mechanisms fixed at different examination sites during the patient's breathing, as well as the overall status changes of the patient's breath-holding. The speaker 6 provides guidance on the patient's breathing rhythm. The signal processing mechanism 7 can be set separately or integrated into the display 5. This system enables data monitoring and storage via a wireless network, recording and uploading the entire patient training process. Medical staff can evaluate and record the quality of the patient's breathing training by using the uploaded data. The signal processing mechanism 7 is electrically connected to the tension sensor 1 and the pressure sensor 2, respectively, to receive the status signals of the tension sensor 1 and the pressure sensor 2. The signal processing mechanism 7 is also electrically connected to the display 5 and the speaker 6, respectively, to control the playback content of the display 5 and the speaker 6. The signal processing mechanism 7 can be a PLC controller, a microcontroller, or a computer. This application breaks down the breath-holding training device into a sensing and monitoring mechanism, a guidance and display mechanism, and a signal processing mechanism. 7; High-precision monitoring and intuitive guidance of the breath-holding training process have been achieved, improving training effectiveness and user experience; The addition of tension sensor 1 and pressure sensor 2 in the sensor monitoring mechanism enables the device to comprehensively and accurately capture the physiological changes of the patient during the breathing process. The tension sensor 1 is fixed in close contact with the patient's examination site through the fixation strap 3, and can monitor the subtle changes in the contour caused by breathing in real time, providing data for assessing the breathing pattern. At the same time, the addition of pressure sensor 2 enables the device to measure the expansion resistance of the fixation strap 3 to the chest and abdominal cavity when the patient breathes, which is convenient for judging the patient's breathing strength, depth and potential breathing obstacles.The display screen 5 within the guidance display mechanism plays real-time updates of the status changes collected by the sensor monitoring mechanism, intuitively showing the dynamic reactions of different examination sites during the patient's breathing. This visual feedback mechanism not only facilitates self-observation and adjustment of breathing patterns by the patient but also enhances the interactivity and participation of the training process. The speaker 6 provides sound reminders and guidance, effectively guiding the patient to train according to specific breathing frequencies and depths through preset rhythms or instructions, further enhancing the scientific rigor and effectiveness of the training. The signal processing mechanism 7, as the central hub of the entire system, receives and processes status signals from the tension sensor 1 and pressure sensor 2. Through processing, this raw data is transformed into easily understandable and operable playback content, such as graphical breathing curves and voice prompts, simplifying the user experience and making the training process more intelligent and efficient.

[0035] In this embodiment, please refer to Figures 4 to 7 The fixing strap 3 can be an elastic fixing strap; the tension sensor 1 is fixedly connected in parallel to the inner side of the fixing strap 3 (both ends of the tension sensor 1 can be fixed to the inner side of the fixing strap 3 by Velcro); the fixing strap 3 can also be two straps, and each of the two fixing straps 3 has a clamping positioning member 302 fixedly connected to its end away from the connecting buckle 301; each of the two clamping positioning members 302 has a mounting groove (e.g., ...) at its end away from the fixing strap 3. Figure 4 As shown, the mounting groove includes a circular mounting groove body and a strip-shaped mounting groove sub-body at one end away from the fixing strap, which facilitates the engagement and locking of the columnar end of the tension sensor 1; the two mounting grooves are respectively engaged and fixed to the ends of the tension sensor 1; the two fixing straps 3 and the tension sensor 1 form a ring structure; an arc-shaped mounting plate 4 is fixed to the side of the tension sensor 1 closest to the patient's body (e.g., Figure 5As shown, a mounting plate bracket is fixedly connected to the outer side of the mounting plate 4, and the mounting plate 4 is sleeved on the outer side of the tension sensor 1 through the mounting plate bracket; the mounting plate 4 has mounting holes for mounting and fixing the pressure sensor 2; a pad 401 is detachably connected to the side of the mounting plate 4 closest to the patient's body; the pad 401 has a groove on the side close to the mounting plate 4 that cooperates with the mounting plate 4, and the other side is bent to fit against the patient's body (the pad 401 has various styles for the patient to choose from, ensuring that the side of the pad 401 away from the mounting plate 4 fits against the patient's examination area, thereby ensuring that the pressure sensor 2 is subjected to uniform force). This application simplifies the fixing process of the tension sensor 1 by adding a clamping and positioning component 302 to the fixing strap 3, ensuring the stability and accuracy of the sensor during training. The clamping and positioning component 302 can firmly clamp the tension sensor 1, preventing it from shifting or loosening during the patient's breathing, thereby ensuring the continuity of monitoring data. The system ensures continuity and reliability. An arc-shaped mounting plate 4 is fitted onto the side of the tension sensor 1 closest to the patient's body, facilitating the installation of the pressure sensor 2. The arc-shaped mounting plate 4 increases the stability of the installation, allowing the pressure sensor 2 to more accurately monitor the expansion of the chest and abdominal cavities during patient respiration. A detachable pad 401 on the side of the mounting plate 4 closest to the patient's body increases the fit and evenly distributes the compressive force on the pressure sensor 2, preventing inaccurate monitoring data due to excessive local pressure. This ensures that the pressure sensor 2 can accurately and stably monitor the patient's respiratory status. Both the tension sensor 1 and the pressure sensor 2 in this invention are designed to be detachable. This design facilitates storage and maintenance after training, allowing users to disassemble the sensors as needed and store them in a dedicated storage box, avoiding the risk of damage or loss due to prolonged exposure.

[0036] In this embodiment, the connecting end of the connecting buckle 301 and the fixing strap 3 can be a U-shaped connector, and the connection position with the fixing strap 3 can be adjusted through the U-shaped connector. The other end of the connecting buckle 301 is a U-shaped hook. The connecting buckle 301 can also be a connecting buckle including a female buckle and a female buckle of the fixing strap 3, which are used together. By adding the connecting buckle 301 to the fixing strap 3, this application improves the flexibility and adaptability of the fixing strap 3. Under the guidance of a doctor, the patient can adjust the connection length of the fixing strap 3 to adapt to different body types and training needs, avoiding the situation where the patient needs to readjust the connection length of the fixing strap 3 during training. After adjustment, the connecting buckle 301 can be inserted and fixed or hooked for easy wearing, ensuring the accuracy of data during training, providing doctors with more reliable evaluation basis, thereby helping to formulate a more scientific training plan and improve training efficiency.

[0037] In this embodiment, there are multiple sets of sensor monitoring mechanisms, which are fixedly connected to the patient's chest, abdomen, and chest-abdomen area respectively. The data from the multiple sets of sensor monitoring mechanisms are processed by the signal processing mechanism 7 and displayed on the display 5 to show the changes in the patient's chest, abdomen, and chest-abdomen area. During breath-holding, if the patient experiences a transfer of air from the chest to the abdomen or vice versa, the system can promptly alert the patient. The patient can adjust their breathing state in real time according to the changes in the chest and abdominal cavities and correctly complete the breathing training.

[0038] In summary, this utility model overcomes the various shortcomings of the prior art.

[0039] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
