Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a respiratory exercise feedback system. Background Art

[0002] In modern respiratory diseases, patients need to perform respiratory exercises during the rehabilitation process. At present, the respiratory exercises are mainly carried out under the guidance of doctors. On the one hand, this increases the workload of doctors and delays their other work. On the other hand, doctors cannot monitor the patients' respiratory exercises throughout the process, and patients cannot know the effects of their own respiratory exercises, which easily leads to poor respiratory exercise effects between doctors and patients and then slower recovery.

[0003] Regarding the above technical problems, there are some medical device respiratory trainers at present. These respiratory trainers often work based on the principle of resistance respiratory training. However, breathing is an action that involves most of the upper body muscle groups, and the existing resistance respiratory exercise devices usually can only target pursed-lip breathing rehabilitation exercises and cannot take into account the respiratory training of stoma surgery patients.

[0004] For the above reasons, during the respiratory exercise process of stoma surgery patients, it is necessary to control the upper body, especially the chest, to make respiratory exercise movements. For example, the human respiratory state monitoring system and method based on flexible sensing and deep learning disclosed in the publication number CN111671426A measures electrical signals through flexible sensors and improves the monitoring accuracy through deep learning and self-training methods. It only focuses on the monitoring process of respiratory exercises but does not pay attention to the feedback during the exercise process, and cannot more intuitively and effectively guide patients to perform respiratory exercises. Furthermore, there is no device that can meet the requirement of performing respiratory feedback exercises based on deep learning. In view of this, in-depth research on the above problems has led to the generation of this case. Summary of the Invention

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figures 1-9 , the present invention provides an implementation solution: Resistance exercise equipment is common in modern breathing exercise equipment. Such equipment is often suitable for constricted orifice training. For patients who have undergone laryngeal stoma surgery, this exercise equipment cannot meet the usage requirements. Moreover, further, current breathing exercise equipment often only has a monitoring function, and patients cannot obtain effective feedback during the exercise process.

[0041] In view of the above technical problems, the present application discloses a breathing exercise feedback system, which is divided into a monitoring unit, a cloud platform, and a feedback processing unit. The monitoring unit is attached to the patient's respiratory muscle group through induction electrodes, senses the patient's muscle group movements and converts them into electrical signals, transmits them to the cloud platform for processing, and sends the processing results to the feedback processing unit. The feedback processing unit makes feedback adjustments to the patient's breathing training, constituting a complete training system.

[0042] Among them, the monitoring unit includes a host computer, a microcontroller, and no less than 4 groups of independent SEMG sensors; the SEMG sensors are attached to the upper body respiratory muscle group of the human body and are used to convert human breathing data into analog signals for output; the microcontroller is connected to the SEMG sensors through analog-to-digital conversion, converts the analog signals of human breathing data into digital signals, and transmits them to the host computer; the host computer receives the digital signals from the microcontroller and sends them to the cloud server;

[0043] Specifically, the SEMG sensor detects the movements of the human respiratory muscle groups and converts them into analog signals. The analog signals are converted into electrical signals through analog-to-digital conversion and transmitted to the microcontroller. The microcontroller transmits data to the host computer, which is specifically an electronic integration terminal. The host computer packs and sends the digital signal data of the microcontroller to the cloud server. At the same time, the host computer also has a display panel, which on the one hand displays the data of respiratory training, and on the other hand provides a touch screen operation panel. The training plan of the patient and some data of the patient (basic information such as height, weight, gender, age, etc. and the patient's condition data) are input from the host computer, and the host computer transmits these data to the cloud server;

[0044] The cloud server receives and processes the digital signals sent by the host computer, monitors, analyzes, and feedback-processes the human respiratory data using a deep learning network model, and then transmits the processed data results to the host computer;

[0045] Specifically, the cloud server receives the digital signals from the host computer and processes the data using a deep learning network model. The specific deep learning network model unit consists of an embedding layer network unit, a bidirectional GRU layer network unit, an attention layer network unit, a fully connected layer unit, a Softmax unit, etc. After using multiple learning units for monitoring and analysis, while strengthening the accuracy of monitoring data in a deep learning manner, taking advantage of the data of the cloud server, targeted training measures are analyzed based on the monitoring data (such as analyzing that the breathing force and frequency do not reach the breathing force and frequency, and then feedbacking a greater breathing force and a faster breathing frequency to the patient);

[0046] According to the attached instructions Figure 1 It can be seen that in order to visually feedback the exercise measures to the user, a feedback processing unit is also set up, which consists of a secondary processor, a feedback regulator, and a feedback limiter. Among them, the secondary processor and the feedback regulator are both installed based on the host computer, while the feedback limiter is installed independently, and the feedback limiter is connected to the feedback regulator through a data cable;

[0047] Specifically, the processed data of the cloud server is sent to the host computer, and the host computer transmits it to the secondary processor. The secondary processor converts the digital signal into an analog signal through digital-to-analog conversion and sends it to the feedback regulator. The feedback regulator receives the analog signal of the secondary processor, amplifies it, and transmits it to the feedback limiter;

[0048] The device that visually provides feedback to the patient is the feedback limiter, which makes corresponding actions according to the analog signal of the feedback processor, indicating the opening position and opening frequency of the patient's breathing chest cavity.

[0049] Furthermore, according to the attached instructions Figures 2-9It can be seen that the feedback limiter is composed of an independent frame 1, an actuator 4, a follower contact plate 5, a feedback display component and a connected flow detection component 7; wherein the independent frame 1 is an external structure with a supporting function, the actuator 4 is used to execute the feedback result of the feedback analog signal, the follower contact plate 5 contacts the human body and moves according to the chest movement of the human body, and is linked with the actuator 4, and the exercise effect is fed back to the patient through the comparison of the actuator 4, and the connected flow detection component 7 is used as a second independent detection means to assist in detecting the gas flow during the breathing exercise;

[0050] According to the instruction manual Figures 2-4 It can be seen that the above-mentioned independent frame 1 is a rectangular structure frame, and at least one pair of support plates 2 are arranged on the independent frame 1. The support plates 2 and the independent frame 1 are connected in a split manner. The execution sleeve 3 and the support plate 2, including the execution assembly 4 in the execution sleeve 3, can be replaced through the threaded structure, thereby improving the flexibility of application and the replaceability of accessories.

[0051] Furthermore, a pair of height adjusters 6 are provided on both sides of the independent frame 1, and the height of the actuator 4 can be adjusted by the height adjusters 6 to match the use of people of different heights. The height adjuster 6 consists of a slide 61 opened on one side of the independent frame 1, a sliding block 62 assembled on the slide 61, and an adjustment support rod 63 movably installed with the slide 61 and threadedly engaged with the sliding block 62. The adjustment support rod 63 can be threadedly engaged with the sliding block 62 by rotating the adjustment support rod 63, and then the sliding block 62 can be slid in the slide 61, so that the sliding block 62 extends from the independent frame 1, and the sliding block 62 is used to contact the bed surface or the seat armrest to lift the height of the independent frame 1 to a height suitable for the user.

[0052] According to the instruction manual Figures 2-6 It can be seen that the end of the actuator 4 is connected to a follower contact plate 5 that contacts the human chest. The follower contact plate 5 is a plate with a rectangular structure. A thin cotton layer 51 is provided on one side of the follower contact plate 5 to improve comfort and minimize sedimentation and other problems caused by the thick cotton layer. Specifically, the thin cotton layer 51 can be replaced with a more suitable material such as a polyurethane layer. A threaded adjustment sleeve 52 is provided on the other side of the follower contact plate 5 and is movably connected to the end of the indicator rod 42 for adjusting the initial position of the follower contact plate 5 so that it can fully contact the human chest.

[0053] According to the instruction manual Figures 5-7It can be seen that the above-mentioned execution component 4 includes a closed sliding sleeve 41, which is coaxially assembled on the execution sleeve 3. One end of the closed sliding sleeve 41 is provided with an indicating rod 42 penetrating through it, and the other end of the closed sliding sleeve 41 is provided with a control air pump 43. The control air pump 43 is communicated with the inner cavity of the closed sliding sleeve 41. The end of the indicating rod 42 is fixedly connected with a sliding piston 44. A return spring 45 is also arranged between the sliding piston 44 and one side of the control air pump 43. The sliding piston 44 matches the shape of the radial cross-section of the inner cavity of the closed sliding sleeve 41, and the head end of the indicating rod 42 is connected with the follower contact plate 5.

[0054] In the specific implementation process, the closed sliding sleeve 41 is fixedly installed by being assembled in the execution sleeve 3. The closed sliding sleeve 41, the sliding piston 44 and the control air pump 43 together constitute a pneumatic control system. According to the expansion and contraction of the human chest cavity, the indicating rod 42 is pushed to drive the sliding piston 44 to move. The control air pump 43 is connected to the feedback regulator. The control air pump 43 inflates and exhausts air into the closed sliding sleeve 41, which can cause a change in the air pressure on one side of the sliding piston 44. During the process of the patient pushing the follower contact plate 5 to move with the indicating rod 42, the change in air pressure changes the reaction force between the follower contact plate 5 and the human body, enabling the patient to intuitively feel the movement change of the chest during breathing.

[0055] Furthermore, the above-mentioned execution component 4 further includes an arc-shaped power connection groove. An arc-shaped power connection groove is opened on one side of the closed sliding sleeve 41, and a power connection sliding plate 46 is connected to the arc-shaped power connection groove. A power connection block 47 is arranged on one side of the sliding piston 44 and contacts the power connection sliding plate 46;

[0056] In the specific implementation process, in order to more intuitively reflect the expansion and contraction process of the patient's chest cavity, in addition to displaying the breathing data on the upper computer, by directly converting the breathing action of the chest cavity into a control signal and displaying it. Specifically, during the movement process of the chest cavity, on the one hand, the power connection sliding plate 46 is installed on the arc-shaped power connection groove to ensure the sealing performance of the closed sliding sleeve 41. On the other hand, the power connection sliding plate 46 uses contact resistance. When the sliding piston 44 moves with the chest cavity, it drives the power connection block 47 to move, so that the power connection block 47 contacts any position of the power connection sliding plate 46, changing the resistance value of the circuit composed of the power connection sliding plate 46, the power connection block 47 and the power supply, and further changing the magnitude of the current, realizing the function of digitalizing the expansion and contraction movement of the chest cavity;

[0057] Furthermore, an indicator board 8 is provided on the above-mentioned actuating sleeve 3. A rhythm light bar 81 is provided on the indicator board 8. The light of the rhythm light bar 81 transitions from cold light to warm light. Through the fixed installation of the indicator board 8 and the actuating sleeve 3, the indicator board 8 is fixed. The power connection slide plate 46 and the power connection block 47 form a position indicator. As can be seen from the above, when the power connection block 47 is in different positions on the power connection slide plate 46, the current of this circuit is different. The microcontroller converts the strength of this current signal into the lighting length of the rhythm light bar 81, and the light of the rhythm light bar 81 transitions from cold light to warm light. Thus, the degree of chest cavity expansion and contraction can be represented more vividly. Naturally, the change frequency of the magnitude of the control current serves as a symbol of the chest cavity expansion and contraction frequency. Furthermore, according to the interval of the change in the magnitude of the current, a minimum turn-on current is set for the rhythm light bar 81, and the expansion and contraction frequency of the chest cavity can be intuitively displayed.

[0058] Furthermore, an indicator light bar 82 is provided on one side corresponding to the rhythm light bar 81. The indicator light bar 82 is arranged in parallel with the rhythm light bar 81. The lighting length and flashing frequency of the indicator light bar 82 are controlled by a feedback regulator. In this way, according to the result of the feedback data, the lighting length and flashing frequency of the indicator light bar 82 are controlled. With a distinct contrast formed between the rhythm light bar 81 and the indicator light bar 82, it can assist in guiding breathing exercises.

[0059] Furthermore, a heart rate measurement electrode is also provided on the SEMG sensor. A liquid crystal display 83 is provided on the indicator board 8 corresponding to the heart rate measurement electrode. The liquid crystal display 83 can display the heart rate, facilitating the patient to observe their own heart rate and avoid excessive heart rate and overexercising.

[0060] According to the attached instructions Figures 8-9 As can be seen, a connecting and communicating flow detection component 7 is provided on the above-mentioned feedback limiter and is connected to the stoma tube of the patient. The connecting and communicating flow detection component 7 includes an intake pipe 71. One end of the intake pipe 71 is fixed to the independent frame 1 through a bracket. A connector 72 is provided at one end of the intake pipe 71. The connector 72 is a cavity shell with a truncated conical structure. A detection through pipe 73 is provided at the other end of the intake pipe 71. The detection through pipe 73 is communicated with the intake pipe 71. A rotating fan blade 74 is assembled in the detection through pipe 73. The number of the rotating fan blades 74 is at least three groups and is arranged staggeredly. A micro encoder 75 is connected to the central axis of the rotating fan blade 74;

[0061] In the specific implementation process, the connected flow detection component 7 is connected to the stoma tube of the patient, providing a detection device for the auxiliary breathing volume without resistance for stoma patients. Specifically, the plug connector 72 at the end of the intake pipe 71 is inserted into the orifice of the stoma tube. When the patient breathes, the stoma tube, the intake pipe 71, and the detection through-tube 73 form a two-way detection path. When the inhaled or exhaled air flows through the above detection path, it generates a force on the rotating vane in the detection through-tube 73, causing the rotating vane to rotate. Then, the rotating vane drives the central shaft to rotate. Through the gear set, the micro encoder 75 is linked, and the micro encoder 75 converts the rotation data into the data of the breathing air volume, so as to know whether the patient inhales enough air or the exhaust is smooth during the exercise. Compared with the resistance type structure, this training structure does not have the problem of completely blocking the patient's breathing path.

[0062] It should be noted that the connected flow detection component 7 can also be used in the way of constriction training. Just install a mouthpiece device with a conversion head shape on one side of the plug connector 72, and it can be used normally. Combined with the above feedback training, its effect is also better than that of ordinary resistance type breathing training devices.

[0063] Embodiment 1:

[0064] The working principle of the feedback unit of this application is as follows: After the SEMG sensor transmits the data to the cloud server through the host computer, the cloud server analyzes the breathing monitoring data, and the analyzed feedback training method is sent to the host computer. The host computer further sends the data to the secondary processor. The secondary processor disassembles the digital signal and converts it into an analog signal corresponding to different action mechanisms. The analog signal is amplified by the feedback regulator and distributed to each action mechanism of the feedback limiter to achieve feedback processing;

[0065] Specifically, the feedback limiter is supported by an adjustable-height independent frame 1 and integrates at least two groups of execution components 4. When the execution components 4 are used, they can correspond to the patient's chest. Through the control signal given by the feedback regulator, the air pump 43 is controlled to change the air pressure on one side of the movable piston in the closed sliding sleeve 41. According to the feedback result, the frequency and magnitude of the change are controlled, so that the sliding piston 44 gives a reaction force to the patient through the indicating rod 42. The patient adjusts his own breathing with this feedback effect, so that the force exerted by the sliding piston 44 on himself is smaller or within the imperceptible range. Then, the size and frequency of the breathing action are intuitively indicated through the circuit formed by the power-on slide plate 46 and the power-on block 47. When the patient's breathing rhythm is chaotic or for other reasons, resulting in a change in the breathing frequency, the breathing exercise can be corrected by the inconsistent flashing frequency and flashing length of the rhythm light bar 81 and the inconsistent feedback force.

[0066] Embodiment 2:

[0067] The present application also discloses an application method of the above-mentioned respiratory exercise feedback system, which specifically includes the following steps;

[0068] Step 1: The exerciser attaches the SEMG sensor patch corresponding to the muscle group for respiratory exercise to the body, and adjusts the height of the feedback limiter and the position of the follower contact plate to fit their own chest. Then, turn on the upper computer, input their own basic data and medical record data. The cloud server selects an exercise plan according to the data and sends it to the upper computer, and the user selects the exercise plan to start respiratory exercise;

[0069] Step 2: The respiratory data during the respiratory exercise is transmitted to the microcontroller through the SEMG sensor, and after analog-to-digital conversion, it is transmitted to the upper computer, and then transmitted from the upper computer to the cloud server. After parsing the data according to the deep learning network model, the cloud server formulates feedback data and sends it to the upper computer. The upper computer gives a control command to the feedback limiter through the secondary processor and the feedback regulator;

[0070] Step 3: According to the feedback data, control the air pump to adjust the pressure change on one side of the closed sliding sleeve to make it conform to the respiratory intensity and respiratory frequency in the feedback data. The user adjusts their own respiratory intensity and frequency according to the force feedback;

[0071] Step 4: According to the feedback data, the indicator light bar makes a flashing length and flashing frequency that conform to the feedback data. The patient displays their own respiratory intensity and respiratory frequency through the rhythm of the light bar by the expansion and contraction of the chest cavity. By comparing the two, the user gets visual feedback, and then adjusts their own respiratory frequency and respiratory intensity;

[0072] Step 5: Use the liquid crystal display to display the patient's heart rate, and connect the connected flow detection component to the patient's stoma tube to detect the exhaled and inhaled air flow during the patient's respiratory exercise. Connect the liquid crystal display to the micro encoder to also display the respiratory air volume data.

[0073] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
