Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an intelligent vest-type respiratory rehabilitation training device. Background Art

[0002] The incidence of chronic diseases such as COPD is rising year by year. Pneumonia and chronic respiratory failure are common complications and causes of death in stroke patients. Effective respiratory function training is of great significance to improving patients' lung function, enhancing respiratory muscle strength, promoting lung expansion, and reducing the incidence of complications. Therefore, respiratory function training has attracted much attention in recent years. The industry is equipped with professional cardiopulmonary rehabilitation therapists who are responsible for postoperative cardiopulmonary rehabilitation treatment of patients and guide their respiratory function training to prevent complications after surgery and in long-term bedridden patients.

[0003] However, there are many defects in the current breathing training methods. Most of the existing breathing training methods are conventional abdominal breathing, pursed lip breathing, and some breathing exercises. This type of conventional respiratory function training relies on the experience of therapists and patients to carry out exercises, and lacks accurate and objective training standards. Most of the existing breathing trainers are oral ventilation types. Patients can only obtain respiratory ventilation flow rate data by inhaling and blowing air into the lungs to resist ventilation. It is difficult to accurately mobilize the coordinated operation of various respiratory muscles. Given that the human respiratory function is a process of coordinated movement of the muscles and bones of the chest and abdominal organs, it is necessary not only to strengthen the independent working ability of each structure, but also to ensure the coordinated operation of various structures of respiratory function in order to achieve efficient breathing. In addition, the existing breathing trainers cannot monitor and optimize the breathing method, and it is difficult to assist in adjusting the breathing mode. Patients need professional guidance when using ventilation breathing trainers, otherwise they are prone to chest pain, chest tightness, dizziness, nausea and other symptoms due to excessive ventilation, and this ventilation method will increase the risk of airway infection and induce airway hyperresponsiveness or inflammation. Summary of the invention

[0004] In view of this, the purpose of the present invention is to propose an intelligent vest-type respiratory rehabilitation training device, which is provided with an air bag unit made of elastic breathable material and equipped with multiple pressure receptors, ventilation ducts and micro-solenoid valves, a pulmonary function detector composed of a flow sensor, a pressure sensor, a signal conditioning circuit and a microprocessor and connected to a control unit through a data transmission interface, a control unit for analyzing and processing data and adjusting the pressure receptors, a data storage and analysis module that stores and analyzes training data and can be shared remotely, a prompt module that can issue multiple prompts based on the deviation of respiratory parameters, and an intelligent vest-type respiratory rehabilitation training device with an adjustable fastening device and a display screen, thereby solving the problems in the prior art of single type of respiratory training tools, lack of quantitative and objective training standards, inability to accurately mobilize the respiratory muscles to work together, difficulty in monitoring and optimizing breathing methods, and easy to cause excessive ventilation and airway infection risks.

[0029] like Figure 1-6 As shown, an embodiment of the present invention is: an intelligent vest-type respiratory rehabilitation training device, comprising an airbag vest 1:

[0030] The outer protective layer 11 of the airbag vest is made of a wear-resistant, waterproof material with certain protective properties, which plays a role in protecting the internal components. The chest airbag layer 12 and the abdominal airbag layer 13 are arranged in sequence on the inside. The upper chest airbag area 121, the middle chest airbag area 122 and the lower chest airbag area 123 of the chest airbag layer 12 are respectively designed for different chest respiratory muscle functions. The upper chest airbag area 121 focuses on the movement perception and resistance regulation of auxiliary respiratory muscles such as the subclavius ​​and pectoralis minor during breathing; the middle chest airbag area 122 mainly cooperates with the external intercostal muscles and the internal intercostal muscles to accurately perceive the respiratory movements of the intercostal muscles; the lower chest airbag area 123 cooperates with the upper part of the diaphragm and plays an important linkage role in the breathing process. The upper abdominal airbag area 131 of the abdominal airbag layer 13 is closely connected with the lower part of the diaphragm, the middle abdominal airbag area 132 targets the rectus abdominis, and the lower abdominal airbag area 133 works in coordination with the external oblique muscles, internal oblique muscles and transverse abdominal muscles. The chest airbag vest pressure sensor network 14 on the inner side of the chest airbag layer 12 and the abdominal airbag vest pressure sensor network 15 on the inner side of the abdominal airbag layer 13 can sense the pressure changes caused by the movement of the respiratory muscles in real time and transmit the data to the control unit in the central control box 3. The airbag vest lining layer 16 is made of skin-friendly and comfortable materials to reduce friction on the skin. The airbag vest fastening device 17 is located on both sides of the back of the vest, which can adjust the tightness of the vest to ensure the stability of the vest during training.

[0031] Lung function tester 2:

[0032] The main body 21 of the pulmonary function detector is the core shell structure of the entire detection part. One end of the connected breathing tube 22 is connected to the mask 23, and the other end is connected to the main body 21 of the pulmonary function detector. The pulmonary function detector flow sensor 24 arranged in the middle of the breathing tube 22 is used to measure the speed and flow of the respiratory airflow, and the pulmonary function detector pressure sensor 25 near the mask section can measure the air pressure change during the breathing process. A pulmonary function detector signal conditioning circuit 26 is fixed on the main board inside the main body 21 of the pulmonary function detector, which is connected to the pulmonary function detector pressure sensor 25 and the pulmonary function detector flow sensor 24 through a shielded wire, and amplifies, filters, and performs analog-to-digital conversion on the signals transmitted by the sensors. The pulmonary function detector microprocessor 27 is on the main board, and calculates and analyzes the processed signals to obtain breathing parameters. The Bluetooth wireless transmission module 28 is arranged on the outside of the main body 21 of the pulmonary function detector, and is used to transmit data to the control unit in the central control box 3. The exhaust port 29 is used to discharge the detected gas. In addition, a gas composition sensor 30, a temperature sensor 31 and a humidity sensor 32 are fixedly installed inside the main body 21 of the pulmonary function detector. The breathing tube 22 passes through these sensors and the exhaust port 29 in sequence. The gas composition sensor 30 can detect the concentration of gas components such as oxygen and carbon dioxide in the exhaled gas. The temperature sensor 31 and the humidity sensor 32 respectively measure the temperature and humidity of the respiratory airflow, providing multi-dimensional data for a comprehensive evaluation of respiratory function.

[0033] Central control box 3:

[0034] Located outside the airbag vest 1, a control unit, a data storage and analysis module and a prompt module are fixedly arranged inside. The control unit is connected to the pulmonary function detector 2 through a wireless signal (such as Bluetooth) to receive the respiratory parameter data transmitted therefrom, and is connected to the chest airbag vest pressure receptor network 14 and the abdominal airbag vest pressure receptor network 15 of the airbag vest 1 to receive pressure data. The data storage and analysis module can store various types of data during the entire respiratory training process, including respiratory frequency, respiratory depth, airbag vest resistance adjustment, gas component content, respiratory airflow temperature and humidity, etc. The prompt module can issue voice, vibration or light prompts according to the instructions of the control unit when the respiratory parameters deviate from the normal range, and display the current respiratory parameters, training prompt information and historical training data curves on the display screen, so that patients and medical staff can understand the training situation.

[0035] This embodiment completes the following stages in sequence during implementation:

[0036] Preparation stage:

[0037] Check the integrity of each component of the airbag vest 1, including whether the outer protective layer 11 of the airbag vest is damaged, whether the airbag units of the chest airbag layer 12 and the abdominal airbag layer 13 are leaking, whether the connection between the chest airbag vest pressure sensor network 14 and the abdominal airbag vest pressure sensor network 15 is normal, whether the inner lining layer 16 of the airbag vest is flat, and whether the airbag vest fastening device 17 can be adjusted smoothly.

[0038] Check the pulmonary function detector 2 to ensure that the breathing tube 22 is not bent or blocked, the surfaces of the pulmonary function detector flow sensor 24, the pulmonary function detector pressure sensor 25, the gas composition sensor 30, the temperature sensor 31 and the humidity sensor 32 are clean and free of foreign matter, and the pulmonary function detector signal conditioning circuit 26, the pulmonary function detector microprocessor 27 and the Bluetooth wireless transmission module 28 are working properly.

[0039] Turn on the power of the central control box 3, check whether the control unit, data storage and analysis module and prompt module are started normally, and whether the connection between the modules is stable.

[0040] Wearing and connection stage:

[0041] The user holds the cuffs of the airbag vest 1 with both hands, puts both arms into the sleeves, adjusts the position of the vest so that the chest airbag layer 12 and the abdomen airbag layer 13 correspond to the corresponding parts of the body, and then adjusts the tightness of the vest through the airbag vest fastening device 17 to make it fit closely to the body.

[0042] Wear the mask 23 on the face, adjust the position so that it fits the mouth and nose tightly, and connect the mask 23 and the pulmonary function tester body 21 with the breathing tube 22 to ensure that the connection is firm and there is no air leakage.

[0043] Training start-up and data collection phase:

[0044] The user starts to breathe naturally, and the exhaled and inhaled gases enter the breathing tube 22 through the mask 23. The pulmonary function detector flow sensor 24 and the pulmonary function detector pressure sensor 25 start to work, measuring the speed, flow size and air pressure changes of the respiratory airflow, and the gas composition sensor 30, the temperature sensor 31 and the humidity sensor 32 respectively detect the concentration of the exhaled gas components, the temperature and humidity of the respiratory airflow. After these sensor data are processed by the pulmonary function detector signal conditioning circuit 26, the pulmonary function detector microprocessor 27 calculates the breathing parameters and transmits them to the control unit in the central control box 3 through the Bluetooth wireless transmission module 28. At the same time, the chest airbag vest pressure sensor network 14 and the abdominal airbag vest pressure sensor network 15 of the airbag vest 1 sense the changes in the pressure of the respiratory muscle movement and transmit the data to the control unit.

[0045] Data analysis and training control stage:

[0046] After receiving multi-source data from the pulmonary function tester 2 and the airbag vest 1, the control unit compares and analyzes the real-time breathing parameters with the preset standard breathing parameter range. If the breathing parameters are abnormal, according to the analysis results, the control unit sends instructions to the chest airbag vest pressure receptor network 14 and the abdominal airbag vest pressure receptor network 15 of the airbag vest 1 to adjust the air pressure of the airbag unit of the chest airbag layer 12 and the abdominal airbag layer 13, apply resistance to the respiratory muscles, and stimulate the respiratory muscles to adjust breathing. For example, when the breathing depth is insufficient, the resistance of the airbag unit in the corresponding area of ​​the chest and abdomen is increased to encourage the respiratory muscles to increase the contraction force.

[0047] Feedback and training guidance stage:

[0048] When the breathing parameters deviate from the normal range, the prompt module in the central control box 3 is activated. The voice prompt function will issue corresponding voice guidance, such as "Breathing too fast, please slow down your breathing rhythm" and "The concentration of carbon dioxide in the exhaled gas is high, please breathe more deeply", etc., and generate vibration to remind the patient to adjust his breathing. The display screen synchronously displays the current breathing parameters, training prompt information and historical training data curves, so that the patient can intuitively understand his own breathing status and adjust his breathing method.

[0049] Data storage and sharing stage:

[0050] The data storage and analysis module records the breathing training data throughout the breathing training process, including various information such as breathing frequency, breathing depth, airbag vest resistance adjustment, gas composition content, breathing airflow temperature and humidity. These data can be connected to the hospital's medical information management system or the mobile terminal of medical staff through the wireless communication module (such as Wi-Fi or Bluetooth) of the central control box 3 to achieve remote data transmission and sharing. Medical staff can evaluate the training effect of patients based on the data, formulate personalized training plans or provide remote guidance.

[0051] End of training phase:

[0052] After the user completes the breathing training, he stops breathing and turns off the power of the pulmonary function tester 2, the central control box 3 and other equipment in turn.

[0053] Carefully take off the airbag vest 1, organize the mask 23, breathing tube 22 and lung function tester 2 and other equipment, and store them in a dry, clean and safe place for next use.

[0054] The technical effects of this embodiment are as follows:

[0055] Accurate breathing monitoring:

[0056] Through the cooperation of multiple sensors in the pulmonary function detector 2 (pulmonary function detector flow sensor 24, pulmonary function detector pressure sensor 25, gas composition sensor 30, temperature sensor 31 and humidity sensor 32) and the chest airbag vest pressure receptor network 14 and the abdominal airbag vest pressure receptor network 15 of the airbag vest 1, multiple parameters in the breathing process can be comprehensively and accurately collected, including the speed, flow, air pressure, gas composition, temperature, humidity and pressure changes of respiratory muscles of the respiratory airflow. These rich data provide a solid foundation for the accurate evaluation of respiratory function, whether it is the basic indicators of respiratory frequency and depth, or the deep-level indicators such as lung gas exchange efficiency and respiratory tract physiological state, can be accurately monitored.

[0057] Personalized breathing training control:

[0058] The control unit analyzes the received multi-source data and can formulate personalized training plans based on the breathing characteristics and abnormal conditions of different patients. For example, for patients with weak respiratory muscles, the control unit can adjust the air pressure of the airbag unit of the chest airbag layer 12 and the abdominal airbag layer 13 of the airbag vest 1 to apply appropriate resistance at different stages of breathing, so as to train the respiratory muscles in a targeted manner and gradually improve their strength and coordination. For patients with abnormal respiratory rhythm, according to the deviation of the respiratory parameters from the normal range, the control unit can adjust the resistance of the airbag unit during exhalation or inhalation to guide the patient to restore the normal respiratory rhythm, thereby realizing personalized and precise respiratory training control.

[0059] Real-time feedback and guidance:

[0060] The existence of the prompt module enables patients to get timely feedback during the breathing training process. When the breathing parameters deviate from the preset standards, voice prompts, vibration prompts and information displayed on the display screen allow patients to intuitively understand their breathing status and adjust their breathing methods according to the prompts. This real-time feedback and guidance mechanism helps patients better master breathing training skills and improve training effects. It can also enhance patients' self-management awareness and enable them to participate more actively in respiratory rehabilitation training.

[0061] Data Management and Telemedicine Support:

[0062] The large amount of breathing training data recorded by the data storage and analysis module can not only be used to evaluate the patient's training progress and effect locally, but also to achieve remote data transmission and sharing through the wireless communication module. Medical staff can view the patient's data remotely, understand the patient's training status in a timely manner, and provide a basis for formulating further treatment plans. In the telemedicine scenario, even if the patient is training at home, medical staff can monitor and guide the patient as if they were in the hospital, breaking through the limitations of time and space, and improving the accessibility and effectiveness of medical services, which is especially important for patients with limited mobility or living in remote areas.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
