Description

Technical Field

[0001] The present invention relates to the technical field of pulmonary function breathing training, and more particularly to an adjustable pulmonary function breathing rehabilitation training device. Background Art

[0002] With the high incidence of respiratory diseases such as chronic obstructive pulmonary disease (COPD), pneumonia, and postoperative pulmonary function decline, the demand for pulmonary function rehabilitation among patients has increased significantly. As an auxiliary treatment device, a breathing rehabilitation training device helps improve the strength of respiratory muscles, restore vital capacity, and enhance the overall pulmonary function of patients by providing resistance breathing training.

[0003] A pulmonary function breathing rehabilitation training device adjusts the airflow resistance through the internal structure of the device. When a patient breathes against the resistance, the respiratory muscles are exercised and strengthened. Some devices follow volume control, presetting the tidal volume in advance and guiding the patient to inhale as much as possible to reach this goal, thereby strengthening the lung expansion function. Others use positive pressure ventilation to provide positive pressure to assist gas entry into the lungs, optimize the ventilation condition, and facilitate the pulmonary function rehabilitation of patients.

[0004] Existing pulmonary function rehabilitation training devices have low resistance adjustment accuracy and are difficult to meet the personalized needs at different stages; lack real-time data collection and feedback functions, so the training effect cannot be quantified and the rehabilitation plan cannot be dynamically adjusted; have no oxygen supply function and lack safety protection; in addition, the device design is bulky and inconvenient to clean, and bacteria are likely to breed during long-term use, with poor portability and applicability, which limits the use in home and mobile scenarios. Therefore, an adjustable pulmonary function breathing rehabilitation training device is proposed to solve the above problems. Summary of the Invention

The locking mechanism 3 provides the stability of the equipment through the action of the slider body 303 and the spring 302, and allows quick disassembly when necessary for easy repair or maintenance.

[0045] Please refer to the appendix Figure 8, the locking mechanism 3 includes a square box 301. The square box 301 is arranged inside the main body 201 of the detector.

At the same time, it is closely connected to the overall structure of the device. The slider bodies 303 can slide between the inner walls of the square box 301 and maintain a certain elastic pressure under the action of the springs 302, so that the components can be firmly engaged, avoiding loosening or displacement. The existence of the springs 302 provides a buffering and restoring function for the locking mechanism 3. When the slide plate 304 or the latch rod 305 is subjected to an external force, it can quickly reset and maintain the fixed state of the components. The slide plate 304 and the latch rod 305 are respectively located on the outer sides of the slider bodies 303.

[0046] Please refer to the appendix Figure 9 , the central control system includes:

[0047] Monitoring module: It is used to transmit the data collected by the oxygen sensor 209, pressure sensor 2010, flow sensor 2011 and solenoid valve 2015 to the central control system;

[0048] Analysis module: It analyzes the data collected in the central control system through the data processing unit;

[0049] The central control system includes a monitoring module and an analysis module. The monitoring module receives the data from the oxygen sensor 209, pressure sensor 2010, flow sensor 2011 and solenoid valve 2015 in real time and transmits it to the analysis module. The analysis module processes the collected data and feeds it back to the patient or doctor through the central control system to optimize the training process and improve the rehabilitation effect.

[0050] Working principle: When the patient performs breathing training through the mouth mask 8, first determine whether to practice blowing or inhaling. If blowing, pull the U-shaped cover 103 upward to leak the upper strip vent 106, and then adjust the three-way valve 904 to control the distribution direction of the airflow and control the airflow to flow downward; conversely, similarly, by adjusting the knob 507 in the adjustment mechanism 5, the worm 505 is driven to rotate, which in turn drives the worm wheel 506 and the bidirectional screw 501 to rotate, thereby driving the T-shaped slider 502 and the arc block The flow block 503 moves closer or further away, thereby adjusting the resistance inside the airway tube 208. The patient then performs breathing training through the mouth mask 8. The gas first enters the flexible tube 4, and then the airway tube 208 guides the gas into the detector body 201. After entering the detector body 201, the gas flows through the pressure sensor 2010, the oxygen sensor 209, and the flow sensor 2011. These sensors respectively collect data on the pressure, oxygen concentration, and flow rate of the airflow, and transmit these data in real time to the central control system for analysis and processing;

[0051] The gas passes through the three-way valve 904 and then flows into the interior of each cylinder 104 through the L-shaped tube 901, pushing the small ball 1011 inside to rise. The change in the inflated volume in the cylinder 104 is intuitively displayed. In addition, the external display screen 205 of the detector body 201 can also be used to display the patient's training data in real time, including pressure, flow rate, oxygen concentration, etc. The strip-shaped vent hole 106 is used to maintain a consistent atmospheric pressure inside the cylinder 104.

[0052] If the oxygen concentration is detected to be too low, the oxygen interface 203 inputs oxygen into the detector body 201 by connecting to an external oxygen source. The oxygen first enters the mixing chamber 2014 and is fully mixed with the air entering through the air inlet 2013. The mixed gas is then delivered to the airway 208 through the electronic valve 2015 and then to the patient's mouth mask 8 through the flexible tube 4.

[0053] Among them, the monitoring module of the central control system receives data from the oxygen sensor 209, pressure sensor 2010, flow sensor 2011 and electronic valve 2015 in real time. The analysis module processes and analyzes the collected data to provide feedback for the patient's breathing training, and automatically adjusts the resistance parameters and oxygen supply ratio of the device according to the patient's actual condition to achieve the best rehabilitation effect.

[0054] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
