The present application relates to the field of virtual reality, in particular to a lung rehabilitation nursing psychological counseling method and system based on virtual reality. The method collects the chest and abdominal girth change signal of the patient, calculates the respiratory flow rate curve through band pass filtering and peak detection algorithm, identifies the inspiration starting point, expiration starting point and breath holding starting point on the respiratory flow rate curve as the respiratory phase turning point. The digital phase-locked loop mechanism is introduced, the respiratory phase turning point is taken as the reference clock signal, the actual presentation time of the virtual visual and auditory stimulation is taken as the output signal of the voltage-controlled oscillator, the rendering pipeline delay of the visual and auditory generation component is adjusted through closed-loop feedback, so that the phase delay of the virtual visual and auditory stimulation is constantly within the preset neuromuscular response threshold. The present application eliminates the phase lag and drift phenomenon between the audio-visual guide signal and the real breathing action of the patient, and enhances the neural drive synchronization of the diaphragm and auxiliary respiratory muscles under the rhythmic audio-visual stimulation.

This application discloses a method and apparatus for regulating expiratory switching. The method includes: acquiring the user's proximal pressure and the total airflow within the target ventilator during a preset time period of the expiratory phase of the respiratory cycle; determining a predicted user flow rate based on the user's proximal pressure and total airflow; determining a predicted respiratory muscle exertion value based on the predicted user's proximal pressure and user flow rate; and controlling the target ventilator to switch from the inspiratory phase to the expiratory phase in response to the predicted respiratory muscle exertion value meeting a preset condition. Using the user's respiratory muscle exertion as the determination information can accurately reflect the user's voluntary intention to switch between inspiratory and expiratory phases, improving the human-ventilator synchronization during expiratory switching.

This invention relates to the field of respiratory care technology and discloses a pre-operative respiratory function trainer for respiratory endoscopy, comprising a base and a mouthpiece. A mounting base is fixedly connected to the top of the base, and an air cylinder is fixedly connected to the top of the mounting base. A float is disposed within the inner cavity of the air cylinder, and a training component is disposed within the inner cavity of the mounting base. This invention integrates respiratory training, air filtration, real-time monitoring, and data display functions into a compact structure, specifically designed for patients before respiratory endoscopy. It effectively trains the patient's respiratory muscle strength and vital capacity. Through the monitoring component, particularly the pressure sensor and pressure value display screen, the patient's blowing force can be converted into specific numerical values ​​in real time and displayed, making the training effect measurable and recordable. Simultaneously, the range scale on the surface of the air cylinder and the rising height of the float provide the user with direct visual feedback, helping to maintain and enhance training motivation.

The system includes: collecting signals related to respiratory muscle mechanics, airway airflow, chest wall movement, and body posture; filtering and separating these signals; extracting respiratory muscle fatigue features; analyzing respiratory impedance features; processing the relationship between posture and respiratory coordination; and then integrating the feature parameters from each dimension to generate a dynamic monitoring dataset and outputting real-time assessment results. This achieves end-to-end coordination of signal acquisition, feature extraction, data integration, and assessment. The system comprises a multimodal sensor signal acquisition unit, a signal filtering and separation unit, a respiratory muscle fatigue feature extraction unit, a respiratory impedance feature analysis unit, a posture-respiratory coordination processing unit, and a data integration and assessment unit. This ensures efficient and smooth signal transmission and processing, comprehensively captures key physiological state changes during training, improves the comprehensiveness of monitoring and the accuracy of assessment, and provides scientific support for respiratory rehabilitation training.

The present invention relates to a method and a preparation for treating inflammatory diseases of the respiratory tract in horses, in particular equine asthma, by inhalational administration of aviptadil or another receptor agonist of the VIP receptor (VPAC1 and VPAC2 receptors). Vasoactive intestinal peptide (VIP) is a neuropeptide with anti-inflammatory and bronchodilatory properties, which, when synthetically produced (INN = aviptadil), can be used specifically to reduce inflammation and relax the respiratory muscles. In a preferred embodiment, the effect of aviptadil is enhanced by the simultaneous or prior administration of N-acetylcysteine ​​(ACC). Aviptadil is suitable for treating horses because equine VIP and human VIP are sequence-identical.

The application provides a lung function rehabilitation device for respiratory care, and relates to the technical field of medical equipment, which comprises a box body with at least three independent upright cavities, and at least two of the upright cavities are convex in cross section. The application realizes dynamic and gradually increasing airflow resistance training through the convex ball and the ball contact linkage mechanism. When the airflow lifts the ball and precisely embeds the convex ball into the recess, the shunt airflow pushes the convex ball downward, the elastic extension part embedded with a counterweight ring accelerates to cover the ventilation groove, the exhalation resistance increases smoothly with the increase of strength, and the respiratory muscle exercise is strengthened. Meanwhile, the convex matching structure guide part moves along the set path, the airflow escape buffer and the contact surface friction are used to effectively avoid rigid impact, and the service life of the equipment is prolonged. The communication cavity valve independently controls the opening and closing of the multi-cavity, supports flexible grading and combination training mode, and adapts to the needs of different rehabilitation stages.
