Description

Technical Field

[0001] The present invention relates to the technical field of respiratory training, in particular to a respiratory training device. Background Art

[0002] The breathing trainer can apply additional impedance to the patient's respiratory movement, so that the patient's respiratory muscles can be exercised in the process of overcoming the impedance, thereby exercising the respiratory muscle groups, enhancing the strength and endurance of the respiratory muscles, and improving the ventilation function of the lungs. When in use, connect the hose to the interface on the outside of the device, and then connect the other end of the hose to the mouthpiece. Adjust the appropriate impedance level according to the patient's condition, respiratory function and training goals. During training, the patient needs to hold the mouthpiece for deep breathing training. During inhalation training, try to rely on the inhalation action to make the float rise to the corresponding scale. During exhalation training, control the exhalation speed and strength to keep the float in a certain position or slowly lower it.

[0003] For example, CN114432669A discloses a pediatric breathing training device. The present invention provides a pediatric breathing training device that can filter water vapor and adjust the gas flow rate. The pediatric breathing training device includes an outer frame, a first baffle, a first airway tube, a second airway tube, a fourth fixing plate, a second baffle, etc.; the fourth fixing plates are provided on the left and right sides of the outer frame, and the second baffles are slidably provided inside the two fourth fixing plates. The first baffle is placed on the left side of the outer frame, and a circular hole is opened in the middle of the first baffle. The first airway tube is provided on the left side of the outer frame and passes through the circular hole of the first baffle. The second airway tube is provided in the middle of the outer frame. The second baffle on the left side is located between the first airway tube and the second airway tube. When people rotate the rotating rod, the rotating rod will drive the circular baffle to rotate, and then the circular baffle will limit the flow of gas flowing in the first airway tube, so as to facilitate the adjustment of the flow rate of gas in the first airway tube and enhance the intensity of children's breathing training.

[0004] However, patients need to pay attention to the position of the float at all times during training, which can easily distract patients from the breathing action itself. At the same time, fluctuations in respiratory airflow can cause the float to shake, making it difficult for patients to accurately determine the exact position of the float, affecting the patient's breathing training effect and the ease of operation of the trainer. Summary of the Invention

[0005] In view of this, the present invention provides a breathing training device, which increases the fun of the trainer through interesting retractable air bags and interesting rotating windmills, allowing patients to complete training in an entertaining way. Patients will be more actively involved in training and no longer regard it as a burden, thereby increasing the frequency and duration of training. Patients will breathe more naturally and smoothly, making the training process more comfortable and efficient, and can relieve patients' anxiety and tension caused by the disease, form positive psychological hints, and promote the overall recovery of patients. After the position marker float moves to the standard position, the sound and light alarm can automatically sound an alarm to remind the patient of the effectiveness of this training, effectively avoiding the need to pay attention to the position of the position marker float at all times, ensuring the patient's concentration on the breathing action itself, and avoiding the situation where it is difficult for patients to accurately determine the position of the position marker float. It ensures the patient's breathing training effect and improves the operational convenience of the trainer. The filtering water-absorbing sponge can filter the blown-in gas and absorb the moisture in the gas at the same time. The water absorbed by the filtering water-absorbing sponge is squeezed out by the movement of the sliding extrusion plate, which is convenient for discharging the moisture out of the trainer, effectively avoiding the situation where many water droplets condense inside the trainer and are difficult to clean, reduces the breeding of bacteria, and effectively improves the hygiene of the trainer. The air inlet end is sealed by the sealing conical baffle when the trainer is not in use, effectively avoiding impurities falling into the trainer, avoiding the situation where the trainer pipeline is blocked by impurities, reducing the number of inspections of the trainer, and effectively improving the service life of the trainer. By adjusting the impedance of the trainer, patients at different training stages can use the trainer conveniently, effectively ensuring the applicability of the trainer.
