Description

Technical Field

[0001] The utility model relates to the field of lung rehabilitation, in particular to a lung rehabilitation training device Background Art

[0002] After thoracic surgery, restrictive ventilatory dysfunction occurs. This means that the total lung capacity and functional residual capacity decrease. The minimum vital capacity can drop to about 40% of the preoperative vital capacity, and the degree of decrease depends on the surgical method. This pulmonary dysfunction can cause mild atelectasis, which can lead to gas exchange disorders, secretion retention, and lung or tracheal infection. Clinical manifestations are hypoxemia, increased respiratory rate, decreased tidal volume and vital capacity, fever, cough, and dyspnea. High-risk factors for these complications may be the presence of chronic obstructive pulmonary disease, obesity, cachexia, and neuromuscular diseases before surgery. Improving this restrictive pulmonary dysfunction is crucial to preventing pulmonary complications. The basic principle of physical therapy is to improve the patient's functional indicators before surgery and reduce the risk of postoperative complications; maximize continuous ventilation after surgery. The specific operation includes first recruiting the lungs as much as possible to ventilate the underventilated areas; then take deep breaths, exhale forcefully, and cough to clear airway secretions.

[0003] After children undergo lung surgery, all patients undergoing thoracic surgery clinically need to perform respiratory function exercises. However, there are currently no suitable and interesting instruments in clinical practice that can both exercise lung function and allow patients to see the improvement in their lung function, and patient compliance is poor.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 , the utility model provides a technical solution: a pulmonary rehabilitation trainer, comprising a mouthpiece 1, an oscillator 2 detachably connected to the mouthpiece 1, and an exerciser 3 detachably connected to the mouthpiece;

[0026] The mouthpiece 1 comprises an arc-shaped bite opening 11 and a locking opening 12;

[0027] The oscillator 2 includes a housing 21 detachably connected to the mouthpiece 1 , an oscillation rod 25 capable of causing air oscillation, an air pipe 23 through which air can pass, and a one-way valve 24 through which air can pass in a one-way direction toward the mouthpiece 1 .

[0028] The exerciser 3 comprises a connection port which is detachably connected to the mouthpiece 1 , and a curled air bag 32 which can be expanded by air flow is connected to one end of the connection port away from the mouthpiece 1 .

[0029] The shell 21 is provided with a connection port for detachable connection with the mouthpiece 1, the inner wall of the shell 21 is connected with an air pipe 23 opposite to the connection port, the air pipe 23 is provided with a tapered end 231, a vent 232 is provided on the side wall of the tapered end 231 close to the mouthpiece 1, the end of the air pipe 23 away from the mouthpiece 1 is connected with a one-way valve 24, the one-way valve 24 is a gas one-way valve, the inner wall of the shell 21 is limitedly connected with an oscillation rod 25, the oscillation rod 25 is provided with a tapered protrusion corresponding to the tapered end 231, and the oscillation rod 25 is provided with a suction mechanism 4.

[0030] refer to Figure 2-3 As shown,

[0031] Normally, the mouthpiece 1 is not connected to the oscillator 2 and the exerciser 3 .

[0032] The air pipe 23 inside the oscillator 2 is provided with a tapered end 231 fixed to the tapered protrusion of the oscillation rod 25, and the vent 232 is blocked by the oscillation rod 25;

[0033] The airbag 32 of the exerciser 3 is in a rolled-up state.

[0034] When in use, when expectoration is performed, the mouthpiece 1 is threadedly connected to the housing 21 , and the patient bites the bite opening 11 .

[0035] During inspiration, airflow passes unidirectionally through the trachea 23 to the patient's mouth;

[0036] When exhaling, the air flows through the vent 232, blowing the oscillation rod 25, causing the end of the oscillation rod 25 away from the mouthpiece 1 to lift up, and the air flows out through the vent 232, and then the metal rod 41 of the suction mechanism 4 and the magnet 42 are attracted to each other, causing the oscillation rod 25 to return to its original position (the air flows upward through the vent 232 to blow the oscillation rod 25 upward, because the air flows through the bottom of the oscillation rod 25, thereby generating a pressure difference, which attracts the oscillation rod 25 to move downward, and the oscillation rod 25 falls back under the action of its own gravity, the suction mechanism and the pressure difference), and the auxiliary conical end 231 is fixed to the conical protrusion again, temporarily blocking the vent 232, thereby causing the air flow to oscillate, thereby promoting the shedding and discharge of secretions in the trachea.

[0037] refer to Figure 2 As shown, the attraction mechanism 4 includes a metal rod 41 connected to one end of the oscillation rod 25 and a magnet 42 connected to the inner wall of the housing 21. The magnet 42 is located below the metal rod 41. The tapered end 231 is fixed to the tapered protrusion through the attraction between the metal rod 41 and the magnet 42.

[0038] At the same time, in order to facilitate the shedding and discharge of secretions in the trachea, the air oscillation frequency generated by the oscillation rod 25 is 0-23Hz, which is consistent with the frequency of cilia vibration in the lungs, and can cause resonance. Vibration drives the vibration in the chest cavity, thereby promoting the shedding and discharge of secretions in the trachea, promoting the discharge of sputum, and preventing postoperative pneumonia, atelectasis, and sputum blockage leading to breathing difficulties.

[0039] Then, when performing breathing exercises, the mouthpiece 1 is threadedly connected to the connecting port of the exerciser 3, and the patient bites the bite port 11 with his mouth, and blows air into the inside, so that the curled air bag 32 is filled with airflow and opens, and then inhales and curls again, and the reciprocating operation is performed to achieve the operation of exercising the patient's breathing.

[0040] refer to Figure 4 As shown, in order to facilitate the patient to observe the degree of his breathing exercise, the surface of the airbag 32 is coated with multiple different color blocks, and each color block is a different color. When the patient exhales, the color blocks on the surface of the open airbag 32 can instruct the patient to observe the degree of his exercise, while also enhancing the interest of the breathing exercise.

[0041] In order to improve the oral comfort of the patient, a silicone layer is laid on the surface of the bite opening 11, and a counter is set on the side wall of the mouthpiece 1. The sensor of the counter is set on the inner wall of the mouthpiece 1 near the bite opening 11. When the patient bites, the pressure on the lips can be reduced, and the patient's oral comfort can be increased. The counter can record the number of exercises of the patient. The sensor can be a temperature sensor or a differential pressure sensor, which determines whether to blow through the temperature change or the pressure difference caused by the tassel. The electrical signal sent after the judgment is received by the counter and counted.

[0042] In order to avoid affecting the air vibration effect and the breathing exercise effect, a plurality of sealing sleeves are embedded in the inner wall of the locking port 12 to reduce the outflow of gas after the mouthpiece 1 is connected to the oscillator 2 and the exerciser 3, thereby avoiding affecting the air vibration effect and the breathing exercise effect.

[0043] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
