The training method of the rehabilitation training device includes: (1) When performing inhalation training, place the rehabilitation training device upright. Chronic obstructive pulmonary disease patients inhale through the breathing trachea. The inhalation power enters the lumen of the training tube body along the breathing cavity and the connecting through groove respectively and acts on the training ball, so that the training ball moves upward along the training tube body. The effect of inhalation training is judged by observing the movement of the training ball; during this training process, the gravity switch controls the operation of the heating grid plate to heat the air inhaled by the patient; at the same time, the shape memory alloy beam ring expands when heated during the process of the temperature rise inside the connecting through groove, and the porosity inside the drying column remains constant; (2) When performing exhalation training, the rehabilitation training device is used upside down as a whole. Chronic obstructive pulmonary disease patients exhale through the breathing tube. The exhalation power enters the lumen of the training tube body along the breathing cavity and the connecting groove respectively and acts on the training ball, causing the training ball to move upward along the training tube body. The effect of exhalation training is judged by observing the movement of the training ball. During this training process, the gravity switch controls the heating grid plate to stop working.

The design of the rehabilitation training device of the present invention pays attention to user experience, and has the advantages of simple operation, safety and reliability, convenient use, strong adaptability, etc.; it is made of high-quality materials to ensure its durability and environmental adaptability.

[0016] 2. The rehabilitation training device has the advantage of intelligence. Through the set gravity switch, heating grid plate and drying component, it can automatically heat the air in the breathing cavity during inhalation training, making the inhaled gas have a higher temperature, effectively preventing the discomfort caused by the inhalation of cold air into the patient's body. During exhalation training, it can automatically increase the airflow resistance of the drying column, which is applicable to the application scenario where chronic obstructive pulmonary disease patients have long-term damaged airways and poor exhalation ability. It is automatically adjusted and relatively convenient.

[0017] 3. The rehabilitation training device is more widely used in clinical applications, especially suitable for the rehabilitation treatment of patients with chronic obstructive pulmonary disease, after lung resection, and respiratory muscle dysfunction. Patients can perform regular pulmonary function training at home or in a rehabilitation center, improve their quality of life, and accelerate the rehabilitation process.

[0018] 4. The training tube body of the training component and its training ball prevent condensate on its inner wall, the inner wall of the positioning cavity, and the surface of the training ball, resulting in the problem of adhesion of the training ball during the movement process, and improving the smoothness of the training ball during the movement process; at the same time, during the installation process, the drying cavity provided at the top of the training tube body can position the drying component, improving the convenience of connecting the drying component and the training tube body.

Detailed Embodiments

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be combined with the attached Figures 1 - 7Describe the technical solutions of the embodiments of the present invention clearly and completely. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention fall within the scope of protection of the present invention.

[0023] Embodiment 1: As Figures 1 - 3 and Figures 6 - 7 shown, a rehabilitation training device for pulmonary respiratory function of the present invention, the rehabilitation training device 100 includes a box body 1, a box cover 2, a breathing tube 6, a training component 9, a drying component 10, a heating grille plate 7 and a power supply unit 3.

[0024] As Figure 4 shown, a breathing cavity 11 with an open upper end and three positioning cavities 12 are longitudinally arranged in the box body 1. The inner diameter of the breathing cavity 11 is 1 / 3 to 2 / 1 of the inner diameter of the positioning cavity 12. This setting can increase the amplification ability of the breathing cavity 11 for exhalation or inhalation when used by patients, thereby improving the training effect. A support substrate 14 is arranged at the bottom end of the box body 1, and the area of the support substrate 14 is larger than the bottom area of the box body 1, so as to realize stable support for the box body 1.

[0025] As Figures 1 - 4 shown, the box cover 2 is correspondingly connected to the open end of the box body 1. A connecting through groove 21 is arranged in the box cover 2, and a limiting support plate 22 is arranged at the open end of the connecting through groove 21. A breathing through hole 23 and a mounting slot hole 25 are respectively arranged on the limiting support plate 22 corresponding to the breathing cavity 11 and the positioning cavity 12. Sealing rings 13 are arranged at the open ends of the top of the breathing cavity 11 and the positioning cavity 12. The box cover 2 is correspondingly buckled on the box cover 2 so that the breathing cavity 11 is connected to the breathing through hole 23 and the positioning cavity 12 is connected to the mounting slot hole 25 to form a sealed structure. Matching connecting buckles 4 and connecting blocks 5 are respectively arranged at both ends of the box body 1 and the box cover 2. The connecting buckle 4 correspondingly buckles or disengages from the connection with the connecting block 5, so as to facilitate the fixed connection or disassembly of the box cover 2 and the box body 1, and further facilitate the cleaning treatment of the training component 9 and the positioning cavity 12.

[0026] As Figure 2 and Figures 4 - 5 shown, the breathing tube 6 includes a breathing hose 61. One end of the breathing hose 61 is provided with a connection end 62 that is connected to the side wall of the box body 1 and communicates with the breathing cavity 11. A limiting block 15 for clamping the free end of the breathing hose 61 is arranged on the side wall of the box body 1. A card slot is arranged in the limiting card slot. The limiting block 15 can be correspondingly arranged at the bottom of one side of the box body 1. The limiting block 15 positions the distal end of the breathing hose 61 through the card slot. This setting can fixedly store the breathing hose 61 when it is idle.

[0027] As Figure 2 andFigure 6 As shown, there are three training components 9. The training component 9 includes a training tube body 91 correspondingly inserted into the positioning cavity 12. A training ball 94 adapted to the inner diameter of the tube cavity 92 is floatingly arranged in the training tube body 91. A limiting ring 95 is arranged in the top open end thereof, and a drying cavity 96 is formed on the top of the limiting ring 95. An external thread area 97 is arranged on the outer wall of the top end of the training tube body 91, and an internal thread area adapted to the external thread area 97 is arranged on the inner wall of the installation slot hole 25. When installing, rotating the training tube body 91 can realize the fixed connection with the limiting support plate 22. A communicating slit 93 is arranged along the side wall of the training tube body 91. The communicating slit 93 includes two arranged axially along the front and rear side walls of the training tube body 91. This kind of setting can not only facilitate the drainage of the training tube body 91 and the training ball 94 therein, but also realize the communication with the positioning cavity 12, reducing the possible resistance during the patient's exhalation or inhalation.

[0028] As Figure 3 and Figure 7 As shown, the drying component 10 includes a drying box body 101 and a flexible inner box 103. An installation retaining ring 24 is arranged at the top end of the installation slot hole 25, and a clamping flange 106 is arranged at the top end of the drying box body 101. The drying box body 101 is correspondingly inserted into the installation slot hole 25 so that the clamping flange 106 is correspondingly supported on the installation retaining ring 24. A drying column 105 is arranged in the flexible inner box 103. A plurality of limiting ring grooves 102 are arranged on the inner wall of the drying box body 101, and a plurality of shape memory alloy coil rings 104 correspondingly clamped in the limiting ring grooves 102 are arranged on the outer wall of the flexible inner box 103. The shape memory alloy coil rings 104 expand or contract when heated or pre-cooled to adjust the porosity of the drying column 105, thereby realizing the regulation of the resistance to the air flow passing through the drying column 105. The inner diameter of the training tube body 91 is larger than the outer diameter of the drying box body 101 and smaller than the outer diameter of the clamping flange 106. This kind of setting can make the bottom end of the drying component 10 hermetically supported on the drying cavity 96 of the training tube body 91 when the drying component 10 is correspondingly clamped in the installation slot hole 25, and the air flow is dried through the drying column 105 during the exhalation or inhalation process.

[0029] As Figures 1 - 3As shown in the figure, a heating grid plate 7 is correspondingly arranged on the side of the connecting through groove 21 close to the breathing through hole 23. The heating grid plate 7 divides the connecting through groove 21 into two parts with the breathing cavity 11 and the positioning cavity 12 as the dividing line. The air flow of the training tube body 91 entering and leaving the positioning cavity 12 from the breathing cavity 11 will flow through the heating grid plate 7 in the connecting through groove 21. The power supply unit 3 is correspondingly arranged at the top of the box body 1 and is electrically connected to the heating grid plate 7 through the gravity switch 8. The power supply unit 3 is powered by a rechargeable lithium battery. The gravity switch 8 can control the power supply unit 3 to supply power to the heating grid plate 7, and automatically control the heating grid plate 7 to heat the air flow during inhalation training, so that the temperature of the gas inhaled by the patient is relatively high, effectively preventing discomfort caused by the inhalation of cold air into the patient's body; during exhalation training, the gravity switch 8 can control the power supply unit 3 to cut off the power so that the heating grid plate 7 stops working.

[0030] In the embodiment of the present invention, the box body 1, the box cover 2 and the training tube body 91 are all made of transparent materials, and the movement of the training ball 94 in the training tube body 91 during the training process can be conveniently observed to determine the effect of the breathing training.

[0031] In the embodiment of the present invention, the number of the positioning cavities 12 arranged in the box body 1 can be set according to requirements, not limited to three, and the numbers of the corresponding training components 9, the drying components 10 and the installation slot holes 25 are consistent with the number of the positioning cavities 12.

[0032] Embodiment 2: As Figures 1 - 7 shown, the present invention also discloses a rehabilitation training method for pulmonary respiratory function. The training method of the rehabilitation training device includes the step of assembling the rehabilitation training device, and when the rehabilitation training device is assembled, it can be used normally.

[0033] (1) During inhalation training, place the rehabilitation training device upright. The patient with chronic obstructive pulmonary disease inhales through the breathing tube 6. The inhalation power enters the lumen of the training tube body 91 along the breathing cavity 11 and the connecting through groove 21 respectively and acts on the training ball 94, so that the training ball 94 moves upward along the training tube body 91. The effect of the inhalation training is determined by observing the movement of the training ball 94; during this training process, the gravity switch 8 controls the heating grid plate 7 to operate to heat the air inhaled by the patient; at the same time, the shape memory alloy coil 104 expands due to heat during the process of the internal temperature of the connecting through groove 21 rising, and the porosity inside the drying column 105 remains constant.

[0034] (2) When performing exhalation training, the rehabilitation training device is used upside down as a whole. Chronic obstructive pulmonary disease patients exhale through the breathing trachea 6. The exhalation power enters the lumen of the training tube body 91 along the breathing cavity 11 and the connecting through groove 21 respectively and acts on the training ball 94, so that the training ball 94 moves upward along the training tube body 91. The effect of exhalation training is determined by observing the movement of the training ball 94. During this training process, the gravity switch 8 controls the heating grid plate 7 to stop working. The shape memory alloy coil 104 pre-cools and contracts during the process of the internal temperature of the connecting through groove 21 decreasing, prompting the porosity of the drying column 105 to decrease, increasing the resistance of the drying column 105 to the airflow passing through. Since the airways of chronic obstructive pulmonary disease patients are damaged for a long time, the exhalation ability of the patients is usually poor. Setting a higher exhalation resistance helps the patients improve the exhalation efficiency. More waste gas can be discharged during training, increasing the ventilation volume of the lungs.

[0035] After each breathing training, remove the box cover 2 from the top of the box body 1, then remove the training tube body 91 from the installation slot hole 25, and clean and dry the inner wall of the positioning cavity 12, the inner and outer walls of the training tube body 91 and the training ball 94 for the next use, which can prevent the adhesion problem of the training ball 94 during the up and down movement in the training tube body 91 and improve the smoothness of the movement of the training ball 94.

[0036] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
