The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0027] In the description of this application, it should be understood that the terms "inside", "outside", "front", "back", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0028] A lung capacity training device, such as Figure 1 As shown, it is composed of an air blowing tube 1, a balloon 3, an elastic clamp ring 4, a first pipe hoop 5, a circular baffle 6 and a handle 7.

[0029] like Figure 1 and Figure 2 As shown, an annular boss 2 is fixed to the outer wall of the left end of the insufflation tube 1, and a mouthpiece 8 is installed at the right end. When the patient holds the mouthpiece 8 in his mouth and blows air, the mouthpiece 8 is not easy to fall out of the mouth and air is not easy to leak at the mouthpiece 8, which can facilitate the patient's balloon blowing training;

[0030] Specifically, the mouthpiece 8 is made of silicone material and is bonded and fixed to the right end of the air tube 1. The silicone mouthpiece 8 can protect the patient's teeth; in addition, the mouthpiece 8 can also be made of plastic and be integrally formed with the air tube 1.

[0031] like Figures 1 to 4 As shown, an annular groove 9 is formed on the outer wall of the annular boss 2, and the ball mouth of the balloon 3 is sleeved on the annular boss 2. The elastic clamp ring 4 is sleeved on the annular boss 2 to tighten the ball mouth of the balloon 3. The elastic clamp ring 4 is made of elastic rubber material (or elastic silicone material). The elastic clamp ring 4 can be stretched by hand to be sleeved on the annular boss 2 and sleeved outside the ball mouth of the balloon 3. After releasing the hand, the elastic clamp ring 4 contracts to tighten the ball mouth of the balloon 3 to the annular boss 2, which can prevent the ball mouth of the balloon 3 from falling off and leaking.

[0032] The elastic clamp ring 4 can be inserted into the annular groove 9 to fix the ball mouth clamp of the balloon 3 in the annular groove 9; the annular groove 9 can limit the elastic clamp ring 4 to prevent the elastic clamp ring 4 from shifting, thereby improving the clamp fixing effect of the elastic clamp ring 4 on the ball mouth of the balloon 3 and improving the stability and sealing of the ball mouth of the balloon 3.

[0033] like Figures 1 to 4As shown, the first pipe clamp 5 includes two arc-shaped clamping plates 5.1, which together form a circular clamp ring that can be clamped on the annular boss 2. Both ends of each arc-shaped clamping plate 5.1 are integrally formed with flanges 5.2. A screw 5.3 is fixed to the two flanges 5.2 of one arc-shaped clamping plate 5.1, and a through hole for the screw 5.3 to pass through is formed on the two flanges 5.2 of the other arc-shaped clamping plate 5.1. The end of the screw 5.3 is threadedly connected to a nut 5.4;

[0034] Two arc-shaped clamps 5.1 are clamped on the annular boss 2, and the elastic clamp ring 4 is clamped inside. Tightening the nut 5.4 can fix the two corresponding flanges 5.2 together. In this way, the two arc-shaped clamps 5.1 squeeze the elastic clamp ring 4, clamping the elastic clamp ring 4 to the annular boss 2, and the elastic clamp ring 4 clamps the ball nozzle of the balloon 3 to the annular boss 2. This can enhance the stability and sealing between the ball nozzle of the balloon 3 and the annular boss 2, preventing the ball nozzle of the balloon 3 from falling off or leaking during balloon blowing training.

[0035] In the above structure, the first tube hoop 5 is detachably clamped on the annular boss 2, and the elastic clamp ring 4 is detachable. After removing the first tube hoop 5 and the elastic clamp ring 4, the balloon 3 can be removed and replaced with a new balloon 3 during the next balloon blowing training.

[0036] like Figure 2 and Figure 4 As shown, the inner wall of each of the arc-shaped splints 5.1 is provided with an arc-shaped positioning groove 10, and the outer edge of the elastic clamp ring 4 can be clamped into the arc-shaped positioning groove 10 to limit the elastic clamp ring 4 and the arc-shaped splint 5.1, thereby avoiding displacement of the elastic clamp ring 4 or the arc-shaped splint 5.1, and improving the clamp fixing effect of the arc-shaped splint 5.1 on the elastic clamp ring 4, and improving the stability and sealing of the ball mouth of the balloon 3.

[0037] like Figure 3 and Figure 4 As shown, the circular baffle 6 is composed of a second pipe hoop 6.1 and two fan-shaped baffles 6.2 mounted on the second pipe hoop 6.1. The second pipe hoop 6.1 is detachably mounted on the blowing pipe 1. The structure of the second pipe hoop 6.1 is the same as that of the first pipe hoop 5. Both are composed of two arc-shaped clamping plates, and flanges are integrally formed at both ends of each arc-shaped clamping plate. The two flanges are fixedly connected by a screw and a nut. After loosening the nut, the clamping position of the second pipe hoop 6.1 can be moved along the blowing pipe 1. The two fan-shaped baffles 6.2 are respectively fixed on the two arc-shaped clamping plates. When the second pipe hoop 6.1 is clamped and fixed on the blowing pipe 1, the two fan-shaped baffles 6.2 are spliced ​​into a circular plate structure.

[0038] The two sector-shaped baffles 6.2 of the circular baffle 6 are both made of transparent plastic, so that the patient can observe the size of the balloon 3 through the circular baffle 6 during the balloon blowing training.

[0039] When the patient is training to blow a balloon, the circular baffle 6 forms a barrier between the patient's face and the balloon 3, which can prevent the fragments of the balloon 3 from hitting the patient's face after it bursts, and can effectively protect the patient's face; the above-mentioned circular baffle 6 structure can be easily disassembled and assembled, and its installation position on the blowing tube 1 can be moved, so that the patient can observe the balloon 3 conveniently.

[0040] like Figure 1 and Figure 3 As shown, the handle 7 is composed of a sleeve 7.1 that is sleeved on the blowing tube 1 and a handlebar 7.2 fixed to the outer wall of the sleeve 7.1. The inner wall of the sleeve 7.1 is fixed with a non-slip rubber layer to provide damping between the sleeve 7.1 and the blowing tube 1. A certain external force needs to be applied by hand to rotate or move the sleeve 7.1 along the axial direction of the blowing tube 1. The installation position of the handle 7 on the blowing tube 1 can be adjusted, and the distance between the handle 7 and the right end of the blowing tube 1 can be adjusted.

[0041] The handle 7 is located between the circular baffle 6 and the mouthpiece 8. The patient can hold the handle 7 by hand to control the air blowing tube 1, which is convenient for balloon blowing training.

[0042] In this embodiment, the blowing tube 1 and the annular boss 2 are both made of plastic and are integrally formed; the arc-shaped clamping plate 5.1 and flange 5.2 of the first pipe clamp 5, the second pipe clamp 6.1, and the handle 7 are all made of plastic, and the screw 5.3 and the nut 5.4 are both made of metal.

[0043] The use method and technical effects of the training device in this embodiment are as follows:

[0044] When using the device to inflate a balloon to exercise lung capacity, the nozzle of the balloon 3 is placed on the annular boss 2, and the elastic clamp ring 4 is stretched by hand to be placed on the annular boss 2. After releasing the hand, the elastic clamp ring 4 is clamped in the annular clamping groove 9 to fix the nozzle of the balloon 3 in the annular clamping groove 9. The annular clamping groove 9 can limit the elastic clamp ring 4 to prevent the elastic clamp ring 4 from shifting, thereby improving the clamping effect of the elastic clamp ring 4 on the nozzle of the balloon 3 and improving the stability and sealing of the nozzle of the balloon 3.

[0045] The two arc-shaped clamps 5.1 are clamped on the annular boss 2, and the elastic clamp ring 4 is clamped inside the two arc-shaped clamps 5.1. The nut 5.4 is tightened to fix the two corresponding flanges 5.2 together. In this way, the two arc-shaped clamps 5.1 squeeze the elastic clamp ring 4 to clamp the elastic clamp ring 4 on the annular boss 2, and the elastic clamp ring 4 clamps the ball mouth of the balloon 3 on the annular boss 2. This can increase the stability and sealing between the ball mouth of the balloon 3 and the annular boss 2, and prevent the ball mouth of the balloon 3 from falling off or leaking during balloon blowing training.

[0046] The patient holds the handle 7 to control the insufflation tube 1, and blows air into the mouthpiece 8 to inflate the balloon 3, thereby performing lung capacity training. The circular baffle 6 forms a barrier between the patient's face and the balloon 3 to prevent the balloon 3 from rupturing and causing fragments to bounce onto the patient's face.

[0047] With this training device, the balloon 3 can be fixed on the annular boss 2 at the left end of the insufflation tube 1. The patient blows air from the right end of the insufflation tube 1 to inflate the balloon 3 for lung capacity training. The elastic clamp ring 4 and the first tube hoop 5 are used to fix the nozzle of the balloon 3, which can prevent the nozzle of the balloon 3 from falling off during the balloon blowing training and prevent the balloon 3 from leaking and flying out, thereby ensuring the smooth progress of the balloon blowing training.

[0048] After disassembling the first tube hoop 5 and the elastic clamp ring 4, the balloon 3 can be taken off and replaced with a new balloon 3 during the next balloon blowing training.
