DETAILED DESCRIPTION

[0026] The following is a further explanation of the present invention in conjunction with specific embodiments. Figure 1 As shown, this embodiment is a device for performing breathing training on patients, and is further suitable for pediatrics. It can adjust the resistance of the blowing training device according to the large differences in age, body shape, and development level of pediatric patients. The device includes a base 1, one end of the base 1 is connected to a mouthpiece 41 through a hose 4, and the other end is provided with an observation trachea 21.

[0027] like Figure 2 As shown, the hose 4 is connected to the observation air pipe 21 through the main air pipe 12, and air can be blown into the observation air pipe 21 when air is blown through the nozzle 41; the observation air pipe 21 is made of a transparent material, and a floating ball 3 is arranged in the observation air pipe 21; the floating ball 3 is a lightweight hollow ball, and its outer diameter is transitionally matched with the inner diameter of the observation air pipe 21, and can slide freely up and down in the observation air pipe 21; when air is blown through the nozzle 41, air can be blown to the bottom of the observation air pipe 21 through the main air pipe 12 to lift the floating ball 3; the diameter of the main air pipe 12 is smaller than the diameter of the observation air pipe 21, so that the floating ball will not fall into the main air pipe 12.

[0028] At one end of the base 1, an observation air tube 21 is provided with a door-shaped support frame 2; the two side frames of the support frame 2 can be used for grasping, and the user can grasp the two side frames of the support frame 2 with his hands to stabilize the device during training; the upper frame of the support frame 2 is connected to the observation air tube 21, and a prompt whistle 22 is provided on the upper frame; the prompt whistle 22 is connected to the observation air tube 21, and when the float ball 3 is blown to the top of the observation air tube 21, continue to blow air, and excess air will be discharged through the prompt whistle 22, and at the same time, the prompt whistle 22 will be blown to emit a prompt whistle; when the prompt whistle 22 continues to emit a whistle, it means that this blowing training remains effective; according to training needs, one blowing training needs to last for 3-5 seconds, that is, maintaining the whistle for 3-5 seconds is an effective training. By setting the prompt whistle 22, both excess air can be discharged to maintain training, and it can also be used to time and judge the training effect. It can also improve the training interest of young children and maintain their training enthusiasm.

[0029] A regulator is provided at the connection between the main air pipe 12 and the hose 4 on the base 1; the regulator includes an adjusting knob 5, and a scale line 11 is provided on the base 1 in coordination with the adjusting knob 5, such as Figure 1 and 3 As shown; the resistance corresponding to different knob positions on the scale line 11 is marked with different applicable age or body size standards, which is convenient for parents of children to choose the appropriate resistance coefficient in daily rehabilitation exercises after discharge; the adjustment knob 5 is rotatably connected to the chassis 14, the chassis 14 is fixedly arranged on the base 1, and a knob shaft 17 is arranged on the chassis, such as Figure 5 As shown; a matching turntable and groove structure are provided on the outer side surface of the knob shaft 17 and the inner side surface of the adjusting knob 5, so that the adjusting knob 5 can rotate around the knob shaft 17; a connecting end 13 is provided on the knob shaft 17, and the connecting end 13 can be connected with the bottom end of the hose 4; a connecting vent hole is provided on the chassis 14, the knob shaft 17 and the connecting end 13, which can connect the hose 4 and the main air pipe 12.

[0030] A sliding hole 18 is provided on the side wall of the knob shaft 17. In this embodiment, the angle between the two ends of the sliding hole 18 and the central axis is 180°; the sliding hole 18 is a through hole, and a connecting plate 52 is provided on the inner side of the adjusting knob 5. The connecting plate 52 cooperates with the sliding hole 18 and is provided through the sliding hole 18. Figure 8 As shown; the other end of the connecting plate 52 is fixedly connected to an umbrella shaft sleeve 53, and the umbrella shaft sleeve 53 is a cylindrical structure, wherein the axis thereof is coaxially arranged with the central axis of the adjusting knob 5.

[0031] An adjusting umbrella is provided in cooperation with the adjusting knob 5. The adjusting umbrella includes a vertically arranged umbrella shaft 6 and a frame 71 controlled by the upward and downward extension of the umbrella shaft 6. A layer of windproof cloth 7 is provided on the frame 71. Figure 3 and Figure 4 On the inner side of the umbrella sleeve 53 is provided with a spiral groove 54, as Figure 6 As shown, a sliding block 61 is provided on the side surface of the upper half of the umbrella shaft 6 . The sliding block 61 is a hemispherical structure that matches the sliding groove 54 and can slide in the sliding groove 54 .

[0032] The rotation of the umbrella shaft 6 is limited by the limit plate 16, and the limit plate 16 is fixedly connected to the chassis 14 through a plurality of support plates 15; Figure 7As shown, a through hole is provided on the limit plate 16, and the through hole cooperates with the umbrella shaft 6, so that the umbrella shaft 6 can pass through the through hole; limiting grooves are provided at both ends of the through hole, and a limiting flange 62 cooperating with the limiting groove is provided on the side of the umbrella shaft 6, and the limiting flange 62 cooperates with the limiting groove so that the umbrella shaft 6 cannot rotate around the central axis; when the adjusting knob 5 is rotated, the umbrella shaft sleeve 53 and the spiral slide groove 54 on the inner side thereof are driven to rotate together. Since the rotation of the umbrella shaft 6 is limited, when the slide groove 54 rotates, it will push the slider 61 to slide up and down, thereby driving the entire umbrella shaft 6 to move up and down.

[0033] The end of the umbrella shaft 6 is provided with a frame plate, which is a disc-shaped structure and is connected to the limit plate 16 through the frame structure; the frame structure includes a plurality of groups of frame rods 71 ​​evenly distributed around the central axis of the umbrella shaft 6, and each group of frame rods includes an upper frame rod and a lower frame rod, such as Figure 7 As shown, the top end of the upper frame rod is connected to the limit plate 16 through an axial hole structure, the bottom end of the upper frame rod and the top end of the lower frame rod are also connected to each other through the axial hole structure, and the bottom end of the lower frame rod is also connected to the frame plate through the axial hole structure; since the limit plate 16 is fixedly arranged, and the frame plate is connected to the umbrella shaft 6, it can be raised and lowered with the umbrella shaft 6. Therefore, when the umbrella shaft 6 is raised, the frame rod 71 will be driven to unfold, so that the cross-sectional area of ​​the windshield cloth 7 in the main air pipe 12 is increased, and the cross-sectional area of ​​the main air pipe 12 at the windshield cloth 7 is reduced, thereby increasing the blowing resistance; conversely, when the umbrella shaft 6 is lowered, the frame rod 71 will also shrink accordingly, so that the windshield cloth 7 is also retracted, no longer blocking the blowing, thereby reducing the blowing resistance. Fig. 9 shown.

[0034] When the present embodiment is actually used, firstly, a suitable resistance is determined according to the user's age, weight, healthy vital capacity and other data; the resistance of the blowing air can also be determined by the reference values ​​of children of various ages and weights marked on the scale lines 11 on the base 1; the blowing resistance can be adjusted by rotating the adjustment knob 5 and aligning the indicator mark 51 on the adjustment knob 5 with the target value on the scale lines 11; then, air is blown into the device through the mouthpiece 41 to move the floating ball 3 to the top of the observation trachea 21, and a whistle is emitted through the prompt whistle 22; the whistle is kept for about 3-5 seconds at a time, which can be recorded as an effective exercise. After stopping the blowing, the floating ball 3 can fall with its own weight, so that the device is reset and waits for the next blowing exercise.

[0035] The above description is only a further explanation of the present invention in combination with specific embodiments. All descriptions do not limit the protection scope of the present invention. Any changes or replacement solutions that can be easily thought of by technicians in this field within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
