Description

Technical Field

[0001] This invention relates to a training device, and more particularly to a lung function rehabilitation training device with adjustable resistance. Background Technology

[0002] The lungs are a very important organ in the human body. For patients with lung and airway diseases, doctors will assess the severity of the disease and prescribe medication. While receiving medication, if patients can engage in appropriate and moderate physical therapy to rehabilitate their lung function, it can have a good auxiliary effect on the medication and accelerate the patient's recovery.

[0003] A search revealed a patent with publication number CN112691344A, which discloses a convenient and adjustable impedance pulmonary function rehabilitation training device for respiratory medicine. The device includes a mouthpiece, a trachea, and a piston cylinder connected in sequence. The trachea communicates with the top of the piston cylinder. Inside the piston cylinder, a moving piston and a fixed piston are arranged sequentially from top to bottom. An electromagnet is positioned at the center of the lower surface of the moving piston, and a permanent magnet is positioned at the center of the upper surface of the fixed piston. Two first exhaust holes are symmetrically arranged on both sides of the fixed piston, running vertically through it. Two second exhaust holes are symmetrically arranged on both sides of the bottom of the piston cylinder. A vertical screw is also positioned at the center of the bottom of the fixed piston. The lower end of the screw passes through a threaded sleeve at the bottom of the piston cylinder and extends out of the piston cylinder. The screw is threadedly engaged with the threaded sleeve, and an adjustment disc is also provided at the lower end of the screw.

[0004] In the training process described above, once the electromagnet moves to contact the permanent magnet, a training phase is completed, making it difficult to continue continuous blowing exercises, resulting in poor blowing exercise effects. Summary of the Invention

[0005] In view of this, the object of the present invention is to provide a pulmonary function rehabilitation training device that enables continuous blowing exercises and has adjustable resistance.

[0006] The technical solution is as follows: an adjustable resistance pulmonary function rehabilitation training device, comprising a base, a connecting cylinder, a pneumatic block, an air blowing tube, an air inlet tube, a ventilation tube, a resistance adjustment mechanism, and a support mechanism. The connecting cylinder is connected to the top of the base, and the pneumatic block is slidably connected inside the connecting cylinder. The air inlet tube is snapped onto the connecting cylinder, the lower part of the connecting cylinder is connected to the air inlet tube, and the upper part of the connecting cylinder is connected to the ventilation tube, realizing the threaded engagement between the air blowing tube and the air inlet tube. A resistance adjustment mechanism is provided between the connecting cylinder and the pneumatic block, and a support mechanism for abutting the pneumatic block is provided on the connecting cylinder.

[0007] As an improvement to the above solution, the resistance adjustment mechanism includes a liquid storage frame, a screw, a connecting pipe, a liquid guide frame, a piston plate, and an inlet pipe. The liquid storage frame is connected to the connecting cylinder, and the screw is threadedly connected to the bottom of the liquid storage frame. The piston plate is slidably connected inside the liquid storage frame, and the top of the screw extends into the liquid storage frame and is rotatably connected to the piston plate. The liquid guide frame is connected to the middle of the top of the connecting cylinder, and a connecting pipe connects the top of the liquid guide frame and the liquid storage frame. A counterweight cavity is provided inside the pneumatic block, and an inlet pipe connects the inside of the liquid guide frame and the counterweight cavity.

[0008] As an improvement to the above solution, the support mechanism includes a sliding frame, a push column, and an elastic element. The sliding frame is slidably connected to the upper outer side of the connecting cylinder. At least two push columns are spaced apart at the top of the sliding frame. The push columns are slidably connected to the connecting cylinder. An elastic element is sleeved on the push column outside the connecting cylinder. The top end of the elastic element is connected to the sliding frame, and the bottom end of the elastic element is connected to the connecting cylinder.

[0009] As an improvement to the above solution, a continuous air supply mechanism is also included. The continuous air supply mechanism includes a connecting pipe, an air guide pipe, a sealing ball, a sealing plate, an extension block, and an elastic element two. The lower part of the connecting cylinder is connected to the connecting pipe, and the upper part of the connecting pipe is connected to the connecting cylinder via an air guide pipe. A sealing ball for blocking the connecting pipe is provided inside the connecting pipe. A sealing plate is slidably connected to the lower part of the connecting cylinder. The sealing plate can block the connection between the air guide pipe and the connecting cylinder. An extension block is connected to the bottom of the sealing plate. The extension block is located at the movement trajectory of the pneumatic block. An elastic element two is connected between the sealing plate and the connecting cylinder.

[0010] As an improvement to the above solution, a limiting ring is also included, wherein the lower inner part of the connecting tube is connected to a limiting ring for limiting the position of the sealing ball.

[0011] As an improvement to the above solution, a collection mechanism is also included. The collection mechanism includes a collection frame and a guide frame. The collection frame is slidably connected to the base. The guide frame is connected to the lower part of the connecting cylinder. A liquid guiding channel is provided between the bottom of the connecting cylinder and the upper part of the base.

[0012] As an improvement to the above solution, the connecting cylinder is provided with a scale to facilitate observation of the position of the screw movement.

[0013] As an improvement to the above solution, suction cups are also included, with suction cups provided at the four bottom corners of the base and the four top corners of the sliding frame.

Detailed Implementation

[0028] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0029] An adjustable resistance pulmonary function rehabilitation training device, such as Figures 1-4 As shown, the device includes a base 1, a connecting cylinder 2, a pneumatic block 21, an air blowing pipe 3, an air inlet pipe 4, a ventilation pipe 5, a resistance adjustment mechanism, and a support mechanism. The connecting cylinder 2 is connected to the top center of the base 1. The pneumatic block 21 is slidably connected inside the connecting cylinder 2. The air inlet pipe 4 is snapped onto the outer right side of the connecting cylinder 2. The lower right side of the connecting cylinder 2 is connected to the air inlet pipe 4. The upper left side of the connecting cylinder 2 is connected to the ventilation pipe 5. The air inlet pipe 4 has a threaded groove inside. The bottom outer side of the air blowing pipe 3 is threaded so that the air blowing pipe 3 can be screwed into the air inlet pipe 4 to achieve the splicing of the air blowing pipe 3 and the air inlet pipe 4. A resistance adjustment mechanism is provided between the connecting cylinder 2 and the pneumatic block 21. A support mechanism is provided on the connecting cylinder 2 to abut against the pneumatic block 21.

[0030] like Figures 2-4 As shown, the resistance adjustment mechanism includes a liquid storage frame 61, a screw 62, a connecting pipe 63, a liquid guide frame 64, a piston plate 65, and an inlet pipe 66. The liquid storage frame 61 is connected to the middle of the left side of the connecting cylinder 2. The screw 62 is threadedly connected to the bottom center of the liquid storage frame 61. A knob is provided at the bottom of the screw 62 to facilitate its rotation. The piston plate 65 is slidably connected inside the liquid storage frame 61. The top of the screw 62 extends into the liquid storage frame 61 and is connected to the piston plate 65. 5. A rotating connection is made so that the movement of the screw 62 can push the piston plate 65 to move. A liquid guide frame 64 is connected to the top middle of the connecting cylinder 2. Two connecting pipes 63 are connected between the liquid guide frame 64 and the top of the liquid storage frame 61 so that the liquid in the liquid storage frame 61 can enter the liquid guide frame 64 through the connecting pipes 63. A counterweight cavity is provided inside the pneumatic block 21. An inlet pipe 66 is connected between the liquid guide frame 64 and the inside of the counterweight cavity. The inlet pipe 66 is a flexible hose.

[0031] like Figures 2-4 As shown, the support mechanism includes a sliding frame 71, a push column 72, and an elastic element 73. The sliding frame 71 is slidably connected to the upper outer side of the connecting cylinder 2. Four push columns 72 are spaced apart inside the top of the sliding frame 71. All four push columns 72 are slidably connected to the connecting cylinder 2. An elastic element 73 is sleeved on the push column 72 outside the connecting cylinder 2. The elastic element 73 is a return spring. The top end of the elastic element 73 is connected to the sliding frame 71, and the bottom end of the elastic element 73 is connected to the connecting cylinder 2.

[0032] This device can be used when lung function training is needed. For blowing exercises, first connect the inlet pipe 4 to the blowing pipe 3 via threads. Then blow air into the blowing pipe 3. The air enters the connecting cylinder 2, compressing the lower part of the pneumatic block 21 to move upwards. As the pneumatic block 21 moves upwards, it contacts and compresses the push column 72, causing it to move upwards. The elastic element 73 is compressed, and the upward movement of the push column 72 drives the sliding frame 71 upwards until the pneumatic block 21 moves above the ventilation pipe 5. Continue blowing air, and the air will be discharged through the ventilation pipe 5, thus continuously performing blowing exercises to achieve the desired effect. When inhalation exercises are needed, the device can be inverted so that the sliding frame 71 contacts the placement surface. Figure 2 Meanwhile, the connecting cylinder 2 slides downward within the sliding frame 71, compressing the elastic element 73. Subsequently, the pneumatic block 21 moves downward under gravity until its bottom is blocked by the push column 72. At this point, the air pipe 5 is exposed, and air can then be inhaled through the blowing pipe 3. During inhalation, the pneumatic block 21 is pulled upward, thus achieving the effect of inhalation exercise. If it is necessary to increase the weight during exercise, the screw 62 can be rotated to drive the piston plate 65 upward through the thread. When the piston plate 65 moves upward, it can squeeze the liquid in the liquid storage frame 61, thereby adding the liquid into the weight cavity inside the pneumatic block 21 through the connecting pipe 63, the liquid guide frame 64, and the liquid inlet pipe 66. This adjusts the weight inside the pneumatic block 21, thereby adjusting the resistance during blowing and achieving a better training effect.

[0033] like Figures 5-7As shown, it also includes a continuous air supply mechanism, which includes a connecting pipe 81, an air guide pipe 82, a sealing ball 83, a sealing plate 84, an extension block 85, and an elastic element 86. The lower part of the connecting cylinder 2 is connected to the connecting pipe 81, and the upper part of the connecting pipe 81 is connected to the connecting cylinder 2 via the air guide pipe 82. A sealing ball 83 is disposed inside the connecting pipe 81. The sealing ball 83 can roll within the connecting pipe 81 and is used to block the connecting pipe 81. A sealing plate 84 is slidably connected to the lower part of the connecting cylinder 2. The sealing plate 84 can block the connection between the air guide pipe 82 and the connecting cylinder 2. An extension block 85 is connected to the bottom of the sealing plate 84. The extension block 85 is located at the movement trajectory of the pneumatic block 21 so that the movement of the pneumatic block 21 can contact the extension block 85 and drive the extension block 85 to move. An elastic element 2 86, which is a connecting spring, is connected between the sealing plate 84 and the connecting cylinder 2.

[0034] like Figure 7 As shown, it also includes a limiting ring 811. The lower inner part of the connecting pipe 81 is connected to the limiting ring 811. The limiting ring 811 is used to limit the blocking ball 83 and prevent the blocking ball 83 from moving out of the connecting pipe 81.

[0035] In the initial state, the pneumatic block 21 presses down on the extension block 85, and the elastic element 86 is in a stretched state. During the blowing training, the pneumatic block 21 moves upward and no longer presses down on the extension block 85. At this time, under the action of the elastic element 86, the sealing plate 84 moves upward and can block the extension of the air guide tube 82 and the connecting tube 2, so it will not hinder the operation of the blowing training. During the inhalation training, after the device is inverted, the sealing ball 83 slides down to the end of the connecting tube 81 under the action of gravity. At this time, a flow channel is formed between the air guide tube 82 and the connecting tube 81. Then, during the inhalation, the pneumatic block 21 is driven to move upward. When block 21 moves upward, the upward movement of the starting block can contact and squeeze the extension block 85, thereby driving the sealing plate 84 to move. The elastic element 86 is compressed. After the sealing plate 84 moves, the two ends of the flow channel are connected to the inside of the connecting cylinder 2 on the upper and lower sides of the pneumatic block 21, respectively. At this time, if you continue to inhale, you can draw in the gas inside the connecting cylinder 2 above the pneumatic block 21 through the flow channel. The gas inside the connecting cylinder 2 above the pneumatic block 21 enters through the air pipe 5, so that you can continuously inhale gas to achieve continuous inhalation exercise.

[0036] like Figure 8 and Figure 9As shown, it also includes a collection mechanism, which includes a collection frame 91 and a guide frame 92. The collection frame 91 is slidably connected to the base 1, and the guide frame 92 is connected to the lower part of the connecting cylinder 2. A liquid guiding channel 93 is provided between the bottom of the connecting cylinder 2 and the upper part of the base 1. The liquid guiding channel 93 connects the middle of the collection frame 91 and the collection frame 91 so that the water in the guide frame 92 can flow into the collection frame 91 for collection. A one-way valve is provided in the liquid guiding channel 93.

[0037] During the blowing training, the air in the mouth carries a lot of moisture into the connecting tube 2. After entering the connecting tube 2, the moisture easily adheres to the inner wall of the connecting tube 2 and forms water droplets. When the pneumatic block 21 moves downward, it can scrape the water droplets on the inner wall of the connecting tube 2 to the guide frame 92, and then guide them to the collection frame 91 through the guide frame 92 and the liquid channel 93, thereby collecting the water droplets.

[0038] like Figure 10 As shown, a scale 10 is provided on the outer left side of the connecting cylinder 2. When the screw 62 is rotated, the scale 10 aligned with the bottom end of the screw 62 can be used to determine how much liquid has been added to the pneumatic block 21, thereby controlling the counterweight.

[0039] like Figure 10 As shown, it also includes suction cups 11. Suction cups 11 are provided at the four bottom corners of the base 1 and the four top corners of the sliding frame 71. When the device is placed, it can be attracted to the placement surface by the suction cups 11, making the device more stable when placed.

[0040] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
