Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation devices, and more specifically, to a device for pulmonary function rehabilitation therapy in respiratory medicine. Background Technology

[0002] Pulmonary rehabilitation is a rehabilitation treatment method for functional impairments caused by lung diseases. It mainly helps patients improve lung function and enhance their quality of life through a series of rehabilitation training and conditioning measures.

[0003] Exercise can be achieved by adjusting breathing techniques, altering the diameter of the airway: by expanding or contracting the muscles of the chest and abdomen, the diameter of the airway can be changed, thereby affecting the speed of airflow. For example, during deep breathing, the chest cavity expands, increasing lung capacity, slowing airflow speed, and reducing resistance;

[0004] Most existing breathing exercise devices use a gas container with an elastically connected plate inside. Users blow air into the container and counteract the elastic force on the plate to adjust the force required for blowing, thus achieving the purpose of exhalation exercise.

[0005] However, in actual use, when gas flows through the container, gas and moisture from the body can adhere to the inside of the container. Furthermore, it is inconvenient to clean and disinfect the corners inside the container, which may lead to cross-infection and pose certain safety hazards. In addition, the breathing process cannot be directly observed and controlled to ensure stability, which may result in short exhalation or inhalation times and uneven force, making it impossible to perform targeted exercises. Therefore, a device for pulmonary function rehabilitation and physiotherapy in respiratory medicine is needed to solve the above problems. Summary of the Invention

[0006] In view of the problems in existing technologies, such as the inconvenience of cleaning and disinfecting the corners inside the container, which may lead to cross-infection and pose certain safety hazards, and the inability to intuitively understand and control the stability of breathing, the purpose of this invention is to provide a device for pulmonary function rehabilitation therapy in respiratory medicine.

[0011] Optionally, the movable pressure mechanism includes a movable plate that is slidably disposed inside the breathing cylinder. A first elastic component is connected to the side of the movable plate away from the breathing mask. An intermediate plate is connected to the other end of the first elastic component.

[0012] Optionally, a rotating plate is connected to one end of the first lead screw located outside the breathing cylinder, and a threaded cap is provided on the external thread of the first lead screw. The threaded cap is disposed through the side of the breathing cylinder, and the rotation control mechanism is disposed through the side of the movable plate.

[0013] Optionally, the rotation control mechanism includes a rotating shaft located inside the intermediate plate. One end of the rotating shaft outside the breathing cylinder is connected to a rotary knob, and the other end of the rotating shaft is connected to a rectangular support rod. The support rod is slidably disposed within a rotating blocking mechanism. A sliding sleeve is provided around the rotating shaft, and the sliding sleeve passes through the side of the movable plate. A second bearing is provided around the rotating shaft, and the second bearing passes through the side of the breathing cylinder. The transmission mechanism is located outside the rotating shaft.

[0014] Optionally, the rotary blocking mechanism includes a connecting seat and a buffer assembly located inside the breathing cylinder. Guide rods are connected to the sides of both the connecting seat and the buffer assembly. The guide rods are slidably disposed in the guide groove. A support cavity is opened in the connecting seat and is slidably disposed outside the support rod. A crossbar is connected to the opposite surfaces of the connecting seat and the buffer assembly. A movable ball is connected to one end of the buffer assembly. The guide groove is spiral-shaped, and the guide rod is cylindrical.

[0015] Optionally, the buffer assembly includes a piston cylinder connected to a crossbar, a piston plate slidably connected inside the piston cylinder, a moving rod connected to the side of the piston plate, one end of the moving rod located outside the piston cylinder being connected to a moving ball, a second elastic component connected to the other side of the piston plate, the second elastic component being connected inside the piston cylinder, and a rotary joint provided on one side of the piston cylinder, the rotary joint being connected to an air pipe.

[0016] Optionally, the disinfection spraying mechanism includes a connecting column located outside the connecting seat and piston cylinder, with an annular tube connected to the other end of the connecting column. The annular tube communicates with the connecting pipe, and a spray head is connected to the side of the annular tube.

[0017] Optionally, the disinfection injection mechanism includes a storage tank connected to the front of the breathing cylinder, the side of the storage tank being connected to a connecting pipe, a movable pressure plate being slidably disposed inside the storage tank, a second lead screw being connected to one side of the movable pressure plate, a threaded cylinder being externally threaded to the second lead screw, a third bearing being disposed outside the threaded cylinder, the third bearing being disposed through the side of the storage tank, and the movable pressure plate being rectangular.

[0019] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0020] In the above scheme, when adjusting the inhalation resistance, simply control the rotary knob to rotate. The rotary knob will drive the rotary shaft and support rod to rotate. When the support rod rotates, it uses the support cavity to control the rotation of the connecting seat and piston cylinder. At the same time, the guide rod moves along the guide groove to control the piston cylinder and the moving ball to move to the left, thereby adjusting the gap between the moving ball and the conical surface. Simultaneously, the rotary shaft controls the rotation of the second gear through the first gear. The second gear controls the rotation of the threaded cylinder through the first transmission wheel, belt, and second transmission wheel. When the threaded cylinder rotates, it controls the movement of the second lead screw and the moving pressure plate. The moving pressure plate squeezes the disinfectant in the storage tank. The disinfectant is sprayed into the breathing cylinder through the connecting pipe, ring pipe, and nozzle. Adjusting the gas flow channel during inhalation requires using different inhalation strengths for practice, making the practice more flexible. Furthermore, the process of adjusting the airflow channel can automatically disinfect the inside of the breathing cylinder, avoiding cross-infection caused by moisture and gas accumulating inside the breathing cylinder during breathing.

[0021] By setting up a rotary control mechanism and a one-way valve, the rotation of the first lead screw can be used to adjust the position of the middle plate in the breathing cylinder and the position of the movable plate when the rotating plate rotates. When blowing air, more force is required to push the movable plate to the corresponding position, thus adjusting the resistance of the blowing exercise. When inhaling, the outside air passes through the one-way valve and the inlet tube into the breathing cylinder, and inhalation exercises can be performed at this time. Both inhalation and exhalation exercises can be adjusted, and inhalation and exhalation exercises can be performed continuously.

[0022] By incorporating a buffer assembly and a mercury column assembly, the gas flow impacts the moving sphere as it passes through the gap between the conical section and the moving sphere. The movement of the moving sphere controls the sliding of the moving rod and piston plate within the piston cylinder. The gas within the piston cylinder is connected to the mercury column assembly, allowing for an increase or decrease in the amount of gas within the mercury column. The position of the mercury column within the mercury column assembly indicates the amplitude of the moving sphere's sway, facilitating observation of the stability of the gas flow during exhalation and inhalation. Users can control the intensity of exhalation and inhalation based on the measurements from the mercury column assembly, enabling more precise training of stability during lung rehabilitation exercises.

[0053] like Figures 1 to 10 As shown, this embodiment of the invention provides a device for pulmonary function rehabilitation therapy in respiratory medicine, including a breathing cylinder 1. A connector 3 is connected to the side of the breathing cylinder 1, and a breathing mask 4 is movably installed in the connector 3. An inlet pipe 5 is connected through the breathing cylinder 1, and a one-way valve 6 is provided outside the inlet pipe 5. A movable pressure mechanism 7 is provided through the side of the breathing cylinder 1 and is slidably disposed inside the breathing cylinder 1. The same rotary control mechanism 8 is provided through the side of the breathing cylinder 1 and the movable pressure mechanism 7. A rotary blocking mechanism 9 is slidably disposed outside the rotary control mechanism 8. Two guide grooves 16 are opened inside the breathing cylinder 1, and the rotary blocking mechanism 9 is slidably disposed in the guide grooves 16. A trachea 10 is connected to the side of the rotary blocking mechanism 9 and is disposed through the back of the breathing cylinder 1. One end of the trachea 10 located outside the breathing cylinder 1 is connected to a mercury column assembly 11 for observing gas changes. The mercury column assembly 11 is connected to the back of the breathing cylinder 1.

[0054] The side of the rotary blocking mechanism 9 is connected to a disinfection spraying mechanism 12. The front of the disinfection spraying mechanism 12 is connected to a connecting pipe 13 that passes through the front of the breathing cylinder 1. The other end of the connecting pipe 13 is connected to a disinfection injection mechanism 14. The disinfection injection mechanism 14 is connected to the front of the breathing cylinder 1. The side of the rotary control mechanism 8 is provided with a transmission mechanism 15 connected to the side of the breathing cylinder 1. The transmission mechanism 15 is connected to the disinfection injection mechanism 14.

[0055] When adjusting the intake resistance, simply rotate the knob 83. The knob 83 will drive the rotating shaft 81 and the support rod 85 to rotate. When the support rod 85 rotates, it controls the rotation of the connecting seat 91 and the piston cylinder 941 through the support cavity 92. At the same time, the guide rod 96 moves along the guide groove 16, controlling the piston cylinder 941 and the moving ball 95 to move to the left, thus adjusting the gap between the moving ball 95 and the conical surface. Simultaneously, the rotating shaft 81 controls the rotation of the second gear 152 through the first gear 151. The second gear 152, through the first transmission wheel 155, belt 156, and second... The drive wheel 157 controls the rotation of the threaded cylinder 144. When the threaded cylinder 144 rotates, it controls the movement of the second lead screw 143 and the moving pressure plate 142. The moving pressure plate 142 squeezes the disinfectant in the storage tank 141. The disinfectant is sprayed into the breathing cylinder 1 through the connecting pipe 13, the annular pipe 122 and the nozzle 123. The gas flow channel is adjusted during inhalation. Different inhalation forces are required for practice, making the practice more flexible. During the airflow channel adjustment process, the inside of the breathing cylinder 1 can be automatically disinfected, avoiding cross-infection caused by moisture and gas accumulating in the breathing cylinder 1 during breathing.

[0056] The breathing cylinder 1 has a non-slip grip strap 2 on its side, and the left end of the inner wall of the breathing cylinder 1 is tapered.

[0057] The non-slip grip strap 2 provides better hand grip comfort and anti-slip effect during use, and can be operated by one person with both hands during the exercise process;

[0058] The movable pressure mechanism 7 includes a movable plate 71 that is slidably disposed inside the breathing cylinder 1. A first elastic component 72 is connected to the side of the movable plate 71 away from the breathing mask 4. An intermediate plate 73 is connected to the other end of the first elastic component 72. Two first bearings 74 are provided on the other side of the intermediate plate 73. A first lead screw 75 is provided inside the first bearing 74.

[0059] The first lead screw 75 is connected to a rotating plate 77 at one end outside the breathing cylinder 1. The first lead screw 75 has a threaded cap 76 on its external thread. The threaded cap 76 is disposed through the side of the breathing cylinder 1. The rotation control mechanism 8 is disposed through the side of the movable plate 71.

[0060] The intermediate plate 73 is controlled by the rotating first lead screw 75 to move inside the breathing cylinder 1, thereby adjusting the position of the movable plate 71. The movable plate 71 is subjected to elastic force by the first elastic component 72. When exhaling, the gas acts on the movable plate 71 and needs to resist the elastic force to control the movable plate 71 to move. The force required to push the movable plate 71 to the corresponding position during exhalation is different depending on the position of the movable plate 71, which increases the resistance to the exhalation process, and the degree of resistance can be flexibly adjusted.

[0061] The rotation control mechanism 8 includes a rotating shaft 81 located inside the intermediate plate 73. One end of the rotating shaft 81 outside the breathing cylinder 1 is connected to a rotary knob 83, and the other end of the rotating shaft 81 is connected to a rectangular support rod 85. The support rod 85 is slidably disposed within the rotating blocking mechanism 9. A sliding sleeve 84 is provided around the rotating shaft 81, and the sliding sleeve 84 passes through the side of the movable plate 71. A second bearing 82 is provided around the rotating shaft 81, and the second bearing 82 passes through the side of the breathing cylinder 1. The transmission mechanism 15 is disposed outside the rotating shaft 81.

[0062] By setting a one-way valve 6, the rotation of the rotating plate 77, along with the rotation of the first lead screw 75, can adjust the position of the intermediate plate 73 within the breathing cylinder 1 and the position of the movable plate 71. When blowing air, greater force is required to push the movable plate 71 to the corresponding position, thus adjusting the resistance of the blowing exercise. During inhalation exercise, external air passes through the one-way valve 6 and the inlet pipe 5 into the breathing cylinder 1, allowing for inhalation exercise. Both inhalation and exhalation exercises can be adjusted, and continuous inhalation and exhalation exercises can be performed.

[0063] The sliding sleeve 84 ensures that the rotating shaft 81 can rotate smoothly without obstructing the sliding of the movable plate 71.

[0064] The rotary blocking mechanism 9 includes a connecting seat 91 and a buffer assembly 94 located inside the breathing cylinder 1. Guide rods 96 are connected to the sides of both the connecting seat 91 and the buffer assembly 94. The guide rods 96 are slidably disposed in the guide groove 16. A support cavity 92 is provided in the connecting seat 91. The support cavity 92 is slidably disposed outside the support rod 85. A crossbar 93 is connected to the opposite surfaces of the connecting seat 91 and the buffer assembly 94. A movable ball 95 is connected to one end of the buffer assembly 94. The guide groove 16 is spiral-shaped, and the guide rod 96 is cylindrical.

[0065] The guide rod 96 and guide groove 16 are used. When the guide rod 96 rotates, it will cause the connecting seat 91 and piston cylinder 941 to rotate horizontally. The horizontal position of the moving ball 95 is adjusted by rotation control. The support cavity 92 cooperates with the support rod 85. The rectangular support rod 85 can smoothly control the rotation of the support cavity 92 and the connecting seat 91. During the rotation, the support cavity 92 and the connecting seat 91 can slide on the surface of the support rod 85. The connecting pipe 13 and the air pipe 10 are both made of flexible tubing, which can ensure that the air pipe 10 and the connecting pipe 13 can still maintain the connection with the outside when the rotary blocking mechanism 9 rotates.

[0066] The buffer assembly 94 includes a piston cylinder 941 connected to a crossbar 93. A piston plate 942 is slidably connected inside the piston cylinder 941. A moving rod 943 is connected to the side of the piston plate 942. One end of the moving rod 943 located outside the piston cylinder 941 is connected to a moving ball 95. A second elastic assembly 944 is connected to the other side of the piston plate 942. The second elastic assembly 944 is connected inside the piston cylinder 941. A rotary joint 945 is provided on one side of the piston cylinder 941. The rotary joint 945 is connected to the air pipe 10.

[0067] The rotary joint 945 ensures that the connection between the piston cylinder 941 and the air pipe 10 is maintained when the piston cylinder 941 rotates. The gas changes inside the piston cylinder 941 can be reflected by the mercury column assembly 11, which makes it easy to determine whether the moving ball 95 is stable.

[0068] When the moving ball 95 shakes, it controls the piston plate 942 to move. When the piston plate 942 moves, it squeezes the gas in the piston cylinder 941, or draws gas into the piston cylinder 941 through the air pipe 10. The elastic force applied to the piston plate 942 by the second elastic component 944 will keep the piston plate 942 and the moving ball 95 in a relatively stable state.

[0069] By setting up a buffer component 94 and a mercury column component 11, when the gas flows through the gap between the conical part and the moving ball 95, the gas flow will impact the moving ball 95. The movement of the moving ball 95 will control the sliding of the moving rod 943 and the piston plate 942 within the piston cylinder 941. The gas in the piston cylinder 941 is connected to the mercury column component 11, which can increase or decrease the amount of gas in the mercury column component 11. The position of the mercury column in the mercury column component 11 can be used to determine the swaying amplitude of the moving ball 95, making it convenient to observe the stability of the gas flow during the blowing and inhaling process. Users can control the force of the blowing and inhaling process based on the measurement of the mercury column component 11, and more accurately train the stability during lung rehabilitation exercises.

[0070] The disinfection spraying mechanism 12 includes a connecting column 121 located outside the connecting seat 91 and the piston cylinder 941. The other end of the connecting column 121 is connected to an annular tube 122, which is connected to the connecting tube 13. A spray nozzle 123 is connected to the side of the annular tube 122.

[0071] The disinfectant is sprayed through the ring pipe 122 and then through the nozzle 123, so that the nozzle 123 can spray the disinfectant onto the inner wall of the breathing cylinder 1 during rotation, thereby disinfecting the inside of the breathing cylinder 1.

[0072] The disinfection injection mechanism 14 includes a storage tank 141 connected to the front of the breathing cylinder 1. The side of the storage tank 141 is connected to the connecting pipe 13. A movable pressure plate 142 is slidably disposed inside the storage tank 141. A second lead screw 143 is connected to one side of the movable pressure plate 142. A threaded cylinder 144 is externally threaded to the second lead screw 143. A third bearing 145 is disposed outside the threaded cylinder 144. The third bearing 145 passes through the side of the storage tank 141. The movable pressure plate 142 is rectangular.

[0073] The movable pressure plate 142 works in conjunction with the storage tank 141. When the movable pressure plate 142 moves closer to the breathing mask 4, it will squeeze the disinfectant in the storage tank 141 to be discharged. When the threaded cylinder 144 rotates, it will use the thread action between it and the second lead screw 143 to control the second lead screw 143 and the movable pressure plate 142 to move in the horizontal direction.

[0074] The transmission mechanism 15 includes a first gear 151 disposed outside the rotary blocking mechanism 9. A second gear 152 meshes with the side of the first gear 151. A connecting shaft 153 passes through the side of the second gear 152. A fourth bearing 154 connected to the side of the breathing cylinder 1 is sleeved on the connecting shaft 153. A first transmission wheel 155 is connected to one end of the connecting shaft 153. A belt 156 is disposed outside the first transmission wheel 155. A second transmission wheel 157 is disposed inside the belt 156. The second transmission wheel 157 is connected to the disinfection injection mechanism 14.

[0075] The working process of the technical solution provided by this invention is as follows:

[0076] In use, rotating the rotary knob 83 will drive the rotating shaft 81 and the support rod 85 to rotate. At the same time, the connecting seat 91, the crossbar 93, and the piston cylinder 941 are controlled to rotate by the support rod 85. The guide rod 96 moves along the guide groove 16, which can make the connecting seat 91 and the piston cylinder 941 move to the left, and the gap between the moving ball 95 and the conical part becomes smaller. The rotating shaft 81 controls the rotation of the second gear 152 through the first gear 151. The second gear 152 controls the rotation of the threaded cylinder 144 through the first transmission wheel 155, the belt 156, and the second transmission wheel 157. When the threaded cylinder 144 rotates, it controls the movement of the second lead screw 143 and the moving pressure plate 142. The moving pressure plate 142 squeezes the disinfectant in the storage tank 141. The disinfectant is sprayed into the breathing cylinder 1 through the connecting pipe 13, the annular pipe 122, and the nozzle 123, achieving disinfection treatment inside the breathing cylinder 1 during the size adjustment of the gas channel during the inhalation process. After completion;

[0077] The user positions the breathing mask 4 at the mouth and inhales air from the breathing cylinder 1 through it. Outside air enters the breathing cylinder 1 via the one-way valve 6 and inlet tube 5. The air in the breathing cylinder 1 then enters the user's body through the gap between the movable ball 95 and the conical section. The airflow velocity impacts the movable ball 95, causing it to move and control the moving rod 943 and piston plate 942 within the piston cylinder 941. The piston plate 942's movement compresses the air through the air tube 10, causing it to circulate within the mercury column assembly 11 and the piston cylinder 941. The displayed values ​​in the mercury column assembly 11 change accordingly. By observing these values, the user can more intuitively and accurately control their inhalation speed, achieving both resistance training and stability training simultaneously. ；

[0078] When exhalation training is required, the rotating plate 77 is directly controlled to rotate. When the rotating plate 77 rotates, the middle plate 73 and the movable plate 71 are moved through the first lead screw 75 until the movable plate 71 moves to the designated position. The force required to push the movable plate 71 to the corresponding position by blowing air varies depending on the initial position of the movable plate 71. Then, the user can blow air into the breathing cylinder 1 through the breathing mask 4. The increased air pressure in the breathing cylinder 1 will squeeze the movable plate 71 to move. At the same time, the first elastic group 72 is squeezed and deformed. By controlling the movable plate 71 to move to different positions, the exhalation resistance can be adjusted, thus realizing the exhalation training process.
