Description

Technical Field

[0001] This invention relates to the field of nursing equipment technology, and more specifically, to a lung exhalation trainer for thoracic surgery patients. Background Technology

[0002] Thoracic surgery is a medical specialty that studies the organs within the thoracic cavity, mainly referring to the diagnosis and treatment of diseases of the esophagus, lungs, and mediastinum. Breast surgery is also included in this specialty, with pulmonary surgery and esophageal surgery being the main focus. After treating patients with lung-related diseases, these patients usually need to use training devices to help their lung function recover quickly in order to shorten the patient's recovery period.

[0003] However, patients in the recovery period of lung function usually need to maintain a certain breathing rhythm for breathing training in order to avoid breathing disorders during the training process that could lead to suffocation and interrupt the training. Most existing lung expiratory training devices cannot help patients control their breathing rate, which reduces the effectiveness of the breathing training and prolongs the patient's recovery period. Summary of the Invention

[0004] This invention provides a lung exhalation trainer for thoracic surgery patients, which solves the problem that most existing lung exhalation trainers cannot help patients control their breathing rate, thereby reducing the effectiveness of breathing training and prolonging the patient's recovery period.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A lung exhalation trainer for thoracic surgery patients includes a base compression bladder and a training component. The training component includes a cantilever mounted on the top of the compression bladder, a resistance frame rotatably mounted on the cantilever, and the resistance frame slidably mounted on the base. The resistance frame is in close contact with the base in a horizontal plane. A first motor is mounted on one side of the resistance frame via a mounting frame. The output shaft of the first motor is provided with multiple first bevel gears connected by shafts. Multiple first mounting slots are provided on the resistance frame. A rotating shaft is rotatably mounted in each of the first mounting slots. A second bevel gear is provided at one end of the rotating shaft. An adjustment plate is provided on the outside of the rotating shaft. The adjustment plate is in close contact with the first mounting slot in a horizontal direction. All second bevel gears mesh with one of the first bevel gears.

[0007] Preferably, a control component is provided on the resistance frame. The control component includes a second motor provided on one side of the resistance frame. The output shaft end of the second motor is provided with a connecting rod rotatably connected by a coupling. Multiple drums are coaxially provided on the connecting rod.

[0008] Preferably, the resistance frame has several second mounting slots, and a folding plate is provided in the second mounting slot. The folding plate has a certain elasticity. Several control plates are provided at the top of the folding plate. The control plates have through holes. All the control plates are threaded with pull ropes through the through holes. One end of the pull rope is provided with a control button. One side of the control button contacts one side of the adjacent control plate. The pull rope is wound around any of the drums.

[0009] Preferably, one end of the cantilever is provided with a rotation assembly, the rotation assembly including a fixed plate at one end of the cantilever, a slide rod passing through the fixed plate, a directional fork and a pull plate respectively at both ends of the slide rod, a locking block on one side of the directional fork, the locking block being slidably locked at one end of the cantilever, one side of the fixed plate being connected to one end of the directional fork by a spring, a pull ring being provided at the top of the resistance frame, and a directional rod coaxially disposed at one end of the resistance frame being slidably locked inside the directional fork.

[0010] Preferably, the base is provided with a guide rod and a limiting plate, the guide plate at the top of the compressed airbag is slidably engaged on the guide rod, and the guide plate on the base is slidably engaged in the limiting groove opened on the cantilever.

[0011] Preferably, a first sealing membrane and a second sealing membrane are respectively provided between the two sides of the limiting plate and the base. A first connecting block is provided at the top of the first sealing membrane, and a second connecting block is provided at the top of the second sealing membrane. Both sides of the first sealing membrane and the second sealing membrane are fixedly connected to the limiting plate and the base through airtight guide rails. Both the first connecting block and the second connecting block are connected to the bottom end of the cantilever.

[0012] Preferably, a filter screen is installed in the exhaust hole on one side of the base, and a breathing tube is connected to the bottom of the compressed air bag.

[0013] The principle and beneficial effects of this technical solution:

[0014] (1) The training component in this invention can change the equivalent wind resistance area of ​​the airflow on the movement of the resistance frame when the resistance frame moves up and down by controlling the tilt angle of the adjustment plate, thereby adjusting the resistance magnitude experienced by the patient at the same breathing frequency during breathing, and helping the patient maintain a fixed breathing frequency. When using the training component, the first motor is started first, and the output shaft of the first motor will drive the first bevel gears connected by multiple shafts at the output shaft end. Since all the first bevel gears mesh with a second bevel gear, and the second bevel gear is coaxially connected to the rotating shaft in the first mounting slot, the rotation of the first bevel gear will drive the rotating shaft to rotate. The adjustment plate coaxially set on the rotating shaft is in close contact with the first mounting slot in the horizontal direction. When the adjustment plate deviates from the horizontal direction, the equivalent wind resistance area of ​​the adjustment plate in the vertical direction changes. The smaller the equivalent area, the less resistance the patient feels during breathing. The smaller the pressure, the more likely the patient will maintain an appropriate respiratory rate during breathing. At this point, the first motor can be stopped, and the adjustment plate can be kept at a fixed angle. Connect one end of the breathing tube connected to the bottom of the compression bag to the breathing mask, and let the patient wear the mask to breathe. At this time, the compression bag will compress and expand in the vertical direction. The movement direction of the cantilever is controlled by the guide rod and guide plate. Finally, when the compression bag moves in the vertical direction, it will cause the cantilever to drive the resistance frame to move up and down. The first connecting block and the second connecting block are both connected to the bottom of the cantilever. Therefore, the first sealing membrane and the second sealing membrane will fold or stretch along the airtight guide rails on both sides, and always maintain the sealing performance of the bottom space of the resistance frame. This device can limit the patient's respiratory rate. When the patient breathes evenly, the resistance is small. Conversely, when breathing is disordered, the resistance is large, thereby improving the effect of the patient's breathing training and shortening the patient's rehabilitation period.

[0015] (2) The control component set in this invention can directly reduce the wind resistance area when the resistance frame moves, so that the device can be used by different patient groups with large differences in lung function. When using the control component, the output shaft of the second motor is driven to rotate. The drum set on the output shaft of the second motor via the connecting rod will quickly wind up the pull rope wound on it. Since the pull rope is inserted into the through hole opened on the control plate, and the control button set at one end of the pull rope is in contact with the side of the adjacent control plate, the pull rope will compress the folding plate at the bottom of the control plate through the control button during the process of being wound up by the drum, thereby changing the projected area of ​​the folding plate in the horizontal direction, and thus significantly changing the wind resistance area of ​​the resistance frame.

[0016] (3) The transposition component provided in this invention can stop the use of the training component so that the device can be adapted to the respiratory capacity of patients who are just starting to use the device for training. When using the transposition component, first pull the directional fork backward through the pull plate, then rotate the resistance frame until the directional rod at one end of the resistance frame rotates to be parallel to the directional fork. At this time, release the directional fork, and the fixed plate connected to the directional fork through the spring will spring open the directional fork under the tension of the spring, so that the slide rod where the directional fork is located slides along the fixed plate until the directional fork is stuck on the outside of the directional rod. At this time, the positioning of the resistance frame is completed. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0025] Example:

[0026] like Figures 1 to 6As shown, the present invention provides a lung exhalation trainer for thoracic surgery patient care, including a base 1, a compression airbag 11, and a training component. The training component includes a cantilever 32 disposed at the top of the compression airbag 11, a resistance frame 34 rotatably mounted on the cantilever 32, the resistance frame 34 slidably mounted on the base 1, and the resistance frame 34 being tightly fitted to the base 1 on a horizontal plane. A first motor 13 is disposed on one side of the resistance frame 34 via a mounting frame 14. The output shaft end of the first motor 13 is provided with multiple first bevel gears 12 connected by shafts. Multiple first mounting slots 36 are provided on the resistance frame 34, and a rotating shaft 23 is rotatably mounted in the first mounting slot 36. A second bevel gear 22 is disposed at one end of the rotating shaft 23, and an adjusting plate 24 is disposed on the outside of the rotating shaft 23. The adjusting plate 24 is tightly fitted to the first mounting slot 36 in the horizontal direction, and all second bevel gears 22 mesh with one first bevel gear 12.

[0027] like Figure 6 As shown, a control component is provided on the resistance frame 34. The control component includes a second motor 35 provided on one side of the resistance frame 34. The output shaft end of the second motor 35 is provided with a connecting rod 40 rotatably connected by a coupling. Multiple drums 39 are coaxially provided on the connecting rod 40.

[0028] The control component can directly reduce the wind resistance area when the resistance frame 34 moves, making the device suitable for different patient groups with large differences in lung function. When using the control component, the output shaft of the second motor 35 is driven to rotate. The drum 39 set on the output shaft of the second motor 35 via a connecting rod will quickly wind up the pull rope 18 wound on it. Since the pull rope 18 passes through the through hole 19 opened on the control plate 20, and the control button 17 set at one end of the pull rope 18 is in contact with the adjacent control plate 20, the pull rope 18 will compress the folding plate 21 at the bottom of the control plate 20 through the control button 17 during the process of being wound up by the drum 39, thereby changing the projected area of ​​the folding plate 21 in the horizontal direction, and thus significantly changing the wind resistance area of ​​the resistance frame 34.

[0029] like Figure 2 , Figure 4 and Figure 6 As shown, the resistance frame 34 has several second mounting slots 37, and a folding plate 21 is provided in the second mounting slot 37. The folding plate 21 has a certain elasticity. Several control plates 20 are provided at the top of the folding plate 21. The control plates 20 have through holes 19. All control plates 20 are threaded through the through holes 19 with pull ropes 18. One end of the pull rope 18 is provided with a control button 17. One side of the control button 17 contacts the side of the adjacent control plate 20. The pull rope 18 is wound around any drum 39.

[0030] like Figure 5 and Figure 6As shown, a shifting assembly is provided at one end of the cantilever 32. The shifting assembly includes a fixed plate 31 at one end of the cantilever 32, a slide rod 29 passing through the fixed plate 31, a directional fork 27 and a pull plate 30 at both ends of the slide rod 29, a locking block 25 on one side of the directional fork 27, the locking block 25 being slidably locked at one end of the cantilever 32, one side of the fixed plate 31 being connected to one end of the directional fork 27 by a spring 28, a pull ring 33 being provided at the top of the resistance frame 34, and a directional rod 38 coaxially provided at one end of the resistance frame 34 being slidably locked inside the directional fork 27.

[0031] The transposition assembly allows the device to stop using the training assembly, enabling the device to be adapted to the respiratory capacity of patients who are just beginning to use the device for training. When using the transposition assembly, first pull the directional fork 27 backward via the pull plate 30, then rotate the resistance frame 34 until the directional rod 38 at one end of the resistance frame 34 rotates to be parallel to the directional fork 27. At this point, release the directional fork 27, and the fixed plate 31 connected to the directional fork 27 via the spring 28 will spring open the directional fork 27 under the relaxation of the spring 28, causing the slide rod 29 where the directional fork 27 is located to slide along the fixed plate 31 until the directional fork 27 is locked on the outside of the directional rod 38. At this point, the positioning of the resistance frame 34 is completed.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, a guide rod 4 and a limiting plate 10 are provided on the base 1. The guide plate 7 provided at the top of the compressed air bag 11 is slidably locked on the guide rod 4, and the guide plate 7 provided on the base 1 is slidably locked in the limiting groove 26 opened on the cantilever 32.

[0033] like Figure 1 , Figure 2 and Figure 5 As shown, a first sealing membrane 3 and a second sealing membrane 9 are respectively provided between the two sides of the limiting plate 10 and the base 1. A first connecting block 2 is provided at the top of the first sealing membrane 3, and a second connecting block 8 is provided at the top of the second sealing membrane 9. Both sides of the first sealing membrane 3 and the second sealing membrane 9 are fixedly connected to the limiting plate 10 and the base 1 through airtight guide rails. The first connecting block 2 and the second connecting block 8 are both connected to the bottom end of the cantilever 32.

[0034] like Figure 1 and Figure 2 As shown, a filter 5 is installed in the exhaust hole on one side of the base 1, and a breathing tube 6 is connected to the bottom of the compressed air bag 11; one end of the breathing tube 6 can be used to connect a breathing mask, etc.

[0035] The specific usage and function of this embodiment are as follows:

[0036] The training component in this invention can adjust the equivalent air resistance area of ​​the resistance frame 34 as it moves up and down by controlling the tilt angle of the adjustment plate 24. This adjusts the resistance experienced by the patient at the same breathing frequency, helping the patient maintain a fixed breathing frequency. When using the training component, the first motor 13 is started first. The output shaft of the first motor 13 drives the multiple shaft-connected first bevel gears 12 at its output shaft end. Since all the first bevel gears 12 mesh with a second bevel gear 22, and the second bevel gear 22 is coaxially connected to the rotating shaft 23 in the first mounting groove 36, the rotation of the first bevel gear 12 will drive the rotating shaft 23 to rotate. The adjustment plate 24, coaxially mounted on the rotating shaft 23, is in close contact with the first mounting groove 36 in the horizontal direction. When the adjustment plate 24 deviates from the horizontal direction, the equivalent air resistance area of ​​the adjustment plate 24 in the vertical direction changes. The smaller the equivalent area, the more resistance the patient feels during breathing. The lower the resistance, the more the patient can maintain an appropriate respiratory rate during breathing. At this point, the first motor 13 can be stopped, and the adjusting plate 24 can be kept at a fixed angle. Connect one end of the breathing tube 6 connected to the bottom of the compression bag 11 to the breathing mask, and let the patient wear the mask to breathe. At this time, the compression bag 11 will compress and expand in the vertical direction. The movement direction of the cantilever 32 is controlled by the guide rod 4 and the guide plate 7. Finally, when the compression bag 11 moves in the vertical direction, it will cause the cantilever 32 to drive the resistance frame 34 to move up and down. The first connecting block 2 and the second connecting block 8 are both connected to the bottom of the cantilever 32. Therefore, the first sealing membrane 3 and the second sealing membrane 9 will fold or stretch along the airtight guide rails on both sides, and always maintain the sealing performance of the bottom space of the resistance frame 34. This device can limit the patient's respiratory rate. When the patient breathes evenly, the resistance is small. Conversely, when breathing is disordered, the resistance is large, thereby improving the effect of the patient's breathing training and shortening the patient's rehabilitation period.
