Description

Technical Field

[0001] The present invention relates to the technical field of rehabilitation training equipment, and more particularly to a lung function rehabilitation training device for patients in a respiratory department. Background Art

[0002] Respiratory patients experience respiratory distress due to decreased respiratory muscle strength and endurance caused by lung diseases. Integrating respiratory training equipment into their treatment can promote pulmonary rehabilitation. During rehabilitation training, patients strengthen their lung function through repeated inhalation and exhalation exercises. Respiratory training devices are a core component of pulmonary rehabilitation, and targeted training can improve muscle strength and endurance, ultimately improving ventilation and quality of life.

[0003] Respiratory trainers are widely used in postoperative rehabilitation, pulmonary rehabilitation management and other fields. Their design is mainly aimed at continuous inspiratory resistance training. Traditional respiratory trainers can only perform simple continuous inhalation or exhalation training, which can easily accelerate respiratory muscle fatigue and thus weaken the training effect. In addition, traditional trainers are continuous breathing training, while normal breathing movements are intermittent alternating deep and shallow breathing. Current training equipment is unable to perform intermittent alternating deep and shallow breathing (that is, deep and shallow breathing alternating between deep breathing stages and shallow breathing stages, that is, the two are repeated intermittently), which to a certain extent limits the application effect of respiratory trainers.

[0004] In view of this, we propose a lung function rehabilitation training device for respiratory patients. Summary of the Invention

[0007] The training apparatus further comprises a breathing switching assembly disposed between the two transverse tubes, the breathing switching assembly comprising a switching ball for switching breathing modes, a pagoda mouth being fixed on the training ball, and the switching ball being rotatably connected between the two transverse tubes;

[0008] The training ball moves from bottom to top in the vertical tube by breathing into the pagoda mouth, and the breathing rhythm is enhanced by the resistance of the training ball.

[0009] The training ball moves from top to bottom in the vertical tube, and the breathing rhythm is slowed down by relying on the gravity of the training ball to achieve a change in the exhalation rhythm.

[0011] The training ball moves from bottom to top in the vertical tube by breathing into the pagoda mouth, and the breathing rhythm is enhanced by the resistance of the training ball.

[0012] Then the horizontal tube is rotated, and the vertical tube is rotated and adjusted. By breathing into the pagoda mouth, when the training ball reaches the top arc tube of the vertical tube, the arc tube with the training ball is flipped downward, so that the training ball is always in a bottom-up movement, and the breathing rhythm is always enhanced by relying on the resistance of the training ball.

[0013] As an optional solution of the technical solution of the document of the present invention, the switching ball is provided with an air passage perpendicular to the pagoda mouth, and a baffle is fixed at one end of the air passage.

[0025] 1. The present invention quickly switches between the exhalation mode and the inhalation mode by rotating the switching ball. The training ball moves along the trajectory for one stroke for exhalation. When the switching ball is not rotated, inhalation can be achieved, and the inhalation training can be achieved by returning the training ball along the trajectory, forming a single cycle mode; the rhythm change component is switched to the exhalation mode by rotating the switching ball. At this time, when exhaling through the pagoda mouth, the training ball returns along the trajectory to achieve cyclic exhalation training. Conversely, in the inhalation mode, after the training ball returns along the trajectory, the training ball can be rotated to switch to the cyclic inhalation mode, forming a continuous cycle mode; the single cycle mode is a single exhalation / inhalation action completed by the training ball through a U-shaped trajectory, which is suitable for basic endurance training; the continuous cycle mode achieves high-intensity continuous training by switching the switching ball and the reciprocating motion of the training ball, thereby strengthening the endurance of the respiratory muscles; the intermittent deep and shallow alternation is matched with the real physiological needs, simulating the changes in respiratory load in daily activities, and improving the application effect of the breathing trainer.

[0026] 2. This invention extends the vertical tube stroke by sliding the adjustment tube, changing the length of the training ball's movement path to adapt to different lung capacity requirements. The overlap between the strip air holes and the breathing holes is adjusted to achieve refined control of the pressure gradient in the tube, covering everything from low-intensity endurance training to high-intensity interval training, meeting individualized rehabilitation plans.

[0038] The present invention will be further described in detail below with reference to the accompanying drawings.

[0039] like Figure 1-Figure 7 A pulmonary function rehabilitation training device for respiratory patients includes a transparent rhythm changing component 10. The rhythm changing component 10 includes multiple vertically arranged vertical tubes 11. The multiple vertical tubes 11 are sequentially connected by arc tubes 12 to form a closed U-shaped path. The lower ends of the first and last vertical tubes 11 are connected to a horizontal tube 13 through the arc tube 12. The horizontal tube 13 is arranged perpendicular to the vertical tube 11. A training ball 20 is arranged in the vertical tube 11. The training ball 20 moves along the multiple U-shaped tracks formed by assembling the vertical tubes 11, the arc tubes 12 and the horizontal tubes 13.

[0040] The breathing switching assembly 30 is arranged between the two horizontal pipes 13, and includes a switching ball 31 for breathing mode switching, and a tower nozzle 32 fixed on the training ball 20 and communicated with the horizontal pipes 13; the switching ball 31 is rotatably connected between the two horizontal pipes 13, and the exhalation mode and the inhalation mode are quickly switched by rotating the switching ball 31; when the switching ball 31 is not rotated, the training ball 20 is inhaled along the track in one stroke, and the inhalation training is realized by returning along the track, forming a single cycle mode;

[0041] The rhythm changing assembly 10 is switched into the exhalation mode by rotating the switching ball 31, and the training ball 20 returns along the track to realize the cyclic exhalation training by exhaling through the tower nozzle 32; conversely, when the training ball 20 returns along the track in the inhalation mode, the training ball 20 is rotated to switch into the cyclic inhalation mode, forming a continuous cycle mode.

[0042] The single cycle mode is completed by the training ball 20 completing a U-shaped track in one stroke, and is suitable for basic endurance training; the continuous cycle mode is realized by the switching ball 31 switching, and the training ball 20 reciprocating motion realizes high-intensity continuous training.

[0043] When the patient breathes through the tower nozzle 32, the training ball 20 moves from bottom to top in the stand pipe 11 under the action of air pressure, and the positive pressure resistance provided by the training ball 20 enhances the breathing rhythm.

[0044] When the training ball 20 moves to the top of the stand pipe 11 and passes through the arc-shaped pipe 12, the training ball 20 moves from top to bottom in the stand pipe 11, and the negative pressure resistance provided by the training ball 20 during inhalation under the action of gravity, thereby slowing down the breathing rhythm, realizing the exhalation rhythm change, and matching the intermittent deep and shallow alternation with the real physiological demand, simulating the respiratory load change in daily activities, and making up for the defects of the traditional training device which only trains the inhalation muscle.

[0045] As shown in Figure 1 , Figure 2 , the training ball 20 is blown from the right horizontal pipe 13 into the rightmost stand pipe 11 through the tower nozzle 32, and reaches the position of the arc-shaped pipe 12 through the stand pipe 11, and then the switching ball 31 is rotated by one hundred and eighty degrees around the axis of the horizontal pipe 13 by rotating the switching ball 31.

[0046] At this time, the training ball 20 is always in the bottom-to-top movement in the stand pipe 11 by continuous breathing on the tower nozzle 32, and the positive pressure resistance provided by the training ball 20 enhances the breathing rhythm, forming a continuous cycle in the exhalation mode and the inhalation mode.

[0047] Then the horizontal tube 13 is rotated one hundred and eighty degrees around the axis of the pagoda mouth 32. After the vertical tube 11 is rotated and adjusted, the pagoda mouth 32 is continuously breathed through, and when the training ball 20 reaches the top arc tube 12 of the vertical tube 11, the arc tube 12 with the training ball 20 is flipped downwards, so that the training ball 20 is always in a bottom-up movement, and always relies on the training ball 20 to provide positive pressure resistance during exhalation and negative pressure resistance during inhalation, thereby achieving the effect of enhancing the breathing rhythm in a single breathing cycle.

[0048] like Figure 5 、 Figure 6 As shown, the switching ball 31 is provided with an airway 311 perpendicular to the pagoda mouth 32, and a baffle 313 is fixed at one end of the airway 311. The airway 311 is connected to the pagoda mouth 32, and the pagoda mouth 32 is used to breathe in the airway 311, so that the gas passes through the baffle 313 to form a single-direction flow. The airway 311 realizes the switching of the airflow direction through the rotation of the switching ball 31.

[0049] like Figure 1-Figure 7 As shown, the ends of the two horizontal tubes 13 are respectively fixed with a first ball bowl 14 and a second ball bowl 15 adapted to the switching ball 31, so that the switching ball 31 can rotate freely between the two ball bowls. At the same time, the switching ball 31 is positioned by the clamping of the first ball bowl 14 and the second ball bowl 15 to prevent it from falling out.

[0050] A breathing hole 312 communicating with the air passage 311 is provided on one side of the switching ball 31 close to the baffle 313 , that is, the openings of the breathing hole 312 and the air passage 311 are located on both sides of the baffle 313 ;

[0051] The first ball bowl 14 is provided with a first air hole 141 and a second air hole 142 , and the second ball bowl 15 is provided with a third air hole 151 and a fourth air hole 152 . After rotation, the breathing hole 312 corresponds to the air holes.

[0052] When the breathing hole 312 corresponds to and is connected to the second air hole 142, the first air hole 141, the third air hole 151 and the fourth air hole 152 are all blocked and closed by the switching ball 31 (such as Figure 1 As shown), when the training ball 20 is placed in the right horizontal tube 13, the patient exhales into the airway 311 through the pagoda mouthpiece 32. At this time, the training ball 20 passes through the right horizontal tube 13 and enters the first vertical tube 11 from right to left (hereinafter referred to as "from right to left"), and then passes through the first arc tube 12 at the top to guide it into the second vertical tube 11. When the second vertical tube 11 is above the horizontal tube 13, the patient's exhalation intensity is slowed down by relying on the gravity (G) of the training ball 20 (as shown). Figure 1 shown);

[0053] After the training ball 20 passes through the first vertical tube 11 and enters the first arc-shaped tube 12 at the top, the switching ball 31 is rotated downward 180 degrees around the axis of the horizontal tube 13. At this time, the breathing hole 312 corresponds to and is connected with the first air hole 141. At this time, the training ball 20 is continuously exhaled, and the training ball 20 moves from bottom to top again.

[0054] When the training ball 20 moves into the left transverse tube 13 or into the vertical tube 11, the training ball 20 can be moved from the left vertical tube 11 to the right vertical tube 11 by inhaling through the pagoda mouthpiece 32, thereby achieving training during inhalation. In addition, the vertical tube 11 is turned around the axis of the transverse tube 13, thereby achieving continuous breathing training with the training ball 20 relying on negative pressure resistance.

[0055] When continuous exhalation or inhalation training is required, the breathing hole 312 corresponds to and is connected to the second air hole 142, and the first air hole 141, the third air hole 151 and the fourth air hole 152 are all blocked and closed by the switching ball 31 (such as Figure 1 As shown), exhale into the airway 311 through the pagoda mouth 32 and move the training ball 20 into the left side of the horizontal tube 13 (as shown in FIG. Figure 7 shown);

[0056] At this time, the switching ball 31 rotates 180 degrees around the axis of the pagoda mouthpiece 32. The breathing hole 312 now corresponds to and is connected to the third air hole 151. The remaining air holes are blocked by the switching ball 31. At this time, by continuously exhaling through the pagoda mouthpiece 32, the training ball 20 can be blown from the left transverse tube 13 into the right transverse tube 13.

[0057] In the inhalation mode, the switching ball 31 is rotated so that the breathing hole 312 is on the same side as the training ball 20. Then, the opening of the airway 311 is opposite to the training ball 20. At this time, you can inhale through the pagoda mouth 32.

[0058] like Figure 4 、 Figure 5 As shown, the first air hole 141, the second air hole 142, the third air hole 151, the fourth air hole 152 and the breathing hole 312 are all strip-shaped hole structures, and then by rotating the horizontal tube 13 or switching the ball 31, the overlap between the air hole and the breathing hole 312 is adjusted, and finally the opening and closing degree of the breathing hole 312 is adjusted, thereby realizing the regulation of the pressure in the tube.

[0059] like Figure 4As shown, the riser 11 includes an adjusting tube 111 and a fixed tube 112. An extension tube 113 adapted to the fixed tube 112 is fixed to one end of the adjusting tube 111 away from the arc tube 12. A plurality of sealing rings (not shown in the figure) are sleeved on the extension tube 113 to increase the sealing and connection strength with the fixed tube 112. By sliding and inserting the extension tube 113 and the fixed tube 112, the movement stroke of the training ball 20 in the riser 11 can be adjusted. By adjusting the movement stroke, the longer the stroke, the more breathing air required, and the shorter the stroke, the less breathing air required, thereby achieving adjustment of the breathing intensity.

[0060] like Figure 1 、 Figure 3 As shown, a dust ring 33 is provided on the switching ball 31 by rotation, and a mounting hole 331 is provided on the dust ring 33, and the pagoda mouth 32 passes through the mounting hole 331;

[0061] The two open ends of the dust ring 33 are respectively against the first ball bowl 14 and the second ball bowl 15. When the switching ball 31 rotates around the cross tube 13, the dust ring 33 rotates with the switching ball 31 through the action of the pagoda mouth 32. When the switching ball 31 rotates around the axis of the pagoda mouth 32, the pagoda mouth 32 rotates in the mounting hole 331, and the dust ring 33 does not move. Therefore, while ensuring the multi-directional rotation of the switching ball 31, the dust ring 33 ensures the sealing of the switching ball 31 to prevent a large amount of dust from adhering.

[0062] like Figure 1 As shown, the first ball bowl 14 and the second ball bowl 15 are rotatably arranged in the dust ring 33 through their outer edge sides, that is, the dust ring 33 is sleeved on the first ball bowl 14 and the second ball bowl 15. Therefore, while ensuring the normal rotation of the dust ring 33, it can also provide an axial restraining force to prevent the axial movement of the two cross tubes 13 from causing the switching ball 31 to disengage from the ball bowl.

[0063] like Figure 3 As shown, a handle 40 with an indicator arrow is fixed on the switching ball 31. The direction of the indicator arrow is the same as the opening direction of the airway 311, so that the direction of the airway 311 can be observed. The switching ball 31 is positioned by holding the handle 40 and then the riser 11 is supported with the help of the fingers, and the riser 11 can be flipped and adjusted by the fingers.

[0064] Working principle: Figure 1As shown, the pagoda mouthpiece 32 is connected through a hose with a mouthpiece, the airway 311 opens to the right, and the training ball 20 is only in the right side transverse tube 13. At this time, the first air hole 141 corresponds to and is connected with the breathing hole 312. At this time, the vertical tube 11 is placed above the horizontal tube 13. At this time, exhale into the right side transverse tube 13 through the pagoda mouthpiece 32. The breathing hole 312 is used to balance the air pressure in the tube. The training ball 20 is moved from bottom to top and from top to bottom in a cyclic manner through the cooperation of the vertical tube 11 and the arc tube 12 under the action of air pressure.

[0065] When the training ball 20 moves from bottom to top, the exhalation training is performed by relying on the positive pressure resistance provided by the training ball 20. When the training ball 20 moves into the left horizontal tube 13, the user inhales through the pagoda mouthpiece 32, and the training ball 20 passes through the left horizontal tube 13 and then through the plurality of vertical tubes 11, and then moves to the right horizontal tube 13.

[0066] In this breathing state, when it is necessary to always maintain the positive pressure resistance of the training ball 20 from bottom to top, the vertical tube 11 is rotated 180 degrees around the axis of the horizontal tube 13 by the finger, and the breathing hole 312 is aligned with the first air hole 141 and connected (as shown in FIG. Figure 2 shown);

[0067] When continuous exhalation or inhalation training is required, such as Figure 1 As shown, the training ball 20 is placed in the right transverse tube 13 during exhalation and in the left transverse tube 13 during inhalation. During continuous exhalation training, the training ball 20 moves from the right transverse tube 13 to the left transverse tube 13, and after reaching the left transverse tube 13, the switching ball 31 rotates around the axis of the pagoda mouth 32, and the breathing hole 312 corresponds to the third air hole 151. At this time, the opening of the airway 311 is facing the left transverse tube 13 (as shown in FIG. Figure 7 As shown), continuous exhalation training can be achieved by continuously exhaling into the transverse tube 13;

[0068] When continuing the inhalation training, adjust the training ball 20 to the left horizontal tube 13, and the breathing hole 312 corresponds to the second air hole 142, and then inhale through the pagoda mouth 32. After the training ball 20 reaches the right horizontal tube 13, rotate the switching ball 31 around the pagoda mouth 32, and make the opening of the airway 311 face the left horizontal tube 13.
