In addition, improvement of breathing type and breathing control method can be learned, so that exercise capacity can be increased and the performance ability of daily life can be increased.

In particular, the aerobic respiration and relaxation exercises are one of the indispensable treatments to increase the alveolar ventilation by enhancing the respiratory aspect and respiratory muscles through expiratory breathing and to increase the coughing function for discharging secretions in the airways. In addition, many people do not have the purpose of treating a specific disease, but they do the breathing method regularly or as needed according to their constitution and environment for the sake of mind and body.

However, in order for the user to purchase the expensive respiration training device in order to perform the breath breathing and the relaxation exercise, the user is not only economically burdened but also inconvenient to carry.

In addition, the conventional respiration training apparatus can not selectively control the pressure applied during breath breathing depending on the user's health condition, lung capacity, and the like, thereby causing inconvenience in use.

Therefore, the user can strengthen the muscles of the respiratory organs weakened by respiratory diseases due to the strong tension of the muscles of the respiratory organ through the expiration process overcoming the repulsive load.

Second, the vibrating ball portion reciprocates between the opening / closing flow path and the diaphragm disposed opposite to the vibrating ball portion to repeatedly open / close the opening / closing flow path. Thus, a compact structure in which a repulsive load is generated without a separate component for transmitting a moving force to the vibration ball can be provided, and productivity can be further improved.

Thirdly, the vibration guider part provided with the diaphragm is moved so that the interval between the diaphragm and the opening / closing flow path is selectively adjusted corresponding to the turning operation of the adjustment handle part, so that the repeated opening and closing cycle of the opening / closing flow path is set. Therefore, the repulsive load can be variedly used in consideration of the user's health condition, lung capacity, and the like, and the usability can be further improved.

1 to 5, a respiratory rehabilitation apparatus 100 according to an embodiment of the present invention includes a body 10, a flow path switching unit 20, and a load controller 30.

An air flow path 11 having both ends opened is formed in the inside of the body part 10 and air generated by the user's breathing air flows into the other end part of the air flow path 11 through one end have.

At this time, the one end 10a of the body 10 may further include a mouthpiece 40 to facilitate a user's mouth. The mouthpiece 40 may be detachably coupled to the one end 10a of the body 10 and may be integrally formed from one end 10a of the body 10, have. Accordingly, the user can repeatedly perform the inspiration or expiration breathing continuously even in a state where the mouthpiece 40 is held in the mouth. Also, the air flow can be stably guided through the dental mouthpiece 40 toward the inside of the air channel 11.

The other end portion 10b of the body portion 10 may be bent from the one end portion 10a and extend upward. Thereby, the vibrating ball portion 23 described later can be seated so as to close the seat seating portion 22, which will be described later, by its own weight.

A suction hole 12 is formed in an outer surface of one side of the body 10 so that the air flow path 11 communicates with the outside. At this time, the body part 10 may be provided with a discharge preventing part mounted on the inner surface of the air passage 11 so that the suction hole 12 can be selectively opened or closed. Here, the discharge preventing portion is operated to open the suction hole 12 when the user breathed air, and may be operated to close the suction hole 12 when breathing. Accordingly, since the user can continuously repeat the inspiratory or expiratory breathing process even when the mouthpiece 40 is in the state of door, the usability and efficiency of the respiratory rehabilitation treatment can be improved.

The flow path opening and closing part 20 is provided at the other end 10b of the body part 10 to selectively open and close the air flow path 11, The discharge of air can be selectively controlled. The flow path switching unit 20 may be detachably coupled to the other end 10b of the body 10 and may extend integrally from the other end 10b of the body 10, .

Specifically, the flow path switching unit 20 includes a mounting portion 21, a seat-sealing portion 22, a vibration ball portion 23, and a flow path extending portion 24. The mounting portion 21 may be formed to have an inner diameter corresponding to the outer diameter of the other end portion 10b of the body portion 10 so as to surround the other end portion 10b of the body portion 10. Thus, one end of the mounting portion 21 can be fitted to the other end portion 10b of the body portion 10. Of course, it is also possible to form a screw thread and a thread groove on the outer periphery of the inside of the mounting portion 21 and the other end 10b side of the body portion 10 and screw-fastened. That is, if the flow path switching unit 20 is detachably coupled to the other end 10b of the body 10, the flow path switching unit 20 may be provided in various forms.

The seating sealing portion 22 is disposed inside the mounting portion 21 so as to correspond to the opening side of the other end portion 10b of the body portion 10. One end of the seat seal 22 may be inserted into the opening of the other end 10b of the body 10 and the other end thereof may be connected to the inner surface of the seat 21 to be fixed thereto.

The vibrating ball 23 can be seated on a rim of the seat seating part 22 and an opening and closing passage 22b is formed in a central part thereof so as to face the air passage 11. At this time, the inner circumferential surface of the opening and closing passage 22b is formed with a tapered seating surface 22a so that the diameter becomes narrower toward the one side from the other side. That is, the opening area of the opening / closing passage 22b may be narrowed from the other end of the seating sealing portion 22 to one end thereof.

Here, the other opening area of the opening / closing passage 22b is set so as to exceed the maximum cross sectional area of the vibration ball 23, and the opening area of one side is set to be less than the maximum sectional area of the vibration ball 23. The vibration ball portion 23 is inserted through the other side of the opening and closing passage 22b and is seated on the seating surface 22a while being prevented from being separated from the air passage 11 side .

The air passage 11 and the opening / closing passage 22b can communicate with each other as the one end of the seat sealing part 22 is inserted into the opening side of the other end 10b of the body part 10. [ At this time, when the vibration ball portion 23 is seated on the seating surface 22a, one side of the opening / closing passage 22b may be closed to close the air passage 11. [

3, when the user breaths air through the dental mouthpiece 40, the air H that has been introduced through the suction hole 12 opened by the discharge preventing portion is supplied to the user's respirator Can flow. At this time, suction force acts on the vibration ball portion 23 toward the air channel 11 by the intake pressure to keep the open / close channel 22b in a closed state. Therefore, The air flowing toward the discharge port 11 can be blocked.

1 to 4, the vibration ball portion 23 is formed in a ball shape so that a contact area is minimized when the diaphragm 35 is rebounded to be described later, and a stable recoil is applied regardless of the exhalation pressure in any direction . Of course, if the vibrating ball 23 selectively opens and closes the opening / closing passage 22b, it may be provided in various shapes.

In addition, the vibration ball portion 23 may be formed of a metal or a resin material having a predetermined rigidity to prevent breakage when an impact is generated by the recoil action.

The flow path extending portion 24 may extend integrally from the other end of the mounting portion 21 toward the other side. In detail, the flow path extending portion 24 may be formed in a hollow cylindrical shape in which the connection flow path 24a is opened so that the opening / closing flow path 22b and a discharge flow path 31a described later communicate with each other.

At this time, the flow path extending portion 24 may extend to a predetermined length in a direction away from the mounting portion 21, and one side of the connection flow path 24a is communicated with the opening / closing flow path 22b, Is opened to communicate with the discharge passage 31a. That is, the connection passage 24a can be selectively communicated with the air passage 11 by the vibration ball portion 23 seated on the rim of the seat seal portion 22. [

Accordingly, when the vibration ball portion 23 is seated on the seating surface 22a to close the opening / closing passage 22b, a repulsive load may be generated against the breath pressure during breath breathing. Here, it is desirable to understand that the repulsive load is a pressure load which is required to cause a higher exhalation pressure than that normally required when the user exhales breath. That is, when the repulsive load is generated, the user breathed through the mouthpiece 40 more strongly than usual.

The load adjusting unit 30 includes a case 31, a vibration guider 34, and a diaphragm 35.

In detail, the case 31 is formed in a hollow cylindrical shape having a discharge passage 31a having both ends opened therein, and one end of the case 31 can be detachably coupled to the end of the flow path opening and closing part 20. At this time, the diameter of the discharge passage 31a may be set to correspond to the outer diameter of the passage extending portion 24, and one end may be coupled to cover the outer periphery of the passage extending portion 24. Of course, a structure in which a screw thread and a thread groove are formed and screwed on the inner circumference of the discharge passage 31a and the outer circumference of the passage opening and closing part 20 is also possible. That is, if the case 31 is detachably coupled to the flow path opening and closing part 20, it may be provided in various forms.

Here, the connection passage 24a may be disposed substantially inside the discharge passage 31a as the case portion 31 is deficient in the passage extension portion 24. The length of the case portion 31 from one end to the other end may be set to exceed the length of the flow path extending portion 24. The vibration guider 34 disposed inside the discharge passage 31a can be formed in a clearance space that is movable in the direction of one end and the other end of the case 31. [

Meanwhile, the vibration guider 34 may be provided in a cylindrical shape with one end thereof opened. The diaphragm 35 is detachably coupled to one end of the vibration guider 34. The vibrating guider 34 is disposed in the discharge passage 31a and has one end inserted through the opening of the connection passage 24a so that the diaphragm 35 is connected to the connection passage 24a Respectively.

Here, the vibration guider 34 includes a sidewall portion extending from the rim of the end portion to the other side so that the communication space 34a is formed therein. At this time, an outlet hole 34b is formed through the outer surface of the side wall portion so that the discharge passage 31a and the communication space 34a communicate with each other. Thus, the air introduced into the communication space 34a through the diaphragm 35 can be discharged to the discharge passage 31a through the discharge hole 34b.

It is preferable that the diaphragm 35 is disposed inside the connection passage 24a to face the seating sealing portion 22 and the outer frame portion is in close contact with the open end of the vibration guider portion 34 .

In detail, a coupling portion 34c may protrude radially outwardly from the outer edge of the diaphragm 35 at one edge of the vibration guider 34. At this time, the diaphragm 35 is clamped and fixed by the head portion of the coupling member 34d inserted into the coupling hole 35c formed on the one surface of the diaphragm 35 so as to cooperate with the coupling coupling portion 34c, (34).

The diaphragm 35 can be stably held in a state in which the diaphragm 35 is opposed to the vibration ball portion 23 in a state where the vibration guider portion 34 is screwed to the coupling member 33. [

The diaphragm 35 is preferably formed of a material such as silicon or silicone rubber which is harmless to the human body and has a predetermined elasticity. Accordingly, the vibration ball portion 23 is brought into contact with the diaphragm 35 to prevent damage due to an impact during the reaction, vibration against the exhalation pressure can be induced, disinfection with hot water is possible, and hygienic management . Of course, the diaphragm 35 may be formed of a metal or resin material having a predetermined stiffness.

Here, the vibration ball portion 23 reciprocates between the seat seal portion 22 and the diaphragm 35 due to exhalation pressure and recoil, and the air flow passage 11 and the connection passage 24a selectively communicate with each other It is preferable to repeatedly open and close the opening / closing passage 22b. In detail, a vibration contact surface 35a is formed on one surface of the diaphragm 35, which is opposed to the seat seating portion 22, to which the vibration ball portion 23 is selectively contacted.

Here, when the air E flows from the air passage 11 toward the opening / closing passage 22b by breath breathing, the vibrating bowl portion 23 seated on the seating receiving surface 22a flows into the opening / And is moved to seal the flow path 22b. At this time, the vibration ball portion 23 is moved toward the diaphragm 35 side while being separated from the seating surface 22a. The seating sealing portion 22 is opened as the vibration ball portion 23 is separated from the seating surface 22a so that the opening / closing passage 22b is opened.

In addition, the vibration ball portion 23 is in contact with the vibration contact surface 35a as the exhalation pressure is continuously applied through the opening / closing passage 22b. When the vibration ball portion 23 comes into contact with the vibration contact surface 35a and is then recoiled, a reaction force opposing the movement force due to the exhalation pressure is applied, so that the movement direction is switched to the seat seal portion 22 side have.

At this time, it is preferable that the diameter of the diaphragm 35 is set to correspond to the diameter of the connection passage 24a. Accordingly, even if the vibration ball portion 23 contacts the one side of the vibration contact surface 35a and is recoiled, the vibration ball portion 23 can be stably returned toward the seat seal portion 22 and can be seated on the seat engagement surface 22a A repulsive load can be stably generated. Also, the vibration ball portion 23 can be prevented from being separated from the inner surface of the coupling passage 24a and the outer periphery of the diaphragm 35. [ The outer diameter of the sidewall of the vibration guider 34 may be set to be substantially less than the diameter of the coupling passage 24a since the coupling portion 34c protrudes to correspond to the diameter of the diaphragm 35 .

When the vibrating ball portion 23 is moved toward the seating sealing portion 22 by the reaction force and then the opening and closing passage 22b is seated on the seating seating surface 22a, And is brought into a closed state by the vibration ball portion 23.

Here, when the user continues breathing, the vibration ball portion 23 is seated on the seating surface 22a so that the opening / closing passage 22b is hermetically sealed, and then the diaphragm 35 side And can be returned to the seat sealing portion 22 side by the recoil action.

The diaphragm 35 and the seat cushion 22 can be reciprocated between the seated sealing part 22 and the diaphragm 35 by the exhalation pressure generated by the breath of the user and the reaction force acting in reaction with the diaphragm 35 . At this time, the opening and closing of the opening / closing passage 22b is repeatedly performed by the vibration ball portion 23 in the seating sealing portion 22 during the reciprocating movement of the vibration ball portion 23, A load may be generated.

Thus, the user can perform respiratory rehabilitation training to strengthen the muscles of the respiratory organs weakened by the respiratory diseases due to the strong tension of the muscles of the respiratory organs by overcoming the repulsive load caused by the vibration ball portion 23 during the breath breath . Further, as the repulsive load is periodically generated, respiratory rehabilitation training can be stably performed such that foreign substances such as sputum attached to the inner wall of the bronchus are induced.

Accordingly, a repulsive load is generated only by the reciprocating movement of the vibration ball portion 23 due to the moving force due to the breath pressure and the recoil, without a separate component for providing a moving force to the vibration ball portion 23 so as to generate a repulsive load . Since such a device is provided with a compact structure as a volume is minimized, the productivity of the device can be further improved. Further, the flow path opening / closing unit 20 and the load adjusting unit 30 can be easily separated and assembled from the body 10, thereby improving assembling performance. So that the hygiene can be further improved.

2 to 4, it is preferable that the diaphragm 35 is formed with a vent outlet so that the air flowing into the opening and closing passage 22b flows into the discharge passage 31a. At this time, the exhalation unit includes a vibration induction hole 35b formed on one surface of the diaphragm 35 and a plurality of dispersed communication grooves 35d formed along the outer periphery of the diaphragm 35. [

In more detail, the vibration induction hole 35b is formed at least on one surface of the diaphragm 35, that is, the vibration contact surface 35a. Here, the vibration induction hole 35b guides the flow direction so that the air introduced into the connection passage 24a through the seating seal portion 22 flows into the communication space 34a during breath breathing.

At this time, the vibration induction hole 35b is preferably formed in the opposed area S corresponding to the maximum cross-sectional area of the vibration ball portion 23 that is vertically opposed. The flow direction of the air introduced into the connection passage 24a through the opening / closing passage 22b may be set according to the position of the vibration inducing hole 35b.

When the vibration induction hole 35b is disposed within the opposed area S, it can be substantially vertically opposed to one opening side of the opening / closing passage 22b, To be guided toward the diaphragm (35).

Accordingly, air caused by the exhalation pressure can stably flow through the vibration induction hole 35b while breath breathing is continued. Accordingly, the vibration ball portion 23 can be constantly moved toward the diaphragm 35 along the air flow due to the exhalation pressure, and then be recoiled. Accordingly, since the vibration ball portion 23 is not smoothly reciprocated due to vortex or the like, the occurrence of the repulsive load is minimized, so that the effect of the respiration rehabilitation treatment can be maximized and the quality of the product can be further improved.

In this case, the diameter of the vibration inducing hole 35b may be set to be less than the diameter of the vibration ball portion 23, and the vibration ball portion 23 may be formed in the seating sealing portion 22 through the vibration inducing hole 35b. And the diaphragm 35 can be prevented from being separated from each other.

In addition, the vibration induction holes 35b may be formed in a plurality of spaces, and may be formed at predetermined intervals along the rim of the opposed area S. As a result, the flow of air caused by the exhalation pressure acts on the outer surface of the vibration ball portion 23 as a whole, so that the vibration ball portion 23 stably moves from the opening / closing passage 22b toward the diaphragm 35 side .

The diaphragm 35 is provided with a plurality of distributed communicating grooves 35d in which the flow of the air flowing through the seat seals 22 is dispersed to the outside of the side wall of the vibratory guider 34, It is preferable that they are formed to be depressed away from each other. The coupling engagement portion 34c may be formed with a discharge communication groove 34f corresponding to the plurality of dispersion communication grooves 35d.

The air introduced into the connection passage 24a through the opening / closing passage 22b may be dispersed and discharged through the vibration inducing hole 35b and the dispersion communication groove 35d. The air discharged through the dispersion communicating groove 35d may flow toward the discharge passage 31a via the discharge communication groove 34f and the side wall portion of the vibration guider 34.

The diaphragm 35 is provided with a diaphragm 35 and a diaphragm 35. The diaphragm 35 communicates with the diaphragm 35 through the diaphragm 35. The diaphragm 35 communicates with the diaphragm 35 through the

diaphragm

35, 23 can be dispersed. That is, in a state in which the vibration ball portion 23 is seated on the seating surface 22a, the exhalation pressure acts on the vibration ball portion 23 through the opening / closing passage 22b.

Here, when the vibration ball portion 23 is spaced apart from the seat seal portion 22, a flow of air flowing through the opening / closing passage 22b is transmitted through the vibration inducing hole 35b and the dispersion communicating groove 35d, The exhalation pressure acting in opposition to the reaction force of the vibration ball portion 23 can be dispersed.

Therefore, the vibration ball portion 23 is exerted with an exhalation pressure acting opposed to the diaphragm 35 when the diaphragm 35 is moved toward the seat seal portion 22 by the recoil action, Lt; / RTI > Accordingly, even if the user's breathing is continued, the vibration ball portion 23 is moved to be seated on the seating surface 22a, so that the opening / closing passage 22b is instantaneously closed, so that a repulsive load can be stably generated.

Accordingly, as the exhalation pressure acting to oppose the diaphragm 35 when the diaphragm 35 recoils from the diaphragm 35 is dispersed, the diaphragm 35 is restored so that the diaphragm 35 stably seats on the seating surface 22a. As a result, repulsive load is generated through repeated opening and closing of the seat seals 22 by the vibration ball 23, so that the quality of the product can be further improved.

In addition to the training method for overcoming the repulsive load caused by the recoil of the vibration ball portion 23, respiratory rehabilitation training using various training methods can be performed through adjusting the volume of the user.

For example, when the user strongly exhales breath, the vibration ball portion 23 exceeds the reaction force generated when the pressure of the air introduced through the opening / closing passage 22b contacts the

vibration contact surface

35a, 35a can be maintained in a state in which they are in close contact with each other. At this time, as the flow area of the air flowing into the opening / closing passage 22b is reduced by the diaphragm 35, a repulsive load against the expiratory pressure is generated.

Here, the diaphragm 35 may be configured such that the vibration ball portion 23 contacts the vibrating contact surface 35a, and the diaphragm 35 is disposed in the diaphragm 35, So that it can be elastically deformed by breath breathing.

At this time, the diaphragm 35 may be elastically deformed selectively toward one side or the other side in response to the strength of the breath of the user, and vibration may be generated. Accordingly, the muscles of the user's respiratory organs can be strongly tensed by the vibration generated in the diaphragm 35, and foreign matter such as sputum attached to the inner wall of the bronchus can be induced.

Accordingly, in addition to the method of overcoming the repulsive load caused by the recoil of the vibration ball portion 23, the respiratory rehabilitation training can be performed by overcoming the repulsive load acting on the diaphragm 35, The user's interest in training can be doubled.

1 through 5, the respiratory rehabilitation apparatus 100 may include an interval gauge 34 for selectively moving the vibration guider unit 34 such that the gap between the opening / closing passage 22b and the diaphragm 35 is adjusted, It is preferable to further include a control means.

In detail, the gap adjusting means includes a control handle portion 32 and a fastening member 33. In detail, the adjustment handle portion 32 may be provided in a cylindrical shape with one end opened with a mounting communication space therein, and is rotatably coupled to the other end of the case portion 31. At this time, a hook protrusion 32b protrudes radially outward from the outer periphery of one end side of the adjustment handle portion 32, and a hooking step 31b is formed on the inner periphery of the other end side of the case portion 31 radially inwardly .

One end of the adjustment handle portion 32 can be inserted into the other end portion of the case 31 in a detent manner and the hook protrusion 32b can be hooked to the hooking step 31b . The adjustment handle 32 is rotated in the horizontal direction of the case 31 in a state in which the adjustment handle 32 is prevented from being separated from the case 31 by the hook projection 32b and the engagement step 31b, .

An air discharge hole 32c is formed in the other end of the adjustment handle 32 so as to communicate with the outside of the mounting communication space. At this time, the cross-sectional area of the air discharge hole 32c may be set so that the flow rate of the air discharged to the outside corresponds to the flow rate of the air flowing into the discharge flow passage 31a. Thus, the air flowing into the discharge passage 31a can be discharged to the outside through the air discharge hole 32c via the mounting communication space during breath breathing.

The coupling member 33 is disposed inside the discharge passage 31a and includes the head portion 33a and the extension screw portion 33b. Here, the head portion 33a may include a plurality of locking projections radially arranged in a '+' shape or the like. At this time, a plurality of engaging step portions 32a may be formed on the inner surface of the mounting communication space so that each engaging protrusion is engaged. Accordingly, when the engaging protrusion is inserted into the engaging stepped portion 32a, the engaging member 33 can be rotated in association with the rotation of the regulating handle portion 32. [

In addition, the air introduced into the discharge passage 31a may flow to the mounting communication space side through the respective engagement protrusions. The extension screw portion 33b extends from the head portion 33a to one side so as to be adjacent to the connection passage 24a and has a screw thread formed on its outer surface so that the vibration guider portion 34 is screwed.

Meanwhile, the vibration guider 34 includes a fastening hole 34e at the other end portion covering the other side of the side wall portion.

The fastening hole portion 34e is formed with a thread groove on the inner circumferential surface thereof and the threaded portion 33b passes through the fastening hole portion 34e so that the screw thread can be screwed along the thread groove. At this time, the coupling hole 34e may extend from the center of the other end of the vibration guider 34 to the inside of the communication space 34a. As a result, the area of the inner circumferential surface where the thread groove is formed increases, and the screwed state of the vibration guider 34 can be stably maintained.

Referring to FIG. 5, the load adjusting unit 30 may selectively adjust the interval between the seat seal unit 22 and the diaphragm 35 so that the repulsive load may vary. The vibration guider 34 is moved in a direction adjacent to or spaced apart from the seating sealing portion 22 corresponding to the rotation of the adjustment handle portion 32 while being disposed inside the connection passage 24a, .

At this time, the outer circumference of the diaphragm 35 and the inner surface of the connection passage 24a are formed with a projection insertion groove 35e and a rotation prevention projection 24b which are mutually formed. In detail, the projection insertion grooves 35e may be spaced apart from the diaphragm 35 at predetermined intervals. The engaging portion 34c may be formed with a projecting groove 34g corresponding to the projection insertion groove 35e.

The rotation preventing protrusion 24b may be disposed at a position corresponding to the plurality of protrusion insertion recesses 35e and protrude radially inward from the inner surface of the connection channel 24a. The rotation preventing protrusion 24b may extend from one end of the flow path extending portion 24 toward the other end and the vibration guider 34 may be slidably moved along the rotation preventing protrusion 24b .

Here, the coupling member 33 is rotated in a state of being prevented from being separated by the adjustment handle portion 32, and the vibration guider portion 34 is inserted into the projection insertion groove 35e, So that rotation is restricted. Therefore, when the fastening member 33 is rotated in conjunction with the rotation of the adjustment handle portion 32, the thread of the rotating extension screw portion 33b is moved along the screw groove of the fastening hole portion 34e, The rotational force of the adjustment handle portion 32 can be converted into the moving force of the vibration guider portion 34. [ Thus, the vibration guider 34 can be moved along the outer surface of the extension screw portion 33b in a direction adjacent to or spaced from the opening / closing passage 22b.

At this time, when the vibration guider 34 is moved in the direction adjacent to the opening / closing passage 22b, the distance between the diaphragm 35 and the opening / closing passage 22b is reduced, The cycle becomes shorter. Therefore, the number of times the opening / closing passage 22b is closed by the vibration ball portion 23 increases, so that a repulsive load against the exhalation pressure can be increased.

As the distance between the diaphragm 35 and the opening / closing passage 22b increases, the oscillating guider portion 34 moves in the reciprocating motion of the oscillating bowl portion 23 when the oscillating guider portion 34 is moved away from the opening / The cycle becomes longer. The number of times the opening / closing flow path 22b is closed by the vibration ball portion 23 is reduced, so that a repulsive load against the exhalation pressure can be reduced. That is, the repulsive load can be varied as the period of repeated opening and closing of the opening / closing passage 22b is set by reciprocating motion of the vibration ball portion 23 corresponding to the interval between the diaphragm 35 and the opening / closing passage 22b have.

Accordingly, the interval between the diaphragm 35 and the opening / closing passage 22b is selectively adjusted corresponding to the rotation operation of the adjustment handle portion 32, so that various conditions such as the user's body size, age, health condition, It is possible to use the repulsive load variablely, so that the usability can be further improved. Of course, a rotation preventing protrusion may protrude from the outer periphery of the diaphragm 35, and a protrusion insertion groove may be formed on the inner surface of the connection passage 24a.

6 is a cross-sectional view illustrating a modified example of the respiratory rehabilitation apparatus according to an embodiment of the present invention. In this modification, the basic configuration except for the flow rate regulator 136 is the same as that of the above-described embodiment, so a detailed description of the same configuration will be omitted.

As shown in FIG. 6, the load controller 130 may further include a flow controller 136 to selectively control the flow rate of air discharged from the inside of the vibration guider 134. The flow rate regulator 136 may be formed to have an inner circumferential profile corresponding to the outer circumferential profile of the vibration guider part 134 disposed inside the discharge passage 131a of the case part 131, The guider portion 134 can be inserted. The flow control unit 136 may be disposed to surround the discharge hole 134b formed on the outer surface of the vibration guider unit 134 and be rotatable about the vibration guider unit 134 .

A flow rate adjusting hole 136a may be formed in the flow rate adjusting portion 136 to correspond to the position of the discharge hole 134b and a shielding portion may be formed at the edge of the flow rate adjusting hole 136a. have. At this time, the flow rate of the air discharged from the communication space 134a inside the vibration guider part 134 to the discharge pathway 131a can be adjusted according to the size of the cross-sectional area of the shield part covering the discharge hole 134b have.

For example, when the flow rate regulator 136 is rotated so that the flow rate adjusting hole 136a and the discharge hole 134b are opposed to each other, the flow rate of the air discharged from the discharge hole 134b may be set to the maximum. In addition, when the flow rate regulator 136 is rotated to cover the discharge hole 134b by the shielding portion, the flow rate of the air discharged from the discharge hole 134b may be set to a minimum.

That is, as the cross-sectional area of the shielding portion covering the discharge hole 134b increases, the flow rate of the air discharged from the communication space 134a inside the vibration guider 134 toward the discharge passage 131a may be reduced . Accordingly, when the flow rate of the air discharged through the discharge hole 134b is reduced by the flow rate controller 136, the discharge amount of the air is lower than the inflow amount of the air during the breathing of the user, have.

In addition, the flow rate regulator 136 may extend the support extension 136b radially outwardly to penetrate the case part 131. [ The support extension portion 136b may be spaced apart from the outer circumference of the flow control portion 136 so as to be separated from the outer circumference of the support portion 136b. And an engagement adjusting hole 131c may be formed so that the end portion penetrates.

Further, an end of the support extension 136b may be provided with an extension adjuster 136c to prevent it from being separated from the engagement adjustment hole 131c. At this time, the extension adjusting portion 136c may be formed to exceed the sectional area of the latch adjusting hole 131c to prevent insertion of the latch adjusting hole 131c into the inside of the latch adjusting hole 131c. That is, the end of the support extension 136b may be prevented from being separated by the extension adjuster 136c while the end of the support extension 136b is engaged with the engagement hole 131c. In addition, the user can operate the extension adjuster 136c so that the flow adjuster 136 is rotated.

At this time, the latching hole 131c may be formed to have a predetermined length along the outer surface of the case part 131. When the support extension 136b is slid along the rim of the engagement adjustment hole 131c by the operation of the flow rate controller 136, the flow rate controller 136 adjusts the vibration guider 134 And can rotate about the center.

When the support extension 136b is unidirectionally rotated and engaged with one side edge of the latching hole 131c, the flow rate adjusting hole 136a and the discharge hole 134b are disposed to face each other, 134b may be set to the maximum. When the support extension portion 136b is rotated in the other direction and hooked on the other side of the engagement hole 131c, the discharge hole 134b is covered by the shielding portion, . That is, the length of the engagement adjusting hole 131c is set to correspond to the maximum flow rate and the minimum flow rate of the air discharged through the discharge hole 134b when the support extension 136b is hooked on both side edges, respectively Do.

1) by operating the adjustment handle (32 in FIG. 1) to adjust the rebound period of the vibration ball (23 in FIG. 1) to adjust the primary rebound load, Since the secondary rebound load can be adjusted, the desired rebound load can be precisely adjusted, which can further improve usability.
