Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing the configuration of a self-respiration rehabilitation apparatus according to an embodiment of the present invention.

Referring to FIG. 1 , the self-respiratory rehabilitation apparatus 100 according to an embodiment of the present invention includes a body 110 , a mask 120 , an air conditioner 130 , a measurement unit 134 , a control unit 140 and It includes a power supply unit 150 .

In the following description, the patient is a person who performs inhalation and exhalation with respect to the self-rehabilitation apparatus 100 according to the present invention, and the user is a person who operates the self-rehabilitation apparatus 100 according to the present invention, the patient and the user may be the same person or different persons.

The main body 110 has a predetermined size and shape, and an air conditioning unit 130 , a measurement unit 134 , a control unit 140 , and a power supply unit 150 to be described later may be disposed therein.

Here, the main body 110 is preferably made of a size and shape that is easy for the general public to carry.

The mask 120 is configured to be detachable from the face of the patient using the self-rehabilitation apparatus 100 according to the present invention. The mask 120 is formed to cover the nose and mouth of the patient, and is configured not to be separated from the face during use.

An air supply hose 122 having a predetermined length and diameter is connected to the mask 120 .

In patients with tracheostomy, it can be connected to the tracheostomy tube, and a separate tube connected to the air supply hose is used.

The air supply hose 122 supplies air for the patient's breathing and allows the exhaled air to be discharged from the patient.

Here, a part of the air supply hose 122 is disposed within the body 110 , and the remaining part extends outside the body 110 . The air supply hose 122 disposed inside the body 110 has a diameter that facilitates the arrangement of the fan 132, which will be described later. In addition, the air supply hose 122 disposed outside the body 110 has a smaller diameter than the air supply hose 122 disposed inside the body 110 and is made of a flexible material to facilitate response to a change in the patient's position. It is preferable to be configured.

Here, it is preferable that a filter 124 for filtering dust and bacteria contained in the air moving the air supply hose 122 is disposed on the air supply hose 122 . In addition, although not shown in the drawings, a sputum discharge bag capable of hygienically separating and discharging the discharged sputum may be disposed.

The air conditioning unit 130 is disposed on the main body 110, supplies air to the patient through the air supply hose 122 and the mask 120, or moves the air exhaled by the patient. Here, the exhaled air is discharged to the outside through the mask 120 and the air supply hose 122 .

The air conditioning unit 130 includes a motor M, a fan 132 , and a valve 136 .

The motor M is configured to rotate forward or reverse at a predetermined number of revolutions by a control signal output from the control unit 140 to be described later.

The motor M is disposed at a predetermined position inside the body 110 .

The fan 132 has a central shaft connected to the drive shaft of the motor M to rotate forward or reverse in conjunction with the operation of the motor M, and supplies air to the patient through the air supply hose 122, or the air supply hose Exhale through (122), that is, inhale the air exhaled by the patient.

The fan 132 may be disposed on an air supply hose 122 disposed within the body 110 .

The valve 136 is opened and closed by the control unit 140 to be described later, and regulates the movement of air through the air supply hose 122 . Accordingly, the supply of air may be interrupted or the air exhaled by the patient may be interrupted by the operation of the valve 136 .

The measurement unit 134 measures the pressure and flow rate of air moving through the air supply hose 122 and outputs a corresponding signal to the control unit 140 to be described later. That is, the measurement unit 134 may measure a flow rate, pressure, and a change period of the flow rate and pressure of the air when the patient inhales or when the patient exhales. The measurement result of the measurement unit 134 may be used as data for determining the patient's breathing ability.

The control unit 140 measures the patient's maximum respiration volume for a predetermined time, the maximum air pressure during inspiration and exhalation, and the inspiratory muscle endurance by the signal output from the measurement unit 134 .

At this time, when measuring inspiratory muscle endurance, it is expressed as a pressure time unit (PTU) calculated by multiplying the inspiratory muscle pressure from the functional residual volume of the lung to the total lung volume by the time.

2 is a graph showing intake port endurance.

The lower area of the line shown in FIG. 2 (hatched) represents the inspiratory muscle endurance.

The controller 140 compares the patient's maximum respiration amount and the maximum pressure of air during inspiration and exhalation with a reference value for determining the patient's health state, determines whether the patient is in a normal state or a state requiring breathing training, and then informs the user.

Here, the patient's maximum respiration rate is a flow rate when the patient exhales after maximally inhaling, and may be expressed as a cough flow rate.

In addition, the static inspiratory muscle oral pressure, which represents the pressure of the inhaled air at the time of maximal inspiration, _{is defined as the pressure (cmH 2} O) measured at the time of maximal inspiration in the state of the functional residual volume of the lung, and represents the pressure of the exhaled air during exhalation. Static expiratory oral pressure is defined as the pressure measured during exhalation at full lung volume (cmH ₂ O).

Therefore, static inspiratory muscle oral pressure and static expiratory muscle oral pressure can represent the respiratory muscle strength of the patient.

And inspiratory muscle endurance measurement is expressed in the area calculated by multiplying the inspiratory muscle pressure by time from the functional residual volume of the lung to the total lung volume, that is, the pressure time unit (PTU).

Inspiratory muscle endurance is reported to have a more significant relationship with mortality in chronic obstructive pulmonary disease than simple inspiratory maximal pressure, so it is a necessary indicator for predicting acute exacerbation.

In addition, the control unit 140 may perform a respiratory treatment in which the sputum is discharged by inducing coughing as performed by the self-respiratory rehabilitation apparatus according to the prior art.

Details of the determination of the controller 140 and the breathing training according thereto will be described later.

3 is a diagram showing an example of the configuration of a control unit used in the present invention.

Referring to FIG. 3 , the control unit 140 includes a key input unit SW and a display unit 146 .

The key input unit SW is disposed on the outer circumferential surface of the main body 110 and operated by the user, a power switch SW1, a breathing training selection key SW2, a cough induction selection key SW3, and an intake motor setting key SW4 ) and an exhalation motor setting key (SW5).

The power switch SW1 is operated by the user to intermittently supply power from the power supply unit 150 to be described later.

The breathing training selection key SW2 is a key for performing breathing training to improve the patient's breathing ability.

Respiratory training is a method of improving the muscular strength of the respiratory muscles by repeatedly inhaling or exhaling a predetermined amount from the patient.

The cough induction selection key SW3 is a key for inducing coughing from a patient to select a respiratory treatment.

Cough induction is a method in which the patient's lungs are expanded by supplying air to the patient, and then exhaled so that the patient's lungs are contracted a plurality of times, and the patient's sputum is discharged.

The intake motor setting key SW4 adjusts the degree of operation of the motor M when supplying air to the patient.

The exhalation motor setting key (SW5) adjusts the degree of operation of the motor (M) during exhalation of the patient.

The intake motor setting key SW4 and the exhalation motor setting key SW5 may include a '▲' type up/down key and a '▼' type down key, respectively.

Here, the operation amount of the motor set by the intake motor setting key SW4 and the exhalation motor setting key SW5 may be notified to the patient through the display unit 146 .

The display unit 146 displays and informs the patient and the user of the measurement value measured by the measurement unit 134 , the set amount of the motor operation, and the determination result of the control unit 140 , which will be described later.

The power supply unit 150 supplies power necessary for the operation of the above-described components. The power supply unit 150 includes a rectifying unit 152 for rectifying and outputting AC power input from the outside into DC and a charging unit 154 for charging the DC power output from the rectifying unit 152 .

That is, the rectifier 152 rectifies alternating current into direct current and supplies power to components that require power. Here, the charging unit 154 may be disposed on the power supply path to charge the DC power output from the rectifying unit 152 to supply power necessary for operation even when the AC power supply is stopped. In addition, the charging unit 154 enables the use of the self-respiratory rehabilitation apparatus 100 according to the present invention even when the power supply at the location where the patient who needs respiratory treatment is located is poor.

In the present embodiment, the charging unit 154 uses a lithium polymer battery, but various types of batteries may be used according to the user's needs.

Let's look at the operation of the self-rehabilitation apparatus 100 according to the present invention.

After the user moves the self-rehabilitation apparatus 100 to a location where the patient is located, the user puts the mask 120 on the patient.

Then, the user operates the power switch SW1 of the self-rehabilitation apparatus 100 ON, so that the operation of the self-respiration rehabilitation apparatus 100 is started.

The user first measures the patient's maximum cough flow, maximum pressure during inspiration and exhalation, and inspiratory muscle endurance, and uses these to determine the patient's breathing ability.

The patient is to perform breathing as usual while wearing the mask 120 . Here, the operation of the motor M is not made.

Air is moved through the air supply hose 122 by the patient's breathing (including inhalation and exhalation), and the measurement unit 134 continuously measures the amount or pressure of the air moving through the air supply hose 122 . to measure and output the corresponding signal.

The signal output from the measurement unit 134 may be input to the control unit 140 to be described later, while being stored in a predetermined memory (not shown).

The control unit 140 measures the patient's respiration volume, respiration pressure, and respiration change period for a predetermined time by using the signal output from the measurement unit 134 . Respiratory volume, respiration pressure, and respiration change cycle may be used as reference data for judging a patient's respiration ability in respiration training, which will be described later.

The controller 140 may make the following determination according to the patient's respiration amount.

If the maximum value of the patient's respiratory flow rate is 270 L/min or less, it is determined that breathing training is necessary.

Here, the maximum value of the respiratory flow rate of the patient may be changed according to the user.

For example, when the inspiratory muscle pressure is less than the absolute standard of the age-specific maximum inspiratory muscle pressure related to inspiratory muscle weakness, it may be determined that breathing training is necessary. In addition, the static expiratory muscle oral pressure criterion may be determined to be the same as the static inspiratory muscle oral pressure.

Therefore, before using the self-rehabilitation apparatus 100 according to the present invention, it is preferable to perform the process of inputting the patient's age, and to apply the absolute reference value for each age to the training determination of the patient when evaluating the respiratory ability.

The absolute standard of maximum inspiratory muscle pressure by age is disclosed in [Table 1] below.

If the patient's inspiratory muscle pressure is less than the inspiratory muscle pressure standard described in [Table 1], it can be determined that the inspiratory muscle is weakened.

age Maximum inspiratory muscle pressure (Plmax) in cmH ₂ O male woman under 40 63 58 40 to 60 years old 55 50 61 to 80 years old 47 43 over 80 42 38

On the other hand, when the maximum value of the patient's respiratory flow rate exceeds 270 L/min, it can be determined that the patient's breathing is normal.

If it is determined that the patient needs breathing training, the control unit 140 controls the air conditioning unit 130 as follows and allows the patient to perform breathing training.

First, the control unit 140 sets a respiratory reference value according to the maximum cough flow measured by the measurement unit 134 and the maximum pressure during inspiration and exhalation.

That is, in the controller 140 , a value corresponding to a certain ratio of the maximum value of the patient's static respiratory muscle oral pressure measured by the measurement unit 134 is set as a reference value. Accordingly, an appropriate training reference value is generated according to the ability of each patient, and effective breathing training can be performed. In the present embodiment, a value corresponding to 50% of the patient's maximum static respiratory muscle oral pressure is set as a reference value, but this may be changed according to an individual patient's condition. The reference value can be set by the user.

In addition, when the patient's static respiratory muscle oral pressure is greater than a set reference value during breathing training, the controller 140 may output a predetermined warning sound through a warning unit (not shown).

The self-respiratory rehabilitation apparatus of the present invention performs breathing training as follows.

The patient inhales air while wearing the mask 120 . At this time, the air on the air supply hose 122 moves and is sucked into the patient, and the measurement unit 134 measures the amount of movement of the air through the air supply hose 122 .

Here, when the patient inhales 50% of his/her static respiratory muscle oral pressure, that is, more than a set reference value, the control unit generates a predetermined warning sound to notify the patient.

In this case, after the patient removes the mask 120 from the face, the patient exhales, that is, exhales, and repeats this operation to train the inspiratory muscles.

Conversely, when training the exhalation muscle, the patient exhales while wearing the mask. The measuring unit measures the patient's static expiratory muscle oral pressure, and generates an alarm to notify the patient when 50% or more of its static respiratory muscle oral pressure is reached. In this case, the patient removes the mask 120 from the face to inhale the air, and repeats this operation to train the exhalation muscle.

On the other hand, although the inhalation and exhalation of air can be switched by detachment of the mask 120 , in the process of detaching the mask 120 , the mask 120 may deviate from a predetermined position or air leakage may occur, In order to solve the above problems, by using the valve 136 disposed on the air supply hose 122, the valve 136 controls the movement of the air so as to keep the state wearing the mask 120 and A diversion of air intake and exhalation may be achieved.

A case in which breathing training is performed using the valve 136 will be described.

Since the setting of the reference value is the same as in the previous embodiment, a detailed description thereof will be omitted.

The patient inhales air while wearing the mask 120 . At this time, the valve maintains the closed state, the air on the air supply hose 122 moves to the patient and is sucked in, and the measuring unit 134 measures the pressure of the air supply hose 122 to measure the patient's intake amount. .

Here, when the patient inhales 50% of his or her maximum inspiratory amount, that is, more than the reference value, the control unit opens the valve 136 to release the internal negative pressure so that the patient can exhale. After a predetermined time elapses after the valve is opened, the control unit closes the valve again. When the valve closes, the patient resumes inspiratory exercise. By repeating inhalation and exhalation in this way, the patient trains the inspiratory muscles.

On the other hand, when the patient exhales while wearing the mask 120 and breathing training, the patient exhales while wearing the mask 120 . At this time, the valve maintains a closed state, the patient exhales through the air supply hose 122 , and the measurement unit 134 measures the pressure of the air supply hose 122 to measure the patient's exhalation volume.

Here, when the patient exhales more than 50% of his/her maximum expiratory volume, that is, the reference value, the control unit opens the valve 136 to release the internal pressure so that the patient can inhale. After a certain period of time, the control unit closes the valve again. When the valve closes, the patient resumes exhalation. By repeating exhalation and inhalation in this way, the patient trains the exhalation muscle.

If it is determined that the breathing power is improved by repeating the breathing training for a certain period or more, the breathing ability of the patient may be measured again by performing a process of measuring the breathing ability.

On the other hand, the self-respiratory rehabilitation apparatus according to the present invention can induce a patient's cough like a conventional self-respiration rehabilitation apparatus.

Induction of cough can be made as follows.

After the user moves the self-rehabilitation device 100 to the location where the patient is located, the patient is asked to wear the mask 120 .

Thereafter, the power switch SW1 of the self-respiratory rehabilitation apparatus 100 is operated ON, so that the operation of the self-respiratory rehabilitation apparatus 100 is started.

The user operates the cough induction selection key SW3. When the cough induction selection key SW3 is operated, the motor M rotates forward under the control of the controller 140 to supply air to the patient so that the patient's lungs are inflated.

When a predetermined time has elapsed after the air supply to the patient is made, the motor M is reversely rotated under the control of the controller 140 so that a negative pressure is formed against the lungs of the patient, so that the air inside the lungs is exhaled, and the lungs Induce coughing by contracting it, and sputum is expelled along with the cough.

The expansion and contraction of the lungs as described above are repeated a plurality of times (eg, 5 times), and cough is induced so that sputum is discharged.

As described above, the present invention allows the patient with weakened breathing ability to repeat constant inhalation and exhalation of air to improve the muscle strength of the respiratory muscles, thereby improving breathing ability, supplying air to a patient with reduced breathing ability, , by inducing exhalation, inducing coughing in the patient, so that secretions in the lungs or airways are discharged.

Although the present invention has been described with reference to the embodiment shown in the drawings, which is merely exemplary, it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible therefrom. Accordingly, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
