In the following description, the patient is a person who performs inhalation and exhalation with respect to the self-respiratory rehabilitation apparatus 100 according to the present invention, and the user is a person who operates the self-respiratory rehabilitation apparatus 100 according to the present invention, and the patient The and user may be the same person, but they can also be different people.

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.

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 detachably attached to the face of a patient using the self-respiratory rehabilitation device 100 according to the present invention. The mask 120 is configured to cover the patient's nose and mouth, 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 from the patient to be discharged.

Here, a part of the air supply hose 122 is disposed in the main body 110, and the remaining part extends outside the main body 110. The air supply hose 122 disposed inside the main body 110 has a diameter in which the fan 132 to be described later can be easily arranged. In addition, the air supply hose 122 disposed outside the main body 110 has a smaller diameter than the air supply hose 122 disposed inside the main body 110, and is made of a flexible material, so that it is easy to respond to changes in the patient's position. It is preferable to be configured to.

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 may be disposed to hygienically separate and discharge the discharged sputum.

The air conditioning unit 130 is disposed on the main body 110 to supply air to the patient through the air supply hose 122 and the mask 120 or to move 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 control 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 rotations by a control signal output from the controller 140 to be described later.

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

The fan 132 has a central shaft connected to the drive shaft of the motor M and rotates forward or reverse in connection with the motion of the motor M, and supplies air to the patient through the air supply hose 122 or the air supply hose Exhalation, that is, the air exhaled by the patient is inhaled through (122).

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

The valve 136 is opened and closed by a 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 by the operation of the valve 136 or the air exhaled by the patient may be interrupted.

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 controller 140 to be described later. That is, the measurement unit 134 may measure the flow rate, pressure, and flow rate of air, and a cycle of change of the pressure, respectively, when the patient inhales or when the patient exhales. The measurement result of the measurement unit 134 may be used as data to determine the patient's breathing ability.

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

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

2 is a graph showing endurance of an intake port.

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

The controller 140 may compare the maximum respiratory volume of the patient and the maximum pressure of air during inhalation and exhalation with a reference value for determining the health state of the patient, determine whether the patient is in a normal state or a state that requires breathing training, and then notify the user.

Here, the maximum respiratory volume of the patient is a flow rate when the patient exhales after inhaling to the maximum, and may be expressed as a cough flow rate.

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

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

The measurement of inspiratory muscle endurance is expressed in terms of the area calculated by multiplying the inspiratory muscle pressure with 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 significant relationship with the mortality rate in chronic obstructive pulmonary disease than simple inspiratory muscle maximum pressure, and is a necessary index for predicting acute exacerbation.

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

Details of the determination of the control unit 140 and breathing training accordingly will be described later.

3 is a diagram showing an example of a 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 is operated by a user, a power switch (SW1), a breathing training selection key (SW2), a cough induction selection key (SW3), an intake motor setting key (SW4). ) And exhalation motor setting key (SW5).

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

The breathing training selection key (SW2) is a key that enables breathing training to improve the patient's breathing ability.

Breathing training is a method of improving the muscle strength of the respiratory muscles by allowing the patient to inhale or repeatedly exhale a predetermined amount from the patient.

The cough induction selection key (SW3) is a key for selecting respiratory treatment by inducing a cough from a patient.

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

The intake motor setting key SW4 increases or decreases the degree of operation of the motor M when air is supplied to the patient.

The exhalation motor setting key (SW5) increases or decreases the degree of operation of the motor (M) when the patient exhales.

The intake motor setting key SW4 and the exhalation motor setting key SW5 may each include a'▲' type of lifting key and a'▼' type of descending key.

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 a measurement value measured by the measurement unit 134, an operation setting amount of the motor, and a determination result of the control unit 140 to be described later.

The power supply unit 150 supplies power required for the operation of the above-described components. The power supply unit 150 includes a rectifier 152 that rectifies and outputs AC power input from the outside into DC, and a charging unit 154 that charges DC power output from the rectifier 152.

That is, the rectifying unit 152 rectifies AC to DC 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 situation where the patient in need of respiratory treatment is located is poor.

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

The operation of the self-respiratory rehabilitation device 100 according to the present invention will be described.

The user moves the self-respiratory rehabilitation device 100 to the location where the patient is located, and then causes the patient to wear the mask 120.

Then, the user operates the power switch (SW1) of the self-respiratory rehabilitation device 100 to ON, so that the operation of the self-respiratory rehabilitation device 100 is started.

The user first measures the patient's maximum cough flow rate, the maximum pressure during inhalation and exhalation, and the inspiratory muscle endurance, and then performs a process of determining the patient's breathing ability by using this.

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

Air is moved through the air supply hose 122 by the patient's breath (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. Measured 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, and may be stored in a predetermined memory (not shown).

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

The control unit 140 may make the following determination according to the patient's respiratory volume.

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

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

For example, when the inspiratory muscle pressure is less than the absolute standard for maximum inspiratory muscle pressure by age related to inspiratory muscle weakness, it may be determined that breathing training is necessary. And the static exhalation muscle oral pressure criterion can be determined equal to the static inspiratory muscle oral pressure.

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

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

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

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

On the other hand, if the maximum value of the patient's respiration flow rate exceeds 270 L/min, it can be determined that the patient's respiration 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 breathing reference value according to the maximum cough flow rate measured by the measurement unit 134 and the maximum pressure during inhalation and exhalation.

That is, in the control unit 140, a corresponding value of a predetermined ratio with respect to 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 standard value is generated according to the individual patient's ability, and effective breathing training can be performed. In this 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 the individual patient's condition. The setting of the reference value can be set by the user.

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

The self-respiratory rehabilitation device 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 is moved to the patient and inhaled, and the measurement unit 134 measures the amount of air movement through the air supply hose 122.

Here, when the patient inhales above 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 removing the mask 120 from the face, the patient exhales, that is, exhales, and this operation is repeatedly performed to train the inspiratory muscles.

Conversely, when training the exhalation muscles, the patient exhales while wearing a mask. The measurement unit measures the patient's static exhaled oral pressure, and when it reaches 50% or more of the static respiratory muscle oral pressure, a warning sound is generated to notify the patient. In this case, the patient removes the mask 120 from the face to inhale air, and this operation is repeatedly performed to train the exhaled muscles.

On the other hand, although the inhalation and exhalation of air may be switched by detachment of the mask 120, the mask 120 may deviate from a predetermined position or air leakage may occur in the process of detaching the mask 120, In order to solve the above problem, by using the valve 136 disposed on the air supply hose 122, the valve 136 regulates the movement of air to keep the mask 120 worn. Air intake and exhalation may be diverted.

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 a closed state, and the air on the air supply hose 122 moves to the patient and is sucked, and the measurement unit 134 measures the pressure of the air supply hose 122 to measure the amount of inhalation of the patient. .

Here, when the patient inhales 50% of his or her maximum inhalation 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 certain time elapses after the valve is opened, the control unit closes the valve again. When the valve is closed, the patient starts the inspiratory movement again. In this way, by repeatedly performing inhalation and exhalation, the patient trains the inspiratory muscles.

Meanwhile, when the patient exhales while wearing the mask 120 and performs breathing training, the patient exhales while wearing the mask 120. At this time, the valve is maintained in a closed state, the patient exhales with the air supply hose 122, and the measurement unit 134 measures the patient's expiratory volume by measuring the pressure of the air supply hose 122.

Here, when the patient exhales above 50% of his maximum expiration volume, that is, more than 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 is closed, the patient resumes exhalation. In this way, the patient trains the exhaled muscles by repeatedly exhaling and inhaling.

If it is determined that the breathing ability is improved by repeating the breathing training for more than a certain time, 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-respiratory rehabilitation apparatus.

Induction of cough can be accomplished as follows.

After the user moves the self-respiratory rehabilitation device 100 to the place where the patient is located, the patient wears the mask 120.

Thereafter, by operating the power switch (SW1) of the self-respiratory rehabilitation apparatus 100, 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 and supplies air to the patient so that the patient's lungs are inflated.

When a predetermined time elapses after the supply of air to the patient is made, the motor M is rotated in reverse by the control of the control unit 140 so that a negative pressure is formed on the lungs of the patient, thereby exhaling the air inside the lungs, and It induces coughing by allowing it to contract, thereby allowing sputum to be discharged along with the cough.

The expansion and contraction of the lungs as described above are repeated a plurality of times (for example, 5 times), and cough is induced to discharge sputum.

As described above, the present invention allows a patient with a weakened breathing ability to repeat constant air inhalation and exhalation to improve the muscle strength of the respiratory muscles, thereby improving the breathing ability, and supplying air to a patient with reduced breathing ability. , Exhalation can be induced to induce a patient's cough, so that secretions in the lungs or airways are discharged.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those of ordinary skill in the art will appreciate that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
