Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to asthma.
Excretion of the patient's sputum (referred to herein as "sputum")
The present invention relates to a sputum facilitating device for treating asthma, which is a medical device for prompting the patient.

2. Description of the Related Art Although there are not a few asthma patients today, no solid treatment method for asthma has yet been found. Therefore, as a method of treating asthma, symptomatic treatments such as treatment for relieving urgency or relieving symptoms or treatment for relieving or suppressing symptoms are currently performed in order to ease seizures.

There are two types of asthma, allergic and infectious. Among them, infectious asthma has the property that a large amount of viscous sputum is involved. For infectious asthma,
In addition to causing infection and irritation, the bronchi can be thinned, and the sputum produced can block the airways, further increasing asthma attacks. Therefore, in order to prevent seizures caused by obstruction of the respiratory tract by sputum, it is necessary to take medicines properly and to have a habit of discharging sputum in the morning and at night.

[0004] Conventionally, as a sputum method for discharging sputum in the morning and at night, a chest wall vibration method and a body position sputum method are known. Of these, the chest wall sputum method is a method in which the lungs are vibrated to release sputum adhering to the bronchi, and the postural sputum method is a method in which the body is inclined and sputum is discharged from the lungs. Also,
Before performing these expectoration methods, a drug (expectorant) that promotes expectoration is usually taken. Such a drug is effective in dissolving sputum, facilitating the opening of the respiratory tract and relieving seizures. Specific examples include revelbon (bisorvon) and onoprose. In addition, if the sputum cannot be successfully excreted, the patient may have to take infusions or take steroids.

[0005]

However, the above-mentioned conventional expectoration method has a problem in that the patient has to be burdened by the troublesome procedure because the method has to be performed in a complicated procedure.

[0006] In addition, in order to facilitate the discharge of sputum, it is necessary to take a drug such as the above-mentioned level bon. However, it is basically desirable to avoid administering drugs. In particular, by taking infusions and steroids,
Since side effects will occur, it is desirable not to use these frequently.

[0007] Therefore, an object of the present invention is to make it possible for an asthmatic patient to easily excrete sputum and to minimize the use of drugs.

The movable contact S1s of the switch S1 is closed to the fixed contact S1a side by the operation of the person using the expectoration promoting device 1, and the movable contact S2s of the switch S2 is closed.
Is closed to the fixed contact S2a side, a voltage from the AC power supply 12 is applied between the terminals D1a and D1b of the diode bridge circuit 15. The current at this time is the variable resistance CR
The size is adjusted by one. When such a voltage is applied, the current is rectified by the action of the diode bridge 15, and full-wave rectification is performed. Further, the capacitor C
By this, it is smoothed and becomes a DC voltage. This DC voltage is applied to the linear IC 14 via the input terminals 14a and 14b. In the LSI 13, a voltage is applied by a DC power supply DC. The current generated at this time is determined by moving the movable contact S3s of the switch S3 to the fixed contact S3.
By connecting to any one of 3a, S3b, S3c, and S3d, a desired double stimulus amplitude is given to a low-frequency waveform, and the amplitude is adjusted to a desired amplitude by the variable resistor CR2. This current is supplied to the linear I / Os connected to the output terminals 13b, 13c and 13d of the LSI 13, respectively.

The current flowing between R1b and R1b is transformed by the high-voltage transformer TR1 into a low-frequency current, which is a high voltage of 9 kV at the maximum, and is supplied to the secondary side. Secondary side TR1 of high voltage transformer TR1
When the reed switch S4 in the waveform conversion circuit 17 is closed after the low-frequency current is supplied to c, the waveform conversion circuit 17
Thus, the waveform of the low-frequency current is converted into a desired intermittent low-frequency current. The intermittent low-frequency current at this time may be, for example, an intermittent current or half-wave rectification.

The low-frequency current whose waveform has been converted by the waveform conversion circuit 17 is supplied from one end 17a of the waveform conversion circuit 17 to the conductor 21 of the large current cloth 20 via the high-voltage resistor R1. As shown in FIG. 3, the large current-carrying cloth 20 is laid on a bed B or the like used by the patient M. Here, since the large current-carrying cloth 20 is covered with the insulating material, the conductor 21 does not directly contact the human body, so that the low-frequency current does not directly enter the human body. However, since the conductor 31 is supplied with the intermittent high-voltage low-frequency current, the action of the intermittent high-voltage low-frequency current induces an induced electromotive force in the human body across the insulating material. Occurs. With this induced electromotive force, an induced minute current flows through the human body.

Conventionally, a potential therapy device, a low-frequency therapy device and the like are known as a therapy device for passing a low-frequency current through a human body.
In each of these cases, the conductor was brought into contact with the human body, and a low-frequency current was directly supplied from the conductor to the human body. For this reason, in order to prevent electric shock from occurring between the conductor and the human body, the conductor requires moisture.
In this regard, in the sputum accelerating device 1 according to the present invention, the conductor 21 does not come into direct contact with the human body, so that no electric shock occurs. Therefore, it is not necessary to immerse the conductor 21 or the large current-carrying cloth 20 in water, that is, a dry-type conductor can be used. However, it is necessary to apply a high voltage to generate an induced microcurrent in the human body. However, although a high voltage is applied, the current is a very small current in the unit of μA, so that it is safe. Of course, the conductor 31 in the small current cloth 30 is also configured in the same manner as the conductor 21 in the large current cloth 20, so that even if a dry conductor is used, no electrical shock is given to the human body.

Thus, the induced minute current is supplied to the human body, and the bronchus is stimulated and vibrated by the induced minute current to promote sputum. At this time, what is effective as the induced microcurrent supplied to the human body depends on the constitution of the user and the symptoms of asthma. Therefore, depending on the constitution of the user and the symptoms of asthma, LSI
By using the switch S3 and the variable resistor CR2 in 13, the type and the size of the double stimulus amplitude can be appropriately adjusted.

The movable contact S1 of the switch S1
When s is closed on the fixed contact S1a side and the movable contact S2s of the switch S2 is closed on the fixed contact S2b side, a voltage is applied from the AC power supply 12 to one end TR1a on the primary side and the other end TR1b on the high voltage transformer TR1. Is done. The magnitude of the voltage at this time can be adjusted by the variable resistor CR1. After a voltage is applied to the primary side of the high voltage transformer TR1 and converted to the secondary side, the same procedure as in the case where the movable contact S2s is closed to the fixed contact S2a is performed, so that a minute current induced in the human body is obtained. Can be energized.

Further, the movable contact S1s is replaced with a fixed contact S1b.
, A voltage is applied from the AC power supply 12 to one end TR2a and the other end TR2b on the primary side of the thermal transformer TR2. This voltage is transformed to the secondary side by the thermal transformer TR2. Then, a voltage is applied to the heating heater R3, and the large current-carrying cloth 20 can be kept warm. The temperature of the large current cloth 20 at this time can be adjusted to an appropriate temperature by the SCR sensor 16.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, a configuration in which a minute current is simply applied to a human body without providing the LSI 13 or the linear IC 14 may be adopted.

[0032]

As described above, according to the present invention, since the discharge of sputum is facilitated, the discharge of sputum in asthmatic patients can be promoted. Therefore, the use of the drug can be suppressed,
Thus, adverse effects on the human body due to side effects can be reduced. On the other hand, an insulating material is interposed between the conductor and the human body,
Since a low-frequency current caused by the induced electromotive force is applied to the human body, it is possible to prevent an electric shock from being applied to the human body even when a dry-type conductor is used.
