Embodiments will be described below with reference to the drawings.

FIG. 1 shows the appearance of a respiratory tractor exerciser according to the present invention. The configuration of the electric circuit inside the main body 20 is shown in the block diagram of FIG.

The breath blowing means 10 has a blow port 11 for blowing breath at one end and a discharge port 13 at the other end.
, And a vent opening 14 is opened in the middle. The outlet 13 has a large-diameter opening area so as to obtain a small airflow resistance when used in a measurement mode described later. The adjusting body 12 has a cap shape that covers the outside of the outlet 13, and has a small-diameter outlet 13 ′ at one end for obtaining a large airflow resistance in a training mode described later (FIG. 2). The airflow resistance adjusting means is constituted by the adjusting body 12 and the outlet 13. That is, a large airflow resistance is obtained by fitting the adjustment body 12 to the expiration blowing means 10, and a small airflow resistance is obtained by removing the adjustment body 12.

One end of a ventilation pipe 15 is connected to the ventilation port 14, and the other end is connected to a connecting member 16 with the main body 20.
Connected to The ventilation pipe 15 may be made of a bellows-like or elastic material that can be bent and expanded and contracted. The ventilation pipe 15 constitutes a part of the ventilation path 21 to the common pressure detecting means 31. The connection member 16 is connected to the main body connection port 22.
It is desirable that it can be attached to and detached from. The common pressure detecting means 31 is, for example, a diffusion type semiconductor pressure sensor. The output signal of the common pressure detecting means 31 is a signal having a path 32 having different gains and an A / A for converting an analog value to a digital value.
The signal is input to the arithmetic unit 30 via the D converter 33. The calculating means 30 is composed of a central processing unit (CPU), and controls the entire control.

The switching means 23 selects a training mode and a measurement mode, and also serves as a frequency setting means in the training mode. When the user moves to each position of 50, 100, or 150, the training mode is selected, the number becomes the set value of the number-of-times setting means, and the designated value is displayed on the display unit 36 which is one of the notifying means. Here, expiration blowing means 1
When the airflow resistance of 0 is adjusted to a larger value and the expiration is blown into the blow-in port 11, the pressure of the expiration is applied to the common pressure detecting means 31 via the ventilation path 21 and detected as a voltage value. The detected signal is voltage-amplified by a path having the smallest gain among paths 32 having different gains, converted into a digital signal through an A / D converter 33, and input to the arithmetic means 30. The calculating means 30 calculates the expiratory pressure from the obtained digital signal.

Reference numeral 24 denotes a pressure intensity setting means. In the training mode, the user can set a pressure value according to the degree of growth or function of his or her respiratory organ and start training.

Here, the pressure level lamp 26 is associated with the pressure intensity setting means 24. When the pressure intensity setting means 24 is set to 1, even a small exhalation pressure is lit up to 8, and when set to 5, a large exhalation pressure is set. Unless added, it does not light up to 8. This is shown in FIG.

When the pressure level lamp 8 turns on,
The value of the display unit 36 decreases by one. When the signal becomes 0, the music signal output from the melody IC 29 is current-amplified by the amplifier 63, and the melody sounds through the speaker 28 which is one of the notifying means. Here memory switch 2

When the airflow resistance of the airflow is adjusted to a smaller value and the expiration is blown into the air inlet 11, the pressure of the expiration generated according to the airflow rate is increased in the ventilation path 2.
The voltage is applied to the common pressure detecting means 31 via 1 and is detected as a voltage value. The detected signal is voltage-amplified by an optimal path from among paths 32 having different gains, converted into a digital signal through an A / D converter 33, and input to the arithmetic means 30. The calculating means 30 calculates an air flow rate from the obtained digital signal, and calculates a peak flow, which is the maximum value thereof, and a value obtained by integrating the air flow rate for one second, that is, a one-second amount, which is a maximum expiration amount that can be continuously output for one second. Is calculated. Display 3

FIG. 10 shows a method of transmitting training data and measurement data to the outside. FIG. 3A shows that the patient directly receives the main body 2.
0 is brought into a hospital, and the main unit 20 and a computer in the hospital are connected via an RS-422 or RS-232C interface. In this case, the computer software starts up, and according to the processing procedure,
When the transmission switch 62 is pressed, the arithmetic unit 30 transmits the training data and the measurement data stored in the internal storage unit 39 to the computer via the external communication unit 40.

In the method shown in FIG. 2B, the computer and the main body 20 arranged on the patient side (home) are connected to the RS-422 or R-422.
This is a method of connecting via a S-232C interface, connecting a computer and a modem via an RS-422 or RS-232C interface, and transmitting training data and measurement data over the same telephone line. In this case, similarly to FIG. 10A, the software of the patient's computer is activated, and the transmission switch 6 is turned on in accordance with the processing procedure.
When the user presses 2, the arithmetic unit 30 receives the training data and the measurement data stored in the internal storage unit 39 through the external communication unit 40 into the patient's computer, and transmits the data to the hospital computer through the telephone line.

In the latter case, the training data and the measurement data are remotely grasped, and instructions can be received by telephone or the like, so that the burden of going to the hospital can be reduced.

Since the apparatus of the present invention is configured as described above, when the apparatus is used as a respiratory exerciser, first, the switching means 23 is moved to any one of the positions 50, 100, and 150, and the training mode is selected. Keep it. Next, the airflow resistance is adjusted in a direction to increase the airflow resistance, and expiration is blown into the expiration blowing means 10. Subsequent usage and operation are as follows.
It is almost the same as that of No. 65.

That is, in the training mode, at the beginning of the training, the pressure intensity setting means 24 is set to the position 1 and the switching means 23 is set.
Is set to a minimum of 50. At this time, a numeral 50 is displayed on the display unit 36. Therefore, breath 11
When the intensity of the exhalation pressure reaches the set value of the pressure intensity setting means 24 for setting the intensity of the exhalation pressure, all of the pressure level lamps 1 to 8 are lit and displayed. Decrease the number by one. In other words, if the displayed number does not decrease even after the insufflation, the user knows that the insufficiency in insufflation is insufficient and the user must insufflate more strongly. Also at this time, the level lamp 26 is turned on, so that it is possible to know how much effort should be made, so that the user can train while feeling the strength of the exhalation.

When the storage switch 25 is pressed, the training data (the set value of the number of times set by the switching means 23, the set value of the intensity setting means 24, the number of times that the level lamp 26 is turned on, and the year and month at that time) , Day, hour and minute clock information) are stored in the internal storage means 39 and the external storage means 34. Further, when the print switch 61 is pressed, the internal storage means 3
The training data stored in 9 is printed out to the printing means 41, and the daily training situation can be recorded.

On the other hand, when this is used for measuring lung function, first, the switching means 23 is moved to either the PEF or FEV ₁ position to select a measurement mode.
Next, the airflow resistance is adjusted to a smaller value. Breath blowing means 10
When the breath is inhaled, both the peak flow and the amount of one second are calculated. When the storage switch 29 is pressed, the measured data (the calculated peak flow and the amount of one second and the year, month, day, and hour at that time) are calculated. , Minute clock information) in the internal storage means 39
Is stored in the external storage means 34. Further, when the print switch 61 is pressed, the measurement data stored in the internal storage unit 39 is printed out to the printing unit 41, and the daily change in lung function can be recorded.

By combining the printed training data and the measured data, it is possible to objectively and quantitatively know the daily respiratory training and how it led to the improvement of lung function. It can be expected to have a great effect on treatment and continued training of patients.

When the transmission switch 63 is pressed, the training data and the measurement data stored in the internal storage means 39 are transmitted to the RS-42.
2 or RS-232C, and can be submitted directly to the doctor through the external communication means 40 for diagnosis. As described above, since the medical condition data of a specific patient is remotely grasped, the burden of going to the hospital is reduced, and an instruction can be received by telephone, for example. In addition, as a transmission method, other than a modem, ISDN (Integrated Service) is used.
ces Digital Network) interface may be used.

FIG. 3 shows another example of the airflow resistance adjusting means.
The small diameter outlets 51 and 53 are respectively opened at the centers of the end faces of the exhalation blowing means 10 and the adjusting body 12, and two large diameter outlets 50 and 52 are respectively opened symmetrically with the outlets 51 and 53. The reason why the large-diameter outlet is arranged symmetrically with respect to the small-diameter outlet is as follows.
This is to prevent the airflow from being biased. If the adjusting body 12 is rotated so that only the small-diameter outlets 51 and 53 are opened, the airflow resistance is increased. If all the outlets 51, 53, 50 and 52 are opened, the airflow resistance is reduced. Becomes

Further, the entire expiration air blowing means 10 having different areas of the outlet 13 may be replaced to adjust the air flow resistance. In the example of FIG. 7, a large airflow resistance for the training mode and a small airflow resistance for the measurement mode are separately prepared as the expiration blowing means 10. Here, the connection member 1 with the main body 20
6 are different shapes a and b, and the shape information is
By inputting 0, it is possible to automatically determine the training mode and the measurement mode. In addition, as a method of generating airflow resistance, the outlet of the expiratory air blowing means 10 may be closed with a thin tube bundle or a wire mesh.

A method for calculating the expiratory pressure in the training mode, and a method for calculating the peak flow and the amount per second in the measurement mode will be described below.

Method 1 (see FIG. 4) The common pressure detecting means 31 is driven by a constant current,
The potential difference Δv proportional to p (unit: Pa) is output. Δ
v = αΔp (α: constant). The output of the common pressure detecting means is amplified by a differential amplifier (gain Gs) and the A / D converter 3
Enter 3 In addition, the output of the differential amplifier is
(Gain G ₁ ), amplifier 2 (G ₂ ), and amplifier 3 (G ₃ ), and input to the A / D converter. Gains G ₁ , G ₂ , G ₃
Is selected so that 1 <G ₁ <G ₂ <G ₃ and a signal Δv having a wide dynamic range can be accurately obtained by an A / D converter having a limited resolution.

The input voltage at this time, A / D _{converter, V 1 = GsΔv = αGsΔp ...} V 2 = G 1 GsΔv = αG 1 GsΔp ... V 3 = G 2 GsΔv = αG 2 GsΔp ... V 4 = G 3 GsΔv = αG ₃ GsΔp. Here, V ₁ <V ₂ <V ₃ <V ₄ . (Unit: V).

The CPU A / D converts V ₁ in the training mode.
A / D conversion is performed for V ₂ , V ₃ , and V ₄ in the measurement mode. Therefore, the output of the common pressure detecting means 33 and A /
The gain between the input to the D-converter is G
Three different paths, ₁ Gs, G ₂ Gs and G ₃ Gs, are used, all of which are higher than the gain Gs in the measurement mode.

In the embodiment, three amplifiers (amplifier 1, amplifier 2, and amplifier 3) are used. However, if the resolution of the A / D converter is low, the number of amplifiers is increased in order to obtain a high-precision operation result. Should be increased. Conversely, if the resolution of the A / D converter is high, the number of amplifiers may be reduced.

<Method of calculating expiratory pressure in training mode> The switching means 23 is moved to any one of the positions 50, 100 or 150 to select the training mode. Breath blowing means 10
Is adjusted by airflow resistance adjusting means so that a large airflow resistance is obtained when expiration is blown, or expiration blowing means 10 having a large airflow resistance is used. The expiratory pressure is obtained as follows. Is voltages V ₁ generated in response to the strength of the breath pressure when blows from expiratory air sucking means. C
PU can know the voltage V ₁ by the value of the A / D converter. The expiration pressure Δp is calculated from the formula as Δp = V ₁ / (αGs).

<Method of Calculating Peak Flow and One Second Amount in Measurement Mode> The switching means 23 is moved to any position of PEF or FEV ₁ to select the measurement mode. CPU
Calculates both the peak flow and the 1 second amount. The expiratory air blowing means 10 adjusts the airflow resistance in a small direction, or uses one having a small airflow resistance. When the breath is blown into the expiration blowing means 10, a pressure Δp (unit: Pa) that satisfies Δp = β (Δf) ² (β is obtained by an experiment) according to the blown air flow rate Δf (unit: liter / minute). Occur.
The A / D input voltages V ₂ , V ₃ , V _{4 at} this time are:
It is shown by the formula. Therefore, V ₂ , V ₃ depending on the value of A / D
, If the voltage of V ₄ is obtained, air flow rate Delta] f _{is, Δf = √ {V 2 /} (αβG 1 Gs)} ... Δf = √ {V 3 / (αβG 2 Gs)} ... Δf = √ {V 4 / (ΑβG ₃ Gs)｝. Here, in order to calculate the air flow rate with high accuracy, it is necessary to select a voltage value within V ₂ , V ₃ , and V ₄ that falls within a voltage range where A / D exchange can be performed correctly and is as large as possible. .

The method of calculating the peak flow and the amount per second will be described with reference to the flowchart of FIG. From the expiration inhalation means, inhale in a short time to the maximum. The CPU uses V ₂ , V ₃ ,
V ₄ in sequence at a sufficiently short interval (eg, 1 mS)
D conversion is continuing. The value of the A / D converter at that _{time, V 2: D 21, D} 22, D 23, D 24, ...... ( maximum value _{D 2 h) V 3: D} 31, D 32, D 33, D 34, ...... (maximum value _{D 3 i) V 4: D} 41, D 42, D 43, D 44, and ... (maximum value D ₄ j). Here, D ₂₁ , D ₃₁ , and D ₄₁ are the values of the A / D conversion of V ₂ , V ₃ , and V ₄ at the moment when the breath is blown, respectively.

When the maximum value D ₄ j is not saturated, that is, when V ₄ is in the voltage range where A / D conversion can be performed correctly, the maximum value of V ₄ is obtained from D ₄ j.
The air flow rate Δf can be calculated from the equation. This value is the peak flow. The one second amount can be obtained by integrating the air flow rate Δf (time series) obtained from D ₄₁ , D ₄₂ , D ₄₃ ,... For one second. When D ₄ j is saturated, that is, V ₄
Is outside the voltage range where A / D conversion can be performed correctly,
The process proceeds down the flowchart shown in FIG.

Similarly, when the maximum value D ₃ i is not saturated, the air flow Δf is calculated by the equation from the maximum value of V ₃ , and this value is the peak flow. The amount of one second is D ₃₁ , D
₃₂ , D ₃₃ ,..., Can be obtained by integrating the air flow Δf (time series) obtained for one second.

When D ₃ i is saturated, proceed downward and calculate the peak flow with the maximum value D ₂ h. D ₂ h is the gain G of the differential amplifier so that it does not easily saturate even when used by a healthy person.
and determines the gain G ₁ of s and amplifier. Since the maximum value of V ₂ is obtained from D ₂ h, the air flow Δf is calculated by the equation. This value is the peak flow. The amount of one second is D ₂₁ , D
_22, D _23, can be obtained by integrating ... 1 sec airflow Delta] f (time series) with more determined.

Method 2 (see FIG. 6) If the power supply voltage of the differential amplifier can be set high, and therefore the output amplitude of the differential amplifier can be large, the gain Gs of the differential amplifier is set high, and the amplifier 1 and the amplifier 2 are set. , Amplifier 3
Instead, attenuator 1, attenuator 2, and attenuator 3 may be used. Attenuator 1 (gain H ₁ ), attenuator 2 (gain H
₂ ), the gain of the attenuator 3 (gain H ₃ ) is H ₁ <H ₂ <H ₃
<1, a signal ΔV having a wide dynamic range (unit:
V) is selected so that the A / D converter having a limited resolution can accurately obtain V). Common pressure detecting means 31
Outputs a potential difference Δv proportional to the expiration pressure Δp (unit Pa). Δv = αΔp (α: constant).

At this time, the input voltage of the A / D converter is V ₁ = H ₁ GsΔv = αH ₁ GsΔp V ₂ = H ₂ GsΔv = αH ₂ GsΔp V ₃ = H ₃ GsΔv = αH ₃ GsΔp V ₄ = GsΔv = αGsΔp Becomes Here, V ₁ <V ₂ <V ₃ <V ₄ . The CPU V ₁ A / D conversion when the training mode, the V _2, V _3, V ₄ A / D conversion when the measurement mode.

Although three attenuators (attenuator 1, attenuator 2, and attenuator 3) are used, if the resolution of the A / D converter is low, the attenuator is used in order to obtain a highly accurate calculation result. The number of vessels should be increased. Conversely, if the resolution of the A / D converter is high, the number of attenuators may be reduced. The following calculation method is the same as the method 1.
