[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for reducing the addition to the anus by detecting the breathing of a user during defecation.

[0002]

2. Description of the Related Art As a conventional technique relating to the acquisition of biological information during defecation, there is, for example, Japanese Patent Laid-Open No. 5-228116. This is to connect a toilet facility equipped with a urine analysis function, an electrocardiogram recording function, a body fat percentage measurement function, a blood pressure measurement function, and a weight measurement function to a controller via a local area network, and store the biometric information obtained from the toilet facility in the controller. It is stored in a medium and used for health management.

ogical Monitoring Systems Attached to the Bed and
It has been reported to Sanitary Equipments. (Togawa et al.) About a method of measuring an electrocardiogram using a conductive cloth attached to a toilet seat as an electrode.

[0004]

SUMMARY OF THE INVENTION The above-mentioned conventional technique is intended to be useful for health management after storing biometric information collected in the toilet or on the toilet seat. Therefore, there is almost no opportunity for the collected biometric information to be utilized in real time, except for the abnormality detection by the user.

As an example in which the use of biometric information in real time is effective, detection of a breathing state during defecation can be considered. Hemorrhoids are one of the diseases most closely associated with defecation, but one of the causes is excessive breathing. The advice from doctors for patients with hemorrhoids is often "please do not breathe too much." On the other hand, how strong your breathing is when you defecate and how long you can breathe is difficult to understand because you cannot compare it with others.

[0006] When it is difficult to defecate due to constipation or the like, it is effective to stimulate the anus. Some toilet seats for warm water washing have a stimulating function such as massage. The reality is that different people have different standards of goodness. Some people can quickly use the stimulatory function without breathing too much, which can cause a reduction in their ability to defecate themselves. On the contrary, some people do not use the stimulation function easily, and in some cases suffer from hemorrhoids.

However, the conventional configuration has a problem that the collected biometric information cannot be used for detecting breathing. In addition, there is a problem that it is not possible to provide a means for objectively evaluating one's bowel movement. Further, there is a problem in that it is not possible to inform the user of the timing of properly using the anus stimulating function for promoting defecation.

The first purpose is to reduce the potential or pressure at the toilet seat.
Then, at least one of them is measured to detect breathing for defecation, which is useful for health management.

The second purpose is to detect the breath for defecation, which is useful for health care, by measuring the electric potential at the toilet seat .

A third object is to detect body movements which are easily distinguished from noises due to body movements and the like by using a pressure sensor to detect a breath for defecation.

A fourth object is to improve the detection accuracy of breathing for defecation by identifying body movements using a plurality of biological information of electric potential and pressure .

A fifth object is to inform the user of the intensity of breath.

A sixth object is to make an objective evaluation of how to defecate from the rate of breathing time.

A seventh object is to make a more accurate evaluation of how to defecate using both the intensity of breath and the ratio of breath time.

An eighth object is to give a stimulus to a living organ to promote defecation at an appropriate time during defecation.

The present invention has the following effects due to the above-mentioned structure.

In the first solving means, the biometric information detecting means continuously obtains biometric information such as electrocardiogram and body movement of the user during defecation, and the signal processing means is unique to the user when he / she breathes. The generated biometric information is set as a threshold in advance and detected.
Compared with the living body information, it identifies and detects the state of breathing ,
To know.

In the second solution, the amplifying means amplifies the signal from the electrode in direct contact with the skin of the user to a manageable level. Next, the A / D conversion means changes the amplified signal into a digital value, and the feature extraction means extracts the frequency component of the signal waveform by waveform processing such as FFT or the waveform feature itself by pattern recognition or the like.

In the fourth solving means, the amplifying means amplifies a signal from the electrode which is in direct contact with the skin of the user and a signal of a pressure change due to the weight shift of the user from the pressure sensor. Next, the A / D conversion means changes the amplified signal into a digital value, the characteristic extraction means extracts the waveform characteristic of the signal from the electrode, and the signal from the pressure sensor changes per unit time of the pressure sensor. By calculating the amount, the breath of the user is detected from the waveform characteristics when the determination means determines that the body movement is not performed. That is, the pressure sensor detects body movement.

Only when the breath is detected from the electric potential
It is determined to be in the state.

[0033]

Embodiments of the present invention will now be described with reference to the drawings.

(Embodiment 1) FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. The defecation device according to the present embodiment is the biological information detecting means 1
And signal processing means 2. The biometric information detecting means 1 detects biometric information of the user, for example, myoelectric potential near the user's lower abdomen, buttocks, and lower limbs, and pressure distribution of weight on the toilet seat. The signal processing unit 2 recognizes that the user is in a breathing state by identifying a unique biomedical signal generated when the user breathes for defecation from the pattern of the biomedical signal obtained at rest. To do.

As described above, according to this embodiment, the user's breathing state can be detected.

(Embodiment 2) In FIG. 1, the biological information detecting means 1 includes electrodes 3a, 3b,
3c and amplification means 5. Electrodes 3a and 3b
-3c is arranged on the toilet seat 4. Electrodes 3a ・ 3b ・
A silver / silver chloride electrode or the like can be used as the material of 3c. The electrodes 3a and 3c are used as positive and negative electrodes, respectively, and the electrode 3b is used as a body ground. The amplifying means 5 is for amplifying a weak bio-signal of several millivolts, and for example, a bio-amplifier of about 1000 times to 5000 times can be incorporated. In order to obtain a proper output, the amplifying means 5 may be provided with a filter circuit. The signal processing means 2 is composed of an A / D conversion means 6, a feature extraction means 7, and a determination means 8.

When the potential of the buttocks was measured during defecation, a waveform as shown in FIG. 2 was obtained. Fig. 2 (a) shows the waveform at rest, and a clear heartbeat waveform can be confirmed. Figure 2 (b)
Is a waveform at the time of breathing, and it can be confirmed that a slow-wave component with a large amplitude is mixed as an artifact in the waveform at rest. If the mixing of the slow wave component can be confirmed by the signal processing, it can be determined whether the user is resting or breathing.

Therefore, first, the A / D conversion means 6 converts the amplified biomedical signal into a digital value. Next, the feature extraction means 7 performs frequency analysis on the digitized data. When frequency analysis is performed on the resting data shown in FIG. 2A, a peak appears in the power of the frequency (for example, 1 Hz for 60 beats / second) according to the heart rate per unit time. On the other hand, in the breathing waveform of FIG. 2 (b), a power peak should be seen not only at the frequency corresponding to the heart rate but also at the frequency corresponding to the slow wave component. The feature extracting means 7 can be realized by using a microcomputer capable of performing frequency analysis such as FFT, a digital signal processing (DSP) chip, or the like.

The judging means 8 judges whether or not there is a power peak other than the heartbeat cycle based on a preset threshold value. If the peak of the power exceeding the threshold is recognized in the low frequency band corresponding to the slow-wave component, which is an artifact, it can be known that the user is in a breathing state. The threshold used at this time must be set in consideration of noise. A microcomputer or a DSP can be used to realize the determination means 8 as in the feature extraction means 7.

By the way, the structure of this embodiment is characterized in that the user's heartbeat waveform can be obtained when the user is in a resting state. I use the toilet every day, so I
If a recording medium such as a C card is added, it becomes possible to collect heartbeat data over a long period of time. The heartbeat data obtained in this way is extremely useful data for managing the health of the user.

As described above, the present embodiment has an effect of being able to collect the heartbeat data of the user as well as the breath detection by the potential near the buttocks.

(Example 3) FIG. 3 shows the configuration of the third embodiment of the present invention.

In FIG. 3, pressure sensors 9a, 9b, 9
c and 9d are respectively arranged in the toilet seat 4 and constitute the biological information detecting means 1. The signal processing means 2 is composed of an A / D conversion means 6, a feature extraction means 7, and a determination means 8.

The arrangement of the pressure sensors 9a, 9b, 9c and 9d is designed so that the weight shift of the user on the toilet seat can be detected. That is, the movement of the weight before and after the pressure sensor 9a
The pair of 9c and the pair of pressure sensors 9b and 9d can be detected, and the left and right weight movements can be detected by the pair of pressure sensors 9a and 9b and the pair of pressure sensors 9c and 9d, respectively. The outputs of the pressure sensors 9a, 9b, 9c, 9d are stored in the first storage means 10. Pressure sensors 9a, 9b, 9c, 9
In addition to strain gauges, polyvinylidene fluoride (PVD)
Piezoelectric elements such as F) can be used.

Although most of the cause of the weight shift of the user on the toilet seat 4 is due to sitting down again, a slight weight shift is recognized even when he / she breathes. This is because the movement of body weight is much slower than that in the case of reseating normally, and the tremors on the body surface that accompany breathing can be captured. This tremor has a lower amplitude and higher frequency than normal weight movement, and its detection can be easily realized by frequency analysis.

As described above, according to the present embodiment, it is possible to correctly detect a biomedical signal generated with a breath that is difficult to distinguish from body movement.

(Example 4) FIG. 4 shows the configuration of the fourth embodiment of the present invention.

In FIG. 4, the toilet seat 4 has electrodes 3a, 3
b, 3c and pressure sensors 9a, 9b, 9c, 9d are provided. Electrodes 3a, 3b, 3c and pressure sensor 9
The outputs of a, 9b, 9c and 9d are connected to the amplification means 5. The signal processing means 2 is composed of an A / D conversion means 6, a feature extraction means 7, and a determination means 8.

The electrodes 3a, 3b, 3c measure the potential near the user's buttocks. The potential near the buttocks has the characteristic that the signal peculiar to the user's breath is clearly reflected in the waveform, but there is also the problem that it allows the mixing of artifacts other than breath such as body movement. Also pressure sensor 9
a, 9b, 9c and 9d measure the weight shift of the user and the pressure change on the body surface. The pressure information on the section 4 is
While there is a feature that the user's body movement can be accurately detected, there is a problem that it may be difficult to distinguish between resting data and breathing data due to individual differences in breathing. When detecting breathing, it is very important to distinguish whether the artifact mixed in the biological signal is due to body movement or breathing. In this embodiment, the electrodes 3a, 3
The mixture of artifacts due to b and 3c is examined, and the presence or absence of weight movement due to body movement is examined with pressure sensors 9a, 9b, 9c and 9d. If the direction of body weight movement is not a problem, the cost can be reduced by providing the pressure sensor only in one place.

In the signal processing means 2, the feature extracting means 7
Performs frequency analysis on the potential near the buttocks using the electrodes 3a, 3b, 3c and extracts the component of the artifact mixed in the signal. On the other hand, the pressure sensors 9a, 9b, 9c, 9
Regarding the signal from d, the temporal difference between the signal values of the respective pressure sensors is calculated, and when the amount of change per unit time exceeds a predetermined threshold value, it is interpreted that body movement has occurred. The determination means 8 determines that the user is in a breathing state when the artifact near the buttocks is mixed with the artifact and the body movement is not detected.

As described above, according to this embodiment, since the characteristics of the two kinds of biometric information are used for the detection of the breath, it is possible to detect the breath more accurately.

(Embodiment 5) FIG. 5 is a block diagram showing the configuration of a fifth embodiment of the present invention. The feature extraction means 5 has a frequency analysis means 10, and the determination means 8 has an intensity estimation means 11. Further, the output of the intensity estimating means 11 is connected to the notifying means 12.

It is widely known that hemorrhoidal disease has a strong correlation with excessive breathing, and the advice of a specialist to a patient is very much about keeping breathless. However, patients cannot know exactly how strong their breath is because they cannot compare with others.

Therefore, in this embodiment, the frequency analysis means 10 determines the power spectrum of the output of the A / D conversion means 5. If there is a mixture of heartbeat waveforms, power peaks appear at integral multiple frequencies with the fundamental frequency as the starting point. Furthermore, when low-frequency artifacts due to breathing are mixed, a power peak is also seen at the corresponding frequency.

The intensity estimating means 11 is the frequency analyzing means 10.
The peaks due to the artifacts of the low frequency components are identified in the power spectrum output by. Heart rate is usually 0.8 ~
Since it is 1.5 Hz, the peak of the power seen in the lower frequency band is assumed to be the fundamental frequency of the artifact.
Usually, the amplitude of the artifact tends to increase if the causative biological activity is active. Therefore, the power value corresponding to the frequency of the artifact can be used as an index of the intensity of breath. This peak value is 5
The user is informed of the level value through the notifying means 12 by classifying it into levels.

As described above, according to the present embodiment, the deterioration of symptoms is prevented by notifying a patient suffering from hemorrhoidal disease and the like of the strength of objective breathing, and also for general users. It is effective in preventing hemorrhoids.

(Sixth Embodiment) FIG. 6 is a block diagram showing the configuration of a sixth embodiment of the present invention.

In FIG. 6, the seating detecting means 13 is the toilet seat 4
And is connected to the first timing means 14 and the second timing means 15. Also, the determination means 8 is the second
Is connected to the storage means 15. Further, the outputs of the first storage means 14 and the second storage means 15 are the evaluation means 16
Connected to be sent to.

When the user sits on the toilet seat 4, the seating detection means 13 changes the output signal from 0 to 1 as a seating signal. When the user stands up from the toilet seat 4, the output signal is set to 0. The seating detection means 13 can be easily realized by using a pressure sensitive switch or the like. The first timing means 14 is the seating detection means 13
When the output signal value 1 of 1 is received, the clocking is started with 0 as an initial value, and the clocking is stopped at the output signal value 0.

The signal processing means 2 outputs 1 to the second timing means 15 as an output signal only while the user is breathing.
Is output, and 0 is output otherwise. Second timing means 1
In step 5, while the signal value from the seating detection means 13 is 1, the time when the breathing signal from the signal processing means 2 is 1 is counted while adding. Further, when 0 is received as a signal value from the seating detection means 13, the counter is reset to 0.

The evaluation means 16 obtains the ratio of the breathing time to the total defecation time from the outputs of the first timing means 14 and the second timing means 15, and evaluates defecation with the ratio thereof. The ratio is obtained by dividing the (output value of the second timing means) by the (output value of the first timing means). Generally, except for diarrhea, excretion of stool with less breath is less burdensome to the anus, and it can be considered that it is desirable for patients with hemorrhoidal disease. The smaller the number, the better the defecation is evaluated. The evaluation has five levels, and the notification means 12 visually notifies the user.

As described above, according to this embodiment, it is possible to provide an objective index of defecation that is desirable for patients with hemorrhoidal disease.

(Embodiment 7) In FIG. 6, the storage means 17 is arranged so as to be located between the signal processing means 2 and the evaluation means 16. The signal processing means 2 outputs breath intensity information to the storage means 17 each time a breath occurs. The storage means 17 stores the intensity information as needed. The evaluation means, when evaluating defecation,
The breath intensity information stored in the storage unit 17 is also used. At the time of defecation, if the number of breaths is small, but the breaths are excessively strong, it may not be the preferred way of defecation. On the contrary, even if the breathing time becomes longer due to constipation, if the strength of each breathing stays at an appropriate level, it may not be said that the bowel movement is bad.

In order to reflect such an idea in the evaluation, for example, a method of expressing the breathing intensity and the breathing time with level values of about 10 levels each and multiplying them to obtain the evaluation value is available. is there. For example, even if the level value of the breath intensity is a value of 8 indicating that the user has breathed fairly strongly, the evaluation value is 24 if the value of 3 indicates that the breathing time is relatively short. In addition, if the strength and the time are both above the average value of 6, the evaluation value is 36. in this case,
The smaller the evaluation value, the lesser the burden on the body, particularly the anus, and the lesser the bowel movement is.

The method of defecation varies from person to person, and some people also use it as a time for relaxing such as reading. Some people leave. The problem is that users cannot objectively evaluate their bowel movements. It is said that people who breathe too much are more likely to suffer from hemorrhoids, but what does that mean? Here, it is meaningful to use two indicators, the intensity of breath and the ratio of time of breath. Regarding the breathing time, the absolute amount of the breathing time may be used as an evaluation index instead of the ratio to the defecation time.

As described above, according to the present embodiment, there is an effect that more accurate and objective evaluation of defecation can be performed by using the two indices of breath intensity and breath time.

(Embodiment 8) FIG. 7 is a block diagram showing the structure of an eighth embodiment of the present invention.

In FIG. 7, the control means 18 is constructed so that the respective outputs of the signal processing means 2, the first timing means 14 and the second timing means 15 are input. The stimulating means 19 is arranged under the toilet seat and is connected to the control means 18.

The time from sitting to finishing bowel movements is
Even the same user will differ greatly depending on daily health conditions such as constipation and diarrhea. Everyone will have the experience of not being able to defecate despite sitting for a considerable amount of time and breathing many times, especially during constipation.
As a coping method in such a case, it is known that proper stimulation to the anus is effective. In the present embodiment, the user automatically recognizes that the bowel movement is difficult for some reason and stimulates the anus.

The first time measuring means 14 measures the sitting time of the user. Further, the second time measuring means 15 measures the time when the user breathes while sitting. In the control means 18, the memory 20 stores a first threshold value for judging that the sitting time of the user is a certain time or more. The memory 21 also stores a second threshold value for determining that the breathing time has reached a certain level or more. The comparator 22 includes the contents of the first timing means 14 and the first contents stored in the memory 20.
And the output signal level is made high if the value of the first clocking means 14 is larger than the first threshold value. Similarly, the comparator 23 includes the second timing means 15
Is compared with the second threshold value stored in the memory 21, and if the value of the second timing means 15 is larger than the second threshold value, the output signal level is made high. The AND gate 24 raises the output level to drive the stimulating means 19 only when the outputs of the comparators 23 and 24 are both high. This means that the user has been breathing for a period of time that exceeds the first threshold value and has exceeded the second threshold value since the user sat down. The stimulation unit 19 receives a signal from the control unit 18 and stimulates the anus of the user. The stimulating means 19 can be realized by using a washing nozzle of a warm water washing toilet seat or the like. Note that, in consideration of hard stool due to constipation, a solution of lubricant may be sprayed from the nozzle in addition to normal running water. Instead of automatically stimulating the anus, it may be displayed that the anus should be stimulated via the notification means, and the actual stimulation may be left to the user's judgment.

As described above, according to this embodiment, there is an effect that the anus can be automatically stimulated to promote defecation even when the user is having difficulty.
