Description

[Detailed description of the invention] [Industrial application field]

The present invention monitors the physiological effects caused by bathing and notifies the bather that a predetermined effect has been obtained.
This invention relates to a bathing effect notification device that increases the efficiency of bathing.

[Conventional technology]

Generally, when bathing in hot water or taking a shower, bathers cannot know the extent to which blood circulation is being promoted, so they end up bathing without achieving the sufficient effect of promoting blood circulation. The effects of promoting metabolism and relieving fatigue may not be sufficient. Additionally, since bathers cannot know their heart rate, bathing for too long can put a greater strain on the heart. A possible solution to this problem is to monitor the degree of blood circulation promotion and heart rate. That is, a bathroom device has been proposed that includes a blood flow rate detection means for detecting the blood flow rate, a heart rate detection means for detecting the heart rate, and a monitor for displaying the blood flow rate and the heart rate (Japanese Patent Application Laid-Open No. 1983-1999). (See Publication No. 54135).

[Problem to be solved by the invention]

According to the above conventional configuration, the bather must judge the physiological effects of bathing based on blood flow and heart rate, which requires physiological knowledge from the bather. There was a problem that it was difficult to use, and even if it was used, the effects of bathing could not be fully brought out. The present invention aims to solve the above problems, and provides a bathing effect notification device that can notify whether or not appropriate physiological effects are being obtained without requiring special knowledge from the bather. This is what I am trying to do.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a blood flow rate detection means for detecting the blood flow rate of a bather, a heart rate detection means for detecting the heart rate of the bather, and a blood flow rate detection means for detecting the bather's blood flow rate and heart rate. The system is equipped with a determination means for determining the bathing effect based on the bathing effect, and a notification means for notifying the bather that a predetermined bathing effect has been obtained.

[Effect]

According to the above configuration, when the determination means determines that an appropriate physiological effect is obtained for the bather based on the blood flow rate and heart rate of the bather, the notification means notifies the bather. Therefore, bathers are not required to have any special knowledge and can easily know that the desired physiological effects have been obtained.

【Example】

In this embodiment, as shown in FIG. 1, a pulse wave sensor 1 serves both as blood flow rate detection means and heart rate detection means. The pulse wave sensor 1 is equipped with a clip-shaped fitting and can be attached to the bather's earlobe or the like. The pulse wave sensor 1 detects increases and decreases in blood flow based on changes in light transmittance, and is attached to an earlobe with a light emitting surface and a light receiving surface facing each other. The output of the pulse wave sensor 1 is in the form of an alternating current component corresponding to a change in blood flow velocity superimposed on a direct current component. The DC component corresponds to the peak value of the blood flow, and when the blood flow is large, the light transmittance decreases and the DC component of the pulse wave decreases. Therefore, the level of the DC component of the pulse wave is an index of blood flow. Furthermore, since the number of pulse waves per unit time is equal to the heart rate, the heart rate can be obtained by counting the number of pulse waves. That is, by detecting the amplitude and period of the pulse wave, it is possible to obtain indicators for blood flow and heart rate. Therefore, the output of the pulse wave sensor 1 is input to the pulse wave DC component detection circuit 2 and the heart rate detection circuit 3, and the pulse wave DC component detection circuit 2 obtains an output value corresponding to the level of the DC component of the pulse wave. At the same time, if the heart rate detection circuit 3 obtains the pulse wave number per unit time as an output value, it is possible to know the tendency of changes in blood flow and heart rate. The output values of the pulse wave DC component detection circuit 2 and the heart rate detection circuit 3 are input to the determination circuit 4 and compared with a predetermined determination value set by the mode selection section 5, and when a predetermined determination result is obtained. ,
The alarm 6 notifies the bather that a predetermined determination result has been obtained. The mode selection section 5 selects the determination circuit 4 according to the wishes of the bather.
For example, you can select the criteria for
Three modes can be selected: if the bather has high blood pressure, if the bather is trying to improve their health, or if they want to relax. Further, the alarm 6 may notify by light or sound, or if the bathtub generates bubbles, it may notify by the generation of bubbles. Incidentally, changes in the DC component of the pulse wave and the heart rate during bathing are as shown in FIG. 2. Figure 2 shows the case of taking a bath at 42°C, which is the average bathing temperature.
The DC component of the pulse wave is shown as a continuous solid line as a reciprocal change (percentage), and the change in heart rate (beats/min) is shown in the soil. The reason why the reciprocal number of the DC component of the pulse wave is shown here is to match the increasing tendency of blood flow. Furthermore, the reciprocal of the DC component of the pulse wave is 100% at rest. As is clear from Figure 2, when bathing begins, the reciprocal of the DC component of the pulse wave (i.e., blood flow) immediately begins to increase, but the heart rate increases after ff14 to 5 minutes have passed since the start of bathing. Begin to. That is, the blood flow in peripheral areas increases immediately after bathing begins, and the heart rate increases 4 to 5 minutes after bathing begins. Based on such physiological effects, determination criteria corresponding to each mode in the mode selection section 5 are set. That is, first of all, if the bather has high blood pressure, it is desirable to increase only peripheral blood flow without putting strain on the heart. Therefore, the heart rate should be increased by 1.2 times the value before bathing. If the reciprocal of the DC component of the pulse wave exceeds 1.1 times,
An alarm 6 is used to inform the bather that he or she may finish bathing. In addition, even if the heart rate exceeds 1.2 times, if the reciprocal of the DC component of the pulse wave is less than 1.1 times the value before bathing, the alarm 6 will notify you that you can extend your bath time a little more. Make it. In other words, when notifying with light, it is sufficient to use continuous lighting to indicate the end of bathing, and intermittent lighting to indicate the extension of bathing.Also, when notifying by sound, it is sufficient to distinguish between continuous sound and intermittent sound. If so, it is sufficient to distinguish between continuous and intermittent occurrence of bubbles. If you want to relax by taking a bath, you can select the relaxation mode using the mode selection section 5. In this case as well, it is desirable to use a bathing method that increases peripheral blood flow without putting strain on the heart. be the same as for high blood pressure. When trying to improve health by taking a bath, if the heart rate exceeds 1.5 times the value before bathing and the reciprocal of the DC component of the pulse wave exceeds 1.2 times, the end of bathing is notified. Do it like this. Further, even if the heart rate exceeds 1.5 times, if the reciprocal of the DC component of the pulse wave is 1.2 times or less, the user is notified that it is better to extend the bathing time. The notification method is the same as for hypertension. In the above embodiment, only the alarm 6 provides notification, but the water temperature may be controlled by the output of the determination circuit 4, and the water temperature may be changed according to the heart rate or blood flow.

【Effect of the invention】

As described above, the present invention includes a blood flow rate detection means for detecting the blood flow rate of a bather, a heart rate detection means for detecting the heart rate of the bather, and a bathing effect based on the blood flow rate and heart rate of the bather. The system is equipped with a determination means for determining whether a bath is effective or not, and a notification means for notifying a bather that a predetermined bathing effect has been obtained. When the determination means determines that a physiological effect appropriate for the person is obtained, the notification means informs the bather, so that the bather is not required to have special knowledge regarding physiological effects, and There is an advantage that the fact that a predetermined physiological effect has been obtained can be easily known by the alarm.
