[0013]
A measuring section 6 for measuring the weight and pulse wave of the bather is configured on the half body bathing surface 1b.
The measuring unit 6 is provided with a weight measuring meter 61. The weight measuring meter 61 includes a sitting portion 61a on which a bather who is a person to be measured sits, and a sensor portion 61b for detecting body weight. . The sensor part 61b is comprised by load cells, such as an electrostatic capacitance type, an electrical resistance wire type, and a strain gauge type, for example.

[0017]
A method for calculating the body fat percentage and the degree of arteriosclerosis in the health care bathing apparatus configured as described above will be described.
As shown in FIG. 4, when the bather sits on the seat 61a on the half body bathing surface 1b, takes a bath in the bathtub 1 in a half body bathing state (S101), and presses the measurement button 3a of the remote controller 3 to turn it on (S102). ), The water level change of the bathtub water 10 that has risen due to bathing is detected by the water level sensor 22 and input to the control unit 31 that is a calculation means (S103).
[0018]
The body weight of the bather is measured by the body weight meter 61 and input to the control unit 31 (S104). Based on this, the body weight in the air is calculated (S105), and the body fat percentage (S106). Is calculated.
[0019]
W = Ww + ρΔV (1 ′)
Specifically, in this example, the body fat percentage is calculated using the underwater body weight method. First, the water volume ΔV calculated from the water level change detected by the water level sensor 22 and the measured underwater Using weight Ww, weight W in air is calculated in consideration of buoyancy ρΔV in water.
ρ = density of water Next, assuming that the body weight in the air is W and the bather's volume is V, the body specific gravity D of the bather is obtained by the following equation (1).
D = α × W / V (1)
[0020]
The bather's volume V is obtained from the amount of water corresponding to the water level rise from the water level before bathing detected by the water level sensor 22 to the water level during bathing.
In this case, since the ratio of the volume of the lower part from the upper waist part that has entered the water and the volume of the upper part from the upper waist part that has not entered the water is substantially constant, this ratio corresponds to the rise in the water level. The volume of the whole body is obtained from the amount of water.
Further, α in the equation (1) is a coefficient of the water level measurement condition in consideration of the correction of the residual air amount generated by the operation such as breathing during underwater measurement.
And body fat percentage is calculated | required by substituting the body specific gravity D calculated | required by Formula (1) to well-known following Formula (2).
Body fat percentage (%) = {(4.570 / D) −4.412} × 100 (2)
The calculated body fat percentage is displayed on the display unit 32 of the remote controller 3 serving as a notification unit, and / or sound output from the sound output unit 33 and notified. In this case, the weight in the air calculated from the weight in water measured by the weight meter 61 can also be notified.
[0022]
Simultaneously with the calculation of the body fat percentage, the degree of arteriosclerosis of the bather is determined.
When the bather presses the measurement button 3a to turn it on, the pulse wave of the bather is detected by the pulse wave sensor 65 and input to the control unit 31 (S113). The pulse wave detected by the pulse wave sensor 65 is a volume pulse wave as shown in FIG. 5A, and this volume pulse wave is accelerated by the control unit 31 as shown in FIG. 5B. Is converted to
[0023]
Here, the pulse wave refers to a waveform pattern of a change in volume caused by a change in pressure in a blood vessel or expansion and contraction of a blood vessel wall, which occurs with the heartbeat. The volume pulse wave indicating the change in blood volume (blood vessel volume) reacts sensitively to the health level, the degree of arteriosclerosis, etc., and can detect these states appropriately. The pulse wave is measured.
[0024]
That is, when blood is pumped from the heart, the pressure in the artery increases and the blood vessels swell, and when the blood flow returns from the veins to the heart, the pressure decreases and the blood vessels contract. For example, when a blood vessel is soft, the extent to which the blood vessel swells increases. Conversely, when the blood vessel is hard, the extent to which it swells decreases.
Such a change in the state of the blood vessel is clearly reflected in the volume pulse wave, but in the volume pulse wave detected from the bather's buttocks, the undulation at the inflection point of the waveform is small. It is difficult to interpret the dynamics of blood circulation.
Therefore, the detected volume pulse wave is differentiated twice with respect to time and expressed as an acceleration pulse wave, thereby emphasizing the inflection point of the waveform so that the dynamics of peripheral blood circulation can be grasped more easily.
[0025]
The acceleration pulse wave converted from the volume pulse wave is subjected to waveform analysis by the control unit 31 (S115).
For example, the acceleration pulse wave can determine the state of peripheral blood circulation by analyzing the states of four inflection points of points a, b, c, and d shown in FIG.
For example, in the pulse waveform shown in FIG. 6, the drop at the point b is larger than the wave height at the point a, the point c is located above the base line BL, the drop at the point d is small, and the blood circulation is good. This indicates that the degree of arteriosclerosis is low.
On the other hand, as shown in the pulse waveform shown in FIG. 7, when the drop at the point b is small, the point c is lowered to the same position as the point b, and the drop at the point d is larger than the drop at the point b. This indicates that blood circulation is poor and arteriosclerosis is in progress.
[0026]
Thus, by analyzing the shape of the acceleration pulse wave, the degree of arteriosclerosis is determined, for example, in a plurality of stages (S116), and the result is displayed on the display unit 32 of the remote controller 3 as a notification unit. Displayed or / and acoustically output from the acoustic output unit 33 and notified.
The obtained acceleration pulse wave can also be displayed on the display unit 32 as it is.
[0027]
As described above, health problems caused by obesity without bathing the tub 1 in a half-bath state and entering complicated data such as the weight, sex, and age of the bather in advance. It is possible to easily and simply grasp the body fat percentage and the degree of arteriosclerosis due to excessive cholesterol, etc., and it can be used as useful health prevention information.
[0028]
In addition, the degree of arteriosclerosis notified by the display unit 32 and / or the acoustic output unit 33 is determined based on the acceleration pulse wave obtained by converting the measured volume pulse wave, and thus determination is easy. Accurate and useful health management data can be obtained.
[0029]
Furthermore, since the pulse wave sensor 65 for detecting the bather's pulse wave is disposed on the half-body bathing seat surface 1b of the bathtub 1, the pulse wave can be stably brought into contact with the bather's buttocks with an appropriate pressure. It is possible to accurately measure the degree of arteriosclerosis.
The weight meter 61 is also disposed on the half-body bathing surface 1b, and measures the weight of the bather in a half-bath state with relatively little buoyancy, so that accurate weight can be stably measured. Is possible.
[0030]
In addition, it is said that the body warms moderately by bathing, blood circulation improves and can be relaxed and is good for health, but if the body warms up too much, it may cause hot flashes or heat stroke, It is important to know the appropriate bathing time and manage your health.
Therefore, in this health care bathing apparatus, the temperature sensor 66 provided in the seating portion 61a of the weight measuring meter 61 measures the temperature of the bather's buttocks, and the controller 31 measures the rise in the body temperature of the bather since bathing. The bathing time is determined by determining the warming condition of the body by bathing, and bathing information appropriate for each bather is notified.
[0031]
As shown in FIG. 8, when the bather takes a bath and sits on the seat 61a of the weight meter 61 (S201), the temperature sensor 66 embedded in the seat 61a starts measuring the body temperature of the bather. (S202). As shown in FIG. 9, the bather's body temperature rises due to bathing, but the body temperature is continuously measured during bathing, and the body temperature rise from the start of bathing is calculated by the control unit 31 (S203). ).
Then, it is determined whether or not the body temperature increase from the time of bathing has reached a predetermined increase value ΔT (S204), and when the body temperature increases by the predetermined increase value ΔT, it is determined that the body of the bather has been warmed. Then, bathing information is notified (S205).
The bathing information is, for example, notified by the display unit 32 and / or the sound output unit 33 of the time of bathing or the content of prompting bathing.
[0032]
In this way, the body temperature of each bather is directly measured, the degree of warming of the body is judged from the degree of the rise in body temperature, and bathing information such as prompting bathing is notified, so appropriate The bathing time can be grasped, and it can be used for health management to prevent the bather's body from warming up and getting hot and heat stroke.
[0033]
