Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a simple portable blood pressure monitor built into a wristwatch.

In recent years, with the increasing complexity and diversification of social life and the diversification of dietary habits, the rate of death from diseases of the circulatory system, that is, the heart and blood pressure system, has been increasing.

This is due to the increase in stress due to the diversification of social life and eating habits, lack of exercise, and excessive intake of calories in dogs, but also as treatments for other diseases progress and the population ages. It depends on who you are.

This is why deaths from heart disease, cerebral hemorrhage, etc. have been increasing in recent years.

Therefore, it is important to be careful about the above-mentioned diseases in daily life, but constant monitoring of blood pressure is an effective precaution.

However, at present, it is not common for the general public to constantly measure their blood pressure in their daily lives, and they only occasionally measure their blood pressure during health checkups at hospitals or workplaces.

One of the reasons for this is that current blood pressure monitors are large and expensive, and many of them cannot be measured by humans or are not portable.

In view of these points, it is an object of the present invention to provide a sphygmomanometer that is simple, convenient to carry, and can be measured by one person, that is, a wristwatch-type sphygmomanometer that allows measurements to be taken at any time and at any time.

Normally, 4m pressure is measured at the upper arm, but since the blood pressure monitor of the present invention is also used as a wristwatch, it is measured at the lower arm near where the wristwatch is worn, which is different from the usual measurement position. Since the values are different, it is necessary to take measures to correct the differences in measured values in advance.

FIG. 1 is a simplified diagram of a developed view of a wrist watch equipped with a suppressor according to the present invention.

1 is liquid crystal, light emitting diode, Ellen 1 ~ Lochromism,
The digital display panel 2 is an exterior top cover, and an ultra-small speaker 8 is mounted thereon.

3 and 3' are a clock circuit, a frequency dividing circuit, a counter, a decoder, etc., as well as an AI') converter for blood pressure measurement,
It has a built-in integrated circuit such as a counter and a MOS.

Reference numeral 5 denotes a crystal oscillator 4 for obtaining a clock reference frequency, and an external operating device.

Reference numeral 6 is a transducer 1 to transducer for converting pressure into an electrical analog quantity, and reference numeral 7 is a thin pipe for introducing Caro pressure air into the transducer 6.

Figure 2 is an external view of an uninvented wristwatch with a blood pressure measuring device. 9 is a band to be worn on the arm, but the band also serves as an air bag and has a built-in small microphone to detect pulse sounds. .

10 is a valve hole for an air conductor, and 11 is a fastener or metal fitting for attaching the band to the arm.

FIG. 3 is a diagram showing the wristwatch with a blood pressure monitor of the present invention worn on the wrist, where 14 is a blood pressure display section, 12 is a compressed air delivery pump, and 13 is an air vent.

FIG. 4 is a circuit block diagram of the blood pressure measuring section.

The wristwatch with the blood pressure measuring device of the present invention as shown in FIG.
Place the device on your arm as shown in the picture.

Normally, as a digital wristwatch, the time, such as 12:30, is displayed on the time display section 16 as shown in the figure.

When the user wants to measure blood pressure, connect the air delivery pump 12 to the air valve hole 10 shown in FIG. is sent and expands, tightening the arm in the state shown in Figure 3.

At this time, the air pressure is applied to the transducer by a thin pipe 7 leading to the transducer in FIG. 1, and the air pressure is converted into an analog voltage by the transducer user.

In FIG. 4, the voltage is converted into a frequency as a digital quantity by an A, D-converter using the frequency from the watch frequency divider circuit.

The frequency is counted by the counter 23 and sent to the decoder 2.
4, the air pressure inside the air bag 9, which also serves as a band, is displayed moment by moment on the display device 14.6 On the other hand, the pulse sound for surface pressure measurement is a voltage analogue amount due to changes in air pressure due to pulsations applied to the transducer. The pulsations directly affect the amplifier 26
The speaker 8 which is amplified by the sound of the speaker 8
It can also be used as a microphone.

Instead of a speaker, a sounding body to which a piezoelectric element or the like is attached may be used.

When measuring blood pressure, the air pump 12 sends air to the air bag 9 which also serves as a band, and the air is gradually removed from the air vent 13 while listening to the pulse sound from the speaker 8.
The highest and lowest blood pressure values are measured while reading the digital value 14 displayed on the face of the watch.

In this embodiment, a method was adopted in which the pulse sound was played using a speaker, which is a method generally used for blood pressure measurement. The blood pressure can be measured by providing a display section 15 that blinks with the pulse sound, adjusting the air pressure while watching the blinking status of the display section 15, and reading the number 14 displayed on the display surface.

Furthermore, it is also possible to provide a margin in the band portion that also serves as an air pressure bag so that blood pressure can be measured at the upper arm, which is the usual position for measuring blood pressure.

Furthermore, it can be equipped with an alarm device that sets and memorizes the daily measurement time, sounds a speaker or a sounding device at the set time, and notifies the measurement time. Various applications are also possible, such as being able to be incorporated into a system that sends data to health care centers.

As described above, by using the wristwatch of the present invention that can also measure blood pressure, the user can measure blood pressure at any time and at any time, and can predict dangerous medical conditions such as heart disease and cerebral hemorrhage in advance. It is extremely effective for daily health management.
