Description

{WRIST-MOUNT BLOOD PRESSURE MONITOR}

The present invention relates to a blood pressure monitor for measuring blood pressure. More particularly, the present invention relates to a blood pressure monitor for wrist wearing, which is capable of measuring blood pressure conveniently while being worn on the wrist at all times, The present invention relates to a blood pressure monitor.

Generally, the blood pressure is measured as the blood pressure on the wall of the blood vessel, and the heart repeats shrinkage and relaxation about 60 to 80 times per minute. When the heart contracts and pushes out the blood, the pressure on the blood vessel is called 'contracting blood pressure' and is called 'hypertension' because it is the highest. In addition, when the heart relaxes and receives blood, the pressure maintained in the blood vessel is called 'relaxed blood pressure' and the lowest is called 'the lowest blood pressure'.

The normal blood pressure of a normal person is 120 mmHg in shrinking blood pressure and 80 mmHg in relaxed blood pressure. More than 1 out of 4 adults in Korea are hypertensive and this rate is increasing rapidly after 40 years of age.

The problem of hypertension is that it may cause other complications that may pose a life threatening condition such as eye disease, kidney disease, arterial disease, brain disease, heart disease if left without proper management of hypertension. Therefore, in the case of the above-mentioned complication or the complication, continuous measurement and management of the blood pressure should be performed.

Recently, various kinds of blood pressure measuring devices have been developed in accordance with the growing interest in health.

The blood pressure measurement method includes a Korotkoff sounds method, an oscillometric method, and a tonometric method.

The stethoscope method is a typical pressure measurement method. In the process of decompressing the blood flow by applying sufficient pressure to the body part passing through the arterial blood, the pressure at the moment when the pulse sound is heard for the first time is measured by systolic pressure And the pressure at the moment when the pulsation disappears is measured by diastolic pressure.

The oscillometric method and the tonometric method are applied to a digitized blood pressure measuring device.

The oscillometric method is a method in which the body part through which the arterial blood passes is decompressed at a constant speed so as to block the arterial blood flow as in the stethoscopic method or a pulse wave generated during the pressure step- And measures systolic blood pressure and diastolic blood pressure.

Here, the pressure at the time when the amplitude of the pulse wave is maximum can be measured by the systolic blood pressure or the diastolic blood pressure, and the pressure when the rate of change of the pulse wave amplitude is rapidly changed is measured by the systolic blood pressure or the diastolic blood pressure You may.

In the process of reducing pressure at a constant rate after pressurization, the systolic blood pressure is measured ahead of the moment when the amplitude of the pulse wave is maximum, and the diastolic blood pressure is measured later than the moment when the amplitude of the pulse wave is maximum. On the contrary, in the process of increasing the blood pressure at a constant speed, the systolic blood pressure is measured later than the moment when the amplitude of the pulse wave is the maximum, and the diastolic blood pressure is measured ahead of the moment when the amplitude of the pulse wave is maximum.

Next, in the tonometric method, a constant pressure of a magnitude not blocking the blood flow of the artery is applied to the body part, and the blood pressure can be continuously measured using the size and shape of the pulse wave generated at this time.

As described above, the blood pressure monitor for measuring blood pressure is the most basic medical equipment for measuring the blood pressure which is the basis of the health index. In addition, the blood pressure monitor is almost indispensably provided in general hospitals, It is in use.

However, in the case of a conventional blood pressure monitor, when the blood pressure is mostly measured, the blood pressure is measured by winding the blood pressure meter on the upper arm (upper arm or upper arm, part from the shoulder to the elbow) It is not easy to easily measure the blood pressure when desired.

For example, in the conventional oscillometric blood pressure monitor, a product is released only in the form of a forearm, which requires a sphygmomanometer main body and a pressure cuff, a tube plug, an air hose, It is bulky and has a disadvantage in that it is cumbersome to use because there is a lot of preparations in the preparation of the measurement, for example, the air hose must be fitted downward for proper measurement at the time of use or the cuff should be worn 1 to 2 cm above the elbow.

Particularly, since blood pressure varies depending on the body characteristics of the subject, patients having complications in the body need to immediately measure the blood pressure every time the subject feels abnormality in the body and / or the body. The mercury sphygmomanometer and the electronic blood pressure monitor Thereby providing inconvenience to the patients due to the following problems.

First, the mercury sphygmomanometer and the electronic sphygmomanometer use a cuff requiring air injection. However, the cuff has a bulky size, so that it is troublesome for a user to wear it in real time.

In addition, the mercury sphygmomanometer using the pneumatic cuff for a patient who frequently measures the blood pressure frequently has an excessive volume and weight, which makes it difficult for the subject (patient) to carry it all the time. Whenever the blood pressure is measured, There is a hassle to do.

Although there is a pneumatic electronic blood pressure monitor having the same accuracy as the conventional blood pressure monitor described above, when the blood pressure is measured periodically while the patient continues to carry it, the weight is heavy and bulky There is a problem that the behavior of the patient is inconvenient.

In addition, there are non-pressure type electronic blood pressure monitors that measure blood pressure based on various parameters of the wrist or finger tip. However, since it is difficult to accurately specify the parameters and provide them universally, it is necessary to periodically measure an accurate blood pressure It is difficult to apply to patients.

Meanwhile, in recent years, a blood pressure monitor capable of measuring blood pressure by being worn on the wrist is being marketed as a wristwatch type blood pressure monitor.

However, a conventional wristwatch blood pressure monitor is simply called a wristwatch because it measures blood pressure by wearing it on the wrist, but it is practically not as bulky as a wrist watch.

In other words, a conventional wristwatch type blood pressure meter is a form in which a conventional blood pressure meter is reduced in size so that it can be applied to the wrist instead of the upper arm because the pressure cuff is closed and the pump is operated to measure the blood pressure.

The operation of the wristwatch blood pressure monitor 1 of this embodiment configured as described above is as follows.

The process of measuring the blood pressure using the wristwatch blood pressure monitor 1 of this embodiment is the same as that of the first embodiment described above.

In other words, the systolic blood pressure and the diastolic blood pressure are measured by sensing the pulse wave generated during the process of reducing the blood pressure of the radial artery by passing the radial artery through the sealed air chamber 120 sufficiently.

Instead, the wristwatch blood pressure monitor 1 of this embodiment differs from the above-described [Embodiment 1] in terms of the action before and after the blood pressure measurement in the following aspects.

First, it is important to measure and record at the same time every day in order to know the trend of the ever-changing blood pressure. Since the blood pressure monitor of this embodiment is a wristwatch type and can always wear, it is very useful for measurement and recording at the same time every day.

In addition, the blood pressure monitor of the present embodiment can have an alarm function, and by alarming at a preset time for blood pressure measurement, it is possible to easily measure and record and record at the same time or at a predetermined time every day, The measurement and the management of the blood pressure can be performed.
