Description

{WRIST WEARABLE BLOOD PRESSURE MONITOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a blood pressure monitor for measuring blood pressure, and more particularly, to a portable wrist blood pressure monitor having a structure capable of easily and accurately measuring blood pressure while being worn / carried on the wrist.

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 of the blood pressure 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 ratio is increasing rapidly after age 40, and some patients are classified as hypotension.

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.

BACKGROUND ART [0002] Various kinds of blood pressure measuring devices have been developed as interest in health related diseases and geriatric diseases such as hypertension has increased.

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 the blood pressure is the most basic medical equipment for measuring the blood pressure which is the basis of the health index. It is almost indispensable not only in general medical clinics but also for home blood pressure measurement 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 blood pressure monitor body and a pressure cuff, a tube plug, an air hose, and the like are required for wrapping around the forearm. 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, since the mercury sphygmomanometer using the pneumatic cuff is often excessively bulky and heavy for a patient whose blood pressure is frequently measured, it is inconvenient and inconvenient for the subject (patient) to carry around, and each time the blood pressure is measured, It is troublesome to detach and attach the blood pressure monitor.

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, since the electric pump and the infusion cuff are used, There is a problem that the behavior of the patient becomes uncomfortable.

In addition, there are non-pressure type electronic blood pressure monitors that measure blood pressure based on the pulse of the wrist or the fingertip and various parameters. However, since it is difficult to accurately specify the parameters and provide general purpose, the blood pressure is measured periodically It is difficult to apply to patients with

Meanwhile, in recent years, a blood pressure monitor capable of measuring blood pressure while being worn on a wrist, such as a wristwatch, has been developed in the name of a wrist blood pressure monitor, a wrist blood pressure monitor or a wristwatch blood pressure monitor.

However, the conventional wrist blood pressure monitor simply measures the blood pressure by wearing it on the wrist, so it is called a wristwatch type, but it is practically not so small as to be worn on a wrist. In other words, a conventional wrist blood pressure monitor can be said to be only slightly reduced in size so that it can be applied to the wrist instead of the upper wrist, and other wrist blood pressure monitors are structurally complicated, equipped with a mechanical / electronic pumping device for wrist pressurization, And it is difficult to accurately position the wrist blood pressure monitor at the blood pressure measurement position, so that the accurate blood pressure measurement can not be performed.
