Abstract

The present invention discloses a portable wrist blood pressure gauge which is worn on a wrist and can always be portable. A portable wrist blood pressure gauge, according to one embodiment of the present invention, comprises: a wrist strap; and a display unit for outputting the blood pressure value of a wearer, wherein the display unit is provided in the wrist strap and worn on a wrist of the wearer by means of the wrist strap. In addition, the wrist strap comprises: a base strap on which the display unit is mounted; an airbag provided in the base strap so as to pressurize the wrist; and a pumping chamber, provided in the base strap with the airbag, which is constricted by an external pressure while supplying air to the airbag and is expanded by its own elasticity to draw in external air. According to the present invention, the blood pressure gauge is worn at all times like a wrist watch so that blood pressure can be conveniently measured, whenever necessary, in a continuous motion with one hand only. Moreover, since the pumping chamber for filling the airbag draws in air by its own elasticity, mechanical or electrical devices for filling the airbag, such as a pump or a motor, are not required, thereby simplifying the structure thereof and reducing manufacturing costs.

일반적으로, 혈액이 혈관의 벽에 미치는 압력을 잰 것을 혈압이라고 하며, 심장은 1분에 약 60 내지 80회 수축과 이완을 반복한다. 심장이 수축하여 피를 밀어낼 때 혈관에 미치는 압력을 '수축혈압'이라고 하며 가장 높기 때문에 '최고혈압'이라고 한다. 또한, 심장이 이완되면서 혈액을 받아들일 때 혈관 압력을 '이완혈압'이라고 하며 가장 낮기 때문에 '최저혈압'이라고 한다.In general, the pressure on the walls of blood vessels is called blood pressure, and the heart repeats contraction and relaxation about 60 to 80 times per minute. When the heart contracts and pushes blood, the pressure on the blood vessels is called 'constrictive blood pressure' and because it is the highest, it is called 'high blood pressure'. In addition, when the heart relaxes, the blood pressure when receiving blood is called 'relaxation blood pressure' and because it is the lowest, it is called 'lowest blood pressure'.
보통 정상인의 혈압은 수축혈압이 120mmHg이고, 이완혈압은 80mmHg을 나타낸다. 우리나라 성인의 4명 중 1명 이상이 고혈압에 해당되며 40세 이후부터는 이 비율이 급격히 증가하는 추세를 나타내고 있으며, 저혈압으로 분류된 환자도 있다.Normal blood pressure of normal people is 120mmHg systolic blood pressure, the relaxation blood pressure is 80mmHg. At least one in four Korean adults is hypertension, and since the age of 40, the rate has increased rapidly, and some patients have been classified as hypotension.
상기 고혈압이 문제가 되는 것은 고혈압을 적절히 관리하지 않고 방치할 경우 안질환, 신장질환, 동맥질환, 뇌질환, 심장질환과 같은 생명에 위협을 가할 수 있는 다른 합병증들의 원인이 될 수 있기 때문이다. 따라서, 상기 합병증의 위험이 있거나 합병증을 가진 환자의 경우 지속적인 혈압의 측정과 관리가 이루어져야 한다.The high blood pressure is a problem because it can cause other complications that can pose a life threat, such as eye disease, kidney disease, arterial disease, brain disease, heart disease if left uncontrolled. Therefore, patients who are at risk of or have complications should have continuous blood pressure measurement and management.
상술한 고혈압 등 성인병 관련 질환과 건강에 대한 관심이 증가함에 따라 다양한 종류의 혈압 측정 장치가 개발되고 있다. Various types of blood pressure measuring apparatuses have been developed as the interest in the diseases and health related to adult diseases such as high blood pressure is increased.
혈압 측정 방식에는 청진(Korotkoff sounds) 방식, 오실로메트릭(oscillometric) 방식, 및 토노메트릭(tonometric) 방식 등이 있다. Blood pressure measurement methods include a stethoscope (Korotkoff sounds), an oscillometric (oscillometric), and tonometric (tonometric) method.
상기 청진 방식은 전형적인 압력 측정 방식으로, 동맥혈이 지나는 신체 부위에 충분한 압력을 가해 혈액의 흐름을 차단한 후 감압하는 과정에서, 처음으로 맥박 소리가 들리는 순간의 압력을 수축기 혈압(systolic pressure)으로 측정하고, 맥박 소리가 사라지는 순간의 압력을 이완기 혈압(diastolic pressure)으로 측정하는 방법이다.The auscultation method is a typical pressure measuring method, in which a sufficient pressure is applied to a part of the body through which arterial blood flows to block the flow of blood and then decompress the blood pressure, and the pressure of the first pulse sound is measured by systolic pressure. The pressure at the moment the pulse disappears is measured by diastolic pressure.
상기 오실로메트릭 방식과 토노메트릭 방식은 디지털화된 혈압 측정 장치에 적용되는 방식이다. The oscillometric method and the tonometric method are applied to the digitized blood pressure measuring device.
상기 오실로메트릭 방식은 청진 방식과 마찬가지로 동맥의 혈류가 차단되도록 동맥혈이 지나는 신체 부위를 충분히 가압한 후 일정 속도로 감압하는 과정, 또는 상기 신체 부위를 일정 속도로 증압되게 가압하는 과정에서 발생하는 맥파를 감지하여 수축기 혈압과 이완기 혈압을 측정한다. The oscillometric method is similar to the stethoscope method to pressurize the body part through which arterial blood flows so that the blood flow of the artery is sufficiently depressurized at a constant speed, or pressurizes the pulse wave generated in the process of pressurizing the body part at a constant speed. Detect and measure systolic and diastolic blood pressure.
여기서, 맥파의 진폭이 최대인 순간과 비교하여 일정 수준인 때의 압력을 수축기 혈압 또는 이완기 혈압으로 측정할 수도 있고, 상기 맥파 진폭의 변화율이 급격히 변화되는 때의 압력을 수축기 혈압 또는 이완기 혈압으로 측정할 수도 있다. Here, the pressure at a constant level may be measured by systolic blood pressure or diastolic blood pressure as compared with the moment when the amplitude of the pulse wave is maximum, and the pressure when the rate of change of the pulse wave amplitude changes rapidly is measured by systolic blood pressure or diastolic blood pressure. You may.
그리고, 가압 후 일정 속도로 감압하는 과정에서는 상기 맥파의 진폭이 최대인 순간보다 앞서서 수축기 혈압이 측정되고, 상기 맥파의 진폭이 최대인 순간보다 나중에 이완기 혈압이 측정된다. 이와 반대로, 일정 속도로 증압하는 과정에서는 상기 맥파의 진폭이 최대인 순간보다 나중에 수축기 혈압이 측정되고, 상기 맥파의 진폭이 최대인 순간보다 앞서서 이완기 혈압이 측정된다. In the process of depressurizing at a constant speed after pressurization, systolic blood pressure is measured before the moment when the amplitude of the pulse wave is maximum, and 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 pressure at a constant speed, systolic blood pressure is measured later than the moment when the amplitude of the pulse wave is maximum, and diastolic blood pressure is measured before the moment when the amplitude of the pulse wave is maximum.
다음으로, 상기 토노메트릭 방식은 동맥의 혈류를 완전히 차단하지 않는 크기의 일정 압력을 신체 부위에 가하고, 이때 발생되는 맥파의 크기 및 형태를 이용하여 연속적으로 혈압을 측정할 수 있는 방식이다.Next, the tonometric method is a method in which a certain pressure of a size that does not completely block the blood flow of the arteries is applied to the body part, and the blood pressure is continuously measured using the size and shape of the pulse wave generated at this time.
상기와 같이 혈압을 측정하는 혈압계는 건강지수의 기본이 되는 혈압을 측정하기 위한 가장 기본적인 의료장비로서, 일반 병의원에는 거의 필수적으로 구비되어 있을 뿐만 아니라 가정이나 스포츠센터 등에서도 개인의 혈압 측정을 위해 많이 사용하고 있는 실정이다.Sphygmomanometer to measure blood pressure as described above is the most basic medical equipment for measuring blood pressure, which is the basis of the health index, which is almost indispensable in general hospitals, as well as for home or sports centers to measure the blood pressure of individuals I'm using it.
그러나, 기존의 혈압계의 경우, 대부분 혈압측정이 필요할 때마다 상박(위팔 또는 상완, 어깨에서 팔꿈치까지의 부분)에 혈압계를 감아서 혈압을 측정하는 팔뚝형으로 제품이 출시되어 있어서 휴대하기가 불편하고 사용에 있어서도 원하는 때에 손쉽게 혈압을 측정하기가 용이하지 않은 실정이다.However, most conventional blood pressure monitors have a forearm type that measures blood pressure by wrapping the blood pressure monitor around the upper arm (upper arm or upper arm, shoulder to elbow) whenever the blood pressure measurement is necessary, which is inconvenient to carry. Even in use, it is not easy to measure blood pressure easily when desired.
예컨대, 기존의 오실로메트릭스 방식의 혈압계의 경우, 팔뚝형으로만 제품이 출시되어 있는데, 팔뚝에 감아서 압박하기 위한 혈압계본체와, 압박커프, 튜브플러그, 에어호스 등이 필요하므로, 구성이 복잡하고 부피가 크며, 사용시에 올바른 측정을 위해서는 에어호스가 아래를 향하도록 끼워야 한다거나, 커프를 팔꿈치 1~2cm 위로 착용해야 하는 등 측정 준비 과정에 준비 사항도 많아 사용상 번거롭다는 단점이 있다.For example, in the case of the conventional oscillometric blood pressure monitor, the product is released only in the forearm type, and the configuration is complicated because a blood pressure monitor body for compressing the forearm and a compression cuff, a tube plug, and an air hose are required. It is bulky and has a disadvantage in that it requires a lot of preparations in the preparation process for measurement such as air hose should be inserted downward for proper measurement, or cuff should be worn over 1 ~ 2cm for use.
특히, 혈압은 피검자의 신체특성에 따라 변화 정도가 상이하므로, 체내에 합병증이 있는 환자들은 주기적으로 및/또는 신체에 이상을 느낄 때마다 즉시 혈압을 측정할 필요성이 있는데, 수은 혈압계와 전자혈압계는 후술하는 문제점으로 인하여 상기 환자들에게 불편함을 제공한다.In particular, since blood pressure varies according to the physical characteristics of the subject, patients with complications in the body need to measure blood pressure immediately at regular intervals and / or whenever there is an abnormality in the body. The following problems provide inconvenience to the patients.
우선, 상기 수은 혈압계와 전자 혈압계는 공기 주입을 필요로 하는 커프를 사용하게 되는데, 상기 커프는 부피가 커서 사용자가 실시간으로 착용하기 번거로운 문제점이 있다.First, the mercury sphygmomanometer and the electronic sphygmomanometer use a cuff requiring air injection, and the cuff has a problem that it is cumbersome for a user to wear in real time.
또한, 자주 혈압을 측정해야 하는 환자에게 상기 공압식 커프를 이용한 수은혈압계는 부피 및 무게가 과도하여, 피검자(환자)가 휴대하고 다니기에 불편함과 무리함이 있고, 혈압을 측정할 때마다 매번 상기 혈압계를 탈부착해야 하는 번거로움이 있다.In addition, the mercury sphygmomanometer using the pneumatic cuff to the patient who needs to measure blood pressure frequently is excessive in volume and weight, there is inconvenience and unreasonable to carry the subject (patient), and the above each time to measure the blood pressure There is a hassle to detach the blood pressure monitor.
그리고, 상술한 종래의 혈압계와 동일한 정밀도를 가지는 공압식 전자혈압계가 있지만, 환자가 계속하여 휴대하면서 주기적으로 혈압을 측정해야 하는 경우에 적용될 경우, 전기식 펌프와 공기 주입식 커프를 사용하기 때문에 무게가 무겁고 부피가 커 환자의 거동이 불편해지는 문제점이 있다.In addition, although there is a pneumatic electronic blood pressure monitor having the same precision as the conventional blood pressure monitor described above, when applied to the case where the patient needs to periodically carry out blood pressure measurement, the weight is heavy and bulky because it uses an electric pump and an air-injected cuff. There is a problem that the behavior of the patient becomes uncomfortable.
그 외에, 손목이나 손끝의 맥박과 다양한 파라메터들을 근거로 혈압을 측정하는 비가압식 전자 혈압계들도 존재하고 있으나, 상기 파라메터들을 정확하게 특정하여 범용적으로 제공하기 어려워 정밀도가 낮아 정확한 혈압을 주기적으로 측정해야 하는 환자들에게 적용하기 어렵다.In addition, there are non-pressure electronic sphygmomanometers that measure blood pressure based on the pulse of the wrist or fingertip and various parameters, but it is difficult to provide the parameters precisely and universally. It is difficult to apply to patients.
한편, 최근에는 손목시계처럼 손목에 착용하여 휴대하면서 혈압을 측정할 수 있는 혈압계가 손목 혈압계 또는 손목착용 혈압계 또는 손목시계형 혈압계 등의 이름으로 개발되고 있다.On the other hand, recently, a blood pressure monitor capable of measuring blood pressure while being worn on a wrist like a wrist watch has been developed under the name of a wrist blood pressure monitor, a wrist worn blood pressure monitor, or a wrist watch type blood pressure monitor.
그러나, 기존의 손목 혈압계는 단순히 손목에 착용해서 혈압을 측정하기 때문에 손목시계형이라 불리기는 하지만, 실질적으로는 손목에 시계처럼 차고 다닐 정도로 부피가 작지 않은 실정이다. 즉, 기존의 손목 혈압계는 상박 대신에 손목에 적용할 수 있도록 사이즈만 약간 줄어든 형태라고 할 수 있으며, 기타 다른 손목 혈압계 역시 손목 가압을 위해 기계식/전자식 펌핑 장치가 구비되어 구조적으로 복잡하며 조작 및 작동이 어려우며 고장이 쉽게 발생하고 제조비용이 증가하는 등의 문제가 있다.However, the conventional wrist sphygmomanometer is called a wristwatch type because it is simply worn on the wrist to measure blood pressure, but in reality, the wrist sphygmomanometer is not small enough to carry a wrist like a watch. In other words, conventional wrist sphygmomanometer can be said to be slightly reduced in size so that it can be applied to wrist instead of upper arm. Other wrist sphygmomanometer is equipped with mechanical / electronic pumping device for pressurizing wrist, and it is structurally complicated and operated and operated. This is difficult and there are problems such as failure easily occur and manufacturing cost increases.
본 발명은 상술한 문제점을 해결하기 위해 제안된 것으로서, 손목시계처럼 한쪽 팔의 손목에 착용하여 휴대하면서 반대측 손의 단순 동작 예를 들면 한 손의 단계적인 연속 동작으로 혈압을 용이하게 측정할 수 있으며, 더 나아가 구조적으로 단순화된 손목 혈압계를 제공하는 데 그 목적이 있다.The present invention has been proposed to solve the above problems, and can be easily measured blood pressure by wearing the wrist of one arm, such as a wristwatch, the simple operation of the other hand, for example, stepwise continuous movement of one hand. In addition, the aim is to provide a structurally simplified wrist blood pressure monitor.
본 발명은 손목에 착용되어 상시 휴대 가능한 휴대형 손목 혈압계로서, 본 발명의 일 실시 예에 따른 휴대형 손목 혈압계는: 손목 스트랩(Wrist Strap); 그리고 상기 손목 스트랩에 구비되어 상기 손목 스트랩에 의해 상기 손목에 피착되며, 착용자의 혈압을 표시하는 디스플레이 유닛을 포함하여 구성된다. 그리고, 상기 손목 스트랩은; 상기 디스플레이 유닛이 탑재되는 베이스 스트랩; 상기 손목을 가압하도록 상기 베이스 스트랩에 구비되는 에어백; 그리고 상기 에어백과 함께 상기 베이스 스트랩에 구비되며, 외압에 의해 수축되면서 상기 에어백에 공기를 공급하고, 자체 탄성에 의해 팽창해서 외부 공기를 흡입하는 펌핑 챔버를 포함하여 구성된다.The present invention is a portable wrist sphygmomanometer worn on the wrist and portable at all times, the portable wrist sphygmomanometer according to an embodiment of the present invention includes: a wrist strap; And a display unit provided on the wrist strap and attached to the wrist by the wrist strap and displaying a blood pressure of the wearer. And, the wrist strap is; A base strap on which the display unit is mounted; An airbag provided in the base strap to pressurize the wrist; And a pumping chamber provided on the base strap together with the air bag, supplying air to the air bag while being contracted by external pressure, and expanding by self elasticity to suck external air.
상기 손목 혈압계가 손목에 착용된 상태를 기준으로, 상기 에어백의 적어도 일부분이 요골 동맥이 지나는 부위를 덮도록 손목의 안쪽에 위치할 때, 상기 펌핑 챔버의 적어도 일부분은 손목의 바깥쪽인 손목의 등에 배치되는 것을 특징으로 한다. 예를 들어, 상기 펌핑 챔버의 중간에서 상기 에어백의 중간까지의 거리는 상기 손목 혈압계의 둘레길이의 1/4 내지 1/2이다. 따라서, 사용자가 상기 손목 혈압계를 한쪽 팔의 손목에 착용하여 휴대하면서 활동하는 중에 혈압 체크가 필요하면, 다른 한손의 손가락으로 상기 펌핑 챔버를 눌러서 상기 에어백을 충진하고 펌핑 챔버를 누른 손을 그대로 말아서 오므리면, 상기 에어백이 손바닥에 의해 가압됨으로써 혈압을 체크할 수 있으므로, 단순한 동작으로 쉽게 혈압 측정이 가능하다. Based on the wrist sphygmomanometer worn on the wrist, when at least a portion of the airbag is positioned inside the wrist to cover the area through which the radial artery passes, at least a portion of the pumping chamber is placed on the back of the wrist, which is outside of the wrist. It is characterized in that the arrangement. For example, the distance from the middle of the pumping chamber to the middle of the airbag is 1/4 to 1/2 of the circumferential length of the wrist blood pressure monitor. Therefore, if a user needs to check the blood pressure while carrying the wrist sphygmomanometer on the wrist of one arm and performing the activity, the user presses the pumping chamber with the finger of the other hand to fill the air bag and rolls the pumping chamber as it is. If the airbag is pressed by the palm of the hand, it is possible to check the blood pressure, it is possible to measure blood pressure easily with a simple operation.
그리고, 상기 손목 혈압계가 손목에 착용된 상태를 기준으로, 상기 에어백의 적어도 일부분이 요골 동맥이 지나는 부위를 덮도록 손목의 안쪽에 위치할 때, 상기 펌핑 챔버의 적어도 일부분이 손목의 안쪽에 배치되도록 상기 펌핑 챔버가 상기 에어백에서 자뼈(척골)방향에 구비될 수도 있다. 예를 들어, 상기 펌핑 챔버의 중간에서 상기 에어백의 중간까지의 거리가 상기 손목 혈압계의 둘레길이의 1/8 내지 3/8이다. 이러한 경우, 사용자가 상기 손목 혈압계를 한쪽 팔의 손목에 착용하여 휴대하면서 활동하는 중에 혈압 체크가 필요하면, 다른 한손의 손바닥으로 상기 펌핑 챔버를 눌러서 상기 에어백을 충진하고 펌핑 챔버를 누른 손바닥을 굴리면, 상기 에어백이 동일 손바닥의 다른 부분(상대적으로 윗부분)에 의해 가압됨으로써 혈압을 체크할 수 있으므로, 단순한 동작으로 쉽게 혈압 측정이 가능하다.And at least a portion of the pumping chamber is disposed inside the wrist when at least a portion of the airbag is positioned inside the wrist to cover a portion through which the radial artery passes, based on a state where the wrist sphygmomanometer is worn on the wrist. The pumping chamber may be provided in the vertebral (vertebral) direction of the airbag. For example, the distance from the middle of the pumping chamber to the middle of the airbag is 1/8 to 3/8 of the perimeter of the wrist blood pressure monitor. In this case, if the user needs to check the blood pressure while carrying the wrist sphygmomanometer on the wrist of one arm and performing the activity, the user presses the pumping chamber with the palm of the other hand to fill the air bag and rolls the palm pushing the pumping chamber. Since the airbag is pressurized by another part (relatively upper part) of the same palm, the blood pressure can be checked, and thus blood pressure measurement can be easily performed with a simple operation.
상기 에어백과 상기 펌핑 챔버는 제1체크밸브에 의해 연결되고; 상기 펌핑 챔버의 일측에는 상기 외부 공기를 상기 펌핑 챔버에 공급하는 제2체크밸브가 연결되며; 상기 에어백의 일측에는 상기 에어백의 감압을 위한 배기 밸브가 연결된다.The airbag and the pumping chamber are connected by a first check valve; A second check valve connected to one side of the pumping chamber to supply the external air to the pumping chamber; One side of the airbag is connected to the exhaust valve for decompression of the airbag.
그리고, 상기 디스플레이 유닛은 회로 기판을 포함하며; 상기 에어백에는 상기 에어백의 압력을 감지해서 상기 회로 기판에 압력 신호를 전달하는 압력 센서가 연결된다. 상기 회로 기판은, 상기 에어백을 기준으로 상기 펌핑 챔버의 반대측에 구비되나 이에 한정되는 것은 아니다.And the display unit comprises a circuit board; The airbag is connected to a pressure sensor that senses the pressure of the airbag and transmits a pressure signal to the circuit board. The circuit board is provided on the opposite side of the pumping chamber based on the airbag, but is not limited thereto.
본 발명의 손목 혈압계에 의한 효과는 다음과 같다.Effects of the wrist blood pressure monitor of the present invention are as follows.
먼저, 본 발명에 의하면, 혈압계를 손목시계처럼 상시 착용하여 필요할 때마다 편리하게 혈압을 측정할 수 있으며, 에어백 충진을 위한 펌핑 챔버가 자체 탄성력에 의해 원래의 형상으로 복원되면서 공기를 흡입하므로, 에어백 충진을 위한 펌프나 모터 등의 기계/전자 장치가 필요없고 구조적으로 단순화될 수 있으며, 제조비용이 절감될 수 있으며, 공기 충진을 위해 별도의 에너지원을 소모하지 않으므로 배터리 용량에 대한 부담을 줄일 수 있다.First, according to the present invention, the blood pressure monitor can be worn at all times like a wrist watch, and the blood pressure can be conveniently measured whenever necessary. Since the pumping chamber for airbag filling is restored to its original shape by its elastic force, the airbag No need for mechanical / electronic devices such as pumps or motors for filling, structural simplification, manufacturing costs can be reduced, and no additional energy source is consumed for air filling, reducing the burden on battery capacity. have.
그리고, 본 발명에 의하면, 에어백 내부의 공기압을 쉽게 증가시킬 수 있으며, 에어백 충진을 위한 펌프의 조작과 손목의 가압이 한 손 크기의 범위 더 좁게는 손바닥 크기의 범위 내에서 한 손의 연속 동작에 의한 단순 터치만으로 수행될 수 있으므로, 혈압계의 조작이 용이하고 정확한 측정이 가능하다.In addition, according to the present invention, it is possible to easily increase the air pressure inside the airbag, the operation of the pump for filling the airbag and pressurization of the wrist narrower than the size of one hand size to the continuous operation of one hand within the palm size range Since it can be performed only by a simple touch, the operation of the blood pressure monitor is easy and accurate measurement is possible.
또한, 본 발명에 의하면, 주기적으로 혈압을 측정해야 하는 피검자의 거동에 방해가 되지 않는 간편한 혈압 측정 장치의 제공이 가능하므로, 혈압을 측정하는 피검자에게 사용상의 편리함을 제공하게 된다.In addition, according to the present invention, since it is possible to provide a simple blood pressure measuring device that does not interfere with the behavior of the test subject to periodically measure the blood pressure, it provides convenience for use to the subject measuring blood pressure.
그리고, 항상 변하는 혈압의 추세를 알기 위해서는 매일 같은 시간에 주기적으로 혈압을 측정을 하고 그 수치를 기록하는 것이 중요한데, 본 발명에 의하면 손목시계형으로서 항시 착용하는 것이 가능하여, 매일 같은 시간에 측정을 하고 기록하는데 매우 유용하며, 알람이 구비될 경우 특히 혈압 측정시기를 놓치지 않고 규칙적으로 혈압을 측정하는데 매우 유리하다.In addition, in order to know the trend of blood pressure that changes all the time, it is important to periodically measure the blood pressure at the same time every day and record the numerical value. According to the present invention, it is possible to always wear it as a watch type, and to measure the same time every day. It is very useful for recording and recording, and when an alarm is provided, it is very advantageous to measure blood pressure regularly, especially without missing a blood pressure measurement time.
또한, 본 발명에 의하면, 측정된 혈압 데이터를 무선통신유닛을 통해 주치의 혹은 전문의 등에게 보내어 분석하는데 활용할 수 있으므로, 고혈압, 당뇨병, 간장 장애, 동맥 경화, 혈액순환의 말초신경 장애 등이 있는 환자들에게 있어 특히 효율적인 혈압의 관리가 이루어질 수 있다.In addition, according to the present invention, since the measured blood pressure data can be utilized to send to the doctor or specialist through the wireless communication unit for analysis, patients with hypertension, diabetes mellitus, hepatic disorders, arteriosclerosis, peripheral nerve disorders of blood circulation, etc. In particular, effective blood pressure management can be achieved.

More specifically, the wrist strap 110 includes a base strap 111, an airbag 112, and a pumping chamber 113. The base strap 111 is a base tissue, that is, a base tissue of the wrist strap 110, and the display unit 120 is mounted on the base strap 111.
본 실시 예에서, 상기 손목 혈압계(100)은 특정 위치에 별도의 체결부없이 연속적으로 이어지는 폐루프 구조의 링 타입이다. 예를 들면, 상기 손목 스트랩(110)이 탄력적으로 벌어질 수 있는 일체형 밴드구조, 즉 외력에 의해 넓게 확장될 수 있는 탄성 손목 밴드로 구성될 수 있다. 물론, 후술되는 실시 예(제3실시 예)와 같이 손목 스트랩이 분리 가능한 구조 즉 분할 가능한 구조로 이루어져서 피검자의 손목 굵기에 맞게 조일 수 있는 손목 스트랩도 가능하다.In the present embodiment, the wrist sphygmomanometer 100 is a ring type of closed loop structure continuously connected without a separate fastening portion at a specific position. For example, the wrist strap 110 may be composed of an integral band structure that can be elastically opened, that is, an elastic wrist band that can be widely extended by an external force. Of course, the wrist strap that can be tightened according to the thickness of the subject's wrist is also possible because the wrist strap is made of a detachable structure, that is, a split structure, as in the following embodiment (third embodiment).
그리고, 상기 에어백(112)은 사용자의 손목을 가압하도록 상기 베이스 스트랩(111)에 구비되며, 상기 에어백(112)의 내부에는 유체 예를 들면 공기의 충진 공간이 형성된다. In addition, the airbag 112 is provided in the base strap 111 so as to press the user's wrist, the air bag 112 is formed inside the air bag 112, for example, a fluid filling space.
다음으로, 상기 펌핑 챔버(113)는 상기 에어백(112)에 공기를 충진시키는 데 사용되는 구성으로서, 상기 에어백(112)과 함께 상기 베이스 스트랩(111)에 구비되어서 상기 에어백(112)과 연결된다. 본 실시 예에서, 상기 펌핑 챔버(113)는 외압에 의해 수축되면서 상기 에어백(112)에 공기를 공급하고, 자체 탄성에 의해 팽창해서 외부 공기를 흡입한다.Next, the pumping chamber 113 is used to fill the airbag 112 with air. The pumping chamber 113 is provided in the base strap 111 together with the airbag 112 and connected to the airbag 112. .

In other words, the airbag 112 and the pumping chamber 113 are arranged to be spaced apart from each other in a line along the longitudinal direction of the base strap 111.
따라서 왼 손목에 상기 손목 혈압계(100)를 착용하고 오른 손의 일부분 예를 들면 오른 손의 손가락으로 상기 펌핑 챔버(113)를 누른 후, 연속 동작으로 오른 손의 다른 부분 예를 들면 손바닥의 중간 영역이나 하부 영역으로 상기 에어백(112)을 눌러서 손목을 가압할 수 있다.Therefore, the wrist blood pressure monitor 100 is worn on the left wrist and the pumping chamber 113 is pressed with a part of the right hand, for example, the finger of the right hand, and then another part of the right hand, for example, the middle region of the palm, in a continuous operation. Alternatively, the wrist may be pressed by pressing the airbag 112 to the lower region.
예를 들어, 상기 손목 혈압계(100)가 양 손목 중 어느 하나의 손목 예를 들어 왼 손목에 착용된 상태를 기준으로, 상기 에어백(112)의 적어도 일부분이 요골 동맥(A)이 지나는 부위를 덮도록 왼손목의 안쪽면에 위치할 때, 상기 펌핑 챔버(113)의 적어도 일부분은 왼 손목의 바깥쪽면 즉 손목의 등에 배치된다. For example, based on a state in which the wrist sphygmomanometer 100 is worn on one of both wrists, for example, the left wrist, at least a portion of the airbag 112 covers a portion where the radial artery A passes. When located on the inner side of the left wrist, at least a portion of the pumping chamber 113 is disposed on the outer side of the left wrist, ie on the back of the wrist.
