Description

Wrist Sphygmomanometer {WRIST WEARABLE BLOOD PRESSURE MONITOR}

The present invention relates to a wrist sphygmomanometer worn on the wrist to measure blood pressure, and more particularly, to a wrist sphygmomanometer capable of automatically tightening a wrist cuff for wrist compression.

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'.

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.

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.

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.

Blood pressure measurement methods include a stethoscope (Korotkoff sounds), an oscillometric (oscillometric), and tonometric (tonometric) method.

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.

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

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.

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.

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.

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.

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.

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.

For example, a conventional oscillometric blood pressure monitor requires a blood pressure monitor body to be wound around a wrist or forearm, a compression cuff, a tube plug, an air hose, etc., so that the configuration is complicated, bulky, and correct in use. For this purpose, the air hose should be inserted facing down, or in the case of the forearm, the cuff should be worn on the elbow 1-2 cm.

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.

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.

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.

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.

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.

On the other hand, recently, a blood pressure monitor that can measure blood pressure by wearing it 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.

However, the conventional wrist sphygmomanometer is called a wristwatch type because it is simply worn on the wrist to measure blood pressure. However, mechanical / electronic pumping device, or air pump, is provided to pressurize the wrist. This easily occurs and there is a problem such as an increase in manufacturing cost. In addition, the conventional wrist sphygmomanometer should inject air into the wrist compression air bag or air bag every time the blood pressure is measured so that the area passing through the radial artery of the wrist is sufficiently compressed, and the air bag is not sufficiently adhered to the wrist surface so that the blood pressure There is a problem in terms of operating and mechanical aspects, such as a decrease in the accuracy of the measurement and the gradual discharge of air by applying an exhaust valve.
