Definitions
- the present invention relates to a sphygmomanometer for blood pressure measurement, and more particularly, a wrist wearing sphygmomanometer, that is, a wristwatch type, which can measure blood pressure conveniently while carrying it on a wrist at all times, which is very simple in structure and precisely measuring blood pressure. It relates to a blood pressure monitor.
- 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.
- the pressure on the blood vessels is called 'constrictive blood pressure' and because it is the highest, it is called 'high blood pressure'.
- the pressure that is maintained in the blood vessels when the heart receives the blood relaxes 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.
- 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.
- 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.
- the pressure at a constant level may be measured by the 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 the systolic blood pressure or diastolic blood pressure. You may.
- 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.
- 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.
- 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 essential in general hospitals as well as home or sports centers, etc. I'm using it.
- the product is released only in the forearm, 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.
- 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.
- the mercury sphygmomanometer using the pneumatic cuff to the patient who needs to measure blood pressure frequently is excessive in volume and weight, it is difficult for the patient (patient) to always carry, and detach the sphygmomanometer every time the blood pressure is measured There is a hassle to do.
- non-pressure electronic sphygmomanometers that measure blood pressure based on various parameters of the pulse of the wrist or fingertips exist, but it is difficult to provide these parameters accurately and universally. Difficult to apply to patients.
- the conventional wristwatch type blood pressure monitor is called a wristwatch type because it is simply worn on the wrist to measure blood pressure, but it is practically not small enough to carry a wrist like a watch.
- the conventional wristwatch type blood pressure monitor is to reduce the size so that the conventional blood pressure monitor can be applied to the wrist instead of the upper arm because the blood pressure is measured by winding the pressure cuff and operating the pump.
