Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a blood pressure monitor,

The present invention is characterized in that the cuff is of the bracelet type and the air bag is positioned only in a part of the upper part of the cuff and a part of the lower part of the cuff and is located in the part corresponding to the radial artery, and only the upper and lower cuffs of the radial artery are swollen, The present invention relates to a wrist blood pressure monitor which reduces noises caused by movement, which makes it possible to reduce noise caused by a signal line shake and accurately detect blood pressure.

Arteriosclerosis is a phenomenon in which cholesterol and triglycerides are deposited and the elasticity of the blood vessels is decreased and the arteries become narrowed as thrombosis occurs. This is a kind of aging phenomenon, but it appears in most elderly people although there is a difference in degree.

Atherosclerosis test is a test to assess arterial stiffness and stenosis by measuring blood pressure difference and arterial pressure in upper and lower extremities. For this inspection, as shown in Fig. 1, four cuffs for measuring the blood pressure mounted on the upper and lower limbs and three electrocardiogram electrodes for detecting the electrocardiogram are used.

 Patients should wear cuffs and electrocardiogram electrodes and take a fixed posture during the measurement time. If the cuff is not fixed, it may cause measurement error even with fine movement.

 Further, the number of cuffs and electrodes to be connected is large, which causes inconvenience to the patient, and it is troublesome for the tester to also mount the cuffs and the electrocardiogram electrodes.

Therefore, a means for fixing the cuff more reliably is desired.

Also, a method of coupling an ECG electrode with a cuff mounted on the upper side is desired.

However, since normal electrocardiogram electrodes affect the cuff, an electrocardiogram electrode is needed to reduce this problem.

In particular, the structure of a conventional wrist blood pressure monitor is a structure in which the body is supported only with a cuff (cuff) and the wrist is pressed at the same time. This structure shows a serious signal distortion due to the cuff and a linear compression through the cuff And it is also difficult to measure with a strong pressure.

  Therefore, there is a need for a wrist and ankle fastening cuff for atherosclerosis measurement that is more securely fastened to the limb, reduces noise due to motion or signal line blur, and is easier to use.

The elasticized rubber ring cuff for blood pressure measurement of Korean Patent No. 10-1350935 includes an annular rubber ring which can be worn on the wrist or ankle and an elastic coil spring which is embedded in the tubular rubber ring in the length range of the rubber ring A pressure sensor for measuring the blood pressure and a sending circuit for sending the measurement data to the outside. Normally, a rubber ring cuff is worn on the wrist or ankle, and when the blood pressure is measured, a rubber ring cuff is placed on the measurement site The cuff is fixed with an elastic supporting force, and the blood pressure is measured by a pressure sensor and transmitted to an external blood pressure monitor to analyze and display the measurement result.

However, in the case of Korean Patent No. 10-1350935, the blood pressure is measured using the elasticity of the coil spring mounted on the rubber ring, instead of measuring the blood pressure by pressing or depressurizing the air bag of the cuff mounted on the wrist, The accuracy of the apparatus is degraded.

Therefore, it is possible to measure the blood pressure by pressing or depressurizing the bladder, more reliably fixed to the limb, reducing noise due to movement or signal line blurring, making it easier and easier to use, A wrist and ankle ankle cuff for measurement is also required.

In another prior art, Korean Patent No. 10-0855042 discloses a method of measuring the radial artery pulse wave and measuring the continuous blood pressure value and arterial elasticity of the radial artery and the radial artery from the body, The present invention relates to a device for measuring non-invasive continuous blood pressure and arterial elasticity and a method for measuring the arterial elasticity by using at least one pulse wave signal detected from a body by attaching the device to a radial or carotid artery region of a body without using a pressure cuff, An analog signal processing unit including a sensor unit for detecting an absorption / reflection signal and an electrocardiogram signal, a control unit including an A / D conversion and a digital signal processing unit, a display unit, and an interface unit for communication with an external device.

However, as described in Korean Patent No. 10-0855042, a method of estimating blood pressure using a pulse wave signal without using a cuff is generally inaccurate. Also, the method of measuring the blood pressure using only the pressure sensor without pressurization is also less accurate.

Therefore, a blood pressure measuring device including an electrocardiogram electrode for measuring an electrocardiogram (ECG) without being affected by a cuff is required, and a blood pressure measuring device for measuring an atherosclerosis degree is required. For accurate and precise ECG measurement, There is a demand for a blood pressure measuring device having three or more electrocardiogram electrodes.

 In particular, a wrist type blood pressure monitor integrated with an electrocardiogram electrode, in which an electrocardiogram electrode is made of a conductive fabric and placed on the upper part of a cuff for measuring blood pressure, is desired.
