Description

Blood pressure meter {A device that measures blood pressure}

The present invention relates to a blood pressure measuring device, and more particularly, to a blood pressure measuring device capable of measuring a user's blood pressure and heart rate while measuring the user's blood pressure and heart rate while making it easy to wear by extending the direct hit according to the user's body. .

In general, blood pressure refers to the pressure exerted on the sidewall of an artery when the heart pumps blood, and is determined by the stroke volume and peripheral vascular resistance. Cardiac output is determined by the strength and weakness of the contractile force of the heart, and peripheral vascular resistance is determined by resistance caused by the contraction of arterioles. However, blood pressure commonly referred to as arterial pressure refers to the casual clinic blood pressure measured from the forearm after resting for 5 minutes.

This blood pressure changes according to several conditions. Among them, body position, measurement site, temperature, physical activity, alcohol, and stress have a large influence. Even if these conditions are objectified and careful attention is paid when measuring, there are many differences due to the patient's unique circadian variation, so it can show a difference of 30/10mmHg per day because it is different in the morning and different in the evening. The error caused by blood pressure fluctuations as described above can be avoided as the number of measurements is increased. A 24-hour active blood pressure measurement method, which automatically measures and records, is sometimes used. In addition, as described above, a portable blood pressure monitor is becoming popular so that a user can directly manage his or her blood pressure state by automatically measuring blood pressure and heart rate for 24 hours.

In order to realize this object, the 'blood pressure monitor' of Korean Patent Application Laid-Open No. 2001-0091612 is a portable blood pressure measuring device that can periodically measure blood pressure and heart rate and generate an alarm to notify the user when there is an abnormality in the measured values. has been

The blood pressure detector includes a blood pressure monitor body capable of measuring and displaying blood pressure and heart rate, and a fixing band coupled to the blood pressure monitor body to allow a user to attach the blood pressure monitor to a wrist.

A display window for displaying the measured blood pressure and heart rate is formed on one side of the upper surface of the main body of the blood pressure monitor, and an alarm buzzer and an alarm LED are installed adjacent to the display window. Allow the user to be alerted. In addition, on the other side of the upper surface of the blood pressure monitor main body, adjustment buttons for searching for the blood pressure measurement time and pre-measured values are installed, and on one side of the blood pressure monitor main body, a connection connector for connecting a computer and a blood pressure alarm is formed. It is possible to transmit the measurement data measured by the alarm to the computer.

However, the blood pressure detector having the above-described configuration can be conveniently carried, measure the blood pressure and heart rate at set times, and alert the user when the measured blood pressure value is out of the reference range using the alarm buzzer and the alarm LED. The disadvantage is that it simply transmits an alert in advance.

As a prior document for solving the above-mentioned disadvantages, the 'low cost brake system for stable control of the arm in a blood pressure monitor' of Korean Patent Publication No. 2013-0092056 (published on Aug. 20, 2013) is A low-cost brake system for adjustment, the brake system comprising: a drive motor provided with a rear motor shaft for controlling tightening and loosening of the arm band and a hook; an encoder sensor for detecting rotation of the drive motor; a solenoid valve having a plunger for preventing reverse rotation of the drive motor; a control circuit unit for controlling the components; It is characterized in that it is composed of; a power supply unit that is electrically connected to the blood pressure monitor to supply power.

The prior literature is about measuring blood pressure and heart rate by compressing the user's arm by winding the patient's arm as the pinion gear and the rack coupled to the motor are pressured, but when the user's arm is excessively compressed because the drive motor is not properly controlled. Of course, since it is in a portable form, the user cannot measure blood pressure and heart rate in a comfortable position, so there is a problem in that the blood pressure readings are inaccurate.
