Description

Electronic Sphygmomanometer Using Bluetooth

The present invention relates to an electronic blood pressure monitor using Bluetooth, and more particularly, to an electronic blood pressure monitor using Bluetooth which can provide blood pressure measurement information through a wireless terminal separated from the main body worn on the wrist.

With the continued interest in health, various types of blood pressure measuring devices have been developed. Blood pressure measurement methods include a stethoscope (Korotkoff sounds), an oscillometric (oscillometric), and tonometric (tonometric) method. The auscultation method applies sufficient pressure to the body part through which arterial blood flows to block the flow of blood, and then decompresses the blood pressure. The pressure at the first pulse is measured by systolic pressure and the moment the pulse disappears. The pressure of diastolic pressure is measured by diastolic pressure.

Oscillometric and tonometric methods are applied to digitized blood pressure measurement devices. Like the stethoscope method, the oscillometric method detects the pulse wave generated in the process of sufficiently pressurizing a body part through which arterial blood flows so that blood flow in the artery is blocked, and decompressing it at a constant speed, or pressurizing the body part at a constant speed. Measure your systolic and diastolic blood pressure. 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, or the pressure when the rate of change of pulse wave amplitude changes rapidly may be measured by systolic blood pressure or diastolic blood pressure. . In the process of depressurizing at a constant speed after pressurization, systolic blood pressure is measured before the pulse wave amplitude is maximum, and diastolic blood pressure is measured later than the moment when the pulse wave amplitude is maximum. In contrast, 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.

The tonometric method applies a certain pressure to the body part that does not completely block the blood flow of the arteries, and measures blood pressure continuously by using the size and shape of the pulse wave generated at this time. Tonometric blood pressure measurement can be burdensome for the subject because it requires continuous body pressure for a long time.

On the other hand, recently, various blood pressure monitors that can be worn on the body so as to perform such a blood pressure measurement at all times have been developed. However, in the case of the wearable type blood pressure measuring device, the display unit for displaying the measured blood pressure information is also integrally formed, thereby increasing the size of the device.

In addition, the measurement accuracy can be increased when the breathing stops during blood pressure measurement, the wearable blood pressure meter has a problem that the measurement accuracy may be reduced because there is no function to inform the wearer of the blood pressure measurement state every blood pressure measurement cycle.

The present invention was devised to improve the above problems, by separating the component for measuring blood pressure and the part for collecting and displaying the measured information to simplify the structure for the wearing part at all times to increase the measurement accuracy to the wearer The purpose of the present invention is to provide an electronic blood pressure monitor using Bluetooth that can inform the measurement time.

In order to achieve the above object, the electronic sphygmomanometer using Bluetooth according to the present invention is formed to be worn on the arm including the wrist, and measures the blood pressure of the wearer and transmits a signal wirelessly by a Bluetooth communication method; It is separated from the main body, and formed to communicate wirelessly with the main body by Bluetooth communication to control the measurement conditions of the main body, collect the blood pressure measurement information measured by the main body wirelessly, and through the display unit And a wireless terminal capable of displaying blood pressure measurement information.

Preferably, the main body and the sensing unit is formed on the band to be worn on the arm including the wrist to measure the blood pressure of the wearer; A pressurizing actuator mounted to the band so that the sensing unit pressurizes and depressurizes the arm including the wrist of the wearer; A terminal Bluetooth communication module installed in the band to communicate with the wireless terminal in a Bluetooth manner; A terminal control unit controlling the pressure actuator according to a measurement cycle condition received from the wireless terminal to process the blood pressure information received from the sensing unit to be transmitted to the wireless terminal through the terminal Bluetooth communication module; And an alarm unit for controlling the terminal controller to output sound alarm information corresponding to a guide message for temporarily stopping the breathing when the blood pressure measurement cycle is reached.

The wireless terminal is a mobile communication terminal equipped with a remote Bluetooth communication module that communicates wirelessly with the terminal Bluetooth communication module and is capable of making a call. The main body is equipped with a blood pressure information management module configured to support setting of a driving condition including a blood pressure measurement cycle and an analysis display condition for the collected blood pressure information.

According to the electronic sphygmomanometer using Bluetooth according to the present invention, the measurement accuracy can be increased by inducing the wearer to stop breathing through an alarm sound that informs every measurement cycle while being worn on the arm including the wrist and supporting Bluetooth communication. It provides convenience in use because it can receive measurement information using a mobile phone, a mobile communication terminal.
