Description

Apparatus for measuring pulse with adjustable measuring point according to wrist thickness}

The present invention relates to a pulse measuring apparatus that can adjust the measurement position according to the thickness of the wrist, in particular, when measuring the pulse in the vicinity of the wrist, the measurement according to the wrist thickness for adjusting the pulse measuring position due to the thickness of the wrist different for each person The present invention relates to a pulse measuring device capable of adjusting a position.

The present invention is derived from the research conducted as part of the IT source technology development project of the Ministry of Knowledge Economy and the Ministry of Information and Telecommunications Research and Development. [Task management number: 2008-F-048-01, Task name: Wearable for U-computing space collaboration Personal Companion Technology Development].

Recently, interest in the healthcare and silver industries has increased, and biosignal measurement technology has been developed accordingly. There are various methods of measuring the pulse, and the method of measuring the pulse using an optical signal mainly uses a method of measuring a finger or a wrist. Currently widely used pulse measuring devices include a finger-type pulse measuring device, a wrist-type pulse measuring device of Exmocare, and a wrist-type pulse measuring device of a beat computer.

Here, the wristwatch type pulse measuring device is a wrist worn type, the beat computer is a sensor for measuring the pulse in the vicinity of the wrist, etc. Exmocare's product is a sensor for measuring the pulse near the wrist. Here, the pulse measuring device measures the user's pulse using a plurality of sensors.

In addition, the pulse measuring device can continuously perform the pulse sensing, it is associated with the service sent to the health care server through the measured data wireless communication. The pulse measuring device is implemented in a wrist wearing form and is easy to carry, and there is an advantage of being able to manage his or her health condition even when outdoors.

However, since the wrist wearable pulse measuring apparatus has a different thickness of the wrist for each person who wears the pulse measuring apparatus, the pulse measuring position is different.

That is, the pulse measuring apparatus measures the pulse using infrared rays of a specific wavelength of the optical sensor unit. Since the positions of blood vessels reflecting or scattering infrared rays of a specific wavelength vary from person to person, the pulse measuring position must be corrected every time the pulse is measured. If the pulse is measured without correcting the pulse measuring position, an incorrect pulse measuring result is obtained.

In order to overcome this, the problem was solved by measuring the pulse rate using two sets of optical sensors slightly separated from Exmocare products.

However, the use of two sets of optical sensors increases the power consumption by that, which causes a problem that the use time is significantly reduced. Moreover, this method does not fully overcome the inaccuracies in pulse measurement due to the diversity of human wrist size and the location of blood vessels.

On the other hand, in the product of the bit computer, the optical sensor is designed to measure the pulse on the upper part of the wrist, but this attempt does not completely overcome the inaccuracy of the pulse measurement due to the diversity of blood vessels passing through the human wrist.
