Japan's newly developed LED light measurement sphygmomanometer

The Japanese university scheduled to deliver a speech that is "new generation of medical devices in Japan Summit 2013 - a new generation of sensors open up the future of health ~" " touching with a finger you can simply measure the blood pressure ~ 'phase shift method' to care revolution " on July 17, 2013.

The Japanese university show the sphygmomanometer，we just touch with a finger to measure blood pressure. The product has the advantage: no need to measure with oppressive, so infants and young children and the elderly can be measured easily blood pressure. In addition, when used in daily health management, but also eliminates the trouble with rolled oppression, can more easily measure blood pressure. Thus, " the major care equipment manufacturers having a high share in the sphygmomanometer field will come to repeatedly study for several days during the show,."

The blood pressure takes advantage of measured light and is equipped with a LED and a phototransistor, the phototransistor detects the reflected light emitted by the LED light. Specific principle is not announced, but according to Japanese universities introduced, it adopted the "phase shift" technique the Faculty of Engineering, Professor Sadao developed. Sadao said, "After using the phase shift method S / N will be substantially improved, so can be measured with high accuracy."

In MEDICA2012 on display, the Japanese university has received a lot of consulting from firm around the world in succession. According to the Sadao introduction, has recently succeeded in chip core single, including using data processing section of phase shift method. The current size is1cm2 square, " it is reduced to a few mm square so that materialize and can also be equipped with a portable terminal, which is also expected to use the flash LED smart phone is equipped with, through smart phone is to measure pulse rate and blood pressure" (tail stock Sadao) . Nihon University intends to cooperate with and begin to offer chips to enterprises in the year 2013,.

LED lights can be well applied with sphygmomanometer ，which indicates LED Lighting in addition can be integrated into art and design, science and technology and other fields, it can also combine the medical to make a contribution to our health, we can not help but marvel LED lighting magic, and now what the most widely used is the LED outdoor lighting, such as LED tunnel light also guarantees the safety for the driver in the tunnel， the LED tunnel light can provide more gentle and bright light to avoid the glare light the high pressure sodium lamp brings, it has the advantages of long life, waterproof, dustproof, resist-shock, high-definition features can be well qualified for the tunnel environment, Lead lighting has been improving the production and R & D team and using qualified LED chips, high power, drive, heat sink, shell and other materials to produce more environmentally friendly and energy saving a variety of LED lighting that can adapt to the environment where we live ，links to LED Tunnel Light product page www.lead-lighting.com/products/bid32-1.htm to find more outdoor lighting or return home to experience different feelings LED lighting bring.
