  • Research Breakthroughs: Astragalus Newborns Can Receive LED Phototherapy At Home
    Jun 11, 2018

    With the increasing popularity of wearable devices and the Internet of Things, its application scope is not limited to 3C consumer products. In the future, more flexible and portable wearable smart products will be launched in succession. Recently, students from the University of Rhode Island (URI) have become students. A medical jumpsuit that incorporates LED phototherapy was developed so that neonates with jaundice can receive phototherapy at home, and doctors can also receive their physiological data remotely.


    Due to problems with the liver or spleen, patients with jaundice cannot normally metabolize bilirubin in the blood, resulting in yellowing of the eyeball and the skin. At present, the main treatment method for newborns of Astragalus is the “phototherapy box”. The lamps in the box are used to decompose the bilirubin. However, the inner baby cannot touch the parents during treatment, and it is necessary to use protective glasses to protect the eyes.

    The wearable device named "Jaundice Suit" is a baby's jumpsuit with hundreds of LED lights. It can cover baby's arms, legs, and torso, and the jumpsuit can be networked and collect physiological data of the human body. Internal LED lights can also be remotely controlled. R&D student Joshua Harper said the device compensates for past equipment.


    The built-in LED light of Jaundice Suit can decompose the bilirubin in the baby's body and prevent the children's eyes from being damaged by the light therapy. In the medical research, the doctor can remotely measure the heart rate and activity status, and can record the patient's data outside the hospital. It is easier to participate in nursing. However, its disadvantage is that it covers only the trunk and limbs and requires a longer treatment time.

    Huang Yier LED phototherapy research has been effective


    The Swiss Federal Institute for Materials Testing and Development (EMPA) also had similar research results in early November last year. It developed a wearable LED phototherapy pajamas for newborn babies of the Astragalus membranaceus, using special weaving methods to combine optical fibers with textile technology and set them with LEDs. It is the light source of the optical fiber guide tube, which controls the weaving angle so that the light wavelength is maintained at about 470 nm and can be shot onto the skin.


    Neonatal jaundice is one of the common diseases of infants. All countries have invested in related research. With the advancement of LED technology, LED light therapy has also emerged. According to a 2015 study conducted by the Aalborg University Hospital in Denmark, a blue LED with a wavelength of 459nm and a green LED with a wavelength of 497nm have therapeutic efficacy for jaundice.
