Wearable phototherapy device

Abstract

Disclosed is a wearable phototherapy device. The wearable phototherapy device comprises a flexible housing, at least one OLED light source, at least one triplet-triplet annihilation up-conversion (TTA-UC) material layer and an electric drive connecting device, wherein the flexible housing has an inner surface and an outer surface; the at least one OLED light source is arranged on the inner surfaceof the flexible housing, and the light source comprises a light-emitting surface and at least one OLED device; the at least one triplet-triplet annihilation up-conversion material layer is coupled tothe optical path of the OLED light source; and the electric drive connecting device is electrically connected with the light source. The phototherapy device can be worn close to a body and is beneficial to establishment of an early parent-child relationship. Meanwhile, the OLED is lighter and thinner, and the skin of the baby is not burnt due to heating. Large-area long-time treatment can be carried out by using red, green and yellow OLEDs with high efficiency and long service life. Therefore, compared with a traditional phototherapy box adopting an LED or a blue light OLED, the phototherapydevice has more advantages in treatment of neonatal jaundice.

Description

technical field [0001] The present invention relates to a phototherapy device, such as a phototherapy device for treating neonatal jaundice. More particularly, it relates to a wearable device that uses a red, green or yellow OLED disposed on the inner surface of a flexible housing as a light source, and uses a triplet-triplet annihilation upconversion (TTA-UC) material to emit the light source An OLED phototherapy device that converts red, green or yellow light into blue light to treat neonatal jaundice. Background technique [0002] Neonatal jaundice is one of the most common neonatal conditions, which can be seen in more than 50% of full-term infants and more than 80% of premature infants, accounting for 20-40% of hospitalized neonates. Neonatal jaundice refers to a disease characterized by yellow staining of the skin, mucous membranes, and sclera due to abnormal bilirubin metabolism in the neonatal period, resulting in elevated bilirubin levels. In severe cases, high bil...

Problems solved by technology

First of all, fluorescent lamps are filled with mercury vapor in glass tubes, which are bloated and have heat dissipation problems. They can only be integrated into the cabinet and cannot be used close to the body. At the same time, glass is fragile and mercury vapor is poisonous, so it is not suitable to be near babies.

Secondly, the luminous efficiency of fluorescent lamps is not high, and the amount of light is further reduced when used at a long distance, which reduces the treatment efficiency

Third, due to the overall exposure, large-scale exposure to blue light will also cause side effects such as inducing skin cancer, affecting circadian rhythms, and lowering body temperature. In order to avoid damage to vision, the baby must wear eye masks. Careless use may Cause accidents such as eye damage, skin allergies, and even suffocation

In contrast, top-emitting blue OLEDs at 1000cd / m 2 At only 5lm / W, LT95 can barely reach 1000 hours
