A kind of newborn's jaundice irradiation therapeutic device, comprising one to coat the circuit unit in a neonatal coating unit and the setting what coating unit. The coating unit includes one towards the newborn and the first layer of light-permeable and one combines the second layer on the what first layer. The circuit unit is arranged the what first layer and second interlayer and including on a flexible circuit board, and most interval setting what flexible circuit boards and towards the light-emitting diode of the first layer. Through the design of the coating unit and the flexible circuit board, make the utility model that can directly coat newborn, improve irradiation efficiency, cooperate what the grade light-emitting diodes had high directivity and a flexible circuit board to block effect again, influence of the light to newborn's eye is reduced, and the utility model can lightly take suitable newborn and treat at home.一種新生兒黃膽照光治療裝置,包含一用以包覆一新生兒的包覆單元,及一設置於該包覆單元內的電路單元。該包覆單元包括一朝向該新生兒且可透光的第一層,及一結合於該第一層上的第二層。該電路單元設置於該第一層與該第二層間並包括一軟性電路板,及多數間隔設置於該軟性電路板上且朝向該第一層的發光二極體。透過該包覆單元及該軟性電路板的設計,使本新型可直接包覆新生兒,提高照光效率,再配合該等發光二極體具有高指向性以及該軟性電路板的遮擋作用,減少光線對新生兒眼部的影響,且本新型輕巧可攜適合新生兒居家治療。
