Abstract: Provided is a light therapy device capable of further maximizing a scattering effect, having enhanced durability, and exhibiting energy uniformity sufficient for use as a light therapy device.

Abstract: The present invention relates to a device for coating the inside of an artificial blood vessel and, to explain more specifically, to a device for coating the inside of an artificial blood vessel inserted into the body of a human for a medical purpose, which is configured to be able to selectively coat just the inside of a lumen of the artificial blood vessel with a bioactive substance for inhibiting neointimal hyperplasia, in order to prevent a side effect, such as angiostenosis or inflammation, from occurring in an area connecting the artificial blood vessel and a blood vessel in the body.

Abstract: Provided is a shock reducing tape spring hinge including fixing members fixed to at least two objects, respectively, a thin shell type tape spring having both end portions that are fastened to the fixing members, respectively, and a shell-shaped damping plate aligned with the tape spring, the damping plate having both end portions that are fastened to the fixing members, respectively. The damping plate and the tape spring may be configured to connect the at least two objects being spaced through the fixing members, and the damping plate may be configured to reduce a deployment shock occurring when the tape spring is deployed.
