Abstract: To provide an ultraviolet ray irradiation device which, when an operator inserts a glove to the device, prevents irradiation of ultraviolet rays to the outside thus further enhancing safety. An ultraviolet ray irradiation device includes: a sterilization chamber housing having an insertion opening through which a hand on which a glove is mounted is inserted into a sterilization chamber; an ultraviolet ray irradiating unit which irradiates ultraviolet rays to the chamber; ultraviolet ray blocking elastic bodies disposed so as to traverse an insertion direction of the hand, and allowing the hand to penetrate the elastic bodies; and a frame body supporting peripheral edge portions of the stacked elastic bodies. A plurality of cuts are radially formed in the elastic bodies. A plurality of elastic members are formed between the cuts. The respective elastic bodies are mounted on the frame body such that the cuts are displaced from each other.

Abstract: To provide an ultraviolet ray irradiation device by preventing leakage of ultraviolet rays from an insertion opening through which a hand on which a glove is mounted is inserted into a sterilization chamber. The device includes: an ultraviolet ray blocking balloon disposed in an insertion opening; a pressurized gas supplying and discharging device which supplies a gas under pressure to the balloon and discharges from it; an insertion depth detection unit which outputs an insertion hand depth detection signal; a controller of an ultraviolet ray irradiation and a pressurized gas supplying and discharging, wherein the balloon forms an opening which allows an insertion and a removal of the hand before the gas is supplied, and it is inflated with the supply of the gas so as to be brought into close contact with a wrist portion of the glove, and it is deflated with a discharge of the gas.
