Claim Text:
1. A medical mask apparatus using optical fibers for projecting a fine laser beam to the skin to activate skin cells and expedite circulation of blood in the skin, the medical mask apparatus comprising: a laser light source generator for generating and supplying a laser beam having a predetermined wavelength band; a plurality of optical fibers branched from the laser light source generator; and a mask body having a cover portion having a predetermined area such that the cover portion covers a portion of a face and in which a portion of distal ends of the optical fibers are exposed along the entire cover, optical fiber connectors fixing the optical fibers to the mask body, the optical fiber connectors having a through-hole wherein a first portion of the through-hole at an input end of the connector has a first diameter, a second portion of the through-hole at a distal end of the connector has a second diameter, and an intermediate connecting portion of the through-hole between said first portion and said second portion has a tapered diameter, the input end of the optical fibers being inserted into the first portion and the output end of the optical fibers being inserted into the second portion; wherein an electro-optic material is coated on output ends of the optical fibers such that an output of the output ends of the optical fibers is controlled by an external electrical signal, and the output ends of the optical fibers have a diameter smaller than that of an input end of the optical fibers connected to the laser light source generator such that fine projection is allowed, said optical fibers including a core and a cladding, the core being tapered such that a diameter of an output end of the core is 70±5 μm when a diameter of an input end of the core is 550±55 μm, and the cladding being tapered such that a diameter of an output end of the cladding is 80±10 μm when a diameter of an input end of the cladding is 600±60 μm.
