A monitoring device for monitoring the vital signs of a user is disclosed herein. The system provides one or more handpieces, each driven driven by a pressurized nitrogen gas contained in a portable tank. A spring-mounting portion is in the form of a flat plate and extends from the door body and has one end face in which opens an insertion hole formed therein for having a foremost end of a spring member inserted therein. Then, the electrodeposition chamber is filled with an electrodeposition coating solution, and electrodeposition coating is performed. A frame including text is then rendered in which a glyph string texture object is created. Optionally, the amplification reagent, comprising a plurality of the binding ligands, is contacted with labeled receptor molecules thereby to complex a plurality of labeled receptor molecules to the amplification reagent, and the labeled receptor molecules complexed to the amplification reagent are detected.
