<P>PROBLEM TO BE SOLVED: To provide a disposable lancing device of novel construction capable of reliably and stably maintaining a puncture-ready position where a lancet is locked in a position to which a spring member is compressed, as well as carrying out a puncturing operation through unlocking of the lancet. <P>SOLUTION: The disposable lancing device 10, 100 employs a locking ring 72 as a separate element from a housing 12 and a lancet 14. By turning the locking ring 72 alone, it is possible to unlock the lancet 14 that has been urged by a spring member 16 while being held in the puncture-ready position, thereby carrying out the puncturing operation. Also, the lancet 14 can avoid being subjected to the operating force for carrying out the puncturing operation from a lateral direction, and catching due to deviation of the center axis of the lancet 14 or increase of frictional force against other components are prevented, thereby achieving the puncturing operation in a stable manner. <P>COPYRIGHT: (C)2012,JPO&INPIT |
