Abstract
A disposable lancing device including: a lancet housed in a housing and urged by a spring member such that a puncture member provided at a distal end of the lancet is adapted to extend out from the housing so as to carry out a puncturing operation; a locking ring disposed within the housing such that the lancet is allowed to displace in an extension direction through the locking ring; a locking protrusion provided to the lancet and adapted to be engaged by the locking ring so as to hold the lancet in a puncture-ready position located deep in the housing with the spring member being compressed; and an operating member adapted to carry out the puncturing operation by rotating the locking ring so as to disengage the locking protrusion from the locking ring and displace the lancet in the extension direction by means of the spring member.
