Claim:
A safety lancet for preventing reuse, comprising: an upper case and a lower case coupled to one another to define a space of a certain volume therein, and defining through-holes at a front end thereof to enable a lancet needle to be exposed therethrough; a moving block provided to be movable within the cases and including the lancet needle formed at a front end thereof; a guide disposed at a rear end of the moving block within the cases, and including an anti-reverse ledge at a front end thereof to selectively restrict reverse movement for reloading of the moving block; a pressing plate pivotably mounted to the upper case on a pivot support that is an axis, and including a stopper projecting downward at a front end thereof on which the moving block is caught, and a pressing projection at a rear end thereof for pressing the guide; a seating recess defined in a bottom surface of the lower case, in which the guide that is pressed by the pressing plate descends and is seated and is prevented from ascension; and a resilient spring for supporting the rear end of the moving block with a predetermined resilient force, wherein the moving block further includes guide projections projecting from either sidewall thereof, and the cases further include guide grooves defined horizontally in inner walls thereof corresponding to the guide projections to guide the guide projections.
