Abstract

The present invention relates to a disposable lancing device which can prevent infectious possibility because the device may not be reused after a lancet is shot.

The lancing device injecting a lancet into a skin by means of the elasticity stored in a elastic member, comprises: a lancet holder having a front portion holding a lancet, a rear portion engaged with the elastic member, and a protruding portion configured to have a rectangular cross section in the bottom; a pushing member having a latch of the rectangular cross section to fix the lancet by supporting the front surface of the protruding portion of said lancet holder before using the lancet, and supporting the rear surface of the protruding portion of said lancet holder after using the lancet thereby preventing the lancet from retreating; and a body receiving the lancet holder inward and engaged with the pushing member to outward.

Claims

1. A lancing device injecting a lancet into a skin by means of the elasticity stored in a elastic member, comprising:

a lancet holder having a front portion holding a lancet, a rear portion engaged with the elastic member, and a protruding portion configured to have a rectangular cross section in the bottom;

a pushing member having a latch of the rectangular cross section to fix the lancet by supporting the front surface of the protruding portion of said lancet holder before using the lancet, and supporting the rear surface of the protruding portion of said lancet holder after using the lancet thereby preventing the lancet from retreating; and

a body receiving the lancet holder inward and engaged with the pushing member to outward.

2. The lancing device according to claim 1, wherein the body has a cap at the fore for guiding the lancet forward and adjusting the gap between the body and said cap by rotation.
