First Claim
Patent Images
1. A pricking device comprising:
- (a) a lancet assembly comprising a lancet and a protective cover; and
(b) an injector assembly that has an injector body, and a plunger and a pusher which are disposed in the injector body and which ejects the lancet,characterized in that(1) the lancet comprises a lancet body, a lancet cap and a pricking member, the pricking member is disposed in the lancet body and the lancet cap while straddling those members, and a distal end portion of the pricking member is enclosed by the lancet cap;
(2) the protective cover is disposed around the lancet body, and it is able to move to a position, after pricking, around the distal end portion of the pricking member that protrudes forward from the lancet body;
(3) the plunger holds a rear end portion of the lancet body and ejects the lancet body so that the protruding distal end portion of the pricking member pricks a predetermined portion; and
(4) the pusher pushes, after pricking, the protective cover that is disposed around the lancet body so as to move it forward, and thereby the protective cover is located around the distal end portion of the pricking member that protrudes forward from the lancet body.

Abstract
A pricking device is provided that allows a protruding tip of a distal end portion of a pricking member to be shielded from surround as much as possible and removed from an injector assembly.
The lancet assembly 100 contains a lancet 101 and a protective cover 102, characterized in that
- (1) the lancet comprises a lancet body 104, lancet cap 106 and a pricking member 105, the pricking member is disposed in the lancet body and the lancet cap while straddling them members, and the distal end portion 124 of the pricking member is enclosed by the lancet cap; and
- (2) the protective cover is disposed around the lancet body, so that it is able to move to a position, after pricking, around the distal end portion of the pricking member that protrudes forward from the lancet body.
