Puncture needle cartridge and lancet for blood collection
First Claim
1. A puncture needle cartridge, comprising:
- a bottom case in which a plurality of puncture needles are arranged in parallel such that respective puncture needles are provided independently of each other in said bottom case, said bottom case having an inner wall and an upper opening, and each of said puncture needles having an end that is fixed to said inner wall of said bottom case;
a slide cover that is slidable with respect to said bottom case so as to close said upper opening of said bottom case; and
a puncture needle support that is integrated with said slide cover so as to move together with said slide cover and support said puncture needles, said puncture needle support comprising a convex portion that is positioned and arranged such that when said slide cover is slid in a direction of sliding, said convex portion moves together with said slide cover and engages said puncture needles to push up said puncture needles one by one to a predetermined angle in response to said slide cover sliding with respect to said bottom case.

Abstract
A lancet is pressed against a puncture needle cartridge while fitting a puncture needle loading inlet of the lancet to the axis of a puncture needle on the puncture needle cartridge. In order to facilitate the operation, one of plural puncture needles, arranged in parallel, is tilted up from its initial position at a predetermined angle, and the puncture needle is guided into a puncture needle holding rod of the lancet. Simultaneously, the puncture needle is pressed up to a position where the rear end part of the needle pushes the bottom surface of a puncture needle loading chamber of the puncture needle holding rod, whereby the puncture needle is loaded. When discarding a used puncture needle, the puncture needle is inserted into a lancet guide member of the puncture needle cartridge, whereby the puncture needle is reliably captured to be discarded.
