Assembly for adjusting pricking depth of lancet
First Claim
1. An assembly which is attached to an ejector which ejects a lancet having a pricking element protruding therefrom along an ejection axis, said assembly adjusting a pricking depth of the pricking element into an object to be pricked, the assembly comprising:
- a cap member adapted for attachment to the ejector, the cap member having a stop means which stops movement of the lancet during ejection by abutment of an end of the lancet from which the pricking element protrudes against the stop means,a cover element having an opening against which the object to be pricked is placed, the pricking element extending through the opening when the lancet is ejected, andan adjusting element disposed between and engaging the cap element and the cover element, anda distance between the stop means and the opening along the ejection axis is changeable by rotation of the adjusting element around the ejection axis.

Abstract
There is provided an assembly capable of more simply adjusting a pricking depth of a pricking element and being mounted onto an injector.
The assembly comprises a cap element enabled to be mounted onto the injector and having a stop means constructed such that an end of a lancet from which the pricking element protrudes abuts against the stop means after ejecting the lancet so that movement of the lancet is stopped while the pricking element is exposed outside out of the cap element, a cover element through which the pricking element exposed outside extends and which has an opening against which an object to be pieced is placed, and a adjusting element which engages the cap element and the cover element between these elements, and a distance between the stop means and the opening along a direction of the lancet ejection is changed by rotation of the adjusting element around an axis of the direction of the lancet ejection.
