Blood lancet system for blood withdrawal for diagnostic purposes
First Claim
1. Blood lancet system for blood withdrawal for diagnostic purposes, comprisinga lancet and a pricking apparatus with a housing, a lancet holder movable in the housing for holding an exchangeable lancet, and a lancet drive for driving a pricking movement of the lancet on a predetermined pricking path, the housing comprises a cap to be attached at a forward end thereof in pricking direction, the cap being removable for removing a used lancet out of the housing, the lancet and the cap are adapted to be automatically coupled, during attaching the cap to the housing, by a coupling mechanism comprising matching coupling elements, thereby enabling the extraction of the lancet from the lancet holder without additional handling steps by removing the cap wherein the coupling mechanism comprises a movable ejector for ejecting the lancet, and a coupling element of the ejector and a corresponding coupling element of the cap are adapted to each other such that the cap is coupled to the ejector during attachment of the cap to the housing and during removal of the cap.

Abstract
Blood lancet system for blood withdrawal for diagnostic purposes with a housing, a lancet holder movable in the housing for holding an exchangeable lancet, and a lancet drive for driving the pricking movement of the lancet holder with the lancet contained herein. The housing has a cap at the front end in pricking direction which can be removed in order to remove a used lancet from the lancet holder.
The lancet and the housing cap are coupled, during the attachment of the housing cap, by a coupling mechanism comprising coupling elements matched to each other and enabling the extraction of the lancet from the lancet holder simultaneously with removing the housing cap.
