Adjustabable disposable/single-use lancet device and method
First Claim
1. A single-use lancet device, comprising:
- a body comprising a skin engaging end that includes a lancet opening through which a lancet needle extends;
a trigger mounted to the body;
a holding member movably mounted within the body and comprising a front end and a rear end;
the holding member being movable between a retracted position and an extended position;
a stop surface that moves with the holding member;
a cam disk comprising cam surfaces which can be contacted by the stop surface; and
the cam disk being configured to rotate at least partially about an axis that is not parallel to an axis running through at least one of the lancet opening and the holding member,wherein, once caused to move to the extended position by the trigger, the holding member is prevented from moving back to the retracted position, andwherein the single-use lancet device is usable for forming a skin puncture only once.

Abstract
Adjustable Single-use lancet device that includes a body. A trigger is mounted to the body. A skin engaging end includes a lancet opening through which a lancet needle extends. A holding member is movably mounted within the body and includes a front end a rear end. The front end receives a lancet needle. A stop surface moves with the holding member. A cam disk includes cam surfaces which can be contacted by the stop surface. The cam disk is configured to rotate at least partially. The cam disk rotates about an axis that is not parallel to an axis running through at least one of the lancet opening and the holding member. Once caused to move to the extended position by the trigger, the holding member is prevented from moving back to the retracted position. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
