Abstract
Lancet device that includes a body. A front cover includes a skin engaging end that includes a lancet opening through which a lancet needle extends. A holding member is movably mounted within the body. The holding member includes a front end and a rear end. The front end is configured to receive a lancet. A main spring is disposed between the front and rear ends of the holding member. A first stop surface is arranged on a front portion of the holding member. A second stop surface is axially retained to a front portion of the body. At least partial rotation of the front cover causes the skin engaging end to move axially relative to the second stop surface.
Claims45
A lancet device, comprising:
- a body;
- a trigger movably mounted to the body;
- a front cover removably mounted to the body and comprising a skin engaging end that includes a lancet opening through which a lancet needle may extend;
- a holding member movably mounted within the body and comprising a front end and a rear end;
- a main spring disposed inside the body between the front and rear ends of the holding member;
- the front end being configured to receive a lancet;
- a first stop surface that moves with the holding member and being arranged closer to the front end of the holding member than to the rear end of the holding member;
- a second stop surface non-movably coupled to the body;
- and
- the second stop surface extending inwardly from the body and being arranged closer to a front end of the body than to a rear end of the body and between the first stop surface and the skin engaging end,
- wherein at least partial rotation of the front cover causes the skin engaging end to move axially relative to the second stop surface, and
- wherein contact between the first and second stop surfaces defines a puncturing position of the lancet needle.
