Abstract
Lancet device including a skin engaging end that includes a lancet opening through which a lancet needle may extend, a movably mounted holding member configured to receive a lancet, and a combined triggering and cocking system structured and arranged to move the holding member to a retracted position during a cocking phase and to cause the holding member to move to an extended position during a triggering phase. A method of puncturing a surface of skin using the lancet device includes disposing the skin engaging end against a user's skin and manually activating the combined triggering and cocking system. 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.
Claims21
A multi-use lancet device comprising:
- a skin engaging end that includes a lancet opening through which a lancet needle may extend;
- at least one compression spring comprising one of;
- a center axis oriented parallel to an axis of the lancet opening;
- and/or
- a center axis oriented perpendicular to an axis of the lancet opening;
- a movably mounted holding member configured to receive a replaceable lancet;
- a combined triggering and cocking system associated with the at least one spring and being structured and arranged to move the holding member to a retracted position during a cocking phase and to cause the holding member to move to an extended position during a triggering phase;
- and
- a portion of the combined triggering and cocking system being located outside a housing of the lancet device and being located closer to the skin engaging end than the compression spring.
A lancet device comprising:
- a skin engaging surface that includes a lancet opening through which a lancet needle may extend;
- a lancet needle movable parallel to a central axis of the lancet opening;
- a spring that is compressed when the lancet needle moves from an original and/or intermediate position to a retracted position;
- a combined triggering and cocking system comprising one portion disposed outside the lancet device and another portion disposed inside the lancet device;
- the portion arranged outside being:
- movable relative to a sidewall of the lancet device;
- and
- closer to the skin engaging surface than the spring in the original position;
- the other portion being structured and arranged to cause movement of the lancet needle to the retracted position during a cocking phase and to allow the lancet needle to move to an extended position during a triggering phase,
- wherein, when a user moves the portion disposed outside, the other portion moves from one side of the central axis to another side of the central axis during at least the cocking phase, and
- wherein the lancet needle is movable back to the original position and/or intermediate position after triggering of the lancet device.
A multi-use lancet device comprising:
- a skin engaging surface that includes a lancet opening through which a lancet needle may extend;
- a lancet needle movable parallel to a central axis of the lancet opening;
- a combined triggering and cocking system comprising two portions disposed outside the lancet device;
- each of the two portions arranged outside being movable relative to a sidewall of the lancet device;
- wherein, when a user moves the two portions disposed outside, the lancet needle first moves to a retracted position and then a triggering of the lancet device occurs whereby the lancet needle is automatically caused to move to a puncturing position, and
- wherein the lancet needle is movable back to an original position and/or intermediate position after triggering of the lancet device.
A multi-use lancet device comprising:
- a housing having a skin engaging end that includes a lancet opening through which a lancet needle may extend;
- a compression spring mounted within the housing;
- a movably mounted holding member configured to receive a replaceable lancet;
- a combined triggering and cocking system structured and arranged to move the holding member to a retracted position during a cocking phase and to cause the holding member to move to an extended position during a triggering phase;
- and
- a button portion of the combined triggering and cocking system being located outside the housing and being located closer to the skin engaging end than both the compression spring and the holding member.
