1. A lancet device comprising:
- a body;
a front cover 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;
the front end being configured to receive a lancet having the lancet needle;
a first spring structured and arranged to move the holding member between at least a retracted position and an extended position;
a second spring structured and arranged to move the holding member between at least an intermediate position and the retracted position; and
a push-button arranged on a rear end of the body,wherein, when the push-button is depressed, the second spring is compressed by the push-button, andwherein, when the push-button is released, the second spring expands and the holding member is caused to move to a trigger-set position via a force generated by the second spring, andwherein, when the holding member is caused to move to the trigger-set position by the release of the push-button, the first spring is caused to be compressed.

Abstract
Lancet device utilizing a body, a holding member configured to receive a lancet having the lancet needle, a first spring structured and arranged to move the holding member between at least a retracted position and an extended position, and a second spring structured and arranged to move the holding member between at least an intermediate position and the retracted position. The first spring is at least one of smaller in diameter than the second spring and compressible by expansion of the second spring. 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.

1. A lancet device comprising:
-
a body; a front cover 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; the front end being configured to receive a lancet having the lancet needle; a first spring structured and arranged to move the holding member between at least a retracted position and an extended position; a second spring structured and arranged to move the holding member between at least an intermediate position and the retracted position; and a push-button arranged on a rear end of the body, wherein, when the push-button is depressed, the second spring is compressed by the push-button, and wherein, when the push-button is released, the second spring expands and the holding member is caused to move to a trigger-set position via a force generated by the second spring, and wherein, when the holding member is caused to move to the trigger-set position by the release of the push-button, the first spring is caused to be compressed. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 50, 51, 52, 53, 54, 55, 56, 57, 58)

46. An adjustable depth of penetration lancet device, the lancet device comprising:
-
a body; a front cover 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; the front end being configured to receive a lancet having the lancet needle; a first spring structured and arranged to move the holding member between at least a retracted position and an extended position; a second spring structured and arranged to at least one of; move the holding member between at least an intermediate position and the retracted position; and cause compression of the first spring; a push-button member structured and arranged to cause compression of the second spring when the push-button is depressed and to cause compression of the first spring when the push-button is released; and the push button also being structured and arranged to move the holding member to the retracted position after a portion of the push-button is releasably connected to a portion of the holding member.

47. A lancet device comprising:
-
a body having a front end and a rear end;
a holding member configured to receive a lancet having the lancet needle;a first spring structured and arranged to move the holding member between at least a retracted position and an extended position; and a second spring structured and arranged to move the holding member between at least an intermediate position and the retracted position, wherein expansion of the second spring automatically causes compression of the first spring and movement of the holding member to the retracted position, and wherein, after the holding member moves to a trigger-set position, the lancet device is automatically triggered, wherein the first spring is arranged axially closer to the front end of the body than the second spring and is at least one of; smaller in diameter than the second spring; and compressible by expansion of the second spring. - View Dependent Claims (48)

49. A lancet device comprising:
-
a body; a movable lancet holding member structured and arranged to receive a removable lancet; and a cocking and triggering system structured and arranged to automatically cock and trigger the lancet device when activated by a user, wherein the cocking and triggering system includes a push-button arranged on a rear end of the body which, when depressed, compresses one spring and moves to a position so as to allow the push-button to releasably connect to the lancet holding member and, when released, releasably connects to the lancet holding member and moves the lancet holding member towards a trigger-set position and causes compression of another spring, and then automatically disconnects from the lancet holding member.
