Adjustable depth lancing device
First Claim
1. A lancing device, comprising:
- a housing having an endcap defining an opening; and
a lancing element having a needle with a point movable between a retracted position and one of at least two extended positions with the needle point extending through the opening, wherein the needle point extends a first distance from the endcap when in a first one of the extended positions and the needle point extends a second distance from the endcap when in a second one of the extended positions; and
a means for adjusting the distance that the needle point extends from the endcap between the first distance and the second distance.

Abstract
A lancing housing has an endcap with an opening, and a lancing element has a needle that extends through the opening and beyond the endcap an adjustable distance selected to provide the desired depth of needle penetration. In exemplary embodiments, the distance the needle extends from the endcap is adjusted by a removable raised ring on the endcap, projections and cooperating recesses for positioning the endcap spaced apart from the housing, multi-positionable lancing element stops on the inside of the endcap, or a flip-out spacer adjacent the endcap. In preferred form, a disabling mechanism prevents re-arming the device after a single use. Additionally, a method of lancing the skin of a subject is provided for use with any adjustable penetration depth lancing device.

8. A lancing device, comprising:
-
a housing having an endcap defining an opening and a raised ring surrounding at least a portion of the opening; and
a lancing element having a needle point movable between a retracted position and one of at least two extended positions with the needle point extending through the opening, wherein the needle point extends a first distance from the housing raised ring when in a first one of the extended positions and the needle point extends a second distance from the housing endcap when in a second one of the extended positions, wherein the raised ring is detachable from the endcap, and the needle point extends the first distance from the housing raised ring when the ring is attached to the housing and the needle point extends the second distance from the housing endcap when the ring is removed from the housing. - View Dependent Claims (9, 10)

11. A lancing device, comprising:
-
a housing having a body and an endcap defining an opening;
a lancing element having a needle point movable between a retracted position and one of at least two extended positions with the needle point extending through the opening, wherein the needle point extends a first distance from the endcap when in a first one of the extended positions and the needle point extends a second distance from the endcap when in a second one of the extended positions; and
one or more recesses that receive one or more projections for coupling the housing endcap to the housing body, the recesses and the projections defined in or extending from the housing body and the housing endcap to permit repositioning the endcap on the body to expose different lengths of the lancing element needle, wherein the needle point extends the first distance from the endcap when the endcap is coupled to the housing in a first position and the needle point extends the second distance from the endcap when the endcap is coupled to the housing in a second position. - View Dependent Claims (12, 13, 14, 15, 16)

17. A lancing device, comprising:
-
a housing having a body and an endcap rotationally coupled to the body and defining an opening;
a lancing element having a needle with a point movable between a retracted position and one of at least two extended positions with the needle point extending through the opening, wherein the needle point extends a first distance from the endcap when in a first one of the extended positions and the needle point extends a second distance from the endcap when in a second one of the extended positions; and
at least two stops defined on or extending from an inside face of the endcap for selectively contacting a cooperating portion of the lancing element to limit lancing element travel, wherein the needle point extends the first distance from the endcap when the endcap is rotated so that one of the stops contacts the lancing element and the needle point extends the second distance from the endcap when the endcap is rotated so that another one of the stops contacts the lancing element. - View Dependent Claims (18, 19, 20, 21)

22. A lancing device, comprising:
-
a housing having an endcap defining an opening;
a lancing element having a needle with a point movable between a retracted position and one of at least two extended positions with the needle point extending through the opening, wherein the needle point extends a first distance from the endcap when in a first one of the extended positions and the needle point extends a second distance from the endcap when in a second one of the extended positions; and
a flip-out spacer pivotally mounted adjacent an inside face of the endcap for contacting a cooperating portion of the lancing element in a first position of the flip-out spacer to limit lancing element travel and for avoiding contact with the lancing element in a second position of the flip-out spacer, wherein the needle point extends the first distance from the endcap when the flip-out spacer is in the first position and the needle point extends the second distance from the endcap when the flip-out spacer is in the second position. - View Dependent Claims (23, 24, 25)
