Definitions
- the present invention relates generally to medical devices and procedures, and more particularly to lancing devices for sampling blood or other bodily fluids.
- the invention more particularly relates to an end cap for use in conjunction with a lancing device that allows for the collection of an increased volume of blood or bodily fluid to be sampled.
- a lancet having a sharp lancing tip typically is mounted, permanently or releasably, to the drive mechanism of a lancing device.
- the drive mechanism includes one or more springs, cams, motors, or other mechanism(s) for moving the lancing tip from a retracted position shielded within a housing of the lancing device to an extended position outside of the housing for lancing the subject's skin.
- the lancing device may also include a cocking mechanism for arming the drive mechanism, and/or a triggering mechanism for firing the device.
- the housing of the lancing device typically includes an endcap with an opening through which the lancing tip extends in its extended position. The endcap may be releasably or permanently attached to the remainder of the housing, or can comprise an integral part of the housing.
- the fingertips have a greater density of nerve endings than alternate lancing sites, resulting in greater pain sensation from fingertip lancing than lancing at alternate sites.
- alternate lancing sites typically contain a lower density of capillaries or a deeper capillary bed than the fingertips, alternate lancing sites often yield insufficient sample sizes or are prone to premature closure.
- the present invention is an endcap for a lancing device that enables collection of an increased volume of blood or other body fluid to be sampled from a lancing site of a human or animal subject.
- the device of the present invention is suitable for use at fingertip lancing sites, but is also well suited for use at alternate lancing sites such as the forearm and/or earlobe.
- the invention is a sampling method for increasing collected sample size of blood or other body fluid from a lancing site.
- the present invention is an endcap for a lancing device.
- the endcap preferably includes an opening for passage of at least a sharp tip portion of a lancet, a contact face surrounding the opening, and at least one surface feature on the contact face adjacent the opening for applying pressure to tissue surrounding a lancing site by rocking of the contact face in contact with the tissue surrounding the lancing site.
- the invention is an endcap for a lancing device, the endcap preferably including an outwardly-curved contact face for rocking contact with tissue surrounding a lancing site, and at least one slotted opening through the outwardly-curved contact face, the slotted opening being narrower at a central portion than at extremities thereof.
- the invention is a lancing device for collecting a sample of body fluid from a sampling site on the skin of a subject.
- the lancing device preferably includes a lancet and a housing comprising an endcap, the lancet being movable between a first position within the housing and a second position wherein at least a sharp tip portion of the lancet extends through an opening in the endcap.
- the endcap preferably includes a contact face surrounding the opening and at least one surface feature on the contact face adjacent the opening for applying pressure to tissue surrounding the sampling site by rocking of the contact face in contact therewith.
- the invention is a lancing device for collecting a sample of body fluid from a sampling site on the skin of a subject.
- the lancing device preferably includes a lancet and a housing comprising an endcap, the lancet being movable between a first position within the housing and a second position wherein at least a sharp tip portion of the lancet extends through an opening in the endcap.
- the endcap preferably includes an outwardly-curved contact face for rocking contact with tissue surrounding the sampling site, and at least one slotted opening through the outwardly-curved contact face.
- the invention is a method of collecting a sample of blood or other body fluid, the method preferably including the steps of lancing the skin of a subject at a lancing site with a lancing device having a contact face including one or more surface contour features surrounding an opening; and rocking the lancing device with the contact face in contact with the skin surrounding the lancing site.

When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values . are expressed as approximations, by use of the antecedent "about,” it will be understood that the particular value forms another embodiment.
- Figure 1 shows one example embodiment of an endcap 10 for a lancing device according to the present invention.
- the endcap 10 preferably comprises a first end 12 for releasable or permanent attachment to the remainder of a housing of a lancing device.
- the endcap forms an integral part of the housing of the lancing device.
- the endcap 10 can be adapted for use with any of a variety of standard, commercially-available or later-developed lancing devices, by appropriate configuration of coupling or attachment features of the first end 12.
- the second end 14 of the endcap 10 preferably defines the opening 16 through which the sharp lancet tip projects in its extended position to penetrate the skin at the intended lancing site.
- the opening 16 is a slot extending substantially across the second end 14 of the endcap 10.
- the opening has a circular, triangular, rectangular, polygonal or other shape.
- the second end 14 of the endcap 10 preferably comprises an outwardly curved or convex contact face 20, with one or more raised surface features formed thereon.
- the surface features comprise a raised rim 22 surrounding the slotted opening 16, and a raised side projection 24 extending laterally outward from the contact face 20 along the central portion of both sides of the slot 16.
- the outer surfaces of the rim 22 and the projection 24 are preferably outwardly radiused to generally match the outwardly curved or convex contour of the contact face 20.
- the user after firing the lancing device, the user leaves the contact face of the endcap in contact with the skin around the lancing site, and rocks the lancing device, preferably in the plane of the slotted opening and raised rim.
- the outwardly curved or convex curvature of the contact face facilitates and guides this rocking motion.
- the device is preferably initially placed with its contact face in contact with the skin at the lancing site and held generally perpendicular to the skin surface during lancing, and then is rocked back and forth in contact with the skin in at least one plane of motion, wherein that plane of motion intersects a lengthwise axis of the overall lancing device and the center of the endcap's lancet opening.
- the endcap's lancet opening and/or the raised surface feature(s) on the endcap's contact face are preferably generally symmetric along either side of this plane of motion, and the endcap's contact face is curved along this plane of motion, whereby rocking of the lancing device in the plane of motion applies pressure symmetrically about the lancing site.
- the endcap embodiment of Fig. 1 is rocked in a plane of motion containing the lengthwise axis of the slotted opening 16
- the raised rim 22 and the central projection 24 will apply alternating pressure around the puncture site, directing subcutaneous fluid toward the puncture site and helping prevent premature closure of the puncture site, thereby enhancing collection of increased volume of blood or other body fluid to be sampled.
- Figures 2a and 2b show an endcap 30 for a lancing device according to another embodiment of the present invention.
- the contact face 32 of this endcap defines a generally circular central opening 34 for allowing passage of the sharp lancet tip.
- Contact ribs 36 are preferably provided, extending across the contact face 32 along either side of the opening 34.
- the distal faces of the contact ribs 36 are preferably convexly curved to facilitate and guide rocking of the lancing device in contact with the skin in a similar fashion to that described above.
- the inner edges of the contact ribs 36 are preferably curved or angled to define a central channel 38 that is wider at its center, around the opening 34, than at its outer edges along the periphery of the endcap.
- the contours of the contact face 32 and the contact ribs 36 preferably direct subcutaneous fluid toward the puncture site and help prevent premature closure of the puncture site, as the device is rocked back and forth, preferably in a plane of motion extending through the center of the opening and central channel, thereby enhancing collection of increased volume of blood or other body fluid to be sampled.
- Figures 3a and 3b show an endcap 50 for a lancing device according to yet another embodiment of the present invention.
- the contact face 52 of this endcap defines a generally circular central opening 54 for passing the sharp lancet tip.

- the user toggles, rocks and/or twists the lancing device with the contact face 52 in contact with the skin around the lancing site.
- the undulating contour of the contact face generates alternating tension and compression of the skin surrounding the lancing site, directing subcutaneous fluid toward the lancing site and helping prevent premature closure of the lancing site, thereby enhancing sample collection.
- FIG 4 shows an endcap 70 for a lancing device according to another embodiment of the present invention.
- the contact face 72 of this endcap defines a generally circular central opening 74 for passing the sharp lancet tip.
- the contact face 72 preferably comprises a pair of contact ribs 76, extending across the contact face 72 along either side of the opening 74.
- the distal faces of the contact ribs 76 are preferably convexly curved to facilitate and guide rocking of the lancing device in contact with the skin in a similar fashion to that described above.
- the inner edges of the contact ribs 76 are preferably curved or angled to define a central channel 78 that is narrower at its center, around the opening 74, than at its outer edges along the periphery of the endcap.
- FIG. 5 shows an endcap 90 for a lancing device according to still another embodiment of the present invention.
- This endcap includes a convex contact face 92 and a slotted opening 94 extending across at least a portion of the width of the contact face.
- One or more raised ribs or projections 96 are preferably provided, extending across at least a portion of the contact face 92, generally transversely or obliquely oriented relative to the lengthwise dimension of the slot 94.
- two raised ribs extend transversely across the slot 94, each rib having a first segment on one side of the slot and a second segment on the other side of the slot.
- FIG. 6 shows an endcap 110 for a lancing device according to another embodiment of the present invention.
- This endcap includes a convex contact face 112 and a cross-shaped opening 114 formed in the contact face.
- the opening 114 is formed by two or more slots intersecting at or near the center of their lengthwise dimensions, each slot being narrower at its central region than at its extremities.
- the lancing device is toggled or rocked after lancing, preferably in the plane of one or more of the intersecting slots forming the opening 114, subcutaneous fluid is directed and squeezed toward the central intersection of the slots of the opening.
- the inwardly-extending lobes 116 between the intersecting slots of the cross- shaped opening 114 can serve as a mechanical stop for the lancet, to limit the path of travel of the lancet at its extended position.
