Lancing device with pivoting end cap
An endcap for a lancing device, having a base portion and pivoting tip member pivotally mounted to the base portion. The base portion and the pivoting tip member each having openings therethrough which, when aligned, allow passage of a lancet tip. After lancing the skin at a sampling site, the lancing device is rocked back and forth, with a contact face of the pivoting tip member maintained in contact with the skin surrounding the sampling site to enhance sample collection and prevent premature wound closure.
1 . An endcap for a lancing device, the endcap comprising a base member having a first end for connection to the lancing device, and a pivoting tip member comprising a contact face having an opening therethrough, wherein the pivoting tip member is pivotally coupled to the base member.
2 . The endcap of claim 1 , wherein the contact face is concave.
3 . The endcap of claim 1 , wherein the pivoting tip member is connected to the base member by two pin connections on opposite sides of the endcap.
4 . The endcap of claim 1 , wherein the base member comprises an arcuate distal end.
5 . The endcap of claim 1 , wherein the arcuate distal end of the base member comprises a slotted opening for alignment with the opening in the contact face of the pivoting tip member to allow passage of the sharp tip of a lancet.
6 . A lancing device for collecting a sample of body fluid from a sampling site on the skin of a subject, said lancing device comprising 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 out of the housing, and wherein the endcap comprises a base portion and a pivoting tip member pivotally coupled to the base member.
7 . The lancing device of claim 6 , wherein the pivoting tip member comprises a contact face having an opening therethrough.
8 . The lancing device of claim 7 , wherein the base member comprises an arcuate distal end.
9 . The lancing device of claim 8 , wherein the arcuate distal end of the base member comprises a slotted opening for alignment with the opening in the contact face of the pivoting tip member to allow passage of the sharp tip of a lancet.
10 . The lancing device of claim 7 , wherein the contact face is concave.
11 . The lancing device of claim 6 , wherein the pivoting tip member is connected to the base member by two pin connections on opposite sides of the endcap.
12 . A method of lancing skin to collect a fluid sample, the method comprising:
placing a contact face of a pivoting tip member portion of a lancing device against a subject's skin at a sampling site;
lancing the skin at the sampling site; and
rocking the lancing device to cause the lancing device to pivot relative to the pivoting tip member, with the contact face maintained in contact with the skin around the sampling site.
