Endcap for a Sampling Device
First Claim
1. A lancing device for collecting a sample of body fluid from a sampling site on the skin of a subject, said lancing device comprising an outer body housing and a lancet, the lancet being movable between a first position within the outer body housing and a second position wherein at least a sharp tip portion of the lancet extends through an opening in the outer body housing, and wherein the opening in the outer body housing has a non-circular periphery comprising a plurality of inwardly and outwardly directed lobes.

Abstract
A tip portion or endcap for a lancing device having a non-circular opening to provide tension and pressure upon the patient'"'"'s skin before and/or during lancing of the skin for sample collection. In example embodiments, the endcap is shaped to prevent the lancet body from sticking within the hole or passing through the hole. The endcap may also be shaped to allow it to be used at various lancing sites on the body without changing the endcap.

- 11. An endcap for a lancing device, said endcap comprising a first end for connection to the lancing device, and a second end defining an opening through which a sharp tip of a lancet can pass, the opening having a non-circular periphery comprising a plurality of inwardly and outwardly directed lobes.

20. A method for acquiring an increased volume of analytic fluid from a sampling site, the method comprising the steps of:
-
providing a lancing device with an endcap defining a non-circular opening; placing the lancing device against the skin so that the skin is in communication with the non-circular opening; applying sufficient pressure on the lancing device to cause tension upon the skin within the non-circular opening; triggering the lancing device; and continuing to apply pressure upon the skin with the lancing device while fluid is extracted from the sampling site.

22. A method of reducing the sensation of pain by a subject during a lancing procedure, said method comprising contacting a skin surface at or adjacent a sampling site with an irregular lobed contact surface, wherein the step of contacting a skin surface at or adjacent a sampling site with an irregular lobed contact surface comprises contacting the skin surface with at least one outwardly-projecting, non-planar lobe having a sharply-pointed distal tip.
